Replacing nuclear with wind power: Could it be done?
Many people would like it to be theoretically possible to replace nuclear power with wind power, since the wind is a free resource. The way that I would like to approach the topic is to not discuss the source of power, but to discuss this question from the perspective of “intermittency.” Stating the question another way: Can an...[read more]
Commercial Compressed-Air Energy Storage Plant In Development?
Wind power RFP processes* are common enough these days, typically driven by renewable energy mandates placed on utilities. A recent wind power RFP announcement out of Santa Fe, New Mexico, is different. A new company, Chamisa Energy, has initiated an RFP seeking wind power to pair up with a planned compressed-air energy storage (CAES)...[read more]
Impacts of Variable, Intermittent Power on Grids
The increased generation of variable, intermittent wind power will present a challenge to the management of the power on the New England Electric Grid, NEEG. Because wind power is variable and intermittent, spinning reserves (nuclear plants, regulation velocity less than 1%/min, thermal plants, 1%/min; combined cycle gas turbines, 2.5%/...[read more]
A Story of Power in Venezuela
Originally posted May 2009, given today’s news about Venezuela’s electricity woes, it seems appropriate to repost. I predict sales of diesel generators to do up exponentially across Venezuela on the heels of this news. This is not just a parable, but a true story, not something made up by me to provoke discussion. I personally know the...[read more]

“Hi Rick,Sure, I would gladly try to answer your questions. This might go a bit off topic, but I hope the moderators grant me a little leeway.Yes, I know the difference between empty calorie foods and nutrient-dense foods. Although, to my understanding, protein deficiency is not the primary nutritional issue (micro-nutrients appear to be more important), all 8 essential amino acids can be gained ...”
“For those who think heat pumps are great, they are fantasyTake the Uk for example27 million homes at $10k?? For each heat pump system270 billion dollar. Not cheap! That would buy you a lot of wind turbines or nukesBut besides if 27 million homes add 3kw each to winter peak demand due to their gas boilers having been replaced by electric heay pumps thats near plus 90GW demand. It ...”
