Both hydropower and tidal power are generated by water flow that is constantly renewed.
(However, generating tidal power will have a negligibly tiny effect on the orbit of the Moon.)
Water is a renewable resource, since it is renewed by rain.
Water has a cycle, which makes it renewable.
hydrotropotrism
Actual.
A renewable resource has the ability to reproduce using natural or biological processes. The answer to you question depends on how you are heating water if you are using solar energy to heat water than is a renewable resource but if you are using fossil fuel are energy that is produced by using fossil fuels( i.e electricity) then it is a non renewable resource.
The sun is a renewable source of energy. Water is not a renewable source of energy. It is a renewable resource as long as the rain keeps on falling on the same place.
Water is not a renewable resource
Hydro-Electric Power is the most renewable Energy resource that we have; while Water Still Flows.
It depends where it comes from. Energy from solar, wind, water etc is renewable. Energy from burning fossil fuel is non-renewable.
Geothermal is considered a renewable resource as it uses water and the earth's heat. Both of these are inexhaustible. However, if the water near the plant is exhausted (no more water in that area, but there is no less water than before), then the plant must be moved. It is still generally considered a renewable source of energy.
water
A non-renewable resource is one that is used up, that cannot be reused. A renewable resource is regularly replenished or can be reused. Hydro power (renewable) comes from water circulated in the water cycle, and so is continuously replenished by natural processes.
Geothermal energy is renewable because it is using heat for the earths "core" and water (turned to steam by the heat) to power steam turbines. Both the heat and water are renewable resources thus geothermal energy is renewable.
