1 Energy sources
-
Household uses: : the operating of electncal appliances, heating systems, hot water systems, heat for cool.ing and for means of systems, hot water systems, heat for cooling and for means transport, for example.
Energy sources are natural resources from which we obtain different forms of energy that can be transformed for a specific use
Industrial uses: : the operating of factones and companies, construction, agnculture and so on

4.5. Ocean power plants
-
These power plants use the energy from the seas and the oceans. The concept is to use three types of energy from the sea.
The mechanical energy from the tides.
The mechanical energy from the waves
The energy from the ocean's thermal gradient.

Electricity generation
-
-
They produce air pollution — suspended particles, CO, heavy metal molecules and so on.
They emit large amounts of COa which increases rhe greenhouse effect. They emit sulphur dioxide and nitrogen oxide that cause acid rain, which is very harmful to the environment.
Nuclear thermal power plants are accompanied by the nsk of
nuclear accidents and the problem of nuclear waste, some of which remam dangerous for thousands of years
5.3. Waste treatment
-
-
Use coal with a low sulphur content, to reduce acid ram.
Ma intain and increase the size of large forested areas, since they s absorb carbon dioxide
Photovoltaic power plant
-
There are also isolated power plants that are very small in size, which are used to supply electricity to home in rural areas.
-
-
Fuel transport
-
-
Oil pipehnes can suffer accidents caused by nature or human error, which result in uncontrolled spills.
-
Final energy use
-
Thc fuels we use in vehicles and heating systems emit gases and
part«.les similar to those generated by convenuonal thermal power plants.
