TVA recently released its Draft Integrated Resource Plan (IRP). An IRP is a planning exercise to determine utility power plant needs 20 years into the future. The exercise depends on inputs (such as cost and performance data for various power plant types, including wind farms) to develop outputs and recommendations. Some of TVA’s most important inputs for wind power are a bit opaque – especially cost and performance data. But based on the IRP outputs, it appears that the inputs for wind energy are stuck in TVA’s wind energy glory days and are about a decade out of date.
The Plains and Eastern Clean Line project would connect up to 4,000 megawatts of wind power capacity to the southeast. As part of the federal Department of Energy’s Environmental Impact Statement review, the DOE estimates the socioeconomic impacts of the proposed 720-mile high voltage direct current transmission project. Job creation estimates are included in the socioeconomic impacts portions of the EIS. Based on the EIS jobs estimates, lifetime job estimates may conservatively approach tens of thousands of jobs for the Plains and Eastern Clean Line project.
A newly proposed transmission project would connect high quality wind power to the southeast. The proposed Plains and Eastern Clean Line project would provide up to 4,000 megawatts of wind power from western Oklahoma and Texas to the southeast. The project is currently undergoing a federal Department of Energy Environmental Impact Statement (EIS) review process to evaluate potential impacts from the 720-mile high voltage direct current transmission project. Instead of focusing solely on negative impacts, the EIS also weighs a few of the benefits of the proposed project.
Update #2: Pilgrim ended up being down for twelve days! Juno caused problems for the plant but ultimately, it appears that this nuclear plant just generally has problems and isn’t the “poster child” for reliability…read this article in “Cape Cod Today” for more. Update #1: Pilgrim, which creates enough power for up to 550,000 homes, is still down [...]

The post references the recent, exciting news about a solar ballot initiative in Florida recently announced by the coalition Floridians for Solar Choice, of which the Southern [...]
This is a guest blog post by Mary Kate Francis at the American Wind Energy Association. The original post was published here December 17, 2014 on the AWEA blog, Into the Wind. I have big news to report from the front lines of our current campaign to protect wind in 2015. And though there’s bad [...]
Solar photovoltaics, wind energy and solar thermal technology costs have all declined pretty substantially since Lazard’s analysis last year. Natural gas and energy efficiency costs have stayed the same, although to be fair, energy efficiency’s starting low cost of $0 per megawatt of energy saved is hard to beat. Meanwhile, coal, nuclear and integrated gasification combined cycle power costs continue to increase.
This article by Giles Parkinson originally appeared in the Australian publication RenewEconomy on September 16, 2014 and can be viewed in its entirety here. French investment bank Kepler Cheuvreux has produced a fascinating analysis that has dramatic implications for the global oil industry. It estimates that $100 billion invested in either wind energy or solar energy [...]
A recent non-peer reviewed study evaluated the frequency of wind turbine fires around the world. The study found that every year there are approximately 11.7 wind turbine fires that are reported. Based on extremely limited data from an anti-wind farm activist group, the study went on to suggest that wind turbine fires could be ten times higher than what is reported, for a potential total of 117 fires globally every year. As of 2012, there were over 225,000 wind turbines installed globally; thus the chance of a single wind turbine catching on fire is 0.0052% – 0.052%. Stated another way, there’s a 1 in 1,923 to 19,230 chance that a single turbine may catch on fire.
The ALS ice bucket challenge is a drop in the bucket when it comes to wasting water. Coal-fired power plants waste way more water than the ALS ice bucket challenge.
