PowerTOP is a Linux tool created by Intel to monitor and diagnose power usage by running apps and services
“It's best used for devices with internal batteries, and you need a way to work out what's draining your internal power source between charges, or those that run continuously, and efficiency is a priority. It's interesting in that the tool lets you manipulate power management settings to experiment with different configurations. Released in 2007, the tool has since been updated to work with modern hardware.”
Modern power supplies adjust their power usage according to their loads over time, so apps or services using a lot of processing power over time, are going to use more energy. This is especially noticeable if the device is battery powered like a laptop.
This also does not only work for Intel processors, but also AMD and ARM as well.
The linked article also has a link at the end to another similar tool as well, which exports to Prometheus.
