The world runs on energy, so finding low-emission alternatives to fossil fuels is crucial. Wind and solar are cheap and abundant but can't do everything. But hydrogen fuel could complete the picture.
The global warming potential of different greenhouse gases is often poorly understood, distorting which are the biggest concern.
Social tipping interventions have the potential to pave the way for rapid change and avert climate change.
The mainstream news media has been biased in its reporting and portrayal of Indigenous Peoples on stories about renewable energy projects. What and how can they do better?
The deluge of opinions and proposed solutions to South Africa's energy crisis reflects corporate and political interests.
Plans to reduce emissions quickly are seductive but can stall. Climate initiatives should end dependence on fossil energy and pursue a path towards a more just and equitable society.
A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world's solar power.
A new technology for rechargeable batteries overcomes many of the problems with the ones we use today.

Coal and gas have been proposed as a way to make 'clean' hydrogen. But that road is full of challenges.
Just 1kg of hydrogen can power a split-cycle air conditioner for 14.5 hours. The possibilities are endless - and now we have a plan to get there.
As the effects of climate change become clearer and more ominous, fossil fuel companies face a choice: Defy warnings of catastrophic climate change, or envision their roles in a post-carbon world.
Biodiversity, public transport and home insulation loom large in Labour's flagship programme for green governance.
The most vulnerable people bear the brunt of an ineffective energy system that prioritises profit over the consumer.
Living sustainably has its challenges, but none greater than in the climate and geography of Antarctica.
Don't expect the new technology to become solar's dark twin just yet, but it could play an important role in energy demands of the future.
The US President pledged ambitious growth in the fossil fuel industry on his 2016 campaign trail – but new data shows that the green economy was already growing almost three times as fast.
