One of the costs of solar power that isn't usually mentioned is pollution from manufacturing all those solar panels. Making photovoltaic cells is a pretty nasty process, from what I've heard.

Of course, all the excessive industrial polution in the world will eventually reap disasterous results. Like giant lizards emerging from the waters off shore of Tokyo. You know, "Time shows us again and again, how nature points out the folly of man."

GO-GO-GODZILLA!

Let’s note a few points here. Hydrogen is the energy in gas oil and coal. So we have quite a lot at the moment, all we need to do is change the way we refine it. And in so doing, we can contain the carbon, sulfur and other impurities. So we can deploy cars with fuel cells. Add to that some advancements in superconducting magnets and storage batteries, and you could have a workable car. But that won’t solve the problem! What it comes down to is that there are just too many cars in the world. And that brings us to the problem of too many people in the world, a problem that will never be addressed. So, we will continue to consume everything in sight until it runs out. Here in the developed world we will spend on technology and try to hold the line on the damage we do. All the while, the developing world will continue to increase their out put at a rate that far exceeds our reductions. So in the end, we will continue to screw it all up until something runs out. Then there will suddenly be a lot less people.

I just read this one site about fuel cells, and they suggest that a fuel cell vehicle will produce less water than a gasoline vehicle, so the fears of "water pollution" causing problems in cities is unlikely to occur. The site did note, though, that the water vapor was colder than in a combustion engine, so it might not be absorbed in the air as much.

As for the comments about it taking fossil fuels to create the electricity to extract hydrogen from water, that appears to not be an issue. Most of the hydrogen fuel cells being examined right now are using fossil fuels (oil, natural gas, methane) to produce the hydrogen, and as such you do gain energy in the process. (btw, the only thing that such a fuel cell produces is water and CO2. Personally, I don't think the world needs to worry about CO2 production, but that is a topic for another debate (: ).

Oh yeah, here is the URL for the website I was reading: http://www.fuelcells.org/fcfaqs.htm#from

Promote vegetarianism. It takes far less power to produce fruits and vegetables than it does to produce an equal supply of nutrieants in beaf / pork / chicken.

Cook as little of this food as possible. Cooking destroys a lot of the vitamens in food.

People do not get fat from eating meat. They get fat from eating too much food and not excercising enough. Becoming a vegetarian alone will only cause you to lose weight if you don't get enough protein supplements so that your body can maintain its muscles.

It is actually easier to lose weight while not being a vegetarian because your body uses proteins when it breaks down fats. Eating more proteins and excercisng is how you lose weight.

Those fruits and vegetables lack a lot of necessary nutrients that are only found in animal products, and some very specific types of vegetables. But, you have to eat more of those vegetables to get the lacking nutrients than you'd need for an equivalent amount of animal products.

Most of the land used to graze cattle on is useless for other farming because of low nutrient and water levels.

Further, humans are meant to eat meat, and can only survive without eating meat by eating a huge amount of the few vegetables that contain the amino acids we can't synthesize.

Oh, wait, one more:
Get rid of SUVs!!!!

You are aware that there are perfectly legitimate reasons to own them?

Except those are useful for other things. Much easier to use seawater. It's plentiful, it has lots of hydrogen, and the techniques needed to seperate the hydrogen are easily done. (this is also why fusion is an attractive energy source)

Run electricity through some water, it separates into hydrogen and oxygen.
