The European Union will continue its 2009 record-breaking pace this year for adding wind power, reports the European Wind Energy Association.
The industry group expects EU countries will install 10 gigawatts of new wind power capacity, the same as 2009’s record, bringing the total to 85 GW by year’s end.
“What is encouraging is that, unlike in 2009, the 2010 results consist of orders placed after the start of the financial crisis,” Christian Kjaer, the group’s CEO, said Monday in a statement. “Wind energy will be competing for the top spot with new gas power plants.”
Europe’s new gas plants produced twice as much power as its new wind turbines four years ago, but the gap narrowed sharply in 2007 and by 2008, wind had overtaken gas, reports The New York Times, citing data from the trade group. In 2009, 7 gigawatts of new gas power was installed, compared with 10 GW for wind.
Peak power in Finland doesn’t occur in the afternoon. It actually happens early in the morning.
That’s because many homes are equipped with electric heating systems, and consumers turn them on to keep warm in the early morning hours, according to Vesa Koivisto, the business development manager at Fortum, a large power producer and electrical distributor in the Nordic region. Power prices can swing from zero Euro cents per kilowatt hour to 1.40 Euros ($1.72) per kilowatt hour. An average home consumes about 9,000 kilowatt hours a year, he added.
“We don’t have the 5 o’clock tea-time peak,” he said during a meeting in Helsinki. “If you don’t have district heating, chances are you are heating with electric.”
The situation, though, may start to change in a few years under an ambitious program to combine time of use pricing with a regional buying pool. By 2013, all homes in Finland will be equipped with smart meters, and consumers will be able to buy power at time-of-use rates set by market on an hourly basis. Finland has had time-of-use pricing programs since the 1950s, but they have largely revolved around estimating power pricing: consumers can sign up for weekend/weekday or night/day pricing programs, but the programs aren’t tied to real-time pricing. (Side note: consumers in the Nordic region get two power bills. The first comes from their power retailer for power consumed. The second comes from the distributor. The retail bill is generally higher, but the two are close, according to Koivisto.)
Residents of Hammarby Sjöstad, a district on the south side of Stockholm, Sweden, don’t let their waste go to waste. Every building in the district boasts an array of pneumatic tubes, like larger versions of the ones that whooshed checks from cars to bank tellers back in the day. One tube carries combustible waste to a plant where it is burned to make heat and electricity. Another zips food waste and other biomatter away to be composted and made into fertilizer. Yet another takes recyclables to a sorting facility.
Meanwhile, wastewater is taken to a treatment plant, from whence it emerges as biosolids for more compost, biogas for heat and transportation fuel, and pure water to cool a power plant, which also runs biofuels grown with the biosolids. Looking at a chart of all this is enough to induce dizziness. “In terms of what you can do at the local level for energy efficiency and renewable energy, it’s incredible. It’s just amazing,” says Joan Fitzgerald, author of Emerald Cities (Oxford University Press, 2010).
Solar panels make electricity when the sun shines, but the suburbs start using the most power when the mases come home from work (ie. night falls). How can utilities shift that solar energy from day to dusk, when it’s most needed?
This week, Sacramento’s utility SMUD turned to startup Silent Power for help. The Baxter, Minn.-based startup was named as a partner, along with GridPoint, SunPower and lithium-ion battery maker Saft, in a project funded with a $5.9 million Department of Energy smart grid stimulus grant. In its first utility pilot project, Silent Power’s “OnDemand” system will hook up about 15 houses in the Sacramento suburb of Rancho Cordova with inverters that connect rooftop solar panels with batteries, controlling the flow of power between them and the grid at large, CEO Todd Headlee told us in an interview.
Spain’s government aims to increase renewable-energy production by about 67 percent during the decade, even as it reduces subsidies for clean power, according to a draft proposal.
Generation capacity will climb to 70 gigawatts by 2020 from 42 gigawatts this year, according to projections in the plan to be presented this month to the European Commission. A gigawatt can power about a million washing machines.
Prime Minister Jose Luis Rodriguez Zapatero is counting on investors to continue building new solar and wind-power installations even as he plans to reduce subsidies for the generators, which currently can earn as much as about 10 times more for their power than utilities that burn fossil fuels.
Converting algae to biofuel remains an intractable problem, even when a company has the resources of a Sapphire Energy or an Algenol.
Imagine the magnitude of the challenge facing Bio Architecture Lab. The secretive company confronts the same battle with high costs as it tunes its bioengineered microbe to convert seaweed to ethanol on a commercial scale. But money is nowhere near as plentiful.
In a rare discussion of its business, the Berkeley company says it is about halfway to its 90 percent fuel conversion target. Confidence is high, says Vineet Rajgarhia, senior vice president of research, who joined the firm in May when it appointed former Shell executive Daniel Trunfio as its CEO.
