4. California Electricity
California Energy Commission, 1999

5. Fossil Fuels Coal - most polluting; L.D.C.s
Oil - used extensively in all countries, with the developed world consuming the most
Natural Gas - cleanest of the fossils fuels; developed countries
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)

6. Fossil Fuels: How much is left?
Proven Reserves vs. Potential Reserves
Much thought to lie under South China Sea and in NW China
Oil: at current rates of consumption, petroleum gone in < 40 years. Rate of discovery is lower than increasing rate of consumption.
Natural Gas: 80 years; much less if we switch from oil to gas.
Coal: hundreds of years.

15. Energy Production

21. California Geothermal (<5%)
The Geyers, Santa Rosa, CA World’s Largest Geothermal Plant

22. California Wind (1%) 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.
Wind Turbines along San Gorgonio Pass, Interstate 10, Palm Springs, CA

23. California Solar (<1%)
Initially expensive
Interconnectivity and grid issues
Huge Untapped Potential
Federal and State Government incentives come and go.

24. California Nuclear (16%)
Uranium is a limited, non-renewable resource.
Nuclear power is inherently dangerous.
Targets for terrorism.
Earthquake risks.
Inevitable radioactive waste.
Diablo Canyon Nuclear Plant, Central Coast

25. California Hydroelectric (24%)
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.
Shasta Dam, Lake Shasta, Mt. Shasta

26. Global Atmospheric Issues
The Ozone Hole
Global Warming

27. The Greenhouse Effect
A normal climatic warming effect caused by permitting incoming solar radiation but inhibiting outgoing terrestrial radiation.
Three gases are the primary cause:
Carbon Dioxide (CO2)
Methane (CH4)
Water Vapor (H2O)

28. Global Warming

29. The Global Warming Hypothesis
Human-induced rise in CO2 levels is theorized to lead to unnatural warming of atmosphere.
Likely effects:
Increased storminess
Rising sea level (.2-1 meter in 100 years – IPCC, 2001)
Loss of arable land (some areas hotter, others cooler)
Extinction of thousands of species
Loss of nearly all coral reef
Possible effects even include climate “flip-flop” wherein dangerous rapid cooling sets in!
