wind power in china ?

In the wake of new findings released this week putting the Japanese nuclear power plant disaster on par with the world's-worst environmental disaster Chernobyl, China has announced it is downsizing wind production in favor of wind power infrastructure. WIND POWER KIT

China already leads the world in wind power infrastructure but with an outdated power grid, they have been unable to bring the power online. According to PTI, China plans to complete the basic construction of its smart grid by 2015, when it will be able to connect 10 gigawatts (gW) of wind power to the system.

The Chinese government is expected to release new standards for building, monitoring and maintaining wind turbines by the end of the month, to increase the efficiency from 2009 levels.

China has stated its goal of getting 15 percent of its energy from non-fossil fuels by 2020 and wind power is expected to contribute 15 gW.

In order to get to this goal, power experts say China has to shine a spotlight on grid integration and getting wind power assets up to operating speed. According to PTI, a total of 760,000 kilowatts (kW) from wind turbines was wasted last year in Liaoning province alone, because the grid system lags behind wind-power installation.

"Smart generation is what we are looking for," said Patrick Zhao, director of Vestas'' plant power system.

20 % wind energy in the USA by 2030 ?


20% Wind Energy by 2030: Increasing Wind Energy's Contribution to U.S. Electricity Supply
Here you will find the description of the "20% Wind Energy by 2030" report, which was recently published by the U.S. Department of Energy, and related materials and workshops.

Overview
In 2008, the U.S. Department of Energy (DOE) published a report that examines the technical feasibility of using wind energy to generate 20% of the nation's electricity demand by 2030. The report, "20% Wind Energy by 2030: Increasing Wind Energy's Contribution to U.S. Electricity Supply," includes contributions from DOE and its national laboratories, the wind industry, electric utilities, and other groups. The report examines the costs, major impacts, and challenges associated with producing 20% wind energy or 300 GW of wind generating capacity by 2030.

The report's conclusions include:

Reaching 20% wind energy will require enhanced transmission infrastructure, streamlined siting and permitting regimes, improved reliability and operability of wind systems, and increased U.S. wind manufacturing capacity.
Achieving 20% wind energy will require the number of turbine installations to increase from approximately 2000 per year in 2006 to almost 7000 per year in 2017.
Integrating 20% wind energy into the grid can be done reliably for less than 0.5 cents per kWh.
Achieving 20 percent wind energy is not limited by the availability of raw materials.
Addressing transmission challenges such as siting and cost allocation of new transmission lines to access the Nation's best wind resources will be required to achieve 20% wind energy.

Wind Energy Mission, Vision, and Goals
The program's mission is to lead the nation's efforts to improve wind energy technology through public/private partnerships that enhance domestic economic benefit from wind power development and coordinate with stakeholders on activities that address barriers to wind energy use.

Vision
The Presidential Advanced Energy Initiative (AEI) presents a vision for the future development of wind energy by stating that "areas with good wind resources have the potential to supply up to 20% of the electricity consumption of the United States." To support that vision, the Wind Energy Program collaborates with federal, state, industry, and stakeholder organizations to lead wind energy technology research, development, and application efforts that will contribute to significantly increasing the use of wind energy to as much as 20% by 2030.

Goals
The program has defined goals for its technology viability and technology application activities that will position wind power as an attractive advanced technology option for the twenty-first century. These goals are:

By 2010, facilitate the installation of at least 100 megawatts of wind energy in 30 states from a baseline of 8 states in 2002; and by 2018, facilitate the installation of at least 1,000 MW in at least 15 states, from an estimated baseline of 3 states in 2008.
By 2012, reduce the cost of electricity from large wind systems in Class 4 winds to 3.6 cents per kilowatt-hour for land-based systems from a baseline of 5.5 cents per kilowatt-hour in 2002.
By 2012, complete program activities addressing electric power market rules, interconnection impacts, operating strategies, and system planning needed for wind energy to compete without disadvantage to serve the nation's energy needs.
By 2014, reduce the cost of electricity from large wind systems in Class 6 winds to 7 cents/kWh for shallow water (depths up to 30 meters) offshore systems from a baseline of 9.5 cents/kWh in 2005.
By 2015, expand the number of distributed wind turbines (1 kilowatt or larger) deployed in the U.S. market fivefold from a 2007 baseline (2,400 units)

Car is powered By Wind ??


A new carmaker has a plan for cheap, environmentally friendly cars to be built all over the country

An air-powered car? It may be available sooner than you think at a price tag that will hardly be a budget buster. The vehicle may not run like a speed racer on back road highways, but developer Zero Pollution Motors is betting consumers will be willing to fork over $20,000 for a vehicle that can motor around all day on nothing but air and a splash of salad oil, alcohol or possibly a pint of gasoline.



The expertise needed to build a compressed air car, or CAV, is not rocket science, either. Years-old, off-the-shelf technology uses compressed air to drive old-fashioned car engine pistons instead of combusting gas or diesel fuel to create a burst of air to do the same thing. Indian carmaker Tata has no qualms about the technology. It has already bought the rights to make the car for the huge Indian market.

The air car can tool along at a top speed of 35 mph for some 60 miles or so on a tank of compressed air, a sufficient distance for 80% of consumers to commute to work and back and complete daily chores.

On highways, the CAV can cruise at interstate speeds for nearly 800 miles with a small motor that compresses outside air to keep the tank filled. The motor isn't finicky about fuel. It will burn gasoline or diesel as well as biodiesel, ethanol or vegetable oil.

This car leaves the highest-mpg vehicles you can buy right now in the dust. Even if it used only regular gasoline, the air car would average 106 mpg, more than double today's fuel sipping champ, the Toyota Prius. The air tank also can be refilled when it's not in use by being plugged into a wall socket and recharged with electricity as the motor compresses air.

Automakers aren't quite ready yet to gear up huge assembly line operations churning out air cars or set up glitzy dealer showrooms where you can ooh and aah over the color or style. But the vehicles will be built in factories that will make up to 8,000 vehicles a year, likely starting in 2011, and be sold directly to consumers.

There will be plants in nearly every state, based on the number of drivers in the state. California will have as many as 17 air car manufacturing plants, and there'll be around 12 in Florida, eight in New York, four in Georgia, while two in Connecticut will serve that state and Rhode Island.

The technology goes back decades, but is coming together courtesy of two converging forces. First, new laws are likely to be enacted in a few years that will limit carbon dioxide emissions and force automakers to develop ultra-high mileage cars and those that emit minuscule amounts of or no gases linked with global warming. Plug-in electric hybrids will slash these emissions, but they'll be pricey at around $40,000 each and require some changes in infrastructure -- such as widespread recharge stations -- to be practical. Fuel cells that burn hydrogen to produce only water vapor still face daunting technical challenges.

Second, the relatively high cost of gas has expedited the air car's development. Yes, pump prices have plunged since July from record levels, but remain way higher than just a few years ago and continue to take a bite out of disposable income. Refiners will face carbon emission restraints, too, and steeply higher costs will be passed along at the pump.

Tata doesn't plan to produce the cars in the U.S. Instead, it plans to charge $15 million for the rights to the technology, a fully built turnkey auto assembly plant, tools, machinery, training and rights to use trademarks.

The CAV has a big hurdle: proving it can pass federal crash tests. Shiva Vencat, president and CEO of Zero Pollution Motors, says he's not worried. "The requirements can be modeled [on a computer] before anything is built and adjusted to ensure that the cars will pass" the crash tests. Vencat also is a vice president of MDI Inc., a French company that developed the air car.
