I asked ChatGPT to give me 10 tricks to save electricity this summer in Mumbai. I wanted hacks that most people don’t know about. Here’s what the AI had to say.
ChatGPT tailors its advice specifically to households in Mumbai. It envisages a 2BHK family using 250-600 units per month. One or two rooms have air conditioning. Mumbai’s weak billing means that every unit saved is counted twice. Exceeding a higher plate increases the cost of each unit, not just the extra ones.
The biggest villain
ChatGPT identifies AC as the single largest consumer of electricity. A 1.5 ton AC consumes roughly 1-1.8 units per hour. Mumbai’s humidity keeps the compressor running harder than in drier cities.
The fix is simple: set the air conditioner to 26°C and turn the ceiling fan to minimum. The fan circulates the air so 26°C is like 24°C. The compressor runs less because the temperature gap is smaller. Monthly savings can range from ₹700 to ₹2,500 for AC. The cost of this change is zero.

Cleaning the AC filters every fortnight is equally important. Mumbai’s coastal air clogs filters faster than inland cities. A clogged filter makes the compressor work longer. Regular cleaning saves money ₹300– ₹1200 per month.
ChatGPT also warns against setting the AC to 18°C. It doesn’t cool the room faster in any meaningful way. It just keeps the compressor running longer. Dry mode is recommended for humid evenings when the heat is not intense.
Silent Power Drains
Standby power is a silent but constant load. TVs, set-top boxes, routers and old desktop computers use energy even when they are turned off. One charger costs very little per month. But the TV and set-top box together can be expensive ₹50– ₹150 per month.
ChatGPT recommends switchable extension cables for these devices. Investment is ₹300– ₹800. Monthly savings range from ₹100 to ₹400.

Refrigerator
Most households run their refrigerator on an unnecessarily cold setting. ChatGPT recommends 3-4°C for the fridge and -18°C for the freezer. Hot food placed directly inside the compressor makes it work harder.
The refrigerator also needs breathing space behind it. A capacitor stuck to the wall silently wastes energy. The seal test is simple: close the door on a sheet of paper. If it slides out easily, cold air is escaping. Seal cost fix ₹0– ₹1500 and save ₹150– ₹600 per month.
Savings Hacks from ChatGPT(ChatGPT)
Fans, geysers and washing machines
Old fan controllers waste electricity as heat. Electronic regulators are better. The best are BLDC fans, which only use 28-35 watts versus the standard 70-80 watts. Replacing highly used fans with BLDC models saves money ₹150– ₹500 per fan per month. The price is in advance ₹2000– ₹3,500.
A 2kW geyser running 45 minutes a day consumes 45 units per month. ChatGPT recommends a timer that only heats the water before bathing. This saves money ₹250- ₹700 per month. Washing machines should always be run on a full load with cold water. Water heating is the expensive part.

Smart meter and billing tricks
Time of day billing in Maharashtra rewards daily device usage. Operation of the washing machine, iron and pump between 9 am and 5 pm is cheaper. Avoiding heavy loads between 18:00 and 23:00 reduces peak charges. Monthly savings are ₹100– ₹500 at zero cost.
ChatGPT also recommends keeping a close eye on your daily unit usage. A jump from 300 to 500 units will move the entire account to a higher plate. Consumers should also check their approved load. Excessive sanctioned load results in unnecessary fixed charges every month.
A hidden threat
Bad wiring is both a safety risk and a cost issue. ChatGPT recommends turning off all appliances and watching the meter.
If it’s still moving, there’s probably been a leak or an unauthorized tap. Warm switchboards, flashing lights and frequent MCB tripping are red flags. Fixing a real fault will save ₹200– ₹2000 per month.
With these hacks, a typical Mumbai 2BHK family can reduce consumption by 15-30% without sacrificing comfort.
