technically yes as the gas given off buy most faeces human and animal is methane. Methane can be burned to create heat.
The word "sustainable" is used in environmental and energy circles to refer to sources of power that will not run out. With that definition, solar power is considered sustainable because we presume the sun will always shine. Wind and water are other sources of sustainable power.
Shooting feces from your fingers
Solar energy is a sustainable power source.
They eat everything in the soil then they leave their feces behind and somehow that makes soil heathy and fertile.
Yes.
No
"Sustainable" in this context refers to the source of the energy. If the thermal power plant burns petroleum for example, it is not sustainable, since there is a fairly limited supply of petroleum.
i dont know sorry.
As long as you have rain, yes.
i dont know sorry.
The renewables are Tidal energy, Wind power, Solar power and Hydro electric power
As long as the rain keeps falling, keeping the dams full, then hydro-power is 100% sustainable.
