TWh in the context of Hour

Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, 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.

Construction of a hydroelectric complex can have significant environmental impact, principally in loss of arable land and population displacement. They also disrupt the natural ecology of the river involved, affecting habitats and ecosystems, and siltation and erosion patterns. While dams can ameliorate the risks of flooding, dam failure can be catastrophic.

The Three Gorges Dam, officially known as Yangtze River Three Gorges Water Conservancy Project is a hydroelectric gravity dam that spans the Yangtze River near Sandouping in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The world's largest power station by installed capacity (22,500 MW), the Three Gorges Dam generates 95±20 TWh of electricity per year on average, depending on the amount of precipitation in the river basin. After the monsoons of 2020, the dam produced nearly 112 TWh in a year, breaking the record of 103 TWh set by the Itaipu Dam in 2016.

The dam's body, 185 meters high and 2,309 meters wide, was completed in 2006. The power plant became fully operational in 2012, when the last of the 32 main water turbines in the underground plant began production. The last major component of the project, the ship lift, was completed in 2015.

Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation.Today, wind power is generated almost completely using wind turbines, generally grouped into wind farms and connected to the electrical grid.

In 2024, wind supplied about 2,500 TWh of electricity, which was over 8% of world electricity. With about 100 GW added during 2021, mostly in China and the United States, global installed wind power capacity exceeded 800 GW. 30 countries generated more than a tenth of their electricity from wind power in 2024 and wind generation has nearly tripled since 2015. To help meet the Paris Agreement goals to limit climate change, analysts say it should expand much faster – by over 1% of electricity generation per year.

In 2019, the total energy production in Indonesia is 450.79 million tonnes of oil equivalent, with a total primary energy supply of 231.14 million tonnes of oil equivalent and electricity final consumption of 263.32 terawatt-hours. From 2000 to 2021, Indonesia's total energy supply increased by nearly 60%.

The Leibstadt Nuclear Power Plant (German: Kernkraftwerk Leibstadt, KKL) is located near Leibstadt, canton of Aargau, Switzerland, on the Rhine and close to the border with Germany. Commissioned in 1984, it is the youngest and most powerful of the country's four operating reactors.

Its General Electric-built boiling water reactor produces 1,220 MW of electrical power. The nuclear power station has produced approximately 8.5 TWh per year, slightly less than the Goesgen Nuclear Power Plant.

Petroleum production in Canada is a major industry which is important to the overall economy of North America. Canada has the third largest oil reserves in the world and is the world's fourth largest oil producer and fourth largest oil exporter. In 2019 it produced an average of 750,000 cubic metres per day (4.7 Mbbl/d) of crude oil and equivalent. Of that amount, 64% was upgraded from unconventional oil sands, and the remainder light crude oil, heavy crude oil and natural-gas condensate. Most of the Canadian petroleum production is exported, approximately 600,000 cubic metres per day (3.8 Mbbl/d) in 2019, with 98% of the exports going to the United States. Canada is by far the largest single source of oil imports to the United States, providing 43% of US crude oil imports in 2015.

The petroleum industry in Canada is also referred to as the "Canadian Oil Patch"; the term refers especially to upstream operations (exploration and production of oil and gas), and to a lesser degree to downstream operations (refining, distribution, and selling of oil and gas products). In 2005, almost 25,000 new oil wells were spudded (drilled) in Canada. Daily, over 100 new wells are spudded in the province of Alberta alone. Although Canada is one of the largest oil producers and exporters in the world, it also imports significant amounts of oil into its eastern provinces since its oil pipelines do not extend all the way across the country and many of its oil refineries cannot handle the types of oil its oil fields produce. In 2017 Canada imported 405,700 bbl/day (barrels per day) and exported 1,115,000 bbl/day of refined petroleum products.

As of 2023, Europe had a total installed wind capacity of 255 gigawatts (GW). In 2017, a total of 15,680 MW of wind power was installed, representing 55% of all new power capacity, and the wind power generated 336 TWh of electricity, enough to supply 11.6% of the EU's electricity consumption.

In Q4 2023, wind power exceeded coal in European electricity generation for the first time, generating 193 TWh compared to coal's 184 TWh. Despite wind installation challenges, wind generation rose by 20% from 2022. New policies aim to further boost wind power in 2024.
