More than ten offshore wind farms are currently proposed for Australia. If built, their combined capacity would be greater than all coal-fired power plants in the nation.
Colonialism, political turmoil and unmet citizen promises all lie behind the rise of attacks on foreign-run fossil fuel plants in Mozambique.
Hydrogen could replace fossil fuels, but it's only as clean as the techniques used to produce it. Almost all production comes from high-carbon sources, but new investments could change that.
India is expected to overtake China this decade as the world’s most populous nation. That puts it at the heart of the global challenge to beat climate change.
Some of the most powerful offshore wind is over water too deep for a standard wind turbine. Engineers found a way around the problem.
Hybrid energy systems that combine renewable and non-renewable fuel systems could be the key to sub-Saharan Africa's energy transition.
How do we ensure solutions to climate change doesn't make biodiversity loss worse? Fifty of the world's leading researchers on biodiversity and climate have sought to answer this question.
A complete switch to biofuels is neither feasible nor desirable, but they could replace some fossil fuels in transport and heating. If biofuels are produced from waste products, that's even better.
Contracts for exploring the deep sea are due to expire before a safe mining code can be agreed.
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℃ 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.
