I spell out my conjectures.
Scenario | Most Economical Timeframe | Remarks |
---|---|---|
Carbon Competition | 2008-2020 | Cheapest energy sources, except for political barriers |
Conservation | 2008-2015 | Smarter electric grid, better car batteries |
Nu-cu-lar | 2013-2030 | It works, but at what risk? |
Franken-fuels | 2020 and beyond | The most likely revolution |
Solar Singularity | 2025 and beyond | Hope it happens |

If you wrote an article about this at TCS, your link doesn’t go there.

Ah, here is the article.

I strongly agree about hydrogen going nowhere.

No love for fusion? I don’t have a strong enough physics background to guess how likely either ITER or Polywell is to develop into a commercial power source, but neither feels substantially less likely to me than solar singularity, and the projected best cases for commericalization are 2030 and 2020 respectively, which falls within your timeline.

I think that you should look into just how solar cells and Moore’s law might be related
The feature size is what is related to Moore’s Law. The decrease in feature size over time is what drive’s Moore’s Law. Intel is making chips that are 45 nanometers, in contrast to the solar cells at 350. So just going where Intel already is has a lot of potential! And it’s an order of magnitude difference.

Here’s some more background:

The only way I can see Moore’s law having an effect on the photovoltaic market is if there is some efficiency with individual cells being able to handle a certain number of photons, and so smaller cells will have less wasted space.
I really doubt that that is true.
There is only so much energy contained in 1 m^2 of sunlight. Efficiency is around 15% now. It cannot go over 100%.
Now, manufacturing price can definitely go down a lot. But that’s getting further away from Moore’s Law.

Fusion is always a generation or so in the future. It’s a physico-social invariant.

All I will say is there will not be a single solution, but many different solutions operating where they are most advantageous.

At the risk of straying too far from the subject, I think it is worth commenting on how closeley energy use and economic productivity are related. By having cheap, portable energy, we can travel farther and faster when going to work. We substitute large energy consuming farm equipment for human and animal labor. We no longer need to locate factories on waterways because they are now powered by electricity and the necessary labor and materials are transported by cars and trucks. It is more efficient for us to be able to jump in our cars when we want to go somewhere than to wait for the next mass transit shuttle. In short, energy use equals economic productivity.
Looking at energy scenarios from a productivity perspective, anything that drives up energy costs drives down productivity. This includes subsidies, mandates and taxes. It bothers me to read how many of the decision making factors for each of the scenarios are political rather than economic. It bothers me more when the discussion moves straight from the political motivation to whether technology and economics can catch up enough to make the decisions workable. I do not have a problem with the logic in the article. It clearly states the way things are. I do have a big problem accepting the number of non-economic and anti-market factors that drive the choices.
