Wind energy is growing in use across the U.S., both small and large wind turbines are getting installed at record rates. And the trend is similar across the world. A new report by Transparency Market Research, ”Global Wind Energy & Wind Turbine Market (2011 – 2016),” finds that there’s been a Compound Average Growth Rate (CAGR) of 25% over the last 5 years.

As previously reported, total installed wind power around the world reached 197, 039 MW by the end of 2010. That is expected to reach a tremendous 1,750,000 MW by 2030. The wind turbine market is projected to reach $93.1 billion by 2016.

With 42.3 GW of wind power installed, China has now become the new world leader in wind power, having overtaken the US, with 40.2 GW, which itself bypassed the longtime world leader Germany in 2008.

After four years of doubling its installed wind power capacity annually between 2006 and 2009, China added a record 16.5 GW in 2010. According to a detailed report(pdf) from the Netherlands Environmental Assessment Agency, nearly 20% of all net additional power generation capacity in China is now wind power, nearly on par with its hydro. China now leads the world in large-scale hydropower with 21% of global production.

We all know that wind turbines are one of the most used solutions for clean energy generation but like all things they have bad parts like noise from their blades, inadvertent bat and bird kills. New York design firm Atelier DNA claims it has found the key to solve these issues.

The company has come up with an interesting design  for a wind energy generator called “Windstalk” that ditches the blades in favor of stalks. Resembling thin cat tails, the Windstalks produce clean energy when the wind sets them waving.

5 Countries generating the most wind energy

Email, RSS Follow

Wind energy is one of the renewable and green energy source. It is one of the ways to tackle the energy shortage. About 194,400 MW of energy is produced by the windmills throughout the world. Most of the European countries are utilizing the wind energy than other parts of the world. Wind farms are used to produce the wind energy. Each farm consists hundreds of turbines over hundreds of square miles to produce electricity on large scale. Most of windmills are installed in agricultural region. There are two types of wind farms, one is ‘on shore’ and the another one is ‘off shore’. At present most of the countries are investing in wind farms to tackle the energy scarcity. It is a clean energy and preserves the environment from pollution.

World’s Biggest Tidal Power Plant Opened in South Korea

Email, RSS Follow

A few days ago, the President of South Korea, Lee Myung-bak has officially inaugurated what he claims to be the world’s largest tidal power plant. Mr. Lee claims that the new plant is a symbol of his trademark “low-carbon, green growth” policy of seeking renewable energy resources.

The tidal power plant at the artificial sea-water Lake Shihwa partially started operating in early August 2011 after nearly seven years of construction.

CHIEF Minister Shahbaz Sharif has said that 700 to 1,000 megawatt power can be generated from bagasse in 45 sugar mills of Punjab which is a more economical source of power generation and a strategy in consultation with sugar mills has been finalised in this regard. He was presiding over a high level meeting regarding generation of power from alternative sources here on Monday.

The meeting reviewed in detail the project of generation of power from hydle, coal and bagasse and decided that the project of generation of power from bagasse should be implemented speedily and a transparent policy would be adopted for this purpose. Punjab government and representatives of sugar mills associations would determine the tariff of power generated from bagasse and recommendations would be submitted within a week.

Denver International Airport Expands Solar Generation to Become Largest in U.S.

Email, RSS Follow

With the completion of a 4.4-megawatt ground-mounted solar power system, the Denver International Airport now has more than eight MW of solar power – more than any commercial airport in the U.S. It now receives over 6 percent of its electricity via solar power.

DIA hopes to continue its green initiatives and cost savings with the project. “We support alternative energy applications at DIA because these projects are good for the environment while positively impacting our bottom line; they are financially sustainable,” said Kim Day, aviation manager at DIA, in a press release. “This airport was built with a goal of being green, and with this additional solar array, Denver International Airport now has one of the largest solar installations in North America.”

Sempra to build another solar power plant in Boulder City

Email, RSS Follow

After building the country’s largest photovoltaic power plant in Boulder City, California-based Sempra Generation is coming back to Southern Nevada with even bigger plans.

The company announced plans Thursday to build a 150-megawatt solar energy plant on 1,100 acres in the El Dorado Valley in Boulder City. The new installation, dubbed Copper Mountain Solar 2, will produce nearly triple the amount of electricity generated at the nearby photovoltaic plant Copper Mountain Solar 1, which was opened in 2010.

The addition will generate enough energy to power 45,000 homes, according to Sempra. The cost of the project was not disclosed. Construction is expected to begin in early 2012 and wrap up by 2015, employing about 175 construction workers at any time.

Drax coal power station ‘could be transformed to produce biomass fuel’

The UK’s largest coal-fired power station could be turned into one of its biggest sources of renewable energy – if subsidies are increased.

Drax generated about 6% of the UK’s total renewable power in the first half of this year, through burning straw and other biomass at its Yorkshire power station. This was achieved despite burning a much lower proportion of biomass than the plant could sustain if run under optimal conditions.

Dorothy Thompson, chief executive of Drax, said the power station could be transformed to produce more renewable energy than fossil fuel power, using biomass from straw, waste wood and other sources instead of coal.

Solar toilet turns sewage into power

Email, RSS Follow

Combine sunlight and sewage and what do you get? Sanitation, of course.

Michael Hoffmann at the California Institute of Technology has been experimenting with solar-powered water treatment on a small scale. Now he plans to incorporate this technology into a portable toilet.

Sunlight powers an electrochemical reaction with human waste in water that generates microbe-killing oxidants and releases hydrogen gas. The researchers plan to collect the hydrogen in a fuel cell to power a light or possibly even a self-cleaning mechanism.
