One of the challenges of constructing one will come from the varying time - spans that different types of generating machinery operate and different types of
electricity consuming equipment need power.
By enabling the linking, monitoring, aggregation and control of large numbers of individual pieces of
electricity consuming equipment, connectivity allows for matching demand to the needs of the overall system in real time (Digitalization & Energy, 2017).
Not exact matches
What I suggest isn't trivial nor impossible, though, just FYI a quick Google gave this magnitude: «At least 11 % of the
electricity consumed in German households and offices is used by temporarily unused
equipment running in stand - by mode.»
(This is not absolutely true; energy is taken from the wind, but that is without any sort of cost that anyone has identified, and if the wind isn't blowing the turbines do
consume a little
electricity to run various
equipment.)
But the utility shut down the carbon capture
equipment in 2011 because it could not sell the carbon dioxide or recover the extra cost from its
electricity customers, and the
equipment consumed so much energy that, at full scale, the project would have sharply cut
electricity production.
This increases cooling loads in summer, requiring larger HVAC
equipment and
consuming additional
electricity, which in turn exacerbates air pollution and contributes to the formation of smog.
In some ways it is quite generous, give that, if you can afford to install the
equipment then you will get money from your
electricity supply company, even for the power you
consume yourself that you have generated.
