Open Your Wallets: Just in case you have money burning a hole in your pocket, Tom Konrad over at AltEnergyStocks.com is sharing his picks for the Top 10 clean enegry stocks he's adding to his portfolio. Three companies hail from the geothermal segment, while several others play in the technology intersection we at GreenBiz call VERGE, which includes energy, information, buildings and vehicle technologies. Comverge and EnerNOC are demand response companies, while CVTech Group dabbles in electricity transmission and efficient vehicles. Another company, Ambient Corp., focuses on smart grid technologies.

All Aboard: Eurostar, operator of high-speed trains running between London, Paris and Brussels, plans to shrink its carbon railprint by a quarter by 2015. As Will Nichols from BusinessGreen.com reported, the company will abandon carbon offsets in favor of a more comprehensive sustainability strategy focused on direct emissions reductions. Eurostar previously offset its customers' journeys but found that customers either didn't understand the company's goals or felt the benefits from the offets were too far in the future.

Ethanol on the Ropes: The U.S. Senate voted to terminate a tax credit and tariff for the ethanol industry Thursday, which could be the first in a string of energy subsidies that will end up on the chopping block. The vote ends a 45 cent per gallon tax credit and 54 cent import tariff, which largely blocks ethanol imported from Brazil. "I think the days of large subsidies like this are really over, and this is kind of the first vote on it," said Sen. Dianne Feinstein (D-Calif.), who sponsored the subsidies amendment with Sen. Tom Coburn (R-Okla.), Politico reported. "I think you're going to see all kinds of subsidies go, because we've got so many problems."

High Cost Estimates of EPA Rules Overblown: Contrary to the dire predictions that greenhouse gas rules from the U.S. Environmental Protection Agency will exact huge costs, a new study finds the price tag will be minimal -- at least in the early phases. Instead the new rules will encourage what power generators and refineries are already doing: investing in energy efficiency, according to the Bloomberg Government study. "The rules don't change industry behavior much from business as usual," Rob Barnett, a Bloomberg Government energy analyst, told Bloomberg News. "It's a rubber stamp on what companies would do anyway." 

I'm Moving to the UK: New research from the U.S. National Center for Atmospheric Research (NCAR) suggests the North Atlantic will keep temperature rise in the U.K. in the range of 2 degrees to 4 degrees, while North America could see an increase five times greater over the same period, the Independent reported. The urban heat-island effect from buildings and roads, however, could lead to more hot summer nights in big cities like London.
