Fuel vs Electric Cars: The Great Race Begins

The amazing success of the Tesla model S proves that electric cars may have a chance of replacing liquid fueled vehicles in the long run. Skeptics point out that most of our electric power today comes from coal, which is dirty and inefficient. We must change to clean, renewable energy sources but is that really practical? The Tesla has proven that we can use photovoltaic solar power to recharge pure electric cars. Let’s calculate how much land is needed to renewably fuel a car using several possible electrical and biofuel approaches.

I recently purchased a Chevy Volt plug-in hybrid car. It is the perfect laboratory for this experiment because it can run on pure electricity or as a gasoline hybrid. In the electric mode it can go 38 miles on a 10.8 kilowatt-hour recharge. That’s 3.5 miles per kilowatt hour. Allowing for power transmission and charging losses, let's use 3 mi/kWh. I will compare the land use efficiency of several real approaches to renewable power using both liquid fuel and electricity. We will calculate the number of miles per year that can be driven using an acre of land to produce the power. We can then compare the miles/year/acre numbers for some real-world renewable energy approaches
