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.
The American Wind Energy Association is hosting its annual Offshore Wind Expo in Atlantic City, New Jersey this year. This is the second time the expo has made its way to the Garden State. If you live in the south, here are five reasons to make the trip north of the Mason Dixon line. Early [...]
Officials are confirming that two wind farm proposals in Alabama will not be moving forward. As such, Cherokee and Etowah counties will forego about $27-$43 million in combined new tax revenues – revenue that could have been used to build a new park near Weiss Lake or improve the quality of the lake, provide education scholarships for high school graduates, create a new tourism niche, or reduce local taxes.
Lawrence Berkeley National Laboratory (LBNL) has released its 2013 Wind Technologies Market Report. This annual report notes important achievements for the wind industry. Overall, wind turbine innovation increasingly makes wind energy development across the country a winning proposition. Wind turbine costs and the price for wind energy continues to drop.
Iselle (2014) now joins likes of Irene (2011) and Sandy (2012), as a case study showing that wind turbines can withstand tropical storms and hurricanes. It’s been a while since the United States has been hit by a Category 3 hurricane, or higher. Let’s hope that trend continues.
If Hurricanes Iselle and Julio make landfall, several wind farms will assuredly be in the storms’ paths. But, as we’ve documented with Hurricane Sandy (2012) and Hurricane Irene (2011), hurricanes rarely pose major threats to modern wind turbines. With both of those storms, no damage was reported for any wind farm on the east coast.
The public policy position of Exelon is to oppose subsidies for wind and solar while the company itself purports to be this super-green company and also wants more subsidies for nuclear. That’s just hypocritical.
