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.

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.

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 destruction of the turbines and auxiliary equipment at Russia’s Sayano-Shushenskaya Hydro Power Plant in August 2009 claimed the lives of 75 workers and wrecked an indispensable source of electricity that will take years to fully restore. The disaster, as this report explains, was predictable and preventable.

As wind and solar energy capacity in the U.S. continues to grow, compressed air energy storage (CAES) and other bulk energy storage technologies will increasingly be used to help balance electrical supply and demand.

Composite materials are ideal for producing wind turbine blades because of their strength, light weight, and ability to be tailored to provide the precise mechanical properties needed for any blade design. Now, best practices originally developed for rotorcraft blade manufacturing can be applied to designing and manufacturing wind turbine blades that are constructed from composites.

Recent mandates require government facilities to develop energy policies that enable energy conservation, increase the use of renewable energy, and improve energy security. Utilities with government facilities in their service territory may have opportunities to develop solar and other renewable energy projects that help them meet state renewable portfolio standards while increasing a government facility’s usage of renewable energy. The key to such a win-win proposition is careful structuring of the project agreement to leverage each party’s assets.

In 2010 investment in wind power continued to accelerate, particularly in California and Texas. California also entered several solar projects in the race for financing. The finish line that renewable power developers and their partners are racing to meet is a December 31 deadline to qualify for federal cash grants.

Electro Static Technology’s AEGIS WTG wind turbine grounding ring seeks to prevent bearing damage that could otherwise cause generator failure by safely channeling harmful shaft currents away from bearings to the ground. Maintenance-free, effective at any wind turbine speed, and available for any-size generator, the ring is designed for OEM installation or easy up-tower retrofit. […]
