Wind power may have limits - but we don't need to push them

Wind power may have limits - but we don't need to push them

Posted Mon, 11 Apr 2011 17:36:00 GMT by Martin Leggett

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?

Algae-Based biofuel may not be economically viable for another 20 years

Algae-Based biofuel may not be economically viable for another 20 years

Research 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 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.

With 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?

More 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.

In 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.

A new frontier in clean electricity generation, from the natural mixing of fresh river and salty sea waters, has moved closer with research published by Stanford University scientists. These eco-batteries could ultimately supply up to 13% of global electricity - once researchers can solve practical and conservation issues of deploying them in river mouths.

The Clean Energy race is on, according to a report from the PEW Environment group, with a record $240 billion invested in renewable energy sources in 2010. Leading the transformation are those with strong support for the greening of energy - including China, Italy and Germany. Uncertainty has left others, like the US and UK, further behind.

Artificial leaves, which mimic photosynthesis in plants, could potentially generate electricity for poor households. At the 241st meeting of the American Chemical Society in Anaheim on the 27th of March, 2011, scientists presented what well may turn out to be a breakthrough development: the first practically usable artificial leaf.

50 percent of people disapprove with building more nuclear power plants, compared with 21 percent in 1977, a CBS news poll has found. The pros and cons of nuclear power are hotly debated by many diverse groups. On one hand, there is the pro-nuclear camp, which believes that nuclear power is the future of our energy

A new certification system will show consumers that the biofuels they use have been produced sustainably and with social responsibility says a producers group. The RSB Certification System was unveiled yesterday at the World Biofuels Markets 2011 in Rotterdam, promising to give producers a way into highly regulated markets like the European Union.

Water Security Risk Index show more oil producing countries rated 'extreme risk'. The danger is that disruption to water supplies could, in turn, lead to higher oil prices, as high volumes of water are needed in the oil production process. Huge quantities of 'lift water' are often used to force oil from wells with insufficient geological pressure to bring the oil to the surface

Hydraulic fracturing or fracking for shale gas is the new wild frontier of the fossil-fuel industry, one they're keen to promote as a low-carbon alternative to high-polluting coal and oil. Environmentalists are worried, though, about contaminated drinking water, and earth tremors - but perhaps those are the least of the dangers.

Ten underwater turbines to lead technology research in exciting project. The Scottish Government has backed a plan to build 10 one-megawatt tidal power turbines in a strait between the small islands of Islay (pronounced ''Isla'') and Jura off the West coast of Scotland. This will be the world's largest tidal power station - which resembles a wind farm, only underwater!
