A total of 173,000 terawatts (trillions of watts) of solar energy strikes the Earth continuously. That's more than 10,000 times the world's total energy use.

The IPCC reported geothermal power potential to be in the range of 35 GW to 2 TW.

The wind is always blowing. The tides are always shifting.

We're drowning in potential energy. We just need to collect it.
