Ross Garnaut: China to reach ‘peak coal’ for electricity by 2015

China’s use of coal for electricity could peak as early as next year, then decline until 2020 in a turnaround of “global importance”, according to economist Ross Garnaut in a lecture presented at the Melbourne…
The cat that got too fat. But let’s talk about you. Yukari

Ten things you didn’t know about fat

Our understanding of fats – including which ones are actually good for us – is evolving. We know for example that red meat and meat products, cakes and biscuits, which are rich sources of saturated fatty…

Small nuclear reactors may be the key to a low-carbon future

Take a hard look at the painful process of de-carbonising the UK’s electricity supply, and it’s clear that the options on the table are not great. From the outset, changes to the system generate further…
You spin me right round, and power the lights too. Simon Syon

Relying on renewables need not mean dealing with blackouts

For all the huge, hulking buildings of concrete and steel that house coal, gas or nuclear power stations, or towering 100-metre-tall wind turbines, generating electricity is in fact a very precise and…

Russia’s game of chicken with Ukraine leaves Europe on the edge

As with the previous Russia-Ukraine gas disputes in 2006 and 2009, how we describe the current stand-off between the two countries is a matter of semantics. Those earlier disputes found solutions based…

Human urine: a wee energy producer?

Carbon from dried human urine has been extracted for use in chemical fuel cells. These cells traditionally use platinum as…

Japan’s quest to tap the natural gas beneath the ocean floor

Last year Japanese scientists announced they had for the first time extracted gas from offshore deposits of methane hydrate, an ice-like substance made of natural gas (methane) trapped inside water crystals…

Fracking will be tried in the court of public opinion in 2015

There has been an anxious search for new sources of fossil fuels, and shale gas appears to offer Britain a key national resource. But the nation’s new-found hydrocarbon wealth has met with far from universal…

Calling people NIMBYs won’t stop development arguments

From coal seam gas to wind farms, new resource projects seem to be pitting communities against corporations, and people against their neighbours. We often see, in such cases, community concerns labelled…
Better appliances and energy-efficiency rules saved Australians more than A$3 billion on electricity last year alone. Shutterstock

Energy-smart appliances cut Australian power bills by billions

The latest review of Australia’s energy-saving appliance scheme has delivered a rare trifecta: a good news story for the economy, the community and the environment. According to my estimates from data…
