Two batteries of 12 V 9 Ah each. |

The only way you can figure out the real effect of each setting is using a power meter, which few people have access to. There are warnings in some manuals. For example, our LG TV manual says you can turn the TV on and off by bluetooth wifi or ethernet commands, but enabling this increases power consumption. They don't say how much it increases, but the fact that they provide a warning suggests the effect is pretty bad. I haven't checked the effect on our particular TVs, but in the past I found some standby settings increased a TVs consumption from a couple of watts to about 50W. Even a couple of watts is pretty bad. In 2022 its not hard to engineer a standby power level of a few milliwatts. Even being able to start from a bluetooth, wifi or ethernet command can be done for a small fraction of a watt. |

Yeah, really. ;D --- End quote --- Says the man in France with the cheapest electric in the western world or certainly Europe. --- End quote --- Uh yeah. Sure. Prices are inflating a lot over here as well though. And... On a more serious tone though, one thing that defies logic is that from what I know, the UK is almost self-sufficient energy-wise - at least for electricity and gas. They do not get any gas from Russia AFAIK, whatsoever. Please correct me if I'm wrong though. So how come prices are skyrocketing there? The UK is not even part of the EU anymore, so it's not a matter of decisions from the EC either. What is it? I'm curious and not the only one wondering, so if some enlightened people can explain this to us. The OP's title looks quite right. |

If you include them in your thinking then you are distracted from where the real problems are. Hot water heater !!!! Put an insulating blanket on your electric hot water heater. When you shower turn the flow rate of water down to a trickle. Don't reduce water temp ( that just miserable ) but the flow rate. At full on most of the hot water misses the body anyway. Refrigerator !! Other than making sure the seals are good and air flow is good around the unit not much you can do. Run the heat pump mainly when outside temp is favorable. In summer that is at night. In winter that is when the sun is on it. Favor microwave instead of oven of possible ( unless you heat with electric resistance heat ). More ideas ?? --- End quote --- I have a gas hot water heater so that doesn't affect my electric usage and costs relatively little to run anyway. My refrigerator is a relatively steady draw with a roughly 50% duty cycle that doesn't seem to change much. All the little stuff adds up quickly though, 5W here, 3W there, pretty soon you're talking significant power, my steady state base load is about 250 watts. I'm only paying a hair over 10c/kWh so I haven't put any great effort into reducing it yet but it does annoy me that there are so many random loads, I had a spreadsheet years ago but I haven't updated that in a long time. |
