There is always a reason why some things never change. At least they don't change for the better. As an example in Europe, Asia and in South America also, there are Fords and Toyotas that get over 70 MPG on the highway. None of them are sold in the United States. And it's not because they are not safe vehicles. They are the same vehicles sold here but with much more fuel efficient engines. That's right, they are made here in America, but for export only.
Someone researched this "rumor" only to discover that not only was it true, but that the reason given is really based on half-truths, smoke screen, for the truth. More fuel efficiency means the care can go further or create more horsepower using less fuel. This means less fuel is sold and a reduction in revenue for the government. See, "under the guise of cleaner air," the EPA claims that the more fuel efficient engines produce more pollution per gallon than their US-sold counter parts. But the facts are such that those foreign-sold engines, because they burn less fuel per mile, will produce less pollution over the same distance than the US-sold engines..
No, the reality is that our government wants more of our money, so they create all of this hidden tax that most people pay without thinking about it. When it comes to the price of fuel, they blame the "greedy oil industry" or Wall Street speculators. That is because the media reports such drivel as the government spins-out to the public.
Same thing with the electric car. If just 20 percent ofall American vehicles driven here in America were all electric, the federal government would lose hundreds of millions in revenue currently used to build, maintain, and repair the nation's highways. Now that part may be partially true, but it does not tell the whole story.
Less exhaust fumes in the air will allow people and wildlife healthier lives. That in itself will reduce the cost to treat the sick, who are availing themselves of taxpayer funded medical resources or programs. The roads themselves will retain serviceability longer since the pollutants that settle on and damage the roads will be greatly reduced. Businesses and commuters will spend less on fuel and that will mean they can have more revenue of their own! Imagine that! you could then afford to drive to your vacation spot and still have money left in your wallet to really enjoy it!
As more and more reasons become apparent for solar and wind energy, they too will supplement the fuels used today that will further reduce the pollutants in environment. It may even provide more incentives to install solar and wind power generating systems and that will mean manufacturers in the US will be able to compete in those markets.
I can see the technology being refined to introduce more efficiency and power output as the demand for these systems increase.
An international effort to cut so-called greenhouse gases by imposing taxes and caps on how much GHG you can exhaust before paying is not going to solve anything, in fact the so-called carbon tax is nothing more than another taxation boondoggle. All it will do is make the world poorer and the investors in the Cap & Trade program much wealthier. That will increase the polarization of haves and have-nots. The intent is, of curse, reduce the world to the slaves and masters or the situation of those who must depend on the state for rations and those who will live in opulence and splendor as they continue to look down on the rest of us as if we were their property.
Wake up people! You're running out of time!
