List of Hungarian hydroelectric dams
Hydroelectricity is not prevalent in Hungary due to unsuitable geographical conditions and civil resentment. The country's capacity of hydroelectricity was 57 MWs in 2015. [1]
Hungary's greatest hydroelectric project was the Gabčíkovo–Nagymaros Dams. The complex was built together with Czechoslovakia, but cancelled after the fall of Communism in Hungary. Slovakia finished the modified version of the project, unilaterally. The ICJ ruled in the legal dispute between the two countries, but the practical problems arising from the functioning of the dam are still unsettled. [2]
Due to the environmental concerns of the Hungarian society, no major hydroelectric projects are supported by the government. However, plans exist to create new dams on the Danube to make the river more suitable for navigation. [3]
Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. Precise definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), "micro" (<100 kW), "pico" (<10 kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the Three Gorges Dam at 22,500 megawatts or the vast multiple projects of the Tennessee Valley Authority.
Hydroelectricity is electricity produced from hydropower. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was expected to increase by about 3.1% each year for the next 25 years.
Dams and reservoirs in Laos are the cornerstone of the Lao government's goal of becoming the "battery of Asia".
The Dez Dam, formerly known as Mohammad Reza Shah Pahlavi Dam before 1979 Revolution, is an arch dam on the Dez River in the southwestern province of Khuzestan, Iran. It is about 15 km of andimeshk city. It was built between 1959 and 1963 under the rule of Mohammad Reza Pahlavi, the last Shah of Iran, with contacting an Italian consortium and is owned by the Khuzestan Water & Power Authority. The dam is 203 metres (666 ft) high, making it one of the highest in the country, and has a reservoir capacity of 3,340,000,000 m3 (2,710,000 acre⋅ft). At the time of construction the Dez Dam was Iran's biggest development project. The primary purpose of the dam is hydroelectric power production and irrigation. It has an associated 520 MW power station and its reservoir helps irrigate up to 80,500 ha of farmland. US$42 million of the cost to construct the dam came from the World Bank.
The Gabčíkovo–Nagymaros Dams is a large barrage project on the Danube. It was initiated by the Budapest Treaty of 16 September 1977 between the Czechoslovak Socialist Republic and the People's Republic of Hungary. The project aimed at preventing catastrophic floods, improving river navigability and producing clean electricity.
Himachal Pradesh is extremely rich in its hydroelectricity resources. The state has about twenty five percent of the national potential. About 27,436 MW of hydroelectric power can be generated in the state by the construction of various hydroelectric projects on the five perennial river basins. Out of total hydroelectric potential of the state, 10,519 MW is harnessed so far, out of which only 7.6% is under the control of Himachal Pradesh Government while the rest is exploited by the Central Government. The state government has been giving the highest priority for its development, since hydroelectric generation can meet the growing need of power for industry, agriculture and rural electrification. It is also the biggest source of income to the state as it provides electricity to other states.
The Tokuyama Dam is an embankment dam near Ibigawa, Ibi District, Gifu Prefecture in Japan. The dam was completed in 2008 and will support a 153 MW hydroelectric power station that is expected to be fully operational in 2015. Currently, Unit 1 at 23 MW was commissioned in May 2014. The dam was originally intended to withhold the upper reservoir of a 400 MW pumped-storage power station until a design change in 2004. The dam is also intended for flood control and water supply. It is the largest dam by structural volume in Japan and withholds the country's largest reservoir by volume as well.
The Iron Gate I Hydroelectric Power Station is the largest dam on the Danube river and one of the largest hydro power plants in Europe. It is located on the Iron Gate gorge, between Romania and Serbia.
Canada is the world's third largest producer of hydroelectricity after China and Brazil. In 2014, Canada consumed the equivalent of 85.7 megatonnes worth of oil of hydroelectricity, 9.8% of worldwide hydroelectric consumption. Furthermore, hydroelectricity accounted for 25.7% of Canada's total energy consumption. It is the third-most consumed energy in Canada behind oil and natural gas.
The Mingachevir Dam is the largest hydroelectric power station in the South Caucasus, is located over Kur river and not far from Mingachevir city.
Renewable energy in Russia mainly consists of hydroelectric energy. The country is the sixth largest producer of renewable energy in the world, although it is 56th when hydroelectric energy is not taken into account. Some 179 TWh of Russia's energy production comes from renewable energy sources, out of a total economically feasible potential of 1823 TWh. 16% of Russia's electricity is generated from hydropower, and less than 1% is generated from all other renewable energy sources combined. Roughly 68% of Russia's electricity is generated from thermal power and 16% from nuclear power.
The Koldam Hydropower Station commonly known as Koldam, is an embankment dam on the Satluj River upstream of the Dehar Power House. It is 18 km from Bilaspur off the Chandigarh-Manali Highway (NH-21) near Barmana, Himachal Pradesh. The main purpose of the dam is hydroelectric power generation and it will support an 800 MW power station. The dam was constructed by National Thermal Power Corporation (NTPC).
The Çetin Dam hydropower dam, currently being constructed on the Botan River in Siirt Province, Turkey, with an installed capacity of 420 MW. It is expected to complete by 2020.
The Broadlands Dam is a 35 MW run-of-the-river hydroelectric complex currently under construction in Kitulgala, Sri Lanka. The project is expected to be completed in 2020, and will consist of two dams, and a power station further downstream.
China International Water & Electric Corporation is a Chinese construction and engineering consulting company that is a subsidiary of China Three Gorges Corporation (CTE). CWE specializes in the construction of water and hydropower projects but its work runs the gamut including road and bridge, power transmission, drainage and sewage treatment systems, dredging, port maintenance, and interior design.
Hungary is a member of the European Union and thus takes part in the EU strategy to increase its share of renewable energy. The EU has adopted the 2009 Renewable Energy Directive, which included a 20% renewable energy target by 2020 for the EU. By 2030 wind should produce in average 26-35% of the EU's electricity and save Europe €56 billion a year in avoided fuel costs. The national authors of Hungary forecast is 14.7% renewables in gross energy consumption by 2020, exceeding their 13% binding target by 1.7 percentage points. Hungary is the EU country with the smallest forecast penetration of renewables of the electricity demand in 2020, namely only 11%.
Renewable energy in Costa Rica supplied about 98.1% of the electrical energy output for the entire nation in 2016. Fossil fuel energy consumption in Costa Rica was 49.48 as of 2014, with demand for oil increasing in recent years. In 2014, 99% of its electrical energy was derived from renewable energy sources, about 80% of which from hydroelectric power. For the first 75 days of 2015, 100% of its electrical energy was derived from renewable energy sources and in mid 2016 that feat was accomplished for 110 consecutive days despite suboptimal weather conditions. As a country, Costa Rica has a geographic advantage over others in that its high concentration per capita of rivers, dams, and volcanoes allows for a high renewable energy output. In addition, Costa Rica is the fourth highest nation in terms of rainfall per capita: it receives an average of 2,926 mm of precipitation per year. As a smaller nation with a population of only 5 million and no major industry, the need for strong energy infrastructure is less than for larger countries of higher population density. The 1948 elimination of the military of Costa Rica freed up millions of dollars from the government defense budget which are now invested in social programs and renewable energy generation. As president of Costa Rica in 1948, José Figueres announced that the nation's former military budget would be refocused specifically in healthcare, education, and environmental protection.
Renewable energy in South Africa is energy generated in South Africa from renewable resources, those that naturally replenish themselves—such as sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas: electricity generation, air and water heating/cooling, transportation, and rural energy services. The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy. South Africa's contribution to greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.
