This is bad.
A step in the right direction.
Princeton University researchers have uncovered a previously unknown and potentially substantial source of methane emissions: abandoned oil and gas wells. After analyzing wells from Pennsylvania, they found that a worrying amount of them leaked significant quantities of the greenhouse gas. A previous Stanford study estimated about 3 million abandoned wells in the United States alone, so if these wells are indeed leaking
A trio of newly published studies showed once again that natural gas is not a clean energy bridge – the studies highlighting the various problems associated with natural gas. Firstly, it was shown that emissions databases underestimate the methane released from fossil-fuel extraction in the U.S. Southwest. “A global gas boom is not a replacement for energy and climate policies,” write
Given the shale boom, the United States has now become the world’s leading natural gas producer. Because it only releases 50% as much emissions for the same equivalent amount of energy produced by oil or coal, many have herald it as a cleaner source of fossil energy, whose widespread introduction might help mitigate global warming. A new study found that
Researchers at University of Texas at Arlington conducted tests on more than 100 water wells in Texas and found 30% of these contained ‘alarming’ amounts of arsenic, enough to be considered carcinogenic and seriously threatening human health. These contaminated wells were found in the vicinity of known fracking sites and prior to drilling these were found to be free of arsenic
There’s been a lot of praise and finger pointing alike around the hydrogen economy, and whether or not fuel cells can be scaled to reasonable levels i.e. becoming actually useful. There are a lot of problems with fuel cells in terms of their economy. Fuel cells are some of the most efficient energy converters current technology has fostered so far,
Researchers at Purdue University found that a local bus system running on natural gas is more economically feasible and less harmful to the environment than the currently employed diesel model. The team lead by Purdue University energy economist Wally Tyner also concluded that natural gas is a better fit than electric-hybrid. The analysis was was specific to the Greater Lafayette Public
A new study of 100 private water wells in and near the Barnett Shale showed elevated links of contaminants such as arsenic and selenium to fracking sites used for shale gas; the study, which was conducted by UT Arlington associate professor of chemistry and biochemistry Kevin Schug was published in Environmental Science & Technology. The research focused on water samples,
There has been a lot of fuss lately about shale gas, which has become increasingly important in the past decade, particularly due to hydraulic fracturing (or fracking), a modern technique used to extract it from the underground. Many have proposed natural shale gas as a supposedly clean bridge fuel, fit to address climate change and also industrial energetic requirements; as
