GRAZ, Austria (Reuters) - A European Union official urged member states on Saturday to ween big energy consumers off conventional fuels onto renewable sources of energy. She said a 12 percent share of renewable energies in the EU fuel mix was still a target for 2010 and called on the 15nations to set their own national targets for the so-called renewables, such as wind, wave, solar and electricity. „Without such targets, the contribution that renewables can make to meeting our Kyoto commitments are not defined, the political will to promote renewables is uncertain and results cannot be evaluated,“ said EU Environment Commissioner Ritt Bjerregaard at an informal meeting of EU environment ministers. The EU committed itself at the U.N. climate talks in Kyoto, Japan, last December to cut emissions of six greenhouse gases like carbon dioxide (CO2) to eight percent below 1990 levels by 2008-2012. To honour this commitment, the EU needs to convince big energy consumers to switch from conventional fuels like oil, coal, gas and nuclear onto renewable energies. The EU aims to double the share of renewables in the EU fuel mix to 12 percent by 2010. „In developing your national strategies on climate change it is imperative that you work with your energy colleagues to set quantified national targets for renewables,“ Bjerregaard said. A raft of incentives, such as tax breaks, is being discussed to promote renewables so that investment in clean energy sources becomes attractive.
