World_Energy_consumption.png
From the diagram above we can see that the world's energy consumption is heavily depended upon oil, coal and gas. These are all fossil fuels. Over the last 40 years the consumption of fossil fuels has been continuously increasing. Between 1980 and 2004, the worldwide annual growth rate was 2%.


Fossil-fuel Power Plant

A fossil-fuel power plant is a power plant that burns fossil fuels such as coal, natural gas or petroleum (oil) to produce electricity.The main systems are the steam cycle and the gas turbine cycle.

These are the basic steps power stations used to generate electrical power from fossil fuel:

These Youtube Video and animation explain how do the power stations work:

The world has more than 2000 fossil fuel power plants. Annually, the world consumes more than 4,500,000,000 ton of coal and 85,000,000 barrels of oil per day.


Coal-fired Power Plant

A typical (500 megawatt) coal plant burns 1.4 million tons of coal each year. There are about 600 U.S. coal plants. Coal supplies about 28% of our electricity.

Oil-fired Power Plant

Each year, 120,000 tons of crude oil are burned by a oil plant to generate 100MW of electricity.
