Clean energy, like solar and wind power, is key to reducing carbon footprint and achieving sustainable development. But how can we students contribute? At home, it’s better to use solar power if (it is) affordable. Once (we are) aware of energy waste, remind family members to turn off unused appliances. At school, start a "Green Energy Club" to share tips on saving power. When more students join, our impact grows. Clean energy is not just a concept — it's a lifestyle. Let's embrace it now! $
