I don't think it is the government's responsibility to tell me how to use my electricity that I'm paying for. If I want a big-ass TV, and I'm willing to pay the associated energy costs, they should not be able to stop me. Same with the "gas guzzler" tax. If I am willing and able to pay additional fuel costs (and additional fuel taxes), then I should be able to use as much fuel as I want.
And, of course, it all blows up when you realize that emissions, fuel consumption, and energy consumption are all directly dependent on the length of time the product is used for. Laws like this don't take that into account at all. It's really simple math - If I watch my 46" LCD one hour per day, and you watch your 23" LCD that uses half as much electricity for 2.5 hours per day, guess who is using less energy.
All of these schemes just reek of being a way for them to tax the shit out of the middle class even more than they already are. If I like cars, and I can afford to purchase a second car that is not fuel efficient to be able to drive on the weekends or in the summer, and I can afford insurance and gas for it, I shouldn't have to pay an additional tax.
At this point, it's extortion. Mention "health" or "environment" in Congress, and your tax is gonna get approved. You can ban whatever you damn well please, or if you can't outright ban it, you can impose huge taxes on the people that buy it. Gas guzzler tax, tobacco tax, alcohol tax, gas tax - none of that exists to make people healthier, or to reduce the use of fossil fuels. It's because you can make a fuckton of revenue creating taxes like that, so we have more money to piss away on failed corporations and deadbeat losers. And it's hard to oppose something like that, because there are a bunch of "holier-than-thou" fucktards who will make you the bad guy.
