{The host was John Hollins, who is here as Kimberlin John. Ed.] 13:19:52 From Dave Dougherty to Everyone: [pre-session notification] Expert Panel on Climate Change Adaptation and Resilience Results delivered its report in summer 2018 (and now appears to have been disbanded). https://www.canada.ca/en/environment-climate-change/news/2018/06/expert-panel-on-climate-change-adaptation-and-resilience-results-delivers-report.html 13:55:36 From Peter Bulkowski to Everyone: Alberta hours below -20 is for Calgary, but does not deal with Edmonton (or Red Deer or Medicine Hat)? [A brief search did not locate collated data for other cities in Alberta. One would have to downlaod extensive data sets and process them. Ed.] 14:04:20 From Peter Bulkowski to Everyone: Why doesn't nuclear energy (from the 700 MW Point Lepreau generating station) get the NB numbers down? 14:08:58 From Peter Bulkowski to Everyone: $120 billion to maintain capital of $8,000 billion is 1.5%. That barely keeps the buildings maintained (industrial is 2 to 4 %). 14:16:59 From Peter Bulkowski to Everyone: What is the cost of a '60s single family home deep retrofit? 14:17:30 From Charles Hall to Everyone: Have you included the energy cost of the new capital (digging up ground, pipes, or Carrier-type devices)? [It would seem Carrier-type devices refers to air-source heat pumps. Ed.] 14:17:55 From Charles Hall to Everyone: May be small, but should be included. 14:18:51 From Charles Hall to Everyone: Also, we need to think about Jevons' paradox. I am not complaining, good presentation. 14:19:26 From Hunter Lovins to Everyone: Jevons’ paradox has been shown to be, largely, a myth. 14:20:24 From John Meyer to Everyone: Question: It looks as though the heat pumps you are advocating are air source. With ground source heat pumps and geothermal storage (i.e., using solar hot water heat creation during the summer), the coefficient of performance (COP) could be 4 to 6 times higher than for air source heat pumps. 14:20:42 From Charles Hall to Everyone: Ahhhh, quite debatable, but not now. 14:29:21 From Charles Hall to Everyone: I remember in past that atmospheric heat pumps could not work below some temperature, a few degrees above freezing. Is that still true? How would you get to zero CO2 production if true? Resistance heating below a certain temperature or is question moot? [Modern ASHPs can work well to -20 degrees C, below which they lose efficiency. One can buy them with coil heaters for very cold conditions. Ed.] 14:32:54 From Hunter Lovins to Everyone: Another myth. 14:40:24 From Dave Dougherty to Everyone: Do you see any government taking on such a huge endeavour? It would be like trying to defeat the Axis Powers. 14:41:09 From Derek Paul to Everyone: I’d like your views on material availability for the retrofits and quality of workmanship. Can the necessary quality be assured? It’s so often crucial in retrofitting. 14:44:12 From Peter Bulkowski to Everyone: The decline in cost with a new product in assembly line production is not likely meaningful to retrofit buildings that are, to a considerable degree, unique. 14:44:52 From Ted Manning to Everyone: A comment: Governments must remove current barriers. The National Research Council (NRC) of Canada, along with provinces, is working to revise and coordinate building codes as a part of doing this. 14:48:18 From Hunter Lovins to Everyone: Brilliant, Ralph! 14:49:09 From jon legg to Everyone: My general question relates to how much could be gained by a serious attempt at interprovincial learning. 14:50:05 From Mike Nickerson to Everyone: I have a question about another possible pillar to a low-carbon energy system. 