Build an interactive household electricity analysis tool that helps users understand which appliances and usage patterns contribute most to their electricity bills.
Allow users to enter appliance wattage, daily operating hours, standby consumption estimates, electricity tariffs, billing periods, and actual meter readings where available.
The application should calculate estimated energy consumption in kilowatt-hours, compare modeled consumption with actual bills, and highlight discrepancies.
Include:
Appliance-level energy and cost breakdowns.
Peak versus off-peak calculations when tariff data is supplied.
Seasonal and monthly usage comparisons.
What-if scenarios for reducing operating hours or replacing an appliance.
Payback estimates for proposed efficiency upgrades.
Detection of implausible input values and unexplained differences between estimates and bills.
A prioritized list of possible savings opportunities with transparent calculations.
Provide editable appliance profiles, charts, CSV import/export, and sample household data.
Clearly label modeled consumption separately from measured consumption. Account for tariff slabs, fixed charges, taxes, and subsidies when the user supplies them. Do not promise exact savings from estimated wattage or assume an appliance runs at its rated power continuously.
