Yes, saving energy is cheaper than making energy.

Utilities have options when it comes to meeting customer demand for electricity. They can build power plants to convert fossil fuels to energy. They can capture renewable resources like solar and wind. And they can work with residents and businesses to lower demand by implementing energy efficiency programs.

Electricity savings keep rising, year after year

Electric utilities and independent statewide program administrators deliver a substantial share of efficiency programs across the country. Some utilities have delivered such programs for decades. Since the mid-2000s, though, the size and scope of the programs have grown dramatically. Today, utilities and administrators implement energy efficiency programs in all 50 states and the District of Columbia.

Want to weigh your state’s Clean Power Plan compliance options? Check out our new SUPR 2 calculator

In October 2015, the Environmental Protection Agency (EPA) published its Clean Power Plan (CPP) final rule, regulating greenhouse gas emissions from existing power plants. Now that the final rule has been released, policymakers, state governments, utility and power plant owners, and other stakeholders are weighing their options to reduce carbon dioxide (CO2) from the power sector for compliance with the rule.

The amazing drop in home appliance energy use

Appliance efficiency has increased remarkably over the past several decades. The graph below tracks the energy efficiency of four household appliances over a 35-year period. Three of the products (clothes washers, central air conditioners, and refrigerators), show a 50% or greater reduction in energy use over that period, and the fourth product, gas furnaces, shows a smaller but still significant reduction of 18%.

2015 goes out with a burst of new efficiency standards: 2016 promises more action

The final few weeks of 2015 proved busy ones for new national appliance and equipment standards. The Department of Energy (DOE) completed the biggest energy-saving standard in agency history, along with several important but lower-profile standards which will collectively yield large energy and economic savings. Some of them point the way to much larger future savings.

Cars got quicker, more powerful by weight, and more fuel efficient in the last 40 years.

Over the past 40 years, light-duty vehicles in the United States have achieved remarkable gains in both fuel economy and performance. The graph below shows average miles per gallon, power-to-weight ratio, and 0-to-60 acceleration time of new cars and light trucks since the late 1970s. Fuel economy improved dramatically from 1975 to 1987, driven by the original Corporate Average Fuel Economy (CAFE) standards, which were adopted in 1975 in response to the 1973 oil embargo by Arab states.
