Top Plants: Covanta Onondaga Waste-to-Energy Plant, Jamesville, New York
Covanta Energy Corp. doesn’t believe in wasting waste. Since 1995 the Covanta Onondaga waste-to-energy (WTE) plant has converted approximately 4 million tons of solid waste into 3 million MWh of clean electricity. Additionally, unlike power plants that use wind or solar energy, this 39-MW WTE facility operates 24/7, making it and similar WTE plants among the most continuously reliable sources of renewable electricity generation currently in operation.
Top Plants: Far West Rice Mill with solar electric system, Nelson, California
Many companies are finding that with solar energy, the sky’s the limit. As costs fall and mandates for renewable energy rise, solar energy is becoming an increasingly competitive source of power generation. Far West Rice Mill is a forward-thinking business that is taking advantage of this economic opportunity by powering its operations with a 1-MW photovoltaic system.
Top Plants: La Collada Wind Farm, Tarragona Province, Spain
Ironically, the Spanish province of Tarragona — well known for its many Roman and Medieval ruins, archeological digs, and multiple World Heritage Sites — now has one of the most cutting-edge wind farms in the world. This wind farm recently added an innovative 3-MW wind turbine, which stands 140 meters (459 feet) high and is the largest nationally manufactured wind turbine installed in Spain to date.
Top Plants: San Cristobal Wind Project, Galapagos Islands, Ecuador
The Galapagos Islands, home of the unusual flora and fauna that inspired naturalist Charles Darwin’s groundbreaking work on evolution, are striving to promote clean energy that protects the area’s unique biodiversity. Part of that effort is the 2.4-MW San Cristobal Wind Project, which displaces diesel-powered electricity generation. This new energy source will cut greenhouse gas emissions and reduce the risk of devastating diesel-fuel tanker spills in a highly protected environment.
Top Plants: Thermo Plant, Beaver County, Utah
Geothermal energy projects are gaining steam in many parts of the western U.S., in large part because geothermal power has the advantage of being a renewable energy source that provides baseload power with no emissions and no waste by-products. One example of the latest developments in geothermal power generation is the recently completed 10-MW geothermal plant in rural Utah, which uses innovative modular power generation units.
Prevailing winds: Trends in U.S. wind energy
Wind power is becoming a mainstream energy source that U.S. utilities are tapping into nationwide as a means of adding clean, domestically sourced energy to balance their generating portfolios. To identify where wind will take us,POWER’s senior editor talked to experts from diverse industry stakeholders about current and future developments.
The return of the Clipper Liberty wind turbine
The Steel Winds project in Lackawanna, New York, was selected as a POWER
2007 Top Plant because of its unusual location (a former steel mill and Superfund site) and because it was the first commercial deployment of the Clipper Windpower 2.5-MW turbine. That report was written just as the project entered commercial service but before a major gearbox problem was identified. For many new designs, it isn’t a question of if problems will occur but of how the manufacturer responds when problems inevitably do occur. For its handling of Liberty’s problem, Clipper Windpower gets an "A."
Transforming transmission is key to power industry’s future
Call it the "trillion dollar conundrum." Really big money is needed to equip the U.S. transmission system to handle a variety of new requirements and increased load, but it isn’t clear how to raise it, spend it, or recover it. Expect new renewables projects to die on the vine until the gridlock loosens.
Commentary: Renewable energy lessons from Europe
Europe has seen tremendous activity in the development of renewable energy as a response to climate change. As a result, some of the most important renewable energy firms operating in the U.S. are based in Denmark, Germany, and Spain. Stable, high-level policy is one reason Europe dominates this sector.

Energy’s Articles of Confederation
An attendee at a recent industry conference made the cynical observation that the dysfunctionality of our national and state energy policies can be attributed to the fact that implementation of any program is subject to institutional limitations akin to those imposed by the "Articles of Confederation." Readers may recall that the Articles preceded the Constitution as the governing compact for the 13 original states.

Speaking of Power
Change is coming
An historic election is over and the people have spoken. President-elect Obama and an expanded congressional majority will now rebalance the economic and environmental importance of coal-fired generation in this country differently than ever before, and that change is unsettling to many. When the expected costs of the anticipated new policies are counted, I predict many voters will experience a severe case of buyer’s remorse.
