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.

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.

Диоксините са хлор съдържащи химични съединения образуват и отделяни в атмосферата обикновено като странични продукти на човешката дейност - отпадъците изгаряне и изгарянето на горива, са честите примери. Те също така са формирани от естествени процеси, като горски пожари и вулкани. Някои диоксините са вредни свойства и могат в концентрация, достатъчна, да навредят на околната среда и човешкото здраве.

Climate change is the variation in the average global or regional climate as measured by yardsticks such as average temperature and rainfall. This variation is caused by both natural processes and human activity. Weather is what happens over days or even hours, whereas climate is the average weather measured over a longer period. Increasingly when people refer to climate change, however, they specifically mean the phenomenon of global warming.

Organic matter that can break down or decompose rapidly under natural conditions and processes is referred to as biodegradable. Garden and food waste, animal waste, and most paper products, as well as plastics derived from vegetable content, will biodegrade, but not plastic carrier bags and polystyrene cups, for example.

The soot that results from the incomplete combustion of fossil fuels, biofuels, and biomass (wood, animal dung, etc.). It is the most potent climate-warming aerosol. Unlike greenhouse gases, which trap infrared radiation that is already in the Earth's atmosphere, these particles absorb all wavelengths of sunlight and then re-emit this energy as infrared radiation.

Turbulence describes irregular eddies of air within the general air current. It can be caused when wind flows over obstacles such as trees or buildings and gets 'churned up', so it no longer has a smooth flow. Wind turbines do not handle turbulence well and power production can be dramatically decreased.

Water pressure is the force that pushes water through pipes and determines the rate of flow from your taps. Water companies are required to provide water at a pressure that will reach the upper floors of houses, but where this is a problem, pressure can be improved using pumps. However, devices such as power showers, which use a pump to boost flow for a more powerful shower spray, also greatly increase the volume of water used and the energy required to heat it.

An agreement between two parties whereby one party struggling to meet its emission reductions under the Kyoto Protocol earns emission reduction units from another party's emission removal project. The JI is a flexible and cost-efficient way of fulfilling Kyoto agreements while also encouraging foreign investment and technology transfer.
