Energy Conversion Devices, Inc. (ECD) was an American photovoltaics manufacturer of thin-film solar cells made of amorphous silicon used in flexible laminates and in building-integrated photovoltaics.

Renewable energy (also called green energy) is energy made from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, bioenergy/biomass, and hydropower.

Agrivoltaics (also called agrophotovoltaics, agrisolar, or dual-use solar) refers to the practice of using the same land for both solar energy and agriculture. There are a range of approaches.

Renewable energy in Germany comes mainly from wind power, solar power and biomass and is a central component of the country's Energiewende. In 2025, renewable sources accounted for 23.8% of Germany's gross final energy consumption.

SolarCity Corporation was a publicly traded company headquartered in Fremont, California, that sold and installed solar energy generation systems as well as other related products and services to residential, commercial, and industrial customers. The company was founded on July 4, 2006, by Peter and Lyndon Rive, the…

A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by using the photovoltaic effect. It is a type of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is…

An energy crisis from 2021 to 2023 began in the aftermath of the COVID-19 pandemic, resulting in shortages and increased prices in oil, gas and electricity markets. The crisis was particularly acute in Europe, and especially following the Russian invasion of Ukraine, the energy crisis became popularly associated with…

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.

Renewable energy developed rapidly in Italy between 2005 and 2023, nearly doubling, and provided the country with a means of diversifying from its historical dependency on imported fuels. Solar power accounted for around 17% of the total electric production in the country in 2025.

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,…
