Sentences with phrase «dioxide than gasoline»

From 2007 to 2013, corn ethanol interests spent $ 158 million lobbying for more mandates and subsidies — and $ 6 million in campaign contributions — for a fuel that reduces mileage, damages engines, requires enormous amounts of land, water and fertilizer, and from stalk to tailpipe emits more carbon dioxide than gasoline.

When you account for these factors, corn ethanol — currently the most widely produced biofuel in the United States — generates about 43 percent less carbon dioxide than gasoline.

Not exact matches

When I ask him what would happen if gasoline cars simply continued to improve in efficiency, he says, «I think people should be a lot more worried than they are,» explaining that even if carbon dioxide levels remain what they are today, we won't feel the ill effects until at least 2035.

This is happening because humans have been producing carbon dioxide (for example, by running cars on gasoline) faster than plants can absorb it, which makes the Earth warmer — and much faster than has happened naturally in the past.

Experts on greenhouse - gas emissions tell me that every time my car burns a gallon of gasoline, I am putting more than 25 pounds of carbon dioxide into the atmosphere as well as a smaller amount of methane, nitrous oxide, and various other toxic gases.

Total annual production emissions, averaged over five years, would equal about 100 grams of carbon dioxide per megajoule — which is 7 percent greater than gasoline emissions and 62 grams above the 60 percent reduction in greenhouse gas emissions as required by the 2007 Energy Independence and Security Act.

It produces less carbon dioxide emissions than coal for electricity or gasoline and diesel for fuel, but even a small amount of natural gas release — which is essentially methane — packs a greenhouse gas punch about 30 times more powerful than the same amount of carbon dioxide.

Another technology that gets better mileage than standard engines, and hence produces less carbon dioxide for each mile driven, is the gasoline - electric hybrid, which marries a gasoline engine with electric motors.

Diesel produces more nitrogen dioxide and particulates than gasoline, so Sweden may have more to gain from small reductions in driving.

Another automotive engine technology that gets better mileage than standard internal - combustion power plants and hence, produces less carbon dioxide for each mile driven, is the gasoline - electric hybrid, which marries a gasoline engine with electric motors.

Writing in the Wall Street Journal, the skeptical environmentalist himself, Bj ¯ rn Lomborg, recently revealed a devastating analysis of the EV's real carbon footprint: «If a typical electric car is driven 50,000 miles in its lifetime, the huge initial emissions from its manufacture means the car will actually have put more carbon dioxide in the atmosphere than a similar - size gasoline - powered car driven the same number of miles.»

The Zafira and Combo CNG (Compressed Natural Gas) produce almost no soot particles, 20 percent less carbon dioxide than a comparable gasoline model and an up to 80 percent reduction in other harmful emissions.

The gasoline also did contain some hydrogen that burned to form water, so the 3:1 ratio Jeff references probably was for gasoline (not containing ethanol) but adjusted for the mass content of the hydrogen in the gasoline and is likely more accurate than the 3.67 ratio of carbon to carbon dioxide masses.

Moreover, even when emissions from the generation of electricity (upstream emissions) were considered, electric vehicles produced 21 times less carbon dioxide equivalent emissions per year than their gasoline - powered alternatives.

For a preview of what this could mean to American families, one can look to Germany, where due to restrictions on carbon dioxide emissions, electricity costs three - times more than in the US and gasoline is now $ 8.00 per gallon.

According to Dr. Laura Iraci of the Earth Science Division at the NASA / Ames Research Center, one hour of TV watching produces 54 kilograms of carbon dioxide, which is more than the 11 kilograms of carbon dioxide produced by burning one gallon of gasoline.

Although diesel vehicles offer lower carbon dioxide emissions and higher gas mileage than gasoline vehicles, some expert scientists, like Stanford University Mark Jacobson, have argued that controlling diesel emissions could be the fastest and «most effective» way to slow climate change.

Not only do you have to mine the coal in the first place, coal liquefaction releases a LOT more carbon dioxide in the refining of a gallon of gasoline than the equivalent process of refining petroleum.
