  The blog post is an incredible read.

  My partner and I backcountry ski, iceclimb etc. One of the reasons we went with the Ioniq 5 was that we can sleep in the back and use the heat pump to keep us warm.

  We recently did a weeklong ski trip with it. We drove from from Golden, BC back to Calgary, AB (250km/150mi) in -16C (3F) and used 70% of a charge. One day on that trip, we were backcountry skiing in similar weather and the car sat outside in that weather for 8 hours. No loss of battery.

  One of the unexpected features I really enjoy is that I never pump gas in the cold any more. I programmed my work schedule and the car pre-warms for my commute. I get home, plug the car in, and it’s always ready to go.

  I live in Alberta where most of our power comes from natural gas. I’m also an emissions and sustainability engineer. I did the math on environmental payback for an EV where I live and the EV is WILDLY better for the environment despite the power potentially coming from fossil fuels.

  If you tell me roughly where you live I can calculate emissions per kilometre/mile including the energy that goes into manufacturing the vehicle.

  There’s absolutely jurisdictions where EVs don’t make much difference - but most places they do.

  (large scale power generation is pretty effecient and most jurisdictions have some renewables in the mix. A car’s gas engine is much lower efficiency most places)

• ⁨Comment⁩ on ⁨Solar should be packaged with consumer appliances⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  My (large) fridge hasn’t even pulled 1kWh today. Modern fridges are impressively efficient.

  I’m steadily electrifying my life - and adding solar panels as I go.

  Solar is already super modular and if you package the panels, then you rob the consumer of the ability to pick a panel that works for them (physical size for example, but where you live will also have a big impact on capacity requirements). Also, solar panels have a lifespan that exceeds most consumer appliances. I just replaced a ten year old stove but my solar panels have a 25 year warranty. The replacement cadence is very different.
