Internet connections could one day come from solar-powered planes that fly for months or even longer at a time.
The 'early adopters' of home battery storage will pay significantly more than those who come later, but it won't be long until prices drop enough for many more to get on board.
Dr Alan Finkel took over as Australia's Chief Scientist in January this year. In this exclusive interview, he describes his approach to science, and to issues such as renewable energy and STEM jobs.
Research and development is critical if South Africa wants to effectively increase its renewable energy output.
'Energy productivity' is the new buzz-phrase in energy and climate policy, what even is it?
The U.S. could dramatically increase solar and wind power without expensive energy storage. The key is to overlay high-voltage direct current power lines on our system of regional grids.
Investment is key if Nigeria is to improve on providing adequate energy to the people.
The wind and solar industries scored a huge win by getting extended tax credits, but research shows this isn't the best policy for lowering emissions through renewable energy.
Under the Paris climate agreement, Australia has stated that it will reduce greenhouse gas emissions by 26-28% by 2030 compared to 2005 levels. How will we achieve this?
Despite its vital role in the development of Australia's economy, the future of coal looks grim in a world aiming to limit warming to below 2℃.
The Paris Agreement will leave activists demanding direct action on fossil fuels and energy market reform.
Updated forecasts from CSIRO suggest electricity prices will continue to rise as more renewable energy enters the grid.
Pedalling our televisions could save us a fortune in electricity – and keep us in great shape, too.
Can Australians be sustainable and enjoy endless economic growth? It's not likely
South Africa has been slow to adopt renewable energy sources. One option, which has proved successful elsewhere, would be to install solar photovoltaic panels on rooftops in low-income areas.
By 2030 renewable energy sources such as solar and wind will cost a similar amount to fossils fuels such as coal and gas, thanks to falling technology costs
Much of India's huge population is still without electricity, perhaps making climate action a tough sell. But India's vision for green development chimes well with the world's climate agenda.
UK's decision to close coal power plants is really a statement of the obvious, and does nothing to answer the problem of what to do afterwards.
The Greens have backed a renewable energy goal of 90% by 2030. With wind and solar getting cheaper all the time, it's an achievable challenge.
What have businesses put on the table ahead of the Paris climate summit in December?
