Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.

Sihwa Lake Tidal Power Station is the world's largest tidal power installation, with a total power output capacity of 254 MW. When completed in 2011, it surpassed the 240 MW Rance Tidal Power Station which was the world's largest for 45 years. It is operated by the Korea Water Resources Corporation.
The Kapichira Power Station is a hydroelectric power plant at the Kapachira Falls on the Shire River in Malawi. It has an installed capacity of 128 megawatts (172,000 hp), enough to power over 86,000 homes, with four 32 megawatts (43,000 hp) generating sets. The power station was developed in stages, with the first phase involving the installation of the first two 32 megawatts-generating turbines. Phase I of the power station was officially opened in September 2000.
The Incheon Tidal Power Station is a large tidal power station proposed for Incheon Bay, South Korea. The facility is designed to top 1,320 megawatts (1,770,000 hp) in generating capacity with the help of 44 water turbines rated at 30 megawatts (40,000 hp) each, which would make this facility the largest of its kind in the world. The construction and developments costs are expected to reach ₩3.9 trillion, of which would be entirely covered by private funding. The station is expected to generate up to 2.41 TWh of energy annually.
Uldolmok Tidal Power Station is a tidal power station in Uldolmok, Jindo County, South Korea. The plant was commissioned in May 14, 2009 by the South Korean government. The plant cost US$10 million and has an installed capacity of 1,000 KW, generating 2.4 GWh annually, sufficient to meet the demand of 430 households. Additional 500 kW was commissioned in June 2011.
A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces.
Renewable energy in Russia mainly consists of hydroelectric energy. In 2010, the country was the sixth largest producer of renewable energy in the world, although it was 56th when hydroelectric energy was not taken into account. Some 179 TWh of Russia's energy production came from renewable energy sources, out of a total economically feasible potential of 1823 TWh. 16% of Russia's electricity was generated from hydropower, and less than 1% was generated from all other renewable energy sources combined. Roughly 68% of Russia's electricity was generated from thermal power and 16% from nuclear power.
Rwimi Hydroelectric Power Station, also Rwimi Power Station, is an operational 5.54 megawatts (7,430 hp) hydroelectric power station in the Western Region of Uganda.
Siti I Hydroelectric Power Station, commonly referred to as Siti Power Station, is a 5.0 megawatts (6,700 hp) mini hydropower station in Uganda.
Chichonki Malian Hydropower Plant (CMHPP) is a small, low-head, run-of-the-river hydroelectric generation station of 13.2 megawatts (17,700 hp) generation capacity (three units of 4.4 megawatts (5,900 hp)each), located at Sheikhupura, about 35 kilometres (22 mi) north-west of Lahore, Punjab province of Pakistan, on the flows of Upper Chenab Canal. It is a small hydro power generating plant constructed and put in commercial operation in May 1959 with the average annual generating capacity of 22.88 million GWh of inexpensive electricity.
The Aluto–Langano Geothermal Power Station, also known as Aluto Langano Geothermal Power Station, is the only geothermal power station in Ethiopia.
The Tedzani Hydroelectric Power Station, also Tedzani Hydroelectric Power Complex, is a complex of integrated hydroelectric power plants across the Shire River in Malawi. It has installed capacity of 111.7 megawatts (149,800 hp), with four power stations adjacent to each other, sharing some of the physical infrastructure and electro-mechanical connections.
Zambia is potentially self-sufficient in sources of electricity, coal, biomass and renewable energy. The only energy source where the country is not self-sufficient is petroleum energy. Many of the sources of energy where the country is self-sufficient are largely unexploited. As of 2017, the country's electricity generating capacity stood at 1,901 megawatts.
In 2019, Wales generated 27% of its electricity consumption as renewable electricity, an increase from 19% in 2014. The Welsh Government set a target of 70% by 2030. In 2019, Wales was a net exporter of electricity. It produced 27.9 TWh of electricity while only consuming 14.7 TWh. The natural resource base for renewable energy is high by European standards, with the core sources being wind, wave, and tidal. Wales has a long history of renewable energy: in the 1880s, the first house in Wales with electric lighting powered from its own hydro-electric power station was in Plas Tan y Bwlch, Gwynedd. In 1963, the Ffestiniog Power Station was constructed, providing a large scale generation of hydroelectricity, and in November 1973, the Centre for Alternative Technology was opened in Machynlleth.
