Wind Power - Vastly Superior to Nuclear Power In Resource Use: Metal X19.2 Concrete X9.6

This goes a long way to explaining why the cost of Wind Power Farms, per MWh delivered, is so much greater than a Nuclear Power Plant !

Hinkley Point C Nuclear Power Plant is rated at 3.2 GW, has a 90% Capacity Factor and a Design Life of 60 years.
It will deliver 1,513.7 TWh of 24/7 electricity.

UK Wind Turbine Operate at a Capacity Factor of 30.4%

"...The design life of a good quality modern wind turbine is 20 years. Depending on how windy and turbulent the site is, the turbine could last for 25 years or even longer, though as with anything mechanical, the maintenance costs will increase as it gets older...."

At a Capacity Factor of 30.4% and an 'Operational Phase' of 25 years, to deliver 1,513.7 TWh of intermittent electricity, the UK would need a Wind Turbine Total Operational Capacity of 22,736.422 MW.

Metals Use, Hinkley Point C: 141,806 tonne.
Metals Use UK Wind Power: 2,723,823 tonne [X19.2].

Concrete Use, Hinkley Point C: 1,022,490 tonne.
Concrete Use UK Wind Power: 9,844,871 tonne [X9.6].

A lot of people have fought oppression for the right to have wind turbines, but John Cleese gets right to the heart of the matter at 1:34 on this:

Rampion Ramps Up The Cost Of Offshore Wind.

Everything you need to know about Rampion here:

Rampion Offshore Wind Farm is rated at 400.2 MW and will cost £1.596 billion.

That's a costs of £3.99 Billion/GW installed.

Rampion will deliver Intermittent Electricity, capable of Intermittently Powering 283,444 homes [which works through to a Capacity Factor of 31.8%]. Its 'Expected Life' is 25 years.

By contrast, Hinkley Point C Nuclear Power Plant will deliver 24/7 Electricity, capable of On-Demand Powering of 6,406,501 homes [its capacity factor is 90%].
Its 'Design Life is 60 years.

A bit of very simple Arithmetic:

(Hinkley Homes Powered x Design Life)
divided by
(Rampion Homes Powered x Expected Life)
= 54

We'd need to build 54 Rampions to deliver the same amount of electricity as Hinkley !

That would cost 54 x £1.596 billion = £86.18 billion

 For this money, nearly 5 Hinkley Point C nuclear power plants could be built, supplying almost 5X more Low-Carbon electricity - 24/7, On-Demand.

The area Rampion occupies is 79 sq. km. 
54 Rampions would occupy an area equivalent to 
65 km x 65 km

Coincidentally, that's just about the area occupied by the complete map [above] showing the location of Rampion.

Hinkley sits on a site 870 m x 870 m
