Voters across Europe have lost faith in politics partly because of “unachievable targets” on renewable energy, said German Energy Minister Peter Altmaier, who rejected calls from a group of other EU countries to boost the share of renewables to 33-35% of the bloc’s energy mix by 2030.

Altmaier made the comments during an on-the-record exchange between the 28 EU energy ministers.

Energy ministers are expected to thrash out a joint position on three clean energy laws which are currently being negotiated in the EU institutions – the Renewable Energy Directive, the Energy Efficiency Directive and a regulation on the Governance of the Energy Union, according to Euractiv.com.

“Germany supports responsible but achievable targets,” Altmaier said from the outset, underlining Berlin’s efforts to raise the share of renewables to 15% of the country’s overall energy mix.

But he said those efforts also carried a cost for the German taxpayer, which he put at €25 billion per year. “And if we are setting targets that are definitely above 30%, that means that within a decade, our share has to be more than doubled – clearly more than doubled,” Altmaier pointed out.

“We’re not going to manage that,” Altmaier said referring to an objective of putting 1 million electric vehicles on the road by 2020 in Germany. “Nowhere in Europe is going to manage that,” he claimed. “And even if we did manage to get enough electric cars, we wouldn’t have enough renewable electricity to keep them on the road,” he stressed.

What’s needed, he said, is “a compromise that prevents us from having an unachievable target” at European level. “Citizens across Europe are losing faith in politics. When they see that we are setting very ambitious targets and that a few years later we’re deferring this, we are way off their expectations.”
