To the Editor:
Your editorial (“Wanted: Bold, not Goofy,” May 2009) is profoundly disturbing, so lacking in balance.
Focusing on What We Do Know
Those of us who ply our trade as power industry journalists, and those of you who read the fruit of our labors, see all too well the uncertainty being created by highly contentious public policy on energy.
Future Opportunities for the Energy Ecosystem
The face of generation is changing. Although no one can predict what will happen 10 or 15 years into the future, today’s technology, carbon and environmental sustainability assumptions help us visualize a very different energy supply ecosystem.
An NSR Template
Understanding the components and precedents of New Source Review is only the start; now you need to develop a methodology to use when evaluating your projects.

The Unsinkable Burlington Plant
Commuting to work by boat and piling up coal to block floodwaters is far from routine for power plant personnel.
The Trouble with Inverters
MIT’s Technology Review reports that a study of solar arrays in actual operation shows poorly designed or faulty inverters—devices that convert the DC power produced by solar panels to AC power—can dramatically lower net power output.
EIA Forecast Sees Electricity Demand Slump Through 2009
During the first quarter of 2009, total U.S. electricity consumption fell by an estimated 3 percent compared to the same period last year, according to data from the Department of Energy’s Energy Information Administration.
