Here are the top 10 ways that elderly people in the UK can save energy:

1. Insulate their homes: One of the biggest sources of energy waste in homes is poor insulation. By adding insulation to their homes, elderly people can reduce heat loss and save energy. This can include cavity wall insulation, loft insulation, and double glazing.
2. Use energy-efficient lighting: Switching to energy-efficient lighting can reduce energy usage and lower energy bills. This includes LED lights, which are highly efficient and long-lasting.
3. Install a programmable thermostat: A programmable thermostat can help regulate the temperature in the home, reducing energy consumption when the house is empty and increasing it when someone is home.
4. Use a kettle instead of a stove: When making tea or coffee, using a kettle is more energy-efficient than boiling water on the stove.
5. Wash clothes in cold water: Washing clothes in cold water can reduce energy consumption by up to 90%.
6. Use a microwave instead of an oven: Microwaving food is more energy-efficient than cooking it in an oven, as it takes less time and uses less energy.
7. Unplug electronics when not in use: Devices that are left plugged in use energy, even when they are not being used. Unplugging devices when they are not in use can save energy and lower bills.
8. Use a clothesline instead of a dryer: Drying clothes on a clothesline is more energy-efficient than using a dryer, which uses a lot of energy to generate heat.
9. Use a slow cooker instead of a stove: Slow cookers use less energy than a stove, and they can be used to make a variety of meals.
10. Plant trees and shrubs: Planting trees and shrubs around the home can reduce energy consumption by shading the home from the sun in the summer and allowing the sun to shine through in the winter
