NonrenewableNonrenewable Basics Basics

Non-renewable energy sources Non-renewable energy sources come out of thecome out of the ground ground as liquids, gases, and solids.as liquids, gases, and solids.

Crude oil (Crude oil (petroleumpetroleum) is the only commercial nonrenewable ) is the only commercial nonrenewable fuel that is naturally in fuel that is naturally in liquid formliquid form..

Natural gasNatural gas and propane are normally and propane are normally gasesgases,, and and coalcoal is a is a solid.solid.

Oil & Natural GasOil & Natural Gas

OilOil was formed from the remains of animals and was formed from the remains of animals and plants that lived millions of years ago in a plants that lived millions of years ago in a marinemarine (water) (water) environmentenvironment before the dinosaurs. before the dinosaurs.

Over millions of years, the remains of these Over millions of years, the remains of these animals and plants were covered by layers of animals and plants were covered by layers of sand and silt. sand and silt.

The main ingredient in The main ingredient in natural gasnatural gas is methane (a is methane (a compound gas) compound gas)

Millions of years ago, the remains of plants and Millions of years ago, the remains of plants and animals decayed and built up in thick layers.  This animals decayed and built up in thick layers.  This decayed matter from plants and animals is called decayed matter from plants and animals is called organic materialorganic material — it was once alive.  — it was once alive. 

Pressure and heat changed some of this organic Pressure and heat changed some of this organic material into material into coalcoal, some into oil (, some into oil (petroleumpetroleum), and ), and some into some into natural gasnatural gas — tiny bubbles of odorless — tiny bubbles of odorless gas. gas.

CoalCoal

Coal Takes Millions of Years To CreateCoal Takes Millions of Years To Create

• Coal is a combustible black or brownish-black Coal is a combustible black or brownish-black sedimentary rock composed mostly of carbon sedimentary rock composed mostly of carbon and hydrocarbons and hydrocarbons

Coal is a non-renewable energy source because Coal is a non-renewable energy source because it takes millions of years to create. it takes millions of years to create. The energy in coal comes from the energy stored The energy in coal comes from the energy stored by plants that lived hundreds of millions of years by plants that lived hundreds of millions of years ago, when the Earth was partly covered ago, when the Earth was partly covered with swampy forests. with swampy forests.

Nuclear EnergyNuclear Energy Nuclear energy is energy in the nucleus (core) of an Nuclear energy is energy in the nucleus (core) of an

atom.It is energy from atoms. Atoms are tiny particles atom.It is energy from atoms. Atoms are tiny particles that make up every object in the universe. that make up every object in the universe.

Nuclear energy can be used to make electricity. But first Nuclear energy can be used to make electricity. But first the energy must be released. the energy must be released.

Renewable BasicsRenewable Basics: :

Renewable energy sources can be Renewable energy sources can be replenished in a short period of time. The replenished in a short period of time. The five renewable sources used most often five renewable sources used most often are :are :

BiomassBiomass Biomass is Biomass is organic materialorganic material made from plants and animals. made from plants and animals.

Biomass contains stored energy from the sun.Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called Plants absorb the sun's energy in a process called

photosynthesis. The chemical energy in plants gets passed photosynthesis. The chemical energy in plants gets passed

GeothermalGeothermal The word The word geothermalgeothermal comes from the Greek words comes from the Greek words geogeo

((earthearth) and ) and thermetherme ( (heatheat). So, geothermal energy is heat ). So, geothermal energy is heat from within the Earth. We can recover this heat as steam or from within the Earth. We can recover this heat as steam or hot water and use it to heat buildings or generate hot water and use it to heat buildings or generate electricity. electricity.

Geothermal energy is a Geothermal energy is a renewablerenewable energy source because energy source because the heat is continuously produced inside the Earth.the heat is continuously produced inside the Earth.

Wind, energy from moving airWind, energy from moving air

WindWind is simply air in motion. It is caused by the is simply air in motion. It is caused by the uneven heating of the Earth's surface by the uneven heating of the Earth's surface by the sun. Because the Earth's surface is made of sun. Because the Earth's surface is made of very different types of land and water, it absorbs very different types of land and water, it absorbs the sun's heat at different rates.the sun's heat at different rates.

Energy from the SunEnergy from the Sun

The The sunsun has produced energy for billions of years.  Solar has produced energy for billions of years.  Solar energy is the sun’s rays (solar radiation) that reach the energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of Earth. This energy can be converted into other forms of energy, such as energy, such as heat and electricityheat and electricity..

Radiant energy from the sun has powered life on Earth for Radiant energy from the sun has powered life on Earth for many millions of years.many millions of years.
