1. Turn off the lights when not in use to avoid unnecessary energy waste. Leaving lights on unnecessarily can lead to higher electricity bills and unnecessary carbon emissions.

2. Make the most of natural daylight. Use artificial lighting only when necessary. This not only saves energy but also helps reduce eye strain and improve mood.

3. Choose lighting fixtures wisely. Avoid using frosted glass or translucent lampshades that block or diffuse the light too much. Proper lighting design ensures efficiency and comfort.

4. Use energy-saving lamps whenever possible. They can save up to 70% to 80% of energy compared to traditional incandescent bulbs. For example, instead of using a 60-watt bulb, an 11-watt energy-saving lamp will provide the same brightness.

5. Always turn off appliances when they are not in use. Even in standby mode, devices consume power. Turning them off completely can help you save about 10% on your electricity bill.

6. Use your refrigerator efficiently to reduce energy consumption. Avoid opening it frequently, don't overfill it, and keep it away from heat sources. Regular cleaning and defrosting also improve its performance and save energy.

7. Optimize washing machine usage by selecting the right program for each load. Try to wash full loads rather than small ones, and check the belt periodically to ensure smooth operation.

8. Maintain your air conditioner properly. Clean the filters regularly to improve airflow and cooling efficiency. Set the temperature at a reasonable level to reduce the workload on the compressor.

9. Adjust the brightness and volume of TVs, computers, and other electronics to save energy without sacrificing comfort.

Tip: If every city could save just 1 kWh per day, the collective impact would be enormous. A single city could save 15 million kWh daily, which equates to saving 6,000 tons of coal and 60,000 tons of water—making a huge difference in reducing environmental impact.

The Impact of One Kilowatt-Hour of Electricity

A 25-watt bulb can shine continuously for 40 hours. A household refrigerator can run for a full day. An electric fan can operate for 15 hours straight. An air conditioner can run for 1.5 hours. It can boil 8 kilograms of water. A TV can be on for 10 hours. An electric shower can be used for one person’s bath.

Saving 1 kWh of electricity is equivalent to saving 0.4 kg of standard coal, 4 liters of water, and reducing emissions like 0.272 kg of carbon dust, 0.997 kg of CO₂, 0.03 kg of SO₂, and 0.015 kg of NOx. If every person in a city saves 1 kWh per day, the overall savings would be remarkable—reducing electricity consumption by 15 million kWh daily, saving 6,000 tons of coal and 60,000 tons of water. This shows how even small individual actions can have a big impact on sustainability and energy conservation.
