Well, these alt fuel vehicles are good solutions for a temp fix, but the more I think about it the more electric makes sense environmentally anyway. We are going to need to use a renewable energy like... electric?? I'm probably going to start with an e bike of some type myself... using oil is hurting our planet in many ways and it seems to be hurting the economy.
natural gas is a finite non renewable source of energy so we are going to need something sustainable. I can't believe I'm sounding like i own Birkenstock's.... stop me quick!!
