Increase solar power 700-fold to displace coal

• Vastly increase PV and solar thermal technology
  use
• 120,000 TW available, .02 of that needed to
  replace coal nuclear
• Pros
• Very scalable
• No C02 emission during operation
• Ability to integrate easily
• Relatively unlimited supply of resource materials
• Cons
• .1 to 70 component of national power supply
• Efficiency of current technology
• Balance material production with device production

3
Increase fuel economy of two billion cars from
30-60 mpg

• More efficient engines and increased
  hybrid/electric technology
• 60 mpg cars already exist
• Pros
• Reconstructing auto industry
• Increases ability to compete with foreign auto
  makers
• Cons
• Still depends on oil industry

4
Cut electricity use in homes, offices, and stores
by 25

• Improve building practices, and enforce more
  efficient appliance use
• Buildings account for 40 of energy use in the
  US, leading to a 10 overall cut in electricity
• Pros
• Reduce peak load, reducing need for backup power
• Saves money over time with reduced utility costs
• Cons
• Need to retrofit current buildings
• Higher capital cost

5
Smart Transportation

• 1 billion cars have 5000 miles/yr driven, ½
  billion 10000 miles/yr , ½ billion off the road
• By preventing 500 million cars from entering the
  market, and more people to drive less, much less
  CO2
• Pros
• Technology already exists
• Stimulate market in new personal transportation
  technology
• Public transportation creates jobs
• Promotes healthier cities
• Cons
• Difficult to dictate the market, especially in
  non industrialized countries
• Promoting societal shift from driving to using
  alternative transportation methods
