How natural gas supports renewable energy
Natural gas and renewables are highly complementary energy sources. Together, they are the best way to reduce greenhouse gas emissions. Because energy storage technology is not yet viable for fast-ramping energy generation, natural gas provides renewable energy like wind and solar with the flexible back-up power required to quickly respond to fluctuations in the power grid's supply and demand. Grid-scale battery technologies may not become available until 2040, and natural gas will provide crucial support to renewables until then.
