Two hundred miles off the coast of Spain, a small island marked by a massive volcanic crater is about to become a case study for an ultramodern, zero impact society.
Over the last twelve years, engineers, researchers, and residents of El Hierro, the smallest of Spain's Canary Islands, have been building one of the world's most interesting living laboratories for sustainable off-grid living. They erected five towering wind turbines, built a huge reservoir that works as a battery, and installed three desalination plants that will let the tiny outpost harvest its drinking water from the sea. Now, the $75 million project is almost ready to be brought online.
The entire pioneering system is slated to begin its stab at modern closed-loop living at the end of June. While there are a number of solar power-reliant island communities, the press has dubbed El Hierro the first to live entirely off of the wind. Its only serious predecessor is Samso, a Danish island that's also powered almost entirely by wind power, but unlike Hierro, it's still wired up to the mainland's coal-fired grid.

Thanks to new investments in natural gas and utility-scale solar energy, El Paso Electric, a Texas utility with nearly 400,000 customers, announced on Monday that its electricity mix will be free from coal by 2016. Thanks to successive investments in large solar projects, EPE has doubled its utility-scale solar portfolio in less than one year. “Our west Texas and southern New Mexico region has the right kind of sun for optimal solar energy production, making this region the ‘goldilocks’ in terms of climate, humidity and heat characteristics that allow us to expand our renewable portfolio with cost-effective technologies and reliable energy resources,” said Tom Shockley, Chief Executive Officer at El Paso Electric, said in a statement.
The utility signed a 20-year power purchase agreement with the massive Macho Springs solar plant in New Mexico, a 50 megawatt (MW) facility with the capacity to power more than 18,000 homes.
According to the agreement, signed last year, EPE would buy solar power from Macho Springs for 5.79 cents a kilowatt-hour — less than half the 12.8 cents per kilowatt-hour average price for electricity from new coal plants, according to Bloomberg.
In February, EPE signed a 30-year power purchase agreement with Newman Solar to build a 10 MW solar facility in El Paso that is expected to come online by the end of 2014 and power an additional 3,800 homes.
Deciding “it is in the best interest of its 395,000 customers,” EPE plans to sell off its seven percent stake in the Four Corners coal plant, located on Navajo Nation land near Farmington, New Mexico. The plant came in at number 15 on Environment America’s list of the nation’s top 100 dirtiest power plants, emitting 13.8 million tons of carbon dioxide emissions per year.
wow - that is a stunning figure even without taking coal's environmental damage into account in the cost of power. http://thinkprogress.org/climate/2014/06/17/3449604/texas-utility-solar/ Just need the storage....almost seems a solar plus gas turbine for dark hours is a decent strategy until storage improves.According to the agreement, signed last year, EPE would buy solar power from Macho Springs for 5.79 cents a kilowatt-hour — less than half the 12.8 cents per kilowatt-hour average price for electricity from new coal plants[/HILITE], according to Bloomberg.
moteIt turns out wind power isn’t just a source of clean energy — it also helps protect consumers from price volatility. Texas got the benefit of that on Tuesday, when the state’s wind generation kept its electricity spot price down even as heat waves drove it up in other regions of the country.
Spot prices are the cost of any good or service at a particular time and place. And according to Bloomberg, spot prices on the wholesale electricity market jumped drastically on the PJM Interconnection LLC grid yesterday, thanks to a wave of high temperatures. The grid covers 13 states in the mid-Atlantic region, and by 3pm on Tuesday prices on the PJM’s western hub jumped $44.27 per megawatt-hour to land on an average of $84.82. On the eastern hub, prices shot up $26.64 — a 50 percent increase — to land on $79.86 per megawatt-hour.
But down south in Texas, spot power actually fell 48 cents to hit $46.09 per megawatt-hour at the same time. That was despite temperature highs throughout the state that approached or exceeded the sweltering 96°F that Washington, DC saw that day.
Bloomberg reported that the price drop — or more precisely, the lack of a price hike — was accompanied by a level of wind power generation on the Texas grid that topped forecasts. That grid is largely run by the Electric Reliability Council of Texas Inc. (ERCOT), which reported that “wind turbines produced an average of 7,447 megawatts for the hour ending at 2 p.m. local time, surpassing the day-ahead forecast by 77 percent, or 3,237 megawatts.”
Overall, wind power provided 9.9 percent of the electricity used in the ERCOT region in 2013.
Wind power is already competitive with natural gas and cheaper than coal in many areas of the country, and a recent study by the American Wind Energy Association (AWEA) — an industry trade group — showed states with the most wind capacity actually saw electricity prices drop slightly from 2008 to 2013. Those prices rose almost 8 percent in other states. The findings are backed up by a host of other studies.

