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
