Energy Basics
We need this to be able to move our bodies, do work, play sports or games, and for our bodies to function.
What is energy?
Wind and solar power are examples of this type of energy resource.
What are renewable resources?
Using wind to move a sailboat is an example of this type of energy use.
What is direct energy use?
A push or a pull is called this.
What is a "force"?
This gas increases when fossil fuels are burned and contributes to climate change.
What are greenhouse gases?
We need this type of energy from food so our bodies can move, play, and learn.
What is chemical energy?
Oil, coal, and natural gas belong to this group because they will run out.
What are nonrenewable resources?
Solar panels creating electricity are an example of this type of energy use.
What is processed energy use?
Wind turbines work because moving air applies this force to the blades.
What is force from motion (wind force)?
These toxic ponds are created during oil extraction and must be carefully managed.
What are tailings ponds?
This form of energy powers lights, TVs, and video game consoles.
What is electrical energy?
This renewable resource uses moving water to spin turbines and create electricity.
What is hydroelectric energy?
This energy resource can be used both directly and after processing.
What is wood? (also acceptable: water or solar)
Turbines spin because moving water or air transfers energy through motion. This energy is called ___.
What is kinetic energy?
The process of returning land to a natural state after mining is called ___.
What is reclamation?
Energy that keeps our homes warm in the winter is mainly this type.
What is thermal (heat) energy?
This nonrenewable resource is commonly used to heat homes and generate electricity in Alberta.
What is natural gas?
Oil must be refined before it can fuel cars. This means it is a ___ energy resource.
What is processed?
This happens when energy from wind or water causes an object to change speed or direction.
What is motion caused by force?
One reason Alberta used coal for so long was because it was easy to access and ___.
What is readily available / efficient / affordable?
Energy cannot be created or destroyed, only changed from one form to another. This idea is called a ___.
What is energy conversion (or conservation of energy)?
This is one major reason governments are increasing the use of renewable energy.
What is to reduce greenhouse gas emissions / reduce climate change?
Energy resources are processed most often to make this usable form of energy.
What is electricity?
In hydroelectric dams, flowing water applies force to turbines, changing energy into ___.
What is electrical energy?
Alberta is moving away from coal mainly to reduce emissions and increase ___.
What are renewable energy sources?
