Attribution: IEA In 2021, a person on Earth produces 4.19 tonnes of CO2 on an annual basis according to IEA's 2021 Global energy-related CO2 emissions and worldometer's Current World Population 7,867,479,237 People on 20210523.  In order to limit global warming to 2°C, the average level of CO2 emission per capita must not exceed 2.1 tonnes by 2050.  Comparing the energy production methods ranging from Windpower, Nuclear power, Solar power, Gas-fired Power, to Coal-fired power, Windpower emitted the fewest CO2, one of the main two anthropogenic greenhouse gases.  Attribution: energuide.be The global wind industry installed 93 GW of new capacity in 2020 that brought total global wind power capacity up to 743 GW and helped the world to avoid over 1.1 billion tonnes of CO2 annually. Since the world's first offshore wind farm was constructed in Vindeby, Denmark in 1991, offshore wind power has been recognized as one of the world's most promising forms of green energy....

How does beautiful Sunlight generate clean electricity?

Sun is one of the best energy sources for the Earth.  Sunlight carries broad wavelengths of light from UV-C (200 nm ~ 280 nm), UV-B (280 nm ~320 nm), UV-A (320 nm ~ 400 nm),  Violet (400 nm ~ 430 nm), Blue (430 nm ~490 nm),  Green (490 nm ~ 575 nm), Yellow ( 575 nm ~ 590 nm),  Orange (590 nm ~ 620 nm), Red (620 nm ~ 700 nm), NIR (700 nm ~2,500 nm), MIR (2,500 nm ~ 25,000 nm), FIR (25,000 nm ~ 1,000,000 nm)   As soon as Sunlight reaches the Earth, Photovoltaic Panels start harvesting Sunlight and converting Sunlight Energy to DC Power.  DC Power flows thru string to Solar Inverter.   Solar Inverter inverts DC Power to AC Power.  AC Power can be used by home appliances or can be fed into Utility Grid.  There are two key components in a Photovoltaic system, one is Solar Inverter, and the other is Photovoltaic Panel.  Solar Inverter has three common types:  1.  String Inverter: Most conventional inverter, which limits the...
