Originally published on RenewEconomy. By Giles Parkinson. The cost of large-scale solar projects has fallen by one-third in the last five years and big solar now competes with wind energy in the solar-rich south-west of the United States, according to new research. The study by the Lawrence Berkeley National Laboratory … [continued]
Continuing on from yesterday’s “Renewable Energy Big Pic” post, here’s Renewable Energy Big Pic: Part 2. As noted yesterday, this two-post series is basically a presentation I gave to a class of renewable energy graduate students this week. Enjoy this second part, and chime in below if anything interesting or … [continued]
“For several 15-minute intravals [last Friday] morning, wholesale electricity cost nothing,” Elizabeth Souder of dallasnews.com reported last Friday. Interesting, eh? If you’re a regular CleanTechnica reader (or if you read the headline…), I think you can guess why. Yes, wind power being cheap as heck, the wind blowing strong at night, and less electricity demand is the mixture that caused this to happen.
As I’ve said many times on here, Wind.Is.Cheap. Additionally, as I covered earlier this year, wind power is making electricity cheaper.
At the American Wind Energy Association’s (AWEA) WINDPOWER 2011 conference in California this week, wind energy giant Vestas unveiled a new and improved design of its most popular wind turbine.
The anti-wind people are at it again, saturating the media with claims that wind energy is “worthless” because wind doesn’t blow all the time. Nothing could be further from the truth.
Following up on my overview post on the cost of wind power, here’s a little discussion on some more intricate matters related to wind power.
What’s the cost of wind power? Well, of course, it depends on where you are and who you ask. But I’m going to do my best here to share some reliable information and put it in a useful context for you.
There are some very widespread and incorrect conceptions about renewable energy sources. I mention and discuss some of the most common ones below.
