Shale gas, the 'clean bridge' to nowhere?

Shale gas, the 'clean bridge' to nowhere?

Posted Mon, 06 Feb 2012 15:11:00 GMT by Martin Leggett

The 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.

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.

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.
