California produces more renewable energy than any other state in the United States except Texas. In 2018, California ranked first in the nation as a producer of electricity from solar, geothermal, and biomass resources and fourth in the nation in conventional hydroelectric power generation.

O.Y. Nofar Energy Ltd., commonly known as Nofar Energy (Hebrew: ע.י. נופר אנרג'י בע"מ), is an Israeli renewable energy company headquartered in Kfar Saba.

The Energiewende (German for 'energy turnaround') (pronounced [ʔenɐˈɡiːˌvɛndə] ) is the ongoing energy transition by Germany. The new system intends to rely heavily on renewable energy (particularly wind, photovoltaics, and hydroelectricity), energy efficiency, and energy demand management.

A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources…

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. A long conductor used to facilitate such movement is called a transmission line.

World energy resources are the estimated maximum capacity for energy production given all available resources on Earth. They can be divided by type into fossil fuel, nuclear fuel and renewable resources.

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…

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of fossil fuel-derived, nuclear, and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.

The electricity sector in New Zealand uses almost entirely renewable energy, such as hydropower, geothermal power and increasingly wind energy. In the fourth quarter of 2025, the country generated 96.4% of its electricity from renewable sources.

Energy engineering is a multidisciplinary field of engineering that focuses on optimizing energy systems, developing renewable energy technologies, and improving energy efficiency to meet the world's growing demand for energy in a sustainable manner. It encompasses areas such as energy harvesting and storage, energy…
