Photovoltaic

Chasing after windmills and photovoltaics could well be the stuff of fiction.

Wind and solar cells (photovoltaics or PVs) are two renewable energy technologies that many hope will eventually provide the United States with massive amounts of clean, sustainable electric power for the indefinite future. Indeed, it is often suggested or implied that the United States can look to a future where most, if not all electric power can be provided by wind and photovoltaics [1, 2].

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.

California again is the proving ground. Analysts see DG as the biggest issue since the PUC first mapped its "vision" for retail competition.

Micro maverick Bill Althouse sees a grand conspiracy to blot out customer-owned generation.

Distributed generation is out of the box. It's time for regulators to wake up. The paradigm has already shifted."

That's Bill Althouse talking, president of Althouse Inc. of Albuquerque, N.M., a seat-of-the pants business (he says he's near bankruptcy) that helps homeowners and businesses install on-site generation. I met him via email as I researched why, on Jan.

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.

The Texas PV Coalition has been formed to speed commercial availability of photovoltaic systems as a service alternative to extending utility lines. The coalition, which will be managed by Planergy, Inc., an independent energy service company, includes Rio Grande Electric Cooperative, Inc.; Wise Electric Cooperative, Inc.; Tri-County Electric Cooperative, Inc.; and Lubbock Power & Light. Funding to the tune

of $250,000 was provided by the Utility Photovoltaic Group (backed by the U.S. Department of Energy) and the Texas State Energy Conservation Office.

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.