14:50:46 From Dave Dougherty to Everyone: Heating degree days (a measure of cold) do not look exceptionally high in much of Alberta. [This was is relation to the comment about Calgary vs Edmonton and Medicine Hat. From personal experience, having lived in Calgary for decades and visisted Medicine Hat many times, I would judge Medicine Hat as slightly warmer than Calgary. Ed.] https://climateatlas.ca/map/canada/hdd_2060_85#z=5&lat=51.24&lng=-100.81 [Comparisomns of climate for the two cities can be made with these links. Ed.] https://en.wikipedia.org/wiki/Medicine_Hat#Climate https://en.wikipedia.org/wiki/Calgary#Climate 14:54:30 From Jeff Passmore to Everyone: I have no idea what Charles is talking about. We need to be better communicators for Joe Blogs. 14:57:44 From Bill Pugsley to Everyone: Jevons’ paradox. https://en.wikipedia.org/wiki/Jevons_paradox 14:58:26 From Dave Dougherty to Everyone: Jevons paradox is so named because a program designed to reduce fuel use ends up increasing fuel use (by lowering the price of fuel). 14:58:50 From Jeff Passmore to Everyone: Ranchers in Alberta are not typically promoting, or in the pockets of, the Alberta oil and gas industry. In fact, they are frequently at loggerheads. 14:59:21 From Derek Paul to Everyone: Derek,the Jevons theorem is only valid in the traditional economy; not in a truly ecological economy. 15:00:33 From Jeff Passmore to Everyone: It does not necessarily lower the price, it lowers the total cost. 15:00:41 From Hunter Lovins to Everyone: For a definitive debunking of Jevons paradox, see https://archive.thinkprogress.org/energy-efficiency-lives-devastating-debunking-of-rebound-effect-and-breakthrough-institute-3a0b8f582bb2/ 15:03:13 From Hunter Lovins to Everyone: Well said. 15:06:39 From Charles Hall to Everyone: Very nice talk! 15:08:33 From Hunter Lovins to Everyone: Wrong on natural gas. If you count fugitive methane, natural gas is as damaging to the climate as coal, and the various forms of storage make gas plants unnecessary in any but the next few years. 15:10:59 From Jean Dougherty to Everyone: We are right in the middle of replacing our natural gas furnace and air conditioner with one air source heat pump. We will not need to change our ducting. One other benefit of an air source heat pump is that it will work as a furnance and an air conditioner. 15:13:12 From Jeff Passmore to Everyone: What is the role of small modular reactors compared to heat pumps in achieving zero emissions in buildings? [SMRs can provide low-carbon electricity, while heat pumps can efficiently use any electricity to heat and cool buldings. This point was made, though perhaps not clearly enough. Ed.] 15:14:44 From Jeff Passmore to Everyone: Dave, perhaps the new federal ECCC Minister [Steven Guilbeault. Ed.] would be more willing to listen to Ralph's message--perhaps a message CACOR could help deliver? 15:15:41 From Derek Paul to Everyone: Derek to everyone: Addressing climate change is at least as difficult as defeating the Axis in WWII. 15:19:44 From Jeff Passmore to Everyone: Is it time to admit defeat on 1.5 degrees and focus on adaptation (of which heat pumps could be a part)? I have to leave--work to do on < www.scalingupconference.ca >. You can hear Ralph speak on Tuesday Nov 2 at 11:00 on a slightly different topic--more on bioenergy. 15:21:43 From Charles Hall to Everyone: I have much more to say in defense of Jevon's paradox, but was cut off (appropriately perhaps). Also I was "denied access" to Hunter's attachment on JP. [The link has been corrected. Ed.] 15:23:20 From Hunter Lovins to Everyone: OK, if we’re going to continue this fight on Jevons. See https://archive.thinkprogress.org/rebound-effect-the-breakthrough-institutes-attack-on-clean-energy-backfires-29355ca6a2b7/ 15:25:14 From Charles Hall to Everyone: I sure wish you did not use the word "fight." 15:29:05 From Hunter Lovins to Everyone: Here in Colorado commercial bids for 1,700 MW needed (58,000 bid) showed that wind/storage/solar came in at 3¢/kWh. Gas came in at 4¢/kWh. 15:29:37 From Hunter Lovins to Everyone: A true delight. 15:30:58 From Hunter Lovins to Everyone: Ralph, I have to run. Thank you for all of your years of work, and I am SOOO glad you are still doing your excellent work. Hugs, HL 15:40:06 From Mike Nickerson to Everyone: The greenest dollar is the one not spent.
