There is no doubt we need to stop emitting fossil carbon. But if we fixate on replacing fossil fuels with renewable energy and don’t also reduce consumption and energy waste, we risk failure.

Some Australian states have committed to 100% renewable energy targets, or even 200% renewable energy targets. But this doesn’t mean their electricity is, or will be, emissions free.
None of Australia’s highest-emitting energy firms are fully or even closely aligned with global climate goals. Just one goes even partway, and five appeared to be taking no action at all.
As global oil consumption drops, oil companies are pivoting to petrochemicals, and could crowd out bio-based alternatives.
The opportunity won’t last forever. Countries that move first will gain an advantage in new industries, technologies and export markets. Those that wait may never catch up.
New research found lots of incentives to chuck out working solar panels and replace them with new ones. This may be creating huge amounts of unnecessary waste.
The seismic changes to energy supply and demand during the pandemic could be just the beginning.
The maintenance required for renewable tech like windfarms can harm the environment. Robots are helping solve that.
Natural gas may still be cheaper than electricity in some cases, but the price of gas is likely to rise if New Zealand follows the Climate Change Commission’s advice to shift to electrification.
The ocean moderates climate change by absorbing CO₂ emissions, hosts valuable biodiversity and provides food to millions, but all of these services are threatened by pollution and human activities.
The Biden administration has a goal of getting from today’s 42 megawatts of offshore wind power to nearly 30,000 by the end of the decade, but there are still obstacles ahead.
The new commitments of state governments go some way to filling the void left by the lack of a national climate policy. The states should, and can, coordinate their efforts. Here’s how.
Installing solar panels over California’s 4,000 miles of canals could generate less expensive, renewable energy, save water, fight climate change – and offer a solution for the thirsty American West.
A proposal to change the way electricity generators and retailers strike contracts for electricity would be bad for both consumers and climate action.
The socio-economic and political factors that keep conventional energy out of reach of the poor can do the same with renewable energy.
Prime Minister Scott Morrison has announced next month’s budget will include a further $539.2 million government investment in new clean hydrogen and carbon capture, use and storage projects.
The genius of the Paris climate agreement was getting major oil producing countries to agree to a target, but they still have widely different views of energy’s future.
Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.
Ethiopia, Sudan, Egypt and their neighbours could deploy large-scale solar and wind farms, connected by a regionally integrated power grid.
Rare-earth metals are currently mined or recovered via e-waste recycling — methods with drawbacks including high cost, environmental damage, and risks to human safety. This is where we come in.
