The Spanish Government proposed to double production from renewable energy sources by 2020 to just over 20% of total energy use, to meet European Union targets.
Renewables production in Spain is predicted to be the equivalent of 27.9 million tons of petroleum by 2020, up from 11.96 million tons in 2009, according to Reuters.
Spain's wind power sector is expected to increase its capacity from the existing 18,300MW to 40,000MW in 2020, while solar power generation will rise to 15,685MW from the present 4,168MW.
The nation's nuclear power capacity is expected to go down by 460MW when the aging Garona plant is closed in 2013.
The government plans to phase out nuclear power, but most plants will operate through to 2020 or beyond.
