- Will Never Run out: The Sun has sufficient helium mass to provide the Earth with energy for another five billion years. It emits enough energy to power humankind for an entire year in 1/816,000th of a second!
- Just a fraction of it: The Earth receives only one half of one billionth of the Sun’s radiant energy, but in just a few days it gets as much heat and light as could be produced by burning all the oil, coal and wood on the planet.
- Clean, cheap and free: Worldwide, some two billion people are still without electricity. For these populations it is more economically viable to install solar panels than to extend established electricity grids.
