Sustainable energy

Sustainable energy is energy that is consumed at insignificant rates compared with its manageable collateral effects, especially environmental effects. Another common definition of sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs. Renewable energy is not a synonym of sustainable energy. Whereas the term renewable energy is defined as sustainable, it is considered to be sustainable, it is not considered to be to provide needs in the future. The organization for sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. ; Sustainability science is the study of sustainable development and environmental science. Technologies promote sustainable energy including renewable energy sources, such as hydroelectricity, solar energy, wind energy, power wave, geothermal energy, bioenergy, tidal power and also technologies designed to improve energy efficiency. Costs have decreased immensely throughout the years, and continues to fall. Increasingly, effective government policies support investor confidence and these markets are expanding. Considerable progress is being made in the energy transition from fossil fuels to ecologically sustainable systems, to the point where many studies support 100% renewable energy. such as hydroelectricity, solar energy, wind energy, power wave, geothermal energy, bioenergy, tidal power and also technologies designed to improve energy efficiency.

Energy efficiency and renewable energy are two pillars of sustainable energy. In the context of sustainable development, there are three pillars, ecology, economy and society. Some ways in which sustainable energy can be extracted, generated, and / or consumed without any significant negative impact to the environment. The planet has a natural ability to recover which means that it can not be Green power is a subset of renewable energy and represents the highest environmental benefits. The US Environmental Protection Agency defines green power as electricity produced from solar, wind, geothermal, biogas, biomass and low-impact small hydroelectric sources. Customers often buy green power for environmental benefits and their greenhouse gas reduction benefits.

Renewable energy technologies are essential contributors to sustainable energy sources, and provides opportunities for reducing greenhouse gases. The International Energy Agency states that: First- and second-generation technologies have entered the markets, and third-generation technologies heavily depend on long-term research and development commitments, where the public sector has a role to play. Various Cost-benefit analysis work by a disparate array of experts and agencies has been conducted in the world. With the topic being one of considerable controversy, particularly on the role of nuclear energy.

Among the sources of renewable energy, hydroelectric plants have the advantages of being long-lived-many existing plants have operated for more than 100 years. Also, hydroelectric plants are clean and have few emissions. Large scale hydroelectric plants include: dislocation of people living where the reservoirs are projected, and release of significant amounts of carbon dioxide during construction and flooding of the reservoir. However, it has been found that local, and recent hydropower turbine innovations are enabling efficient development of low-impact run-of-the-river hydroelectricity projects. Generally speaking, hydroelectric plants produce much lower life-cycle emissions than other types of generation. Hydroelectric power, which underwent extensive development during the growth of electrification in the 19th and 20th centuries, is experiencing resurgence of development in the 21st century. The areas of greatest hydroelectric growth are the booming economies of Asia. China is the development leader; However, other Asian nations are installing hydropower at a rapid pace. This growth is driven by much higher energy costs-especially for imported energy-and widespread desires for more domestically produced, clean, renewable, and economic generation. Geothermal power plants can operate over a period of 24 hours, providing basic-load capacity, and the world’s largest potential for geothermal power generation is estimated at 85 GW over the next 30 years. However, geothermal power is only available in limited areas of the world, including the United States, Central America, East Africa, Iceland, Indonesia, and the Philippines. The costs of geothermal energy have dropped substantially from the systems built in the 1970s. Geothermal heat generation can be competitive in many countries producing geothermal power, or in other regions where the resource is of a lower temperature. Enhanced geothermal system (EGS) technology does not require natural convective hydrothermal resources, so it can be used in areas that have been previously adopted for geothermal power, if the resource is very large. EGS is currently under research at the US Department of Energy. Biomass briquettes are being used in the developing world as an alternative to charcoal. The technique involves the conversion of almost any plant into briquettes that have 70% the calorific value of charcoal. There are relatively few examples of large-scale briquette production. One exception is in North Kivu, in eastern Democratic Republic of Congo, where forest clearance is considered to be the greatest threat to mountain gorilla habitat. The staff of Virunga National Park have successfully trained and helped over 3500 people to produce biomass briquettes, replacing existing charcoal produced illegally inside the national park, and creating significant employment for people living in extreme poverty in conflict-affected areas. In Europe in the 19th century, there were about 200,000 windmills, slightly more than the modern wind turbines of the 21st century. They were mainly used to grind grain and to pump water. The age of coal powered steam engines.

