The ACT Government wants more power for less, and so is allowing itself a greater share of renewable sources.

A bill has been tabled to expand the amount of Canberra's electricity which can be provided by renewable energy.

If passed, it would mean that 90 per cent of Canberra’s energy could come from wind, solar, geothermal or other sources.

Environment Minister Simon Corbell says as with all renewable expansion, initial costs are high, but he believes that the price will quickly be offset by ever-increasing fossil fuel costs.

“Just in the last week we've seen a major announcement about big increases in gas prices and we can expect those types of costs of fossil fuels to continue to go up over time,” Mr Corbell said.

The changes would bring Canberra closer to its target of generating 90 per cent of its energy from renewable sources by 2020.

Mr Corbell says it allows the city to embrace a green future.

“It means we can support the development of more solar generation, but also wind generation in the Australian Capital region, and other technologies such as waste to energy technologies,” he said.

“This is all about meeting our greenhouse gas reduction targets and making sure we become a more sustainable city.”
