Conventional resources

‘’Conventional Sources Of Energy ’’

‘‘Traditional sources of energy’’

WHAT ARE CONVENTIONAL RESOURCES

Energy that has been used from ancient times is known as conventional energy. Coal, natural gas, oil, and firewood are examples of conventional energy sources.

THE REMAINS OF PREHISTORIC PLANTS AND ANIMALS WHICH GOT BURIED DEEP INSIDE THE EARLY MILLIONS OF YEARS AGO AND CHANGED INTO FUEL DUE TO EXCESS OF HEAT AND HIGH PRESSURE INSIDE THE EARTH ARE CALLED FOSSIL FUELS .

Fossil fuels -

TYPES OF FOSSIL FUELS1. Liquid Hydrocarbons- Petroleum (oil)2. Coal3. Natural Gas

Coal• Coal exists in many forms therefore a chemical formula cannot be written for it.• Coal is a fossil fuel that is made by

carbonized vegetable material. It is a black-brown sedimentary rock.

•Produces 62% of world’s electricity.•Most abundant fossil fuel and could easily last at least 200 years

Advantages and Disadvantages

Pros• Most abundant fossil fuel• Major U.S. reserves• 300 yrs. at current

consumption rates• High net energy yield

Cons• Dirtiest fuel, highest carbon dioxide• Major environmental degradation• Major threat to health

PETROLEUM

• Petroleum is a fossil fuel and is an oil that is found underground. Sometimes we call it oil. Oil can be as thick and black as tar or as thin as water. Petroleum has a lot of energy. We can turn it into different fuels - like gasoline, kerosene, and heating oil. Most plastics are made from petroleum, too.

• Petroleum is buried underground in tiny pockets in rocks. We drill wells into the rocks to pump out the oil.

NATURAL GAS• Natural gas is a fossil fuel used as a source of

energy for heating, cooking, and electricity generation. It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics.

Natural Gas• Natural gas provides 29% of our

energy and is used to heat about half the homes in the United States.

• It is a raw material in a variety of common products, such as paints, fertilizers, plastics, medicines, and antifreeze.

• Natural gas is also used to generate 33% of our electricity.

FIREWOOD

Fire Wood is a fuel, such as firewood, charcoal, chips, sheets, pellets, and sawdust.

Firewood is wood that has been cut into pieces so that it can be burned on a fire.

firewood used as fuel for a fire.

Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form. Firewood is a renewable resource.

Advantages Wood is a domestic, traditional and renewable resource that is locally available. It CO2-neutral: carbon that is released during burning is part of the natural carbon circulation. The use of wood for energy purposes can have positive effects on forest management. It is usable multiple times because poor quality wood, small wood and scrap wood is primarily used for energy purposes.

EFFECTS OF FOSSIL FUELS• Severe Air Pollution• Greenhouse Effect• Severe damage to

Environment
