We focus all our efforts on supply-side solutions (renewable energies, electric-powered vehicles, energy-efficient appliances), but have failed to acknowledge the root of our environmental problems...over consumption. Demand-side tactics are deemed anti-capitalistic, un-American. So rather than turning off the lights when we don't need them, we install fancy solar-panels on our roofs, and rather than catching a ride-share, we buy the hybrid Highlander.
