Wind power, which is one of the most renewable energy sources known to man, is harnessed through wind turbines in wind farms.

The Guardian has an article on plans to expand micro-hydro generation in Britain - Canals and rivers to lead micro-hydropower revolution Britain's canals and rivers have already been heralded as a low-carbon way to tranport Tesco groceries, a test-bed for hydrogen boats and a opportunity to build more wind turbines. Now they're being billed as a chance for micro hydropower to flourish under new plans unveiled today by British Waterways, which maintains 2,200 miles of the country's canals and rivers. In partnership with The Small Hydro Company, British Waterways said it intended to build 25 small-scale hydro-electric schemes with a capacity of 40MW, enough to power 40,000 homes. While far smaller in capacity than offshore wind farms switched on in 2008, the hydro initiative hopes to raise £120m in private capital over the next three years, create 150 construction jobs and reduce CO2 emissions by 110,000 tonnes annually. Underwater turbines will be installed next to existing weirs and will not affect the navigation of canals and rivers. Larger waterways such as the Trent and Severn rivers will be used for the first hydro power projects, with many of the installations likely to be located in the East Midlands and Yorkshire. It is hoped the first of the 25 hydro installations will be generating renewable electricity by 2010.

A MAJOR criticism of wind farms is that they are intermittent. Wind does not blow consistently and, as a result they do not provide a continuous supply of power, but must be backed up by conventional fossil fuel plants. However, a renewables firm believes it has hit on a solution, and is hoping to use it in Scotland. A hydrogen plant would store energy from the wind farm, creating a reserve that could be dipped into on demand, so that even when the wind was not blowing, an electricity supply would be available.

President Obama's proposed $9.9 billion Energy Department budget contains up to $28 million for a Pantex wind farm that would be designed to meet the nuclear weapons plant's energy needs. The Pantex Renewable Energy Project would be built on land in the vicinity of the plant and could generate surplus electrical power that could be sold to utilities, according to budget documents. Preliminary plans call for the wind farm to be built by 2012. The project's overall scope would depend on future funding, but plans call for enough wind turbines to generate up to 75 megawatts of electrical generating capacity. Initial funding would only support construction of a 10- to 15-megawatt system.

Inhabitat is doing a "Energy 101" series to explain why smart grids are necessary - Energy 101: Where Does Our Power Come From ?. Today we're excited to announce the launch of our new Energy 101 series,. in which we'll be exploring the future-forward technologies that stand to upgrade our grids, reduce our energy footprint, and slow the speed of global warming. Unless you have been living in a cave for the past few years, you've probably heard terms like "energy conservation", "off-grid energy", and "smart grid" tossed around. But before getting into the nitty-gritty of transitioning to renewable energy, we should stop and examine where exactly our power comes from now. Unless you derive all your power from on-site renewable energy sources like solar panels or wind turbines, chances are that you're connected to the power grid, a vast network that delivers electricity from suppliers to consumers. Right now, most energy on the grid comes from generating plants. These plants still usually get power from traditional sources like coal, nuclear, and hydroelectric dams. But as concerns over carbon emissions, safety, and long term sustainability of these sources grow, electrical utilities have begun to switch over to renewable energy sources.

LONDON: The government opened a major new phase on Wednesday in its drive for renewable energy, calling for bids to build up to 25 gigawatts of offshore wind turbines, triple the amount in the pipeline. The announcement by the government agency, the Crown Estate, which owns the seabed surrounding the country was welcomed by British Wind Energy Association chairman Adam Bruce as "impressively bold."

Duke Energy announced that it will expand its renewable power business with the development of a second wind energy project in Cheyenne, Wyoming. The company also announced that it has signed a power purchase agreement for the project and has secured turbines.

Kestrel is a company which is committed to deliver renewable energy needs for the coming generation and they put their effort in reducing the use of fossil fuels.

Renewable energy source from wind. Interesting read.

The rolling plains of Castilla-La Mancha are dominated by the windmills that provoked the fevered imagination of Don Quixote. But Spain's relentless investment in wind power and other renewable energy sources has proved wrong those who thought it was tilting at windmills. The sleek white wind turbines and hydroelectric plants that have sprung up across the country in recent years generated 30 per cent of Spain's energy this year for the first time.

Nearly 100 MW of turbines are expected to come from General Electric, leaving the utility and energy developer looking for more suppliers to meet a scheduled late-2010 commercial launch.

The US could replace all its cars and trucks with electric cars powered by wind turbines taking up less than 3 square kilometres - in theory, at least. That's the conclusion of a detailed study ranking 11 types of non-fossil fuels according to their total ecological footprint and their benefit to human health. The study, carried out by Mark Jacobson of the atmosphere and energy programme at Stanford University, found wind power to be by far the most desirable source of energy. Biofuels from corn and plant waste came right at the bottom of the list, along with nuclear power and "clean" coal.

Feed-in Tariffs in 70 words or less: Government and power utility offers premium, long-term contracts to residential, commercial, and industrial citizens to generate power on-site. Rates are based on the cost of buying and installing various renewable energy systems, but only paid on actual power produced. Citizens purchase back grid power, as per usual, from utility at regular prices. Increase in cost is paid for with a small surcharge to all electricity ratepayers.

PETROL should be included in Australia's carbon emissions trading scheme, but low-income households should be compensated for higher power and fuel bills, the nation's top climate change expert has warned. Issuing a stern challenge to the Rudd Government to include petrol in the scheme, when it begins in 2010, Ross Garnaut warned of dire consequences for Australia's natural icons unless urgent and decisive action is taken.
