So just curious, how does it compare bringing 40 degrees Celsius down to 21 degrees, vs 0 degrees upto 21 degrees. Is heating more energy efficient than cooling? My practical experience has been that AC costs less, than heating a home.
Considering that if anywhere Solor panels could work well, the Dubai desert is near tops for efficiency. This also offsets any deficit. And Dubai also has seasonal temperature variations, winter they are around 29 degrees.
I wouldn't be surprised that the total energy expenditure for a home in Dubai, is less than a home in Northern Canada .
- bena 5y agoSome quick checking and Dubai is around 12,000 kwh per year per household and California is around 6000 per year per household. My point was that A/C is really just changing the equilibrium of a small area. Making a building cooler means you have to make some other area warmer.
