A type of coal that contains a lot of moisture and ash and breaks apart easily. Of the four types, lignite has the lowest carbon content and heating value. Lignite is used mainly at electricity-generating plants.

It is the lowest rank of coal, often referred to as brown coal

Electricity tariff for street lighting

A common nuclear reactor cooled and usually moderated by ordinary water

Refers to the density of crude oils and the products refined from them. Heavy crudes are more dense and have higher final boiling points than light crudes which have more asphalt. Products refined from heavy crudes include asphalt, lubricants, waxes, fuel oils. and light fuels (white products). Light crudes yield a higher proportion of light fuels, waxes, lubes, and small amounts of asphalt

Crude oil with a low specific gravity and high API gravity due to the presence of a high proportion of light hydrocarbon fractions

Hydrocarbons with low molecular weight such as methane, ethane, propane and butane

Light fuel oil is a convenient heating fuel used to heat homes and buildings, and a fuel in industry, agriculture and ships. It also makes an ideal reserve and emergency fuel for industrial plants and power stations using other forms of energy

Crude oil with a high API gravity, usually more than 40?
