Discusses the recent news that renewable energy (including hydro as well) now supplies more electricity to the US grid than does nuclear power. The post then goes on to list some large solar and wind projects in advanced stages of the development pipeline as a reason for being optimistic that the solar and wind side of the renewables is rapidly growing in scale.
Makes the case for coupling hydrogen production with wind farms in order to deliver more dispatchable power; lessen the need for transmission capacity; as well as other important bottom line benefits.
This post looks at the message promoted by the gas industry that natural gas is the necessary complement to renewables such as solar and wind, because the latter are variable and thus need a backup power source that can quickly be brought on line. There are other and perhaps even better ways of addressing variability that also need looking at.
The clean energy sector is entering a phase of dramatic change in which business models are being transformed against a backdrop of regulatory uncertainty, as the industry emerges from a challenging period caused by the global economic downtown. Technologies and business structures that were once abandoned, are now being revived in several key sectors.
This post answers the recently much hyped focus on wind’s variability problem, quantifying it in clear cost terms that put it in perspective. The post helps clarify the differences between energy, capacity and the ancillary services surrounding ensuring capacity and goes on to answer some of the other related problems that have been alleged for wind energy as its penetration level increases.
The WINDPOWER 2011 Conference & Exhibition, organized by the American Wind Energy Association (AWEA), is coming up this month and will run from May 22nd through the 25th, and will be held this year in Anaheim, California. On Sunday May 22nd, it will kick off with a Careers in Wind Summit, a full, one-day event that precedes WINDPOWER, and consists of two concurrent parts: the WINDPOWER “Careers in Wind” Educational Seminars, and the WINDPOWER “Careers in Wind” Job Fair & Exhibition.
As the nation seemingly and slowly pulls out from deep recession there is indication that cleantech sector employment is helping to lift some areas of the country and is starting to provide some jobs in what has been a painfully jobless “recovery” for far too many. This post, by John Addison focuses on some areas of his home state of California that are helping to drive the California economy and boosting jobs growth.
A new study that is sure to create some controversy proposes that the world can provide for all of its energy needs, including electric, transportation, heating/cooling energy needs using only wind, water, and solar power by 2030.
Will electric cars one day become part of a network of rechargeable batteries that can help smooth out the intermittent nature of wind and solar power? Many experts believe so, pointing to programs in Europe and the U.S. that demonstrate the promise of vehicle-to-grid technology.
