|
Is the world running out of energy?
|
No. Nuclear and solar energy are each adequate for the next billion years
|
|
|
|
Why are fuels useful?
|
fuels are substances that burn to release energy
|
|
|
|
Name a renewable energy resource
|
wind, waves, running water, sunlight, biomass, geothermal
|
|
|
|
What is energy?
|
Energy is the capacity to do work.
|
|
|
|
How do animals get energy?
|
Our energy comes from food.
|
|
|
|
List 3 other forms of energy
|
Light, water, oil or gas, nuclear, solar or wind, sound, heat, or electricity
|
|
|
|
Look on this picture and list 2 forms of energy
|
solar, wind, biomass
|
|
|
|
What is kinetic energy?
|
"Movement energy" is called kinetic energy. Objects that move have kinetic energy
|
|
|
|
What is potential energy?
|

|
|
|
|
Look on this picture and list 3 forms of energy
|
solar, wind, water, biomass
|
|
|
|
Look on this picture and say what it is
|
a power station
|
|
|
|

|
A power station
|
|
|
|
When you turn on a light, you are converting what _________energy to ________ and _________energy
|
electrical energy into heat and light energy
|
|
|
|
What Is Renewable Energy?
|
Energy that doesn't run out
|
|
|
|
Why is Renewable energy also called “clean energy” or “green power”
|
because it doesn’t pollute the air or the water
|
|
|
|
Why don’t we use renewable energy all the time?
|
Unlike natural gas and coal, we can’t store up wind and sunshine to use whenever we need to make more electricity. If the wind doesn’t blow or the sun hides behind clouds, then we cannot make the energy.
|
|
|
|
Where does most of the energy on Earth come from (originally)
|
from the Sun
|
|
|
|
What is energy from the sun called?
|
Solar energy
|
|
|
|
How do plants use energy?
|
light is needed for photosynthesis. The energy source of green plants is light
|
|
|
|
When is solar power not made?
|
at night
|
|
|
|
Look at this picture and say what form of energy
|
solar
|
|
|
|
Where does Hydro-electric energy comes from?
|
water
|
|
|
|
How does hydro-electric energy work
|
electricity is created from the potential energy stored in water by dams. These dams hold back water creating a height difference
|
potential energy, gravity
|
|
|
Hydroelectric power uses what for energy?
|
Running water
|
|
|
|
Look at this picture and say what form of energy

|
water
|
|
|
What kind of energy comes from a volcano or a geyser?
|
geothermal energy
|
|
|
|
Look at this picture and say what form of energy
|
Geothermal
|
|
|
|
What does “Geo” or “Thermal” mean?
|
"Geo" means "from the earth," and "thermal" means "heat," so this type of energy is found under the earth.
|
hot lava
|
|
|
Give an example of Geothermal energy
|
The hot lava from a volcano and the hot steam from a geyser both come from underground heat
|
"Geo" means earth, and "thermal" means heat
|
|
|
List 3 fossil fuels
|
oil, petrol, natural gas and coal
|
|
|
|
Why are they called fossil fuels?
|
They were formed millions of years ago from the remains of plants and animals. Formed deep in the earth during dinosaur times.
|
dinosaur times
|
|
|
Are fossil fuels renewable or non-renewable?
|
non-renewable
|
|
|
|
Why are fossil fuels non-renewable?
|
Since it took millions of years to create these fossil fuels, the problem is that fossil fuels can't be replaced.
|
|
|
|
What does non-renewable energy source mean?
|
Energy sources that are used up faster than they are being created.
