Earth Energy Balance:

All energy to Earth surface is 99.98 % solar, 0.02% geothermal, and 0.002% tidal-gravitational.

About 13 TW world energy consumption rate now (0.007% of solar striking Earth) is about 7 times smaller than global photosynthesis (all life), the latter is only 0.05% of total solar, and global atmospheric water and wind are about 1% of solar.
