The Federal Government is copping criticism from within its own ranks over the much-decried decision to stop the Clean Energy Finance Corporation (CEFC) from investing in large wind farms and household solar.

The has been no shortage of hubbub since Treasurer Joe Hockey and Finance Minister Mathias Cormann directed to the $10 billion taxpayer-funded CEFC to cease funding the popular renewable projects.

Now, LNP backbencher Sarah Henderson has called for the new directive to be reversed, because renewable energy is an important issue for residents nationwide, including in her Victorian electorate of Corangamite.

“I've written to the Finance Minister Mathias Cormann seeking his consideration that emerging technologies in wind and small-scale solar be included in the Clean Energy Finance Corporation's investment mandate,” Henderson told reporters this week.

She said Mr Cormann had been fairly attentive to her concerns, but conceded she was just “one cog in the wheel”.

“It's very important not to exclude small-scale solar and also wind, because there are new and emerging technologies in these sectors as well,” she said.

Over the weekend, Opposition Leader Bill Shorten used the ALP conference to mark out his own views, threatening to run the next election on climate policy.

He ridiculed “Mr Abbott's society of flat earthers”, while accusing the Government of destroying confidence in Australia’s renewable energy industry.

“This line that Labor is running that we are not for renewables is absolute rubbish,” Ms Henderson said.

The CEFC has stated that it will provide a response to the Government's draft investment directive “in coming weeks”.
