President Barack Obama is signing long-delayed legislation to boost energy efficiency in buildings.
Obama plans to sign the bill into law in the Oval Office Thursday afternoon. It aims to cut energy use in commercial buildings, manufacturing plants and homes.
The measure was widely popular in both parties. But it was defeated last year after becoming enmeshed in a partisan fight over the Keystone XL oil pipeline.
The bill exempts some energy-efficient water heaters from pending Energy Department rules. It also requires federal agencies to develop best practices to increase energy efficiency in federal buildings, among other provisions.
