"t is a crucial, if geekish, point: Wind and solar power are NOT intermittent, they are VARIABLE. If someone talks about problems with the intermittencies of wind and solar energies, it is out of ignorance or to intentionally discredit them. Obviously, the sun does not always shine and the wind does not always blow but those things can be scheduled and forecasted and are no reasons whatsoever not to keep building wind power and solar energy as fast as is humanly possible. The Western Wind and Solar Integration Study, from the National Renewable Energy Laboratory (NREL) of the U.S. Department of Energy (DOE), says transmission system tools are now available that would allow the Mountain West and Southwestern states to get 35% of their electricity from wind and solar energies by 2017. All it will require, aside from the building of the wind and solar production capacity, is a change in the WestConnect group of grid operators' standard operating procedures."

Recently, researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) announced that they have moved closer to creating a thin-film solar cell that can compete with the efficiency of the more common silicon-based solar cell. The Copper Indium Gallium Diselenide (CIGS) thin-film solar cell recently reached 19.9% efficiency in testing at the lab, setting a new world record, according to NREL.

**Extremely useful comparison + charts** Covers 11 technologies from 6 data sources. Source detail included in appendix. Costs: capital, fixed, operating, learning factor; Technical: size, heat rate, [potential] capacity factor, service life. Note on unit life: not all data sets include this, some run as long as plant is economic (no pre-determined retirement age), can represent max service life or is just used to compute economics (e.g. LCOE).

Last week, the Japanese newspaper Nikkei caused a buzz by reporting that a redesigned Toyota Prius, to be released next year, will come equipped with solar panels. Toyota spokespeople will neither confirm nor deny the report, but several companies already offer solar roof kits for the Prius, and researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), in Golden, CO, have been testing one on a Prius modified to plug into the electrical grid.

According to the NREL report referenced above, converting biomass into cellulosic ethanol can be done at about a 45% efficiency (i.e. 45% of the energy of the biomass makes it into the fuel.) In contrast, biomass can be converted at 33-37% efficiency [pdf] when cofired. Combining this with the 5x improvement of drivetrain efficiency that comes with electric propulsion, and the same amount of biomass converted to what I'll call "cellulosic electricity" will take a vehicle 3.8x as far as it would in the form of cellulosic ethanol.
