It's true that to pay for things we just sort of have to buy anyways, we usually have to earn that much more FIRST, then pay our taxes, and then pay for the thing that is more or less a necessity.

I was running some numbers on financial ROI (return on investment) of a 5,000 watt PV photovoltaic solar system. While people have generally thought of solar as expensive, using it to power an electric vehicle really brings down the cost and speeds up the investment return.

For example. If I drive 1000 miles a month in a 25 MPG car, that's 40 gallons of gas per month, 480 gallons per year. At $2/gallon, that's $960, at $4/gallon, that's $1920. But if you are in a 30% tax bracket, you have to earn $2742.86 to buy that gas.

The solar system I'm looking at would be $10-$12,000. Minus various incentives, it could get down as low as $6,000. $6K/$2742.86 = 2.187 years of fuel.

So, seriously, in what a person spends in fuel, you could buy yourself a solar system and drive an electric car - FOR FREE.
