Where we get itHow we use itHow our use of energy sources affects our lives

Energy

Created for my energetic students

Energy is the ability to cause changes, exert forces or do work.

(In other words, energy is the ability to make things happen!)

What is energy?

Non-renewable energy sources will some day be gone.◦Coal

Petroleum Natural Gas

Old types of energy

HOW LONG WILL THESE FUELS LAST?

Renewable energy sources is a natural resource that can be replaced in a reasonable amount of time.

Non-renewable energy resource

Is a resource that is unable to be replaced naturally or is replaced very slowly

Non-renewable vs Renewable

Energy is released as heat and light when coal burns.

Energy can exist in many forms. It can be stored or expressed actively.

Fossil fuels include peat, coal, oil, and natural gas.

Fossil fuel is any fuel formed deep in Earth’s crust from the remains of plants and animals.

Fossil fuels are, oil, natural gas, and coal. Peat is not as old, but is a fossil fuel, too.

There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – hence the name fossil fuels. At some point, the supply of fossil fuels will be gone, and humans must use other, cleaner, and renewable sources for energy to power our factories, homes, cars and so on.

Oil, also called petroleum, is found in many places throughout the world.

Some oil rigs are on land. Wells may go down very deep to get to a pool of oil.

Offshore oil platform

An oil platform, (offshore platform or colloquially oil rig) is a large structure with facilities to drill wells, to extract and process oil and natural gas, and to temporarily store product until it can be brought to shore for refining and marketing. In many cases, the platform contains facilities to house the workforce as well.Depending on the circumstances, the platform may be fixed to the ocean floor, may consist of an artificial island, or may float. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These subsea solutions may consist of one or more subsea wells, or of one or more manifold centers for multiple wells.

Workers live on the oil rig three or four weeks at a time.

Workers live on the platform for several weeks, then go home for a week or two, and come back again to work.

The nature of their operation — extraction of volatile substances sometimes under extreme pressure in a hostile environment — means risk; accidents and tragedies occur regularly. The U.S. Minerals Management Service reported 69 offshore deaths, 1,349 injuries, and 858 fires and explosions on offshore rigs in the Gulf of Mexico from 2001 to 2010.[14] In July 1988, 167 people died when Occidental Petroleum's Piper Alpha offshore production platform, on the Piper field in the UK sector of the North Sea, exploded after a gas leak.
