What does solar thermal energy do?
Makes electricity from sunlight
Uses sunlight to heat water
Stores sunlight in batteries
Cools down the house
Why is glycol used in solar thermal systems?
To make the water boil faster
To stop the system from freezing

What is biomass made from?
Rocks and minerals
Plant and animal materials
Metal and plastic
Water and sand
Why is biomass called a carbon neutral fuel?
It gives off no heat
It releases less smoke
It only releases the CO₂ it once absorbed
It is made from clean water
How do heat pumps work?
Like a fridge, but in reverse
Like a gas boiler
Like a solar panel
Like a fan heater
What does a ground source heat pump use to collect heat?
Solar panels
A gas burner
A coil buried underground
A fan in the roof
What do ASHPs use to make heat?
Burning wood
Solar panels
Compressing a gas
Boiling water
What happens when the refrigerant gas is compressed in an ASHP?
It turns into ice
It becomes a liquid and gives off heat
It disappears
It cools down
Where does the heat go after it’s made in an ASHP?
Into the air outside
Into the fridge
Into the heat exchanger and then the heating system
Into a battery
What does “zero carbon” mean?
The fuel gives off no heat
The fuel creates no CO₂ overall
The fuel is made from water
The fuel is used only at night
What powers a wind turbine?
Sunlight
Water
Wind
Gas
How does tidal power make electricity?
Using sunlight on water
Burning seaweed
Using moving tide water to turn turbines
Freezing ocean water
What do solar photovoltaic (PV) panels do?
Make hot water
Store heat
Make electricity from sunlight
Reflect sunlight
What is the main goal of the Energy Saving Trust?