Solar heating systems are a well-known second-generation technology and generally consist of solar thermal collectors, a fluid system to move the heat from the collector to its point of use, and a reservoir or tank for heat storage and subsequent use. The system can be used to heat domestic hot water, swimming pool water, or for space heating. The heat can also be used for industrial applications or as an energy input for other uses such as cooling equipment. In many climates, a solar heating system can provide a very high percentage (20 to 80%) of domestic hot water energy. Energy received from the earth by the earth is that of electromagnetic radiation. Light ranges of visible, infrared, ultraviolet, x-rays, and radio waves received by the earth through solar energy. The highest power of radiation comes from visible light. Solar power is complicated to change in the seasons and from day to night. Cloud cover can be added to the consequences of solar energy, and it is absorbed and dispersed by the earth’s atmosphere. In the 1980s and early 1990s, the most photovoltaic modules provided remote-area power supply, but from around 1995, industry efforts have focused more on developing integrated photovoltaic power plants for grid connected applications. Currently the largest photovoltaic power plant in North America is the Nellis Solar Power Plant (15 MW). There was a proposal for a solar power station in Victoria, Australia, which would be the world’s largest PV power station, at 154 MW. Other large photovoltaic power stations include the Girassol solar power plant (62 MW), and the Waldpolenz Solar Park (40 MW). Some of the second-generation renewables, such as wind power, have high potential and have already achieved relatively low production costs. At the end of 2008, global wind farm capacity was 120.791 megawatts (MW), representing an increase of 28.8 percent during the year, and wind power output of 1.3% of global electricity consumption. Wind power accounts for approximately 20% of electricity in Denmark, 9% in Spain, and 7% in Germany. However, it may be difficult to wind turbines in some areas for aesthetic or environmental reasons, and it may be difficult to integrate into some grids. Solar thermal power stations have been successfully operating in California commercially since the late 1980s, including the largest solar power plant of any kind, the 350 MW Solar Energy Generating Systems. Nevada Solar One is another 64MW plant which has recently opened. Other parabolic trough power plants are 50MW plants in Spain, and 100MW plants in Israel. Solar and wind are Intermittent energy sources that supply electricity 10-40% of the time. To compensate for this characteristic, it is common to produce with existing hydroelectricity or natural gas generation. In regions where this is not available, wind and solar can be significantly increased. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18 percent of the country’s automotive fuel. As a result of this, together with the exploitation of domestic deep water sources, Brazil, which has had a large share of the petroleum needed for domestic consumption, recently achieved complete self-sufficiency in oil. Most cars on the road today in the US can run on blends of up to 10% ethanol, and motor vehicles manufacturers produce products designed to run on much higher ethanol blends. Ford, DaimlerChrysler, and GM are among the companies that sell “flexible-fuel” cars, trucks, and minivans that can use gasoline and ethanol blends ranging from pure gasoline up to 85% ethanol (E85). By mid-2006, there were approximately six million E85-compatible vehicles on US