I'm always suspect of wind power published numbers ( tho the article's numbers were pretty decent).
Installed capacity versus actual performance - reality shows about 22% of capacity is realized.
So Alec ...is that 4% of global generation capacity?? or actual produced power.
A rather larger difference.
Corner Brook, NL – Beothuk Energy Inc. (“Beothuk”), an international company headquartered in St. John’s, Newfoundland and Labrador, announces its intention to develop large-scale offshore wind farms to meet the energy demands of Atlantic Canada and the North Eastern United States.
Beothuk and the Corner Brook Port Corporation are presently in the evaluation and preplanning stages of identifying a suitable port location for development as a manufacturing facility for offshore wind farm gravity based structures.

Canada: A Growing and Stable Wind Energy Market
By Robert Hornung, PresidentCanadian Wind Energy Association (CanWEA)
Eye of the WindWind energy’s growth in Canada continues to defy recessionary forces. Last year, 2012, saw wind energy’s contribution of clean power to Canada’s electricity supply grow by nearly 20 per cent to just over 6,200 megawatts (MW) of installed capacity, maintaining Canada’s position as one of the world’s leading wind energy markets.
Every 1,000 MW of new wind energy drives about $2.5 billion in investment, creates 10,500 person-years of employment, and provides enough clean power every year for over 300,000 Canadian homes.
New wind energy projects were commissioned in 2012 in: British Columbia, Alberta, Ontario, Quebec, Manitoba, Northwest Territories and Nova Scotia.
Close to 40 per cent of Canada’s new wind energy capacity in 2012 was installed in Quebec, while Ontario continues to lead the country with over 2,000 MW of total installed wind energy capacity now in place.
This past year also saw some important firsts for wind in Canada. For example, the Diavik Mine began operating the first wind farm in the Northwest Territories – a 9.2 MW wind project that will help significantly reduce its reliance on diesel fuel.
In Ontario, the M’Chigeeng First Nation commissioned the first wind farm in Canada to be 100 per cent community and First Nation owned.
But Labrador has copious untapped hydro and are not near the population centres which negates any potential...
It depends on what a subsidy is. I don't know of any underground/metro/subway system that is totally privately both built from 0 and operated. Such systems are so costly that they require the government to capitalize them.
Wind is something similar: it's extremely cheap, except cost of capital. 1 Kw costs 2,000 usd, produces 2,000 to 4,000 kwh a year with maybe a cost of 20 or 30 usd for work, indirect expenses and use of land. You have to add 100 usd of depreciation -not real, but in the books- and capital cost, another 100 usd with a rate of 5%. Subsidies usually are on capital costs, either paying part of it or paying on excess of certain interest rate -so reducing uncertainty and risk-.
Let's charge a modicum tax of 50 usd per ton of carbon dioxide released. That makes electricity generated with fuel oil some 30% more expensive, 70% if its generated with natural gas, and who knows if we used coal. Then any subsidy can be cut including those very easy to get fat subsidies from overseas payable with environmental crisis and granted without even saying "please" and "thank you".
Certainly aluminum refineries already do.
That's one reason I'm kind of excited about the aluminum/air batteries. Very high energy density and sourcing can be from off peak power and remote plus straight forward recycle into the aluminum stream.
It has the elements of a strong component of sustainable industrial.

When it comes to electricity supply, we're caught in a vicious triangle. A bold scheme that pays big business to switch off could be part of the solution
IF YOU have ever played rock-paper-scissors, you'll know the frustration of having no sure winning strategy. Whip out a perfect pair of sharp scissors, and the rock might blunt them. Then again, paper smothers rock, and scissors cut paper. There's no win-win.
So pity those pitting their wits against our energy demands. As consumers, we want energy to be affordable. As a society, we want our supplies to be secure and reliable. And as responsible global citizens, we want power to be clean, green and low-carbon, too. But these demands trump each other in different ways. "It's called the energy trilemma,
I like the general gist of this proposal, are you proposing a global system or a system that each nation should enact and enforce independently?
