Denmark put into operation its 12th offshore wind farm this October. The €440 million Rødsand 2 wind farm, a 90-turbine installation with a nameplate capacity of 207 MW, was erected for owner E.ON by Siemens Energy—both German firms—over a mere 122 days. The wind farm joins Rødsand I, a 72-turbine installation that began operating nearby in the Baltic Sea in 2003.

At Malaysia’s first waste-to-energy plant, municipal solid waste (MSW) is converted into refuse-derived fuel for use in an integrated steam power plant. This facility was designed to achieve the twin objectives of environmentally friendly MSW disposal and generating renewable power.

Energy is the most regulated sector of the American economy, making public-private partnerships essential to scaling the solar industry. Such partnerships have helped other energy sectors to reach scale over the past hundred years.

A 14-MW pilot plant built by energy firm ELCOGAS at its 335-MW integrated gasification combined-cycle (IGCC) facility at Puertollano in Spain in September captured its first metric ton of carbon dioxide. Now the company plans to begin tests to procure more technical and economic information about carbon capture and storage (CCS), including how efficient it is to co-produce hydrogen and power with carbon capture processes.

Located in the heavily forested country of Finland, the Kaukaan Voima biomass-fueled power plant produces process steam and electricity for UPM’s Kaukas pulp and paper mill as well as electricity and district heating for Lappeenrannan Energia, a city-owned power company. Launched in 2009, the plant can provide 125 MW of electricity, 110 MWth of district heat, and 150 MWth of process steam thanks to one of the world’s largest wood-fired fluidized bed boilers.

Economic and environmental developments markedly affected electricity markets in 2009, driving generation down 4.1% to 3,950 million MWh from 4,119 million MWh in 2008—the lowest level since 2003 and the largest decline in six decades, the U.S. Energy Information Agency (EIA) said in its recently released “Electric Power Annual” report.

Turkey, a country that has seen rapid economic growth since the 1980s, largely spurred by a shift in governmental strategy to open up markets and increase private participation, has been actively overhauling its power infrastructure to meet soaring electricity consumption. According to grid operator Turkish Electricity Transmission Co., national consumption increased to 17 billion kWh this September—an 11% increase over the 15.3 billion kWh consumed in September 2009.

In September, the 300-MW Thanet Offshore Wind Farm, the world’s largest offshore wind energy facility, began operation off the southeastern coast of England. The wind farm has 100 3-MW turbines manufactured by Vestas. The facility will generate electricity equivalent to the annual consumption of more than 200,000 British households.

The Illinois House on Tuesday approved plans to build Tenaska’s $3.5 billion proposed integrated gasification combined cycle (IGCC) plant with carbon capture and storage (CCS) in Taylorville, Ill. The state Senate is expected to vote on the 602-MW plant later today.

Scientists at the Massachusetts Institute of Technology (MIT) have a created a set of self-assembling molecules that can turn sunlight into power, and which can repeatedly be broken down and reassembled by adding or removing solution. The scientific breakthrough—inspired by a natural process used by plants to renew light-capturing molecules that have been degraded by the sun—could mean that researchers are closer to creating a self-healing photovoltaic (PV) technology that can keep repairing itself to avoid loss in performance.
