Reply to comment by ThePrem in New solar capacity 10 times cheaper than gas, says intelligence company Rystad by EnergyTransitionNews

You’re shifting the goalposts. Plenty of NY homes are electrifying now, especially because it ends up being more cost effective than gas. The fact that gas prices keep hopping off the rails here every winter while solar is getting cheaper and cheaper is only going to exacerbate this trend.

> electric heat is less efficient

Please source this assertion as it flies entirely against the prevailing scientific consensus.

> cold/dark

Again, this is nothing but a hollow truism and completely ignores the last couple of decades in building science and scientific achievement in PV. Sorry but it just doesn’t seem like you have any idea what you’re talking about.

I think you are confused...people are electrifying but generally not for heat. Here is a good reference for heating power sources and pros/cons and why electric heat is less efficient. This is generally accepted among the HVAC industry and is not anything controversial.

Basically it boils down to gas burning hotter than an electric coil and getting more efficient heat transfer due to a higher temperature difference between the air you are trying to heat and the heat source.

I also don't think its controversial to suggest that there is variability in solar panel efficiency in different regions. I provided a link below that shows the difference. Someplace like Arizona where there is more direct sunlight for longer periods in the day will have a higher efficiency than Iceland where theres 5hrs of daylight in the winter and its overcast often.

The cost benefit analysis for someone in NY who uses more heat and has lower efficiency with their solar panels is completely different from someone who lives in Florida where there is a low heat load and plenty of sunlight.

Again, I am not sure what I am saying that is so controversial or shifting goal posts.
