The Human Rights Measurement Initiative (HRMI) finds that Sao Tome and Principe is fulfilling only 83.8% of its expected commitments to the right to education based on the country's level of income. HRMI breaks down the right to education by looking at the rights to both primary education and secondary education.
Tertiary institutions are the National Lyceum and the University of São Tomé and Príncipe. São Toméan culture is a mixture of African and Portuguese influences. São Toméans are known for ússua and socopé rhythms, while Príncipe is home to the dêxa beat.
After independence, control of these plantations passed to various state-owned agricultural enterprises. The main crop on São Tomé is cocoa, representing about 95% of agricultural exports. Other export crops include copra, palm kernels, and coffee.

Grid energy storage (also called large-scale energy storage) is a collection of methods used for on a large scale within an . Electrical energy is stored during times when electricity is plentiful and inexpensive (especially from sources such as and ) or when demand is low, and later returned to the grid. Energy storage for the electrical grid is about to hit the big time. By the reckoning of the International Energy Agency (iea), a forecaster, grid-scale storage is now the fastest-growing of all .

Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
In an electrical grid without energy storage, generation that relies on energy stored within fuels (coal, biomass, natural gas, nuclear) must be scaled up and down to match the rise and fall of electrical production from intermittent sources (see load following power plant).
Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.
Two forms of storage are suited for seasonal storage: green hydrogen, produced via electrolysis and thermal energy storage (such as pumped thermal energy storage for electricity). As the round-trip efficiency is low, significant hydrogen needs to be stored. Energy storage is one option to making grids more flexible.
Generally speaking, energy storage is economical when the marginal cost of electricity varies more than the costs of storing and retrieving the energy plus the price of energy lost in the process.
