As the Obama administration takes office, energy resource allocation is both the most critical national security issue and the most critical economic issue facing us. It will be difficult to sustain and improve economic growth unless we implement policies that result in the more rational use of energy resources, especially those for which there is a finite supply.

Just after midnight on Dec. 22, 2008, a 40-acre pond holding coal combustion waste for a Tennessee Valley Authority (TVA) steam power plant ruptured, sending a wave of wet ash across 300 acres of rural land in Harriman County, Tenn. It was the largest coal slurry spill in U.S. history — more than three times the size of the Martin Country, Ky., sludge spill of 2000, and about eight times that of the 1972 Buffalo Creek flood in West Virginia. Unlike that flood, which killed 125 people and injured scores others, this one, Tennessee authorities reported, resulted in no serious injuries or hospitalizations.

A year after Exelon Nuclear ceremoniously announced the selection of General Electric-Hitachi’s Economic & Simplified Boiling Water Reactor (ESBWR) design (Figure 2) as its preferred technology for a proposed two-unit nuclear facility in Victoria County, Texas, the operator of the largest nuclear power fleet in the U.S. — and the third-largest in the world — said it had reconsidered its decision. The company said it is now negotiating separately with Toshiba and GE-Hitachi, both vendors of the Advanced Boiling Water Reactor (ABWR), and with Mitsubishi Heavy Industries for its U.S. Advanced Pressurized Water Reactor (US APWR).

I just renewed my professional society membership dues for the umpteenth year, and while writing the check, I paused to consider if I was getting good value from them. I expect to receive another "suitable for framing" certificate this year, as the number of my membership years ends with a zero, but I wondered if there were other, more tangible benefits.

China has put its nuclear power plans on a fast track, kicking off a construction frenzy worth billions of dollars. In the latter months of 2008, the nation inaugurated construction of seven reactors, and in 2009, work will begin on another 10.

Despite hostilities that linger as a result of the 1986 nuclear nightmare at Chernobyl, Ukraine, and pressure from the European Union to shut down older-generation plants, Eastern European countries from the Baltic to Bulgaria are renovating existing nuclear plants or building new ones. If these projects become reality, the region will be able to secure its power supplies as well as cover the ongoing shortages in countries such as Greece, Macedonia, and Albania.

A confluence of circumstances promised to make 2008 a transformative year for renewable energy in the U.S. States enacted additional, and more demanding, renewable portfolio standards, promoting accelerated and sustained development of "green" energy resources. Increasing concerns about global warming and climate change prompted some of this activity. However, the unprecedented escalation of oil prices to almost $150 a barrel (translating into prices at the pump in excess of $4) was the largest impetus for demands that this nation end its addiction to fossil fuels.

Declining oil prices, supply issues, and dwindling financing may have battered solar energy in recent months, but the industry seems to have sparred well in the research arena. An assortment of institutions separately announced breakthroughs in their quests to boost the efficiency of solar cells. The technological advancements ranged in approach, from the development of an antireflective coating to the formulation of more efficient solar cell materials, but all point to promising possibilities for the industry.

An energy-generating revolving door installed at Driebergen-Zeist railway station in the Netherlands is the latest experiment in eco-building. Dutch company Royal Boon Edam Group Holdings designed the manual door to match the newly refurbished station’s sustainable technology theme, while keeping in mind that the station — converted into a multifunctional area featuring restaurants and a tourist information and visitor center — holds 8,500 commuters at capacity.

Following a press briefing this morning, President Barack Obama signed new executive orders intended to spur “swift action” on both U.S. economic recovery and American energy independence.

Thirty-five percent of the world’s energy comes from oil, and 96% of that oil is used for transportation. The current number of vehicles globally is estimated to be 700 million; that number is expected to double overall by 2030, and to triple in developing countries. Now consider that the U.S. has 27% of the world’s supply of coal yet only 2% of the oil. Coal-to-liquids technologies could bridge the gap between U.S. fuel supply and demand.

This spring, Xcel Energy, along with state and technology partners, is set to test what the utility says is the first battery capable of storing wind energy. The ability to store energy from renewable generation sources with variable output is key to maximizing the value of renewable power in general and to Xcel’s “smart grid” plans in particular.

The future of high-level nuclear waste disposal at Yucca Mountain remains uncertain as a new U.S. administration considers its nuclear agenda. The European Union’s policies remain just as unsettled. With new projects under construction in several countries and a nuclear ban in effect in others, no unified long-term storage approach is in sight.

On October 21, a mass of basketball-sized jellyfish managed to accomplish what activists of every stripe had failed to do: Abruptly shut down Pacific Gas & Electric Corp.’s (PG&E) 1,118-MW Diablo Canyon Unit 2 reactor in San Luis Obispo County, Calif. (Figure 8).

If the rotating equipment and boiler are a plant’s brawn, then a control system that efficiently integrates myriad plant functions is its brains. Luckily, in a power plant, we can perform a brain transplant when the control system becomes unreliable or too costly to maintain. But first, you have to justify that surgery.

Concern about the shortage of skilled workers for the energy industry has grown considerably over the past few years. Most discussions have focused on the shortage of engineers, but recently concerns about the scarcity of technical crafts have arisen as well.

Chances are you have endured the tedious process of removing fuel piping when maintaining just about any gas turbine, especially aero-derivative engines that are usually swapped out rather than repaired in place. One of the most time-consuming jobs after reassembling the fuel piping is checking for leaks at all the flanges. In a large frame-size turbine, that means sealing up to 64 flanges and then removing the seals after the leak testing.

Meeting growing energy demand while reducing greenhouse gas (GHG) emissions is one of the most critical challenges facing our world today.
