Jet stream winds show less renewable energy potential

Jet stream winds show less renewable energy potential

Posted Mon, 12 Dec 2011 15:55:18 GMT by Adrian Bishop

High-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

Arizona argument: The impact of renewable energy

Posted Sun, 11 Dec 2011 15:14:00 GMT by Dave Armstrong

Solar 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 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.

Researchers 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 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.

Obtaining 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.

Plants use the sun with brilliant efficiency and scientists are trying to learn how the microscopic systems they use to photosynthesise light could make our own solar power systems more efficient. Scientists are trying to learn better ways to harvest the sun's energy from photosynthesis in plants.

With the use of cells in watches, road signs, buoys and on your local rooftops, the future of the PV (photovoltaic) cell seems assured to be in all of our futures. To utilise the 1KW of energy per m2 that lands on top of us would be a solution to most energy problems.

The Japanese earthquake and tsunami cast new doubt on the safety of nuclear power facilities and, six months, on politicians and scientists are starting to assess the impacts of the biggest nuclear incident since Chernobyl.

A worker was reported to have been killed in an accident at the site of the Marcoule nuclear facility. The incident, which left four other people injured, one seriously, involved a fire and an explosion near a furnace in a radioactive waste storage area, but authorities are stressing that there has been no release of radiation to the environment at this stage.

Drought-stricken Texas is looking to manage water use at hydrofracking operations, but current law is flawed: operators using wells for hydrofracking are exempt from water use reporting requirements. Water utilities and regulators have put restrictions on residential, commercial, and agricultural water use, and now they are turning to fracking.

A new material could be the answer to the current maxing out of wind turbine size caused by blade weight. A university researcher has found a new material to make lighter blades that are eight times tougher than the current best.

While some grasses may produce a good return in biofuel production, the amount of water they drink could make them unsuitable and costly in many conditions. A University of Illinois study carried out a detailed analysis effects on water supplies associated with growing miscanthus and switchgrass which have been tipped as a possible alternative to corn as a biofuel crop.

Does the panda hold a key to the greenest biofuels?

Does the panda hold a key to the greenest biofuels?

Bacteria lurking in the gut of bamboo-chomping pandas may help 'cellulosic biofuels' to leap a major hurdle for their wider use. Analysis of panda poop, presented at this week's ACS meeting, has shown that enzymes from the bacteria are excellent at digesting the cellulose in grasses, woods and stalks - and at everyday conditions, potentially opening the door for new biofuels that don't compete for land with crops for food.
