Part 3:

1. At home, I save energy in several ways. Firstly, I use low-energy light bulbs throughout the house. Additionally, I make sure to turn off all electric devices like TVs, radios, computers, and lights when we go out. For short distances, instead of driving a car, I prefer to walk or go by bike, and for longer distances, I opt for public transport.
2. One future means of transport that I find advantageous is the electric scooter. Electric scooters function on autopilot, making them easy to use and efficient. They are compact, safe, fast, and comfortable. Moreover, they consume very little energy and can carry one person, making them ideal for short urban commutes. In my opinion, investing in an electric scooter is a wise choice for convenient and eco-friendly transportation.
