How much can an LED swap really save?

Replacing ten 60W bulbs with 9W LEDs used 3 hours per day can save around 46 kWh per month, which is roughly $7–$12 depending on energy rates.

Is a smart plug worth it?

Smart plugs are useful for standby loads or fixed schedules. Turning off 20–40W for 18 hours a day saves roughly 11–22 kWh per month.

What’s the best thermostat setting?

Aim for comfort first; each 1°F change can alter HVAC costs by about 3–5%. Use fans so you can keep setpoints a bit higher in summer or lower in winter.

How do I find my biggest energy hogs?

List appliances, estimate runtime, and run them through the WattWise calculator. Prioritize devices that run many hours and draw high wattage.

Green Energy Tips

Why Saving Energy Matters (for Your Wallet & the Planet)

Most homes overspend on electricity due to a few habits and inefficient devices. The good news? You can trim 15–30% from your bill with simple changes — no tech degree required. Start with quick wins, then move to bigger upgrades when they actually pay back.

1–3 yrs Payback for common upgrades (LEDs, smart plugs)

Five High-Impact Strategies You Can Start Today

1) Kill Standby & “Vampire” Loads

Routers, set-top boxes, consoles and chargers sip power all day. Put entertainment centers on a smart plug and schedule off-hours.

Look for warm power bricks — they’re using energy.
Group devices (TV + console + speakers) on one switch.

2) Dial in AC & Heating

Each 1°F (~0.5°C) change can shift HVAC costs by 3–5%.

Summer: set 24–26°C (75–78°F). Winter: 19–21°C (66–70°F).
Use fans to feel cooler at higher setpoints.

3) Lighting = Fast Payback

Swap remaining incandescents/halogens for LEDs (use 80–90% less).

Match brightness by lumens, not watts.
Choose 2700–3000K for warm rooms; 4000–5000K for tasks.

4) Tame Hot Water

Hot water can be 15–25% of a home’s energy. Shorter showers + efficient showerheads = real savings.

Set heater to ~49–54°C (120–130°F).
Fix drips; insulate the first 2–3m of hot pipes.

5) Measure to Manage

Use our WattWise calculator to estimate what each appliance costs monthly — then cut the worst offenders first.

Prioritize long-runtime devices (fridges, AC, pumps).
Check kWh on bills; track a 30-day before/after.

Quick Mini-Guides

Optimize Your Fridge in 90 Seconds

Set 3–4°C (37–40°F) fridge, −18°C (0°F) freezer.
Vacuum coils twice a year; keep 5–7 cm airflow around.
Replace failing door gaskets; a paper slip test should “grab.”

AC Efficiency Cheats

Clean filters monthly in season.
Close sun-facing blinds at midday; use ceiling fans.
Seal gaps around windows/doors to stop hot air infiltration.

Frequently Asked Questions

How much can an LED swap really save?: Replacing ten 60W bulbs with 9W LEDs (3 hours/day) saves ~46 kWh/month, which is roughly $7–$12 depending on local rates.
Is a smart plug worth it?: Yes for devices with standby draw or fixed schedules (TV setups, water dispensers). If it lets you turn off 20–40W for 18 hours/day, that’s ~11–22 kWh/month saved.
What’s the best thermostat setting?: Comfort first, then nudge setpoints: each 1°F change can shift HVAC costs by ~3–5%. Use fans to boost comfort without dropping the temp as much.
How do I find my biggest energy hogs?: List appliances, estimate runtime, and run them through the WattWise calculator. Target long-runtime, high-wattage items first.
