General Motors hosted the Technology Solutions – Roadmap to Reinvention forum this week at the SAIC-GM Pavilion at the World Expo 2010 Shanghai. This is, in fact, the fifth instalment of GM’s ‘Drive to 2030’ Sustainable Urban Mobility Forum series. The forum discussed the range of urban challenges that will affect future transportation. Issues taken up included technological innovation, how to promote alternative energy sources, and the different roles and goal of sustainable urban mobility. The series has been addressing tomorrow’s transportation challenges and various solutions for overcoming them. Reliable Plant reports that petroleum continues to power about 96% of vehicles, with overall energy demand steadily increasing by about 2% a year. Daniel Hancock, GM vice president for strategic product alliances, pointed out that a single solution meeting all needs is not likely within the next 20 to 30 years.
