Offshore Wind Power Cheaper Than New Nuclear

Status

Great news!  I see the Rampion Field offshore from Brighton is progressing – from Brighton Clock Tower looking down West Street, a rig and towers visible on horizon and full extent surprised me recently as it came into view whilst driving along A259 from Eastbourne.

Offshore wind power cheaper than new nuclear.  [ABRIDGED]

Energy from offshore wind in the UK will be cheaper than electricity from new nuclear power for the first time.  The development, revealed in figures from the government, has been seen as a milestone in the advance of renewable energy.

The plummeting cost of offshore wind energy has caught even its most optimistic supporters by surprise.  Nuclear firms said the UK still needed a mix of low-carbon energy, especially for when wind power was not possible.  The figures, from the Department for Business, Energy and Industrial Strategy, for offshore wind were revealed as the result of an auction for subsidies, in which the lowest bidder wins.

Two firms said they were willing to build offshore wind farms for a subsidy of £57.50 per megawatt hour. That compares with new nuclear plants at a subsidy of £92.50 per megawatt hour for 2022-23.

Emma Pinchbeck from the wind energy trade body Renewable UK told the BBC: “These figures are truly astonishing.  “We still think nuclear can be part of the mix – but our industry has shown how to drive costs down, and now they need to do the same.”

‘Energy revolution.’

Onshore wind power and solar energy are already both cost-competitive with gas in some places in the UK.  And the price of energy from offshore wind has now halved in less than five years.

Energy analysts said UK government policy helped to lower the costs by nurturing the fledgling industry, then incentivising it to expand – and then demanding firms should bid in auction for their subsidies.

Michael Grubb, professor of energy policy at University College London, called the cost reduction “a huge step forward in the energy revolution”.  “It shows that Britain’s biggest renewable resource – and least politically problematic – is available at reasonable cost.  It’ll be like the North Sea oil and gas industry: it started off expensive, then as the industry expanded, costs fell. We can expect offshore wind costs to fall more, too,” he said.

The subsidies, paid from a levy on consumer bills, will run for 15 years – unlike nuclear subsidies which run for 35 years.  This adds to the cost advantage offshore wind has now established over new nuclear.  Caroline Lucas, co-leader of the Green Party, said: “This massive price drop for offshore wind is a huge boost for the renewables industry and should be the nail in the coffin for new nuclear.  “The government’s undying commitment to new nuclear risks locking us into sky high prices for years to come. Put simply, this news should be the death knell for Hinkley C nuclear station.”

Nuclear ‘still needed.’

However, the nuclear industry said that because wind power is intermittent, nuclear energy would still be needed.  Tom Greatrex, chief executive of the Nuclear Industry Association, said: “It doesn’t matter how low the price of offshore wind is. On last year’s figures it only produced electricity for 36% of the time.”

EDF, which is building the Hinkley Point C nuclear plant, said the UK still needed a “diverse, well-balanced” mix of low-carbon energy.  “New nuclear remains competitive for consumers who face extra costs in providing back-up power when the wind doesn’t blow or the sun doesn’t shine,” the French firm said.  “There are also costs of dealing with excess electricity when there is too much wind or sun.”

Construction of the Hinkley Point plant is under way after gaining government approval last year.  EDF added that energy from new nuclear plants would become cheaper as the market matures, as has happened with offshore wind.  Eyes will be raised at this suggestion, as nuclear power has already received subsidies since the 1950s but storage of surplus energy from offshore wind is still a challenge.

Prof Grubb estimated the new offshore wind farms would supply about 2% of UK electricity demand, with a net cost to consumers of under £5 per year.

Experts warn that in order to meet the UK’s long term climate goals, additional sources of low-carbon energy will still be needed.

August Sightings.

Thursday, Aug 3.  Rather un-seasonal weather during the past 24 hours with substantial rainfall through yesterday afternoon and through much of the night.  That has been followed today with quite windy conditions – Force 7- Near Gale, being recorded out in the Channel and the average wave height reaching 6.5 feet, producing plenty of white-crested waves.

Sunday, Aug 13.  Slow boat to Turkey – a new twist on that old saying!  A dutch tug, the Fairmount Glacier, 3,239 gross tonnes, is on passage towing a large drilling rig to Aliaga in Turkey.  It is shadowed by the Belgium-registered offshore support vessel, Smit Nicobar of 2,606 gross tonnes.  The towering rig was a feature on the horizon for much of the day off Hastings for it is travelling only between 2 – 6 knots, walking pace!  Monday morning and they were south of the Isle of Wight.  ETA in Turkey is September 10th!

Friday, Aug 18.  There has been much talk just recently about the amount of rain this month.  One of the BBC weathermen was asked for an explanation about it.  He stated that of ‘the last 13 consecutive Augusts, 9 had been wetter than the average, perhaps indicating a new trend.’

Wed, Aug 30.  Quite a number of house martins hawking above the town this evening, probably because of their migration being put on hold by the wet, cloudy weather and less than perfect visibility?

June Sightings

June 5th.  At breakfast time, noticed a very large ship going down Channel.  It proved to be the MSC Zoe (which with several sister ships) is one of the largest container ships in the world (as of August 2015), it being the third of a series of ships built by the Mediterranean Shipping Company.  She takes her name from the four year old granddaughter of Gianluigi Aponte, the Mediterranean Shipping Company president and chief executive.

