U.S. electricity generation from renewable sources such as wind and solar to surpass nuclear and coal by 2021 and to surpass natural gas in 2045.

Wind power is one of the most important drivers of Germany’s transition to renewable energy and a related target for green energy to reach 65% of electricity production by 2030 will be missed at the current rate of turbine growth,

U.S. renewable energy consumption totaled 924 trillion British thermal units (Btu), which accounted for 12% of U.S. total primary energy consumption.

Australia added 6.3 GW of new renewable capacity in 2019, against 4.8 GW in 2018

Renewables only accounted for 18.2% of total energy generated by November 2019, while coal alone produced 23.4% of the country’s electricity.

global electric power generation from renewable sources will increase more than 20% throughout the projection period (2018–2050), providing almost half of the world’s electricity generation in 2050. In that same period, global coal-fired generation will decrease 13%, representing only 22% of the generation mix in 2050.

Academics and concerned citizens often ask "how long" will it take for the global economy to transition to zero carbon energy systems in the transportation, electric generation and heavy industry sectors.

a sharp rise in the Germany’s renewable generation capacity was needed over the next 15 years to meet demand from the electrification of heating, transport and other industries.

A “clean energy resource” is defined as “any technology used to generate electricity without emitting carbon dioxide into the atmosphere,” including “(i) electric generation facilities that are powered by nuclear, solar, wind, falling water, wave motion, tides, or geothermal power; (ii) a natural gas-fired generation facility with 80 percent carbon capture; or (iii) a coal-fired generation facility with 90 percent carbon capture.”

Solar and wind power use has grown at a rapid rate over the past decade or so, but as of 2018 those sources accounted for less than 4% of all the energy used in the U.S.
