Solar and wind power on every roof - should urban rooftops be used to power cities?

Smart water meters - Can we encourage sustainable behavior through providing more information on the resource we consume?

Ideas 6-10

Reward sustainability with tax credits - money talks. Might you be more willing to lead a sustainable lifestyle if it paid well?

Appoint a sustainability champion - would a leader in sustainability be able to inspire people to live more sustainable lives?

Ban dishwashers - Dishwashers provoke a lively debate among environmentalists. Should they be banned?

Store energy efficiently - we have plenty of sustainable energy options, but it’s hard to generate on demand. But if we improve battery technology, could sustainable energy alternatives become more popular. 

City Lab - How about we build a new city specifically to experiment with sustainable urban alternatives?
