Hummer owners view themselves as morally upright

(09/22/2009) For many the Hummer has become a symbol of all that is wrong with America: wastefulness without regard to consequences, entitlement beyond the scope of reason, and individualism to the point of arrogance.


Environmental disappointments under Obama

(08/24/2009) While the President has been bogged down for the last couple months in an increasingly histrionic health-care debate-which has devolved so far into ridiculousness that one doesn't know whether to laugh or cry-environmental decisions, mostly from the President's appointees have still been coming fast and furious. However, while the administration started out pouring sunshine on the environment (after years of obfuscated drudgery under the Bush administration), they soon began to move away from truly progressive decisions on the environment and into the recognizable territory of playing it safe-and sometimes even stupid.


Will hydrocarbon biofuels replace gasoline and ethanol?

(08/13/2009) In a Perspectives piece in Science, John R. Regalbuto argues that the world will soon see a revolution in biofuels, but not those made from corn. Instead Regalbuto, program director of Catalysis and Biocatalysis at the National Science Foundation, says that the future of biofuels is in substances that can be converted into hydrocarbons, such as switch grass, woody biomass, corn stover, and even algae.


Obama to increase fuel economy standard to 35 mpg by 2016

(05/18/2009) The Obama administration will direct the Environmental Protection Agency (EPA) and the Department of Transportation to raise fuel economy standards of automobiles to 35 miles per gallon by 2016, four years earlier than required under current federal law, reports the Wall Street Journal. The move is part of the administration's effort to reduce greenhouse gas emissions. Transportation accounts for nearly one third of U.S. carbon dioxide emissions.


Bioelectricity bests ethanol on two fronts: land use and global warming

(05/07/2009) Yesterday the Obama Administration established a Biofuels Interagency Working Group to oversee implementation of new rules and research regarding biofuels. On the group’s first day of work they would do well to look at a new study in Science Magazine comparing the efficacy of ethanol versus bioelectricity.


Obama pushes for better mileage standards

(01/27/2009) President Obama has moved to allow states set automobile emission rules, opening the door for more fuel efficient vehicles. Monday Obama signed a memorandum requiring the Environmental Protection Agency (EPA) to reconsider California's application to set tighter auto emissions and fuel efficiency standards than required under federal law. Should the waiver be granted, automakers would be forced to sell more fuel efficient vehicles if they want to do business in the state.


Tool helps overcome miles-per-gallon illusion

(12/17/2008) A new tool helps motorists evaluate the fuel efficiency of their vehicle in terms that more accurately reflect the cost of driving than miles-per-gallon (MPG).


US government: $28 carbon price would raise gas prices by 25 cents

(10/08/2008) A national carbon price under a cap-and-trade system would have a limited impact on gasoline prices, reports a new study by the Congressional Budget Office (CBO). The report estimates that a carbon price of $28 per ton — a bit less than current carbon prices in the European market — would boost gas prices by 25 cents per gallon, while a $200 per ton tax would increase prices by less then $2. The findings suggest that the cost of climate change legislation may be lower than claimed by industry, but also indicate that efforts to curb Americans' driving habitats via a carbon tax or cap-and-trade scheme may be of limited effectiveness. A $2 increase in the price of gas would still leave U.S. fuel prices well below those in most of the world.


Miles-per-gallon misrepresents gains in fuel efficiency from scrapping worst gas-guzzlers

(06/20/2008) The use of miles-per-gallon instead of gallons-per-distance to measure fuel-efficiency may be clouding Americans' judgement when it comes to choosing whether to take the worst gas-guzzling vehicles off the road, argues a new paper published in the journal Science.


Mutant algae may fuel cars

(04/02/2008) Chemically-modified algae may become key to the production of hydrogen gas which seen by researchers as a next-generation fuel source.


Toyota, GM: Hydrogen fuels cells are not viable

(03/05/2008) Executives from General Motors Corp. and Toyota Motor cast doubts yesterday about the viability of hydrogen fuel cells for mass-market production in the near term, reports The Wall Street Journal. The executives said electric cars will be a better way to cut emissions and improve fuel efficiency.


American demand for gas, big cars begins to wane

(03/03/2008) With crude oil today setting an inflation-adjusted record high, the Wall Street Journal reports that Americans are cutting back on gasoline consumption.


Vehicle-to-grid car generates electricity and cash for owners

(12/04/2007) University of Delaware researchers have created a system that enables vehicles to not only run on electricity alone, but also to generate revenue by storing and providing electricity for utilities. The technology--known as V2G, for vehicle-to-grid--lets electricity flow from the car's battery to power lines and back.


