Although Donald Trump has called climate change a hoax invented by China, Chinese leaders believe cutting carbon emissions will generate economic and political payoffs at home and abroad.
Individual light-harvesting protein complexes have a remarkable ability. Light, which is normally effectively harvested, is also used to finely control how much of it should be harvested.
The government in Delhi must be more ambitious. Current plans for more renewable energy plants are just a tenth of what is needed.
Air pollution from burning firewood and charcoal is the fourth-biggest killer in many countries.
An open letter from 190 solar energy researchers in defence of the Australian Renewable Energy Agency, which has funded world-leading research.
The Australian Renewable Energy Agency is facing a $1.3 billion budget chop as part of the federal government's savings measures. But sacrifice the lead agency for green energy development
Critics don't think Tesla can sell enough home batteries to justify its acquisition of SolarCity, but what they're underestimating is the potential for innovation the Gigafactory brings.
There's a wider trend towards linking the energy and climate portfolios, and not before time – the race is on towards a low-carbon economy, and joined-up policy gets faster results.
These countries are well-positioned to lead the way from fossil fuels to low-carbon energy.
There are several areas where Australia could be a world leader in innovation. If we can identify them and focus our efforts there, we could generate some genuine benefits here and abroad.
The Coalition has asked CSIRO to develop a "roadmap" towards commercialised clean energy. It's a good idea as long as the plan is clear, and there's enough money behind it.
Britain's future could be bright – but first the grid needs a major upgrade.
When will residential solar be cheaper than the cost of power from the grid? This point of 'grid parity' is a moving target but moving closer in a number of places.
Energy Minister Josh Frydenberg told Q&A that Australia has the highest number of solar panels on people's roofs per capita anywhere in the world. Is that right?
The airline industry's promised technological solutions have not arrived, and they never will.
Clean energy in Africa is certainly a possibility despite those in the fossil fuel industry believing this not to be true.
Our civilisation is built on chemistry, and the science has a bright future, with the launch of a new Decadal Plan that will steer the science into the future.
If you're worried about rising electricity prices, then going off-grid sounds attractive. But why not create an intelligent network of solar-powerd batteries that can reduce prices for all?
Internet connections could one day come from solar-powered planes that fly for months or even longer at a time.
Utilities are pushing back against the spread of rooftop solar power and charging bigger fees to solar homes. Who is right in this solar-versus-utilities fight?
