The European Union is hoping to reduce energy use across member states by up to 20%.
But it wants countries to volunteer to cut energy use, which has drawn criticism from environmental campaigners.
The move comes alongside current Europe-wide drives to shift towards renewable energy sources and cut emissions.
The EU originally wanted mandatory targets for cutting energy use - but that was opposed by Germany.
The new directive instead asks European governments to volunteer to meet the targets.
As part of a raft of measures, the EU also wants energy suppliers to help cut consumer's energy useÂ by encouraging them to use less power and be more energy-efficient. If implemented, that would mean cheaper gas and electricity across the continent, but would reduce sales for suppliers by 1.5% year on year.
United Press International also reports that Governments are also being encouraged to improve energy efficiency across three percent of their public buildings every year.
