How hot does a 50-watt incandescent lightbulb get? That's what an extra 50 watts of wasted power will feel like.

My house is cold, the extra heat is welcome here. I only have electric heat.

Unless you live in the tropics, electric heat is borderline unconscionable with regards to climate change.

Why is that? Your electricity might be from renewable resources. Or a non-renewable that is more efficient in total than using gas directly.

My choices are grid, solar, propane. I only use propane as emergency power backup.

I use solar power. Also, in nearby San Jose, California, they have banned NG in all new construction except commercial or multi family residences taller than 3 stories.

what's the conscionable alternative?

Wear a sweater.
