European Commission Vice President Maros Sefcovic today called it "undoubtedly the most ambitious energy project" since the inception of the EU over half a century ago. It will include improving links across borders in Europe's oil, gas and electricity grids and investing in new sources of energy from North Africa and Turkey.
Sefcovic said that could save businesses and consumers up to 40 billion euros (USD 45.4 billion) a year and, by diversifying energy sources, increase the EU's political options in eastern Europe.
"Our dependence on external energy resources has affected our ability to conduct an independent foreign policy," warned the leader of the European Parliament's liberal ALDE group, Guy Verhofstadt.
He said an ambitious energy project will create jobs, tackle climate change and hit Russian President Vladimir "Putin where it hurts most."

Environmental groups were quick to criticize the plan, saying it focuses too much on Russia and fossil fuels rather than renewable energy sources.
"We keep hearing repetitions of gas, gas, gas," said Brook Riley from Friends of the Earth Europe. "The EU risks throwing hundreds of billions of euro into pipelines that it will have to decommission almost as soon as they come online because they contribute to climate change."
The proposals will form the basis for future legislation. As a first step, EU environment ministers will debate them on March 6.
