2. Earth has many resources that we use
and need to save.
Earth energy is useful but it does not
last forever.
2

3. This energy has to be protected.
Energy is the ability to do work.

4. Types of energy
• Solar energy
• Wind energy
• Hydroelectric
• Geothermal energy

5. Solar energy
Solar plants are designed to make use of the
sun's energy.
5

6. Some people are already using solar energy on
its own initiative.

7. Wind power
Wind turbines producing electricity from wind energy.
Largest wind farm in the world was opened in the UK and has
100 wind turbines, enough electricity to power a city of
200,000 inhabitants.

8. Hydroelectric energy
Hydropower plants are mechanisms that use
water power to produce electricity.

9. Geothermal energy
There are three types of geothermal power plants are used
to date the globe to transform power into electricity
geothermal water: dry, flash and binary fluid depending
by state: vapor or liquid, or by temperature.

10. Using central heating people can use
and save energy and resources at the
same time. But not in all countries
there is a concern for saving energy.
10

11. Some energy saving methods:
11

12. Use fluorescent bulbs, which use much less energy
to operate and are more durable than
incandescent.
12

13. Choose your modern electronics, more efficient,
such as LCD monitors instead of CRT or change
desktop system with laptop
13

14. In the kitchen, if you have to choose between an
electric stove or microwave , choose the last one,
because it uses a third and half the energy compared
with electric stove.
14

15. Unplug all electronic devices and appliances,
when not in use, because even if they are not
running, they consume energy while stand set.
15

16. Use tumble dryers only if it is absolutely necessary.
These use up a lot of energy . If, however, you are
forced to do it, make sure the filter is clean, because air
can circulate more effectively. Of course, dry clothes
outside whenever you can.
16

17. Use air conditioners only if absolutely
necessary. Try to keep doors and windows
closed during the day and cover them with
blinds or finally curtains to block sunlight.
17

18. Outside your home install a motion sensor that
illuminates light only when it detects motion.
18

19. You will save a lot of money installing efficient
windows that capture the sun's heat in winter and
releases it in summer.

20. Today, research focuses on converting biomass
into alcohol, which could serve as fuel to
supplement or even replace gasoline and
diesel. Other liquid energy from biomass such
as vegetable oils.