Bio-fuels can be defined as “renewable,” yet may be “sustainable,” due to soil degradation. As of 2012, 40% of American corn production goes to ethanol. Ethanol takes up a large percentage of “Clean Energy Use” when in fact, it is still debatable and should be considered as a “Clean Energy.” According to the International Energy Agency, new bioenergy (biofuel) technologies being developed today, particularly cellulosic ethanol biorefineries, could allow biofuels to play a much larger role in the future than previously thought. Cellulosic ethanol can be made from plant matter of primarily cellulose fibers which form the stems and branches of most plants. Crop residues (such as corn stalks, wheat straw and rice straw), wood waste and municipal solid waste are potential sources of cellulosic biomass. Dedicated energy crops, such as switchgrass, are also promising cellulose sources that can be sustainably produced in many regions of the United States. In terms of ocean energy, another third-generation technology, Portugal has the world’s first commercial wave farm, the Wave Aguçadora Wave, under construction in 2007. The Pelamis P-750 machines generating 2.25 MW. and costs are put at 8.5 million euro. Subject to successful operation, a further 70 million euro is likely to be invested before 2009 on a further 28 machines to generate 525 MW. Funding for a wave farm in Scotland was announced in February, 2007 by the Scottish Executive, at a cost of over 4 million pounds, as part of a £ 13 million in Scotland. The farm will be the world’s largest with a capacity of 3 MW generated by Pelamis furnace machines. (see also Wave farm). In 2007, the world’s largest sales force was installed in the Narrows of Strangford Lough in Ireland. The 1.2 MW underwater tidal electricity generator takes advantage of the fast tidal flow in the lough which can be up to 4m / s. Although the generator is powerful enough to power up to a thousand homes, the turbine has a minimal environmental impact, and it is almost completely submerged, and the rotors turn slowly that they pose no danger to wildlife. Solar power panels that use nanotechnology, which can create circuits out of individual silicon molecules, may cost as much as traditional photovoltaic cells, depending on executives and investors involved in developing products. Nanosolar has secured more than $ 100 million from investors to build a nanotechnology factory for thin-film solar panels. The company has a production capacity of 430 megawatts peak power of solar cells per year. Commercial production started and first panels have been shipped to customers in late 2007. National and regional research projects are developing nanotechnology-based systems that use solar energy to split water into hydrogen fuel. and a proposal has been made for a Global Artificial Photosynthesis Project In 2011, researchers at the Massachusetts Institute of Technology (MIT) developed what they are calling an “Artificial Leaf,” which is capable of splitting water into hydrogen and oxygen directly from solar power when dropped into a glass of water. One side of the “Artificial Leaf” produces bubbles of hydrogen, while the other side produces bubbles of oxygen. Most current solar power plants are made from an array of similar units where each unit is continuously adjusted, eg, with some step motors, so that the light converter stays in focus of the sun light. The cost of focusing on such high-power solar panels, Stirling engine, etc. can be dramatically decreased with a simple and efficient rope mechanics. In this technique many units are connected with a network of lenses that are able to keep pace with each other. Japan and China have national programs at commercial scale Space-Based Solar Power (SBSP). The China Academy of Space Technology (CAST) won the 2015 International SunSat Design Competition with this video of their Multi-Rotary Joint design. Proponents of SBSP claim that Space-Based Solar Power would be clean, constant, and global, and could scale to meet all planetary energy demand. A recent multi-agency industry proposal (echoing the 2008 Pentagon recommendation) won the SECDEF / SECSTATE / USAID Director D3 (Diplomacy, Development, Defense) Innovation Challenge.

Heat pumps and thermal energy storage are classes of technologies that can enable the use of renewable energy sources that would otherwise be inaccessible due to a temperature that is too low for use. The use of water in the form of a water source, such as seawater, lake water, the ground, the air, or waste heat from a process). Thermal storage technologies allow heat or cold to be stored for periods of time or time to interseasonal, and can involve storage of sensitive energy (ie by changing the temperature of a medium) or latent energy (ie through phase changes of a medium, such between water and slush or ice). Short-term thermal storages can be used for peak-shaving in district heating or electrical distribution systems. The use of natural energy (eg collected via solar-thermal collectors, or dry cooling towers used to collect winter’s cold), waste energy (eg HVAC equipment, industrial processes or power plants), gold surplus energy (eg as seasonally from hydropower projects or intermittently from wind farms). The Drake Landing Solar Community (Alberta, Canada) is illustrative. boronhole thermal energy storage allows the community to get 97% of its annual-round heat from solar collectors on the garage roofs, which is most of the heat collected in summer. Types of storages for sensitive energy include insulated tanks, borehole clusters in substrates ranging from gravel to bedrock, deep aquifers, or shallow lined pits that are insulated on top. Some types of storage are capable of storing heat or cold between opposing seasons (particularly if very large), and some storage applications require inclusion of a heat pump. These are called phase-change materials (PCMs). and some storage applications require inclusion of a heat pump. These are called phase-change materials (PCMs). and some storage applications require inclusion of a heat pump. These are called phase-change materials (PCMs).

