Global Supporting to Promote Green Energy
Government will subsidize the investment for building solar or wind power plant, or increase the tariff of electricity generated by green energy.
Up to 15% (or more) of the total electricity generated by green energy by the end of 2020 in many countries.
Issue Strong Supporting Policies
Strong Subsidy Supporting
During the past years, the cost of solar panel, wind turbine, inverter and other equipment has been reducing greatly. Nearly 1USD/W of solar module , and 0.2USD per Watt for inverter system now.
Cost Reducing Greatly
