Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2024, no device has reached net power, although net positive reactions have been achieved.

The UK claimed that it had gotten fusion first in 1957 on ZETA, but this claim had to later be withdrawn.
Magnetic mirrors suffered from end losses, requiring high power, complex magnetic designs, such as the baseball coil pictured here.
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage, using for example, the pumped-storage method.

Wind turbines usually provide electrical generation in conjunction with other methods of producing power.
Large dams, such as Hoover Dam in the United States, can provide large amounts of hydroelectric power. It has an installed capacity of 2.07 GW.
