Portugal has announced that it has provided all of its power through renewable sources for four days.
Wind, solar and hydro power kept the nation’s lights on over the 107-hour period from 6:45am on Saturday, May 7 to 5:45pm Wednesday, May 11.
At no point during the period did the nation have to use coal or natural gas production plants.
SolarPower Europe CEO James Watson says it’s an incredible feat, but it’ll be common in the continent within just a few years.
The four days ran during the northern hemisphere’s spring and it’s hoped Portugal can produce even more clean energy once the sunny summer kicks in.
