The electricity sector in Canada has played a significant role in the economic and political life of the country since the late 19th century. The sector is organized along provincial and territorial lines. In a majority of provinces, large government-owned integrated public utilities play a leading role in the generation, transmission, and distribution of electricity. Ontario and Alberta have created electricity markets in the last decade to increase investment and competition in this sector of the economy.

Canada has access to all main sources of energy including oil and gas, coal, hydropower, biomass, solar, geothermal, wind, marine and nuclear. It is the world's second largest producer of uranium, third largest producer of hydro-electricity, fourth largest natural gas producer, and the fifth largest producer of crude oil. In 2006, only Russia, the People's Republic of China, the United States and Saudi Arabia produce more total energy than Canada.
Wind power in Texas, a portion of total energy in Texas, consists of over 150 wind farms, which together have a total nameplate capacity of over 30,000 MW. If Texas were a country, it would rank fifth in the world: The installed wind capacity in Texas exceeds installed wind capacity in all countries but China, the United States, Germany and India. Texas produces the most wind power of any U.S. state. According to the Electric Reliability Council of Texas (ERCOT), wind power accounted for at least 15.7% of the electricity generated in Texas during 2017, as wind was 17.4% of electricity generated in ERCOT, which manages 90% of Texas's power. ERCOT set a new wind output record of nearly 19.7 GW at 7:19 pm Central Standard Time on Monday, January 21, 2019.
The electricity policy of Alberta, enacted through several agencies, is to create an electricity sector with a competitive market that attracts investors, while providing consumers with reliable and affordable electricity, as well as reducing harmful pollution to protect the environment and the health of Albertans, according to their 2022 website.
China is the world's largest electricity producer, having overtaken the United States in 2011 after rapid growth since the early 1990s. In 2021, China produced 8.5 petawatt-hour (PWh) of electricity, approximately 30% of the world's electricity production.
The electricity sectors of the Republic of Ireland and Northern Ireland are integrated and supply 2.5 million customers from a combination of coal, peat, natural gas, wind and hydropower. In 2022, 34 TWh were generated. In 2018 natural gas produced 51.8%, while wind turbines generated 28.1%, coal 7%, and peat 6.8% of Ireland's average electricity demand. In 2020 wind turbines generated 36.3% of Ireland's electrical demand, one of the highest wind power proportions in the world. While the United Kingdom was one of the first countries in the world to deploy commercial nuclear power plants, the island of Ireland has never had a nuclear power plant built on either side of the Irish border. Nuclear power in Ireland was discussed in the 1960s and 1970s but ultimately never phased in, with legislation now in place explicitly forbidding its introduction.
Capital Power is a North American independent power generation company based in Edmonton, Alberta, Canada. It develops, acquires, owns and operates power generation facilities using a variety of energy sources.
The United States has the second largest electricity sector in the world, with 4,178 Terawatt-hours of generation in 2023. In 2023 the industry earned $491b in revenue at an average price of $0.127/kWh.
Different methods of electricity generation can incur a variety of different costs, which can be divided into three general categories: 1) wholesale costs, or all costs paid by utilities associated with acquiring and distributing electricity to consumers, 2) retail costs paid by consumers, and 3) external costs, or externalities, imposed on society.
AltaLink, L.P. is one of Canada's largest electricity transmission companies. Based in Alberta, AltaLink is responsible for the maintenance and operation of approximately 12,000 kilometres of transmission lines and 280 substations in Alberta. AltaLink is owned by Berkshire Hathaway Energy.
The National Grid covers most of mainland Great Britain and several of the surrounding islands, and there are interconnectors to Northern Ireland and to other European countries. Power is supplied to consumers at 230 volts AC with a frequency of 50 Hz. In 2023 about a third of electricity used in Britain was generated from fossil gas and two-thirds was low-carbon power. Wind generates the most low-carbon power, followed by nuclear some of which is imported from France. The government is aiming for greenhouse gas emissions from electricity in Britain to be net zero by 2035.
Energy is a major area of the economy of California. California is the state with the largest population and the largest economy in the United States. It is second in energy consumption after Texas. As of 2018, per capita consumption was the fourth-lowest in the United States partially because of the mild climate and energy efficiency programs.
Electricity sector in Hong Kong ranges from generation, transmission, distribution and sales of electricity covering Hong Kong. The combustion of coal, natural gas and oil are the main sources of electricity in Hong Kong. The electricity sector contributes 60.4% of Hong Kong's total greenhouse gas emissions.
The electricity sector in the Philippines provides electricity through power generation, transmission, and distribution to many parts of the country. The Philippines is divided into three electrical grids, one each for Luzon, the Visayas and Mindanao. As of June 2016, the total installed capacity in the Philippines was 20,055 megawatts (MW), of which 14,348 MW was on the Luzon grid. As of June, 2016, the all-time peak demand on Luzon was 9,726 MW at 2:00 P.M. on May 2, 2016; on Visayas was 1,878 MW at 2:00 P.M. on May 11, 2016; and on Mindanao was 1,593 MW at 1:35 P.M. on June 8, 2016. However, about 12% of Filipinos have no access to electricity. The Philippines is also one of the countries in the world that has a fully functioning electricity market since 2006 called the Philippine Wholesale Electricity Spot Market(WESM) and is operated by an independent market operator.