Moving towards energy sustainability is required, and reducing the amount of energy required is essential. Opportunities for improvement of the supply side of the energy supply and the supply side. Renewable energy and energy efficiency are sometimes said to be “twin pillars” of sustainable energy policy. Both resources must be developed in order to stabilize and reduce carbon dioxide emissions. Efficiency slows down energy demand growth so rising clean energy can make deep cuts in fossil fuel use. If energy use grows too fast, renewable energy development will chase a receding target. A recent historical analysis has shown that the rate of growth is higher than that of the growth rate of energy demand. As a result, despite energy efficiency gains, total energy use and related carbon emissions have continued to increase. Thus, given the thermodynamic and practical limits of energy efficiency improvements, slowing the growth in energy demand is essential. However, unless clean energy supplies come online, slowing demand growth will only begin to reduce total emissions; The content of energy sources is also needed. Any serious vision of a sustainable energy economy requires commitments to both renewables and efficiency. Renewable energy (and energy efficiency) are more likely to be promoted by governments and environmentalists. The increased levels of investment and the fact that they are more likely to be sustainable. An example of this would be the Alliance to Save Energy’s Project with Stahl Consolidated Manufacturing, (Huntsville, Ala., USA) (StahlCon 7), a patented generator shaft designed to reduce emissions within existing power generating systems, 2007. Climate change concerns combined with high and rising rates of growth in the sustainable energy industries, according to a trend analysis from the United Nations Environment Program. According to UNEP, total investment in sustainable energy in 2007 was higher than previous levels, with $ 148 billion of new money raised in 2007, an increase of 60% over 2006. Total financial transactions in sustainable energy, including acquisition activity, was $ 204 billion. Investment flows in 2007 broadened and diversified, making the whole picture one of greater breadth and depth of sustainable energy use. The mainstream capital markets are “now fully receptive to sustainable energy companies, supported by a surge in funds destined for clean energy investment”.

Smart grid refers to the 21st century, using computer-based remote control and automation. These systems are made possible by two-way communication technology and computer processing that has been used for decades in other industries. They are beginning to be used on electricity networks, from power plants and wind farms to the consumers of electricity in homes and businesses. They offer many benefits to utilities and consumers-mostly seen in big improvements in energy efficiency on the electricity grid and in the energy users’ homes and offices.

Green energy includes natural energetic processes that can be harnessed with little pollution. Green power is electricity generated from renewable energy sources. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar energy, biomass power, tidal power, wave power, and some forms of nuclear power , such as an Integral Fast Reactor, and therefore belong to the “Green Energy” category). Some definitions may also be derived from the incineration of waste. Some people, including Greenpeace founder and first member Patrick Moore, George Monbiot, Bill Gates and James Lovelock. Others, including Greenpeace’s Phil Radford disagree, claiming that the problems associated with radioactive waste and the risk of nuclear accidents (such as the Chernobyl disaster) poses an unacceptable risk to the environment and to humanity. However, newer nuclear reactor designs are capable of being used in a manner that is more likely to be dangerous than a nuclear reactor. These designs have yet to be commercialized. (See: Molten Salt Reactor) Some of the reasons for this is that it is a commendable effort in the world of increasing energy consumption, it must be accompanied by a cultural change that encourages the decrease of the world’s appetite for energy. In several countries with common carrier arrangements, electricity retailing arrangements make it possible for consumers to purchase green electricity from their utility or a green power provider. When energy is purchased from the electricity network, the power reaching the consumer will not necessarily be generated from green energy sources. The local utility company, electric company, or state power pool can be generated from fossil fuel, nuclear or renewable energy sources. In many countries, green energy is a contributor to electricity, contributing 2 to 5% to the overall pool. In some US states, local governments have formed regional power purchasing pools using Community Choice Aggregation and Solar Bonds to achieve a 51% renewable mix or higher, such as in the City of San Francisco. By participating in a green energy program can be used to increase energy consumption. They are also making a statement to policy makers that they are willing to pay a premium price to support renewable energy. Green energy consumers are obligated to increase the amount of green energy they purchase from the pool, or directly fund the green energy through a green power provider. If insufficient green energy sources are available, the utility must develop new ones or a third party energy supplier. HOWEVER, There is no way in the world or the green market is “green” or otherwise. In some countries such as the Netherlands, electricity companies guarantee to buy an equal amount of ‘green power’ as they are used by their green power customers. The Dutch government exempts green power from pollution taxes, which means green power is hardly any more expensive than other power. A more recent concept for improving our electrical grid is to beam microwaves from Earth-orbiting satellites or the moon to directly when and where there is demand. In this system, the receivers would be “broad, translucent tent-like structures that would receive microwaves and converts to electricity”. NASA said in 2000 that the technology is worth pursuing but it is still going strong.

