From Carol G. Q: I've got a plug-in hybrid vehicle. How do I know what the best hours are for charging? (it takes 12 hours at home) A: (Mike Winka) Overnight is best time (environmentally) to use electricity. Reason: nuclear provides most of the electricity at night & there are no CO2 emissions from nuclear. However, if signed up with the utility "time of day" electrical service, then charge during hours with the lowest priced electricity From Anshul G: Would like to get references for ground-source heat pump installers in Bergen County if anyone can share that info. A: (Mike Winka): I do not but this is the trade org for geothermal https://geoexchange.org/ and they may have a list of installers in NJ. From John W: Stockton University has geothermal From Peggy M: I've heard a lot about Stockton's geothermal system. From Michael Winka:Stockton's large geo is a thermal storage system although they have individual geothermal in some buildings From Ken D: Sue, how do you when the electric resistance heat was on? Is there any indicator on your system? A: no firm answer because the electrical aux heater is quiet; however, widening the thermostat dead band from 2 degrees to 4 degrees will likely lower the time the auxiliary heater is operating. ALSO, turning "OFF" the electric heater at the furnace, or opening the breaker will prevent the electric heater from operating. A:From John W. My installer put a simple toggle switch on the thermostat lead that triggers the emergency heat so it is disabled till you flip the switch From Marty L: Sue, this is great. You are certainly walking your talk. How do the different CO2 removal options compare cost wise? From Sue Dorward: (discussed in recording) Carbon Removal Challenge: global university team: most innovative, scalable/practical carbon removal.

DONATE HERE: https://fundrazr.com/carbonremovalchallenge From Enis B: Would a passive house lower your electric bills from what they are now? A: (Steve Miller) YES! electric bills would be quite low. A passive house is highly insulated and sealed. Subsequently, it has minimal heat loss in winter or minimal heat gain in summer. Because the house is tightly sealed, an air exchanger (requiring electricity) must be present to circulate fresh air., but the heat pump (normally the greatest electrical load) will be operating at lower speed and lower electric bill. From Steve Miller to Everyone: Sue, you referred to your cold climate heat pump was "undersized" what was the impact, if any? A: from Jim Price (HEAT PUMP CONTRACTOR): Just so everyone knows Sue's heat pump is only slightly undersized for 2% of the run time. Maximum Capacity is 48,000 BTU/hour. House Load for 2 weeks in winter will require 53,000 BTU/hour. From Gail A: Do you know best practices for opening and closing your windows in comfortable weather with mini splits? A: Steve Miller: Keep off the mini-split, and open your windows as you wish. The disadvantage of turning off the mini-split is the loss of summertime dehumification normally supplied by the mini-split, or dehumidification supplied by any heat pump or AC. From Jim P. How do I calculate my Flight CO2 consumption? A: (Steve): Eleven Airlines That Offer Carbon Offset: https://www.conserve-energy-future.com/airlines-that-offer-carbon-offset-programs.php From Enis B How can you be sure they are not selling the same biochar to several people? A: in recording 19:58:54 From Ken D Sue, are you a solar consultant who can help someone with very little knowledge select the right solution for their house? A: in recording, Also see details about solar in Mike Winka's "Solar 101" presentation on 2024-12-19 found in https://climate.smiller.org/50x30/building-electrification/All-heat-pump-webinars.html From Nadine S. : How can one connect with an Electrification Coach in NJ? IF YOU WANT HELP FROM A TRAINED ELECTRIFICATION COACH (free of charge), follow this link: https://tinyurl.com/yc2ew6rc Also see the last slide at the end of the recording 20:09:02 From Poornima Gupta to Everyone: Thank you Sue, this was great! 20:11:48 From Ken Dolsky to Everyone: For what it is worth, i think it is much more effective to spend money on moving to fossil free energy systems than buying carbon offsets. Which is paying to solve the problem we are allowing to persist. 20:13:14 From Jim Price to Everyone: Comfortable Homes jim@comfortablehomes.com 908-642-8394 20:13:52 From Nadine Sapirman to Everyone: Thank you!!! 20:14:04 From Gail Arnold to Everyone: Thank you! 20:14:07 From Sue Dorward to Everyone: Thank you, Steve and Pat! 20:15:20 From Edward Neblock to Everyone: Thank you! 20:15:26 From Carol Gyzander to Everyone: Thanks - great info!
