one is accidental and one is on purpose for starters.

Either way it's a bunch of bs! If that hits the coast it's going to be horrible!

Im not going to get into politics and im not trying to stir anything up one way or another.
this is a sad situation for sure, but what everyone must remember is all energy has a cost. whether its nuclear plants, coal plants, natural gas plants, electricity, batteries, gasoline, oil, anything. it all has a cost and most of it has an environmental cost or something that involves people dying. think about the coal miners that died a few weeks ago. they were mining coal to burn to make electricity. these guys working this platform where getting oil for cars. both accidents were caused by the worlds hunger for energy. and until someone can figure out a way to produce energy a different way, nothing will change no matter whether they are democratic, republican, or independent.

You know its funny you mention those 3 other sources. i was talking about them to a guy yesterday. hydropower is a good source of clean, renewable energy. but the problem with it is its not dependable. one year it rains alot and the next year its a drought. so its hard to depend on it all the time. tva uses it when they can and when there is sufficient rain. but i agree its one of the best ways of generating clean power. you just cant depend on it to power entire cities year round.Bfish - 4/29/2010 7:29 PM
Point well made. However you did not mention hydropower, wind, or solar; all which have lower cost (IMO). Also their is something that we all can do and that is just plain use less. Conserve energy is not just about energy, it is also about conserving resources and providing for a less bleak future. Okay enough of the soapbox.
Sad thing about the oils spill is it will happen again.

Good Post \TritonAL
No to mention the 11 lives lost and the 11 families + all the friends that are grieving.
Sure you can, you just have to build more facilities to generate. Even during a drought year water is still water that is flowing, and TVA (and other utilities) are still generating hydropower, just not as much as wet years. Some of the newer hydrokinetics don't even utilize dams, just the current. Hydro is very dependable, their is a reason that utilities use them as a backup to for their nuclear, coal, oil/gas fired plants. If one of those go offline it maybe hours before they get it back up and running, while in the meantime in a matter of minutes a hydropower plant can be up and running.jim4596 - 4/30/2010 8:15 AM

Yeah wind is not cost effective when compared to oil/gas/coal but the environmental cost is way lower. When compared to other "green" energy wind is competitive cost wise, even without being subsidized.as for the wind. its just not there yet. i was talking to an exec at a large power company up north last week. and he basically told me that if it were not for the government subsidies, his company would not be building the wind farms. they are popular right now. but the government is subsidising their construction. they generate approx 1 mw and cost about $1M to build (not counting their maintenance costs). government is chipping in about $600k of the $1M. also their are some issues around them locking up and when they do its not an easy fix. the power companies are just using them as a smoke and mirrors type of thing. in other words when they have them they can carry on with how they are producing "green power." i think tva has a deal now where you can sign up and purchase green power. it costs you more a month and you are getting the same power that everyone else gets (from a nuclear or fossil plant most likely) because there is no way to separate and provide you with different power than is on the line.
That is true of the 1970's solar, not so much anymore. Solar can go directly to the grid and the utilities are required to buy it. Additionally largescale solar is very efficient, they can uses photovoltaics or mirrors and direct that to a steam plant, to turn the turbines similar to oil/gas/nuclear plant works.solar isnt there yet either and besides, with solar you just about have to use batteries to capture it. and batteries are terrible on the environment when they are disposed of.
Technology is good, but reduction in usage will have more robust and more immediate impact, IMO.so until someone comes up with some new technology to provide energy I just dont see things changing. just my opinion.
