On October 13, 2010, the American Council for an Energy-Efficient Economy (ACEEE) released its fourth annual State Energy Efficiency Scorecard report, which ranks all 50 states and the District of Columbia according to their overall energy efficiency.
Among the major state advances highlighted in the scorecard are:
- a near-doubling of state energy efficiency budgets from 2007 spending levels;
- the adoption or active consideration by more than half the states of Energy Efficiency Resource Standards that establish long-term, fixed efficiency savings targets;
- a one-year doubling of the number of states that have either adopted or have made significant progress toward adopting the latest energy-saving building codes for homes and commercial properties.
California leads the nation in its level of investment in energy efficiency across all sectors of its economy; other states in the top 10 include Massachusetts, Oregon, New York, Vermont, Washington, Rhode Island, Connecticut, Minnesota, and Maine. The four states that showed the most improvement in their rankings in 2010 are Utah, Arizona, New Mexico, and Alaska.
