Some carbon capture technologies have a much higher energy penalty than others. (c2es.org)
But the increased energy requirements of carbon capture and sequestration (CCS) mean more mining to provide the 10 % to 40 % energy penalty created by the carbon capture and sequestration process. (sourcewatch.org)
In addition, use of the sealed «cathedralized» attic in hot climates can be a successful approach to avoiding pervasive problems associated with ducts located in attics and air leakage at the ceiling level, without energy penalty. (buildingscience.com)