Those who are satisfied with the third-party grid approach to green energy through the power grid can install their own locally based renewable energy system. Renewable energy electrical systems from solar to local wind power in some cases, are some of the many types of renewable energy systems available locally. And their dwelling through renewable energy, geothermal heat pump systems that tap the constant temperature of the earth, which is around 7 to 15 degrees Celsius a few feet underground and increases dramatically at greater depths, are an option natural gas and petroleum-fueled heat approaches. Also, in geographic locations where the Earth’s Crust is especially thin, or near volcanoes (where is the case in Iceland) there exists the potential to generate more electricity than would be possible at other sites. The advantage of this approach in the United States is that many states offer incentives to offset the cost of installing a renewable energy system. In California, Massachusetts and several other US states, Community Choice Aggregation has been established by the City of New Brunswick. Individuals are usually assured that they are using electricity from a source of energy. Once the system is paid for,

Renewable energy, after its generation, needs to be stored in a vehicle. Also, to provide electricity grid electricity, energy storage is required for renewable energy. Energy generation and consumption systems are usually stand-alone power systems. Some examples are: Renewable energy power plants provide a steady flow of energy. For example, hydropower seedlings, ocean thermal plants, osmotic power plants, and other sources of power at any given moment (even at night, windstill moments, etc.). At present however, the number of steady-flow renewable energy plants are still too small to meet the demands of the day. Besides the greening of fossil fuel and nuclear power plants, another option is the distribution and immediate use of power from your renewable sources. In this set-up is not necessary. For example, TREC has proposed to distribute solar power from the Sahara to Europe. Europe can distribute wind and ocean power to the Sahara and other countries. In this way, power is produced at any given point in the world, or at any point in the world. This option is probably not possible in the short-term, Fossil fuel and nuclear power are still the main sources of energy on the net electricity hands and they will not be possible overnight. Several large-scale energy storage suggestions for the grid have been done. Worldwide there is over 100 GW of Pumped-storage hydroelectricity. This improves the efficiency and decreases energy losses, but it is a very expensive solution. Some costs could be reduced by making use of the energy storage equipment of the consumer and not the state. An example is batteries in electric cars that would double as an energy buffer for electricity grid. However, besides the cost, a setting such a system would still be very difficult. Also, energy storage apparatus’ batteries are also built with materials that pose a threat to the environment (eg Lithium). The combined production of batteries for such a large part of the population would still have environmental concerns. Besides batteries, however, it is necessary to use less polluting energy carriers (eg compressed air tanks and flywheel energy storage).

 

Directive 2004/8 / EC of the European Parliament and of the Council of Europe on the protection of the environment and the protection of the environment. . European environmental NGOs have launched an ecolabel for green power. The ecolabel is called EKOenergy. It sets criteria for sustainability, additionality, consumer information and tracking. Only part of electricity produced by renewables fulfills the EKOenergy criteria. A [[Green Energy in the United Kingdom # The Green Energy Supply Certification Scheme | Green Energy Supply Certification Scheme]] was launched in the United Kingdom in February 2010. This implements the Energy Regulator, Ofgem, and sets requirements for transparency,

The United States Department of Energy (DOE), the Environmental Protection Agency (EPA), and the Center for Resource Solutions (CRS) recognize the renewable energy and renewable energy sources. Renewable Energy Certificates (RECs) is the most popular way to buy renewable energy by NREL. According to a Natural Marketing Institute (NMI) survey 55 percent of American consumers want to increase their use of renewable energy. DOE selected six companies for its 2007 Green Power Supplier Awards, including Constellation NewEnergy; 3Degrees; Sterling Planet; SunEdison; Pacific Power and Rocky Mountain Power; and Silicon Valley Power. The combined green power provided by those six winners equals more than 5 billion kilowatt-hours per year, which is enough to power nearly 465,000 average US households. In 2014, Arcadia Power made available to all 50 states, allowing consumers to use “100% green power” as defined by the EPA’s Green Power Partnership. The US Environmental Protection Agency (USEPA) Green Power Partnership is a voluntary program that supports the organization of renewable energy by providing technical advice, technical support, tools and resources. This can help organizations, reduce carbon footprint, and communicate its leadership to key stakeholders. Throughout the country, more than half of all US electricity customers now have an option to purchase some type of green power product from a retail electricity provider. Roughly one-quarter of the nation’s utilities, and voluntary sales of renewable energy in the United States totaled more than 12 billion kilowatt-hours in 2006, a 40% increase over the previous year. In the United States, one of the main problems with the electricity grid is the current electricity supplier. This infrastructure has higher emissions, higher energy costs, and power quality issues. An additional $ 450 billion will be invested to expand this system over the next 20 years to meet increasing demand. In addition, This centralized system is now being further extended with the incorporation of renewable energies such as wind, solar, and geothermal energies. Renewable resources, where they are required, where there is a lower energy demand. The current infrastructure would make transporting this energy to high demand areas, such as urban centers, highly inefficient and in some cases impossible. In addition, despite the amount of renewable energy produced or the economic viability of such technologies only about 20 percent will be able to be incorporated into the grid. To have a more sustainable energy profile, the United States should be accommodating to the electricity grid that will accommodate a mixed fuel economy. Several initiatives are being proposed to mitigate distribution problems. First and foremost, the most effective way to reduce USA’s emissions and slow global warming is through conservation efforts. Opponents of the current US electrical grid also advocated for decentralizing the grid. This system would increase efficiency by reducing the amount of energy lost in transmission. It would also be economically viable as it would reduce the amount of money that will be constructed in the future to keep up with demand. Merging heat and power in this system would create added benefits and help to increase its efficiency by up to 80-90%. This is a significant increase in the current fossil fuel plants which has an efficiency of 34%. Opponents of the current US electrical grid also advocated for decentralizing the grid.

