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

14.67% Capacity Factor For Wind Power In China In 2015 !!!!!





BUT THEY LET IT SLIP IN THIS REPORT !


ASIA: REMARKABLE YEAR FOR CHINA For the seventh year in a row, Asia was the world’s largest regional market for new wind power development, with capacity additions totalling nearly 33.9 GW. 

In terms of annual installations China maintained its leadership position. China added 30.8 GW of new capacity in 2015, once again the highest annual number for any country ever. This is almost twice the 2013 figure, when China installed 16 GW of new capacity. 


In 2015, wind power generation reached 186.3 TWh, accounting for 3.3% of total electricity generation . This follows a pattern of steady increase in wind based electricity generation despite heavy curtailment. In 2012, wind-generated electricity in China was just over a 100 TWh, accounting for 2% of the country's total electricity output. Wind provided almost 135 TWh of electricity in 2013, contributing 2.6% of the country's total electricity generation . Total wind power generation reached over 153 TWh in 2014, 2.78% of total electricity generation. 

The Chinese wind market almost doubled its capacity from 75 GW in 2012 to reach[ed] 145 GW by the end of 2015, reinforcing China’s lead in terms of cumulative installed wind power capacity.
And Here's How It Works Out:

Yeeaa !! A Global Grid to Transport Clean Energy Around The World !!

Offshore Wind - Guess What ! - THE BIGGER THE TURBINES, THE MORE IT ALL COSTS !!!

Hot off the press:  23/05/2016 9:38 am

Beatrice Offshore Wind Farm is rated at 588 MW and will cost £2.6 billion.

That's a costs £4.42 Billion/GW installed.

Beatrice will supply 450,000 homes which works through to a Capacity Factor of 35.9%

It's 'Operational Phase' is 25 years. So over its working life it will deliver 46.2 TW hours of intermittent, low-carbon electricity.

By contrast, Hinkley Point C Nuclear Power Plant will deliver 1513.7 TWh of 24/7, on demand, low-carbon electricity.

33 offshore wind farms, the size of Beatrice, would have to be constructed to deliver the same units of electricity as Hinkley.

33 x £2.6 billion = £85.8 billion.

Hinkley will cost £18 billion, so:

 For this money, nuclear power would supply about 4.77X more low-carbon electricity (24/7, on demand). 

From that website slide, the area of Beatrice 'eyeballs' at about 18 km x 8 km = 144 sq km

33 such windfarms would occupy an area of 4752 sq km, which is near enough 70 km x 70 km.
That's about the area of the sea's surface shown on the inset map.

Hinkley sits on a site 0.69 sq km in size.
