What is hydropower in relation to green buildings?

Hydroelectric (hydroelectric) energy is classified as renewable energy because it depends on the kinetic energy of the Earth's natural water cycle to be generated. The manufacture of concrete and steel for hydroelectric dams requires equipment that can produce emissions. If fossil fuels are the energy sources for manufacturing these materials, then equipment emissions could be associated with the electricity generated by hydroelectric installations. However, given the long lifespan of a hydroelectric power plant (50 to 100 years), these emissions are offset by emission-free hydroelectric energy.
