In a few places, wind power is already as cheap as natural gas or coal-fired electricity. By and large, however, it’s still a bit more expensive in most regions ’round the world. But not for long.

Climate Progress points us to this report in Bloomberg New Energy Finance, which has the scoop: “The cost of electricity from onshore wind turbines will drop 12% in the next five years thanks to a mix of lower-cost equipment and gains in output efficiency.”

And that 12% drop will have huge implications, as Bloomberg reports: “The best wind farms in the world already produce power as economically as coal, gas and nuclear generators; the average wind farm will be fully competitive by 2016.”

Siemens Boosts Its Stake in Tidal Power

Marine energy has long looked to be a niche area, capable of meeting just a few percent of global power demand. But this seemingly limited energy source is drawing some big players, the latest being Siemens. The German engineering giant boosted its stake this month in Bristol, U.K.-based tidal energy developer Marine Current Turbines from under 10 percent to 45 percent. The attraction, according to Michael Axmann, chief financial officer for Siemens’s solar and hydro division, is the predictability of marine power.

Solar and wind farm operators struggle to predict tomorrow’s output, and bad forecasts can wreak havoc with power transmission planning and market prices. In contrast, the gravitational pull of the moon and sun that controls tidal cycles provides a sure means of anticipating the output from tidal generating stations. “Power output of the systems could be calculated for centuries in advance,” says Axmann.

Airborne Wind Turbine Could Revolutionize Wind Power

Flying a kite has often been considered child’s play, but a group of inventors think the concept could be used to make wind energy cheaper and more reliable than ever before, potentially revolutionizing wind power forever.

energyNOW! correspondent Josh Zepps met the innovators working to turn the idea of flying a kite into an airborne wind turbine that’s lighter and more powerful than traditional wind turbines. The full video is available below:

Canada Boosting Hydro Power to 88.5 GW to Replace US Coal

Canada’s hydropower industry has plans to invest up to $70 billion on hydro-electric projects across the country in the next 10 to 15 years, increasing its hydro-electric resources – to a truly staggering 88,500 MW.

Most of the additional projects are in provinces with abundant precipitation that is likely to increase in a warming future, making them ideal for hydropower. Hydro-electric power is much cleaner in cold climates than in warm ones, because methane emissions that are caused by rotting vegetation are lower in colder climates. Quebec is building another 4,570 MW, British Columbia: 3,341 MW, Labrador: 3,074 MW and Manitoba: 2,380 MW.

Everything I need to know about hygroelectricity

At double the size of China’s Three Gorges Dam, the 40 GW Grand Inga hydropower project, to be built on the Congo River under an agreement between the Democratic Republic of Congo and South Africa, will be the world’s largest by a wide margin. It will increase Africa’s electricity generating capacity by one-third.

But as IPS News reports, as is unfortunately typical with many big-push style projects in the developing world, the local people will likely get little of the electricity produced by the Grand Inga.

Instead, the power transmission lines are expected to go towards mining and industrial facilities, towards the big cities in South Africa and Egypt, as well as possibly being exported to Europe.

Tidal array off the coast of France will be world’s largest when complete in 2012.

A reader actually shared news about this project with me over 2 months ago, but due to the steady stream of so many interesting cleantech stories, other responsibilities, and the fact that the shared page was in French and I had to learn French first (ok, just used Google Translate), it took me a while to get to it. The project is a “gigantic” (for tidal power) project off the coast of Paimpol-Bréhat in Brittany, France. It is a project of Irish tidal technology specialist OpenHydro and the large French utility company EDF.

The project will eventually include four 2-MW tital turbines from OpenHydro. The turbines are being installed 35 meters (115 feet) deep. They are 22 meters (72 feet) high and weigh 850 tonnes.

South Korea to Build World’s Largest Offshore Wind Farm, Domestic Wind Power Industry

Despite relying on imported sources for 97% of its energy needs, South Korea’s been slow to tap into and develop its wind power resources. That appears to be changing. The South Korean government announced that it will invest 10.2 trillion won (US$9 billion) in building a 2.5 gigawatt (GW) offshore wind farm, the largest in the world.

Located offshore of South Korea’s southwestern coast, the offshore wind farm will be built in three phases by South Korean companies led by Korea Electric Power, the country’s largest electric utility. The first is a 100 megawatt demonstration phase to be completed by 2014. Wind turbines with capacities ranging from 3 MW to 7 MW will be erected mainly off the coast of Jeollabukdo and Jeollanamdo provinces in three stages at a projected cost of 400 billion won (~US$353 million).

Cooperative Wind Farm Ownership Beats NIMBYism

I just read an interesting story on Chinese news site Xinhuanet, of all places, on wind power in Denmark and how a cooperative ownership model has allowed the Danes to leap over the NIMBY hurdle that stops or stalls so many wind power projecs (and energy projects, in general).

“The Danish cooperative model involves private persons in the ownership of wind turbines, because you want the project to be accepted, and also to avoid the NIMBY or, ‘Not In My Back Yard’ effect,” said Hans Christian Soerensen, board member of the Middelgrunden Wind Turbine Cooperative.

Very logical. Want someone to not complain about a major, noticeable change in the area? Bring them into the project!

World’s Largest Wind Power Project Moving Forward

It’s been a long time since we reported on the largest wind farm in the world, the 845-megawatt Caithness Shepherds Flat project in Eastern Oregon (in Gilliam and Morrow Counties, to be exact). I think the last time we reported on it was in April, after Google announced that it was investing $100 million in the project. While there isn’t any groundbreaking news to report, the project is moving forward according to schedule and Phase 1 (which includes 70 wind turbines) is supposed to be fully completed by the end of November.

Construction is on schedule and on budget. Work on the substations, interconnection facilities, transmission lines, and electricity collection systems has been finished. 338 foundations (for all three stages) have been built. All in all, the project is more than 50% complete. By August 2012, all 338 wind turbines are projected to be up and running.
