Evolving more efficient wind farms

Evolving more efficient wind farms

Posted Thu, 05 May 2011 19:04:00 GMT by Mike Campbell

Dr Frank Neumann of the School of Computer Science at the University of Adelaide is using this approach to determine the best placement of turbines on a wind farm to enhance their productivity. The project involves collaboration with researchers at the Massachusetts Institute of Technology.

New York Looks to Landfill for Renewable Energy

Posted Tue, 03 May 2011 21:54:00 GMT by Kieran Ball

Are 'brownfield' sites the renewable power generators of tomorrow? Landfill, disused mines, redundant industrial sites and even rooftops are all starting to look like attractive locations for renewable energies generators such as solar power, wind turbines and even biomass production. All we need is the commitment from business and government to put them to good use.

US wind power strategy won't be stymied by warming climate

US wind power strategy won't be stymied by warming climate

Global warming is unlikely to suck the power out of a US wind farm energy solution. That's the good news to come from a paper in this weeks Proceedings of the National Academy of Sciences, which projects strengthening winds in many areas slated for wind farms. The paper helps to fill in a worrying blank on the possible knock-ons to renewables due to climate change.

Google's drive to make renewable energy cheaper than coal power energy is a long term mission. Since launching the initiative, Google has cut investment in renewable energy technology companies while increasing investment in renewable power generation schemes, most notably with a recent $100 million investment in the world's largest wind farm in Oregon, US.

The authors of a new report from Berkeley Lab may paint a rosy picture of China's future emissions, seeing them as peaking much earlier than other analysts - but sadly it may still be too little, too late, unless we all take our foot off of the global gas pedal.

Biofuels tipped to fuel transportation sector by 2050

Biofuels tipped to fuel transportation sector by 2050

Biofuels are predicted to be supplying over a quarter of the world's transport fuel market by the year 2050. As the world struggles with rising petrol and diesel costs, biofuels are increasingly being seen as the most viable alternative source. However, this will come at a cost.

25 years on, the world remembers history's worst nuclear disaster. Just after midnight on 26 April 1986, the Chernobyl nuclear power plant, just 60 miles north of the Ukrainian capital Kiev, exploded. Over 350,000 people were evacuated. It was, and remains, the world's worst nuclear disaster.

Green Energy From Estuaries

Green Energy From Estuaries

Posted Mon, 25 Apr 2011 18:22:01 GMT by Mike Campbell

An estuary is defined as being the mixing zone where fresh river water meets the salt water of the ocean. The penetration of salt water into the fresh river water can extend backwards from the coast for some distance. Researchers at Stanford University recently published details of a battery which uses changes in salinity to produce electricity (see Nano Lett., 2011, 11 (4), pp 1810-1813).

Fukushima: A Rush to Nuclear Energy Judgment?

Fukushima: A Rush to Nuclear Energy Judgment?

Posted Mon, 25 Apr 2011 08:10:00 GMT by Mike Campbell

At the start of this piece, let me nail my colours to the mast: I am a proponent of nuclear energy and I have worked on the periphery of the nuclear industry. What has slowly emerged since a devastating 9.0 magnitude earthquake and ensuing tsunami hit north east Japan on the 11th of March has served to show how ignorant the world is about radioactivity and risk.

Hydrogen fuel-cells get a boost with a cheap catalyst makeover

Hydrogen-powered cars, laptops and mobiles could be a step closer, thanks to the discovery of a practical - and cheap - alternative to sky-high priced platinum. Platinum is currently the best catalyst for hydrogen fuel-cells. But the new carbon-iron-cobalt catalyst, described in today's Science, works as well as platinum, and its low cost could pull hydrogen power out of the shadows into a brighter renewable future.

Tepco puts a roadmap in place to end the crisis at the Fukushima nuclear plant by the end of the year.The operators of Japan's stricken Fukushima nuclear plant are implementing a nine month roadmap, ensuring the crisis will be resolved by the end of 2011. Fresh concerns were raised last week when, on Friday, levels of radiation in the sea near reactor 2 were measured to be 6,500 times the legal limit.

Ethical impact of biofuels bonanza has 'backfired badly'

Ethical impact of biofuels bonanza has 'backfired badly'

Government policies that have pushed biofuels as part of the move to a greener transport system, have often pushed ethical concerns, for indigenous peoples, to one side. So says a new report from the Nuffield Council on Bioethics, on the ethical impact of the rush to biofuels. An internationally agreed ethical certification scheme is the way forward, say the authors.

Shale-gas 'worse than coal' for total life-cycle emissions

Shale-gas 'worse than coal' for total life-cycle emissions

A new study on the total climate-impact of fossil fuels shows that natural gas is more dangerous to the planet than coal - but that top of the roost for climate-change causing fuels may well be shale gas. This massive new energy resource, being aggressively exploited across the US, has been slated for the waste-water pollution contamination from 'fracking'. Now its image as a 'clean' transitional fuel is in doubt too.

A flotilla of vessels opposing the surveying for deep sea oil has been ordered to stay away by the New Zealand Police. Activists in the Ruakumara Basin off the East Cape of New Zealand were able to stop the seismic survey vessel Orient Explorer from carrying out its work by swimming in front of it.

Headlines that wind power may not be renewable have quickly been scotched - with New Scientist changing its title for the provocative piece. It looked at a paper on how renewable energy production stacked up against the amount of 'free energy' the earth has at its disposal. But do we really need to claim such massive shares of the earth's energy bounty that those limits become a concern?
