Average American releases 5 tons of carbon per year into the atmosphere. Average Indian: 1/4 ton
•Natural gas supplies the US with 26% of its energy, 18% for the UK, 4% for India and 3% for Japan
•Oil supplies the US with 30% of its energy, 50% for the UK, 10% for Japan, 22% for India and 90% for Nigeria
•The former Soviet Union is the largest oil (nearly 12 million barrels per day) and gas producer (25,000 billion cubic feet per year)

Renewable: Geothermal Renewable: Geothermal
The Geyers, Santa Rosa, CAWorld’s Largest Geothermal Plant
Renewable: WindRenewable: Wind
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.
Renewable: SolarRenewable: Solar
• Passive Solar
• Active Solar - Photovoltaics
• Initially expensive
• Interconnectivity and grid issues
• Huge Untapped Potential
• Federal and State Government incentives come and go.
Non-renewable: Non-renewable: Nuclear Nuclear
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.
