Portugal ran for 4 days only on renewable energy
According to a report by Portuguese NGO 'Zero', the country was powered entirely on renewable energy for 107 hours last week. In 2013, Portugal generated half its electricity from combustible fuels and 23.5% from hydro, wind and solar, according to an EU directive. Notably, Portugal was set a target to generate 31% of its energy from renewable sources by 2020.
