Alright, so hybrid cars are supposed to be environmentally friendly because they use both gasoline and electricity. But isn't electricity made with gasoline? And I'm pretty sure you lose energy as you go down the refinement line (i.e. the more you refine something the more energy you lose), so wouldn't hybrids be LESS environmentally friendly and cause MORE emissions?

Or am I a dumbass?

(BTW I don't mean that gas turns into electricity)

The environmental impact of hybrid vehicles is less than a car powered solely by gas/diesel.

Yes, and cows are even better at that. The only reason we're not using cars powered by cow farts is because nobody's figuered out how to attach an air tight box to a cow's behind.

I know energy can't be created or destroyed which is my point. If we efficiently use any other energy besides oil, then why do we try and then waste money.

However I'm completely for researching more efficient means especially solar.
#14
you're half right. Electricity is for the most part produced from coal so using electricity is wasting more energy than gas. The way around this is to use nuclear power for electricity or wind, solar, etc. In the case of hybrids they generate their own electricity by the wheels turning and special brakes. You don't actually hook the car up to an outlet like electric vehicles. This allows the car to run on electricity when going downhill or for cruises down the road, and to switch to gasoline when it needs that extra power to get up hills thus making it more energy efficient.

With hybrid designs the idea is that it takes less gas to charge the cars battery than it does to constantly run a combustion engine, the big difference is that in a hybrid, the gas engine isn't always running, that's why they have low emissions and some of them get up to 70mpg.

To put into perspective what many people have already discussed here, yes it takes unclean energy to power a hybrid. Not to say that all energy produced is from fossil fuels, but the majority is produced by burning fossil fuels.

Hybrid cars are a good idea in theory, but in fact they have a bigger carbon footprint than a Hummer H2. Though you may think that having a hybrid makes you a more "green" person, theres really nothing that has been done to solve the big factor of the batteries. These are the biggest problem of the hybrids. Even though manufacturers state that the batteries are supposed to last 7-10 years, a constant charging on a battery is guaranteed to lessen the life of the battery. Since the gasoline engine runs when the car needs more power or the batteries have run down, the batteries are being charged almost constantly to keep up with the power demands, leading to a battery that has run its course in 4-5 years or less instead of 7-10, like the manufacturer says.

This is why a fully electric car is not very practical. All of the "environmental benefits" of having an all electric car are equaled by the fact that these still haven't solved the problem of helping to reduce emissions. In fact, if there were a dramatic increase in fully electric cars, there would be no observable effect of switching, since all these emissions will either come from a power plant or your tailpipe. Not to mention once all of the batteries in these cars can no longer hold a charge, then you have a big pile up of used worthless batteries that no matter how anybody prepares, will not have the resources to deal all of the recycling that will need to be done.

the electricity used to power the electrical motors is generated by the wheels turning when the vehicle slows down, no?

Most electricity comes from coal, which is a much more efficient source than gas, and doesn't need refining (for all I know)
Plus wind and water are actually widespread,
All of Las Vegas gets it's power from one dam (of course, it's a big dam)

Today the US gets only around 20% of its power from nuclear power. France is around 77%.

Nuclear power is 10 million times as efficient as coal. It could be argued that the energy you get from burning a lump of coal is actually less than the energy you'd get from the extracted miniscule amounts of nuclear fuel based impurities within the same lump of coal.

So a transition to a larger nuclear power source would in turn reduce the carbon footprint of hybrid and electric vehicles.

Yep, many use regenerative braking to charge the batteries, but we might see that change.

Unless you're using "clean" coal it also puts a lot of sulfur in the air.

Exactly, so where the electricity we use in our homes doesn't matter, because you don't plug in a hybrid.

But... the energy still has to come from somewhere. In this case it wouldn't be the kinetic energy of the car? Which came from gasoline? I mean, getting energy from the brakes is a good idea, but does it reduce the net carbon footprint of the whole process?
#34
No, the emissions would be much less because using the electric engine would've give off carbon monoxide.

Your point is valid though, since you would have to use electricity that was probably made by burning coal.

If a car is using less gasoline, then it will have less of an impact.

Obviously Hybrids aren't the answer to the problem, but they're better than what we have now.

ya, getting energy from the brakes only "recycles" energy that would otherwise be wasted

point is, they are "greener" than normal cars, but on the grand scale of things, it won't make a difference

Yep.
And to contribute, a hybrid's gasoline motor doesn't normally kick-in until ~30mph, after the gasoline engine is warmed up, of course.
So, you could save tons of gas by driving under 30 EVERYWHERE, even though that's hardly practical.
