What role, if any, can renewable energy play in CO2 reduction?
• Renewable energy plays a small role now, but it is expected to play an increasingly important role over time. Wind and biomass energy are already cost-competitive with other forms of electric generation in some instances. Great technological strides have been made recently in hydrogen-powered fuel cells. There is enormous potential for solar energy and hydrogen to power our homes and cars in the future. • Several states have adopted renewable portfolio standards that require an increasing role for renewables as sources of electric power. Because transportation accounts for a significant of greenhouse gas emissions internationally, how do you propose we reduce emissions in this sector? What do you think the technologies of the future may be? • Some technologies that will reduce emissions are already here, such as hybrid-electric vehicles like the Toyota Prius. • There have been exciting breakthroughs in hydrogen-powered fuel cells. Both fuel cells and biofuels are potential options fo
