New Study Advocates Shift Toward Long-Term Gas Supply Agreements
Current low gas prices offer a unique opportunity to lock in savings for years to come—but only if utilities, gas suppliers, and regulators have the vision to commit to a new way of doing business.

Tomato or To-mah-to? GE Gas Engines Do Triple Duty in California Hothouse
Growing hothouse tomatoes might not be the first application that comes to mind for a natural gas–fueled combustion engine, but that’s exactly what an innovative grower in Southern California is doing, with some help from General Electric (GE).

CoalAre Economics Trumping Regulation?
The fate of coal-fired generation remains fluid as owners weigh environmental rules, the effect of low natural gas prices, and the shifting cost of investing in emissions control technology. An analysis of generating unit data suggests that smaller, older, less-efficient, and less-frequently dispatched assets are most vulnerable to retirements. Recently accelerated retirement dates for some units indicate that economic factors are a more important determining factor than pending environmental mandates

Why EDF Is Working on Natural Gas
Many environmental groups are calling for a ban on hydraulic fracturing and are even lobbying to end natural gas development altogether. The Environmental Defense Fund is not. The EDF energy program chief counsel explains why.

CoalTHE BIG PICTURE: A Big Switch
The widespread transition from coal to natural gas for new generation is exemplified by the morphing fleets of some of the biggest U.S. generators. Figures show the amount of power generated by each company using coal (top) and natural gas (bottom).
