UNIT 3 – ENERGY AND POWERTopic 1: Energy Sources – Power Plants and Fuels FUEL: a material used to produce heat or power
Most of the following are power plants – what is the fuel shown/used in each image?
IOT

The Sun is the source of all energy on Earth.
Topic 1
Energy Sources – FuelsWhat is the source of all energy on
earth?
IOT

1. Energy is NOT fuel used for transportation and heating, for lights and appliances, and foods for consumption.
FUEL ENERGY2. Fuels are a source of energy.3. Fuels are the material source of energy,
containing it as a potential.
Fuels and Energy – What is the difference?

1. Fossil fuels are burned to release stored energy.2. Formed from the heated and pressurized
remains of dead plant and animal life over hundreds of millions of years.
3. Non-renewable – millions of years to form and reserves are being depleted faster than new ones are being formed.
4. Volatile: natural gas and petroleum5. Nonvolatile: coal
THE FACTS: Non-Renewable Fuels – Fossil Fuels
IOT

Non-Renewable Fuels – Coal1. Coal is formed from the remains of terrestrial
plants that died around 350 million years ago. 2. Plant remains preserved in water and mud.

Non-Renewable Fuels – Coal
History of Extraction and Use• Colliery (COLL-yer-ee) – a coal mine and its
connected buildings.Coal must be cleaned and refined (improved) after
extraction• South Wales, Great Britain – oldest known colliery.• First commercial coal mining in U.S. in 1730s, VA.• Prior to 1880s, coal was picked by hand
underground.• By 1912, surface mining was used.

Non-Renewable Fuels – Coal
(2) Methods of ExtractionUnderground Mining:
• 60% of world production• 33% of U.S. mining• Uses timber for support tunnel• Machines enter and extract coal
Surface (Strip) Mining:• More coal extracted than underground mining• Exposes coal by removing land above deposits

Non-Renewable Fuels – Coal
Uses• Coal is mostly used as a solid fuel to produce
electricity and heat through combustion.• It is usually pulverized (crushed into small
particles) then burned in a furnace for electricity generation at a power plant.
• ~40% of world’s electricity comes from coal• ~49% of U.S. electricity comes from coal
