Electricity consumption in the production of aluminium

Using the figures above this means that 621 billion kilowatt hours of electrical energy were used in the production of aluminium. To put that in perspective, the total world production of electrical energy was 20261 billion kilowatt hours, meaning that more than 3% of the world's entire electrical supply went to extraction of aluminium.

Energy Definition and Examples

According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form. Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat at the point of collision.

How does recycling save energy?

Extracting and processing raw resources (wood, oil, ore) to make usable materials (paper, plastic, metal) requires a lot of energy. Recycling often saves energy because the products being recycled usually require much less processing to turn them into usable materials. Exactly how much energy is saved depends on the material in question. Let

Nuclear Power Education

Nuclear Power is produced when a nucleus absorbs a neutron and splits into two lighter nuclei. This releases enormous amounts of energy which in turn produces heat. In fact the Uranium, which is the most common element used to produce nuclear power today, has an energy content about 3 million times greater than that of fossil fuel.

Gold: History of Use, Mining, Prospecting, Assay

Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.

Silver

The Romans used silver in this way as early as 269 BC (more than 2000 years ago). Because silver is such a good conductor of electricity, it is used in many electrical applications, including switches, contacts and fuses. Silver is used in switch contacts because it does not corrode - corrosion can cause overheating, leading to fire.
