The lowest level of the atmosphere, from the surface to about 10km. It is the level at which clouds form and where our weather phenomena occur.

A business or a process is described as carbon neutral if it doesn't add to the net amount of CO2 in the atmosphere. This can be achieved either by emitting no CO2 to begin with - by using only renewable energy, say - or by 'offsetting' emissions (a controversial issue) which means compensating for emissions by another action which might reduce atmospheric CO2, such as planting trees. In practice, it is impossible for a person to live in an entirely carbon neutral way because even if you cut out energy consumption derived from fossil fuels, most products and services people rely on will have embodied emissions.

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.
Industry:Natural environment
A device used to measure the volume of water used by a household or business. Billing people for the water they actually use, rather than a fixed annual charge, is increasingly common in the UK, and is regarded as an incentive to users to avoid wasting water.
Industry:Natural environment
A way of compensating for emissions of CO2 by participating in, or funding, efforts to take CO2 out of the atmosphere. Offsetting often involves paying another party, somewhere else, to save emissions equivalent to those produced by your activity.

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.
Industry:Natural environment
The process of storing carbon dioxide. This can happen naturally, as growing trees and plants turn CO2 into biomass (wood, leaves, and so on). It can also refer to the capture and storage of CO2 produced by industry. See Carbon capture and storage.

A watt is a unit of power. Power is the rate at which energy is used, and a watt is equal to a rate of one joule of energy per second. Watts are commonly used when referring to the energy consumption of relatively small things like lightbulbs, while kilowatts (a thousand watts) are used for larger machines. Megawatts (a million watts) are used to measure the electricity generation of power stations. See also kilowatt-hours.
Industry:Natural environment
Any process, activity or mechanism that removes carbon from the atmosphere. The biggest carbon sinks are the world's oceans and forests, which absorb large amounts of carbon dioxide from the Earth's atmosphere.
Industry:Natural environment
The state of the atmosphere with regard to temperature, cloudiness, rainfall, wind and other meteorological conditions. It is not the same as climate which is the average weather over a much longer period.
