As far as environmentalists helping create the disaster...turn that finger around and point it right at yourself. WE ALL helped create this.

Using renewable sources are great but one has to look at the locations and the disadvantages of using these renewable sources of energy.

Wind- only in areas where wind is steady
Geothermal- only in areas where it is not too deep and close to the surface and the rock to drill through to the source is drillable (is that a word). Over 90 % use in Iceland which is awesom.
Ocean currents- location would be in estuaries and the turbines used can disrupt and destroy wildlife and the habitat.

It's really not that easy for those three.

The thing about ethanol and biomass is that they also produce greenhouse gases when burned but they are renewable. I think when they suggest to use them they only look at the renewable aspect.

Some of your information is incorrect.

Wind - yes, wind farms need to be in places where wind is steady. This includes all along the coast, all across the plains, on the tops of hills and mountain valleys, and offshore. That's a whole lot of area.

Geothermal - you do not have to drill into rock to access geothermal energy. It is most efficient at plate boundaries and active volcanic areas, but you can use geothermal energy anywhere. I could install a geothermal heat pump in my house if I wanted to. Geothermal exchange can be used to cool a home as well.

Ocean currents - why would they only be used in estuaries? I'm not talking about local fluvial currents, but surface and deep water currents in the ocean. I imagine the sedimentation rate would be too high to run turbines in a typical estuary, not to mention the currents are nowhere near as strong as those in the ocean.

It is that easy. The problem is that so little money and time are devoted to developing these technologies that they are advancing at a snail's pace. There's too much money to be made in natural resource reserves, and greed is what makes the world go 'round.

Eta: if they replaced all of the offshore oil rigs with wind farms, they could produce a heck of a lot of energy. Just sayin'...

OK, gotta play the devil's advocate here...

many folks moan and groan about the gov't interfering with businesses and such...just look at the outcry during the financial crisis.

Now, we have an environmental crisis and the gov't is doing what it can...and, make no mistake, this is a BRITISH-owned firm. They (the gov't) do not have the same amount of leverage...especially since the company is NOT asking for handouts and, is instead, paying out the money. Still, people moan.

WHAT DO YOU WANT, PEOPLE?? Now, do I think that BP has done enough?? Absolutely not. Do I think that BP cares a bit about OUR shores or OUR people?? HECK NO. But, they are not fouling THEIR country, so, why would they? But, HOW IN THE WORLD can a US gov't do any more than what they are doing? They are holding BP's feet to the fire to try to force them to do more; all the while dancing that delicate PC dance with a new prime minister in Britain...

Bottom line, if the US gov't did any more, it would appear as an American gov't takeover of a privately owned (foreign) business. Now, all those that are terrified of the whole socialism thing would have coronaries and take to the streets screaming and yelling. Not to mention that we would make permanent enemies of an ally.

This is a very delicate area that we are in...and, I am not talking just environmental.

Thanks for the links. They corroborate my facts exactly. Hopefully people who don't know the information can take something away from them!
