The old and the new stand in stark contrast during Johan Norberg's visit to the Sahara, where ancient towns are being electrified in a dramatic new effort to bring "Power to the People."

This European field of nuclear plant cooling towers highlights a major reason for Germany's quest to turn its back on coal and other fossil fuels. Citing the full-on disasters at Fukushima and Chernobyl, Germany is deliberately pulling the plug on nuclear.

“Power to the People” reveals, in a visit to a solar energy facility in Morocco, how the planet is only at the dawn of the changes this still-to-be widely tapped renewable energy source will bring.

Half the world still cooks over open flames, often indoors, exposing families to smoke hazards. "Power to the People" host Johan Norberg reveals how that is all changing and increasing energy demands - including this kitchen in Morocco, food is now prepared on a burner fueled by cooking gas. There are also refrigerators – major changes vastly increasing the standard of living.

Another positive development in the drive to reduce emissions is taking place in the American trucking industry. Saddle Creek Logistics in Florida is converting its diesel fleet to one run by natural gas.

Denmark has bet its energy future on wind – and the government is working toward a year 2020 goal to produce 50% of its power from this sustainable source. With 28% of its power supply now coming from wind, the Danes are halfway there.

Some Americans have chosen to live completely off the grid, and produce their own electricity, mostly with solar power. Here, “Power to the People” host Johan Norberg visits one such community, Oregon’s Three Rivers.
