Our Energy Predicament: In Charts
Gail Tverberg | Mar 13, 2013 03:12AM ET
A friend asked me to put together a presentation on our energy predicament. I am not certain all of the charts in this post will go into it, but I thought others might be interested in a not-so-difficult version of the story of the energy predicament we are reaching.
My friend also asked what characteristics a new fuel would need to have to solve our energy predicament. Because of this, I have included a section at the end on this subject, rather than the traditional, “How do we respond?” section. Given the timing involved, and the combination of limits we are reaching, it is not clear that a fuel suitable for mitigation is really feasible, however.
ENERGY BASICS
Energy makes the world go around
Energy literally makes the world turn on its axis and rotate around the sun.
Energy is what allows us to transform a set of raw materials into a finished product.
Energy is also what allows an us to transport goods (or ourselves) from one location to another. Services of any type require energy–for example, energy to light an office building, energy to create a computer, and human energy to make the computer operate. Without energy of many types, we wouldn’t have an economy.
Increased energy use is associated with increasing prosperity.

Energy use and oil use have risen more or less in tandem with GDP increases. Oil is expensive and in short supply, so its increases have tended to be somewhat smaller than total energy increases. This happens because businesses are constantly seeking ways to substitute away from oil use.

China is an example of a country with very high growth in energy use. China’s energy use started growing rapidly immediately after it joined the Space solar theoretically would be much better, because it is much more sparing in its use of resources–it would have over a 99% capacity factor, and the PV film could be much thinner. Timing for space solar would be a big issue, however, assuming financial issues can be worked out.
Also, even if space solar or some other fuel should provide the fuel characteristics we need, we still need to address the population issue. As long as world population keeps rising, humans are an increasing strain on earth’s resources.
