Last October, Hurricane Sandy knocked out power to nearly all of Public Service Electric & Gas Company’s (PSE&G) 2.1 million customers. The storm showed customers in New Jersey and all over the U.S. that something more needs to be done in terms of grid resiliency. In that regard, PSE&G announced on Tuesday that it…Read More
Geothermal wells are traditionally drilled in locations where hot and permeable rocks make it easier for underground liquid to heat up. Throughout the country there are hot rock formations that have the potential to produce energy but lack either permeable rock or adequate water underground to produce the hot water and steam. This is where Enhanced Geothermal System (EGS) technology enters the scene.
EGS technology, explained in more detail here, is a man-made process that injects fluid underground to create reservoirs, causing pre-existing fractures to re-open thus creating permeability. Fluid circulates throughout the hot permeable rock which createsRead More
With the cost of solar installations continuing to drop, the potential to transform energy production in the United States increases. Tempe, Arizona-based First Solar, one of the world’s leading solar manufacturers, believes that as soon as next year, it could be producing solar at 10 cents per kilowatt-hour without subsidies – a price that would compete with power from fossil fuels in some areas. According to an article in Technology Review, the company believes it can reduce that cost to 7.5 cents per kilowatt-hour by 2016.
This week, First Solar announced that it achieved a new world record mark for efficiency with its thin-film cadmium telluride solar panels. Because the company hasRead More
The consulting firm Deloitte released its annual overview of U.S. energy markets in 2012. Total renewable energy capacity acquired in 2012 (8.4 GW) stayed about the same as in 2011 (8.3 GW) which came as a surprise to many analysts in the renewable energy sector partly because 2012 presented lowered natural gas prices, limited government assistance, and competition.
“Declining technology costs are already making certain renewables more competitive with conventional generation,” the report said.
Wind power experienced the most growth in 2012 largely due to the expiration of theRead More
As a side note: Mayor Daley is noted for creating the Chicago Center for Green Technology (CCGT) that serves to educate the public about green designs. The facility is housed in a rehabilitated municipal building that was first in the U.S. to receive an LEED Platinum rating for its use of green technology.
Electricity consumption in the United States is much more evenly distributed than income or wealth, according to data published last month by Virginia energy efficiency company Opower. The company noted that the top 1 percent of homes consume 4 percent of residential electricity. This is a more even distribution than income, where the top 1…Read More
An Interesting article was just published by Lexington Institute’s Mike Barrett and Robert Gamble about the US power grid, its vulnerability to cyber attacks, and what it means to you. “As outgoing Secretary of Defense Leon Panetta recently noted, “the next Pearl Harbor could be a cyber-attack.” Those in the know agree, observing that cyber-terrorism…Read More
