Speaker: Amory Lovins, Founder and CEO, Rocky Mountain Institute, Snowmass. By the 2040s, the United States can eliminate its use of oil and revitalize its economy, led by business for profit. Existing technologies can redouble the efficiency of using oil (including tripling the efficiency of uncompromised cars, trucks, and planes) at an average cost of $12/bbl, and can replace remaining oil use with advanced biofuels and saved natural gas. These innovations don't require fuel taxes, subsidies, mandates, or new Federal laws, but can be driven by competitive strategy for the car, truck, plane, and fuel industry and by military requirements.
