Can the US cut its energy use in half by 2050? Yes, but we will have to double down on our efforts.

Five years ago, ACEEE found that energy efficiency could reduce projected 2050 US energy use by 40–60%. As a result, ACEEE established a strategic goal to reduce projected 2050 energy use by 50%. We thought it was time to check on our progress and ask whether our goal still seems reasonable. We find that energy use has been stable in recent years, reversing historical growth, a very positive development that is due in significant part to increasing our energy efficiency.

Making sense of commercial-sector energy use data

Commercial-sector energy use in the US increased by 63% from 1979 to 2012, rising from total source energy use of 10.6 quads in 1979 to a peak of 18.4 quads in 2008 before declining to 17.4 quads in 2012.  This growth can largely be attributed to a corresponding increase in commercial building floor area, which grew by 70% over the same period. But that is only part of the story. As the graph below illustrates, as floor area has trended upward over time, energy use per square foot has gone up and down, peaking in the 1999-2003 period but declining since then.

Why we need innovations AND insulation

Bill Gates, billionaire philanthropist and co-founder of Microsoft, marked several items off his 2015 to-do list when he announced the creation of two coalitions (one of international governments, the other of billionaire investors) for investing money in developing renewable energy innovations, while pledging one billion dollars of his own money to the effort.

First-ever pump efficiency standards reflect industry and advocate consensus

The Department of Energy (DOE) issued new efficiency standards today for commercial and industrial pumps that are based on efficiency levels negotiated by manufacturers, efficiency advocates, and other stakeholders. In addition to establishing the first-ever national efficiency standards for pumps, the final rule also provides a mechanism for energy efficiency programs to incentivize high-efficiency pump packages.

Multiple benefits prove energy efficiency is a gift that keeps giving

Energy efficiency improvements provide value over and above utility bill savings. ACEEE’s new report Recognizing the Value of Energy Efficiency’s Multiple Benefits describes the gains outside of energy savings created by energy efficiency improvements. Many of these benefits accrue to residential and business energy consumers. Additional benefits accrue in the form of cost reductions to the utility system, resulting in lower costs for all customers.

How does your country rank for energy efficiency?

Evaluating how countries use energy provides valuable information necessary to identify energy waste, improve energy systems, and promote smarter economic growth. An efficient economy is one that minimizes its energy needs while providing better access to goods and services.

For the past 35 years at ACEEE, we’ve informed policymakers and the public to advance energy efficiency in the United States through in -depth technical and policy analysis.
