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
