How to justify green power without apologizing for the price.
Policymakers have shown considerable interest in the concept of a renewable portfolio standard (RPS), and how it might affect the cost of energy.
The RPS would require electricity providers to include a small amount of renewables-based power - typically less than 3 percent or 4 percent - in their resource mix.
States earmark millions to fund solar projects via system benefits charges.
Making solar power a realistic choice for electric consumers is a burgeoning issue for state utility regulators. As part of electric restructuring, regulators are trying to finance the costs of solar installations.
Key to delivering commercial, on-grid solar power to new markets are state efforts, partnered with other government and industry actions. So far, the system benefits charge, or SBC, is the primary short-term incentive to develop solar, wind, biomass and other renewable resources.
ACCORDING TO ONE RECENT SURVEY, MORE THAN HALF THE U.S. population now lives in states with customer choice. Moreover, industry executives expect 20 to 50 percent of these customers to choose a new electricity supplier by year end. %n1%n
With changes expected in the way electricity is generated, delivered and sold, exerting pressure on prices, what does the future hold for energy storage technologies?
After all, restructuring efforts appear most active in the highest-cost states -- those with average electricity prices running above 7 cents per kilowatt-hour.
Arizona would wager on electric competition, hedge its bet with a solar portfolio.Looking for a new way to promote renewable energy?
With little fanfare, most aspects of the U.S. energy system seem to have settled into a fairly stable, predictable pattern. To my mind, we have reached an "energy plateau" likely to persist for maybe a decade or more into the future.
Energy is not now high on the radar screen of the general public, so there is little public pressure for significant change in the U.S. energy system.
PV technology combined with storage offers a cost-effective alternative to capacity additions.By John Byrne,

Until recently, both regulators and electric utilities have considered photovoltaic (PV) technology (i.e., solar cells) an unattractive
energy-supply option because of its relatively high cost. Now, however, a number of utilities have shown interest in using PV for peak-shaving.
