they both rely on water
Hydroelectricity and tidal energy are similar because they are both sources of energy rely on water.
hydroelectricity solar energy tidal power oil power wind power coal power nuclear power
Electicity from coal, oil, natural gas, nuclear, biomass, wind, solar, tidal sources.
The original source of energy for hydroelectricity is water.
If by alternative you mean "not fossil fuels" then the following:The kinetic energy of water (Hydroelectricity)The kinetic energy of wind (wind turbines)The rotational/tidal energy of the Earth/MoonDirect Sunlight (both heat and Photovoltaic).Geothermal energy.
The city depended on Hydroelectricity as their main energy source.
The original source of energy for hydroelectricity is water.
What energy comes from things besides fossil fuels
hydroelectricity
tidal energy is created by turbines that does make tidal power
tidal energy is be placed in the sea
Hydroelectricity
