This is great. When we are talking to clients another consideration is the future GHG intensity of the grid based on current commitments of the state,city, or utility. Some have committed to carbon neutrality by 2050 or so, meaning that after the first 25-30 years of life, an all-electric buildings will have only minimal energy-related carbon emissions…and during the first 25-30 years it will decrease. Many other have 20, 30, or 50% reductions over the next few decades.
