"While I welcome Ed Miliband's call for political agreement on green issues, this is something I have been encouraging for a long time.

"If Miliband is serious about tackling climate change he should stop threatening to choke the renewables industry with his price freeze.

"The Liberal Democrats are the party of green, delivering in government on green energy and jobs.

"This Government is doing more to tackle climate change than any other Government before, with renewable energy investment higher than at any time under the last Government. "

The Liberal Democrats are working hard in Government to address climate change issues and have a strong record of delivery investing in clean energy and green jobs, with the recently introduced Energy Act creating 200,000 jobs in renewable energy by 2020.

Since 2010, around £40 billion has been invested in new electricity infrastructure- overhauling the record under the last administration in just over three years.

The Liberal Democrats in Government have pushed for the ambitious target of a 40% reduction in greenhouse gas emissions across the EU and for reform of the EU emissions trading system.

However, Labour's energy bill proposal threatens investment in green energy as it will push up prices for consumers, do nothing to reduce emissions and destroy competition by solidifying the power of the Big six.

Comment from John Wheaver - Kettering and Wellingborough

Ed Davey is speaking as a member of a Conservative-led coalition.

The question of paying the price of green energy has not been addressed. Higher bills cannot be paid by many people; green energy is essential and (at least initially) costs more. None of the answers is comfortable to live with, but neither should be avoiding the question.
