The most popular form of Green Energy today is Solar Energy with an estimated 700 GW (gigawatts) of annual capacity globally.
Here's a rough estimate of the global capacity for each of these forms of green energy:
Solar Energy: 700 GW (gigawatts)
Wind Energy: 600 GW
Hydro Energy: 1,200 TWh (terawatt-hours)
Geothermal Energy: 12 GW
Biomass Energy: 60 GW
1 GW is equal to approximately 8.76 TWh
These numbers are constantly changing as new projects come online and technology improves.
