Chapter 12: Minerals and Energy
P.4: Introduction
- Non-renewable or stock resources take millions of years to form
- Such resources are for practical purposes fixed in supply= not renewable
P.6: Non-Renewable Resources in Canada: Basic Information
- Canada is a global leader in exports of minerals and metals
• Gold generated the most value from exports of metallic minerals:
$16.9 billion in 2012 and $17.7 billion in 2013
• Potash was the leader for both non-metallic and metallic minerals
P.7: Potash in Saskatchewan
• Potash = different types of potassium salts
• Discovered in 1940s during exploratory drilling for petroleum
• Potash industry developed in Saskatchewan during early 1960s and
expanded steadily during 1970s and 1980s
• 2013: Canada is 2nd largest producer of potash in the world (1st Russia)
• Estimated reserves are sufficient to meet global demand for several hundred
years (assuming current levels of use)
P.16: Energy Resources
• ER = classified as renewable and non-renewable
• Renewable resources can be replenished in a relatively short time period
• Non-renewable resources cannot be replenished over a period of time short
enough to support humans (coal, liquid fuels, natural gas, nuclear fuels)
P.17: Energy Resources [cont’d]
Energy Use and Issues in Canada: Largest consumers of energy in world
1. Germany
2. Japan
3. India
4. Russia
5. USA
6. China
7. Canada
P.: Energy Resources [cont’d]
Wind Power
• Converts kinetic energy available in wind to forms of more useful energy for
humans [mechanical energy & electricity]
o Pollution-free, sustainable form of energy that doesn’t fuel, produce
GHGs, or create toxic or radioactive waste

Document Summary
Non-renewable or stock resources take millions of years to form. Such resources are for practical purposes fixed in supply= not renewable. Canada is a global leader in exports of minerals and metals: gold generated the most value from exports of metallic minerals: . 9 billion in 2012 and . 7 billion in 2013: potash was the leader for both non-metallic and metallic minerals. Energy use and issues in canada: largest consumers of energy in world: germany, japan, india, russia, usa, china, canada. Wind power: wind turbines have minimal adverse environmental effects. Issues of health and well-being= concern for nearby residents. Solar power: renewable energy option, used for heating, cooling, electricity production, chemical processes, mostly used for heating of spaces and water. Advantages: noh harmful ghg emissions and are silent, solar energy is available almost everywhere sunlight is present, costs of solar panels are decreasing significantly.
