Over the century, humans have tried to reduce energy usage and conserve resources. One efficient way is to build green homes. Many modern cities have started using this method in recent years to help the environment, including countries like Malaysia. There are a few key ways to build green homes, such as using recycled materials like steel, glass, and aluminum to reduce waste. Another method is installing energy-efficient products in the home, like LED lights and eco-friendly air conditioners, to decrease energy usage and help address climate change caused by fossil fuel consumption. Building green homes can conserve the environment through recycling materials and saving energy.
