light petroleum products
include liquefied petroleum gas (LPG), naphtha and gasoline.
liquefied natural gas (LNG)
natural gas that has been liquefied by reducing its temperature to -162°C at atmospheric pressure. In this way, the space requirements for storage and transport are reduced by a factor of over 600.
liquidity
the ability to sell assets without significant movement in the price and with minimum loss of value.
low-carbon technologies
technologies that produce low – or zero – greenhouse-gas emissions while operating. In the power sector this includes fossil-fuel plants fitted with carbon capture and storage, nuclear plants and renewable-based generation technologies.
lower heating value
the heat liberated by the complete combustion of a unit of fuel when the water produced is assumed to remain as a vapour and the heat is not recovered.

lb
pound
lt
