Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4,500 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.
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.
The Hub Power Company Limited, colloquially known as Hubco, is a Pakistani power company based in Karachi, Sindh. It was the first independent power producer (IPP) to establish in Pakistan and as of 2024 is the largest IPP with a combined installed power generation capacity of 3,581 MW. The revenue of the company is United States Dollars denominated.
Wind power became a significant energy source within South Australia over the first two decades of the 21st century. In 2015, there was an installed capacity of 1,475 MW, which accounted for 34% of electricity production in the state. This accounted for 35% of Australia's installed wind power capacity. In 2021, there was an installed capacity of 2052.95 MW, which accounted for 42.1% of the electricity production in the state in 2020.
Wind power in California had initiative and early development during Governor Jerry Brown's first two terms in the late 1970s and early 1980s. The state's wind power capacity has grown by nearly 350% since 2001, when it was less than 1,700 MW. In 2016, wind energy supplied about 6.9% of California's total electricity needs, or enough to power more than 1.3 million households. Most of California's wind generation is found in the Tehachapi area of Kern County, California, with some large projects in Solano, Contra Costa and Riverside counties as well. California is among the states with the largest amount of installed wind power capacity. In recent years, California has lagged behind other states when it comes to the installation of wind power. It was ranked 4th overall for wind power electrical generation at the end of 2016 behind Texas, Iowa, and Oklahoma. As of 2019, California had 5,973 megawatts (MW) of wind power generating capacity installed.
Musselroe Wind Farm is a wind farm at Cape Portland, Tasmania, Australia. It was the third wind farm built in the state, following the Bluff Point and Studland Bay Wind Farms.
The Zorlu Energy Power Project is a wind farm located at Jhimpir in Thatta District of Sindh province in Pakistan, 120 kilometres north-east of Karachi. The project has been developed by Zorlu Energy Pakistan, a subsidiary of the Turkish firm Zorlu Enerji. The total cost of project is $143 million.
Jhimpir is a village in Thatta District, Sindh, Pakistan. It is situated 114 km away from Karachi. It is the site of Pakistan's first wind power project. However, Jhimpir has a railway station and train service is available for Karachi and upcountry from here.
Renewable energy in Pakistan is a relatively underdeveloped sector; however, in recent years, there has been more and more interest to explore renewable energy resources for the energy production. Around 10.57% of Pakistan’s total installed power generation capacity comes renewables. Most of Pakistan's renewable energy comes from hydroelectricity. As per the vision of the Prime Minister, there is the aim to “induct 20% of RE by the year 2025 and 30% of RE by the year 2030.”
The following outline is provided as an overview of and topical guide to wind energy:
Renewable energy in Taiwan contributed to 8.7% of national electricity generation as of end of 2013. The total installed capacity of renewable energy in Taiwan by the end of 2013 was 3.76 GW.
The Quaid-e-Azam Solar Park is a photovoltaic power station in Bahawalpur, Punjab, Pakistan, named in honor of Quaid-e-Azam Muhammad Ali Jinnah, the Founder of Pakistan. It is a 400 MW solar facility spanning an area of 8 km2 and hosting 1.6 million solar modules. The initial phase of the project was constructed by the Government of Punjab through a 100% owned subsidiary QA Solar in May 2015 at a cost of $131 million. On 5 May 2015, the then Prime Minister of Pakistan Nawaz Sharif inaugurated the first 100 MW project and dedicated it to the nation. Subsequent expansion was done in public-private partnership with Appolo Solar Development Pakistan Limited, Best Green Energy Pakistan Limited and Crest Energy Pakistan Limited each installing a 100 MW unit. The next phase of 100 MW will be installed by Zorlu Solar Pakistan (Pvt.) Limited, making it a 500 MW facility. Total planned capacity of the solar park is 1,000 MW.
SK Hydro also known as Suki Kinari HPP, is an under-construction, run-of-the-river hydropower project located on the Kunhar river in the Kaghan valley of Mansehra District Khyber Pakhtunkhwa, which has an installed generation capacity of 884 MW.
The Engro Thar Coal Power Project (Thar-ll), also known as Engro Powergen Thar, is a coal-fired power plant developed as part of the China–Pakistan Economic Corridor by Sindh Engro Coal Mining Company and China Machinery Engineering Corporation in the Thar Block-II of the Thar Coalfield, Tharparkar District, Sindh, Pakistan 25 kilometers from the town of Islamkot near the village of Singharo-Bitra.
The HydroChina Dawood Wind Power Project is a wind farm which was developed as part of the China–Pakistan Economic Corridor's Early Harvest energy projects on 1,720 acres of tidal flats is located in Gharo, Sindh – approximately 80 kilometers east of Karachi. It is being developed by the Chinese firm HydroChina, and is expected to provide electricity to the Pakistani grid by August 2016.
The Formosa 1 Offshore Wind Farm is a 128 MW offshore wind power station in Miaoli County, Taiwan. It is Taiwan's first offshore wind farm.
Kidston Solar Project is a photovoltaic solar power station built on top of the former Kidston Gold Mine utilising the tailings storage facility in northern Queensland, Australia. The project consists of two solar farms, KS1 and KS2. The Kidston Solar Project is the first of four projects that comprise the Kidston Clean Energy Hub also occupying this area. A 250 megawatt (MW) hydro-pumped storage power generation project and a 150 MW wind farm make up the third and forth components. The site is located close to an existing substation and transmission line.
