Well, in the case of my refrigerator, I didn't do a 1:1 replacement. I got a much larger capacity one, about 30% more space, while not using any more energy (It actually uses less, but not really noticeable in my energy bill.) My energy company gave be a multi-hundred dollar rebate to upgrade to an HE washer, so it was objectively better for my wallet to upgrade. Now I'm using less water, gas, and electricity when doing laundry. About a few hundred a year less on top of the rebate I got upfront. The tankless water heater has no pilot light, so there's some savings there, but the real benefit was having unlimited hot water. Tankless water heaters are rated to last longer than tanks, allegedly, but I haven't had one long enough to know either way. Incandescent to LED was a no-brainer, each pair of LED lights was about $30 at costco and use 14% of the energy. They have already more than paid for themselves, not including the money saved by needing to run the AC less.
