California to be electric car capital

Officials in California have unveiled ambitious plans to turn the San Francisco Bay area - home to 7,6-million people - into one of the world's leading centres for electric vehicles.

If it succeeds, the strategy will see billions of dollars poured into a power infrastructure that will turn the region away from fossil fuels and persuade millions of people to switch to green transport technology.

The plan, which will see the bay area become the first region of California to switch its transport systems entirely away from traditional fuels, is being supported by local government as well as the state's governor, Arnold Schwarzenegger. "California is already a world leader in fighting global warming and promoting renewable energy," he said. "This partnership is proof that by working together we can achieve our goals of creating a healthier planet while boosting our economy."

Globally, cars generate about 20% of the world's output of carbon dioxide and California's cars account for 40% of the state's greenhouse gas emissions. Replacing around 1-million petrol cars with electric cars by 2015, as is proposed under the new plans, will make a big difference.

At least $1-billion is expected to be spent on improving green transport infrastructure to make the bay area - encompassing the cities of San Francisco, Oakland and San Jose as well as Silicon Valley - the leading centre for electric vehicles in the United States, and potentially around the world.

The electric transportation company Better Place will build a network of kerbside charging points across cities in the area and create the equivalent of filling stations, where electric car owners will be able to replace their flat batteries for fully charged ones.

Types of pollution emitted by gas lawn mowers...

Lawn mowers produce several types of pollutants, including polycyclic aromatic hydrocarbons, ozone precursors, and carbon dioxide.

One type of pollutant emitted by lawn mowers is polycyclic aromatic hydrocarbons (PAHs). These are classified as probable carcinogens by the CDC. Testing found that operating a typical gasoline mower with a four-cycle engine produced as much PAH as driving a modern car about 150 km or about 95 miles. (Note 1). This means that unless you drive more than 95 mph, your mower actually produces more pollution per hour than your car!

Another source claims that operating a gas mower for one hour will produce the same pollution as driving a car 1300 miles. (Note 4)

Yet another source claims the figure is about 3400 miles of car travel per hour of mower use. (Note 5)

In an hour's mowing, twenty-six different PAHs were found in the exhaust of the mowers, including 100microgrammes of benzo[a]pyrenes, which have been mentioned as a carcinogen in cigarette smoke. Other chemicals emitted include half a kilogram of carbon monoxide and several grams of methane, hydrocarbons, nitrogen oxide and smoke particles. (Note 1)

Another pollutant caused disproportionately by gas-powered lawn equipment is ozone. Hydrocarbons from mowers react with nitrogen oxides in the presence of sunlight to produce ozone. Since lawn mowing occurs during the summer months, it exacerbates the already high levels of ground-level ozone present in the summer. Ozone irritates the lining of the lungs and agravates athsma and other respiratory conditions. (Note 1). Ozone is the principal pollutant that causes "Red Alert" warnings about air quality in the summer.

An EPA study found that approximately 9 percent of some types of air pollutants nationwide come from lawn and garden equipment small engines. (Note 1) In metropolitan areas, the concentration of lawns causes this percentage to increase, in some instances to 33%.

The author of one pollution study had this to say: "Using a catalyst would help prevent most emissions from small engines. Of course, people could also use an electrical powered lawn mower instead." (Note 1.)

In Britain, more than 70% of lawn mowers sold are electric. (Note 2.)
