There is a renewable energy debate on the constraints and opportunities associated with the use of renewable energy. Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent. However, the International Energy Agency has stated that its significance depends on a range of factors, such as the penetration of the renewables concerned. There have been concerns about the visual and other impacts of some wind farms, with local residents either fighting or blocking construction. In the USA, the Massachusetts Cape Wind project has been delayed for many years. However, residents in other areas have been more positive and there are many examples of community wind farm developments. According to a town council, the overwhelming majority of locals believe that the Ardrossan Wind Farm in Scotland has enhanced the area. The market for renewable energy technologies has continued to grow. Climate change concerns, coupled with high oil prices, rising oil, and rising government support, incentives and marketing. New government spending, regulation and policies helped the industry weather the economic crisis. are driving increasing renewable energy legislation, incentives and marketing. New government spending, regulation and policies helped the industry weather the economic crisis. are driving increasing renewable energy legislation, incentives and marketing. New government spending, regulation and policies helped the industry weather the economic crisis.

Renewable energy flows entails natural phenomena such as sunlight, wind, tides, plant growth, and geothermal heat, as the International Energy Agency explains: number of countries.

Variability inherently affects solar energy, as the production of electricity from solar sources depends on the amount of light energy in a given location. Solar output varies throughout the day, with the seasons, with cloud cover and by latitude on the globe. Windblown glass sand in dry climates, protective layers add expenses. These factors are fairly predictable, and some solar thermal systems make use of molten salt to produce energy when the sun is not shining. Wind-generated power is a variable resource, and the amount of electricity produced by a given source of energy, air density, and turbine characteristics (among other factors). If wind speed is too low (less than about 2.5 m / s) and if it is too high (more than about 25 m / s) the turbines will be shut down to avoid damage. While the output of a single turbine is much smaller, it is more likely to be variable. Capacity factors for solar PV are more likely to vary between 10-20% of the rated nameplate capacity. Onshore wind is better at 20-35% and offshore wind is best at 45%. This means that total capacity needs to be achieved in order to achieve an average output for the year. The capacity factor relates to statements about capacity increases. The International Energy Agency says that there is too much attention on the issue of the variability of renewable electricity production. This issue only applies to certain renewable energy technologies, mainly wind power and solar photovoltaics, and to a larger scale of hydroelectricity. The significance of this variable depends on a range of factors that include the market of renewable sources, the nature of the energy sources, and the demand for flexibility. Renewable electricity supply and management of renewable energy in the United States. Several European systems, in the context of an integrated European grid system: In 2011, Intergovernmental Panel on Climate Change, the world’s leading climate scientists selected by the United Nations, said “as infrastructure and energy systems” technologies to meet a majority share of the total energy demand. IPCC scenarios “generally indicate that growth in renewable energy will be widespread around the world”. The IPCC said that they were supportive, and the full complement of renewable energy technologies were deployed, renewable energy supply accounts for almost 80% of the world’s energy use within forty years. Rajendra Pachauri, chairman of the IPCC, said the necessary investment in renewables would be only 1% of global GDP annually. This approach could contain as much as 450 parts per million, which is becoming catastrophic and irreversible. Mark Z. Jacobson says that there is no shortage of renewable energy and a “smart mix” of renewable energy sources can be used to meet the demand for electricity. It can be used in conjunction with a wind turbine, and it can be used in many situations. As physicist Amory Lovins has said: The variability of the sun, wind and so on, go out to be a non-problem if you do several sensible things. One is to diversify your renewables by technology, so that weather conditions are good for one another. Second, they are not so much about the same weather pattern at the same time because they’re in the same place. Third, you are using a standard weather forecasting technique, hydro, and of course. Fourth, you integrate all your resources – supply side and demand side … “The combination of renewable energy and renewable energy. system that has the potential to meet our needs reliably. Integrating ever-higher levels of renewables is being successfully demonstrated in the world: In 2009, eight American and three European authorities, writing in the leading professional engineers, did not find a credible and firm technical limit to the amount of wind energy that can be accommodated by electricity grids “. In Fact, Not one of more than 200 international studies, nor official studies for the eastern and western US regions, nor the International Energy Agency, and in some studies much more. Renewable electricity supply in the 20-50 +% range has been implemented in several European systems, in the context of an integrated European grid system: In 2010, oven German states, totalling 10 million people, relies on wind power for 43-52% of their annual electricity needs. Denmark is not far behind, supplying 22% of its power in 2010 (26% in an average wind year). The Extremadura region of Spain is getting up to 25% of its electricity from solar, while the country meets 16% of its demand from wind. Just during 2005-2010, Portugal vaulted from 17% to 45% renewable electricity. Integration of renewable energy in Germany. Voltage fluctuations have caused problems with sensitive equipment. In one case, Hydro Aluminum plant in Hamburg was forced to shut down when the rolling mill is highly sensitive to the production of such abruptly that the aluminum belts snagged. They hit the machines and destroyed a piece of the mill. The malfunction was caused when the electricity grid weakened for a millisecond. A survey of members of the Association of German Industrial Energy Companies (VIK) revealed that the number of short interruptions to the German electricity grid has grown by 29 percent in the 2009-2012 years. Over the same time period, the number of service providers has grown to 31 percent, and almost half of those failures to production stoppages. Damages have ranged between € 10,000 and euros, according to company information. Minnkota Power Cooperative, the leading US wind utility in 2009, supplied 38% of its retail sales from the wind. Mark A. Delucchi and Mark Z. Renewable energy is a renewable energy source for renewable energy, and they are more likely to be renewable. of fuel. Unlike plutonium for fuel, they are not subject to the volatility of global fuel markets. Renewable power decentralizes electricity supply and so minimizes the need to produce, transport and store hazardous fuels; reliability of power generation is produced by producing power close to the energy consumer. An accidental or intentional outage affects a larger amount of capacity than an outage at a larger power station. The Fukushima I nuclear accidents in Japan have brought new attention to the problem of climate change. These threats to our old energy systems provide a rationale for investing in renewable energy.

