Reaping nuclear rewards means paying the costs

It was said originally that nuclear-powered electricity would be “too cheap to meter”, but in the current climate it is nuclear’s capacity to deliver secure, low-carbon energy that appeals. We all use…

Blackouts remind us what life was like before cheap, readily available electricity - but it’s time to think about the true price of our power. Candle in the dark image from www.shutterstock.com/Ronen

Save now, pay later: the hidden costs of lower electricity bills

Neighbourhood watch: how to go green and influence people

We all know that children learn by example. I know if I swear in front of my four year old I’m going to hear that word again soon, probably right in front of my mother-in-law, a school teacher, or a priest…
The big emitters of greenhouse gases - China, India, and Brazil - and other developing countries were not bound by Kyoto emission targets, and the USA refused to sign up to the Protocol. Bret Arnett

Kyoto Protocol fails: get ready for a hotter world

Australia is on track at the end of this year to meet its emission reduction target under the Kyoto Protocol. We’ve also signed up to the new version of Kyoto. But that should not encourage us to believe…

Energy White Paper underestimates solar

The 2012 Energy White Paper has much to commend it. In particular, the far greater acknowledgement of the need to shift to clean energy sources is a fundamental shift from previous White Papers. The emphasis…
Do you value this? The Energy White Paper doesn’t. Green MPs

Energy White Paper plans to burn, burn, burn it all

Burn it all. That is the plan in Australia’s new Energy White Paper. Released yesterday by Resources and Energy Minister Martin Ferguson, it talks about responding to climate change while planning the…

Is Origin Smart sleepwalking into a shocking personal data breach?

Early last week, Origin Energy, Australia’s pre-eminent energy retailer, launched an online energy-use monitoring portal Origin Smart to much fanfare. All good – but what about the the privacy and security…

Low-emission’s missing link: reverse auctions for clean power

When it comes to reducing emissions, most serious analysts agree: the market works best, but the market is not enough. The International Energy Agency, the OECD, leading British climate economist Nicholas…
With Australia’s highest carbon intensity, Victoria’s Hazelwood coal-fired power station is a prime candidate to close down part of its generating capacity. AAP

The case for shutting down Hazelwood power station - some facts and figures

Under its Clean Energy Future, the Federal government will negotiate to close 2000 MW of the dirtiest fossil fuel power generating capacity in Australia by 2020. With the price on carbon now in operation…
