Last week, Xcel Energy announced a multi-state wind capacity project, anticipated to be the largest in the United States. Spanning seven states, the project covers eleven new wind farms and would generate 3280 MWs at a cost of $3.5-4.4 billion. In its announcement, Xcel emphasized the cost-savings attached to wind power, arguing that it would save Xcel customers in the Midwest $7.9 billion over thirty years. This, rather than the environmental benefits of renewable energy, drove the company’s mission statement: wind was cheap, not just clean.
Moody’s Investor Services now estimates that the falling costs of wind power directly threatens 56 GW of coal power, out of 87 GW surveyed. Moody’s report estimates the MW-hour cost of wind in the Great Plains region at around $20, while coal comes in at $30.

those bats are only likely to be in-flight around dawn and dusk at wind speeds between 2 and 5 meters per second—so Ecotricity and RSPB implemented a mitigation plan by which the turbine is shut off for half an hour before and after dusk, whenever wind speeds are below 7 meters per second.
The new V164 9 MW turbine from Danish company MHI Vestas Offshore Wind produced an amazing 216,000 kWh on December 1, 2016. The turbine was installed at a testing site near Østerild, Denmark. The 9 MW V164 turbine is a tweaked and upgraded version of the 8 MW V164 that was developed in 2012. The V164 has been the most powerful wind turbine to date, holding the previous wind energy generation record before its upgrade. It stands 722 feet high and has blades that are 263 feet long. The V164 has a 25-year life span and 80 percent of the turbine can be recycled when its job is done.

Wind briefly powered more than 50 percent of electric demand on Sunday, the 14-state Southwest Power Pool (SPP) said, for the first time on any North American power grid. Wind power in the SPP region has grown significantly to over 16,000 MW currently from less than 400 megawatts in the early 2000s and is expected to continue growing. One megawatt can power about 1,000 homes.
Wind power briefly reached 52.1 percent at 4:30 a.m. local time on Sunday, SPP said on Monday, beating the previous penetration milestone of 49.2 percent. Wind penetration is a measure of the amount of total load served by wind at a given time.

According to WindEurope, Denmark generated a total of 70 gigawatt-hours (GWh) from onshore wind and another 27 GWh from offshore wind — enough to power the equivalent of 10 million average EU households. This is not the first time wind power has dominated generation statistics in Denmark, with several big wind energy days back throughout 2015. By the end of 2015, the country had a total of just over 5 gigawatts (GW) worth of wind energy installed — made up of 3799 megawatts (MW) of onshore wind and 1271 MW of offshore wind — a number which likely would have increased during 2016.

Electric trains have always been a relatively sustainable mode of transport, with much lower emissions than cars, but as of the 1st of January, 2017, all electric train rides in the Netherlands have become even greener. They are now entirely powered by clean, renewable, wind energy.
Dutch railway companies, of which NS is by far the largest, teamed up with energy company Eneco in 2015 to cut train ride emissions drastically. Originally, 2018 was set as the target for changing to 100% renewable power sources. After having reached 75% in 2016, though, the 100% transition was completed one year ahead of schedule.
The NS alone transports 600,000 people per day, for which it needs 1.2 billion kWh of electricity a year.

Wind farms have made a significant impact in limiting carbon emissions from other sources of power generation in Great Britain. Power from wind farms prevented the creation of almost 36 million tonnes of greenhouse gas emissions from sources such as coal and gas, in a six-year period. This is the equivalent of taking 2.3 million cars off the road, University analysis of nationwide output shows. The study, published in Energy Policy, was supported by the Engineering and Physical Sciences Research Council.
