While Trump promotes coal, other countries are turning to cheap sun power

The Washington Post reports: On the solar farms of the Atacama Desert, the workers dress like astronauts. They wear bodysuits and wraparound sunglasses, with thick canvas headscarves to shield them from the radiation.

The sun is so intense and the air so dry that seemingly nothing survives. Across vast, rocky wastes blanched of color, there are no cactuses or other visible signs of life. It’s Mars, with better cellphone reception.

It is also the world’s best place to produce solar energy, with the most potent sun power on the planet.

In Chile and a growing list of nations, the price of solar energy has fallen so much that it is increasingly beating out conventional sources of power. Industry experts and government regulators hail this moment as a turning point in the history of human electricity-making.
