No, you can not reduce 'the grid' storage etc. does not help you in any way having the necessary capacity to transport the amount of energy that is needed at a certain time.

It only helps you to store surplus and leaves you the option not to power up plants but use the previously stored surplus.

Bottom lime for a random factory close to you, the grid changes not at all.

Hint: if your town needs 2GW power around noon, the grid has to handle 2GW, it does not care if the power comes from a plant or a battery close to you. The total energy is the same.

Why don't youndo the math then?
Energy is m * v ^ 2.

Obviously doubeling the v goes to the square for total energy, while doubeling the mass only doubles the energy.

Wind energy increases in a turbine with the speed by the cube because first of all the air follows the same e = m * v ^ 2 ... but on top of that if you double the speed not only do you have (2 * v) ^ 2 but also (2 * m) as in the same time, now twice the mass of air goes through the turbine (twice the mass times twice the speed).

You do know that Scottland and also other european countries have test installations in sea water since over 20 years?

Ah, you don't ... how smart to point out the obvious. I really wonder why eceryone on /. always think that some random european engineers and companies (especially if it is regarding energy) are idiots?

ocean swells which could've provided energy to propel ships.
Energy yes.
but you are aware that wind and sails are a very simple means to propell a ship without any need to store/convert energy and then use it in a special device likema propeller?

It's because average wind energy is denser than the fraction of wave energy you can extract from something bobbing on the surface.

That is nonsense.

The rest of your post makes not much sense either. Who cares about efficiency? The only things that are relevant are: cost, space, amount of energy/power produced. Who cares if the wave only gives away 10% of their total energy due to that? What has that to do with any rational meams of the term 'efficiency'?

Wrong on all accounts.

Neither is the energy of waves to low nor do they rip anything apart. And yes, around coasts waves are very common ... no idea why you think waves would not be available at some spots ... sure, big lakes, even the meditarien, might be to small. But oceans always have waves.

We are talking here about off shore waves, not breakers that ram into a steep coast.

Wave energy systems we have since decades. But so far they where not economic (durability, maintenance etc. ) feasable.

Ofc smart grids help.
Especially if they have access to grid wide 'storage' ...
Nevertheless ... actually you mix up but half correctly use 'peak power' ... we are storing in this situations only very low percentages of the daily produced energy. And also only very low percentages of the power consumption.
SmartGrids like I believe you mean them, are usefull to prevent wasting the peak solar energy around day time ... they don't help at all to cut down on the grid to be scaled for peak, as the peak is still there.

So your comment smells of trolling with no real insight in the field.
Two mistakes in one sentence, hohohoho. Go figure ...

Yeah yeah ... americans with their braindead idea how power grids work. As if it was not possible â" even in the USA â" to read up about it.
For starters: "peak demand" is not at the morning when everyone stays up, but it starts around 10:00/11:00 and lasts till 15:00/16:00.
Of course power grids need to be build for the peak and not for the average ... how else would you meat peak demand?
No idea about your project, sounds like a household project to me ... as soon as even the simplest garage, bakery or small shop is 'connected' you simply can forget battery storage.

If there is dead squirrel in a transformator, it certainly died not on shortening some power ...
Must be very difficult anyhow to make transformators sqirrel proof.
Who showed them how to get inside? What tools do they use?
Or are they simply smarter than the european ones?

In every non-trivial program there is at least one bug.

Working...
