8. How can we save energy?

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

8.1 Energy efficiency.
One of the best ways to save energy is to use devices that are more energy-efficient.
An energy-efficient device require less enrgy to perform the same work.
We can apply strategies of energy efficiency in many areas of daily life. In this way, we can significantly reduce the amount of energy that we consume.

• Lighting
• Domestic appliance.
• Air conditioning and heating.
• Transport.

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.

When we recycle products, we avoid the extraction and processing of more natural resources. In this way, we can save enormous amounts of energy. 

Recycling old batteries saves energy, but it is also important because batteries contain toxic materials that must be treated properly. We must never throw batteries in the batteries in the rubbish. We can also use rechargeable batteries to reduce our energy consumption.

8.3. Positive impact.

Energy efficiency has a beneficial effect on the enviroment.

When we consume less energy, it helps to reduce the greenhouse effect and climate change. It also improves people's health by reducing air and water pollution. Using less energy also reduces our explotation of natural resources.

Renewable energy sources are essential for solving our enviromental problems. In the future, most of the electricity that we use will probably come from these cleaner, greener energy sources.
