A fluorescent bulb or tube uses the flow of electricity to excite mercury vapour in an inert gas (argon or neon), which creates invisible ultraviolet light. A coating of phosphor on the inside of the glass then converts this into visible light - a process known as fluorescence. They have higher energy efficiency and longer life than traditional incandescent bulbs. See also CFLs/low-energy lightbulbs.

A product's 'food miles' indicate how far it has travelled to get from where it (or its ingredients) were grown to where you eat them. Food freight - especially by air and road - is very carbon intensive.

Fossil fuels are the deposits of crude oil, natural gas and coal formed by the decay, over millions of years, of organic material (plants, trees animals and bacteria). Because the combustion of fossil fuels releases carbon that has been out of the natural carbon cycle for so long (unlike with living or more recently dead organic matter, known as biomass) it affects the balance between stored carbon and carbon present in the atmosphere as CO2, a greenhouse gas.

Fuel duty is the tax the government levies on fuel used for transportation, imposed at the point of sale.

How many miles a vehicle will travel for each litre of fuel used
Industry:Natural environment
The injection of carbon dioxide into underground geological formations. When CO2 is injected into declining oil fields it can help to recover more of the oil.

Geothermal energy is energy from the inner core of the earth where molten rock heats the water just below the surface of the earth, or from the sun's energy trapped just below the earth's surface. This energy, hot water or steam can then be distributed to heat buildings. It is the reason we have natural spas. This natural heat has been used to heat buildings and water supplies since Roman times. See also ground source heat pump.
Industry:Natural environment
The mean surface temperature of the Earth measured from three main sources: satellites, monthly readings from a network of over 3,000 surface temperature observation stations and sea surface temperature measurements taken mainly from the fleet of merchant ships, naval ships and data buoys.
Industry:Natural environment
An observed widespread reduction in sunlight at the surface of the Earth, which varies significantly between regions. The most likely cause of global dimming is an interaction between sunlight and microscopic aerosol particles from human activities. In some regions, such as Europe, global dimming no longer occurs, thanks to clean air regulations.
