Sustainability
Sustainable vs Unsustainable Energy Resources
What is sustainability?
- using only an amount of our resources we require today so that future generations wouldn't have to compromise to meet their needs
- should be able to be maintained for it to be considered sustainable
Most sustainable energy sources
Hydro-Electricity:
- uses fast flowing water that falls a great distance and harvesting its energy with a dam
- is naturally replenished; once its built it is an infinite energy source and is much safer compared to other energy sources
Solar:
- converts the light we get from the sun into energy by the use of solar panels
- the use of solar energy had been universally accessible and flexible
Wind Energy:
- wind turbines are used to produce electricity by converting the kinetic energy in the wind
- it does not pollute air when used, is a domestic source of energy, and is cheap
Environmental impacts of oil sands
- releases large amounts of greenhouse gases
- deforestation to get to the oil
- uses vast amounts of fresh water
- animal habitats are destroyed

What are some ways we can reduce the amount of energy we use in our day to day lives?
Air Conditioning
Use a fan instead of air conditioning during the summer.
Light
Use a timer to reduce the amount of energy used to light your home.
Kitchen
Cook foods together that require the same oven temperature. Limit pre-heating your oven.
