Denmark
Wind energy, generated largely by high-volume offshore mills, was used to supply 18.3 percent of the nation’s electricity last year. In America, wind power accounted for 0.8 percent.

France
The nation relies on nuclear energy for 78 percent of its electricity. France consumes about 440,000 gigawatt-hours of nuclear-­powered electricity, whereas only 19 percent (806,500 GWh) is nuclear in the U.S.

Germany
A world leader in solar-powered electricity, Germany draws 0.6 percent of its electricity from the sun, amounting to 3,500 GWh. That’s roughly 3,000 GWh more than America gets from solar power.

Iceland
Geothermal power generates 30 percent of the electricity on this volcanic island. Proportionally, that is more than 100 times the amount that geothermal energy supplies to the electricity grid in the U.S.

Norway
One of the world’s leading producers of oil, Norway nonetheless relies on hydroelectricity for 98 percent of its electric power—compared with 6 percent in the U.S.
