The forward-looking energy picture in the Twin Cities is complex: while it includes the glamor Greenery-- energy from wind, waves, and other renewables--it's also about retrofitting buildings for energy efficiency and lower cost, conserving energy in small but telling ways in corporate and home settings, and continuing to develop energy sources that are cleaner, if not officially Green, like natural gas; and innovations to make our old energy standbys like petroleum more efficient and user-friendly.
