An Issued Challenge
Goal: Provide resources for a global population that will quadruple in 100 years
Done: 1900 – 2000 Consequences: Depends on your point
of view about progress versus quality of life versus human condition

Business As Usual ScenarioBusiness As Usual Scenario
Population stabilizes to 10-12 billion Population stabilizes to 10-12 billion by the year 2100 (possible to do)by the year 2100 (possible to do)
Total world energy use from 2000 to Total world energy use from 2000 to 2100 is 4000 Terra Watt Years 2100 is 4000 Terra Watt Years (Current US use is about 1.5 TW (Current US use is about 1.5 TW years)years)

Coal Remains a Real ProblemCoal Remains a Real Problem
• 51% of all electricity in the US is coal-fired and coal production in the US is up
• China is currently adding 1 new 1000 MW coal fired steam plant every 10 days to its energy infrastructure.
• Coal production in India is also significantly up.
China Could be the Tipping PointChina Could be the Tipping Point
• Increased Methane emissions from rice cultivation
• Chinese private vehicle fleet is doubling every 3 years.
• Coal fired electricity to increase
• Combined effects – China will equal the US in greenhouse gas emission per year by the year 2015-2017.
