The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
In the United States, in everyday usage the SEER is the more common measure of energy efficiency for cooling devices, as well as for heat pumps when in their heating mode. For energy-conversion heating devices their peak steady-state thermal efficiency is often stated, e.g., 'this furnace is 90% efficient', but a more detailed measure of ...
The California Energy Commission is the primary energy policy and planning agency. As of 2017, California is a deregulated electricity market. [ 63 ] It has a number of electric load-serving entities , including as of 2015 six investor-owned utilities (IOU), 46 publicly owned utilities, 4 electric cooperatives, 3 community choice aggregators ...
These furnaces were still big and bulky compared to modern furnaces, and had heavy-steel exteriors with bolt-on removable panels. Energy efficiency would range anywhere from just over 50% to upward of 65% AFUE. This style furnace still used large, masonry or brick chimneys for flues and was eventually designed to accommodate air-conditioning ...

California is the state with the largest population and the largest economy in the United States. However, it is second in energy consumption, after Texas. As of 2018, per capita consumption was the fourth-lowest in the United States, partially because of the mild climate and energy efficiency programs.
The increases were driven by several factors, including consumers with more money to spend, thanks partly to stimulus cash, as well as supply chain disruptions and higher energy prices. A Berkeley ...
CMS Energy's primary subsidiary, Consumers Energy, announced Michigan's first nuclear power plant in 1961, Big Rock Point in Charlevoix, Michigan. [ 15 ] [ 16 ] The company announced another nuclear plant, Palisades Nuclear Generating Station on Lake Michigan, [ 17 ] [ 18 ] which first produced electricity in December, 1971 to serve 400,000 ...
