Science Chp 3.2

Front 1

Biogas

Back 1

a gas produced from the fermentation of
organic waste, such as waste from sugarcane, and
used as fuel

Front 2

Biomass

Back 2

all plant and animal matter found on Earth

Front 3

Fossil fuels:

Back 3

fuels such as coal, oil and natural gas,
formed from the remains of living things buried
millions of years ago

Front 4

Geothermal energy

Back 4

energy sources from heat below
the Earth’s crust

Front 5

Hydroelectricity

Back 5

the process of using water falling from
a height to turn turbines
and generate electricity

Front 6

Non-renewable energy
source:

Back 6

a source of
energy that cannot be
replaced after it is used,
such as oil or coal

Front 7

Nuclear fuel

Back 7

using
uranium or plutonium

Front 8

Renewable energy
source:

Back 8

a source of
energy that can be
replaced after it is used,
such as solar or wind
energy

Front 9

Solar cell

Back 9

a device that
absorbs solar energy and
converts it directly into
electrical energy

Front 10

Tidal barrage:

Back 10

a construction
in which water fills a basin
as a tide comes in, rotating
a turbine as it flows. The water
is stored until low tide, when it is released and again
turns the turbine. This rotation is used to generate
electricity

Front 11

Wind energy

Back 11

harnessing energy from the movement of
air using wind turbines
