However some countries, such as South Korea and Japan, use land for agriculture under PV, [108] [109] or floating solar, [110] together with other low-carbon power sources. [111] [112] Worldwide land use has minimal ecological impact. [113] Land use can be reduced to the level of gas power by installing on buildings and other built up areas. [104]
It occupies less land area per kilowatt-hour (kWh) of electricity generated than any other energy conversion system, apart from rooftop solar energy, and is compatible with grazing and crops. It generates the energy used in its construction in just 3 months of operation, yet its operational lifetime is 20–25 years.
Projects to spread electricity create a wealth of job opportunities and help to alleviate poverty. For example, India set a target of 175GW of clean energy to be installed by 2022 to increase electrification throughout the country.
