To eliminate the use of gasoline for our motor vehicles is something that many wish for. I have a few suggestions which stem from my engineering background.

1. Eliminate the use of all gasoline (and diesel) engines.

2. All motor devices will be powered by solar cells.

3. There will be no batteries to hold a charge and allow motor vehicles to be used except when there is sufficient sunshine.
A. This will help the environment when it comes time to dispose of batteries.
B. Conduct your business while it is sunny. When it is dark everything shuts down.

Next problem please! :)