Renewable energy technologies are getting cheaper, and the benefits of mass production and market competition. A 2011 IEA report said: “A portfolio of renewable energy technologies is becoming cost-competitive in an emerging broad spectrum of circumstances, in some cases providing The price of PV modules per MW has fallen by 60 percent since the summer of 2008, according to Bloomberg New Energy Finance estimates, putting solar power for the first time on a competitive price. Wind turbine prices have also fallen – by 18 percent per MW in the last two years – reflecting, as with solar, fierce competition in the supply chain. Further improvements in the level of energy, solar energy, and other technologies lie ahead, posing a growing threat to the dominance of fossil fuel generation sources in the next few years. Hydro-electricity and geothermal electricity produced are favored sites. Renewable energy costs, solar photovoltaic (PV), concentrated solar power (CSP) and some biomass technologies. Wind and Solar are able to produce electricity for 20-40% of the year. Renewable energy is also the most economical solution for new grid-connected fossil fuels. As the cost of renewable energy falls, the scope of economically viable applications increases. Renewable technologies are now often the most economic solution for new generation capacity. Where “oil-fired generation is the predominant source power generation (eg on islands, off-grid and some countries)”. Indicative, levelised, economic costs for renewable energy are shown in the table below. As of 2012, renewable energy generation technologies accounted for globally. In 2011, additions included 41 gigawatt (GW) of new wind power capacity, 30 GW of PV, 25 GW of hydro-electricity, 6 GW of biomass, 0.5 GW of CSP, and 0.1 GW of geothermal power. Hydropower provides 16.3% of the world’s electricity. When combined with the other renewables wind, geothermal, solar, biomass and waste: together they make up 21.7% of electricity generation worldwide in 2013.

The “base load” is the minimum level of demand on an electrical grid over a period of time, some variation in demand may be compensated by varying production or electricity trading. The criteria for low-cost power generation are low price, availability and reliability. Over the years as technology has been developed. Hydroelectricity was the first method and was still in a few wet climates like Brazil, Canada, Norway and Iceland. Coal has become the most popular source for the development of the steam turbine and bulk transport, and is standard in the world. Nuclear power is also used in coal, France is predominantly nuclear and uses less than 10% fossil fuel. In the US, The increasing popularity of natural gas is likely to replace coal as the base. There are no countries where the majority of solar power is supplied by solar, biofuels or geothermal, as they are of low price, availability and reliability.

Renewable power technologies can have significant environmental benefits. Unlike coal and natural gas, they have a significant role in reducing greenhouse gas emissions. as discussed in the article Indirect land uses change impacts of biofuels. Both solar and wind have been criticized from an aesthetic point of view. However, methods and opportunities exist to deploy these renewable technologies efficiently and unobtrusively: fixed solar collectors can double barriers along highways, and extensive roadway, lot parking, and roof-top area is currently available; amorphous photovoltaic cells can also be used to produce energy. Advocates of Renewable Energy also argues that current infrastructure is less aesthetically pleasing than alternatives, but is more critical.

