Sonnenkollektoren, in der Regel Dach montierte, nutzen die Energie der Sonne zur Stromerzeugung für den Heimgebrauch, mit dem Potential, überschüssige zurück an das Netz zu verkaufen. Licht auf einem Panel von Solarzellen erzeugt ein elektrisches Feld über mehrere Ebenen, die halbleitende Materialien, wodurch Strom fließen.

Ein solar-Warmwasserspeicher nutzt die Energie der Sonne direkt um eine Flüssigkeit erhitzt, die in Ihren Warmwasserspeicher eingespeist wird, d. h. Ihr Kessel weniger Arbeit hat zu tun (und weniger Energie erfordert) um Ihr heißes Wasser auf die erforderliche Temperatur bekommen.

Dioxine sind Chlor-haltige chemische Verbindungen gebildet und Ableitungen in die Atmosphäre in der Regel als Nebenprodukte der menschlichen Tätigkeit - Abfall Verbrennung und Brennstoffe werden gängige Beispiele. Sie werden auch durch natürliche Prozesse wie Waldbrände und Vulkane gebildet. Einige Dioxineund haben schädliche Eigenschaften, in hinreichender Konzentration schädlich sein könnte für die Umwelt und die menschliche Gesundheit.

Global warming refers to the increase in the earth's surface (or near-surface) temperature in recent decades due to higher levels of greenhouse gases, and the projected worsening of this effect over time.

A hybrid car is one that has both a petrol engine and an electric motor and switches between them according to the driving conditions. It is different from a dual-fuel vehicle, which uses two types of liquid fuel.

Hydrocarbons are compounds made up of hydrogen and carbon only. All fossil fuels - such as coal, oil and gas - are hydrocarbons, until they are burnt when they mix with oxygen, creating (amongst other gases) CO2.

Inert gases are those, including helium and neon, that are not normally chemically reactive. The inert gases argon and krypton are often used in sealed double glazing units because they don't conduct heat as well as air, so they provide better insulation.

Mercury (chemical symbol Hg) is a metal that is liquid at standard temperature and pressure. It is used in the manufacture of low-energy lightbulbs (CFLs and other fluorescent lights), and extra care must be taken in their disposal, especially when they are broken, because of mercury's toxicity.

Methane is a hydrocarbon, the main component of natural gas and among the six greenhouse gases to be curbed under the Kyoto protocol. As a greenhouse gas it is estimated to have a warming effect about 25 times as great as CO2. (Compared to CO2 its effects are greater but last for a shorter period). As a fuel, it is used in electricity generation and in the form of compressed natural gas it can be used as vehicle fuel. Methane is produced during the decomposition of many materials in landfill, while about 16% of methane emissions are caused by livestock's digestive processes.
