The group includes Anaerobic Digestion and Biogas Association, the British Hydropower Association, the British Photovoltaic Association, the Renewable Energy Association, RenewableUK, Scottish Renewables and the Solar Trade Association.

The group intends to encourage public support for renewable energy and is chaired by environmentalist Tony Juniper.

According to the group, renewables can deliver 15% of the country’s total electricity needs by 2020, increasing to a 30% share by 2030 with implementation of stable policies.

The group urged all parties to support the Climate Change Act and the emissions target to tackle climate change.

It urged for a commitment to fund the Renewable Heat Incentive after 2016 to increase the UK’s Renewable Transport Fuel Obligation to reach the 10% renewable energy target for transport by 2020.

Juniper said: "The renewable energy bodies have come together with clear and simple propositions.

"We need consistent and strong backing for renewable energy, not only to cut carbon emissions and tackle climate change, but also to harness the opportunities for growth and jobs and reduce our reliance on dirty fossil fuel imports from insecure parts of the world.

"A range of technologies have important roles to play and I hope voters will contact Party Leaders and ask them to support out manifesto because none of these technologies can flourish without political backing."
