Prospects of the development of solar and wind and solar energy street light

Solar and wind and solar energy street light it is estimated that the prospect of development of annual solar radiation to the earth is 17. 800 million kw, which can be the development and utilization of 500 ~ 100 billion degrees. But because of its distribution is very scattered, now can use the effect. The world wind energy potential is about 350 billion

it is estimated that annual solar radiation to the earth is 17. 800 million kw, which can be the development and utilization of 500 ~ 100 billion degrees. But because of its distribution is very scattered, now can use the effect. The world wind energy potential is about 350 billion kw, because wind discontinuous scattered, difficult to economic advantage, can lose energy storage technology in the future if there are any significant improvements, wind use will increase. In 2009, domestic solar battery capacity is about 2. 4 million kw, but domestic solar power installed capacity is 120000 kw, only 95% of the export capacity, which is the most important market in Europe. Over the past few years, Europe has been the focus of the world solar photovoltaic power generation. In 2009, Germany, Spain, Italy and the Czech republic of new installed capacity of more than 4. 2 million kw, 60% of the world.
