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.

Solar panels, usually roof-mounted, use the energy of the sun to generate electricity for home use, with the potential to sell surplus back to the grid. Light shining on a panel of photovoltaic cells creates an electric field across layers of semiconductive material, causing electricity to flow.

Carbon is the fourth most common chemical element in the universe, and carbon compounds - in other words, carbon chemically combined with other elements - are the basis of all known life forms on earth. Pure carbon appears in many apparently diverse forms, from diamond to graphite to charcoal, but it is much more commonly found in substances such as coal, oil, natural gas, wood and peat that we use for fuel. When we burn these substances to provide energy - either directly in our homes as heat, or in power stations to produce electricity - the combustion process produces 'oxides' of carbon, including the gas CO2.

The second lowest level of the atmosphere, extending from about 10km to about 50km altitude. The ozone layer, the part of the earth's atmosphere with the greatest concentration of ozone, forms part of the stratosphere. Because it sits above the troposphere, where most air turbulence occurs, the lower stratosphere is where most commercial airlines set their cruising altitude.

The process whereby technological advances are shared between different countries. Developed countries could, for example, share up-to-date renewable energy technologies with developing countries, in an effort to lower global greenhouse gas emissions.

A thermostat maintains the temperature of a system at or near a stipulated level using sensors that tell it when to turn off heating devices. In most household central heating systems, a wall-mounted thermostat is used to set a maximum temperature for the house, while thermostatic radiator valves can be used to set a desired level for individual radiators.
