Renewables: Another Perspective on Energy

Well, we know of 3 oil companies which business they'll be in post peak-oil OR at carbon-neutrality (whichever comes first):

Chevron: geothermal (according to MIT the U.S. has enough for 30.000 years)

Bp: silicon PV solar (silicon is as abundant as sand and dirt cheap if produced from waterglass)

Shell: biofuels, bioplastics, specialty biochemicals (from algae)

No surprises here.

Of course this means lots of work. Lots of drilling and drilling tech fights. Lots of engineering and factories to be build. Thousands of algae species need to be identified or modified. Millions of man-years of software code needs written.
But hey work is fun!

The other oil companies will probably liquidate.

As for nuclear technology: its history.
But enjoy it while it lasts...
