Biofuels tipped to fuel transportation sector by 2050
Posted Thu, 28 Apr 2011 10:59:00 GMT by Lucy BrakeBiofuels 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.

Ukraine marks 25th anniversary of Chernobyl disaster
Posted Tue, 26 Apr 2011 10:58:00 GMT by Laura Brown25 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
Posted Mon, 25 Apr 2011 18:22:01 GMT by Mike CampbellAn 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?
Posted Mon, 25 Apr 2011 08:10:00 GMT by Mike CampbellAt 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
Posted Thu, 21 Apr 2011 18:01:00 GMT by Martin LeggettHydrogen-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.

Nine month pledge to end Japan's nuclear crisis
Posted Wed, 20 Apr 2011 11:07:27 GMT by Laura BrownTepco 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'
Posted Wed, 13 Apr 2011 19:52:00 GMT by Martin LeggettGovernment 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
Posted Wed, 13 Apr 2011 13:05:00 GMT by Martin LeggettA 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.

Confrontations intensify over deep sea oil drilling in New Zealand
Posted Wed, 13 Apr 2011 12:58:00 GMT by Lucy BrakeA 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.

Wind power may have limits - but we don't need to push them
Posted Mon, 11 Apr 2011 17:36:00 GMT by Martin LeggettHeadlines 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?

Algae-Based biofuel may not be economically viable for another 20 years
Posted Wed, 06 Apr 2011 13:02:01 GMT by Kieran BallResearch into algae-based biofuel continues, but some researchers now believe that completing replacing fossil based fuels any time soon in out of the question. Moreover, it would be difficult to produce enough of it to replace diesel.

Shale gas - is this a fracking price worth paying?
Posted Wed, 06 Apr 2011 07:42:00 GMT by Michael EvansShale gas is the last fossil fuel to be exploited. It is relatively clean and relatively cheap, but it's downside is the harm that it can do to the environment. Fracking or hydraulic fracturing may not be a term familiar to everyone, but it is the name given to the process of extracting natural gas from shale.

Will 'Peak Oil' save the planet?
Posted Mon, 04 Apr 2011 22:09:00 GMT by Martin LeggettWith a second oil price spike in three years threatening a fragile world economy, could 'Peak Oil' production be around the corner. And if so, will it help wean us off of polluting-oil use - or usher in a darker dirtier future?

The Japanese nuclear disaster could just be the tip of an iceberg
Posted Mon, 04 Apr 2011 14:12:01 GMT by Michael EvansMore than 10% of the 422 nuclear power stations in the world are located in aeas vulnerable to earthquakes and tsunamis. The Japanese disaster illustrates what could happen. A good example is the ageing Russian-built plant about 18 miles from the Armenian capital of Yerevan.

President Obama Addresses Clean Energy Standard, Dependence On Oil
Posted Thu, 31 Mar 2011 17:34:00 GMT by Kirsten E. SilvenIn an address at Georgetown University, President Barack Obama discussed the need for alternative energy standards and called for a significant reduction in the nation's dependence on foreign oil. Obama noted that there has been progress in the transportation sector, including the increased use of vehicles that are powered by biofuels and natural gas, as well as the auto industry's more efficient production methods involving traditional engines.

After the International Tiger Day, more 'big game' is in trouble. The targeting of elephant in South Africa would bring matters there to a head, as a final solution must be found to this serious lack of conservation success for both rhino and elephant.
International Tiger Day: The remaining 3,200 tigers from 6 sub-species are lucky to be free, but also suffer severely from human interference and frequent attack. It is our job above all to ensure that the distinct tigers are able to breed and reproduce the animals that can survive in their 6 distinct niches. Without help, I'm afraid there is no future whatsoever. The Far East is responsible for huge losses of tigers (elephants, bears, sharks and rhinos, too) and "breeding programs" have to be curtailed when they are obviously simply selling tiger parts. Awareness and ultimate protection will all contribute to a successful defense of these last of the really big cats.