In 2015 hydropower generated 16.6% of the world’s total electricity and 70% of all renewable electricity. The major advantage of conventional hydroelectric systems with reservoirs is their ability to produce power for later production on demand. When used in conjunction with intermittent sources like wind and solar, a constant supply of electricity is achieved. Other advantages include longer life than fuel-fired generation, low operating costs, and other uses of the reservoir. In areas without natural water flow, pumped-storage plants provide a constant supply of electricity. Overall, hydroelectric power can be far less expensive than electricity generated from fossil fuels or nuclear energy, and areas with abundant hydroelectric power attract industry. In Canada it’s estimated there are 160, 000 megawatts of undeveloped hydro potential. However, there are some disadvantages associated with hydroelectric power. These include: dislocation if there are people living where the reservoirs are planned, release of significant amounts of carbon dioxide at construction and flooding of the reservoir, disruption of aquatic ecosystems and birdlife, adverse impacts on the river environment, potential risks of sabotage and terrorism , and in rare cases catastrophic failure of the dam wall.

* Economic gains Hydro is a flexible source of electricity since plants can be ramped up and down very quickly to adapt to changing electrical demands. The cost of operating a fossil fuels, natural gas or coal, and no imports are needed. The average cost of electricity is greater than 10 megawatts is 3 to 5 US cents per kilowatt hour. Hydroelectric plants have long economic lives, with some plants still in service after 50-100 years. Operating labor cost is also usually low, as it is small enough to operate on site during normal operation. * ” ‘Industrial use While many hydroelectric projects supply public electricity networks, some are created to serve specific industrial enterprises. Dedicated hydroelectric projects are often built for the aluminum aluminum electrolytic plants, for example. Alcoa Aluminum in Bellingham, Washington, United States for Alumna in the United States for the first time in the world. In Suriname, the Brokopondo Reservoir was constructed to provide electricity for the Alcoa aluminum industry. New Zealand’s Manapouri Power Station was built to supply electricity to aluminum smelters at Tiwai Point. Since they have not fossil fuels, they do not directly produce carbon dioxide or pollutants. While some carbon dioxide is produced during this period, it is a tiny fraction of the operating emissions of fossil fuel-fuel electricity generation. One measurement of greenhouse gas and other external energy sources can be found in the ExternE project by the Paul Scherrer Institute and the University of Stuttgart, which is funded by the European Commission. According to that study, hydroelectricity produces the least amount of greenhouse gases and externality of any energy source. Coming in second place was wind, third was nuclear energy, and fourth was solar photovoltaic. The low greenhouse gas impact of hydroelectricity is found especially in temperate climates. The above study was for local energy in Europe; presumably similar conditions prevail in North America and Northern Asia, which include a regular, natural freeze / thaw cycle (with associated seasonal plant decay and regrowth). Greater greenhouse gas emissions of methane are found in the tropical regions. * Other reservoirs The cost of large dams and reservoirs is justified by some of the benefits. Reservoirs often provide facilities for water sports, and become tourist attractions themselves. In some countries, aquaculture in reservoirs is common. Multi-use dams installed for irrigation support agriculture with a relatively constant water supply. Large reservoirs can control flooding and alleviate droughts, which would otherwise harm people living downstream. The Columbia River Treaty between the US and Canada required that in the 1960s and 1970s, very large tanks were constructed for flood control. In the construction of some hydroelectric plants.

