Energy in Uruguay describes energy and electricity production, consumption and import in Uruguay. As part of climate mitigation measures and an energy transformation, Uruguay has converted over 98% of its electrical grid to sustainable energy sources (primarily solar, wind, and hydro). [1] Fossil fuels are primarily imported into Uruguay for transportation, industrial uses and applications like domestic cooking. Four hydroelectric dams provide much of the country's energy supply.
Historically, energy has been a stronghold of state-owned companies, such as UTE and ANCAP. The National Directorate of Energy (Spanish : Dirección Nacional de Energía) is the main governmental body in charge of energy policies. [2]
The Global Economic Crisis of 2008 made many of the materials to produce renewable energy cheaper, therefore Uruguay decided it would be the best time to develop their clean energy sector, heavily investing in 2011 and 2012. This has helped increase the country's output immediately. [3] These projects are all developed by the Uruguayan Energy Policies of 2005-2030. [4]
Uruguay's renewable energies provide over 94.5% of the country’s electricity and 55% of the country's total energy mix. [5]
The electricity sector of Uruguay has traditionally been based on domestic hydropower along with thermal power plants, and reliant on imports from Argentina and Brazil at times of peak demand. Over the last 10 years, investments in renewable energy sources such as wind power and solar power allowed the country to cover in early 2016 94.5% of its electricity needs with renewable energy sources. [6]
Hydropower provides a large percentage of installed production capacity in Uruguay, almost all of it produced by four hydroelectric facilities, three on the Rio Negro and one, the Salto Grande dam shared with Argentina, on the Uruguay River. The production from these hydropower sources is dependent on seasonal rainfall patterns, but under normal hydrological conditions, can supply off-peak domestic demand.
Thermal power from petroleum fired power plants, activated during peak demand, used to provide the remaining installed production capacity. Generation from fossil fuel decreased substantially in recent years, with renewables accounting for 94.5% of electricity generation in 2015. [7] Thermal power from biomass also provides additional power generation capacity.
The shift to renewable energy sources in recent years has been achieved thanks to modernization efforts, based on legal and regulatory reforms in 1997, 2002, and 2006, which have led to large new investments in electrical production capacity including from the private sector. Purchasing agreement offered by the government in the final reform in 2006 incentivized a rapid growth of sustainable energy capacity in the country. [8] Wind power capacity has gone from negligible in 2012 to 10% of installed capacity by 2014. A new, highly efficient combined cycle power plant which can run on either gas or oil has been installed [9] .[ citation needed ] A number of photovoltaic solar power plants have been built.
Additionally, a new electrical grid interconnection has improved the ability to import or export electricity with Brazil.[ citation needed ] | This article needs to be updated. The reason given is: the energy crisis and nuclear energy debate has finished due to have been deployed along the country sources of renewable energies like wind turbines and solar photovoltaics technologies.(September 2017) |
The use of nuclear energy in Uruguay is prohibited by law 16.832 of 1997. [10] Despite this, the country has several institutions that regulate its use, such as the Center for Nuclear Research (Centro de Investigaciones Nucleares) or the National Regulation Authority on Radiological Protection (Autoridad Reguladora Nacional en Radioprotección).
Furthermore, for several years Uruguay had a small nuclear reactor for research and personnel training. It was brought from the United States in 1964 and began to work in the building of the Center for Nuclear Research in Malvin Norte in 1978. [11] It was turned off because of the detection of corrosion in 1985 and all nuclear fuel was removed. A year later, the Chernobyl and Goiânia nuclear accidents occurred. This influenced public opinion, and in 1988 —during the first presidency of Julio Maria Sanguinetti— a cooperation agreement of nuclear energy between Uruguay and Canada was signed, in which they planned the construction of a nuclear plant in the city of Paso de los Toros. [12] The announcement caused a social unrest and it was decided to open a debate on nuclear energy. [12] As a result, the Parliament did not ratify the agreement, and they passed the aforementioned law prohibiting nuclear energy in the country. [12]
The energy crisis in Uruguay in 2007 led to Uruguay reopening the nuclear debate under the presidency of Tabaré Vázquez, when the Executive Branch established a multiparty committee devoted to the study of the use of nuclear energy to generate electricity and the installation of a nuclear power plant. [13] The Fukushima accident stimulated the discussions of different scopes, especially political and social. In July 2011 the government announced that Uruguay was soon to enter Phase 1 of an evaluation of nuclear energy, [lower-alpha 1] providing 10 million Uruguayan pesos from the national budget to hire specialist advisers, consulting the population and reviewing the human resources and technology available.The electricity sector of Uruguay has traditionally been based on domestic hydropower along with thermal power plants, and reliant on imports from Argentina and Brazil at times of peak demand.

