The UK's Renewable Energy Association (REA) has called on European heads of state to decide on renewable energy targets for European Union (EU) Member States in the 2030 energy and climate framework.
EU is to decide on the binding targets for renewable power generation in a meeting to be held on 23 and 24 October 2014.
REA expects stronger 2030 targets to transform renewable into the cheapest low carbon power supply option across industries with zero subsidy.
The proposed targets by the European Commission for renewables across the EU are "at least 27%" (alongside a 40% reduction in greenhouse gases and a 30% increase in energy efficiency), which is deemed weaker than the 2020 target of 20%.
REA stated the Commission's target for 2030 to be unambitious. In addition to this the REA stated it is 'not binding on individual Member States'.
REA chief executive Dr Nina Skorupska said: "People working in UK renewables simply don't know whether the government wants the industry to keep growing or not. There have been so many mixed signals this Parliament that it has become almost impossible for our members to plan and invest for their future.
"2030 renewables targets for Member States will give businesses the certainty they need.
"If this doesn't happen, it will be up to the UK Government to set out its own vision for renewables in the 2020s and beyond.
"As renewables businesses are usually smaller and younger than fossil fuel and nuclear companies, a 'technology neutral' framework will leave them at a disadvantage. With clear market signals though, renewables will be the cheapest source of low carbon energy, without the need for subsidy, well before 2030."
Implications of the final 2030 energy and climate framework will be analysed by the organisation at an event to be held in London on 4 December 2014.
