Solar thermal systems are therefore now included in our standard piece of equipment in new homes. The energy produced by the heat of solar collectors can be used for heating, showers, dishwashers and washing machines. Two variants are available for electricity generation: Solar cells convert sunlight directly into electricity. The government financially supports the use of this technique, called photovoltaics, through the Renewable Energy Sources Act (EEG). The accounts are solar thermal systems in sunny countries. Thanks to large mirrors, sunlight is concentrated, converted into heat and driven by steam turbines. The generated electricity can be transported as direct current over long distances. Such solar power plants are already in operation in Spain and California. Wind energy is the oldest form of energy used by humans. In ancient times people made wind energy, life and work easier. Evidence of this use are the old wind turbines that have been used for various purposes such as the promotion of groundwater. In the strictest sense, wind energy is an inexhaustible source of energy, such solar energy is influenced by the sun's radiation on the earth. Because of
