Impact On Sustainability Flashcards
What are finite resources ?
Non renewable and will eventually run out
What are finite resources ?
Resources that can only be used once and is in limited supply meaning it will eventually run out
What are some examples of finite resources ?
- metals
- plastics
- fossil fuels Eg coal, natural gas and oil
Why are finite resources popular ?
Easily accessible due to strong supply chains and often have benefits for manufacturing particular products or for energy supplies
What have companies now decided to do with finite resources ?
Become more careful in their usage of finite resources and consider ecological footprint
What is ecological footprint ?
An analytical measurement of the amount of global resources used
What are no finite resources ?
Found naturally and can be replaced
A renewable energy that harness the earth natural resources
What are some examples of non finite resources ?
Wood
Cotton
Renewable energy Eg solar and wind
What are both non renewable energy and renewable energy used for ?
To generate lighting, power electronics, heat homes and more
What are the five different renewable energy sources ?
Solid
Wind
Biomass
Water
Geothermal
What is solar energy and give 1 advantage and disadvantage to it
Solar- uses sunlight to generate energy through solar cells
Advantage- huge free sources of energy to create power
Disadvantages- the panels can be expensive initially, less sunlight in winter months
What is wind energy and give 1 advantage and disadvantage to it
Wind- uses the wind to generate energy through wind turbines
Advantage- does not pollute air
Disadvantage- expensive set up costs, some people dislike their appereance and can be noisy
What is biomass energy and what is 1 advantage and disadvantage to it ?
Biomass- uses organic materials to generate energy through burning to create gases
Advantage- good use of waste crops
Disadvantages- crops need to be available, burning them can pollute the air
What is water energy and give 1 advantage and disadvantage to it
Water- uses falling water to generate energy through turning water mills
Advantage- clean fuel source
Disadvantage- can affect the flow of water and costly to initially set up
What is geothermal energy and give 1 advantage and disadvantage to it
Geothermal- uses heat from deep underground to generate energy
Advantage- no harmful gases
Disadvantage- to operate the pumps electricity is still needed
