The US is gradually shifting to lower-carbon energy sources, but the COVID-19 pandemic, an oil price crash and a likely recession are big speed bumps.
New lightweight, efficient and ultra-thin solar technologies show promise, but it may be too soon to abandon conventional solar photovoltaics.
For the next couple of decades, Snowy 2.0 will in fact store coal-fired electricity, not renewable electricity.
Here's how spinning metal can smooth out the spikes in renewable electricity generation.
Teck Resources' decision to cancel its oilsands project is a blow to Trudeau's government.
Sun Cable could provide Australia an alternative to the export business of coal and gas, and even reduce our export dependence on China.
Pumped thermal electricity storage turns electricity into heat and back again – which can compensate for the intermittent supply of renewables.
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 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.
Britain greets a new decade with substantially cleaner electricity, but challenges lie ahead to decarbonise its transport and heating.
We asked some climate researchers what kept them hopeful in 2019.
After a decade of rising electricity bills, prices are projected to fall thanks to new renewable generation.
A revolution in ownership must be at the heart of a Green New Deal.
Coal and gas have been proposed as a way to make 'clean' hydrogen. But that road is full of challenges.
