Using Only Renewable Energy, Portugal Powered Its Entire Country for Four Days

Portugal just did something pretty amazing. In fact, it’s historic — something no other nation has ever done. Portugal just powered its entire country’s electricity needs for four consecutive days using nothing but renewable energy.

Using a combination of solar panels, wind turbines, biofuels, geothermal heat and hydroelectric power, Portugal powered everything requiring electricity for 107 hours between Saturday morning, May 7, 2016, and Wednesday evening, May 11, 2016. The country’s ZERO System Sustainable Land Association, in collaboration with the Portuguese Renewable Energy Association, released information about this impressive achievement on its website.
