Review: Ergosphere on Energy
is a blog that's been around for about a year now, touching on roughly the same energy policy topics we've been working on, with some excellent technical summaries of the issues. Thanks to a post on RealClimate
for a pointer!
The author's take on energy issues is a serious and technical one - one particularly interesting analysis is this discussion of the transportation problem
. As he points out, actual energy at the wheels as used in transportation in the US amounts to about 180 GW average; that's an achievable number, well under peak electric capacity. There will be losses in electric vehicles too, but far less than the 60-80% losses in internal combustion engines.
How would we actually make such a switch to electric vehicles? An interesting specific proposal is "Where to Go from Here":
- Step 1: Find the will and the money. He suggests calling it a "war", and a roughly $1/gallon gas tax to raise $100 billion/year
- Step 2: Support other fuels, but only the right ones. Methanol probably better than ethanol.
- Step 3: Use non-chemical energy. I.e. electric. Promoting plug-in hybrids as a component of this.
- Step 4: Get the energy, cleanly. He unfortunately emphasizes coal here, Integrated Gasfication Combined Cycle (IGCC) plants in particular; the one example of conversion with large power increase may not be as replicable as he suggests though. The other emphasis is gas co-generation facilities.
- Step 5: Use renewables where possible. Particularly wind.
He estimates 10 years of this program would eliminate US need to import oil, and more than pay for itself. Perhaps a bit optimistic, but it's a reasonable straw-man proposal.
