Non Renewable Energy Review Topics
Energy and Resources
What is a resource?
A resource is something that can be used for a specific purpose or need.
How are resources distributed?
Unevenly
What does it mean to be non renewable?
It means that it cannot be replaced quickly after it is used up
What are Energy Resources?
Natural resources or materials that come from the environment to produce energy used for heat
What is Fossil Fuel?
An energy that came from dead animals and plants buried underground for millions of years
What do we use Energy resources for?
Electricity, heat and cooling, and transportation
How do we convert energy into electricity? Know the steps
The energy source is burned
Water is heated to produce steam
Steam turns a turbine
Turbine moves the generator
Energy is created
Fossil Fuels
How do fossil fuels form?
plants and animals die
Remains get berries by sediment
Heat and pressure builds up
Coal - How does it form?
Forms from decaying remains of plant materials in swamps
Organic materials fall to the ground and sediment covers it. With pressure, heat, and time, the organic material is compacted.
4 Grades of Coal - Know how each forms and what makes each different
anthracite , lignite, bituminous, peat
A= hardest, cleanest-burning type of coal.
L= softest and lowest-quality type of coal. It’s also called brown coal because of its color.
B=
P=
Mining for Coal
Surface/Strip, Subsurface, MountainTop Removal
Environmental Impacts of Mining and Burning Coal
Contributes to climate change, habitat loss, air and water pollution
Human Health Impacts from Burning Coal
Respiratory + cardiovascular problems, cancer, etc.
Oil- How does it form?
Forms from the decay of marine life that accumulated to the ocean floor millions of years ago
Crude Oil - What is it?
A raw natural resource that is extracted from the ground before being processed into products like gasoline, diesel, plastics.
How do we mine for Oil
Drilling
Environmental Impacts of Mining and Burning Oil
Air Pollution
Water pollution
Habitat destruction
Acid rain
Human Health Impacts from Burning Oil
Asthma
Heart attacks
cancer
Natural Gas - How does it form?
Sea animals die
Buried underground
Heat and pressure build up
Gas gets trapped
Natural Gas - What is it?
A clean fossil fuel found deep underground
Mining for NG
Drilling and Fracking
Environmental Impacts of Mining and Burning NG
Habitat damage
Water and air pollution
Human Health Impacts from Burning NG
Carbon monoxide risk
Heart disease
Lung problems
Nuclear
Why is Nuclear not a fossil fuel?
Because it doesn't come from plants or animals
How is energy converted from Uranium 235 to electricity?
Nuclear fission
Water is heated
Steam spins a turbine
Turbine turns the generator
Electricity is created
What are the Environmental Impacts of Mining and Converting U235 into Electricity
Water pollution
Radioactive dust
air pollution
Human Health Impacts from Nuclear Power
Cancer
Radiation sickness
Nuclear Accidents
Chernobyl (1986 – Ukraine)
Fukushima (2011 – Japan)
Three Mile Island (1979 – USA)
