Jason GormanIn a nutshell
jon r@jasongorman
I don't really get it, but it sure does sound nice. What's the aha-moment here about the anti-proportional relationships between efficiency, effectiveness, needs and resources that I am missing?
@joe_vinegar
Jon Moore@yala @jasongorman @joe_vinegar An efficient system does not waste resources, at the possible expense of not meeting every need. An effective system meets every need, at the expense of some of the resources being idle sometimes (“wasted”).
catch@jonm @yala @jasongorman @joe_vinegar that's not how I read things for efficient.
If you look at a grid, It's more like charging batteries/heating water etc when there is excess solar/wind and/or low demand, which results in stored energy that then doesn't need to be taken direct from the grid when there's higher demand or lower generation.
For example I set my home solar battery up so it charges at night when it's windy (based on 30 minute energy pricing from my supplier) and realised 99% of home solar installations don't do this. Neither efficient nor effective compared to what they could be, especially in the winter.
keplerniko@catch56 @jonm @yala @jasongorman @joe_vinegar Is that not an example of *optimisation*, rather than efficiency?
Your solar battery is supposed to store energy from the solar panels (alone). The fact you've found an additional use for it - to store energy from a different source - which helps maximise its *effectiveness* beyond the initial point of failure (i.e. when it runs out of charge from the stored solar energy alone) does not speak to its efficiency at its intended purpose (storing solar energy) but rather peak *optimisation* by finding more than a single way to charge it.
@keplerniko @jonm @yala @jasongorman @joe_vinegar no because the battery is one example of the grid as a whole.
Need available when resource becomes free (electricity):
Charging idle batteries, heating water, charge underground thermal energy storage - instead of shutting down wind turbines which is what can happen when there's nothing to absorb the electric from the grid.
Resource available when need arises:
Energy stored via the above methods can be used before gas plants, diesel generators, coal stations fired up, or rationing, power cuts etc. increasing the total energy available without additional grid load.
@catch56 @jonm @yala @jasongorman @joe_vinegar Ah sorry, I thought you meant your battery specifically, not all those which are theoretically available (as well as any other energy capture devices plugged to the grid) which could store overnight energy and release during the day.
