Renewable energy, though still accounting for a comparatively small portion of overall supply, generates a larger portion of the world’s electricity each year. Combining many of the available solar energy conversion technologies with conventional fossil-fueled technologies could reduce fuel costs while simultaneously helping utilities that are struggling to meet their renewable portfolio goals.

It may seem counterintuitive, but fire can be a serious danger in hydropower plants. In some respects, the danger is even greater than in thermal power stations. Most U.S. hydro plants are 30 to 70 years old but can deliver another 20 or 30 years of service with upgrades — including state-of-the-art fire protection systems. The design options outlined here also apply in large part to other generating stations.

Upgrading a 1970s-era generator control system to new millennium technology in 12 days during a three-week shutdown would require careful planning and teamwork under any circumstances. The quick replacement of the governor and control system at the PT Inco smelter’s hydroelectric generation system is even more impressive because the facility is located in the middle of an Indonesian jungle.

President Obama promoted "green energy" as a signature theme in his presidential campaign. During his first weeks, he reaffirmed his administration’s commitment to renewable resources. In a radio address, he promised to double the nation’s alternative energy capacity within three years and to construct a 3,000-mile transmission grid to "convey this new energy from coast to coast."

What do you do when your research institution is losing roughly half a million dollars annually as a result of multiple electricity outages — and electricity demand keeps rising? If you’re the Illinois Institute of Technology, you turn the challenge into a campuswide learning experience by teaming with the Galvin Electricity Initiative and other experts to design and construct a prototype Perfect Power System (PPS). Even during its implementation, the PPS promises to provide more reliable and sustainable electricity to the university at a lower cost than it had been paying.

A 16% national RPS would require almost a 500% increase in renewable generation in the next decade, or about 32,000 MW. EIA data show that the U.S. had about 8% renewables online at the end of 2007. What’s worse is that very few existing projects would count toward the requirements of this proposed legislation.

The pace at which next-generation nuclear power is developing in the U.S. accelerated this February as the U.S. arm of Toshiba inked an engineering, procurement, and construction (EPC) agreement with an advanced boiling water reactor (ABWR) nuclear development company jointly owned by NRG Energy and Japan’s Toshiba Corp. The agreement seeks to ensure that the two ABWRs planned to expand the South Texas Project (STP) in Bay City, Texas, will be constructed on time, on budget, and to exacting standards.

This article discusses planning, operation, and documentation procedures designed to effectively use the thermal imaging camera as a critical element in an effective reliability program.

House Democrats on Tuesday unveiled a 648-page discussion draft of the “American Clean Energy and Security Act of 2009,” a bill touted as a “comprehensive approach to America’s energy policy” because it seeks to establish, among other things, a carbon emissions reduction goal, a cap-and-trade program, and a federal renewable energy standard.

Two months after Exelon Nuclear dropped GE-Hitachi Nuclear Energy’s Economic & Simplified Boiling Water Reactor (ESBWR) design as its preferred technology for a proposed two-unit nuclear facility in Victoria County, Texas, the company has reached agreement with GE-Hitachi for two advanced boiling water reactors (ABWRs) for that site.
