The solar plant that is being built in the Mojave as we speak. Nuclear power plants also avoid emitting most kinds of pollution, although they do have other waste disposal issues.Where is the energy without pollution?
Solar and nuclear power can be scaled up for as much electricity as desired. The primary limitation at the moment is that any powerplant is a serious capital investment that requires a long term view in order to be profitable.What nuclear is being built? Wind mills have been causing health problems. These sources can not supply this country with enough power.
The engine does not 'drive' the wheels. It can 'assist' the electric motor, however.
A hybrid can run on either gas or electric to entirely 'drive' the car. The Volt requires the electric at all times.
According to CNET...
The Volt's engine only 'assists' the actual drivetrain at 70MPH or above. That's a far cry from the implication on blogs like yours.When the battery is depleted, the range extender engine kicks in to generate electricity for the motor, as GM noted in its press materials. But when the battery is depleted and the car is running at 70 mph or above, the planetary gearset transmits additional motive force directly from the engine to the wheels.
We received a call back from GM to one of our inquiries about the Chevy Volt powertrain. Chevy Volt Vehicle Line Director Tony Posawatz explains that the Volt's 111 kilowatt electric traction motor is always driving the wheels of the car when it is in motion. Through testing, GM found that this motor became inefficient when spinning at high rpms, with the car running at 70 mph and above. To reduce wasted energy, GM relied on two strategies.
When the battery has a usable charge, a second electric motor in the system delivers a boost to the planetary gearset, letting the traction motor, which still has the only mechanical connection to the wheels, reduce its speed by half.
Similarly, when the batteries are depleted, the gas engine can take the role of that second electric motor when the car is being driven at speeds of 70 mph. Although mostly working as an electricity generator, it can add its own boost to the planetary gearset under these conditions to let the main traction motor spin at reduced speed.
GM adapted the planetary gearset used in its two-mode hybrid vehicles to realize the goal of the Volt, which Posawatz describes as making "the Volt feel like an electric car all the time."

That was just the first link that came up on google. I can get better sources if you want, but the essential facts are not in dispute.I've heard it, but you are mis-interpreting things, as is the 'blog' you used for a source here.
The important fact is that the engine is mechanically connected the wheels, making it a parallel hybrid. A real series hybrid would have the engine only acting as a generator. Connecting tp the gear-set essentially negates most of the advantages of the series hybrid.The engine does not 'drive' the wheels. It can 'assist' the electric motor, however.
Still, we're better off using electric cars and nuclear/solar/wind power plants. A plug-in hybrid is a good intermediate step, as it combines the efficiency of electric drive with the the range-extension ability of the gas tank. For the daily commute, your power comes from the more-efficient power plant. The gas kicks in for the road trips, and when it does you get a fairly efficient setup. (although still only on-par with a Honda Civic)
Until we get a jump in battery technology that gets us either a rapid charge capability or a 300+ mile range, this type of setup will do.
If we can get them into a reasonable price range.
One of you will end up here next!
what did we miss?
