If you look in to the recent 30 years database about climate, then you will find out how much changes our weather in comparison to previous situation. We all are familiar with the reason, nothing but increasing carbon dioxide at a alarming rate. Fossile fuel is the main responsible for occuring this situation. If we can use more solar energy then we can reduce damage. We should take measure to resolve problem and should consider using of renewable energy.
I think that solar energy is not yet very promising technology. Too little energy comes from solar panels. The cost of solar energy production higher than any other. I think that the future of nuclear energy. Although it's not the most environmentally friendly method of energy production. It can better improve the safety and disposal of nuclear waste than to figure out how to get an extra 1 kilowatt from solar panels?
Despite the fact that Japan is the most advanced country in the world in the sphere of high technologies, you have already realized that nuclear energy is very dangerous. Therefore, you need to try to use alternative sources Following the example of the sun, wind and high-speed rivers.
