Hydroelectric dams, tidal energy, and wind energy systems all harness renewable energy sources to generate electricity, contributing to a reduction in greenhouse gas emissions. They rely on natural processes—water flow in the case of hydro and tidal energy, and air movement for wind energy—making them sustainable alternatives to fossil fuels. Additionally, all three technologies can have environmental impacts and require careful site selection to balance energy production with ecological preservation.
Hydroelectric plants use energy from moving water
Tidal Energy
As sustain means to keep going sustainable energy comes from wind,and tidal power for example
Tidal power contributes to a small fraction of the world's energy production, accounting for about 0.1% of the total energy supply. While it is a renewable resource with significant potential, its current contributions remain limited compared to other renewable sources like solar and wind. The development of tidal energy is still in its early stages, with ongoing research and projects aimed at increasing its viability and efficiency.
Fossil fuels are running out quickly, as evidenced by the recent rise in the cost of gasoline due to the negative speculation regarding the "Libya crisis". Whereas 'wave' or 'tidal' energy is naturally occurring and 'renewable'.

Hydroelectric/Tidal, Solar, Wind, Geothermal, Bioenergy/Biomass energy are all renewable.
Tidal energy can be used to generate electricity through tidal stream systems, which harness the kinetic energy of moving water, or through tidal barrage systems, which use the potential energy of changing water levels to turn turbines and generate power.
Water is used in hydroelectric energy production. The mechanical energy of moving water is transferred by a rotating turbine to a generator, where it is converted to electric energy and conveyed along transmission lines.
Hydroelectric power
Yes, the tide can be used to generate electricity through tidal energy systems. These systems harness the kinetic energy of the moving water to turn turbines and generate electricity, similar to how hydroelectric systems generate power from flowing water.
