How to reduce wasted energy

Here are two general ways to reduce wasted energy:

• Insulation: Using insulating materials can reduce heat loss to the surroundings, keeping energy contained within the system where it is needed. For example, insulating a hot water tank or a house reduces the energy wasted as heat escaping.
• Maintenance and design improvements: Regularly maintaining appliances (like descaling a kettle) or designing systems with more efficient components (like using LED lights instead of incandescent bulbs) can minimize energy conversion losses.
