Our consumption of electricity has a...
major effect on our environment. Most electricity is produced by burning coal - a LOT of coal. Burning of coal is highly polluting and release CO2 into the atmosphere.

Top 6 facts about consumption of electricity

1

Electricity use is in rapid growth

The world's demand for electricity will grow by 85 percent between 2010 and 2040 - this increase is more than today's total use of electricity in the USA, the European Union, China, Russia, Japan, Australia and India.


2

It does not come from windmills

The burning of coal is the worlds largest source of electricity. If nothing changes most of the increased production of electricity will come from burning more coal. A LOT more!


3

Do you put your stereo on standby?

Here is something that might surprise you: over the next 10 years, the power used by products in “standby” could be as high as 10 percent of total electricity use. Powering these will require 400 medium-sized power plants. It's a good thing that we have a lot of coal to burn…


4

Coal plants are ineffective

Only 35 percent of coal's energy (and some say at the most) is made into electricity in coal-fired power plants. The rest is lost as waste heat.


5

Coal burning uses up water too...

A typical coal-fired power plant uses massive amounts of water to create steam for turning its turbines. Enough water to support a city of approximately 250,000 people.


6

...and pollutes the air

Burning coal is a leading cause of smog, acid rain, global warming, and air toxics.



Consumption of electricity

The world consumes 21,325,115 GWh of electricity a year equivalent to 76,770,414 terajoules. Electricity is a carrier of energy. It is the flow of electrical power or charge, made by converting “primary” sources of energy such as coal, oil, gas, wind, and solar 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 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.
