California took the top spot among states implementing energy-efficiency measures, according to a report released Wednesday.

Judged on six policy areas, California led Massachusetts, Connecticut and Oregon in the American Council for an Energy-Efficient Economy's 2009 State Energy Efficiency Scorecard. Washington placed seventh in the 50-state rankings.

The group scores states on their efforts in six policy categories: utility and public benefits programs, transportation policies, building energy codes, combined heat and power, state government initiatives and appliance energy efficiency standards.
