Renewable energy in Australia
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 .
Grid energy storage
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,…
Variable renewable energy
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…
Renewable energy in California

Solar power in China
China is the largest market in the world for both photovoltaics (PV) and solar thermal energy. Its PV capacity crossed 1,000 gigawatts (one terawatt, 1 TW) in May 2025.
Copper in renewable energy
Renewable energy sources such as solar, wind, tidal, hydro, biomass, and geothermal have become significant sectors of the energy market. The rapid growth of these sources in the 21st century has been prompted by the increasing costs and environmental impact of fossil fuels, which has led to a proposed phase out of…
Economics of nuclear power
The economics of nuclear power concerns the costs, financial risks, and economic factors involved in generating electricity from nuclear reactors, including the capital required to build plants, the operating and fuel costs over their lifetime, and the expenses of decommissioning and managing radioactive waste. It…
