  • Mixed Messages

    However bright the future of gas-fired power may appear to be, the industry still needs good leadership to get there. It’s not clear we’re getting it, at least from Washington.

  • Saudi Arabia Makes Huge Push to Expand Gas Turbine Generation Capacity

    A fast-growing population means skyrocketing electricity demand for the desert Kingdom of Saudi Arabia. The government is trying to meet this demand head-on with a massive build-out of gas turbine generation capacity, but long-term success will hinge on its ability to produce reliable domestic supplies of natural gas—a problem for a country whose existence has long been tightly tethered to crude oil production.

  • How About ‘None of the Above?’

    By Kennedy Maize Washington, D.C., 16 April 2012 — So clever of the White House. President Obama says his administration’s latest energy strategy — mimicking his GOP adversaries — is “all of the above.” This is the “welcome ever more trotters into the trough” approach. And most everybody who makes energy loves the free lunch. […]

  • EPRI Report Examines Technical Factors Leading to Cooling Loss at Fukushima

    A report released by the Electric Power Research Institute (EPRI) on Tuesday examining the underlying technical factors leading to the loss of critical systems at the Fukushima Daiichi reactors concludes parameters set for tsunami flood protection were inadequate and that this led to the eventual loss of all practical cooling paths for the reactors.
