Wind energy lowers carbon emissions, but adding turbines to the current grid system does not eliminate emissions proportionally, according to a report by researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory.
A Vestas employee, who wishes to remain anonymous, told the Gazette that he needs to shower every day prior to coming home to avoid harm to his children from the resins that get on his skin. The company has been cited by OSHA for violations related to chemicals used at the facility that have caused injury to employees. The Greeley Report said an inside report indicates the plant produces approximately 40 blades per week with each blade generating 1 ton of waste.
According to the investigation by the environmental protection bureau, the fluoride in the water taken from a river near JinkoSolar's plant was 10 times higher than the recommended limit. Residue from the plant that rushed into the river in heavy rains.
Local environmental authorities ordered the PV cell plant to be closed while investigations take place. It has failed a number of environmental waste tests since April when high levels of flouride were found in the river, according to local reports.
While capturing wind energy with Suzlon's giant wind turbine blades didn't pollute, the manufacturer of the equipment did, according to a consent agreement between Suzlon and the MPCA that was filed in Pipestone County District Court. The agreement detailed violations involving air quality, hazardous waste, solid waste and the handling of storm water runoff.
Wind power has the potential to reduce emissions associated with conventional electricity generation. Using detailed, systemic hourly data of wind generation and emissions from plants in ERCOT (Texas), CAISO (California), and MISO (Upper Midwest), we estimate the SO2, NOx and CO2 emissions offset by wind generation in those territories. Our estimation strategy implicitly captures both the marginal unit of generation displaced by wind on the electrical grid, and the marginal emissions reduction from that displaced unit. Our results reveal substantial variation in emissions reduction by territory, which appear to be strongly driven by differences in the existing generation mix. While the environmental benefits from emissions reductions in the Upper Midwest roughly cover government subsidies for wind generation, environmental benefits in Texas and California fall short. Finally, we provide back-of-the-envelope calculations for the average national reductions in emissions per megawatt-hour of wind energy.
Supporters and opponents of commercial-scale wind energy projects on Vermont's ridgelines use a lot of statistics and facts to argue their very different sides of the debate. So it's difficult to sort out how much carbon pollution might be cut if there were big wind turbines in the mountains. As part of a series on the future of wind energy in Vermont, VPR's John Dillon explains the complexities.
The reality is that, as Britain flaunts its environmental credentials by speckling its coastlines and unspoiled moors and mountains with thousands of wind turbines, it is contributing to a vast man-made lake of poison in northern China. This is the deadly and sinister side of the massively profitable rare-earths industry that the ‘green' companies profiting from the demand for wind turbines would prefer you knew nothing about.
Rare earth metals are key to global efforts to switch to cleaner energy -- from batteries in hybrid cars to magnets in wind turbines. Mining and processing the metals causes environmental damage that China, the biggest producer, is no longer willing to bear.
Annette Smith, the head of Vermonters for a Clean Environment (VCE), the only green group opposing wind power in Vermont (the other, Energize Vermont, is really a VCE spinoff) said she had spent a lot of time discussing the wind issue with officials of the other environmental groups, and suspects that one reason they are all so pro-wind is that a few of them have some financial connections with wind power companies.
The construction of industrial-scale wind turbines on forested mountain ridges will result in cumulative negative impacts to our regional water resources. The forested mountain ridges are the areas which receive the greatest amounts of precipitation and therefore serve as the most important areas for groundwater recharge and for maintenance of aquatic habitats in the headwaters of streams that are at the base of the aquatic food chain.
The construction of offshore wind turbines south of Kingsville could threaten the safety of drinking water for 60,000 people, says Union Water System advisory board manager John Kehoe. Kehoe said the construction could cause weeks of turbidity in the water. If the plant can't filter the muddy water and be sure it is getting out pathogens such as E. coli, it could be shut down, Kehoe said.
The report says that the greatly increased use of wind energy in the past few years may have raised pollution levels from coal and natural gas-fueled power plants owned by Xcel Energy Inc. That's because the frequent change in output asked of power plants, in response to the availability of wind and solar power, adds to pollution, the report says.
Individual members of the grassroots group Ridge Protectors Inc., filed an appeal in Vermont's Environmental Court arguing that more ground would be disturbed by the Sheffield wind facility than was approved in the storm water discharge permit issued by the State's Agency of Natural Resources (ANR). The wind developer, First Wind has been approved by the Vermont Public Service Board to erect sixteen 2.5 megawatt wind turbines along a ridgeline in Sheffield, Vermont. The final brief filed by the Ridge Protector appellants can be accessed by clicking on the link at the bottom of this page. An excerpt of the brief is posted below.
At what point does it become a matter of personal responsibility to stand up and speak out to preserve the priceless beauty and health of a God-given resource that once irreversibly damaged by corporate and political greed can never be replaced? ...Now after the introduction of industrial-scale wind turbines and high voltage switchyards and transformers to Sheldon, and the dumping of thousands of tons of industrial waste from the 100 year-old industrial steel site into the agricultural fields where food is grown or cattle graze ... we choose to exercise our rights as a democratic society and therefore stand up and speak out as necessary to preserve this land that is the Orangeville that we love.
Photographs taken at Meridian's West Wind project above the Makara coastline show how sediment has been overflowing from the construction site. The photos were taken by marine environmentalist Jim Mikoz, who wrote an article in the NZ Fishing Coast to Coast magazine with the headline: The dirt behind wind turbines.. your fishing is at serious risk. In response to the article, Meridian wrote a letter to the editor stating that there would be no mud runoff into the sea from its construction site.
This time the focus is Kibby Mountain in western Maine where Transcanada is in the process of developing a wind power project, and where related logging operations by Plum Creek and a sub-contractor have been linked to serious land use violations. Pictures taken at the site by an independent engineering firm and provided to the Land Use Regulation Commission in late October show a logging road so damaged by rain, logging activity and erosion that it created a mudslide described as nearly 900 feet long.
Despite the impending layoff of 184 blade production employees, Gamesa Inc. will install new equipment at its Falls plant as it moves forward with other areas of production. ...The DEP discovered several violations at the plant and Gamesa was forced to pay $639,161 in state penalties. A compliance consent order was issued to ensure the installation of the oxidizer.
The company building the wind plant on Wolfe Island has withdrawn an appeal it had launched to avoid being held responsible for a diesel spill that occurred last fall. Canadian Hydro Developers Inc. had appealed to the Environmental Review Tribunal, an independent provincial agency, after failing to comply with a director's order the Ministry of the Environment issued as a result of the spill. The firm launched the appeal in an effort to have its name removed from the order.
With two pipes beneath a road clogged in Noxen, Supervisor Carl Shook is concerned about runoff from a proposed wind farm in Wyoming County. "There is going to be a lot of water running off the mountain," Shook said. Shook was one of about 30 people last Wednesday who attended a public hearing ...The state Department of Environmental Protection held the hearing to receive public comment as it reviews an application from BP for a National Pollutant Discharge Elimination System permit.
