The developing nations of Africa are popular locations for the application of renewable energy technology. Currently, many nations already have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural populations.

Policy makers often debate the constraints and opportunities of renewable energy. Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent.

Vietnam utilizes four main sources of renewable energy: hydroelectricity, wind power, solar power and biomass. At the end of 2018, hydropower was the largest source of renewable energy, contributing about 40% to the total national electricity capacity.

Lodestone Energy Limited is a New Zealand electricity generation and retail company that specialises in the construction and operation of photovoltaic power stations. As of August 2026, it operates five solar farms, with one more under construction.

The use of solar energy began in Israel in the 1950s with the development by Levi Yissar of a solar water heater to address the energy shortages that plagued the new country. By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold.

Energy subsidies are government payments that keep the price of energy lower than market rate for consumers or higher than market rate for producers. These subsidies are part of the energy policy of the United States.

Variable renewable energy (VRE) or intermittent renewable energy sources (IRES) are renewable energy sources that are not dispatchable (adjustable on demand) due to their fluctuating nature, such as wind power and solar power, as opposed to controllable renewable energy sources, such as dammed hydroelectricity or…

Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power,…

Renewable energy in Australia is based mainly on biomass, solar, wind, and hydro generation technologies. Over a third of all electricity generated in Australia is now from renewable sources, a proportion that is increasing in line with global trends .

Renewable energy in Spain, consisting of bioenergy, wind, solar, and hydro sources, accounted for 25.0% of the Total Energy Supply (TES) in 2023. In the same year, the share of electricity generated from renewable sources reached 50.3%, reflecting the country's progress towards its decarbonisation goals.
