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.
Energy policy of Canada
Canada has access to all main sources of energy including oil and gas, coal, hydropower, biomass, solar, geothermal, wind, marine and nuclear. It is the world's second largest producer of uranium, third largest producer of hydro-electricity, fifth largest natural gas producer, and the fifth largest producer of crude…
Solar power in the United Arab Emirates
While being a major oil producing country, the United Arab Emirates (UAE) has taken steps to introduce solar power on a large scale. However, solar power still accounts for a small share of energy production in the country.
Solar cell research
There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing…
Wind power in Scotland
Wind power is the fastest-growing renewable energy technology in Scotland, with 17.7 gigawatts (GW) of installed wind power capacity by Q2 2025. This included 10.4 GW from onshore wind in Scotland and 4.3 GW of offshore wind generators.
Fekola Hybrid Power Station
The Fekola Hybrid Power Station (French Centrale électrique hybride de Fekola) is a 115 MW (154,000 hp) power plant in Mali. The power system comprises 68 MW of thermal energy, 30 MW of solar power and 17.3 MW of lithium ion battery energy storage.
Passive solar building design
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of…
Solar cell
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…

SolaX Power Network Technology (Zhejiang) Co., Ltd. (Chinese: 艾罗能源), commonly known as SolaX Power or SolaX, is a Chinese manufacturer of solar inverters and energy-storage products headquartered in Hangzhou, Zhejiang.
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…
