is clean
all of the other options
Is solar power renewable?
Yes
No
Sometimes
Only in some places
Renewable means
unlimited
polluting
that it will expire
can be reproduced
Does solar energy have any disdvantages?
Yes
No
Sometimes
Only in some places
Drawbacks of solar energy are:
it is not always available
it is polluting
it is still quite expensive
all ot the other options
Solar power for heating can be
active or passive
mechanical or non mechanical
direct or indirect
expensive or cheap
Solar power for heating is passive when
no mechanical components are used to move heat around
there is no sun (at night)
in winter
some mechanical components are used to move heat around
Solar power for heating is active when
no mechanical components are used to move heat around
some mechanical components are used to move heat around
it is very sunny and hot
it produces electricity
What are solar thermal collectors used for?
To produce electricity
To heat water or homes
To produce electricity and warm up water and homes
Neither of the other options
This is
a solar thermal collector
a photovoltaic panel
a concentrating collector
the roof of a house
Concentrating collectors
are panels that produce electricity
are solar panels that use mirrors or lenses
are flat
have photovoltaic cells
Solar panels may have tanks
True
False
In solar thermal collectors water
is concentrated in a tank
passes in tubes right under the surface
all false
can be cooled down
Where are solar panels usually located?
On the groud near a building
Directed north
On the roof - directed south
In large sunny areas
Where are concentrating panels usually located?
On the roofs
In large sunny areas
Underground
In small areas in the shadow
What does a photovoltaic panel produce?
Heat
Thermal energy
Electricity
Mechanical energy
What does a photovoltaic panel consist of?
Solar cells
Electrons
A system of tubes
Photons
This is
a flat solar panel
a photovoltaic panel
a photovoltaic cell
a system for heating water
How do solar cells use produce electricity?
Converting heat
Thanks to the movement of electrons inside the cells
Using thermal energy
Transforming photons into electrons
These are
Photovoltaic panels
Thermal collectors
Concentrating collectors
Satellite dishes
What is a ClimateHouse?
A style
An energy category
A house combining energy saving and healthy living
A modern luxurious house
A ClimateHouse is designed to
save energy
contribute to environmental protection and help against global warming
increase wellbeing
all of the other options
ClimateHouses are divided into
different classes
different styles
four categories
modern or old
Houses can be classified ClimateHouses
Gold, Silver and Bronze
Gold, A and B
From A to G
From A to Z
A thermal bridge
is a bridge exposed to heat extremes
is a defect in thermal insulation
is typical of a ClimateHouse
all options correct
Which of the following is NOT a characteristic of a ClimateHouse?
compact structure and thermal isulation of walls and windows
tightness and absence of thermal bridges
use of electricity and fossil fuels
use of solar energy
accurate realization and optimal plant engineering
ClimateHouse+ combines
living comfort, high energy consume and ecological construction techniques
living comfort, high energy saving and ecological construction techniques
ecological materials and use of renewable resources
new materials derived from plastic
Wind power is
the energy of the wind
always available
is used to produce electricity
produces absolutely no pollution
What device do you need to convert the energy of the wind into electricity?
Wind turbines
Propellers
Wind mills
The sun
Do wind turbines need a propeller?
Yes
No
Sometimes
What is a wind farm?
A farm that uses windpower
Wind turbines grouped together in an area
A plant that produces energy to move wind turbines
A farm that produces wind
What type of energy does a wind farm exploit?
Electricity
Mechancal energy
Thermal energy
All otpions correct
The basic elements of wind turbines are:
blades, shafts, gears and generators
towers
blades
gears and blades
A = shaft, B = gear, C = generator,
D = wind, E = blades
A = gears, B = shaft, C = blades,
D = wind, E = generator
A = generator, B = gear, C = shaft,
D = wind, E = blades
A = shaft, B = gear, C = generator,
D = water, E = blades
