California Drought: Renewable Powered Pumps to the Rescue?
Governor Schwarzenegger has declared a drought in California following one of the driest springs on record. This of course is bad news to the farmers in the state and those of us in the East Bay who want grass for a yard and not a dustbowl.
The majority of the state's water comes from the Sierra snowpack and that pack is thinner this year than in normal years. Some farmers can make up the difference with deep water pumps, but those pumps run on diesel and use 5 gallons per hour, meaning one hour of pumping costs about $26-$30 per hour depending on the cost of fuel.
Conservationists and environmentalists point to global warming as the driver of snowpack reduction, whereas global warming naysayers call the drought cyclical. Regardless of who is right and given the cost of fuel right now, it leads to interesting questions about markets you don't hear much about.
The first market is desalination. This is a technology that has never made sense because of the fuel needed--wood, coal, natural gas--to power a desalination plant. Today, solar and wind, and (longer term) maybe even tidal resources could power such plants and give coastal states (hello drought-stricken Georgia) an almost inexhaustable source of fresh water. Not to mention it would help us deal with rising sea levels (sorry, bad joke).
The other area where renewables could help is deep water pumps. A lot of areas around the country have deep water reservoirs that are expensive to tap and require fuel to harvest. Using wind and solar power would dramatically cut costs for farmers and reduce the strain on reservoirs, rivers and other irrigation options.
If you are marketers in the aforementioned areas, this is a prime time to educate the market and government regulators about the viability of such technologies to generate sales leads and stimulate new investment. It will be interesting to see if either of these areas get any interest at the IDG GreenXchange event or Solar Power 2008. By then, California will be five months into an official drought and no doubt there will be plenty of discussion about the role renewables can play in water shortages.
