Coal closures announced this week in South Australia will cause employment pain, but could also help pave the way for the state to go 100% renewable - something that modelling suggests is eminently possible.
South Africa has won global recognition for its renewable energy programme, but will it succeed in balancing the demands of financial and commercial soundness, and the transformation agenda?
Instead of spending time trying to make nuclear energy a possibility, South Africa should look to forms of renewable energy instead.
G7 leaders have pledged to help end the world’s fossil fuel use by the end of the century. It’s a laudable aim, but decarbonisation can and should be done by the middle, not the end, of this century.
What if you could grow biofuels on land nobody wants, using just seawater and sunlight, and produce food at the same time?
There’s no point promoting renewable technology if all the power still resides with fossil fuel firms.
The Grattan Institute has reported that the costs of solar panels have outweighed the benefits by almost A$10 billion in Australia. But the real benefits of cutting greenhouse emissions are much larger.
While Australia has reached a deal on the Renewable Energy Target, there’s no long-term certainty for the sector yet.
Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
With the federal cuts to the renewable energy target, the states are stepping up to fill the gap.
Nobel Laureates met recently in Hong Kong to sign a memorandum calling for cities to help guard against climate change. As the most creative places on the planet, big cities are the perfect place to meet this challenge.
We cannot eliminate the inherent risks of nuclear power but it is rigorously monitored and has a proven performance of delivering zero-carbon electricity.
Contrary to economic theory, data shows that the latest drop in energy prices does not undermine investment in renewable energy.
Despite solid results from the first emissions reduction fund auction, Australia hasn’t yet got a climate policy to last.
The unveiling of Tesla’s Powerwall home battery has been hailed as a huge moment in renewable energy. But don’t forget the other innovations that can help you use that stored power more efficiently.
Tesla’s new home battery could help halve the costs of electricity for typical American households - all using existing technology. The fossil fuel industry is right to be worried.
The SNP wants the UK to match Scotland’s commitments to carbon reduction.
Lib Dem energy minister Ed Davey says renewable electricity has soared under the coalition. Is he right?
Plaid looks left as energy manifesto fuels talk of a Green-SNP alliance.
