It, depends on if you mean is it expensive to start up or to run, because once you have started the tidal energy up, it is free to run (costs no money to run)
A 1,000MW wave and tidal power system could create up to 2,000 manufacturing an installation jobs. It could also create 100 permanent jobs.
Tidal power harnesses the power of the water as the tides ebb and flow through a narrow outlet to the sea.Wave power harnesses the constant to and fro, or up and down, of the ocean waves.
The main disadvantage with an oil station over a tidal one is that the oil station produces much higher levels of pollution - specifically CO2. Added to this is the fact that all fossil fuel power station are running on finite resources - there is a lot of debate about how much fossils fuels we actually have left but everyone agrees that at SOME POINT it will run out.In addition to the environmental reasons, an oil plant would likely cost a lot more to build, it is mush more visible and an eyesore to most people.On the plus side for oil plants:The technology is well understood, tidal is getting there but is not a fully fledged method of power generation yet.An oil plant would create lots of jobsFossil fuel plants are very reliable (tidal is as well)And most importantly - if you want more power you can turn it up. This isn't really an option with tidal plants.
Yes. Tidal energy is renewable The energy of the tides will not go away if we use their power to generate electricity. It is renewable in the sense that we cannot take away the source of the energy by using them (unlike fossil fuels, of which there is a limited supply. No matter what use we may make of the tides, we do not use them up. The tides will continue to ebb and flow, driven by gravitational forces.

Tidal power needs a suitable bay or river mouth that fills up with massive amounts of water at high tide, but that only has a small exit to the sea, otherwise it is not economical. There are not many suitable locations in the US for tidal power.
Item (set-up) costs, holding (storage) costs, and shortage costs (demand > product).

Costs are variable to run a wind turbine , the major cost is in the set up , after that it's just maintenance. The variables are size, power output, setup costs, etc...
Because it reduces the fuel costs; you don't have to pay for shipping the fuel.

A good place for a tidal barrage is somewhere like a river mouth, or a bay that has a narrow opening to the sea. You want a lot of water to come into the collection area at high tide, and then you want to catch it all in as small an area as possible to set up your turbines to harness the power of all the water. The Rance River Power Station in Brittany, France, is the world's first tidal power station. See link below.
*High set up costs - Moulds etc *Complicated process *can only be used for large quantities due to costs
A national park costs about $800,000 - $1,000,000
If you can get to pewter then go east from the mart and as you go east you will see a set of lines which look like stairs go up them and you will see an old man talk to him and if you have all 16 badges i think he will give you the tidal bell
