In Canada, the term hydro is often used to refer to electricity. This is because a large proportion of Canada's electricity is generated using hydropower, or hydroelectric power, which uses the natural flow of moving water to generate electricity. Hydropower is one of the largest sources of renewable energy and is used in all but two US states. In Canada, hydropower provides 60% of the country's electricity generation. The term hydro is also used in the names of electrical utility companies in certain Canadian provinces, such as Ontario and British Columbia, which may have contributed to the use of the term to refer to electricity more generally.

Hydro is a short form for hydroelectricity
In Canada, electricity is often called "Hydro" by Canadians, as most of the electricity generated is from hydropower. The use of the term "hydro" in Canada can be traced back to the founding of the Hydro-Electric Power Commission of Ontario in 1906, which was created to build transmission lines to power municipalities using power generated by private companies at Niagara Falls. While the term "hydro" is used across Canada, it is more common in some provinces than others. For example, in Ontario, the term "hydro bill" is used to refer to the electric bill, and Ontario Hydro is a shortcut for Ontario Hydro-electric power. In British Columbia (BC), the term "hydro" is used to refer to the power company, BC Hydro, and not the electricity itself. In Saskatchewan, the term "hydro" is understood but not commonly used, and in New Brunswick (NB), the term "power" is more commonly used, although hydro is also used.
In the United States, hydropower is also a significant source of electricity, accounting for 27% of total U.S. utility-scale renewable electricity generation and 5.86% of total U.S. utility-scale electricity generation. All but two states, Delaware and Mississippi, use hydropower for electricity, and in 2023, about 60% of Washington state's electricity came from hydropower. However, it is unclear if the term "hydro" is commonly used to refer to electricity in the United States, as it is in some parts of Canada.

Hydro is used to refer to electricity in Canada
In Canada, the term "hydro" is commonly used to refer to electricity, specifically hydroelectricity. This usage is particularly prevalent in certain provinces such as Ontario, Quebec, British Columbia (BC), and the Maritimes. The association between "hydro" and electricity in Canada can be traced back to the early 20th century when hydroelectric power was the primary source of electricity in the country.
The term "hydro" in this context is derived from the word "hydroelectricity," which refers to electricity generated from hydropower or water power. Hydropower uses the natural flow of moving water, often in conjunction with dams, to generate electricity. It is one of the oldest and largest sources of renewable energy, offering a clean and flexible form of electricity generation. In Canada, moving water or hydropower accounts for a significant portion of the country's electricity generation, estimated at 60% in 2020.
The usage of "hydro" to refer to electricity is deeply ingrained in the Canadian provinces that rely heavily on hydroelectric power. For example, in Ontario, the term “hydro bill” is commonly used to refer to the electric bill, and the company Ontario Hydro was historically associated with providing hydroelectric power to the province. Similarly, in Quebec, the term "hydro" is commonly used in the parlance of the province's electrical utility company, Hydro-Quebec.
However, it is important to note that the usage of "hydro" to refer to electricity is not universally consistent across Canada. In provinces like Saskatchewan, the term “power” is predominantly used instead of "hydro." Additionally, some individuals from other provinces, such as British Columbia, clarify that they call the company "Hydro" but not the electricity itself. The usage of "hydro" as a shorthand for electricity appears to be influenced by the names of the regional power companies, as well as the historical reliance on hydroelectric power in certain regions.
Furthermore, it is worth mentioning that the term "hydro" can sometimes lead to confusion, especially for newcomers or individuals from other regions. This is because "hydro" technically means water, and using it to refer to electricity can be odd and nonsensical to those unfamiliar with the Canadian context. Nevertheless, the usage of "hydro" to refer to electricity in Canada is a well-established shorthand that reflects the country's historical and ongoing reliance on hydroelectric power as a significant source of energy.

