By Dénes Csala, Lancaster University and Sgouris Sgouridis, Masdar Institute Most of the world could switch to 100% renewable energy by 2050, creating millions of jobs, saving millions of lives that would otherwise be lost to air pollution, and avoiding 1.5℃ of warming. That’s the bold claim of a major new study by Stanford professor Mark … Read More

By Andrew Blakers, Australian National University Solar has become the world’s favourite new type of electricity generation, according to global data showing that more solar photovoltaic (PV) capacity is being installed than any other generation technology. Worldwide, some 73 gigawatts of net new solar PV capacity was installed in 2016. Wind energy came in second place (55GW), … Read More

By George Jones Whenever electricity is taken from one place to another, some of it is lost, ultimately as heat. In New Zealand, this waste electricity constitutes about 6 or 7 percent of the electricity generated; enough to power the entire Greater Wellington area. In other countries it is usually larger, up to three or four times NZ’s percentage. The industry … Read More

We’re running a bit late with this one: recorded last week before the big wind left Gareth powerless for six days (a bit like Glenn’s PC), John Cook ruminates on the result of the Australian election, the boys marvel at the Mail’s myth making about Arctic sea ice, and look forward to the release of […] … Read More

At long last: John Cook from Skeptical Science rejoins the Climate Show team for the first show of 2013. He hooks up with Glenn and Gareth to review Australia’s big heatwave, and stays around to dig into the new Greenpeace report on dirty energy, discuss Obama’s inauguration speech and Boris Johnson’s climate blunder, the latest [...] … Read More

There is an interesting article in the 28th February New Scientist called “How clean is green?” which takes a look at climate change and our options for alternative sources of energy to fossil fuel. By considering the links between different sources of alternative energy and the heat they generate the article comes to the conclusion that harnessing solar energy … Read More

If you watch nothing else today, take the time to look at this spectacular movie of an aurora australis taken by the International Space Station on September 17, and made available by NASA’s Earth Observatory a couple of days ago. Not really climate-related, unless you’re into solar/climate linkages, but posted because the images are spectacular. [...] … Read More

"Surfer" waves on the solar surface Yet another [1] gorgeous picture from NASA’s Solar Dynamic Observatory – this one capturing some serious waves on the outer surface of the sun. These are almost identical to earth-based surfing waves, well apart from the fact that they are the size of the USA and are composed of … Read More
