Labor wants 50% of Australia’s electricity to come from renewables by 2030 - but what about other climate policies? Lawrence Murray/Flickr

Labor embraces renewables at the cost of good climate policy

Labor's proposal for 50% renewables demonstrates in spades how poisonous climate change politics has trumped good policy.

Bioenergy: making money, and clean energy

The government has issued a draft direction to the Clean Energy Finance Corporation to invest in "emerging" clean energy such as bioenergy. But what are the prospects for bioenergy?

The Clean Energy Finance Corporation is meant to back winners, not minnows

Environment minister Greg Hunt wants the Clean Energy Finance Corporation to focus on new technologies, not wind and solar. But that's not what it was set up to do, and Australia already has an agency for that.

How South Africa can transition to a less energy-intensive economy

Shifting South Africa's economy from energy intensive sectors to those with lower energy consumption will take more time, and even more funding. But the impact will be more permanent and sustainable.

Australia can stop greenhouse gas emissions by 2050: here’s how

To avoid dangerous climate change there is a finite amount of greenhouse gas emissions, in particular CO<sub>2</sub>, that we can add to the atmosphere - our global carbon budget. If we use our budget wisely, we have until about 2050 to transition to zero net emissions. But how do we get there?

Solar fuels: how planes and cars could be powered by the sun

Rooftop solar power is exploding in the US but some scientists are pursuing a radically different route in renewable energy: storing solar energy as a liquid fuel.

How much does wind energy cost? Debunking the myths

Wind energy is already competitive with fossil fuels, will reduce electricity prices for consumers, and will play a large role in reducing Australia's greenhouse gas emissions.

More research is good, but not if wind experts are told what to find

"More research needed" is a familiar cry in science. But in the case of the Senate's call for yet more scrutiny of wind farms, there are signs that experts are being ushered in a preconceived direction.
