May the road rise up to meet ya, but not so fast as to hit your nose!
Getting hit in the nose is one of the main concerns with energy these days.
It's interesting to see how Santa Clara moved in the 1970s and 80s to avoid that - and is now reaping the benefits. The city bought land - a larger acreage than the city itself - for renewable energy.
"It's become popular, hasn't it?" said Don Von Raesfeld, Santa Clara's city manager at the time, chuckling about the city's unusual buying spree. By planning a chain of wind, water and steam plants on land that otherwise would go undeveloped, the city hoped to protect customers of its hometown power company from massive rate hikes.

Santa Clara's increasingly wise looking investments includes both wind and geothermal energy. Wind is now cost competitive with fossil fuel energy. It has faced however 2 major criticisms. One is often local opposition due to wildlife concerns (valid in the case of older turbines on Altamont pass but now wholly addressed by newer larger turbines which turn slowly and better siting). The second issue has been "baseload" - the electricity isn't necessarily generated when you most need it.
However, solutions in these areas are being offered. Scientific American recently covered energy storage in it's excellent January 2008 article on solar.
Compressed-air energy storage has emerged as a successful alternative. Electricity from photovoltaic plants compresses air and pumps it into vacant underground caverns, abandoned mines, aquifers and depleted natural gas wells. The pressurized air is released on demand to turn a turbine that generates electricity, aided by burning small amounts of natural gas. Compressed-air energy storage plants have been operating reliably in Huntorf, Germany, since 1978 and in McIntosh, Ala., since 1991. The turbines burn only 40 percent of the natural gas they would if they were fueled by natural gas alone, and better heat recovery technology would lower that figure to 30 percent.
Studies by the Electric Power Research Institute in Palo Alto, Calif., indicate that the cost of compressed-air energy storage today is about half that of lead-acid batteries.
And smarter grids are another:
So for 2008, perhaps the old Irish blessing should be: May the road rise up to meet you. May the wind be always on your turbines. May the sun shine warm upon your solar cells!
