Capture and sequestration will help ensure the future of coal-fired power plants. Demonstration projects are allowing utilities to kick the tires on the latest technologies, and to learn how CCS will affect operations and economics at state-of-the-art plants.

American voters dashed the nuclear industry’s hopes for a renaissance last November—or so it seemed. Recent developments in Washington have rekindled those hopes, but will climate-policy brinksmanship lead to a sustainable future for nuclear power?

The operations and planning rules for integrating variable resources aren’t the same across the electric power industry in the United States at present. Opinions are somewhat divided about what these should be, as well as the assessments of potential benefits and costs. In order to support sustainable deployment of variable resources at value, it’s critical to identify major sources of potential problems and to proactively design and implement a systematic framework for managing their unique characteristics as reliably and efficiently as possible.

When Sen. Lamar Alexander (R-Tenn.) announced legislation in November 2009 aimed at doubling America’s nuclear power capacity within 20 years, he compared the clean-energy challenge to fighting a war. “If we were going to war, we wouldn’t mothball our nuclear navy and start subsidizing sailboats,” he told attendees at the American Nuclear Society’s winter meeting. “If addressing climate change and creating low-cost, reliable energy are national imperatives, we shouldn’t stop building nuclear plants and start subsidizing windmills.”

Dramatic changes are coming to the electric industry, sparked by a surge of renewable energy and related transmission. Growth in demand-side resources, conservation and smart technologies will add integration dilemmas to an already complex power system.

To fulfill the promise of the smart grid, utilities need to give consumers a greater range of options as well as the education to make sustainable, energy-saving decisions. That includes integrating demand management into the utility back-office.

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.

With public opposition rising against almost any kind of utility project or investment, collaboration among stakeholders with widely divergent points of view never has been more critical. Three recent utility cases demonstrate how a formal stakeholder collaboration process can build support for otherwise contentious decisions.

The market for demand-side products and services appears poised to explode. What began as separate energy efficiency, demand response and distributed energy program offerings are now coming together in integrated demand offerings. A recent poll of 400 industry professionals suggests such packaged offerings might open new opportunities for service providers while also enhancing the customer experience.
