  1. sun lights and heats the earth thermal energy warms photovoltaic power stations chlorophill photosyntesis water-earth-air food and O2 for all livings beings water cycle wind(wind power) athmosferic fenomena animals dead =fossilitation Power stations

  2. Solar Energy A solar pannel is made of specia cells which have two layers One of these layers has far more electrons than the other When sunlight hits the cell,the electrons become excited They start to jump over to the layers with more electons This flow of electrons is what we call electricity,and it can be harnessed to power anything from calculators to cars A

  3. energy can be renwabole non renwable when it runs out when we used it forever it can't be used up metan, oil, natural gas, uranium solar-wind-biomass -geothermal-thermal energy,oceans