35-mpg mileage target will save consumers $22 billion a year in gas costs

(12/03/2007) The recently passed 35-miles per gallon target for the U.S. car fleet will save American consumers $22 billion a year in gasoline costs assuming an average price of $2.55 according to the Union of Concerned Scientists. However price premiums on fuel-efficient technologies could eat into these savings, reports an article in the Wall Street Journal.


Deal reached on U.S. fuel-economy standards

(11/30/2007) U.S. lawmakers reached an agreement to boost fuel-economy standards of the nation's cars and light-duty trucks for the first time in more than 30 years.


Plug-in hybrid electric vehicles will cut pollution, emissions, oil use

(07/20/2007) Plug-in hybrid electric vehicles (PHEVs) could reduce greenhouse gas emissions and improve air quality significantly by 2050, reports a new study by The Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).


Fuel efficiency boost wins unanimous Senate support

(06/22/2007) The U.S. Senate voted Thursday to raise fuel economy standards for cars and light trucks as part of the new energy bill.


Google to be carbon neutral by year end

(06/20/2007) Google Inc. aims to be carbon neutral by the end of 2007, according to a statement posted on the Official Google Blog. The search giant plans to fight global warming by investing in and using renewable energy sources; reducing energy consumption by maximizing efficiency, and purchasing carbon offsets for the greenhouse gas emissions that it cannot reduce directly.


Google will put $10M towards plug-in hybrid cars

(06/19/2007) Google.org, Google Inc.'s philanthropic arm, today unveiled an initiative to convert hybrid cars to plug-in hybrid vehicles (PHEVs), a move that will cut carbon dioxide emissions, reduce oil use, and help stabilize the electrical grid.


Improving energy efficiency will require overcoming market distortions

(05/20/2007) In a new study, McKinsey&Company, one the world's most respected management consulting firms, reports that the world should be able to cut energy demand growth by half over the next 15 years without compromising economic growth. However it says that market forces along will not drive the transition--targeted policies will be needed to overcome present market failures and policy distortions.


California sues Bush administration over fuel standards

(05/14/2007) Monday California sued the Bush administration for "illegally adopting 'dangerously misguided' gas mileage rules." In a lawsuit backed by 11 states, the suit alleges that the Highway Traffic Safety Administration's new mileage standards violate federal law by ignoring both the environment environmental impact on oil use and the country's growing dependence on imported oil.


Chrysler to launch a hybrid SUV

(04/30/2007) Chrysler will launch hybrid versions of the Dodge Durango and Chrysler Aspen SUVs according to a report from CNNMoney.com. It will be the automaker's first hybrid engine car.


U.S. can cut oil imports to zero by 2040, use to zero by 2050

(03/29/2007) The United States could dramatically cut oil usage over the next 20-30 years at low to no net cost, said Amory B. Lovins, cofounder and CEO of the Colorado-based Rocky Mountain Institute, speaking at Stanford University Wednesday night for a week-long evening series of lectures sponsored by Mineral Acquisition Partners, Inc.


Plug-in cars could help fuel Austin power grid

(03/12/2007) The city of Austin, Texas hopes to launch an ambitious plan using plug-in electric cars to reduce pollution and improve power grid management, reports an article in today's Wall Street Journal. Under the initiative put forth by Roger Duncan, deputy manager of Austin Energy, the city-owned electric utility, and backed by mayor Will Wynn, the plug-in electric cars would serve as sort of giant battery from which the city grid could draw power during peak demand.


US has low-cost alternatives to oil; peak oil frenzy and human-induced climate change avoidable says Columbia University

(05/14/2006) Surging oil prices have fueled calls for the United States to develop new sources of affordable and secure domestic energy. While renewable energy -- especially biofuels, wind power, and solar technologies -- is an area of particular interest, researchers from the Earth Institute at Columbia University say that the U.S. already has relatively low-cost alternatives to imported oil, including coal, tar sands, and oil shale. These resources can be extracted and used at a lower cost to the environment than some might expect. In a report published in the most recent issue of Brookings Papers on Economic Activity, Klaus S. Lackner and Jeffrey D. Sachs argue that "coal alone could satisfy the country's energy needs of the twenty-first century." They say that "coal liquefaction, or the process of deriving liquid fuels from coal, is already being used in places and with expanded infrastructure could provide gasoline, diesel fuel and jet fuel at levels well below current prices." Further, Sachs and Lackner suggest that "environmental constraints such as increased carbon dioxide emissions arising from greater use of coal and other fossil fuels could be avoided for less than 1 percent of gross world product by 2050," a sum far less than others have estimated.
