What is the main idea behind this proposal? What problem does it solve?
An example might be illustrate best. People today can go out and purchase an electric vehicle like the Toyota Prius. Many other car companies make them, such as Renault, Ford, and Checrolet in all car classes from subcompact to pickup trucks to SUVs. There are two main problems for these vehicles. First, as everyone in Hawaii knows- most of our power comes from plants burning Fuel oil and other fossil fuels like coal and LPG. If the power used to charge these vehicles is nothing different, then we have just played a shell game, and nothing has changed. Second- to go any significant distance solely on electrical power, these vehicles must have very large and expensive batteries that can add between $6000 to $20K to the price of the vehicle. It is true that consumers on one hand get a bargain because “gas” for these vehicles is the equivalent of $2.23 per “gallon”, but even though the added battery price pays for itself over 10 years, few consumers will make financial decisions this way.
