| Global natural gas boom alone won't slow climate change Posted: 15 Oct 2014 11:28 AM PDT A new analysis of global energy use, economics and the climate shows that expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide. Recent advances in gas production technology based on horizontal drilling and hydraulic fracturing -- also known as fracking -- have led to bountiful, low-cost natural gas. Because gas emits far less carbon dioxide than coal, some researchers have linked the natural gas boom to recent reductions in greenhouse gas emissions in the United States. But could these advanced technologies also have an impact on emissions beyond North America and decades into the future? |
| A brighter design emerges for low-cost, 'greener' LED light bulbs Posted: 15 Oct 2014 08:23 AM PDT The phase-out of traditional incandescent bulbs in the U.S. and elsewhere, as well as a growing interest in energy efficiency, has given light-emitting diode lighting a sales boost. However, that trend could be short-lived as key materials known as rare earth elements become more expensive. Scientists have now designed new materials for making household light-emitting diode bulbs without using these ingredients. |
| A unique approach to monitoring groundwater supplies near Ohio fracking sites Posted: 15 Oct 2014 07:18 AM PDT As fracking expands in Ohio, University of Cincinnati researchers are expanding their testing of private water wells. Hydraulic fracturing, or fracking, involves using millions of gallons of water mixed with sand and chemicals to break up organic-rich shale to release natural gas resources. |
| Power of thorium for improved nuclear design explored by scientists Posted: 14 Oct 2014 05:50 AM PDT The development of a radical new type of nuclear power station that is safer, more cost-effective, compact, quicker and less disruptive to build than any previously constructed is underway. |
