Non-Renewable Energies.

Non-renewable energy is energy from fossil fuels (coal, crude oil, natural gas) and uranium. Fossil fuels are mainly made up of Carbon. It is believed that fossil fuels were formed over 300 million years ago, when the earth was a lot different in its landscape. It had swampy forests and very shallow seas. This time is referred to as 'Carboniferous Period'

Fossil fuels are formed....

1. Millions of years ago, dead sea organisms, plants and animals settled on the ocean floor and in the porous rocks.
2. With time, sand, sediments and impermeable rock settled on the organic matter, trapping its' energy within the porous rocks.
3. Earth movements and rock shifts creates spaces that force to collect these energy types into well-defined areas.

• Advantages:
• Unlike many renewable sources of energy, fossil fuels are relatively less expensive to produce.
• Issues:
• Fossil fuels are made up mainly of carbon. When they are burned (used) they produce a lot of carbon compounds (carbon dioxide and other greenhouse gases) that hurt the environment in many ways.
• In the pages that follow, we shall take a look at what each source of non-renewable energy is made of, and how they are used.
