In 2007, Tuvalu was getting 2% of its energy from solar, through 400 small systems managed by the Tuvalu Solar Electric Co-operative Society. These were installed beginning in 1984 and, in the late 1990s, 34% of families in the outer islands had a PV system (which generally powered 1-3 lights and perhaps a few hours a day of radio use). Each of the eight islands had a medical cente.

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of used by for . A PSH system stores energy in the form of of water, pumped from a lower elevation to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through

Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel. Whi. Main componentsA typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles. .
In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have.

As countries trend away from fossil fuel-fired base load plants and towards renewable but such as wind and solar, there is a corresponding increase in the need for systems, as renewable alternatives to building more peaking or load following power plants. Another option is broader distribution of generating capacity, through the use of grid interties, such as the .
