Problem Statement :

Electricity consumption in households is often poorly understood because users typically receive only a monthly electricity bill without detailed information about how individual appliances contribute to overall energy usage. This lack of visibility makes it difficult for people to identify inefficient appliances or adjust their consumption habits.

As a result, many households experience higher electricity costs and increased environmental impact due to unnecessary energy usage.

There is a need for a simple and accessible system that helps users monitor appliance-level electricity usage, understand their energy consumption patterns, and make informed decisions to reduce energy waste.

Solution :

GreenPulse is a web-based platform designed to help users monitor and analyze their household electricity usage. The system allows users to manually add appliances, specify their power ratings, and track usage patterns. Based on this information, GreenPulse calculates energy consumption and estimates electricity costs using tariff slab calculations.

The platform provides consumption analytics, goal tracking, and energy-saving recommendations to encourage responsible electricity usage and improve energy awareness.

Key Features :

Appliance Management

• Add household appliances with power ratings

• Enable or disable appliances

• Track energy usage per appliance

• Manage appliance list easily

Energy Consumption Tracking

• Calculate electricity usage based on power and time

• Monitor daily, weekly, and monthly consumption

• Visualize usage trends through analytics

Electricity Cost Estimation

• Implements tariff slab pricing

• Estimates electricity bill based on energy usage

• Helps users understand how consumption affects costs

Energy Usage Goals

• Users can set monthly electricity consumption goals

• Track progress toward goals

• Promote energy-efficient habits

Energy Saving Tips

Database

Workflow

1. User logs into the platform

2. User adds appliances and usage data

3. Backend calculates energy consumption

4. Data is stored in the database

5. Dashboard displays analytics and usage insights

6. Background tasks periodically update consumption data

Technology Stack :

Frontend

• React / HTML / CSS

• JavaScript

Backend

• Python

• FastAPI / Django

Database

• PostgreSQL / SQLite

Background Processing

• Celery

• Redis

Data Processing

• Energy calculation logic

• Tariff slab cost estimation

Energy Calculation Model :

Energy consumption is calculated using:

Energy(kWh)=Power(W)×Time(hours)1000Energy (kWh) = \frac{Power (W) \times Time (hours)}{1000}Energy(kWh)=1000Power(W)×Time(hours)​

Example:

Appliance: Air Conditioner
Power: 1500 W
Usage Time: 2 hours

Energy = (1500 × 2) / 1000
Energy = 3 kWh

The system aggregates this data to estimate total consumption and cost.

Conclusion :

Users can set monthly energy consumption goals to encourage energy-efficient habits. The system tracks progress toward these goals and provides insights into current consumption levels. GreenPulse also displays helpful energy-saving tips and environmental suggestions to promote sustainable energy usage.

The platform includes an administrative interface that allows administrators to manage users, monitor appliance data, and view system analytics.

GreenPulse currently uses manual appliance data entry instead of IoT-based smart meters. This design allows the platform to operate without specialized hardware while still providing meaningful energy consumption insights. The system can be extended in the future to integrate IoT sensors or smart meters for automated data collection.

Overall, GreenPulse aims to improve energy awareness, encourage responsible electricity consumption, and help users make informed decisions to reduce both energy costs and environmental impact.
