All of Portugal Is Powered by Sun, Wind, Water for 4 Days Straight

Portugal was able to sustain its nation of 10.4 million people completely on renewable energy for a record four whole days.

Portugal is turning to wind, wave and solar power to reduce its huge dependence on oil imports and meet its international commitments to reduce carbon dioxide emissions. The bulk of the 2.5 billion euros (2,9 billion dollars) in private and public funds that the government of Prime Minister Jose Socrates set aside in July 2005 to develop renewable energy will go toward wind energy development.

Portugal was able to sustain its nation of 10.4 million people completely on renewable energy for a record four whole days. 

Four-and-a-half days, or 107 hours, to be more exact 

From 6:45am, local time, on May 7 until 5:45pm on May 11, the electricity grid of the Iberian nation was sustained completely by solar, wind, and hydro power, according to data from Portugal’s National Energy Network (REN)

Portugal, who in 2014 had a population of 10.4 million, has a rapidly expanding renewable energy industry. 

According to European statistics, Portugal generated only 23 percent of its electricity from solar, wind, and hydro sources in 2013.
