Well Electric makes sense in that
A) Range is not an issue....at all.
B) Top speed (for a car) is not an issue. I don't think any road in Hawaii is anywhere near 75 mph like the landlogged states.
C) While yes the power plants are polluters, well panels on your roof aren't...and Yes, Hawaii isn't New Mexico or Arizona with endless sun and almost NO RAIN, but Hawaii does have sunshine most days, just also has some rain most days
Still you can power your home and your transportation in Hawaii with your roof if you have the funds. And solar is getting cheaper every year...and gas will keep going up.
So....if you have a home on Hawaii....get Electric Vehicles and solar panels.
If you live in an Apt and have somewhat lesser income...go Prius.
If you are really student poor...bike or scooter would be best...or public transportation...but I have no idea about public transport in Hawaii...I've only been to Kauai...though I might be going to a conference on the Big Island next year.
