Action protects public health and cuts harmful emissions from Pennsylvania power plant.
Hydrogen offers great promise as a renewable energy source. It's staggeringly plentiful (the most abundant element in the Universe) and environmentally friendly (used in a fuel cell, it gives off only water). Unfortunately, storing and transporting hydrogen for personal use is a significant engineering challenge.
On Oct. 9, an underwater volcano started to emerge in waters off El Hierro Island in the Canaries, Spain. Researchers of the Spanish Institute of Oceanography (IEO, Ministry of Science and Innovation) only needed 15 days to map its formation in high resolution. The volcanic cone has reached a height of 100 m and the lava tongue flows down its side, even though its activity has slowed down in the past few days.
Plug-in electric vehicles represent a new direction for environmentally friendly transportation. Unfortunately, plug-in electric cars are currently grid-tie power electronics that can require large quantities of energy -- and time -- to charge. As plug-in cars become more and more widely used, large amounts of power will be required to quickly charge these vehicles.
A team of researchers at MIT has found one of the most effective catalysts ever discovered for splitting oxygen atoms from water molecules — a key reaction for advanced energy-storage systems, including electrolyzers, to produce hydrogen fuel and rechargeable batteries. This new catalyst liberates oxygen at more than 10 times the rate of the best previously known catalyst of its type.
The U.S. Environmental Protection Agency (EPA) recently announced a commitment to using an integrated planning process to help local governments dealing with difficult financial conditions identify opportunities to achieve clean water by controlling and managing releases of wastewater and stormwater runoff more efficiently and cost effectively.
Travelers on U.S. airlines have reason to be concerned this holiday travel season. Fewer seats and traditionally high passenger volumes are a reality for holiday travel. Ticket prices and overall costs also will be higher. While overall airline performance quality has improved each year since 2007, the travel experience has become more stressful and uncertain, especially around the end-of-the-year holidays.
Governments around the world must be prepared for mass migrations caused by rising global temperatures or face the possibility of calamitous results, say University of Florida scientists on a research team reporting in the Oct. 28 edition of Science.
Open refrigerated display cases holding eggs, cheese, drinks and more are a favorite of supermarket chains. Despite the easy access they offer customers, the inefficient energy-guzzlers cost retailers a huge amount of money.
As the planet continues to warm, it appears that seaweeds may be in especially hot water. New findings reported online on Oct. 27 in Current Biology, a Cell Press publication, based on herbarium records collected in Australia since the 1940s suggest that up to 25 percent of temperate seaweed species living there could be headed to extinction.
Chicago area residents have wondered for years about the health risks of using the Chicago River for recreation. According to a University of Illinois at Chicago study, canoeing, kayaking, rowing, boating and fishing on the Chicago River pose the same risk of gastrointestinal illness as performing these same activities on other local waters -- a risk that turns out to be higher than that intended for swimmers at Lake Michigan beaches.
New research from the University of Missouri indicates that Atlantic Ocean temperatures during the greenhouse climate of the Late Cretaceous Epoch were influenced by circulation in the deep ocean. These changes in circulation patterns 70 million years ago could help scientists understand the consequences of modern increases in greenhouse gases.
A substance that may have harmful health effects -- occurs in 94 percent of thermal cash register receipts, scientists are reporting.
Imagine your car running on an abundant, environmentally friendly fuel generated from the surrounding atmosphere. Sounds like science fiction, but UT Dallas researchers recently published a paper in the journal Nature Materials detailing a breakthrough in understanding how such a fuel – in this case, hydrogen – can be stored in metals.
A New Hampshire school bus company has agreed to pay a $25,000 penalty to resolve Clean Water Act violations for having failed to fully implement Spill Prevention, Control, and Countermeasure plans (commonly called “SPCC” plans) at two of its facilities located in Auburn and Weare, N.H.
Climate models have a hard time representing clouds accurately because they lack the spatial resolution necessary to accurately simulate the billowy air masses.
Researcher's solution, already instituted in more than 2,000 households and businesses in Mali, Uganda and Tanzania, involves shared micro-grids with prepaid metering.
Plain, sloping roofs can collect up to 50 percent more rainwater than flat roofs with gravel.
City centers could become virtually car-free within the next 20 years under new plans proposed by University of Leeds transport researchers.
Solar energy is sufficient in scale to meet all of mankind’s energy needs —- if it can be harnessed and stored in a cost-effective way.
