The long term solution is cellulose based ethanol. (Cellulose is nothing more then polymerized sugar. If you could break it down back into sugar...) The problem with this solution is that up to now, the proposals have been nothing more then laboratory experiments and prototypes. This year, actual production facilities are being built, and it remains to be seen if they can actually meet their estimated costs of production under real world conditions...

How about tidal power where energy is produced as the tides move ina and out by spinning turbines. From what I've read and talked to others about, France uses it on their Mediteranean coastline. I think several other countries do to. What I don't understand is why we here in America don't use it.
Then there's also a plant in Arizona that burns used tires for energy. From what I've read, it produces enough energy to poer one or two cities.
Tidal power, from what I have heard, it can produce a great amount of energy but it also has the possibility of causing massive disruption to the local environment in the way in which it is done. During construction as well as during it life, fish migration other wildlife, the natural movements and flows can be greatly disrupted/ destroyed. .
Which is a shame because it would be a real option considering the amount of energy it would create
The way I read it is that they bury the turbines deep in the ocean with grates and the like. They have it now to wear it causes very little impact to the undersea environment. At least that's what I've read. Not sre if it is to that point already or not, yet. If we put both environmentalist and engineers working together on it, I'm sure that it could be done. I also forgot to mention that Lake Erie can be a source of tidal power.
Your talking about off shore turbines right? I can see how they would have an affect any where they are placed - particularly during construction phase. The other is Tidal Barrages, which by the looks would have more of an impact on the environment (info)
Maybe as time goes on we will have something better, but at the moment it doesn't seem to good compared to other renewables.
Yeah. Initially, they'd have a great impact on the system, but with careful placement and proper construction, they would be alot better for the environment than the plants that use fossil fuels and not as dangerous as some nuclear plants. From what I learned in my Environmental classes, Perry Nuclear Plant is situated on a faultline several cities over and the elctricity it produces isn't even used in the area.
I was also thinking of their placement in areas where the natural ecology has already been disturbed ruined.

Tidal Power actually has even less viable locations then Geothermal power. What is the average difference in height between high tide and low tide? (6 feet?, 12 feet? How many Hydropower dams do you know of that are only 12 feet tall???) And capturing and diverting the high tide in significant amounts is bound to have environmental consequences for fish migration and habitat.
What might be a more viable solution would be to harness the power of Waves. The major issue with both is that locations with either strong wave or tidal power potential are usually far away from where the power demands are....
