The U.S. Department of Energy (DOE) announced that it will provide $36 million for 15 projects aimed at furthering the development of new and cost-effective technologies for the capture of carbon dioxide (CO2) from the existing fleet of coal-fired power plants. \n\n"Currently, the existing U.S. coal fleet accounts for over half of all electricity generated in this country," U.S. Secretary of Energy Samuel W. Bodman said. "The projects announced today will combat climate change and help meet current and future energy needs by curbing CO2 emissions from existing coal-fired plants." \n\n

But the new technologies-which could help consumers cope with these prices-are unlikely to arrive in large numbers in time for the next oil spike. According to the authors of "The Impact of Plug-in Hybrids on U.S. Oil Use and Greenhouse Gas Emissions," a chapter in the new book Plug-in Electric Vehicles: What Role for Washington, published by the Brookings Institution, cars are durable goods that last well over a decade. "The transformation of the light-vehicle fleet to new internal combustion technologies or to hybrid and plug-in hybrid technologies will take decades from the time such vehicles are widely available at competitive prices," according to the authors, Alan Madian, Lisa Walsh and Kim Simpkins, researchers at consulting firm LECG. They believe it could take another decade from now until the new technologies compete on a price basis, and begin the process of replacing current fleets.

A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

Hydrogen fuel-cell cars have received a great deal of attention over the years as a clean alternative to petroleum-based transportation, producing only water for exhaust. Certainly the technology is known. Demonstration vehicles have been produced by several manufacturers and Honda is starting to roll out a fleet of 200 FCX Clarity fuel-cell cars, available for lease to select customers for US $600 per month. These autos are costing Honda hundreds of thousands of dollars each though, according to Honda's president Takeo Fukui (Wall Street Journal, June 16 2008), and it will take another decade before their cost falls below US $100,000. Although fuel-cell cars remain a long way from providing commercially viable transportation for the vast majority of people, cars are not the only application for fuel cells. Fuel cells are reaching commercial viability sooner in other applications such as portable electronics, including laptops, cell phones, MP3 players and games, aiming to supplement the ability of batteries to power these mobile devices for extended periods of time. There are a number of reasons why fuel cells may prove more competitive in portable electronics than in cars, including the favorable cost, lifetime requirement and easier distribution in this market. One of the companies developing fuel-cell technology for portable electronics is Polyfuel, using its proprietary hydrocarbon membrane technology for direct methanol fuel cells. The cost of power for portable electronics, according to Polyfuel president and CEO Jim Balcom, is up to US $10,000 per watt, compared with US $20-50 for autos, making portable electronics a much more attractive market than cars initially.

U.S. wind industry has raced past the 20,000-megawatt (MW) installed capacity milestone, achieving in two years what had previously taken more than two decades, according to new figures. The 10,000-MW mark was reached in 2006. Wind now provides 20,152 MW of electricity generating capacity in the U.S., producing enough electricity to serve 5.3 million American homes or power a fleet of more than 1 million plug-in hybrid vehicle, according to the American Wind Energy Association (AWEA). "Wind energy installations are well ahead of the curve for contributing 20% of the U.S. electric power supply by 2030 as envisioned by the U.S. Department of Energy," said AWEA Executive Director Randall Swisher. "However, the looming expiration of the federal renewable energy production tax credit (PTC) less than four months from now threatens this spectacular progress. The PTC has been a critical factor in wind's very rapid growth as a part of the nation's power portfolio." The PTC is currently set to expire at the end of 2008.
