I'm going to attempt to create a thread expressing the difference between market and government driven.

I have a Bolt, and a Tesla...
Last winter Liz and I took the bolt to the Adirondacks (she had a role in Escape At Danemora). The trip up took us 12 hours instead of 6 because of the time spent charging.

We slept in a grocery store parking lot.
😐😪
The total trip was about 700 miles.

The car spent 27 hours charging. One night we spent in a motel, so taking that 7 hours off we spent about 20 hours waiting for the car.

In Malone we had no plan, and got lucky the Chevy dealer had a charger and was a generous soul.
This is what the "fast" network may look like in NY in a year or two:
This is Tesla's current network as of Jan 1, 2019:
We drove the Tesla to Florida in January.

We stopped more to service our needs than we did for the car.

We never waited for the car. It was always ready before we got back to it.
We really like the Bolt, but it's a very limited government compliance car.

It doesn't excite the market.

The Tesla excites the market.

Don't take my word for it, look at sales:
If we are going to decarbonize transportation we need to get to MILLIONS of cars a year, quickly.

For that to happen, people have to BUY them.

Same for decarbonizing homes. We have to have a way to do it that sells, at scale.
If you aren't decarbonizing homes at ALL, please stay out of the way of those of us who are?

YOU ARE IN THE WAY.

If you ARE doing it, please share your process, costs, and results so we can figure out how to scale.

Without a process that scales...
Nothing will get fixed.

Nothing will get done.

Carbon and pollution goals won't be achieved.

Whining without solutions isn't helpful.

it's indication of a big, ineffective self serving virtue signaling circle jerk.

Tesla FORMALLY notified me Saturday that there's a car waiting for me at Mount Kisco.

Mount Kisco is 350 mi from me.
I first found out that this car had been built on Monday when I got a call from the carrier direct rep asking if I wanted the car shipped to me.
I'd originally ordered the car for March-April delivery, and waved It off when in February they told me the car had arrived and that I would need to pick it up in the middle of a snowstorm.

On 11/6/17 I attended a seminar: Pursuit & Discovery of Vehicle Electrification Markets presented by Mark Mathias, Director of Fuel Cell R&D at General Motors
I was really impressed by the guys wisdom and perspective.
At that time it was obvious to him that BEV had won.

The hydrogen exercise had been worthwhile for a number of reasons.

It removed lingering doubt.
It helped create a competitive environment.

Also, a lot of tech had been developed that could be deployed elsewhere.

Etc...

Our business fixes problem houses.

We provide education, diagnostics, comprehensive design, work scopes, and quality control/assurance.

We also track outcomes.

We always offer an Electrification path.

The greatest barrier to Electrification?...
It is NOT the consumer.

We consulted with @drvox on his home renovation.

Anyone think he ran a gas line and committed his home to Fossil Fuels for the foreseeable future because he didn't WANT to electrify?

NFW....
IT'S THE CONTRACTOR.

Over and over we see consumers across the country discouraged from Electrification by contractors.

We think Passiv is important aspirationally. Those who try to make it more are advocating for a world that overspends on EE.

You set your goals too low and achieve them, you don't know how far you could have gotten.
For example, air sealing. Most set a goal and stop when they reach it
In our practice we set multiple goals, and have been continuously surprised by how far the first goal is exceeded.

HVAC 2.0 requires 3 load calculations.

Current explanation of "3 loads":
The first Manual J shows how much infiltration is needed to make your current equipment properly sized.
The second Manual J calculates the worst case heat gain and heat loss given your homes current condition.

Energy Efficiency may once have been the cheapest resource, but more and more that is not holding true.

Our EE projects have 50-1000 year paybacks.

Solar typically has 6-20 year paybacks.

(Obvious yet?)
So if solar cost $2-5 a watt,

And EE costs $10-100 a watt,

Once the Stacking Benefits of incremental energy efficiency are all harvested,

...putting additional money into Energy Efficiency instead of putting it into solar is arguably BAD for the environment.
