TRANSCRIPT
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