The loss of land is often exacerbated by habitat fragmentation caused by the reservoir. In Europe and North America, environmental concerns have been raised over the past 30 years of construction in the 1990s. Large dams and tanks continue to be built in China, Brazil and India. Reservoirs displace communities A consequence is the need to relocate the people living where the reservoirs are planned. In 2000, the World Commission on Dams estimated that 40-80 million people worldwide. An example is the contentious Three Gorges Dam which displaced 1.24 million residents. In 1954 the river flooded, killing 33,000 people and forcing 18 million people to move to higher ground. Cubic kilometers of water. * Reservoir siltation When water flows it has the ability to transport particles heavier than itself downstream. This may be adversely affected by the reservoir capacity and their power stations, particularly those on rivers or within catchment areas with high siltation. Siltation can fill a reservoir and reduce its capacity to control floods along with additional pressure. Eventually, some reservoirs can become full of sediment and useless or over-top during a flood and fail. * Reservoirs methane generation Some reservoirs in tropical regions. This is a plant in an environment, and a methane form, a greenhouse gas. According to the World Commission on Dams, the reservoir is large compared with the generation capacity (less than 100 watts per square meter of surface area) and greenhouse gas emissions from the reservoir may be higher than those of a conventional oil-fired thermal generation plant. There is a lack of knowledge in the scientific community regarding GHG emissions, producing many diverging positions. To resolve this situation, the International Energy Agency is coordinating an analysis of actual issues. In the boreal reservoirs of Canada and Northern Europe, greenhouse gases are typically only 2% to 8% of any kind of fossil fuel-fuel thermal generation. A new class of underwater logging operation that targets drowned forests can mitigate the effect of forest decay. * Reservoir safety Because large dammed-hydro facilities hold back large volumes of water, a failure due to poor construction, Natural disasters or sabotage can be catastrophic to downriver settlements and infrastructure. During Typhoon Nina in 1975 Banqiao Dam failed in Southern China when more than a year of rain fell within 24 hours. The result flood occurred in the deaths of 26,000 people, and another 145,000 from epidemics. Millions were left homeless. Also, the creation of a dam in Italy, where almost 2000 people died. Smaller dams and micro hydro facilities create less risk, but can still be prevented after decommissioned. For example, the small 1939 Kelly Barnes Dam failed in 1967, causing 39 deaths with the Toccoa Flood, which was decommissioned. * ” ‘ Downstream aquatic ecosystem Hydroelectric projects can be disruptive to surrounding aquatic ecosystems downstream of the plant site. Changes in the amount of the flow of the correlated with the amount of energy produced by a dam. Water exiting a reservoir usually contains very little suspended sediment, which can lead to scouring of rivers and waterbanks. For fish migration a fish ladder may be required. For fish going through a high head turbine is usually fatal. Reservoir water passing through a turbine at the downstream river environment. Downstream changes to the water temperature and other gases. In addition to this, alteration to the amount of water through the dam can also change the composition of gasses in the water downstream. Changes in the amount of discharges to the ground and to the spawning grounds for forcing them to retreat. Even if mating season has passed, any newly hatched fry can be killed off by low water levels in their spawning areas.

Unlike fossil fuel based technologies, solar power does not lead to any harmful emissions during operation, but the production of the panels leads to some amount of pollution. The energy payback time of a power generation system is the time required to generate energy consumption. In 2000 the energy payback time of PV systems was estimated at 8 to 11 years and in these years it was estimated to be 1.5 to 3.5 years for crystalline silicon PV systems and 1-1.5 years for thin film technologies (S. Europe). Another economic measure, closely related to the energy payback time, is the energy returned on energy (EROEI) or energy return on investment (EROI), which is the ratio of electricity generated by the energy required to build and maintain the equipment. (This is not the same as the economic return on investment (ROI), which varies according to local energy prices, subsidies and metering techniques.) With lifetimes of at least 30 years, the EROEI of PV systems are in the range of 10 to 30, thus generating sufficient energy on their lives to reproduce themselves many times (6-31 reproductions). One issue that has been raised is the use of cadmium in cadmium telluride solar cells (CdTe is only used in a few types of PV panels). Cadmium in its metallic form is a substance that has the tendency to accumulate in ecological food chains. The amount of cadmium used in thin-film PV modules is relatively small (5-10 g / m²) and with proper emission control techniques in place the cadmium emissions from module production can be almost zero. Current PV technologies lead to cadmium emissions of 0.3-0.9 microgram / kWh over the whole life cycle. Most of these emissions actually arise through the use of lignite combustion, and lead to much higher emissions of cadmium. Life-cycle cadmium emissions from coal is 3.1 microgram / kWh, lignite 6.2, and natural gas 0.2 microgram / kWh. Note that if produced by photovoltaic panels were used instead of the modules instead of electricity from coal burning, cadmium emissions from coal power use in the manufacturing process could be entirely eliminated. Solar power plants require large amounts of land. According to the Bureau of Land Management, there are 20 proposals to use in total about 180 square miles of public land in California. If they were built, they would total 7,387 megawatts. The requirement for a new energy efficiency strategy for solar energy is one of the most important issues in the world. . Sensitive wildlife impacted by large solar facilities include the desert tortoise, Mohave Ground Squirrel, Mojave fringe-toed lizard, and desert bighorn sheep. In the United States, some of the land in the eastern portion of the Mojave Desert is to be preserved,

