In the SI, the same is used as for any other kind of energy: the Joule.
A solar calculator typically uses photovoltaic cells to convert sunlight into electrical energy. This type of energy is clean and renewable, making solar calculators an environmentally friendly choice. It allows the calculator to function as long as there is enough light available.

A concave mirror is used in a solar cooker to focus sunlight at a single point, increasing the intensity of the heat produced. This concentrated heat is then used for cooking food or heating water efficiently. The shape of the concave mirror allows for better collection and concentration of sunlight compared to a flat mirror.

Mostly coal-fired power plants, black coal outside Victoria, where dirty brown coal (lignite) is used. There a considerable level of hydroelectric energy utilisation mainly in Tasmania, which has only one coal-fired power station. There are no nuclear power plants. Wind energy is becoming more important with small-scale solar plants coming onstream as well, although "alternative" sources of enegy amount to only a small proportion of Australian enegy needs.
