| We now use over 100 times more energy today than we did 200 years ago. Energy resources available to us include coal, oil, natural gas, nuclear power, geothermal power, hydroelectric power, wood and windpower. |
Oil is the core energy resource of the modern world and provides us with nearly 40% of the total world's energy. We can find the largest reserves of this energy source in the Middle East. It is there that it is refined in great quantities and shipped elsewhere in the world. Oil is commonly referred to as 'black gold' as it is an extremely valuable commodity.
Natural gas is another big energy resource and provides the world with 20% of its energy. Coal accounts for 30% and two thirds of this energy resource are held by China, USA, Canada and Russia. France, USA and Russia are the world's biggest nuclear power providers. As far as total energy consumption goes, Europe, North America and Japan use a total of 70%, although they have only a quarter of the total population.
Fossil fuels are fuels such as coal, natural gas and oil. These are created from organic minerals that have been fossilized over millions of years. They provide us with over 90% of our world's total energy source although they pollute the earths atmosphere and cause effects like acid rain and global warming. Constant energy sources are referred to as renewable resources as they will never be exhausted by human consumption. Renewable energy resources include windpower, water-generated energy using running water and waves, wind and sunlight. Solar power is an energy resource that uses the sun's energy to generate our own.
