A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world's solar power.
Nuclear power isn't needed to meet Ontario’s electricity needs. And the absence of nuclear power won't have any impact on emissions in Ontario's energy sector.
Solar cells make electricity directly from sunlight, but how do they do it?
Long before Apple vs. Microsoft or Facebook vs. Google, there was Edison vs. Westinghouse.
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.
Tapping just 3.7% of solar potential in countries in China's intercontinental infrastructure programme could power the entire region.
Australia is installing renewable energy at more than ten times the global average. This is excellent news, but raises serious questions about integrating this electricity into our grids.
The design of the global money game is the real antagonist in the fight against climate change. But the call to arms tends to be directed at the players who have had best luck with the dice.
The federal government this week heralded Australia's renewable energy performance. But the outlook leaves little cause for celebration.
We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
An eight year study of half hourly prices finds that wind and solar generation have been pushing wholesale electricity prices down.
Zimbabwe has a severe energy crisis because its major sources of electricity are struggling to keep up with demand.
Japan's global influence has waned in recent years. Showing that renewables can decouple emissions from economic success could help the country find its niche and spark a race to power the Earth.
A legacy in fossil fuels is likely to help even in the era of renewable energy.
The vast desert could potentially produce more than seven times the electricity requirements of Europe, with almost no carbon emissions.
Twelve power projects are in the running for federal government dollars: six pumped hydro, five gas and one coal. It's clear which one shouldn't be on the list, for economic and environmental reasons.
Climate justice policies could potentially double as tools of colonialism that harm people outside the US.
But many new governors and members of Congress intend to take action on climate change.
South Africa's sunshine and coastlines are ideal for renewable energy generation but the country's struggling to take advantage of this.
There are some good explanations for the mismatch between regional support for climate action and the areas where renewable energy is making the biggest inroads.
