Electricity Power Explained

Electricity Power

The make up of the electricity power sector has been in transition over recent history. In most provinces, there has been a transition from traditional electric utilities (which are mostly provincially-owned crown corporations) to private generation, transmission and distribution assets.

In 2014, Canadian eutilities and industrials generators produced more than 639 terawatt hours of electricity. When it comes to hydroelectric power, Canada is the world's second largest producer. Hydroelectricity accounts for 59.3 per cent of Canada’s supply. Other energy sources that contribute to the transfer of energy include: coal, uranium, natural gas, petroleum and non-hydro renewable energy sources. About 67 per cent of Canada’s energy comes from renewable sources like wind, solar and hydroelectric power stations and 82% from non-greenhouse gas emitting sources.

In 2014, almost 59 terawatt hours of electricity exported to the USA, while about 13 terawatt hours was imported from the United States.

Canada's industrial sector is responsible for the largest share of electricity demand because there are a number of energy-intensive industrial activities like mining, oil and gas production, pulp and paper production, and other primary industry uses. Residential and commercial sectors consume much smaller quantities of electricity for lighting (light bulb), heating, and communications.

R&D programs aimed at maintaining the operating capability of the nation’s existing nuclear power plants and developing the next generation of nuclear technologies. Nuclear energy is the world’s largest source of emission-free electricity power. The Nuclear Energy program is working to develop cost-efficient technologies that further enhance nuclear safety, minimize the generation of nuclear waste, and further reduce the risk of proliferation.

To meet the rising demand of the 21st century, significant improvements in America’s electric system are necessary. Blackouts serve as a powerful reminder of the critical role electricity plays in the everyday lives of people.

 

Voltages, currents, power energy

When it comes to electric current, electrical voltage, electric circuit dynamics and energy powers, all rely on the flow of the electron. What this means is that power voltage feeds loads, solid state power load devices, and other loads that need electric power. Electric power is the rate at which that power is measured in watts or voltage in volts. There are various forms of energy measured in si unit: apparent power, reactive power, ac power, real power in watts, etc.

Electrical Engineers and Scientists alike seek common views in order to develop new technologies for the storage of energy and the transmission of electric potential through power circuits that will contribute to energy efficiency of the electric industry. For instance, the copper wires used in typical transmission lines lose a percentage of the electricity passing through them because of resistance over long distances, which causes the wires to heat up. But "superconducting" materials have no resistance, and if they are used to transmit electricity in the future, very little of the electricity will be lost.
