This web supplement to "Changing Winds: The Evolving Wind Turbine" examines the debate over the merits of the two most common wind turbine axis orientations.

Imagine this scenario: Two separate power plants experience a bowing problem greater than 18 mils with a steam-turbine rotor. The turbines are from the same manufacturer and several repair options are reviewed. Management at both plants selects an innovative approach involving removal of a substantial amount of material, which is replaced with weld overlay and then machined to correct diameters and centerline of the balance piston area. One plant’s insurance company covers the repair, the other plant’s doesn’t. Why?

The recent tensions in the Middle East and their impact on oil and gasoline prices remind us that the U.S. remains heavily dependent on foreign nations—some of them unstable—to meet many of our energy needs. Of course, oil will continue to have an important place in our energy mix, and expanding our domestic reserves makes sense.

Rules proposed by the Environmental Protection Agency (EPA) under Section 316(b) of the Clean Water Act on Monday call for flexible technology standards, determined on a case-by-case basis, for more than 670 power plants across the nation that pull in at least 2 million gallons per day of cooling water. The EPA said the proposal, which seeks to protect aquatic life, establishes a “common sense framework, putting a premium on public input and flexibility.”

The Senate is expected to vote on Thursday on an amendment introduced by Senate Republican Leader Mitch McConnell (R-Ky.) to small business legislation that could permanently block the Environmental Protection Agency (EPA) from promulgating climate change rules.

Nearly 20 Senate Democrats asked President Obama in a letter today not to agree to spending plans passed by the GOP-controlled House last month that would block funding for the Environmental Protection Agency’s (EPA’s) implementation of greenhouse gas rules.

As chief executives of 34 renewable energy companies urged congressional Republican and Democratic leaders to support the Department of Energy’s loan guarantee program, a study released by the Bipartisan Policy Center (BPC) suggests grants are a simpler and more effective way to help finance projects than tax credits.

With geothermal power being produced in nine states—and with 123 projects across 15 states under development—the U.S. leads the world in geothermal energy production, a new report from the Geothermal Energy Association (GEA) shows.

The Department of the Interior (DOI) and the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) on Thursday said they had begun a process to offer Bluewater Wind Delaware the first commercial wind lease off the coast of Delaware under the “Smart from the Start” Atlantic Offshore Wind program.

California’s Assembly on Tuesday passed a renewable energy mandate that would require the state’s power companies to generate 33%—up from the current 20%—of their power from renewable sources by 2020. The mandate is the most ambitious in the U.S.

The Nuclear Regulatory Commission (NRC) last week completed a Final Supplemental Environmental Impact Statement (FSEIS) for a limited work authorization (LWA) and the combined construction and operating licenses (COLs) for Southern Co.’s Vogtle Units 3 and 4 proposed for construction near Waynesboro, Ga.

Incidents unfolding at the quake-stricken Fukushima Daiichi reactors in Japan has led governments to take extraordinary safety measures around the world. Last week, European Union (EU) ministers agreed to re-check the safety of Europe’s 143 reactors, and in the U.S., regulators are expected to conduct seismic assessments on 27 reactors at 17 plants.

Sept. 30, 2011, is the revised final deadline for reporting 2010 data under the Environmental Protection Agency’s (EPA’s) Greenhouse Gas (GHG) Reporting Program. The agency also last week delayed the release of proposed rules that would govern cooling water intake systems at nuclear and coal plants until March 28.
