in the world? Briefly, a lot! And it will continue to grow in the foreseeable future making green energy innovation absolutely essential. As it is now, most energy comes from burning coal...

Top 5 facts about use of energy

1

We use a lot of energy

The world uses over 500 million terajoules of energy in one year. This corresponds to the energy released from the Hiroshima nuclear bomb every four seconds. A Boeing 737 can cross the Atlantic Ocean on one terajoule.


2

Most energy comes from fossil fuels

81 percent of the energy we use comes from burning oil, coal, and gas - also known as fossil fuels.


3

Our energy consumption is increasing

Our use of energy will grow by about 35 percent between 2011 and 2035. If nothing changes, most of this increase will be covered by burning more coal.


4

Renewable energy is rising

Between 2011 and 2030 renewable energy is expected to grow from 2 to 6 percent of global primary energy use.


5

What is renewable energy?

Main renewable energy sources include hydropower, bio-mass heating, solar power, and geothermal heating.



Use of energy

A terajoule is a measure of energy. One terajoule equals 1 billion joules - a unit of energy named after English physicist James Prescott Joule, who developed the theory of conservation of energy and the first law of thermodynamics in the 19th century. In everyday terms, a joule is the amount of energy needed to lift an apple about one meter against the Earth's gravity. World energy use is 143.851 petawatt hours a year equivalent to. 517,863,600 terajoules (1 petawatt hour = 3 600 000 terajoules).
