News Update: Railroad companies are investing more in infrastructure, in large part to carry Asian imports from U.S. ports to major cities. Since 2000, some $10 million has gone into expanding and improving tracks, and buying locomotives, with another $12 million planned. With the high price of gasoline and concerns about carbon emissions, railroads are competing successfully with truckers because they use one-third less fuel. “We’re finally making money and can put it into infrastructure,” the CEO of Norfolk Southern said. No mention of high-speed rail, though. (Source: Greenwire)

New report touts efficiency as best way to cut energy demand
The most economical way to cut growing energy demand and reduce greenhouse gas emissions is to get more productivity from energy, says a report from the McKinsey Global Institute, released last week. Until now, the emphasis has been on increasing supply. The report “identified huge opportunities to reduce energy demand and carbon emissions through efficiency,” Diana Farrel, director of the Institute told Reuters. Squeezing waste out of industry and cars could cut the growth of demand in half from its current 2.2% a year. It would require an initial investment of $170 billion a year, but would pay for itself in savings, the report said. (Reuters PlanetArk)

Nuclear developers drawn to South, despite energy surplus there
Fifteen of the 21 filings for new reactors before the Nuclear Regulatory Commission are for sites in the south, despite the fact that many natural gas power plants there are idle much of the year. Attracted by the prospect of future growth, and possible state incentives above and beyond generous federal tax credits, the utilities are ignoring the fact that existing plants can meet the region’s needs for the next 20 years, critics say. There’s also the issue of cost overruns. Entergy’s Mississippi customers are still paying $12 a month for overruns at a 20-year-old plant. Utilities don’t like the high, and fluctuating, cost of natural gas, but the price of nuclear reactors has skyrocket 200% since 2000, according to Cambridge Energy Research Associates.

Envirocab hybrid taxi company rolls out in Arlington, Va.
A taxi company that bills itself as “carbon negative” has started with 15 hybrid vehicles in the Washington, D.C., metro area. It will buy offsets from Carbonfund.com to counteract the emissions it does release -- and then some. The company aims to have 50 hybrid Priuses, Camrys, Escapes and Highlanders on the street by the end of March. The cabs will help Arlington County meet its goal of reducing GHG 10% by 2012. The county also bought Priuses for one-third of its fleet. (Source: Associated Press)
