Heat pumps are the technology of choice for heating and cooling buildings more efficiently and with fewer carbon emissions than furnaces and air conditioning.
Keeping global warming under 1.5°C is still achievable with rapid deployment of renewables. A new report found solar and wind can supply the world’s energy demand more than 50 times over.
If shipping were a country, it would rank between Japan and Germany as the sixth-largest contributor to global carbon dioxide emissions.
Addressing inefficiencies in Ghana’s electricity sector will reduce the need to price in distribution losses
How much energy does the internet use, and - given recent technological advances - could it ever run on renewable energy alone?
Rather than considering the job done, Tasmania should seize opportunities including renewable energy, net-zero industrial exports and forest preservation.
Ocean waves are a massive source of energy, but it’s challenging to design power generators for the harsh environment. Allowing marine organisms to grow on engineered structures could help.
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.