India is the third largest producer of electricity in the world. During the fiscal year (FY) 2023–24, the total electricity generation in the country was 1,949 TWh, of which 1,734 TWh was generated by utilities.
Renewable energy progress in the European Union (EU) is driven by the European Commission's 2023 revision of the Renewable Energy Directive, which raises the EU's binding renewable energy target for 2030 to at least 42.5%, up from the previous target of 32%. Effective since November 20, 2023, across all EU countries, this directive aligns with broader climate objectives, including reducing greenhouse gas emissions by at least 55% by 2030 and achieving climate neutrality by 2050. Additionally, the Energy 2020 strategy exceeded its goals, with the EU achieving a 22.1% share of renewable energy in 2020, surpassing the 20% target.
The energy policy of India is to increase the locally produced energy in India and reduce energy poverty, with more focus on developing alternative sources of energy, particularly nuclear, solar and wind energy. Net energy import dependency was 40.9% in 2021-22. The primary energy consumption in India grew by 13.3% in FY2022-23 and is the third biggest with 6% global share after China and USA. The total primary energy consumption from coal, crude oil, natural gas, nuclear energy, hydroelectricity and renewable power is 809.2 Mtoe in the calendar year 2018. In 2018, India's net imports are nearly 205.3 million tons of crude oil and its products, 26.3 Mtoe of LNG and 141.7 Mtoe coal totaling to 373.3 Mtoe of primary energy which is equal to 46.13% of total primary energy consumption. India is largely dependent on fossil fuel imports to meet its energy demands – by 2030, India's dependence on energy imports is expected to exceed 53% of the country's total energy consumption.
Brazil is the 7th largest energy consumer in the world and the largest in South America. At the same time, it is an important oil and gas producer in the region and the world's second largest ethanol fuel producer. The government agencies responsible for energy policy are the Ministry of Mines and Energy (MME), the National Council for Energy Policy (CNPE), the National Agency of Petroleum, Natural Gas and Biofuels (ANP) and the National Agency of Electricity (ANEEL). State-owned companies Petrobras and Eletrobras are the major players in Brazil's energy sector, as well as Latin America's.
For solar power, South Asia has the ideal combination of both high solar insolation and a high density of potential customers.
The electricity sector in Argentina constitutes the third largest power market in Latin America. It relies mostly on thermal generation and hydropower generation (36%). The prevailing natural gas-fired thermal generation is at risk due to the uncertainty about future gas supply.
As of August 2020 Chile had diverse sources of electric power: for the National Electric System, providing over 99% of the county's electric power, hydropower represented around 26.7% of its installed capacity, biomass 1.8%, wind power 8.8%, solar 12.1%, geothermal 0.2%, natural gas 18.9%, coal 20.3%, and petroleum-based capacity 11.3%. Prior to that time, faced with natural gas shortages, Chile began in 2007 to build its first liquefied natural gas terminal and re-gasification plant at Quintero near the capital city of Santiago to secure supply for its existing and upcoming gas-fired thermal plants. In addition, it had engaged in the construction of several new hydropower and coal-fired thermal plants. But by July 2020 91% of the new capacity under construction was of renewable power, 46.8% of the total solar and 25.6% wind, with most of the remainder hydro.
Energy in Mexico describes energy, fuel, and electricity production, consumption and import in Mexico.
Ghana generates electric power from hydropower, fossil-fuel, and renewable energy sources such as wind and solar energy. Electricity generation is one of the key factors in order to achieve the development of the Ghanaian national economy, with aggressive and rapid industrialization; Ghana's national electric energy consumption was 265 kilowatt hours per each one in 2009.
Brazil has the largest electricity sector in Latin America. Its capacity at the end of 2021 was 181,532 MW. The installed capacity grew from 11,000 MW in 1970 with an average yearly growth of 5.8% per year. Brazil has the largest capacity for water storage in the world, being dependent on hydroelectricity generation capacity, which meets over 60% of its electricity demand. The national grid runs at 60 Hz and is powered 83% from renewable sources. This dependence on hydropower makes Brazil vulnerable to power supply shortages in drought years, as was demonstrated by the 2001–2002 energy crisis.
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.

Over the last 10 years, investments in renewable energy sources such as wind power and solar power allowed the country to cover in early 2016 94.5% of its electricity needs with renewable energy sources.
The electricity sector in Switzerland relies mainly on hydroelectricity, since the Alps cover almost two-thirds of the country's land mass, providing many large mountain lakes and artificial reservoirs suited for hydro power. In addition, the water masses drained from the Swiss Alps are intensively used by run-of-the-river hydroelectricity (ROR). With 9,052 kWh per person in 2008, the country's electricity consumption is relatively high and was 22% above the European Union's average.
Estonia's electricity sector is interconnected with regional energy markets, particularly through connections with Finland, Latvia, and Russia. The direct electrical interconnection with Finland was established in 2006 and was further strengthened by the Estlink 2 interconnector in 2014. Estonia joined the Nord Pool Spot market by 2012, securing its own price area within this regional electricity market.
Primary energy consumption in Spain in 2020 was mainly composed of renewable sources. The largest sources are petroleum (42.3%), natural gas (19.8%) and coal (11.6%). The remaining 26.3% is accounted for by nuclear energy (12%) and different renewable energy sources (14.3%). Domestic production of primary energy includes nuclear (44.8%), solar, wind and geothermal (22.4%), biomass and waste (21.1%), hydropower (7.2%) and fossil (4.5%).

Renewable energy has developed rapidly in Italy over the past decade and provided the country a means of diversifying from its historical dependency on imported fuels. Solar power accounted for around 8% of the total electric production in the country in 2014, making Italy the country with the highest contribution from solar energy in the world that year. Rapid growth in the deployment of solar, wind and bio energy in recent years lead to Italy producing over 40% of its electricity from renewable sources in 2014.
Renewables supply a quarter of energy in Turkey, including heat and electricity. Some houses have rooftop solar water heating, and hot water from underground warms many spas and greenhouses. In parts of the west hot rocks are shallow enough to generate electricity as well as heat. Wind turbines, also mainly near western cities and industry, generate a tenth of Turkey’s electricity. Hydropower, mostly from dams in the east, is the only modern renewable energy which is fully exploited. Hydropower averages about a fifth of the country's electricity, but much less in drought years. Apart from wind and hydro, other renewables; such as geothermal, solar and biogas; together generated almost a tenth of Turkey’s electricity in 2022. Türkiye has ranked 5th in Europe and 12th in the world in terms of installed capacity in renewable energy. The share of renewables in Türkiye’s installed power reached to 54% at the end of 2022.
The electricity sector of Armenia includes several companies engaged in electricity generation and distribution. Generation is carried out by multiple companies both state-owned and private. In 2020 less than a quarter of energy in Armenia was electricity.
