The Race to a Renewable Future Who is Going to Get There First? Terry Penney, Technology Manager NREL’s FreedomCAR & Vehicle Technologies Program November 11, 2005
Transportation and Energy Challenges • Increasing demand for a finite resource - petroleum • Emission reductions and fuel-economy gains have been offset by: • More people • More cars • More vehicle miles traveled • More pollution • Decreasing fuel economy

A Next Step: Plug-in Vehicles PHEV A Plug-in Hybrid Electric Vehicle (PHEV) uses today’s hybrid technology, adding a bigger battery and the capability to plug into your garage (or elsewhere) to fuel the battery with electricity. At 3 cents/mile to fill up an electric vehicle, compared to about 11 cents/mile to fill up a gasoline vehicle today, why not make a shift?

Zero Energy Building:Breaking out the Savings Energy Bottom Line During the month of June 1998, the occupied Zero Energy Home in Florida, consumed only 335 kWh of utility-grid power for all its electrical needs. This compares to 1,839 kWh used by the unoccupied control home for air-conditioning only! The monthly power cost in the Zero Energy home was only 18% of the control home’s power cost.
A Renewable Community Vision A state-of-the-art, master planned community using advanced technologies and strategies to: • Maximize sustainability, economic benefits, quality of life • Minimize environmental impacts • Integrate currently disconnected systems (e.g., transportation and building energy systems) • Establish a viable community today while leading the transition to the communities of tomorrow • Develop technologies and approaches applicable to communities worldwide The community will have aggressive goals using sound strategic business and economic principles, with a short and long term focuses.
10 Critical Elements of a Renewable Community • Community generates its own energy supply • Design and decisions based on sound business principles • Cost of living in the community is optimized for consumer • Energy conservation features are core • Vehicle miles traveled are substantially reduced • Encourages shared resources to minimize consumption • Pollution is minimal or non-existent • Integrate workplace with living place • Master planned community as an integrated system • Magnet for economic development • A community that people will demand to live in!
Barriers/Challenges • Technology • High value, low cost • Reliable • Accessible • Clean • Markets • Sustainable • Accessible • Competitive • Policies • Stable • Consistent • Long-term

Selecting Partnerships With • Auto Manufacturers • Builders • Developers (Land use, water, infrastructure) • Utility Companies • Other Suppliers • City, County, State, Federal Government and Non-Government Entities • Others?
Paving a Way (examples) • DestiNY Renewable MegaMall: Syracuse, New York • BioTown USA: Indiana • Sarasota, Florida: Resolution to advance plug-inhybrids and renewables • Austin, Texas: Resolution to advance plug-in hybrids and renewables • Plug-in Hybrid Prototypes by: Mercedes, DaimlerChrysler, Toyota (potential), and others • Energy Smart Buildings: Japan, San Diego, Sacramento, Austin, Chicago, etc.
