One externality you did not include was the cost of decommisioning different plants and restoring the land. I probably would not have thought about it either, except I talked with a nice man at a swedish environmental NGO. He told me how they had been pushing for all-steel structures (or at least a lot of metal) for wind-power, when swedish concrete giants had wanted to build wind-farm on concrete platforms. The reason for this was that as long as it was fairly pure metals, it would in all probability be worth it to harvest the scrap metal if and when it was decommisioned. Otherwise they might leave concrete plates all over.
Now there was a organisation that was thinking ahead. A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!
The cost of taking them down is not so high on a per turbine basis; you should also expect that in a few years, most useful sites will have been taken, and turbiens will be taken down - to put bigger ones in the same, already approved, spot... In the long run, we're all dead. John Maynard Keynes
Anyway that is good news, but I was actually more thinking of possible lingering environmental effects from nuclear and coal plants sites. I do not know what they might be, but I guess the dismantling of Barsebäck here in Sweden might give a hint.
If there are such effects it would of course push the calculus in favor windpower. A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!
Why can you not store electricity? Do the plants always produce 1-to-1 with the demand? A patriot must always be ready to defend his country against his government -- Edward Abbey
If someone invented a room-temperature superconductor, it would eliminate distribution losses and could potentially also be used for loss-free storage. But current superconductors need super cooling, so they use more energy than they could possibly save.
This storage has to stay safe for 100,000 years or so, so it won't be cheap. There are very few places on the planet that are dry enough and stable enough to make reliable storage possible. And the costs of creating inert containers - the current favourite is a copper/steel mix - aren't trivial.
So when decommissioning costs are quoted, it's worth remembering that they don't yet include this long term storage.
Now, considering that is looks more like a dirty, salty puddle, the base had to be relocated, due to safety reasons.
Funny, but the island was a state-protected national park back then. Almost no wildlife there now, is there? A patriot must always be ready to defend his country against his government -- Edward Abbey
Don't read it, you gonna be sick for at least a day. The struggle of man against tyranny is the struggle of memory against forgetting.(Kundera)
A couple of years ago I watched a Russian documentary about the island, in which they showed the bunkers with the stuff that were some sort of storage facility. A patriot must always be ready to defend his country against his government -- Edward Abbey
So I am not convinced that there is no solution to the waste problem. I personally think that it plays on our fears of an invisible killer more than anything else. There are lots of things that are really more dangerous to us and which we should worry about before (like most pollution from coal...) In the long run, we're all dead. John Maynard Keynes
Another way of looking at opportunity cost is that natural hydrocarbons are hard to make and are much more useful as chemical feedstock than as fuel. So by burning them now we can expect higher costs for synthetic materials later.
As non-renewable resources it is also hard to calculate the cost to society after they run out. Currently the way this is handled is exactly backwards. Extraction industries get a tax break for using up natural resources (depletion allowances) instead of being charged for permanently removing them from the commons. Standard economic models always assume substitutes will exist for any commodity. Which implies that the fuel costs of Uranium will rise so that the effective cost per KWh will tend to be the same as with other fuels. The differences in the cost of power generation by technology used are mostly because the marketplace hasn't had a chance to catch up with the new raw material situation.
While no profit making company is going to factor in the opportunity costs or the long range ecological costs when making business decisions, governments can do this via tax and other public policies. Unfortunately there is hardly any real long range planning being done outside of academia. I've coined a new acronym. We have NIMBY (not in my back yard) to express the unwillingness of people to allow new developments. My new one is NIMLT (not in my life time). People are unwilling to make any changes in their lifestyles and push the sacrifices needed into the future. Policies not Politics ---- Daily Landscape
If we had a power plant on every block, and the fuel could be transported more efficiently than electricity, we could double our supply for the same fuel/carbon cost.
Now, who wants this down the block? (Don't all raise your hands at once)
Whether or not it makes sense to install small turbines on rooftops seems to be controversial, but I see no reason why you couldn't install a 10m tower on a 3-storey building spanning a city blosk. It wouldn't look disporportionate either. guaranteed to evoke a violent reaction from police is to challenge their right to "define the situation." --- David Graeber citing Marc Cooper
