Humanity tries to develop new types of energy, for example, wind, solar, or hydrogen energy. In this post I would like to tell about developing of solar energy. A lot of energy resources are limited. As for solar energy, Earth can get limitless solar power from the sun and people use this opportunity. We use solar power to "produce electricity without releasing any
greenhouse gases."(Cass, Stephen,Sep/Oct2009, p93) Europeans have already installed a solar roof to get electricity from the sun; but this way of getting electricity is not cheap. The scientists explore new and cheap ways to get solar power: silicon based photovoltaics. We will use these technologies only in future. Besides, in future humanity will be able to use solar cells out of organic polymers and harnessing solar energy to split water into oxygen and hydrogen will appear. It will be nano-technologies which change our world. If the USA explore these technologies, Americans can forget about the electricity problems.
