An updated ACEEE analysis, prepared with assistance from Energy and Environmental Analysis, Inc., shows that energy efficiency, both alone and combined with renewable energy, can reduce natural gas prices and price volatility. Deploying cost-effective, aggressive efficiency programs over the critical next few years (e.g., 4.7% electricity savings and 4.1% gas savings over five years) would cut wholesale gas prices as much at 25%, or about $1.50 per MCF. Since new gas supply options will take several years to bring on line, efficiency investments are the best available tool for balancing gas markets for the near future. By reducing demands for electricity and natural gas, especially during peak periods, and increasing the share of renewable energy we can:
What Does this Mean for Consumers?
Residential consumers are now experiencing the full impact of price increases in their gas bills, which have increased an estimated 42% since 1999, increasing consumers' gas expenditures by almost $15 billion. Energy efficiency investments could reduce next year's bills by over 11%, reducing residential gas expenditures by almost $6.5 billion nationally, saving the average residential natural gas consumer almost $110. These savings will continue for the next five years, averaging $136 per year per residential natural gas customer. It is worth noting that changes in just one state or region can result in price reductions in the immediate region as well as the nation as a whole. These energy efficiency investments are highly cost effective, with a benefit cost ratio of 6.36.
At a national level, additional savings can be achieved from reductions in electricity consumption by end-users. Natural gas consumption in the electric power sector is reduced by about 4 % over the next five years with expenditures reduced by $9.6 billion in 2006, and by over $ 56 billion cumulatively by 2010.
To achieve these reductions would require an investment of slightly over $22 billion dollars over five years. As Figure 2 shows, the investment is weighted disproportionately toward electric efficiency investments, while the benefits disproportionately occur in end-use natural gas expenditures, in large part because of the dramatic natural gas price reduction that result from reductions in demand.
Policy Solutions
Policymakers at the state and federal level can take a number of concrete actions to realize the benefits that result from expanded energy efficiency and renewable energy resources. No single policy strategy will achieve the results outlined in this analysis. Rather, a portfolio of strategies is needed to achieve quick and sustained savings from energy efficiency and renewable energy resources. These strategies include:
For utility regulators, it is important that they:
