While reading this story about changes in the water rights laws of western states, [h/t Instapundit] this bit at the end caught my eye.
Ms. Fitzgerald, an associate professor of sociology at Fort Lewis College in Durango, still lives the unwired life with her own family now, growing most of her own food and drinking and bathing in filtered rainwater.
Rain dependency has its ups and downs, Ms. Fitzgerald said. Her home is also completely solar-powered, which means that the pumps to push water from the rain tanks are solar-powered, too. A cloudy, rainy spring this year was good for tanks, bad for pumps.
*Sigh* Somebody actually designed a solar powered system to pump water out of a rain filled system. Somebody voted for Obama.
The entire point of energy systems is to shift work in time and space to when and where we need it. Weather-dependent energy sources can’t shift work in time and space. Instead, the work happens when and where the weather wants it to happen. Weather-dependent energy systems cannot perform this most basic task of shifting work and that is why they are worthless for any large-scale use.
I mean, if weather-dependent power can’t meet the needs of a hippy college professor, why do people think we can run factories, transportation and hospitals with it?
[By the way, the water rights laws of the American West might seem bizarre but they do make sense in the context of the region's historical development.]
