Two problems that seem unrelated — your rising electricity bill, and the carbon heating the planet — have exactly the same solution: using less electricity to get the same comfort. Every unit of power you don't waste is money back in your pocket and less coal burned for the grid. It is the rare fix that is good for the wallet and the world at once.

You don't need solar panels or a big budget to start (though rooftop solar is worth it if you own your roof — see our PM Surya Ghar guide). A handful of cheap, practical changes can cut a typical household's bill by a quarter or more, and keep saving every month for years. Here is what actually works, roughly in order of impact.

1. Buy the Right Appliances (the Star Label Matters)

The single biggest long-term saving is choosing efficient appliances, because a fridge or AC runs for years. When you buy a fridge, AC, fan, geyser, TV, or washing machine, look at the BEE star rating label — more stars means less electricity for the same performance. A 5-star AC uses about 25–30% less power than a 1-star model for the same cooling. The 5-star version costs a bit more up front but pays back the difference in a couple of summers and keeps saving after.

For fans, choose a modern BLDC (brushless) fan — it uses roughly half the power of an ordinary fan and runs cooler.

2. Tame the Air-Conditioner

In summer, cooling can be half the bill — so small AC habits make a big difference:

  • Set the AC to 24°C, not 18°C. Every degree you lower it adds roughly 6% to the bill — and 24°C is comfortable and healthy. The government now sets 24°C as the default.
  • Use the timer and sleep mode, and close doors and curtains so you're not cooling the outdoors.
  • Clean the AC filter monthly — a clogged filter makes it work harder for less cooling.
  • Run the fan with the AC so cool air spreads and you can keep the temperature a little higher.

3. Switch Every Bulb to LED

If you still have any old incandescent or CFL bulbs, replace them with LED bulbs. An LED uses up to 90% less electricity than an old bulb for the same light and lasts years longer. It's a small one-time cost that keeps paying back every night.

The hidden drain: "phantom" power
Switch off at the wall — devices sip power even when "off"
Televisions, set-top boxes, chargers, microwaves, and Wi-Fi routers keep drawing electricity even when switched off by remote or left plugged in doing nothing — this "standby" or "phantom" load can quietly add several percent to your bill across a year. The fix is free: switch appliances off at the wall socket when not in use, and unplug chargers once the phone is full. Put the TV and set-top box on one switchboard you can flip off at night. It costs nothing and saves every single month.

4. The Free and Cheap Habits

None of these cost anything:

  • Use daylight — open curtains by day instead of switching on lights.
  • Run the washing machine and geyser with full loads / only as needed, and use the geyser timer so it isn't heating water all day.
  • Set the fridge to a medium setting, don't leave the door open, and let hot food cool before storing it.
  • Iron clothes in one batch rather than one at a time (the iron uses a lot of power heating up).
  • Maintain what you have — clean fan blades, fridge coils, and AC filters so everything runs efficiently.
Start with the three that save most

You don't have to do everything at once. Start with the big three: set the AC to 24°C, switch every bulb to LED, and buy 5-star rated appliances when you next replace a fridge, fan, or AC. Add the free habit of switching off at the wall to kill phantom power. Together these can cut a household bill by a quarter or more — money saved every month, and carbon saved every day. And if you own your roof, rooftop solar (PM Surya Ghar, up to ₹78,000 subsidy) can take the bill close to zero.

What You Can Do

  • Buy 5-star (BEE-rated) appliances — fridge, AC, fan, geyser — for 25–30% less power over their life.
  • Set the AC to 24°C, clean the filter monthly, and close doors/curtains while cooling.
  • Replace all bulbs with LEDs and choose BLDC fans for big savings.
  • Switch off at the wall to kill standby/phantom power; unplug full chargers.
  • Use daylight, full laundry loads, and a geyser timer; let hot food cool before refrigerating.
  • Maintain appliances — clean filters, coils and fan blades so they run efficiently.
  • If you own your roof, look into rooftop solar under PM Surya Ghar for a near-zero bill.

Saving electricity is the easiest climate action there is, because it pays you to do it. A few smart choices and free habits shrink your bill and your carbon footprint at the same time — starting with your very next bill.

Frequently Asked Questions

What is the fastest way to reduce my electricity bill?
In summer, set your AC to 24°C (each degree lower adds about 6% to the bill), switch all bulbs to LEDs, and switch appliances off at the wall to kill standby power. Over the longer term, buying 5-star BEE-rated appliances gives the biggest savings.
Do BEE star ratings really make a difference?
Yes — a 5-star appliance uses roughly 25–30% less electricity than a 1-star one for the same performance. Since a fridge or AC runs for years, the slightly higher purchase price pays for itself in a couple of seasons and keeps saving after.
What temperature should I set my AC to?
24°C — it is comfortable, healthy, and efficient, and is the government's default setting. Lowering it to 18°C can add around a third to your cooling cost for little extra comfort.
What is "phantom" or standby power?
The electricity that TVs, set-top boxes, chargers and routers keep drawing even when switched off by remote or left plugged in. It can add several percent to your yearly bill. Switching appliances off at the wall socket stops it, for free.
Is rooftop solar worth it for cutting the bill?
If you own your roof, yes — under PM Surya Ghar you get a subsidy of up to ₹78,000 and a typical system can cut your bill to almost nothing for 20+ years. See our PM Surya Ghar guide for the step-by-step.
