In Future Drive, Daniel Sperling addresses the adverse energy and environmental consequences of increased travel, and analyzes current initiatives to suggest strategies for creating a more environmentally benign system of transportation. Groundbreaking proposals are constructed around the idea of electric propulsion as the key to a sustainable transportation and energy system. Other essential elements include the ideas that:

• improving technology holds more promise than large-scale behavior modification
• technology initiatives must be matched with regulatory and policy initiatives
• government intervention should be flexible and incentive-based, but should also embrace selective technology-forcing measures
• more diversity and experimentation is needed with regard to vehicles and energy technologies
