Mobile homes move toward efficiency

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.

US electricity use is no longer growing

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%.

Sharing the human face of energy efficiency

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.
