First house, about 50+ years ago, insulated, double windows etc. oil for heating. Oil system operated without electrcity. Oil was then relatively cheaper and electrical supply then not reliable.
Current house about 39 years, all electric heating. Electricity in this region now highly reliable, almost 100% hydro generated and now relatively cheaper. Also electricity considered ecologically 'friendly' . Very happy with decision back then, to go all electric. BTW there is no requirement here for AC; every month of year requires 'some' heating, especially at night when lights tend to be on.
So been feeling pretty good about our 'non-polluting' energy source and therefore a presumably small carbon footprint!
Question: But even though we are using a supposedly more ecologically friendly energy source than burning also polluting fossil fuel (oil, gas, coal etc.) the heat and other energy generated from the electrcity that comes into the home does escape into the environment!
So does that 'add' to global warming? Asking because cold water running down a river would not seem to add heat to te environment? Whereas after turning it into heat and allowing it to escape into the environment does so???????
In summary; cold water running by gravity down rivers hundreds of miles away drives electrcity generators. That electrcity is brought by high voltage transmission lines (with some losses) to our homes.
Where most (if not all ) of it is turned into heat in one form or another. No matter how efficient our lights and appliances and electric heating and cooking, TVs, computers, house tools etc.
So from an environmental viewpoint is our home acting as heat generator? It is of course well known that even in the coldest regions cities are a few degrees warmer because of the energy/heat loss from its buildings.
Curious: Because cold water running down a river would not seem to be adding any heat to the environment? Whereas turning its energy into electrcity and then heat which then escapes from our home might do so???
Rationale discussion/disagreement anyone?
