Mandatory renewable portfolio standards are becoming the norm. But after low-hanging green fruits are harvested, renewable power might get scarce. Many utilities will struggle to meet RPS requirements until lawmakers create stable federal policies and a national market for green credits.

As market forces transform the IOU business model, Apple’s iPhone provides a metaphor and possible example for the industry to follow. The iUtility will emerge as companies renegotiate the regulatory compact and reinterpret the traditional rate formula.

Photovoltaic technologies are beginning to appear more attractive than concentrated solar thermal plants. PV’s competitiveness is improving from technical and operational advancements, as well as significant commitments made by such utilities as Southern California Edison. In the long run, distributed central PV plants likely will gain a strong market position.

“Biomass Fuel Foibles states that biomass plants will reduce greenhouse gas (GHG) emissions. We own several wood (biomass) plants and yes, sulfur emissions are almost zero, but there is always a NO_x problem. NO_x can be controlled using urea injection and other technologies. But isn’t the main concern over the emission of CO₂, and don’t biomass plants or any process that combusts fuel produce CO₂ that cannot be controlled?

In a hydrogen-electric economy, power companies could see very large market opportunities—and play a major role in enabling and accelerating implementation.

A growing movement to bring plug-in hybrid and all-electric cars to market has emerged, bolstered by the undeniable economic and national-security benefits that result from displacing gasoline with electricity. Also, our editor-at-large talks with Tesla Motors CEO Martin Eberhart.

"If you build it they will come" has not proven to be applicable for green-power programs. Utilities have to build their programs in the right way, with the right rewards and incentives—then the customers will come. If utilities do not do this, then the effort to expand renewable energy markets will suffer a great setback, one from which it will take many years to recover.

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].
