Name the Energy Source:

Ørenewable

Ø heating and cooking

Ø 1.5 billion people use this energy source

Ø mostly in developing countries

Ø the most ancient form of fuel!

Ø harvesting (collecting from nature)

Name the Energy Source:

Ørenewable

Ø decaying plant matter in bogs

Ø heating

Ø It is dried first

Ø mostly in Ireland, England, N. Europe

Ø also an ancient form of fuel!

harvesting (collecting from nature)

Name the Energy Source:

Ø nonrenewable

Ø fossilized swampy plants

Ø electricity production

Ø burned to heat water to spin the turbines of a generator

Ø USA has more coal than the world has oil!

Ø burning causes air pollution

mining (surface pit or underground)

Name the Energy Source:

Ønonrenewable

Ø fossilized plankton

Ø refined for gasoline, mostly

Ø found in porous sedimentary rocks similar to how groundwater is stored

Ø a mixture of hydrocarbons (H and C)

Ø drilling - oil derricks (land) / oil rigs (offshore)

What are the ways we obtain energy from the environment?

Name the Energy Source:

Ø nonrenewable

Ø sandstone

Ø electricity production

Ø nuclear FISSION produces heat to boil water to spin turbines

Ø about 100 nuclear power plants in USA

Ø produces no carbon emissions but …

produces nuclear waste

Name the Energy Source:

turbines spin with the motion of rising and falling water, producing electricity.

}energy produces electricity when “Earth’s heat” turns water to steam to spin turbines

}It can also heat water and homes.
