To shift away from fossil fuels, we need to copy plants

Most of the energy that fuels our lives comes from plants. Whether it is a fossil fuel that was formed hundreds of millions of years ago or the food we eat, all carbon-borne energy has its ultimate origins…

Australia can get to zero carbon emissions, and grow the economy

Today more than 120 world leaders are gathered in New York for the Climate Leaders’ Summit. With global emissions continuing to rise, it is easy to be pessimistic. But new research released today shows…

CSIRO risks backing the wrong horse as it reacts to budget cuts

What happens to CSIRO when the federal government decides to strip away A$111 million over four years from its A$733 million annual contribution to the organisation’s budget? We are beginning to find out…

Litany of deep cuts for environmental programs

Budgets are often framed as give and take. But in the case of the environment, the government is taking large amounts of money in cuts, while giving little back beyond funding the Direct Action climate…

Seawater could be new fuel for navy ships

Seawater could be used to fuel naval ships, replacing the need for oil-based jet fuel. Using metal catalytic converters in…

Mixed fuels, mixed messages: the motivations for ethanol expansion

In the lead up to the federal election, Queensland mining magnate Clive Palmer called for an increase in the number of vehicles using ethanol-based fuels, as a way of reducing Australia’s greenhouse emissions…

Farmers could use land to create power as well as food

One of Britain’s largest independent cheese producers, Wyke Farms in Somerset, picked up a commendation in the BusinessGreen Leaders awards this month for its efforts to become completely energy self-sufficient…
Whether more power stations should switch to burning wood or biomass is debatable. David Cheskin/PA

If we burn wood for energy, we can’t have our cake and eat it

Many countries have turned to the planet’s forests to meet their need for renewable energy, burning wood chips and pellets produced at home or abroad in power stations to generate electricity. But a report…

It stinks, but food waste is feeding our hunger for energy

The amount of scrap food thrown away worldwide is staggering. WRAP, a government-funded non-profit set up to encourage recycling and clamp down on waste, reports that in the UK we discard more than 7.2m…

Termite stomach acid to aid biofuel

A study into the role of gut bacteria in termite stomachs has given surprising, but hopeful, results. Researchers at Purdue…

Bacteria boosts biofuel production

A new biofuel production process using microbes to manufacture biofuel and hydrogen, all while consuming agricultural wastes…
Researchers hope to create implanted medical devices, like pacemakers, that can be powered with glucose. Flickr

Powered by sugar: scientists report glucose biofuel cell breakthrough

Scientists have created a glucose-powered biofuel cell that is five to 10 times more powerful than existing cells and lasts weeks longer, paving the way for implanted medical devices that run on the body’s…
