When you must expend 100 Joules of energy to extract oil that will yield
less than 100 Joules of energy, the politics doesn't matter, the economics
doesn't matter. You are at the point where you are better off to use the
100 Joules directly and not convert it into crude petrolium.

What about waste heat, you might say. What about heat left over after you
burn fuel to make electricty?

When you convert heat into useful energy, the amount you can convert
depends on your starting and ending temperatures. When you try to use the
'waste heat' you decrease the power out of the generator. You can use SOME
of the waste heat to do useful things, like recover oil from oil shale, but
I was already considering that in my original statement.

Assume we are already making the best possible use of all of our energy
resources, you eventually (and that day is closer than you think) reach the
point where it takes more energy to extract energy than you have available.
Tech improvements will not solve this problem.

Again, better to move our industries into space. There, if you want more
energy, you use a bigger mirror.

And I disagree strongly with you about this.

NO! man would increase the sea level rise by speeding up the melting of
glacers and the southern ice cap. It is already happening.

Where do you think the sea level rise we are seeing is coming from?

DDT has stopped being useful in areas where they continued to use it.

We will have to agree to disagree on many things.

Have the best of all possible days. It is a beautiful day to be alive,
isn't it? Every day.
