Can efficiency improvements achieved in past decades be sustained in the future? How much impact does the rebound effect have on energy efficiency potential out to 2030, or even 2050?
Do you know which government in the United States is the biggest laggard on energy codes for homes? The federal government. But that’s about to change.
Manufactured homes and the “HUD Code”
Although building codes are mostly set by states, the federal government sets codes for manufactured homes (sometimes called mobile homes) because the factory does not always know where a home will end up. Manufacturers shipped 70,519 homes in 2015, more than the number of single-family homes built in any state except Texas.

The 2016 International Scorecard is almost here. Tune in next week to see the Olympics of energy efficiency
As world-class athletes descend on Rio for the 2016 Olympic Games, twenty-three countries are vying in a very different arena to become leaders in energy efficiency.
Ever wondered just how much energy we consume to power our economy? To keep our buildings working, machines humming, and wheels running? Are we really energy smart as a country?
For many years, electricity use in the United States increased steadily, in lock-step with growth in the economy as measured by Gross Domestic Product (GDP). But since 2010, electricity consumption has been essentially flat, even as GDP has risen steadily. The earlier trend and the divergence are shown in the graph below. New figures just released by the Energy Information Administration (EIA) show that electricity use in 2015 was nearly identical to use in 2010, even as the economy grew 11%.
As energy efficiency geeks, we here at ACEEE are deep into the numbers, publishing report after report on the quads and TWh and MMT CO2 savings from efficiency. We know these numbers and units represent major benefits for the nation, but sometimes we find it hard to explain—to policymakers, advocates outside of the energy world, and even our own families—what they mean for individual American families. We’re trying to change that.
The past year included many successes, including quite a few that we can build on in the new year. Among the notable developments in 2015:
Standards the result of negotiations among broad group of stakeholders
Washington, DC—Energy efficiency standards issued today for rooftop air conditioners and heat pumps—which represent the largest energy and pollution savings of any rule ever issued by the Department of Energy—will benefit businesses, manufacturers, and the environment, according to four of the organizations that participated in the negotiations leading to the announcement.
