Our story of energy begins when humans discovered the secret of fire. We burned wood and brush to protect ourselves from predators, cook food, and, later, to survive the ice age. In 12th-century Europe, with the forests fast disappearing, we started burning the strange black stones we called coal. Later, we used coal to produce steam, launching the Industrial Revolution.

Spiegel Online published a series of pictures titled "Desertec: Strom aus der Wüste" (translation: Desertech: Electricity from the desert). It includes this image of how much land would be needed to power the world, Europe or Germany with solar-thermal power. The idea is similar to a post we did a year ago: How Much Land to Power The Whole World with Solar?

The sun blasts Earth with enough energy in one hour—4.3 x 1020 joules—to provide all of humanity's energy needs for a year (4.1 x 1020 joules), according to physicist Steven Chu, director of Lawrence Berkeley National Laboratory. The question is how to most effectively harness it. Thin-film solar cells may be the answer: One recently converted 19.9 percent of the sunlight that hit it into electricity, surpassing the amount converted into power by mass-produced traditional silicon photovoltaics and offering the potential to unleash this renewable energy source.
