Mechanical engineers at the University of Texas at Austin have identified a material they believe will make cheaper, longer-lasting PEM fuel cells without compromising their energy production. Professor Arumugam Manthiram and colleagues reported recently in thethat they have successfully used a cheaper ...
The impacts of climate change are pushing electrical grids around the world to their limits. Last year, an unprecedented polar vortex caused consumers in Texas to crank up their thermostats and overwhelm the power grid, resulting in days-long power outages. And in California, power is preemptively...
The underground water storage facility in Liwa, Abu Dhabi can store 5 billion gallons of desalinated water, and another such facility is also being constructed in Al Ain. Masdar Institute said that co-generation power and desalination plants that produce most of Abu Dhabi’s electricity and wate...
FRP manufacturers who want to qualify FRP panels for use as exterior wall assemblies on buildings of any height must also meet the acceptance criteria of a battery of fire- and smoke-related performance tests.
Newly produced, electricity-conducting plastics could dramatically lower the cost of manufacturing solar panels. By overcoming technical hurdles t
摘要: Day-ahead power prices in the Electric Reliability Council of Texas fell from January to February, weakened by lighter load, lower gas prices and higher wind output. Despite tight power supply conditions, natural gas weakness contributed to lower summer forwards. 年份: 2019 收藏...

A device about the size of a smartphone controls the home’s electricity use based on energy prices that are assessed and recalculated every five minutes according to the energy demands of the market. TESS only controls devices that are flexible in their electricity use – things ...
Popular wisdom is that wind power is the best choice for electricity generation, especially if the goal is to reduce the emissions of mercury, SO_2, NO_x, or CO_2. However, in a paper published in this issue of ES & T (pp 8578-8583), researchers report that consumers in Texas paid...
Not requiring electricity to prompt the reaction may be convenient in some circumstances and also keep costs down. "A molly catalyst is essentially a 'green' technology," said Chou. "We used sunlight for the experiment's motive power. The light is processed through a dye, which harvests the...
