Onshore wind projects have been commissioned with a projected 20 year lifetime. Here in Portugal the companies working in the business are saying that the infrastructure will surely last much more than this, although large they are simple in concept and don't show signs of degradation after more than a decade of operation. Changing the gearbox oil is essentially all the service they need.

The big dependence of fossil fossil is during the erecting stage, after that things go relatively smoothly. Farm operators say that a wind farm is easier to maintain that a solar farm that often requires cleaning.

As for offshore I'd say it might be too early to have a good idea of what the maintenance will be.

None of the solar/wind stuff will last even 20 years. When the highways fail due to a lack of maintenance, which is due to VERY expensive oil, then we can't maintain the power grid, and down goes Humpty Dumpty.

Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the king's horses and all the king's men
Couldn't put Humpty together again.

And the wind/solar stuff just generates electricity, which we now have plenty of, as the malls, stores, airports, and factories are closing.

There is tons of scientific data to show all of this, but most of the conference participants and folks on this site apparently have not read it.

Most of us will live to see the whole shebang collapse, and then we can look at those useless solar panels and wind turbines sitting idle, after wasting much fossil energy in their manufacture, production, distribution, and maintenance. They will be a permanent monument to our collective stupidity!

Oh, do you say electric transportation will save the day? Too late folks, Peak Oil is here today.

Oh, do you say algal diesel? Sniff sniff, er... I smell gas.

It is time to think about Surviving Peak Oil, instead of trying to squeeze more energy out of Mother Earth.

Morning Cliff,

Sorry you're grumpy today.

When the whole shebang collapses I'll come around and collect those worthless solar panels from you. I'll have to use the electric car, hard to carry panels on a scooter. Grid going down? 40 years of electricity from those panels should serve me well. It may look like the panels are just sitting idly, but they'll be working.

Various electric gizmos should be cheap, and I'll have enough panels to do just about anything I please. Heck, I could just sit around making Hydrogen.

Batteries aren't so great but they are optional, and I read some good stuff here about long term storage of battery components. Pull the crap out of your basement, mix together, and voila, more batteries.

I'm not sure why you're so down on viable personal solutions. Highways and the grid? Who cares, maybe it will be nice to have them gone, I'm not going to fight to save them. I'll be at the beach enjoying Mother Earth's free wave energy.

Cheers

And just what will you do with electric power without the grid?

When the highways fail due to a lack of maintenance, which is due to VERY expensive oil, then we can't maintain the power grid, and down goes Humpty Dumpty.

Oh, Woe, if only it was possible to invent a more energy efficient means of transport than road and vehicles powered by internal combustion engines, as the fact that any more energy efficient transport system is physically impossible has such dire consequences.

Would you mind sending over your resources to me if you have given up?
