  • 3rd side (hint)
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?
Potential energy is stored energy. An apple sitting on the edge of a table has stored 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
Where is electricity made?
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
Hydroelectric
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.
Look at this picture and say what form of energy
Fossil Fuels, (accept) oil, petrol, gas, coal
List a problem with burning fossil fuels?
A problem of burning fossil fuels is that it causes pollution
What is the major concern about nuclear energy?
The waste is harmful to people and must be carefully disposed of for safety reasons
Look at this picture and say what form of energy
Nuclear energy
Are wind generators renewable or non-renewable energy?
renewable energy
Another name for a windmill is a what?
Wind turbine
Look at this picture and say what form of energy
wind energy
What kind of energy comes from the campfire or fireplace?
biomass energy
What does Biomass energy mean? What is Biomass?
"natural material" like trees and plants or waste products like trash
Look at this picture and say what form of energy
Biomass energy
Landfill energy comes from where?
Rubbish dumps
Give one example of biomass energy
wood, crops, garbage
Look at this picture and say what form of energy
Fossil Fuels, (accept) oil, petrol, gas
List a problem with burning fossil fuels?
A problem of burning fossil fuels is that it causes pollution
What is the major concern about nuclear energy?
The waste is harmful to people and must be carefully disposed of for safety reasons
Look at this picture and say what form of energy
Nuclear energy
Are wind generators renewable or non-renewable energy?
renewable energy
Another name for a windmill is a what?
Wind turbine
Look at this picture and say what form of energy
wind energy
What kind of energy comes from the campfire or fireplace?
biomass energy
What does Biomass energy mean? What is Biomass?
"natural material" like trees and plants or waste products like trash
Look at this picture and say what form of energy
Biomass energy
Is wind energy renewable or non-renewable?
renewable
Is hydro-electric energy renewable or non-renewable?
