The area of illuminate of sunlight scattered in the earth's most corner, just different incident Angle of light have different, but at least not monopolized by a few countries or regions, causing unnecessary energy crisis.

the area of illuminate of sunlight scattered in the earth's most corner, just different incident Angle of light have different, but at least not monopolized by a few countries or regions, causing unnecessary energy crisis.
the solar street lamp manufacturers estimates that in the past one billion one hundred million years, long the sun only consumes 2% of its energy, billions of years in the future the sun will not have obvious change, so the sun can be a permanent human energy, inexhaustible, an inexhaustible. It gives the ground energy, 15 minutes is enough to use a year around the world.
nuclear power will have the risk of nuclear leak, once the nuclear leak will cause tremendous ecological crisis, there is absolutely no this kind of situation, and solar energy is very reliable.
a light pole, solar energy is a kind of clean energy, no any harm the environment, for now the earth's environment, using solar energy is an inevitable trend.
2, the universality of solar energy, sunrise and sunset natural cycle, we can use the solar energy during the day, but now the solar energy utilization technology remains to be a breakthrough, such as solar water heater, wet weather would not be very good to produce hot water.
3, solar energy cost is low, solar energy as energy is free.
4, solar huge sex, on the surface of the solar radiation that reaches the earth each year about 130 trillion tce, its total current can be developed in the world's largest energy.
5, solar energy has been exist for a long time, according to the current produced by the sun nuclear rate estimation, the hydrogen capacity enough to maintain billions of years, it can be said that the sun's energy is inexhaustible.
