Solar power by country
Many countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies: Photovoltaic (PV) systems use solar panels, either on rooftops or in ground-mounted solar…
Gautrain
Gautrain is an 80-kilometre (50-mile) higher-speed express commuter rail system in Gauteng, South Africa, which links Johannesburg, Pretoria, Kempton Park and O. R. Tambo International Airport. It takes 15 minutes to travel from Sandton to O. R. Tambo International Airport on the Gautrain and 35 minutes from Pretoria…
Criticism of Amazon

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors.
Denver Federal Center
The Denver Federal Center, in Lakewood, Colorado, is part of the General Services Administration (GSA) and is home to about 6,200 employees of agencies of the federal government of the United States. The center encompasses an area of about 670 acres (2.7 km2) and has 90 buildings with over 4 000 000 square feet (370…
List of photovoltaics companies
This is a list of notable photovoltaics (PV) companies. Grid-connected solar photovoltaics (PV) is the fastest growing energy technology in the world, growing from a cumulative installed capacity of 7.7 GW in 2007, to 320 GW in 2016.
Growth of photovoltaics
Starting in 1992, the worldwide usage of photovoltaics (PV) increased exponentially. During this period, it evolved from a niche market of small-scale applications to a mainstream electricity source.
Building-integrated photovoltaics
Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or façades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of…
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…
