As recently as 2013, renewables provided only about 23% of Portugal’s electricity. By 2015 that figure had risen to 48%. Photograph: Pete Titmuss/Alamy Stock Photo Zero emission milestone reached as country is powered by just wind, solar and hydro-generated electricity for 107 hours

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.
Oliver Joy, a spokesman for the Wind Europe trade association said: “We are seeing trends like this spread across Europe – last year with Denmark and now in Portugal. The Iberian peninsula is a great resource for renewables and wind energy, not just for the region but for the whole of Europe.”
