Direct current (DC) is the unidirectional flow of electric charge.
Alternating current (AC)
In alternating current (AC, also ac), the movement of electric charge periodically reverses direction.
A transformer is a power converter that transfers electrical energy from one circuit to another through inductively coupled conductors
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit
a fuse is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit.
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.
Watt is the unit of electric power. One watt is defined as energy consumption rate of one joule per second.
Kilowatt (symbol: kW) is a unit of electric power. One kilowatt is equal to 1000 watts: 1kW = 1000W.
Electric energy is energy newly derived from electrical potential energy. When loosely used to describe energy absorbed or delivered by an electrical circuit
The kilowatt hour, or kilowatt-hour, (symbol kW·h, kW h or kWh) is a unit of energy equal to 1000 watt hours or 3.6 megajoules.
You can use the EnerGuide label to make informed buying decisions by comparing the energy performance of different products.
A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes.
Time of use pricing
Time-of-Use pricing means that the price you pay for electricity changes depending on the time of day
Refers to the electric power consumed by electronic and electrical appliances while they are switched off
Efficiency in general describes the extent to which time, effort or cost is well used for the intended task or purpose.
The constant or permanent load on a power supply
Hydroelectric power generation
Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water.
The range from base load to a point between base load and peak. This point may be the midpoint, a percent of the peak load, or the load over a specified time period.
The maximum load carried by a device, system, or structure over a designated time period.
Renewable energy source
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, waves and geothermal heat, which are renewable.
Non-renewable energy source
Non-renewable sources of energy can be divided into two types: fossil fuels and nuclear fuel.
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies.
The photovoltaic effect is the creation of voltage or electric current in a material upon exposure to light.
Biomass energy, or bioenergy, is the energy stored in non-fossil organic materials such as wood, straw, vegetable oils and wastes from the forest, agricultural and industrial sectors
