Wind Turbines along San Gorgonio Pass, Interstate 10, Palm Springs, CA

• Works profitably in very windy locations.

• Large and unsightly.

• Requires lots of land.

• Works well in windy deserts where few people live. Texas has huge potential.

Diablo Canyon Nuclear Plant, Central Coast

• Uranium is a limited, non-renewable resource.

• Nuclear power is inherently dangerous.

• Targets for terrorism.

• Earthquake risks.

• Inevitable radioactive waste.

Hydroelectric Hydroelectric

Shasta Dam, Lake Shasta, Mt. Shasta

• Clean, renewable energy

• Little growth since nearly all rivers in the MDCs damned.

• Globally dams are still being constructed agressively.

• China currently building Three Gorges, the largest dam ever.
