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
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
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
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
