As the saying goes “if you can’t measure it, you can’t manage it
It’s much easier today to measure your power usage, there are a number of different ways ranging from the freely available broad brush approach to more specific options that allow you to measure individual devices.
When you measure your power usage you take back your control and you can choose how much you use. Measuring your power use will also help you to understand not only your current cost but also any future reductions you enjoy by changing your habits or your devices.
The great benefit is that you get to choose what you do and how much you spend.
