Indispensable Erengy

        Our human need a indispensable energy , it is solar erengy. Because everything needs sunshine, if we lose the illuminate of Sun, then from death is not far away. So the sun is our human mother, solar energy is the most important one of the new energy, no.
         With the decrease of the fossil energy, the improvement of mankind energy demand year by year. The renewable erengy resources make it important. Solar erengy is a new erengy that have a lot of advantage power. For example, it is a clean source of energy. The fossil fuels that we use today are the main source of the pollution in our atmosphere. So if we use solar erengy, we can reduce a lot of atmosphere pollution. Sencondly, solar erengy is a cheaper erengy. We can use photovoltaic cells changes sunlight directly into erengy, So we can make a cheaper energy-solar erengy. Thirtly, we  can protect our Earth if we use solar. Because when we burn fossil erengy, it can pollute our atmosphere.
             All in all, Using solar erengy is aindispensable energy, our human need to vigorously develop the solar energy field.
