Danish government proposals on Friday called for sourcing just over half of its electricity from wind turbines by 2020, and all of its energy from renewable sources in 2050. 

The government also invited the parties in parliament to negotiations on the proposal to shape energy policy to 2020.

Denmark will take over the presidency of the European Union for six months from January 1 and aims to promote ambitious climate and energy goals for Europe.

It is already the world leader in wind power, getting a fifth of its power from wind turbines.

"This is an historical effort to become even better at saving energy and create an even more competitive and energy-effective company culture in Denmark, also for households," Minister for Climate, Energy and Building Martin Lidegaard said.

The portion of Denmark's electricity from wind and other renewables would rise to 52 percent by 2020 under the new plan, topping a 50 percent target in a government policy program adopted last month.
