Unit 7. Saving energy

Solar energy is energy from the sun.
Solar energy is renewable energy source.
Solar energy is very reliable energy source.
Solar energy free and clean energy source.

Solar energy doesn`t produce no waste or pollution and is ecologically acceptable.

Solar energy drives climate and weather and supports all life on Earth.
Solar energy is used in many applications like: Electricity, Evaporation, Biomass, Heating water and buildings and even for transport (solar cars).


Solar energy`s use should be gradually growing in years to come.

Solar energy could generate 2.5 percent of the world`s electricity by 2025.

Solar energy has tremendous potential because for instance the energy we get from all of the world`s reserves of coal, oil and natural gas can be matched by just 20 days` supply of sunshine.

Solar energy will be more affordable in future with new scientific researches that should decrease the costs and increase the efficiency of the solar energy.

Solar energy should be used not only to decrease the use of fossil fuels but also to decrease the price of fossil fuels.




The use of solar energy to produce electricity allows the user to become less dependent on the worlds fossil fuel supplies
Solar energy could improve environmental quality that is damaged by current dominant fossil fuels use.

The production of energy from the use of fossil and some renewable fuels (e.g. wind turbines) can be noisy, yet solar energy produces electricity very quietly.

By using solar energy help to saving lots of energy
