Fuel Economy
Nothing contributes more to global warming that CO2 emissions from our vehicles. Americans love their cars, and today they are bigger and faster than they’ve ever been. According to the Federal Highway Administration, there are 241 million cars and trucks on the road in the United States, 53% of which are trucks, vans, SUVs, or minivans. The United States accounts for 30% of the world’s automobiles and require 8.2 million barrels of oil a day to operate them. That’s 11% of the world’s daily oil consumption. All that fuel we burn fills the air with 1,300 million tons of CO2 each year.
The impact this has on our planet is immeasurable. According to the United Nations Human Development Report released in November 2007, the automobile sector accounts for 30% of the greenhouse gas emissions in our atmosphere. Greenhouse Gas emissions are what cause global warming and put our planet, our futures, and the life’s of our children in great danger. The average fuel economy in the United States is 20.2 miles per gallon, compared to 35 mpg in Europe. The reason why is we love our trucks and SUVs, which only average 18 miles per gallon. Compare that to a Honda Civic at 36 mpg or a Toyota Matrix at 33 mpg, its easy to see why we burn so much fuel. Not to mention you can save a lot of money if your car has high fuel economy. Let’s say you drive 20,000 miles a year. At $4 a gallon, if your SUV gets 18 mpg compared to a 35 mpg car you’ll spend $2,159 more on fuel every year by driving an SUV. Another option is to purchase a Hybrid, which you both electric power and fuel.
Solution? The solution is to change what you drive and how you drive. The average fuel economy in the United States is 20.2 miles per gallon, compared to 35 mpg in Europe.

HYBRID CARS
A Hybrid car runs on gas AND an electric battery. They work together so the car gets very high fuel economy. The battery powers the car at slower speeds, and the gas engine powers the car at higher speeds or in times of acceleration. The Honda Civic Hybrid gets 45 mpg city and the Toyota Prius Hybrid gets 48 mpg city! Are they more expensive? At the moment yes but… the government offers tax credits at the state and national levels for people who buy hybrid cars. Those tax credits along with the savings on fuel recoup those high costs in less than two years.
ELECTRIC CARS
Automakers, such as General Motors Corp and Toyota Motor Corp, are planning to bring rechargeable vehicles to the market as early as 2010. But speakers at the Plug-In 2008 conference say it will take much longer for them to arrive in mass numbers, due in part to a current lack of large-battery manufacturing capacity. Auto and battery companies are still working on the lithium-ion battery technology needed for the cars, and on how to link the battery packs to the vehicles. Since most electric cars will likely be charged during off-peak electric use times, utilities should have no problem generating enough electricity. But since people with the means to buy electric cars likely will live in the same areas, utilities worry about stress on their distribution systems. The good news is once electric cars are readily available, its much easier to generate electrical power from renewable sources. So if we all drive electric cars that consume electrical power generated from wind, solar, and geothermal sources then we’ll be on the right track.
