A 100% renewable grid isn’t just feasible, it’s already happening

New study debunks myths claiming renewables can't be integrated into electric grid.

The ongoing debate around whether it’s feasible to have an electric grid running on 100 percent renewable power in the coming decades often misses a key point:  many countries and regions are already at or close to 100 percent now.

According to data compiled by the U.S. Energy Information Administration, there are seven countries already at, or very, near 100 percent renewable power: Iceland (100 percent), Paraguay (100), Costa Rica (99), Norway (98.5), Austria (80), Brazil (75), and Denmark (69.4). The main renewables in these countries are hydropower, wind, geothermal, and solar.
