A sweeping climate bill introduced in the US House of Representatives this week includes billions in microgrid funding. By ParabolStudio/Shutterstock.com The CLEAN Future Act authorizes $565 billion in spending to cut greenhouse gas emissions to net zero by 2050, with an interim target of reducing carbon pollution by 50% from 2005 levels by the end of this decade. The bill, H.R. 1512, introduced March 2, requires utilities to sell increasing amounts of carbon-free electricity until the power sector is fossil-fuel free by 2035. This is in line with a goal set by President Joe Biden. The legislation builds on a draft bill House Democrats released in January 2020.