Biofuel production has increased in recent years. Some commodities like maize (corn), sugar cane or vegetable oil can be used as food, feed, or to make biofuels. The Food vs. The Food vs. fuel debate is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of food supply. The biofuel and food price is a long-standing, controversial one in the literature. There is disagreement about the significance of the issue, what is it, and what can be done to remedy the situation. This complexity and uncertainty is due to the large number of impacts and feedback loops that can positively or negatively affect the price system. Moreover, the relative strengths of these positive and negative impacts in the short and long term, and involved delayed effects. The academic side of the debate is also blurred by the use of different economic models and competing forms of statistical analysis. According to the International Energy Agency, new biofuels technologies being developed today, particularly cellulosic ethanol, 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. The ethanol and biodiesel production industries also create jobs in plant construction, operations, and maintenance, mostly in rural communities. According to the Renewable Fuels Association, the ethanol industry created almost 154,000 US jobs in 2005 alone, boosting household income by $ 5.7 billion. It also contributed about $ 3.5 billion in local tax revenues, state, and federal levels. Biofuels are different from fossil fuels in the form of carbon emissions, but are similar to fossil fuels in that biofuels contribute to air pollution. Burning produces airborne carbon particles, carbon monoxide and nitrous oxides. The WHO estimates 3.7 million premature deaths worldwide in 2012 due to air pollution.

Mark Diesendorf, formerly Professor of Environmental Science at the University of Technology, Sydney, and Senior Research Scientist with CSIRO, has summarized some of the benefits of onshore wind farms. Studies of birds and offshore wind farms in Europe have found that there are very few bird collisions. Several offshore wind sites in Europe have been used in these areas by seabirds. Improvements in wind turbine design, with a much slower rate of rotation of the blades and a smooth tower base instead of perchable lattice towers, However, smaller wind turbines can be dangerous to flying birds. Birds are severely impacted by fossil fuel energy; examples include birds dying from exposure to oil spills,

There have been concerns about the visual and other impacts of some wind farms, with local residents either fighting or blocking construction. In the USA, the Massachusetts Cape Wind project has been delayed for many years. Elsewhere, there are concerns that some facilities can negatively affect TV and radio reception and Doppler weather radar, as well as produce excessive sound and vibration levels. Potential broadcast-reception solutions include predictive interference modeling and a component of site selection. However, residents in other areas have been more positive and there are many examples of community wind farm developments. According to a town councilor, The overwhelming majority of locals believe that the Ardrossan Wind Farm in Scotland has enhanced the area. A starting point for a better understanding of the community is the public outreach initiatives (eg, surveys, town hall meetings) to clarify the nature of concerns. Community concerns regarding wind power projects have been shown to be more popular than actual fact. In tourist areas, for example, there is a misperception that the siting of wind farms will adversely affect tourism. Yet surveys conducted in tourist areas in Germany, Belgium, and Scotland show that this is simply not the case. Similarly, according to Valentine, concerns over wind noise turbine, shadow flicker, and bird life threats are not supported by actual data. The difficulty is that the general public often does not have access to information necessary to evaluate the pros and cons of wind power developments. However, there are often important ‘qualifications’ around the delivery of infrastructure (ie, providing mitigation of development impacts on local ecology and assets). Media reports tend to emphasize storylines that have popular appeal. Therefore, media coverage often fails to provide the full project information that the public needs to effectively evaluate the merits of a wind project. Moreover, misinformation about wind power may be propagated by fossil fuel and nuclear power special interest groups. Often there is an ideological right wing which tends to dominate, supporting anti-green and anti-climate-science positions. The Australian anti-wind site Stop These Things best explores this approach, describing environmentalists as Greentards. The lesson for planners and policymakers is one of some forms of public opposition. In fact, not only will it be more proactive, but it may also lead to enhanced support. Public perceptions generally improve after wind projects become operational. United Kingdom, Scotland, France, the United States, United States, and Finland have demonstrated that wind farms which are properly planned and managed. Wind energy projects, which have been well-planned to reduce social and environmental problems, have been shown to be positively influential. Support is enhanced when community members are offered investment opportunities and involvement in the wind power development. Many wind power companies with local communities to reduce environmental and other related issues. Appropriate government consultation, planning and approval. Some people may still be interested in the Australian Institute, their concerns should be weighed against the need to address the dangers of climate change. In other cases there is direct community ownership of wind farm projects. In Germany, millions of people are invested in the world of business, and are the fastest growing businesses in the world. Wind power has gained very high social acceptance in Germany. Surveys of public attitudes across Europe and in many other countries. In America, wind projects are reported to boost local tax bases, helping to pay for schools, roads and hospitals. Wind projects also revitalizes the economy of rural communities by providing steady income to farmers and other landowners. The Intrepid Wind Farm, in Iowa, is an example of a small farm where the environmental impact of the project has been minimized through consultation and co-operation. So, when they start with the Intrepid site, they are working with a number of states and national environmental groups, using the Iowa State Department of Natural Resources, Nature Conservancy, Iowa State University, the US Fish and Wildlife Service, the Iowa Natural Heritage Foundation, and the Iowa Chapter of the Sierra Club, MidAmerican created a statewide of areas in the region that contained specific bird populations or habitats. Those areas were then avoided as site planning got underway in earnest. In addition, the US Army also worked in conjunction with the Army Corp of Engineers, to secure the area. Regular inspections are also carried out in the same way as in other countries. MidAmerican also worked in conjunction with the Army Corp Engineers, to secure the area. Regular inspections are also carried out in the same way as in other countries. MidAmerican also worked in conjunction with the Army Corp Engineers, to secure the area.

