My renewable solar energy is solar and it comes from the sun that is converted into thermal or electrical energy. In the basque country we use only 1,8% of all the amount of energy, because its very expensive and takes a lot of space. Solar energy can work in three different ways: the solar cells absorb the sunlight and makes the solar energy into electric energy, another is the solar water heating: the sun heats the water with the glass panels and they don´t use so much gas or electricity to heat the house, and the last one is that a large amount of mirrors concentrate all the heat in a small space and it produces very high tenperatures. Solar energy was created in the 7 century B.C. To today. They started to concentrate the sunlight to create fire. The impact of this renewable energy in the enviroment is that it needs a lot of land and the habitats loss, water use and the use of hazardous materials manufacturing it. But it doesn´t have toxic pollution or global warming emmisions. The dangers are that to use it we have to use hazardous materials and solar energy is produced like the nuclear fusion in the nuclear power plants and it has the same physic laws that the atomic bomb. To put solar energy in your house costs 10000$ and a residential area between 3kW to 8kW and end it up costs between 15000$ and 40000$
