Renewable energy in Tuvalu

OverviewTuvalu''s carbon footprintTuvalu Energy Sector Development Project (ESDP)Commitment under the Majuro Declaration 2013Commitment under the United Nations Framework Convention on Climate Change (UNFCCC) 1994Solar energyWind energyFilmography

Renewable energy in Tuvalu is a growing sector of the country''s energy supply. Tuvalu has committed to sourcing 100% of its electricity from renewable energy. This is considered possible because of the small size of the population of Tuvalu and its abundant solar energy resources due to its tropical location. It is somewhat complicated because Tuvalu consists of nine inhabited islands. The Tuvalu National Energy Policy (TNEP) was formulated in 2009, and the Energy Str

Is it again time for the flywheel-based energy storage systems?

A brief background: the underlying principle of the flywheel energy storage system—often called the FES system or FESS—is a long-established basic physics. Use the available energy to spin up a rotor wheel (gyro) via a motor/generator (M/G), which stores the energy in the rotating mass (Figure 1). Electronics is also required for the motor
