The document discusses energy and different types of energy sources. It defines energy as the capacity of a system to do work. It distinguishes between renewable energy sources like sunlight, wind, and rain, which are naturally replenished, and non-renewable energy sources from finite resources. It explains that renewable energy does not pollute or degrade the environment like traditional sources. The document also discusses a student group project on energies where they divided tasks and presented information on water energy and organizing their work. It provides advice for future group work and things they learned about different energy types and sources.

2. Definition of energy:
 Energy is the capacity of a system to do work. That system
may be a jet, carrying hundreds of passengers across the
ocean. A baby’s body, growing bone cells. A kite, rising on
the wind. Or a wave of light crossing a space. In moving or
growing, each of these systems is doing work, and using
energy. Every living organism does work, and needs
energy from food or photosynthesis. Humans also create
machines that do work for them, and that derive energy
from fuels.

3. Differences between renewable
energy and non-renewable
energy:
 Renewable energy is energy generated from natural resources
such as sunlight, wind, rain, tides, and geothermal heat, which
are renewable. Non-renewable energy is energy, taken from
"finite resources that will eventually dwindle, becoming too
expensive or too environmentally damaging to retrieve", as
opposed to renewable energy sources , which "are naturally
replenished in a relatively short period of time.

4. Why we need to use renewable
energy?
Its generation and use does not
contribute to the degradation of our
environment as with traditional
energy sources. Do not pollute. For
the user of the significant economic
benefits obtained. Because of
developments in technology allows
us to use systems with high
performance and low cost, thus
reaching a discounted payback
periods on investment. Because
thereby contribute to genuine
sustainable development. And for a
very simple principle, greater power
to perpetuate the legacy of our
ancestors, the environment for our
children to receive at least as we did
to our parents, and generally
contribute to a better world.

5. What is water energy?
 The water energy is the relationship between how much
water is evaporated to generate and transmit energy, and how
much energy it takes to collect, clean, move, store, and
dispose of water.

6. Organization of the group:
 We worked in group and we divided the work:
- Guillem and Jacint did “ where energy comes from “and
the design of the blogger. They choose the three games.
-Mia and Clara did the power point and the exercise of the
energies.

7. Any advice for the next group
work :
 Do the work in group
 Organized days before
 We help of the group

8. That we learned?
 have learned to work in groups
 We learned that is water energy
 We learned that the energy of the sea can do electricity
 We learned that is energy
 Differences between renewable and nonrenewable.

9. As we do to help our planet?
Here I write some things which we can do to curb climate
change:
* Say NO to plastic bags. Each year we distributed more
than 2 billion and only 3% is recycled. Try to bring your
own bag to the supermarket. Surely you will look weird
or nerdy but you contribute to saving the planet.
* No use Styrofoam cups or plates, the Styrofoam is not
recycled and is one of the biggest polluters on the planet,
it takes over 500 years to decompose. Currently there are
environmentally friendly products made ​from potato or
corn starch and can be purchased at Wal-Mart.
* Place two full bottles in the toilet box, so every time you
pull on the lever, will save 2 to 4 liters of water!...