There are numerous organizations within the academic, federal, and commercial sectors leading large scale advanced research in the field of sustainable energy. This research spans several areas of focus in the sustainable energy spectrum. Most of the research is aimed at improving efficiency and increasing overall energy yields. Multiple federally supported research organizations have focused on sustainable energy in recent years. The National Renewable Energy Laboratory (NREL) and the National Renewable Energy Laboratory (NREL), both of which are funded by the United States Department of Energy and supported by various corporate partners. Sandia has a total budget of $ 2.4 trillion while NREL has a budget of $ 375 million. Scientific production towards sustainable energy systems is rising exponentially,

The primary obstacle that is preventing the large scale implementation of solar energy is the inefficiency of current solar technology. Currently, photovoltaic (PV) panels only have the ability to convert around 24% of the sunlight that hits them into electricity. At this rate, solar energy still has many challenges for widespread implementation. Both Sandia National Laboratories and the National Renewable Energy Laboratory (NREL), have heavily funded solar research programs. The NREL has a budget of around $ 75 million and develops research projects in the areas of photovoltaic (PV) technology, solar thermal energy, and solar radiation. The budget for Sandia ‘s solar division is unknown, however it accounts for a significant percentage of the $ 2.4 billion budget. Several academic programs have focused on solar research in recent years. The Solar Energy Research Center (SERC) at the University of North Carolina (UNC) has the sole purpose of developing effective solar technology. In 2008, researchers at the Massachusetts Institute of Technology (MIT) developed a method to store solar energy using hydrogen fuel from water. Such research is targeted at the obstacle that the development of solar energy is not shining. In February 2012, North Carolina-based Semprius Inc., a solar development company backed by German corporation Siemens, announced that they had developed the world’s most efficient solar panel. The company claims that the prototype converts 33.9% of the sunlight that hits it to electricity, more than double the previous high-end conversion rate. Major projects on artificial photosynthesis or solar fuels are also under way in many developed nations.

Space-Based Solar Power Satellites seek to overcome the problems of civilization-scale power that is clean, constant, and global. Japan and China have active national programs for commercial scale Space-Based Solar Power (SBSP), and both nation’s hope and orbit demonstrations in the 2030s. The China Academy of Space Technology (CAST) won the 2015 International SunSat Design Competition with this video of their Multi-Rotary Joint design. Proponents of SBSP claim that Space-Based Solar Power would be clean, constant, and global, and could scale to meet all planetary energy demand. A recent multi-agency industry proposal (echoing the 2008 Pentagon recommendation) won the SECDEF / SECSTATE / USAID Director D3 (Diplomacy, Development, Defense) Innovation Challenge with the following pitch and vision video. Northrop Grumman is funding CALTECH with $ 17.5 million for an ultra lightweight design. Keith Henson recently posted a video of a “bootstrapping” approach.

