3. IMPORTANCIA DEL AGUA
In addition to drinking water, we use it for several
daily activities, that is, we need it to cook, to wash
up, personal hygiene, watering plants and crops,
animals, in factories, energy production, and so on.
Drinking water is essential for human life,
but it’s scarce as the population increases y
that’s beacuse of ignorant and irresponsible
people.
11. MEASURES IMPLEMENTED ON
SPECIAL CASES
BATHS / SHOWERS: If we replace baths for five-minute
showers and if we turn the tap off while we’re soaping up
we willl save up to 50 l instead of the 250 l we would use
having a bath.

SPECIAL CASES
CISTERN: With a 6-litre
cisterns we can cut the water
consumption a 50 per cent if
we introduce a one-litre
plastic bottle and using a
double-flush cistern.
This could save us 3 litres in
each flush.

13. MEASURES IMPLEMENTED ON
SPECIAL CASES
HAND WASHING / TEETH BRUSHING: We spend about 20
seconds every time we wash our hands and about 40 to
50 seconds brushing our teeth. Considering that we
turned off the tap in the development of the action, the
average consumption could be of about 3 l. Thus, we
could save a 40 per cent of the water consumption.

SPECIAL CASES
WASHING MACHINE / DISH WASHER: Depending on our
consumption, we use both appliances about 1099 times a year,
with an average consumption of 55l. If we carry out full loads
with an economic and efficient programme, we can save n 18,2
per cent, decreasing the average consumption to 45l.

SPECIAL CASES
CLEANING: As a way to save water on cleaning and watering
plantes, if we use ecologic detergents for our wahings we can
reuse the water from the wastepipe. Although we can not always
do it, maybe one every two washes. This water can be used to
scrub the floor and also to water the plants since they would not
be affected by that type of detergent. With this measure we could
save up to the 37.2 %

17. ELECTRIC ENERGY CONSUMPTION
• When Thales of Miletos started
rubbing amber stones with cat’s
fur around 600 BC, he couldn’t
imagine that the static electricity
he was observing could, some
years later, transport people
from distant places in metallic
boxes we know as cars, among
many other things.
18. Our lives without electricity
• A glance around will reveal that we are so
deeply surrounded by energy that we don’t
even notice.
Energy starts up our modern lives.
• Maybe that’s the reason why we waste it so
stupidly.
24. • Central Heating: The recommended
temperature during the winter is from 22º C
to 24º C. By lowering the thermostat of our
central heating we save up to 7 % on
electricity per degree. So if we wear a
sweater instead of setting the heating to 24º
C we will save approximately 14%.
2º C
26. • Ceramic hobs:Cooking is not something we
can avoid. But the energy we waste on it
could be reduced if we used a lid. That would
mean a 25% cut on the energy we need to
prepare a tasty and efficient meal.
