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,…
Financial incentives for photovoltaics
Financial incentives for photovoltaics are incentives offered to electricity consumers to install and operate solar-electric generating systems, also known as photovoltaics (PV). Governments offered incentives in order to encourage the PV industry to achieve the economies of scale needed to compete where the cost of…
Net metering
Net metering (or net energy metering, NEM) is an electricity billing mechanism that allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with renewable energy sources like wind and solar, which are…
Tesla Model 3
The Tesla Model 3 is a battery electric powered mid-size sedan with a fastback body style built by Tesla, Inc., introduced in 2017. The Model 3 was marketed as a more affordable option compared to Tesla's previous vehicles, the Model S and Model X. The Model 3 was the world's top-selling plug-in electric car for three…
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…
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…
Renewable portfolio standards in the United States
A Renewable Portfolio Standard (RPS) is a regulation that requires the increased production of energy from renewable energy sources, such as wind, solar, biomass, and geothermal, which have been adopted in 38 of 50 U.S. states and the District of Columbia. The United States federal RPS is called the Renewable…
Pradhan Mantri Bharatiya Janaushadhi Pariyojana
Pradhan Mantri Bharatiya Janaushadhi Pariyojana (PMBJP) (transl. Prime Minister’s Indian Public Medicine Scheme) is a campaign and public welfare scheme of the Government of India, launched in 2008 as the Jan Aushadhi Scheme by the Ministry of Chemicals and Fertilizers. The initiative was rebranded in 2016 as the…
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…
Net metering in the United States
Net metering is a policy by many states in the United States designed to help the adoption of renewable energy. Net metering was pioneered in the United States as a way to allow solar and wind to provide electricity whenever available and allow use of that electricity whenever it was needed, beginning with utilities…
