Green Imagineering

Perception trumps reality at Florida ‘solar city.’

Once upon a time, a real estate developer dreamed of building a planned community. The developer, Syd Kitson, envisioned a “city of tomorrow™” in southwestern Florida, designed for efficiency, convenience and harmony with nature. Instead of driving cars everywhere, the 45,000 residents of Kitson’s Babcock Ranch would ride bikes to school, and walk to the cinema. They’d take a tram to visit friends in another hamlet, on the other side of a lush wildlife preserve.

The Efficiency Mandate: Net-Zero Neighborhoods

Utilities explore the potential of zero-energy homes.

Utilities are leaving no stone unturned in their search for ways to save electricity. Federal incentives will support new technologies and projects, but can those incentives overcome structural barriers that stand in the way of major efficiency improvements? editors explore challenges and opportunities arising from the new efficiency mandate.

Paying for the Green Grid

Subsidies might not be the best solution for interconnecting renewables.

Supporters of renewable energy are seeking to socialize the cost of a new interstate highway system for transporting green power. But utilities and transmission owners will build or finance new transmission systems to serve economic demands. Policy makers shouldn’t pre-ordain the direction of industry progress.

Redefining PV Capacity

Effective metrics give solar its due credit.

Photovoltaic (PV) power generation is an intermittent, non-dispatchable resource generally considered as energy-only with no capacity credit. However, there is ample evidence that solar energy reliably is available at peak demand time when loads are driven by day-time commercial air conditioning, and can contribute effectively to increasing the capacity available on a regional grid.

Back to Gas

Utility turbines bridge the capacity gap.

Utilities are turning to natural gas as a bridge fuel, and to support non-dispatchable renewables.

Ontario's Standard Offer

Financial incentives work, but beware potential pitfalls.

The province’s renewable program was vastly oversubscribed. But was it successful?

RPS Race

As green mandates tighten, utilities scramble to comply.

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.

Revisiting the Keystone State

Rate caps have squelched competition in Pennsylvania.

The prolonged period of capped rates in Pennsylvania—years longer than in any other state—has produced some benefits and some drawbacks. On the plus side, due largely to the rate caps, electricity costs in the Commonwealth have fallen from 15 percent above the national average in 1996 to below the national average in 2007. This has been a significant benefit, but a temporary one that many have taken for granted.
