Last summer I saw a presentation on “deep decarbonization” that outlined necessary changes in the U.S. economy in order to sharply reduce greenhouse gas emissions. The presentation was fascinating, offering some very specific elements to focus our attention. For example, the following graphic shows the average number of replacements for various infrastructure types prior to the typical deadline of 2050. A hot water heater might be swapped three times by 2050, providing several opportunities to make it more efficient or switch its fuel source.
