Solar energy is really our only answer for long-term sustainable energy

Humans consume 221 tonnes of coal, 1,066 barrels of oil, and 93,000 metric cubes of natural gas every second.

Sooner or later humanity needs to get its head around the fact that the only long-term sustainable energy solution is solar energy.

The theoretical potential of solar power is 89 terawatts, which represents more energy striking the Earth’s surface in 90 minutes than the worldwide energy consumption for the entire year from all other resources combined.
