Within a single century, personal transportation has progressed from the horse and buggy to nearly a billion private automobiles. It is projected that the need for personal mobility will grow even faster, as large numbers of people are lifted out of poverty in developing countries and demand transportation. Life in developed countries is unimaginable without the car, but our current vehicles depend on oil. The age of oil is quickly ending.
By many accounts, civilization has already used half the world’s oil. Remaining reserves are hard to reach and increasingly expensive. In just the last decade, the price for one barrel has gone from $10 to over $130, and shows no signs of stopping there.Emissions from oil-burning automobiles clog our air and contribute to global warming. Numerous scientific studies suggest that a 50 to 80 percent global reduction in green house gas emissions is necessary to stabilize the planet’s climate.
For all of these reasons, finding an alternative to oil for private transportation is imperative. Although several alternatives can propel a car, only one is readily available today. We have a choice that both pick up where oil leaves off and allows us the personal mobility we’ve come to expect: electricity.
