they both rely on water
Hydroelectricity and tidal energy are similar because they are both sources of energy rely on water.

Electicity from coal, oil, natural gas, nuclear, biomass, wind, solar, tidal sources.
Water can be converted into various forms of energy, including hydropower, thermal energy from heating water, and potential energy through elevation changes in hydroelectricity. It can also be used to generate kinetic energy in the form of wave or tidal power.
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.
The original source of energy for hydroelectricity is the gravitational potential energy of water stored in dams or reservoirs. When this water is released and flows through turbines, it generates mechanical energy, which is then converted into electrical energy.
tidal energy is created by turbines that does make tidal power
Geothermal is taken from heat being made by the insides of the earth, usually in the form of hot springs and steam. Think Yellowstone. Tidal is taken from the changing of high tide to low tide and vise versa. It's a formal of hydroelectricity. Both of these are very "green" ways of harvesting energy unlike coal burning.
The process of harnessing energy from the ocean's tide is very similar to that of harnessing water through a hydroelectric dam. As the turbines turn they create energy. This happens both as the tide comes in and as the tide goes out. The turbines' energy is then routed to storage generators and sent out through power lines to feed the power needs of the community.
Tidal Barrage - uses the potential energy from high tide to low tide. Tidal Electric Resevoir - similar thing but literally a big bath tub in the sea, water in, control the output at low tide. Marine current turbines - turbines undersea Tidal Fence 'Stingray' tidal generator
