Dummy Algorithm Docs

This function calculates the carbon footprint of a device based on its power consumption and usage time.

1. Define Constants

• avg_watts = 40: Assumed average power consumption of the device in watts.
• co2_per_kwh = 0.475: CO₂ emissions per kilowatt-hour (kg CO₂/kWh), based on an estimated energy mix.

2. Retrieve Device Usage

• Calls get_power_on_hours_from(device), which returns the total power-on hours for the device.

3. Compute Energy Consumption

• Converts power consumption to kilowatt-hours (kWh) using:

  energy_kwh = (power_on_hours * avg_watts) / 1000
  

• This accounts for the total energy used over the recorded operational period.

4. Calculate CO₂ Emissions

• Multiplies the energy consumption (kWh) by the CO₂ emission factor:

  co2_emissions = energy_kwh * co2_per_kwh
  

• This provides the estimated CO₂ emissions in kilograms.
