Tidal Energy: Harnessing Environmental Technology for Renewable Energy
Tidal energy, also known as tidal power, is a form of renewable energy that harnesses the natural ebb and flow of ocean tides to generate electricity. It holds great potential as an alternative source of energy due to its reliability and predictability. To better understand the concept of tidal energy, let us consider a hypothetical case study.
Wind Energy Basics | Department of Energy
Wind energy is actually a byproduct of the sun. The sun's uneven heating of the atmosphere, the earth's irregular surfaces (mountains and valleys), and the planet's revolution around the sun all combine to create wind. Since wind is in plentiful supply, it's a sustainable resource for as long as the sun's rays heat the planet.
How electricity is generated
Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.
Tidal power: a promising and sustainable renewable energy source
Tidal power offers several advantages as a renewable energy source: Predictability: unlike the sun and wind, tides are regular and predictable, enabling more precise planning of electricity production. Energy density: since water is around 800 times denser than air, ocean currents can carry more energy than wind, even at lower speeds.

Your idea about tidal friction draining energy from other forms is completely correct, however. So let's start with the effects of the moon tides. The facts are that the moon is moving away from the earth at about 3.8 cm per year and that the earth's days are getting longer at about 2 milliseconds per century.

Tidal Energy | The Canadian Encyclopedia
The country's potential tidal energy production is more than 42 million kW. The idea of exploiting the energy of the tides is not new. Tidal mills were built in Britain, France and Spain as early as the twelfth century. A mill powered partially by tidal energy was built at Port-Royal, Nova Scotia in 1607. These early mills extracted the ...
Tidal energy-path towards sustainable energy: A technical …
In the tidal energy system, different features work in a combined way to measure the desired output. A tidal power plant's control method includes the idea of hydrokinetic energy.
