Scheme 1 (25%): Large scale use of renewable energy sources: solar panels cover the desert floors, or wind turbine lining the seashores etc.
Scheme 2 (18%): Enforce all the mentioned schemes by law.
Scheme 3 (16%): Let things go on as it is now for another 10 years but invest heavily on future technologies like fusion power, lightweight high efficiency solar panels etc.
Scheme 4 (14%): Stone age ways of life rocks!
Scheme 5 (13%): Mandatory installation of solar panel and wind turbine on top of every house that feeds any excess energy generated into the grid.
Scheme 6 (7%): Only allow to build all-electric or hybrids for any future car models.
Scheme 7 (6%): What's wrong with oil? We are already totally dependent on oil. Any drastic step to reduce dependency of oil is unworkable.
Scheme 8 (2%): Enforce nation-wide drastic energy saving schemes: switch off all building lights, including private homes after certain time, leaving only a few essential street lights.
