Why solar photovoltaic power generation is a kind of green low carbon energy?

Photovoltaic (pv) power generation has significant energy, environmental protection and economic benefit, is one of the high quality green energy. Under the condition of our country average sunshine, photovoltaic power generation systems within the whole life cycle energy return for more than 15 times more than its energy consumption and carbon emissions by photovoltaic

photovoltaic (pv) power generation has significant energy, environmental protection and economic benefit, is one of the high quality green energy. Under the condition of our country average sunshine, photovoltaic power generation systems throughout the life cycle energy return for more than 15 times of the energy consumption and carbon emissions by photovoltaic is only about 5% of the coal. The eu proposed to the photovoltaic power generation account for 15% of the total generating capacity of 2030 grand vision. The world developed countries regard it as a strategic emerging industries, and achieved rapid development in the past 20 years. China is facing more serious energy and environmental pressure. If the reference to the European Union's 15% photovoltaic target, by 2030, China pv total installed capacity will reach 10. 500 million kilowatts, calculated at 1200 hours of electricity, power generating capacity is 126 billion KWH, equivalent to 25% of the total electricity consumption in 2012, saving 4. 0. 8 billion tons of standard coal, reducing carbon dioxide emissions from about 9. 900 million tons. Sulfur dioxide, nitrogen oxides and dust emissions reached 9. 14 million tons, 1. 84 million tons and 230000 tons of coal to produce solid waste emissions reduced by 1. 31 400 million tons, reduce water consumption. 7. 5 billion tons. According to the world wide fund for nature ( 世界自然基金会) Research, in terms of co2 emission reduction effect, and install solar photovoltaic power generation 1 square metre is equivalent to 100 square meters of afforestation, development of renewable energy sources such as photovoltaics will fundamentally solve the smog, acid rain and other environmental problems.
