2. 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
