Energy Saving Opportunities & Recommendations

Actionable steps to lower your monthly power consumption and electricity bills:

💡

Switch Off Geyser Promptly After Bathing

Using a timer or turning off water heaters promptly prevents standby reheating cycles, saving ~30% heating energy.

Potential Savings: ₹115.08 / month(₹1,380.96 / year • 18.0 kWh/mo)
💡

Turn Off Wall Sockets (Eliminate Vampire Power)

Unplugging chargers and turning off switchboards for TVs, gaming consoles, and appliances saves ~5% standby power.

Potential Savings: ₹67.71 / month(₹812.52 / year • 10.6 kWh/mo)

Frequently asked questions

What is 1 unit of electricity?

One unit of electricity equals 1 kilowatt-hour (kWh). It represents using 1,000 watts of electrical power continuously for one hour. For example, a 100W light bulb switched on for 10 hours consumes 1 kWh (1 unit).

How do telescopic slab tariffs work in India?

Most Indian state electricity boards (DISCOMs such as BESCOM, TANGEDCO, MSEDCL, UPPCL) use telescopic slabs where different portions of your consumption are billed at progressive rates. The first 100 units are billed at a subsidized rate, the next 100 at a higher rate, and higher tiers at the highest rate.

Which household appliances consume the most electricity?

Air conditioners (1,200W–1,800W) and electric water heaters / geysers (2,000W–3,000W) are typically the largest contributors, accounting for 50% to 70% of a typical summer or winter household electricity bill.

How much electricity does an inverter AC save?

A 5-star inverter AC consumes approximately 30% to 40% less electricity than an older non-inverter AC because its variable-speed compressor slows down once the desired room temperature is attained rather than cycling abruptly on and off.