Wind energy research dates back several decades to the 1970s when NASA developed an analytical model to predict wind turbine power generation during high winds. Today, both Sandia National Laboratories and National Renewable Energy Laboratory have programs dedicated to wind research. Sandia’s laboratory focuses on the advancement of materials, aerodynamics, and sensors. The NREL wind projects are centered on improving energy production, reducing their capital costs, and making them more energy efficient. The Field Laboratory for Optimized Wind Energy (FLOWE) at Caltech was established in the United States. The president of Sky WindPower Corporation thinks that wind turbines will be able to produce electricity at a cent / kWh at a fractional of the cost. A wind farm is a group of wind turbines in the same location used to produce electric power. A large wind farm may consist of several individual wind turbines, and may be used for other purposes. A wind farm may also be located offshore. Many of the largest operational onshore wind farms are located in the USA and China. The Gansu Wind Farm in China has over 5,000 MW installed with a goal of 20,000 MW by 2020. China has several other “wind power bases” of similar size. The Alta Wind Energy Center in California is the largest onshore wind farm in China, with a capacity of 1020 MW of power. Europe leads with 66 GW, about 66 percent of the total globally, with Denmark in the lead to the countries installed per capita capacity. As of February 2012, the Walney Wind Farm in United Kingdom is the largest offshore wind farm in the world at 367 MW, followed by Thanet Wind Farm (300 MW), also in the UK.There are many large wind farms under construction and these include BARD Offshore 1 (400MW), Clyde Wind Farm (350MW), Greater Gabbard wind farm (500MW), Lincs Wind Farm (270MW), London Array (1000MW), Lower Snake River Wind Project (343MW) , Macarthur Wind Farm (420 MW), Shepherds Flat Wind Farm (845 MW), and Sheringham Shoal (317 MW). Wind power has expanded quickly,

Biomass is a biological material derived from living, or recently living organisms. It is often referred to as lignocellulosic biomass. As an energy source, biomass can be used directly by combustion to produce heat, or indirectly after conversion to various forms of biofuel. Biomass conversion can be achieved by various methods which are broadly classified into: thermal, chemical, and biochemical methods. Wood remains the largest biomass energy source today; Examples include forest residues – such as dead trees, branches and tree stumps -, yard clippings, wood chips and even municipal solid waste. In the second sense, biomass includes plant or animal that can be converted into fibers or other industrial chemicals, including biofuels. Industrial biomass can be grown from numerous types of plants, including miscanthus, switchgrass, hemp, corn, poplar, willow, sorghum, sugarcane, bamboo, and a variety of tree species, ranging from eucalyptus to oil palm (palm oil). Biomass, biogas and biofuels are produced by the environment. Pollutants such as sulphurous oxides (SO x), nitrous oxides (NO x), and particulate matter (PM) are produced from this combustion; the World Health Organization estimates that 7 million premature deaths are caused by air pollution.

As the primary source of biofuel in North America, many organizations are conducting research in the area of ​​ethanol production. On the Federal level, the USDA conducts a large amount of research regarding ethanol production in the United States. Much of this research is focused on the effect of ethanol production on domestic food markets. The National Renewable Energy Laboratory has conducted various ethanol research projects, mainly in the area of ​​cellulosic ethanol. Cellulosic ethanol has many benefits over traditional corn-based ethanol. It does not take away or grease, or non-edible parts of plants. Moreover, some studies have shown cellulosic ethanol to be more cost effective and economically sustainable than corn-based ethanol. Even if we used all the corn crop we had in the United States and converted it into ethanol it would only produce enough fuel to serve 13 percent of the United States total gasoline consumption. Sandia National Laboratories conducts in-house cellulosic ethanol research and is also a member of the Joint BioEnergy Institute (JBEI), a research institute founded by the United States Department of Energy with the goal of developing cellulosic biofuels.

From 1978 to 1996, the National Renewable Energy Laboratory experimented with the production of algae fuel in the “Aquatic Species Program.” A self-published article by Michael Briggs, at the University of New Hampshire Biofuels Group, offers estimates for the realistic replacement of all motor vehicles with biofuels by utilizing a natural gas content greater than 50%, which Briggs suggests grown on algae ponds at wastewater treatment plants. This oil-rich algae can then be extracted from the system and processed into biofuels, with the dried remainder further reprocessed to create ethanol. The production of algae has not yet been undertaken, but feasibility studies have been conducted at the above yield estimate. During the biofuel production process, the oxygen dioxide is in the air and turns into oxygen through photosynthesis. In addition to its high-yield projections, algaculture- unlike food crop-based biofuels – does not entail a decrease in food production, since it requires neither farmland nor fresh water. Many companies are pursuing algae bio-reactors for various purposes, including scaling up biofuels production to commercial levels. Jatropha curcas, a poisonous shrub-like, which is a viable source of biofuels feedstock oil. Much of this research focuses on improving the overall performance of Jatropha through advancements in genetics, soil science, and horticultural practices. SG Biofuels, a San Diego-based Jatropha developer, has used molecular breeding and biotechnology to produce elite hybrid seeds of Jatropha. The Center for Sustainable Energy Farming (CfSEF) is a Los Angeles-based non-profit research organization dedicated to Jatropha research in the areas of plant science, agronomy, and horticulture. Successful exploration of these disciplines is projected to increase Jatropha farm production yields by 200-300% in the next ten years.

