Demand response — the business of turning down electricity use at homes, offices, factories, and other such sources of demand, to help manage grid needs — has changed a lot over the […]
The Nation’s Nuclear Plants Are Nuked
While the nation has been focused on new sources of natural gas and shale oil, few noticed the slow decline of an older energy source: nuclear power. Today, commercial nuclear power is […]
British Study Finds Savings in Switch to Electric Fleet
Companies could cut the running costs of their fleets* by an average of £350,000 and reduce CO2emissions by more than 5% (830 tonnes) each year by replacing just 10% of their current […]
Study: EVs 35% Cheaper To Maintain Than Comparable Cars
Much ink has been spilled over whether or not electric vehicles are a cost-effective replacement for conventional cars. Considering their high upfront cost, the return-on-investment isn’t exactly a short-term proposition. But a […]
Solar Grid Parity Comes to Spain
Bloomberg reported last week that a number of solar developers in Spain have applied for permits to connect to the country’s electric grid and sell solar power at market prices. Taken together […]
100-Megawatt Power Plant via Variations in Ocean Temperature
A barrier to advancing the development of the massive ocean thermal energy conversion (OTEC) resource is its potentially adverse biological impact, but a new DOE-funded study carried out by Makai Ocean Engineering […]
China’s Wind Market: Growing, But Challenged by Grid Realities
For the Chinese wind industry as a whole, 2012 appears to be another year combining elements of the best of times and the worst of times. China surpassed 50 gigawatts of grid-connected […]
The Year In Solar Power: Prices Crash, Sales Soar, Industry Restructures, Saudis Leap In, CSP Suffers
This year was a big year for solar, both domestically and globally, with some unlikely players throwing their hats into the ring and upping the ante on achievable power generating capacity. Here’s […]
How About 99.9 Percent Renewables?
Combinations of onshore wind, offshore wind, and photovoltaic solar, paired with battery and hydrogen storage in a widespread grid system, could meet 90 percent to 99.9 percent of expected 2030 demand at […]
Uprates can increase U.S. nuclear capacity substantially without building new reactors
Currently (as of July 2012), there are 104 commercial nuclear reactors in the United States. In 2011, these plants provided 786 billion kilowatthours of electricity, or nearly one-fifth of total generation. The […]
