Typically, the carbon footprint of hydroelectricity is only 24 gCo2/KWh whereas the carbon footprint of Coal fired power plant is much larger, 820 gCO2/KWh.
In 2015, hydroelectricity was only 16.6 % of the global energy demands. for 7.4 billion people living in this world, this energy is equivalent to 1.47 KWh/person/day which is tantamount to 0.5 human unit only. The share of hydroelectricity is considered to rise up to 25% of the global energy share.
Energy density calculation in hydropower design
Suppose, in a suitable land for hydropower development has the rain gauge reading of 500 mm/ year.
Rain= 500 mm/year
Rain= 0.5m^3/m^2/ year= 0.5*1000*10
= 500 kg/m^2/year
Potential energy of water Epot= mgh
=500*9.8*100 (h=100)
=490n Kj
Epot= 490*9.8*100
=0.14 KWh/m^2
Including losses, evaporation, and leakage, only 20% energy from hydropower dam is used for voting.
