Earlier this month the country of Portugal powered itself entirely from renewable sources of energy for 107 consecutive hours – that’s 4 days, 11 hours. And don’t let that image fool you. It’s not all rolling hills and countrysides – the country is home to more than 10 million people, so this is a remarkable feat for sure. Read more here at the Guardian.
Portugal kept its lights on with renewable energy alone for four consecutive days last week in a clean energy milestone revealed by data analysis of national energy network figures.
Electricity consumption in the country was fully covered by solar, wind and hydro power in an extraordinary 107-hour run that lasted from 6.45am on Saturday 7 May until 5.45pm the following Wednesday, the analysis says.
News of the zero emissions landmark comes just days after Germany announced that clean energy had powered almost all its electricity needs on Sunday 15 May, with power prices turning negative at several times in the day – effectively paying consumers to use it.
To be clear this does not mean that no consumable fuels were used during this period, but rather that demand – at least at homes and buildings on the grid – was met with renewable sources, putting more energy into the grid than was being used.
