Oyster wave power devices approved in Scotland
Posted Tue, 14 Feb 2012 16:43:23 GMT by Adrian BishopApproval has been given to test the first array of nearshore wave power units in Orkney that could power more than 1,000 homes. Two new Oyster wave converters will join a similar unit at Orkney's European Marine Energy Centre and connected to the onshore hydroelectric plant.

Shale gas, the 'clean bridge' to nowhere?
Posted Mon, 06 Feb 2012 15:11:00 GMT by Martin LeggettThe boom in shale gas production has left US gas prices near record lows. But those low prices are threatening the switch to no-carbon renewables, like wind and solar, as utilities switch to gas in preference. Many are worrying that the shale gas boom is a dangerous distraction, as reserves forecasts are slashed.

Jet stream winds show less renewable energy potential
Posted Mon, 12 Dec 2011 15:55:18 GMT by Adrian BishopHigh-speed jet stream winds in the upper atmosphere would produce 200-times less renewable energy than previously thought and wreak havock on the climate and weather, German scientists claim.

Arizona argument: The impact of renewable energy
Posted Sun, 11 Dec 2011 15:14:00 GMT by Dave ArmstrongSolar power and the Arizona desert is a good fit, with the highest radiation in North America, as shown in this map. Hundreds of thousands of hectares will be affected soon by the construction of photovoltaic power generators and various offsite effects. These basic effects of renewable energy are listed as habitat fragmentation, dust creation, pollution by varied chemicals and heat and light generation.

Scaling Down Ambitions on Renewable Energy Not Cost Effective
Posted Tue, 08 Nov 2011 20:52:01 GMT by Angela MunroScaling down on renewable energy ambitions could cost more in the long term according to the Positive Energy report by WWF-UK. This is contrary to KPMG's beliefs that scaling down renewable energy ambitions could save the economy £34 billion within the next ten years.

'Greener' hybrid power plants proposed
Posted Fri, 04 Nov 2011 19:28:00 GMT by Adrian BishopA cost-effective and environmentally friendly way to run power plants has been proposed by Israeli scientists. The hybrid alternative, Professor Kribus has devised a new steam-injection gas turbine method that employs both fuel and steam from solar power.

Aluminium alloy allows affordable hydrogen storage
Posted Tue, 01 Nov 2011 16:11:00 GMT by Dave CollierResearchers have demonstrated that it is possible to use an affordable alloy as a catalyst for the generation of atomic hydrogen. Hydrogen is a fuel that is abundant and non-polluting and would be the perfect alternative to the environmentally-damaging fossil fuels that are in use today.

California aims for 'Solarfornia'
Posted Tue, 25 Oct 2011 18:16:00 GMT by Dave ArmstrongCalifornia is very ambitious about its 33% renewable energy aim for 2020 (after a 20% objective for 2010). Governor Jerry Brown calls for 8,000 megawatts from various large-scalewind and solar installations. The idea of a large state like California as a world leader in energy development appeals to those who want to promote more employment, new industries and technological leadership.

Forest fuel may need rethinking
Posted Mon, 24 Oct 2011 13:24:00 GMT by Dave CollierObtaining biofuel from forests has been shown to increase carbon emissions. Biofuel production is not without controversy; the food or fuel debate cannot be avoided in developing countries and the impact on water resources is unavoidable. The drive to find alternatives to fossil fuels has caused as many arguments as it has found solutions.

Biodiversity is the term given to the variety of life on Earth and the natural pattern it forms. The biodiversity we see today is the result of millions of years of evolution, initially shaped by natural processes, but in modern times increasingly as a result of human intervention. We are an integral part of the web of biodiversity and we depend on this web, as does every other life form on the planet.
