Scoring Algorithm

Unfortunately, we can't display every part of the power grid on one light, but we can “summarise” that information into one metric. That summarisation process is called a Scoring Algorithm. That metric is configurable, and there are lots of options. Here's my favourite two:

Cumulative CO2e Emissions

This is the default metric used for your Micro-Indicator

The total CO2e being released by New Zealand's grid at this moment, in Tonnes/hour. Heavily influenced by the current power output of the grid, making it cycle on a daily basis. It shows how "strained" the power-grid currently is.

CO2e Intensity

The amount of extra CO2e emitted by the grid if you turned on an appliance, in gCO2e/kwh. Heavily influenced by sources of power and the operational status of power-plants, meaning it has much longer cycles than the Cumulative Output.

Changing the Scoring Algorithm

To change how your light reacts to the power grid, you'll need to start by looking in src/powerstations.cpp
