Introduction
Tidal power is a machine that gets energy from tides, which then is used to power electricity. Tidal power comes from gravitational forces from the sun and moon. Tidal energy is made though the use of tidal energy generators. Turbines are placed in high tidal movement, and designed to capture the kinetic motion in order to produce electricity.
Pros and Cons
Tidal power energy is renewable. Tidal power is kind and doesn't harm the environment.Tidal currents are easy to predicate. some bad things about Tidal Power is that it is so expensive ,also tidal power plants are way to close to land . Finally science the power [plants are to close to land it harms the environment in many different ways.
Environmental impact
Tidal Power is a distraction of habitats, interruption of in organisms. Also there is a potential electromagnetic interference, also potentate acoustic pollution. also t\his machine kills fish, and other organisms in this area.
Costs
The cost of building power plants ranges from 3 billion to 15 billion. Some places spend 10 million dollars to power 25 houses. I realized from my research that people sped so much of money to have these machines. Tidal power can produce 4,2 to 6,5 cents per kilowatt-hour at three locations.
Current News
The world's biggest tidal energy generator is located in Scotland . The blades are 18 meters long, and 59 feet across! It weighs 143 tons or 286,000 pounds. It stands at 22.5 meters tall or 70 feet height! It is able to power over 1,000 homes!
Fun Facts
Did you know that tidal energy is absorbs the sun and moons gravitational forces! Also tidal power is produces electricity though water! The author ion interesting facts stated that "The tide moves a huge amount of water twice each day, and although the tidal energy supply is reliable and plentiful, converting it into useful electricity power is not easy." This makes me think that we have a very powerful electricity to do these amazing things.
