Tidal Energy

3. There are numerous locations for tidal power around the world. Other websites online have this number at 40, however the coast of British Columbia, Canada has 89 alone.
5. The potentially larger footprint of TSG farms could reduce shipping and recreation areas.
7. Tidal power devices are fully or nearly completely submerged in water well offshore. This reduces the damaging of water views that has been associated with offshore wind turbines.
9. Needed to spin turbines to create energy.
10. During the early middle ages they are one of the first recorded to use tide mills.
11. Changes in tidal movement could substantially reduce efficiency of TSGs.
12. Amount of mill operating along the shores of the Atlantic
15. Tides move constantly throughout the day, which provides a consistent stream of electricity generation capacity.
16. Person that found that of the 23 remaining tidal mills in England, only 10 were still working without modern electrical power.
17. Tidal Power converts roughly 80% of the kinetic energy into electricity, as opposed to coal and oil which convert only 30% of the energy held within.
18. Archaeological information has also shown that the ____________ may have also used tide mills.
19. The part of the system that gets turned by wave energy.

1. By taking advantage of only the tide, tidal power creates no greenhouse gas emissions or water pollutants.
2. No material resources are used or changed in the production of tidal power, making it a truly renewable power form.
4. Once installed there are few ongoing operating costs or labor costs, unless there is a device breakdown.
6. There are relatively few commercial installations as compared to other technologies, such as wind and solar farms. As such, additional difficulties implementing these TSG devices could arise.
7. Sea life could be harmed by the blades in the open and Venturi turbines. The floor mounting of TSGs could also disrupt the habitats of different sea life and plants.
8. By the _____________ Century the use of tide mills had declined dramatically.
13. The high cost of the different TSGs and cost of installing power lines underwater could lengthen the payback period and be cost prohibitive based on the characteristics and size of each project.
14. Strong ocean storms and salt water corrosion can damage the devices, which could increase the cost of construction to increase durability and/or cause frequent breakdowns.