Geothermal energy is produced by tapping into the thermal energy and stored in the earth. It arises from the radioactive decay of an isotope of potassium and other elements found in the Earth’s crust. Geothermal energy can be obtained by drilling into the ground, and then it is carried by a heat-transfer fluid (eg water, brine or steam). Geothermal systems that are mainly dominated by water and power generation. Within these liquid-dominated systems, there is the possibility of subsidence and contamination of groundwater resources. Therefore, protection of groundwater resources is necessary in these systems. This means that careful reservoir production and engineering is necessary in liquid-dominated geothermal reservoir systems. Geothermal energy is considered sustainable because it is constantly replenished. However, the science of geothermal energy is still young and developing economic viability. Several entities, such as the National Renewable Energy Laboratory and Sandia National Laboratories, are conducting research towards the goal of establishing a science-based geothermal energy. The International Center for Geothermal Research (IGC), a German geoscience research organization, is widely focused on geothermal energy development research. the science of geothermal energy is still young and developing economic viability.

Over $ 1 trillion of federal funds in the United States. Both the National Renewable Energy Laboratory and Sandia National Laboratories have dedicated departments to hydrogen research. Hydrogen is useful for energy storage and for use in airplanes, but it is not practical for automobile use, it is not very efficient, compared to using a battery.

There are two sources of nuclear power. Fission is used in all nuclear power plants. Fusion is the reaction that exists in stars, including the sun, and remains impractical for use on Earth. Nuclear power is controversial and politically and scientifically related to the subject of radioactive waste disposal, safety, the risks of a severe accident, and the technical and economic problems of dismantling of old power plants. Thorium is a fissionable material used in thorium-based nuclear power. The thorium fuel cycle claims several potential advantages over a uranium fuel cycle, including greater abundance, superior physical and nuclear properties, better resistance to nuclear weapons proliferation and reduced plutonium and actinide production. Therefore,

2010 was a record year for green energy investments. According to a report from Bloomberg New Energy Finance, nearly US $ 243 billion was invested in wind farms, solar power, electric cars, and other alternative technologies worldwide, representing a 30 percent increase from 2009 and nearly five times the money invested in 2004. China had $ 51.1 billion investment in clean energy projects in 2010, by far the largest figure for any country. Within emerging economies, Brazil comes second to China in terms of clean energy investments. Supported by strong energy policies, Brazil has one of the world’s highest biomass and small-hydro power capacities and is poised for significant growth in wind energy. The cumulative investment potential in Brazil from 2010 to 2020 is projected to be $ 67 billion. India is another rising clean energy leader. While India ranked the 10th in private clean energy among G-20 members in 2009, over the next 10 years it is expected to rise to the third position, with 2020. It is clear that the center of growth has started to shift to the developing world. Around the world many sub-national governments – regions, states and provinces – have aggressively pursued sustainable energy investments. In the United States, California’s leadership in renewable energy was recognized by The Climate Group when it awarded the Governor Arnold Schwarzenegger’s inaugural award for international climate leadership in Copenhagen in 2009. In Australia, the state of South Australia – under the leadership of former Premier Mike Rann – 26% of its electricity generation by the end of 2011, edging out coal fired generation for the first time. South Australia also has had the highest take-up per capita of household solar panels in Australia following the Rann Government’s introduction to solar photovoltaic and public education projects involving the installation of solar photovoltaic facilities on the roofs of public buildings prominent, including the parliament , museum, airport and Adelaide Showgrounds pavilion and schools. Rann, Australia’s first climate change minister, passed legislation in 2006 setting targets for renewable energy and emissions cuts, the first legislation in Australia to do so. Also,
