The watt (symbol: W) is a unit of power.In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer.In SI base units, the watt is described as kg⋅m 2 ⋅s −3. The watt is named after James Watt, an 18th-century Scottish inventor.
Electrical energy is energy derived from electric potential energy or kinetic energy.When used loosely, electrical energy refers to energy that has been converted from electric potential energy. This energy is supplied by the combination of electric current and electric potential that is delivered by an electrical circuit (e.g., provided by an electric power utility).

Energy efficiency is playing an increasingly vital role in our lives, for three main reasons: The environment. The more energy we use, the more carbon emissions are pumped into the atmosphere and the more our reserves of natural resources such as oil, coal and gas are depleted.

HERNUBARE energie is energie wat verkry word van bronne wat hulself gedurig hernu of vir alle praktiese doeleindes nie uitgeput kan word nie. Hernubare energiebronne verskil dus grootliks van fossielbrandstowwe (aardgas, olie en steenkool) en produseer nie soveel kweekhuisgasse en besoedelende stowwe as eersgenoemde nie.

Energie, algemeen en kwalitatief gesproke, is die eienskap waardeur die doen van dinge of die verskaffing van krag moontlik gemaak word. Die uitdrukkings "energie" en "krag" word soms foutiewelik uiteenlopend gebruik, maar dit het verskillende betekenisse op beide die wetenskaplike en nie-wetenskaplike gebiede. Fisika poog om die eienskap kwantitatief te beskryf en gee daaraan n …