Even though a renewable energy infrastructure, like hydroelectric dams, will not last forever, and should be removed and replaced at some point. Events like the shifting of riverbeds, or changing weather patterns could potentially alter or even halt the function of hydroelectric dams, lowering the amount of time they are available to generate electricity. A capacity container may also be affected by silting which may not be cost-effective to remove. Wind Turbines of the United States. Some have claimed that geothermal energy is a renewable source of energy. If depletion does occur, the temperature can regenerate if given a long period of non-use. The government of Iceland states: “It should be stressed that the geothermal resource is not strictly renewable in the same sense as the hydro resource.” It estimates that Iceland’s geothermal energy could provide 1700 MW for over 100 years, compared to the current production of 140 MW. Radioactive elements in the Earth’s crust in a constant decay, replenishing the heat. The International Energy Agency classified geothermal power as renewable. Geothermal power in Iceland is developed in a stepwise way to ensure that it is sustainable instead of excessive, which would deplete the resource.

The US electric power industry is now connected to large, central power stations, including coal, natural gas, nuclear, and hydropower plants that together generate more than 95% of the nation’s electricity. Over the next few decades can be used to diversify the nation’s bulk power supply. In 2016 renewable hydro, solar, wind, geothermal and biomass produced 39% of California’s electricity. Although most of today’s electricity comes from large, central-station power plants, new technologies offer a range of options for generating electricity, where it is needed, saving on the cost of transmitting and distributing power and improving the efficiency and reliability of the system. Improving energy efficiency represents the most effective and efficient way to reduce oil dependence, improve energy security, and reduce the health and environmental impact of the energy system. By reducing the total energy requirements of the economy, improved energy efficiency could be increased.

Existing organizations and conservative political groups. Most Republicans do not support renewable energy investment because their framework is built on staying current with energy sources while promoting national drilling to reduce dependence on imports. In contrast, progressives and libertarians tend to support renewable energy by encouraging job growth, national investment and tax incentives. Thus, polarized organizational frameworks that shape industrial and governmental policies for renewable energy. According to an article by Henrik Lund, the theory of Choice Awareness seeks to understand and explain the best possible alternatives. The theory argues that public participation, and hence the awareness of choices, has been an important factor in successful decision-making processes. Given these conditions leaves the public with a situation of no choice. Therefore, this leaves the general public in a state of abide by In a broad sense most individuals, especially those who do not engage in public discourse of current economic policies. Enlightening communities on the socioeconomic implications of fossil fuel is a potent mode of rhetoric that can promote the implementation of renewable energy sources. Transparent local planning also proves useful in public discourse when used to determine the location of renewable energy. According to an article by John Barry et al., “Crucial factor communities need to engage discourse on the principle of” assumption of imperative and consensus. This principle claims that a community can not neglect its energy or climate change. Hence, communities that continually engage in mutual learning and discourse by conflict resolution.

Legislative definitions of renewable energy, usually excludes nuclear energy. Physicist Bernard Cohen elucidated in 1983 that uranium dissolved in seawater, when used in Breeder reactors (which are more likely to be fissile nuclear fuel than they consume from base fertile material) is effectively inexhaustible, with the seawater bearing uranium constantly replenished by river erosion carrying more uranium into the sea, and could be considered a renewable source of energy. In 1987, the World Commission on Environment and Development (WCED), an organization independent from, but created by, the United Nations, published Our Common Future, in which breeder reactors, and, when it is developed,
