[1]QUESTIONS about SOLAR ENERGY
Using your own words, explain how the three
kinds of hydrocarbures are formed.
The sunlight reaches the Earth and ...
1.- Tyny plants floting in the ocean trap sunlight. They
store the energy inside them,
1.1.- The plants die and get buried under sediment .
Over millions of years they break down to form gas.
Energy that was stored in the plants is now stored in
the gas. We pipe the gas out and burn it. The energy is
released as heat for cooking, and warming our homes.
1.2.- Sea creatures feed on the pants, and take in the
stored energy. They die and get burried under
sediment, Over millions of years, their soft parts turn to
oil. Energy that was stored in their bodies is now stored
in the oil. We pump out oil and turn some into petrol.
We burn this in car engines. The energy is released and
make cars move.
2.- Trees and bushes also trap sunlight. They store the
energy in their wood. In many countries people burn
wood as firewood. The energy is released as heat for
cooking food.
3.- Meanwhile on land pants in warm steamy swamps
trap sunlight. The plants die. They get buried under
sediment. Over millions of years they turn into coal.
Energy that was stored in the plants is now stored in the
coal. We dig up coal and burn it. The energy is released
as heat for factories and homes.

Explain, using simple drawings, how electricity
can be produced. Search in the Internet and find
which is the nearest power station in your
country to produce energy from coal. It would be
great if you find a map with all the power
stations.
1º We boil the water to produce steam. We heat the
water by burning fuel – oil, gas, coal, wood, or even
rubbish!
Or using the heat given out by nuclear fuel.
2º The jet of steam makes the turbine spin.
3º Next to the turbine is a generator. It contains the
electromagnet and coil.
4º When the turbine spins, it does the electromagnet
to rotate and it produces the electricity.
5º Cables carry it away to homes, schools, offices
and factories

[1] QUESTIONS about SOLAR ENERGY
There are two kinds of gasses. The first one is carbon
dioxide and the second is sulphur dioxide and nitrogen
oxides. What effect do they produce in our
environment? which kind of energy shown in the table
is less dangerous for our environment? And which is
the most dangerous?
Carbon dioxide helps trapping heat from the sun in our
atmosphere. Without carbon the Earth would be cold. But it
emissions are one of the main causes of global warming.
Sulphur dioxide can result in breathing problems with asthmatic
children and adults who are active outdoors.
Nitrogen oxides helps form acid rain and it's contributes to global
warming.
Carbon dioxide is less dangerous for our environment. Nitrogen
oxides is the most dangerous kind of energy.

Give some solutions to global warming
1.- Replace a regular incandescent light bulb with a compact
fluorescent light bulb.
2.- Install a programmable thermostat.
3.- Choose energy efficient appliances when making new
purchases.
4.- Don't leave appliances on standby, use the "on/off" function on
the machine itself.
5.- Don't let heat escape from your house over a long period.
6.- Using renewable sources like waves, tides, solar , biomass or
wind.

[1] QUESTIONS about SOLAR ENERGY
What can PV cells be used for?
If you want to know more …
Photovoltaic cells are devices that produce electricity directly
from sunlight.
http://www.kidzworld.com/articl
e/1288-solar-energy
Photovoltaic cells convert light into electricity.
One of the most important parts of a photovoltaic cell is the
material used as the semiconductor.
The PV cells (photovoltaic cells) can be used to give
electricity to a lot of devices, for example a fridge, a phone, a
TV, a farm, etc.
What does Passive Solar Architecture talk about?
Passive Solar Architecture is dedicated to modeling, the
selection and proper use of solar technology. This keeps the
environment of a home at a comfortable temperature by
means of sun every day of the year. Because it reduces the
active solar technology, renewable energies and especially
the fossil fuel technologies.

[1] QUESTIONS about SOLAR ENERGY
What's the best orientation for a house? North,
south west or east? And explain why.
In places like ours, in the south of Spain, we have a lot hours
per year with sun. The north face is usually the coldest one
and the east or west side can be too much warm in the
mornig or evening, during the sunrise and sunset.
The south face of the house is the best. During the summer
when the sun is very high the solar rays fall down almost
perpendicular to the earth, so we can have shadow inside the
house, but in winter the solar rays are more horizontal, so
they come inside the house through the south face and warm
it.
Which are the most efficient materials that you
should use in each kind of weather for windows,
walls and roofs?
The most efficient materials are:
* Synthetic polymers: polystyrene, polyethylene, polyurethane,
polyisocyanurate.
* Aerogel.
* Mineral wool, glass fiber, rock wool, slag.
* Minerals: Vermiculite, Perlite.
* Natural plant materials: cellulose insulation, cork, hemp, cotton,
straw.
* Animal fibers: wool.
* Natural plant materials: corn cobs, straw dust, wood shavings,
sawdust, bark, redwood, fir fiber or balsa wood.* Plates.
* Fiberglass.
* Granules.
* Spray foams
* Rigid panels.
* Structured and special groups.
* Bales of straw.

[1] QUESTIONS about SOLAR ENERGY
How can you use the Architecture elements in a
house to take the most of the solar rays and
shadows in a house?
We can harness the sun's rays to guide the windows to the
sun, making them bigger, using rooftops and attics, making
more room on the terraces and gardens to put solar panels
have holes in the upper parts of buildings to place solar
panels,...
We can also take advantage of some outdoor ceiling so you
have to shade porches, awnings and pergolas placed on
patios, terraces, gardens or other places abroad or in the sun.
How can we use solar power energy in a house to
produce hot water or electricity
- Hot water: The solar panels can be used with, connected to
tubes that carry a liquid that heats the water that reaches a
water tank. This distributes the water tank pipes inside the
house at different points on this.
- Electricity: We can also use photovoltaic panels through
which convert sunlight directly into electricity. The sun's rays
reach the panels, to the cells, which contain photovoltaic
cells. This process converts the rays into electricity.
