8. HOW CAN WE SAVE ENERGY?

There are two important ways we can save energy: by increasing the energy efficiency of the devices that we use and by recycling as much as possible.

8.1. Energy efficiency.

An energy-efficient device requires less energy to perform the same work.

• Lighting: We can reduce the amount of electric light that we use by taking advantage of natural lighting.
• Domestic appliances: New appliances have energy efficiency labels to indicate how much energy they consume.
• Air conditioning and heating: We use a lot of energy to keep our homes at a comfortable temperature, but there are ways we can be more efficient.
• Transport: The best way to consume less energy is to use public transport or to travel with other people when going long distances.

8.2.. Recycling.

Our consumption of manufactured products generates waste and uses energy. We can reduce these negative effects by recycling as much as possible.

8.3. Positive impact.

Energy efficiency has a beneficial effect on the environment.
There are various projects to develop clean energy, such as nuclear fusion, which is the source of our Sun's energy.