Hydropower is a renewable source of energy
Hydropower, or hydroelectric power, is a renewable source of energy. It uses the natural flow of water to generate electricity. This technology has been in use for thousands of years, with the Greeks using water wheels to grind wheat into flour over 2,000 years ago. The modern hydropower turbine was developed in the mid-1700s by French engineer Bernard Forest de Bélidor, and the field has seen many advancements since.
Hydropower is one of the largest sources of renewable energy, currently accounting for 27% of renewable electricity generation in the US and over 50% worldwide. It is also one of the most affordable sources of electricity, with relatively low costs over the full project lifecycle in terms of maintenance, operations, and fuel. Hydropower facilities can vary in size, from large dams to small irrigation ditches, and can even be "damless".
Despite its benefits, hydropower is not considered a renewable energy source in most US states and by the federal government. This is partly due to the impact of counting hydropower in renewable energy standards, which could discourage the development of new renewable sources and lead to unrealistically high targets. Additionally, some states have specific criteria for including hydropower in their renewable energy counts, such as limiting it to small hydropower projects or requiring it to be non-harmful to wildlife.
However, hydropower is a key component in achieving global net-zero targets and provides essential power, storage, flexibility, and climate mitigation services. It is also one of the cleanest sources of electricity, with low greenhouse gas emissions per unit of energy generated. According to the IEA, doubling the existing capacity of hydropower will be necessary to achieve a cost-effective global net-zero energy system by 2050.

Hydropower, or hydroelectric power, is a renewable energy source that uses the natural flow of water to generate electricity. It is one of the oldest and largest sources of renewable energy, with a long history of human use. The Greeks, for instance, used water wheels for grinding wheat into flour over two thousand years ago.
Hydropower is a significant component of renewable electricity production globally, accounting for more than 50% of such production. In 2022, hydropower contributed to about 15% of total electricity generation from all sources. The largest hydropower-producing countries by installed capacity include China, Brazil, the USA, Canada, and India.
Hydropower is a clean energy source with near-zero emissions, fuelled by water, which is constantly replenished through the water cycle. It is also cost-effective, with relatively low costs over the full project lifetime due to its longer lifespan, reduced maintenance, and extended equipment operation. Hydropower facilities come in all sizes and can be dammed or damless.
Hydropower has several advantages, including its reliability as a consistent and predictable source of energy, unlike weather-dependent solar and wind power. This makes it a valuable source of baseload power, providing a stabilizing effect on the power grid. Additionally, hydropower plants can provide immediate backup power during major electricity outages, as well as benefits like flood control, irrigation support, and water supply.
However, there are also potential drawbacks to hydropower technologies. Large-scale projects can have significant environmental impacts, including community displacement and disruption of natural river ecosystems. Other challenges include ensuring sustainability, adapting to modern power system requirements, and addressing outdated market structures.

Hydropower is used in most US states
Hydropower is a renewable source of energy that is used to generate electricity for human use. It is considered to have several advantages over other sources, including minimal pollution since no fuel is burned, low maintenance costs, and reliable technology. In the United States, hydropower is used in most states, with nearly all states having conventional hydroelectric facilities.
The United States is a leading producer of hydroelectric power globally, ranking third or fourth, depending on the source. In 2021, the total installed capacity for hydroelectric power in the US was 102.8 GW, with a generation capacity of about 80 million kilowatts in 2018 and 2023. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which was the source of 44% of the nation's hydroelectricity in 2012.
Hydropower has a long history in the United States, with the first DC powerhouse established in Grand Rapids, Michigan, in 1880. By 1886, there were between 40 and 50 hydroelectric stations operating in the country, and by 1888, about 200 electric companies relied on hydropower for at least part of their generation. The development of long-distance power transmission systems further encouraged the use of hydropower, with electricity transmission from Niagara Falls to Buffalo, New York, beginning in 1896.
Today, the leading states in hydropower production include Washington, California, Oregon, New York, and Alabama. Washington state, home to the Grand Coulee Dam, contributes 37% of the country's total hydropower production. California has 270 hydroelectric facilities, while Oregon has 88, with hydropower accounting for 11% of the United States' total hydropower capacity. New York, the leading producer east of the Mississippi River, has more than 300 hydroelectric generating stations, with the largest being the Robert Moses Niagara Power Plant.
