25. Where CO2 emissions between electricity and natural gas are close, it probably means the cost of reduction is high in $/ton.

One interesting question is "When does winter peak exceed summer peak if geothermal heat pump market penetration increases to 100%?" It happens twice. GHP will lower summer peak. So, you need to address not only actual summer peak but the original summer peak as well.pic.twitter.com/zJNoIvKZGX
Note: That graph assumes full fossil fuel heating in the winter and assumes all non-HVAC related consumption is unchanged. Thus, "starting winter peak" is 0kWh since there is no electricity consumption for winter heating.
