Electric -- the technology is already here
Electric cars are the obvious choice.
Interestingly, electric cars were among the earliest vehicles on the road ... they were around in 1913, before internal combustion engines became all the rage.
The only reason that technology didn't get a foothold is because there has been a collusion of government and oil industry interests to keep oil has been cheap all these years --- a situation that is obviously rapidly changing with the rapidly rising price of gas.
The excellent documentary "Who Killed The Electric Car?" vividly documents how GM had a really great electric car on the road in the 1990s and then deliberately killed it ... refusing to let customers buy their leased vehicles and forcing them to give the cars back so that they could be sent to the dump and crushed.
Those cars, which could be recharged in your garage, had a limited range of about 60 miles before needing to be recharged ...
So, OK ... you couldn't go across the country with them, but they were just fine for in-city commutes ... the normal things most people use cars for: going to work and back, going to get groceries, etc.(and imagine: no gasoline fuel fillups for this!)
Now, GM says it it is resurrecting the electric car ... after losing years of momentum on that front. Yeah, I'm not impressed.
Meanwhile, great strides are already being made to develop much, much better batter batteries. We already have technology being developed that would greatly extend the range of electric cars. I personally don't think it would be hard to extend the range of an electric to 100, or even 200 Km.
So where will the electricity come from? Well, it is already technologically possible to build wind-generated plug-in stations, with the power coming from the wind turbines that feed the energy into the electricty grid. There are also great strides being made in solar energy production and batteries recharged by solar panels, so a combination of wind and solar could produce the energy needed.
The only thing stopping the progress is that politicians are too friendly with the oil industries. But if we made a concerted effort to vote out those politicians, I think zero-emission electric cars could become the norm within five years.
