Energy Consumption Linux

This repository contains a Bash script that estimates the daily, monthly, and yearly energy consumption of your system based on hardware information and user-specified active hours. The script gathers system details using standard Linux utilities and applies usage coefficients to calculate estimated power usage in kilowatt-hours (kWh).

Usage

1. Copy the Script:
   Save the script (e.g., as energy_estimation.sh) to a location on your system.

2. Make it Executable:

   chmod +x energy_estimation.sh

3. Run the Script: sudo ./energy_estimation.sh

Note: Running as sudo may be necessary since some commands (like dmidecode) require root privileges.

Requirements

Operating System: Linux

Dependencies:

Ensure the following commands are installed:

- lscpu  
- lsblk  
- dmidecode  
- lspci  
- bc  
- free  
- xrandr  
- usbutils  

=> sudo apt update && sudo apt install util-linux dmidecode pciutils bc procps x11-xserver-utils usbutils

Features

• Dependency Check:
  The script verifies that all required commands (e.g., lscpu, lsblk, dmidecode, lspci, bc, free, xrandr, lsusb) are installed. If a dependency is missing, it prompts you with an installation command.

• User Input for Active Hours:
  Prompts the user to enter the number of active hours per day (between 0 and 24). The remaining hours are considered idle.

• System Type Detection:
  Uses dmidecode to detect the chassis type (e.g., Desktop, Tower, Gaming) and adjusts energy consumption multipliers accordingly.

• Component-wise Energy Calculation:
  Estimates the daily energy consumption (in kWh) for:

  • CPU: Based on the TDP value and usage multipliers.
  • GPU: Detects the GPU type and applies corresponding coefficients.
  • Motherboard/Chipset: Uses fixed active/idle consumption values.
  • RAM: Calculates consumption from total memory and predefined active/idle rates.
  • Storage Devices (SSD/HDD): Determines consumption from the number of devices and their active/idle power ratings.
  • Screen: Considers active power usage.
  • Other Components: Includes peripherals like WiFi, Bluetooth, and fans.

• Power Supply Losses:
  Takes into account PSU efficiency (default 87%) to estimate additional losses, providing a more realistic total consumption figure.

• Detailed Summary:
  Displays:

  • Consumption per component (CPU, GPU, motherboard, RAM, storage, screen, others).
  • Subtotal consumption (without PSU losses) and the estimated losses.
  • Total estimated consumption per day, as well as extrapolated values for monthly and yearly usage.
  • Average power in Watts computed from the total daily consumption.

• Hardware Details:
  Outputs key hardware information such as the CPU model, GPU details, total RAM, SSD/HDD count, and connected USB devices.
