There are currently over 2,200 hydroelectric power stations in Japan, hydroelectricity being the main form of power generation in Japan until the 1970s. Many of these power stations are “pumped energy storage” stations.
The Okinawa Yanbaru Seawater Pumped Storage Power Station (沖縄やんばる海水揚水発電所, Okinawa Yanbaru Kaisui Yōsui Hatsudensho) was an experimental hydroelectric power station located in Kunigami, Okinawa, Japan and operated by the Electric Power Development Company. It was the world’s first pumped-storage facility to use seawater for storing energy.
The large capacity of pumped storage hydropower was built to store energy from nuclear power plants, which until the Fukushima disaster constituted a large part of Japan electricity generation. As of 2015, Japan is the country with the highest capacity of pumped-storage hydroelectricity in the world, with 26 GW of power installed.
Pumped storage type power plants have been developed in Japan since 1930. Tokyo Electric Power Co., Inc. (TEPCO) has 9 pumped storage power plants with approximately 10,000 MW in total, including one under construction.
Many of these power stations are “pumped energy storage” stations. Pumped hydro energy storage generates electricity by pumping water from a lower reservoir to an upper reservoir and using this water to generate power when needed.
Mixed pumped storage hydroelectric power plants are pondage type hydroelectric power plants added with pumped storage power generation systems to enable them to make large-scale daily adjustments to meet peak demand.

The Cabinet, as the executive branch of the North Korean state, is responsible for implementing the state's economic policies, as guided by the Workers' Party. The cabinet is not responsible for defense and security issues, as those are handled by the State Affairs Commission.
Preface North Korea suffers from chronic energy shortages. Rolling blackouts are common, even in the nation’s capital, while some of the poorest citizens receive state-provided electricity only once a year.
Under North Korea’s two-tier energy system, which prioritises industrial facilities, the only way for many citizens to access electricity is to pay state functionaries to allow them to install cables to siphon off power from local factories.
According to Statistics Korea, a South Korean government body, North Korea’s total power generation capacity in 2021 was 8,225 megawatts. The equivalent figure for South Korea, which has a population approximately twice that of the North, was 134,000MW.
Jeong-hyeon, a North Korean escapee, told the Financial Times that many residents in Hamhung, the second-most populous city, “relied on a solar panel, a battery and a power generator to light their houses and power their television”. But solar power is still only a partial solution to the country’s energy woes.
Rosatom, Russia’s state-owned nuclear energy company, is the world’s largest exporter of nuclear reactors. If given a political opening, it has suggested Rosatom could build a nuclear power plant in North Korea in 6–7 years —a proposal that would benefit Russia commercially while undermining regional stability.

Energy in Benin has a diverse energy mix and takes several forms including: solar, wind, hydropower, biomass, fossil resources, and mineral resources. Out of this energy mix, about 60% of energy comes from biomass. Benin is also dependent on energy imports from Ghana and Côte d'Ivoire.
This section provides information on Benin’s current energy situation with energy demand-and-supply scenarios. According to the International Renewable Energy Agency (IRENA), 41% of Benin’s population currently have access to electricity.
Benin belongs to several institutions like West Africa (WA), the African Union (AU), the World Trade Organization (WTO), ECOWAS, and WAEMU, and has a total installed energy capacity at 349 MW, with estimated electricity needs at 600 MW, given rapidly growing electricity demand, according to the West African Development Bank (BOAD, 2019) .
Traditional biomass – the burning of charcoal, crop waste, and other organic matter – is not included. This can be an important energy source in lower-income settings. Benin: How much of the country’s energy comes from nuclear power? Nuclear energy – alongside renewables – is a low-carbon energy source.
The Ouémé River, the largest river in Benin, was estimated to be able to house around ten hydropower plants with power ratings ranging between 10 MW and 160 MW.
Benin has also joined this dynamic by considerably increasing its green energy production efforts in recent years. The country has a huge undeveloped renewable-energy (RE) potential that can contribute considerably to its national energy production capacity. This paper summarizes the current RE situation in Benin and examines its future prospects.
