You bring up so good points, so let's throw in some more.
The technology is improving faster than most people realize. Where electric cars,
photovoltaic cells, and windmills are getting closer and closer to actually being green
when does a city, jump in with investment? One would hope when the romance of the
move diminished by the actual truth of the savings in costs, or carbon footprint. And is
a city is in the middle of budget issues it needs to be for savings not romance.
Some of the gamble can be softened with grants and tax credits and yes even the romance
of turning green. But the gamble is a tough one. If you jumped in on solar panels, you have
lost a ton, as the new stuff is on the market that is 100th the price, and much better in low
light places like Cleveland, London, Seattle, etc. A proper metaphor would be, does a city
invest heavily in 8-track technology, cheaper cleaner cassettes? Beta-Max? VHS? CDs,
Reel to Reel? How many times does a city have to buy the White Album from the Beatles?
If a city is fat with cash, it can afford ever version. However if the city is not cash rich,
it might have to wait till it makes financial sense.
We have not even touched on the real problems currently which is most "green" items
take a larger carbon footprint then they save. So the "green" religion buys into the whole
idea, but the savings are just imaginary. I am not saving "green" is bad or fake, I am just
saying the savings right now rarely adds up to the hype. Still it is noble and a necessary
part of the process to try new technology and help develop new technology, if a city can
afford too. Probably one of the reasons it makes sense for city, and groups to help individuals
invest on smaller levels into the technology, to help test and improve instead of a whole
city or region.

The world's most advanced "mass produced" electric car, the Tesla in Lakewood.

It is based on a Lotus chassis, and I have never read where it is cheaper to run
then the 4 cylinder Toyota powered version.
Or should the city turn to vegetable oil burning diesel? The changeover is being offered by
at least two different groups in Lakewood right now. Or something that runs on methane
or the gases we recover from the water treatment facility?
For Lakewood, right now in 2011 - 2020 it will be where we can save and recoup. Not
sure the city can afford another great cost savings like front yard trash collection!
FWIW
