Energy management includes planning and operation of energy production and energy consumption units. Objectives are resource conservation, climate protection and cost savings, while the users have access to the energy they need. It is connected closely to environmental management, production management, logistics and other established business functions. The VDI-Guideline 4602 released on the definition of the economic dimension: “Energy management is the proactive, organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, taking into account environmental and economic objectives”.

Renewable energy
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human scale, such as sunlight, wind, rain, tides, waves and geothermal heat. [2] Renewable energy often provides energy in four important areas: power generation, air and water heating and cooling, rural transportation and energy services (off grid) . [3]
Renewable energy overview
PlanetSolar, the largest solar boat in the world and the first solar electric vehicle to go around the world (in 2012)
Renewable energy flows involve natural phenomena such as sunlight, wind, tides, plant growth and geothermal heat, as explained by the International Energy Agency: [19]

WIND POWER
Airflow can be used to operate wind turbines. Modern wind turbines on an industrial scale range from about 600 kW to 5 MW of rated power, although turbines with a nominal power of 1.5-3 MW have become the most common for commercial use. The largest generation capacity of a single onshore wind turbine installed reached 7.5 MW in 2015. The available wind power is a function of the cube of the wind speed, so that when the wind speed increases, the power increases. until you reach the maximum power. particular turbine. [41] Areas with stronger and more consistent winds, such as offshore sites and high altitude, are prime locations for wind farms. Loading times generally fullThe wind turbines vary between 16 and 57% per year, but could be higher in particularly favorable offshore sites. [42]
MARKET AND INDUSTRY TRENDS
Main article: Marketing renewable energy
Renewable energy has been more effective in creating jobs than coal or oil in the United States. [79]
EMERGING TECHNOLOGIES
Other renewable energy technologies are still under development and include cellulosic ethanol, dry and hot geothermal energy, and marine energy. [154] These technologies are not yet widely proven or have limited commercialization. Many are on the horizon and may have potential comparable to other renewable energy technologies, but they still depend on attracting sufficient attention and funding for research, development and demonstration (RD & D) .
