The largest wind turbine blade manufactured in Spain to date, 73.5m (241ft), was transported from the factory to the port in Castellón, Spain on October 20th. LM Wind Power, the manufacturer, filmed the 3.5 hour, 45km (28m) trip show off their product – and made an entertaining mini-film to boot.

German company Max Bögl Wind AG has built the world’s tallest wind turbine. The turbine ‘hub’ is 178m (584ft) tall, and the tower’s total height – to the tips of the upward extended blades – is 246.5m (809ft).
For every meter increase in turbine height, annual energy output is increased 0.5-1% due to lower turbulence and higher wind speeds.

In Delaware County, Iowa, a local landowner found 15 rabbits, with their neck’s broken, spread at the base of a wind turbine. A local land manager said it is likely they were placed to lure and potentially kill eagles with the wind turbines.
Wind power provided Iowa with more than 36% of its electricity in 2016. More than any other state in the USA, and second only to coal for total electricity within Iowa.

On Saturday, a record 24.6% of total electricity came from wind power sources in the 28 countries of the European Union. The majority of this wind electricity was generated onshore (88.7%) vs offshore (11.3%).
With Europe moving into the high wind production winter period, we expect a new season of records being broken. And with massive scale construction continuing for offshore wind farms, these records of 2017 will soon look quaint.

Amazon’s Jeff Bezos inaugurates an impressive new wind farm
Jeff Bezos atop a wind farm breaking it in with a bottle of bubbly is pretty intense. Amazon’s founder made his way up one of more than 100 new wind turbines in Texas celebrating a major renewable energy project coming online.
The 253-megawatt “Amazon Wind Farm Texas” in Scurry County is part Amazon’s long-term goal to reach 100% renewable energy. As of the end of 2016, the company was beyond 40% – and expects to break 50% before the end of 2017.
Last month, it was revealed that Tesla is working with world’s largest wind-turbine maker, Vestas, to deploy batteries at their wind farms.
Now Tesla won its first contract with the company and as it turns out, it’s not only for a wind farm but actually the first solar+wind+energy storage project in the world. expand full story

The world’s first floating wind farm is now feeding into Scotland’s electricity grid. The $260M pilot project, majority owned by Statoil, is the first commercial development in the floating wind field. All prior floating wind turbines were research focused.
Floating wind is being developed because 80% of the Europe’s wind resources are located in water too deep for traditional fixed bottom wind turbines to reach. Additionally, just west of Europe, in the North Atlantic, there is enough wind to power the entire world.

Warren Buffett owned MidAmerican Energy is upgrading wind turbines in Iowa early in their lifetimes in order to take advantage of the newest innovations in gear boxes and blades. Since only small parts of the already developed wind farms need be upgraded – these moves will increase the profitability of the farms. Wind turbines are evolving at a fast enough pace that waiting for standard end of life (30 years) means leaving money on the table.
I estimate an additional $51M/year in revenue from MidAmerican’s repowering.

What goes up, must come down…but what was going down – is now going up.
The US Energy Information Administration (EIA) has projected that the USA’s CO2 emissions from energy usage – burning oil, coal and gas – will increase in 2018. The main driver is a predicted increase in ‘heating degree days’ – number of days that Americans will need to warm their homes. Concurrently, an increase in ‘cold heating days’ – air conditioner needing days, the continued increase of oil burning in cars, and a decrease in hydroelectric generation will also affect the final balance of clean vs dirty energy production.

The whole planet can run on wind power if we really needed to.
A new study postulates that 3 million km2 of open ocean area in the windy North Atlantic could produce enough energy to satisfy the needs of the entire human species during the winter months, while it could cover the electricity needs of North America and Europe during the summer.
