Our Generation’s Challenges The 21st century’s twin challenges are: • Global Warming (known and manifest) • Peak Oil (little known but imminent).
Global Warming Fires in Congo & Angola
Two Ways to Respond… • Germany, Japan, Sweden • Solar Energy • Hybrid Vehicles • Quit use of oil by 2020 • USA • Attack Iraq • Alaska National Wildlife Refuge (ANWR oil) • 25 x ‘25 … the rape of Soil and Ancient Water cloaked with environmental rhetoric
Which way will prevail? • “The American way of life is not negotiable.” [G H W Bush, 1992] • Check with the people of New Orleans for more details …. • Can we change course in time to avoid catastrophe?
Swenson’s Law To avoid deprivation resulting from the exhaustion of non-renewable resources, humanity must employ conservation and renewable resource substitutes sufficient to match depletion. www.OilCrisis.com/Swenson
Beating oil addiction with fraud • New Generation Vehicle (Clinton) • Hydrogen Highway (Schwarzenegger) • Cellulosic Ethanol (G W Bush)
Clean Coal? Pathological Disconnect

So what about Hydrogen? Am I missing something?! Energy Return on Energy Invested < ½
What do the “experts” say? “Active solar power ... works, though not nearly as well as fossil fuel… “Alternative energy sources ... are … implausible … without the subsidy of oil. The only remaining alternative is nuclear energy.” James Howard Kunstler www.HubbertPeak.com/nuclear

Internal Combustion … • Take 26.5 Quads of oil • Turn 21.2 into smoke • Use 5.3 to run things … How incredibly wasteful!?

Sustainable Transportation • Not cars • Not airplanes • Walking, Horses, Bikes, Sailboats … and Podcars
