Non-renewable Resources
Both
Can be replenished within a human time scale
Cannot be replaced once they have been used or require a very long geologic periods of time to replenish
Renewable Resources Vendiagram
Renewable Resources
vs
Non Renewable Resources
- Usable energy found in nature
- Both have their advantages and Disadvantages
- Low Carbon Emissions
- More Costly
- Can be replenished easily
- prevents air and water pollution
- prevents long-term negative effects
- Higher Carbon Emissions
- Lower cost Upfront
- Can't be replenished/takes too long
- contributes to global warming
How can we tell if a resource is renewable or non-renewable?
Identification of Renewable and Non-renewable resources
We can tell if a resource is renewable or non-renewable by checking how quickly it replenishes.
Renewable resources replenish reasonably quickly while non-renewable resources don't replenish or take a very long time.
How does coal cycle through the environment?
Movement of coal through the environment
The process of coal begins with plants. Once the plants die, they dont completely break down, though they still decay a bit. They are then buried by deeply sediments, which turns them into peat. Heat and pressure are applied for millions of years, which turns it into lignite. It is then pushed up to the crust where it is mined.

Diagram explaining how coal is made and how it is turned into electricity:
Using coal to produce energy can lead to a variety of different issues such as pollution and global warming.
Scientists are constantly trying to find cheaper and more efficient ways of using renewable, sustainable energy resources such as solar power.
We can help by raising awareness of the affects of using non-renewable resources so that people can make better choices.
What are scientists doing to solve dependancy on coal?
Solving Dependency on Coal
Negative Impacts:
- Raising cost of electricity bills
- Limiting energy usage
- Limiting access to energy
Impacts of resource management on society
How might resource management impact society?
Positive Impacts:
- Doesn't contribute to global warming
- Decreasing severity/occurrence of asthma and other lung diseases caused by breathing in unclean air
