A New South Wales Labor government would establish a state-owned renewable energy company to support the rollout of enough renewable energy to power more than three million homes across the state in the next decade.
On Monday the NSW opposition leader, Michael Daley, announced that if elected on 23 March, Labor would deliver seven gigawatts of extra renewable energy by 2030.
The biggest story of the week was probably the Chinese Communist party congress. Leader Xi Jinping is looking to stay for at least another 10 years and putting his “socialist thought” into the party constitution, places him alongside Mao Zedong and Deng Xiaoping in the pantheon of revolutionary leaders. But Richard McGregor says the real star is the party itself, and the West should wake up: Continue reading Saturday salon 28/10→
a revised worst-case sea-level rise scenario of 2.5 metres by 2100, 5.5 metres by 2150 and 9.7 metres by 2200. It says sea level science has “advanced significantly over the last few years, especially (for) land-based ice sheets in Greenland and Antarctica under global warming”, and hence the “correspondingly larger range of possible 21st century rise in sea level than previously thought”.
Most people don’t realise that 64% of the EU’s renewable energy is in fact biomass. The scam starts with UN and EU rules that say if you cut down a tree you don’t count the carbon it emits when you burn it. The assumption is that the tree will grow back again. The New Scientist (probably paywalled) has the story. Continue reading The great EU biomass scam→
A new report suggests that we should be able to feed a growing population, conserve the environment and produce 20% of world energy needs from biomass by making “the best use of agricultural residues, energy crops and waste materials”.
I’m not sure how well they took into account the impact of climate change on agricultural productivity. They did consider an IPCC report on renewable energy (large pdf) and a study by the German Advisory Council on Climate Change (WBGU). Of the latter they said:
The WGBU08 report is arguably the most comprehensive study of the implications of growing bio-energy crops considered here. The approach uses a spatially explicit yield model for terrestrial productivity (LPjmL) driven by IPCC climate models, and scenarios. (p. 35)
You would need to go back to those studies to see what changes of weather, melting glaciers, sea penetration of river deltas etc were taken into account. Continue reading Climate clippings 56→
The US National Oceanic and Atmospheric Administration (NOAA) is predicting a 70 per cent chance of 12 to 18 named storms, six to 10 of which are likely to reach hurricane force – with wind speeds of at least 119 kilometres per hour.
Andrew Garrad, the founder of Garrad Hassan, the world’s largest renewable energy consultancy, has an interesting way of describing Australia’s stop-start renewable energy policy. It goes something like this, in binary code, where nought represents a step backwards, and one represents an advance: 100101100101011010010. The point he’s making is that, more than anything, renewables need consistent policy. And in Australia, and elsewhere in the world, that has been clearly lacking.
The rest of the article is worth reading. Greg Hunt shows what it would be like to have a climate change minister who is interested in climate change.
The Koreans show how to pick winners:
he suspects the future may be dominated by the Korean companies who have become household names in electrical appliances. The likes of Samsung and Hyundai are investing huge sums into clean-tech. “They are going to do things, very fast and well.”
I’ve been on holidays for a bit. Here are some links that I saved from a few hours spent on my daughter’s computer last week by checking some of the usual sources. In the next few days I’ll check the feeds and see whether there are more links to share.
E10 debacle puts the brakes on biofuels in Germany
The real reason, though, was confusion over which car models could use the stuff without harm. Meanwhile a study found that:
up to 69,000 square kilometers (about 27,000 square miles) of forest, pasture and wetlands would have to be cultivated as farmland to satisfy the future demand for biofuel in Europe alone. This is an area twice the size of Belgium. One consequence of such cultivation would be the release of up to 56 million tons of CO2 a year, or the equivalent of the emissions of an additional 12 million to 26 million cars on European roads.
