And the house smells DEVINE!
My wife would be very NOT happy with the house smelling strongly of coffee.
One would have thought that it was within everyones long term interest to use less energy
Yes but (isn't there always a "but"?)
Prior to the "climate change" issue, efficiency meant replacing current electric devices with similar ones that use less electricity. Replace your electric dryer and water heater with natural gas or propane. Same with your kitchen stove (cooker for you Brits

).
But: we are supposed to get off fossil fuels due to climate change. Here people mostly heat with fuel oil, propane or for those closer to cities, natural gas. What do you replace the furnace with? Heat pumps and they use electricity. Substantially less electricity than resistance heat units but way more than oil/gas furnaces.
Vehicles burn gasoline or diesel. What do you replace them with? Electric or plug-in hybrids, both use electricity. I don't know how much electricity my Prius Prime used in the last 1,500+ miles (2,414 km) (since September) but I used only 8 gallons (30 litres) of gas. My wife uses between 20 and 30 kWh daily (seasonally dependant) commuting in her all electric Leaf.
So you end up using MORE electricity no matter how efficient you try to be with what you have.
So far the net connected solar arrays have annually covered the total electric usage for the cars and the house. Installed 2015 and 2020 (when we got the Leaf)
