Get know about 'Green Energy'

With the development of the society, all the countries notice that using only fossile fuel can causes big problem like the glabal warming and also else. So how to replace fossile fuel with minimum side effect become ugent to governments. Some countries use natural gas and nuclear power to produce electricity or other energy that they want, but it seems the side effects are also obviously. Therefore, green energy, also know as renwable energy, starts to be noticed. (In addition, there is a debate about wether nuclear power is renwable energy or not.)

So, as you can see, there are many kinds of renewable energy show in the figure above. But there are also different limitations for each kind of renewable energy. For instance, solar power only can be used efficiently at the place where receives plenty of solar energy. In the same way, wind power also has a minimun requirement for the wind speed. Moreover, the relevant equiments fot these renewable energy also needs proper maintenance. In the UK, wind power is the most popolar one, it supplied almost 10% of eletricity demand for the country. At the coastal cities, wave power is also used commonly to produce electricity. And solar power is very mature technology now which is actually ustilized all over the coutry now.

Therefore, it can be seen that renewable energy becomes more and more important to out world now. It will not only reduces the effects of global warming, but also can propduces certain part of energy demand for each country.
