In order to cope with global warming, control global air pollution, and promote energy transformation, renewable energy has become the main force of future development. Solar energy, with its inexhaustible feature, is one of the fastest growing energy sources in renewable energy.
McKinsey predicts that solar power will explode 60 times between 2015 and 2050, after which solar energy will become the world's leading energy source. Similarly, this prediction is confirmed with the data provided by the International Renewable Energy Agency's (IRENA) 2050 Global Energy Transformation Road map (GET2050) report. According to the report, the total power generation of renewable power in the world will climb from the current 26% to 85% in 2050, of which up to 60% comes from solar and wind.
With restriction of policy, technology and market conditions, solar energy development speeds vary from country to country.The analysis shows that in Germany and Spain, the development of solar photovoltaic power will enable the solar industry to achieve a cost parity with natural gas and coal around 2020. Following these pioneers is India and Australia, where photovoltaic solar energy will catch up with natural gas in 2020.
