Renewable

States’ green energy policies are being used to serve multiple agendas. Lawmakers should revisit their renewable incentive programs to better align them with policy goals. A regional approach will yield a more efficient portfolio.

The feds are ready to replace disjointed state policies with a coordinated national renewable energy credit market. Treating low-carbon energy consistently will promote investment in renewables.

The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.

Xcel Energy proposes to create America’s first fully functional intelligent grid, with communications and automation systems linking the network from end to end, power plants to meters. Although Xcel still is deploying the system, it’s shown that the early payoff from smart-grid investments won’t necessarily come from automated metering, but from automation in the distribution network—the “middle mile.” As chief architect of the Smart Grid City project in Boulder, Colo., Ray Gogel served on the front lines in the industry’s technology revolution.

Like other California electric utilities, San Francisco-based Pacific Gas & Electric (PG&E) has been scrambling to meet the state’s renewable portfolio standard (RPS), which requires suppliers to obtain at least 20 percent of their power from renewable energy sources by 2010. Though the RPS includes a variety of technologies, renewables developers are choosing utility-scale solar power more than any other resource, says Hal La Flash, PG&E’s director of emerging clean technologies.

Utilities traditionally have met renewable portfolio standards with power purchases from IPPs. But new approaches are allowing utilities to build their rate bases with investments in solar generation.

Utilities are struggling to predict the costs of greenhouse gas regulation. In the quest for a greener planet, how much should consumers be asked to pay for environmental benefits that might be difficult to measure?

This year has marked a sea change in energy policy, from environmental compliance to transmission pricing. Fortnightly interviews top lawyers to better understand how regulatory developments are affecting the power and gas industries.

The potential for a federal renewable energy standard (RES) and carbon regulation, considered with the effect of state-imposed renewable energy standards, is fueling a strong, but challenging, market for renewable energy. Utilities are competing to sign up the best new projects, the types of renewable technologies available are increasing, and there are various government stimulus programs for energy; yet, the financial markets still are hesitant. Against this backdrop, how should contracts for power from new renewable resources be shaped so that those deals will look as good five, 10 and 15 years after execution as on the day the ink dries?

23 million square miles of tropical oceans daily absorb solar radiation equal in heat content to about 250 billion barrels of oil. Ocean thermal energy conversion technologies convert this solar radiation into electrical power by exploiting the thermal gradient temperature differences between the surface and the depths. This enormous resource merits a closer look as policy makers consider alternative technologies for serving future energy demands.
