Natural gas

600 million years old

What is natural gas?

Natural gas is the most environmentally sound of all fossil fuels. In Belgium, it accounts for almost 25% of primary energy consumption.

 

Fossil fuel

Natural gas is produced through the decomposition of organic animal and vegetable matter. That is why it is called a fossil fuel. It is non-toxic and consists primarily (90%) of methane (CH4) and other hydrocarbons, such as butane and propane. The natural gas we use today is approximately 600 million years old.

Tips for using search operators

Use "quotation marks" to search for a series of words or a phrase in a specific order.

Boolean operators

You can find a group of words or a phrase by using the link words AND, OR and NOT:
known as Boolean operators, these words are used to combine terms in the search field.

  • AND: All the search terms must be included in the publication. Typing in Apple AND Pear will return publications containing both the word Apple and the word Pear.

     

  • OR :  At least one of the search terms must be included in the publication. Typing in Apple OR Pear will return publications containing either the word Apple or the word Pear or both.

     

  • NOT: The term preceded by NOT must not be included in the publication. Typing in Apple NOT Pear will return publications containing the word Apple but not the word Pear.