MSC Zoe was constructed by Daewoo in South Korea for $140m.  The ship’s particulars are: at a length of 395 metres and has a draft of 16 metres.  She has a capacity of 19,224 TEU (containers) and a deadweight of 199,272 DWT.  The vessel’s massive main engine is a two-stroke MAN B&W 11S90ME-C diesel engine, which has a height of 15.5 m (51 ft), a length of 25 m (82 ft) and a breadth of 11 m (36 ft).  The engine has a maximum continuous rating of 62.5 MW (83,800 hp) at 82.2 rpm and a normal continuous rating of 56.25 MW (75,430 hp) at 79.4 rpm.  Her single five-blade propeller has blade lengths of 10.5 m (34 ft) producing a service speed of 22.8 kn (42.2 km/h; 26.2 mph)

June 6.  In view of last night’s un-seasonal gale, I have added a Page* setting-out the Beaufort Scale, the universally accepted scale for wind speed.  In mid-Channel at about 8-9am this morning, it reached Severe Gale force.  Nowadays – even in tv/radio weather forecasts, the term ‘gale’ or ‘storm’ are often misused, so here’s the correct calibration!  *Scroll back to the top of the ‘Reflections’ blog screen and click on Beaufort Wind Scale.  The sea has been wild all day with 2-3 metre waves breaking on the beaches; even by the evening, the wind speed was still registering in the region of Force 7 – ‘Near Gale,’ very un-seasonal for June!

June 11.  There was very good visibility tonight out into the Channel where the cruise liner Arcadia, was slowly passing west along the Sussex coast on passage to Southampton, when I noticed a cluster of lights and orange glow on the very far horizon.  On doing a simple exercise or two on Google Earth, it would seem to be Boulogne, some 45 miles to the south-east!

Today, a 350 tonne transformer was transported by road from Shoreham to Ninfield, see link  https://sussex.police.uk/news/drone-footage-captures-abnormal-load-journey-through-east-sussex/

June 13.  After an apparent absence of about a week due to the un-seasonal windy weather, swifts have returned this morning to hawk insects high above St.Leonards old town. These enigmatic birds have been one of my favourite birds since early childhood.

Late afternoon on the 13th and one Hastings Arrows that’s never going to find its destination!  The engine compartment and almost the whole of interior of the bus being gutted.

June 18.  My strawberries now in full production on the wonderful Marina Allotments!  I came across this thought prvoking quote while on Twitter: “For every kilogram of vegetables you grow yourself, you’re reducing greenhouse gas emissions by 2 kilograms…”

Noticed this colony of relatively large digger wasps under the attractive stone flagstones in Pevensey Road.

June 19.  Heatwave.  These  fella’s have the right idea while working in the heat!

While picking another dish-full of strawberries this evening, I heard an approaching bird call and immediately thought I know what’s making that call.  On looking up, a pale-looking ring-necked parakeet flew over, did a circuit nearby and then disappeared towards neighbouring housing.  A summer escape or from a feral colony nearby?

Trump Pulls Out of Climate Deal

Trump yesterday has confirmed what most sensible people feared.  This man is arrogant, selfish and shows himself to be ignorant and stupid!  He is putting mankind and this beautiful planet in serious jeopardy.

http://www.bbc.co.uk/news/world-us-canada-40128266#

June 1 2017.  [Abridged]

Trump climate deal pullout: The global reaction.  President Donald Trump’s announcement that the US is withdrawing from the 2015 Paris climate agreement has drawn strong reaction from supporters and opponents inside America and from around the world…

Former President Barack Obama, who negotiated the deal for Paris the US:

“The nations that remain in the Paris Agreement will be the nations that reap the benefits in jobs and industries created. I believe the United States of America should be at the front of the pack. But even in the absence of American leadership; even as this Administration joins a small handful of nations that reject the future; that our states, cities, and businesses will step up and do even more to lead the way, and help protect I’m confident for future generations the one planet we’ve got.”

French President Emmanuel Macron:

“I tell you firmly tonight: We will not renegotiate a less ambitious accord. There is no way. Don’t be mistaken on climate; there is no plan B because there is no planet B.”

Elon Musk, entrepreneur and Tesla Inc CEO who had served on a White House advisory council:

“Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world,”

US Senator Bernie Sanders, former Democratic presidential candidate:

“At this moment, when climate change is already causing devastating harm around the world, we do not have the moral right to turn our backs on efforts to preserve this planet for future generations.”

Democratic Mayor of New York, Bill de Blasio:

“President Trump can turn his back on the world, but the world cannot ignore the very real threat of climate change. This decision is an immoral assault on the public health, safety and security of everyone on this planet. On behalf of the people of New York City, and alongside mayors across the country, I am committing to honour the goals of the Paris agreement with an executive order in the coming days, so our city can remain a home for generations to come.”

Democratic former US Secretary of State John Kerry:

“The president who promised “America First” has taken a self-destructive step that puts our nation last. This is an unprecedented forfeiture of American leadership which will cost us influence, cost us jobs, and invite other countries to walk away from solving humanity’s most existential crisis. It isolates the United States after we had united the world.”

Republican US House Speaker Paul Ryan:

“The Paris climate agreement was simply a raw deal for America. Signed by President Obama without Senate ratification, it would have driven up the cost of energy, hitting middle-class and low-income Americans the hardest. I commend President Trump for fulfilling his commitment to the American people and withdrawing from this bad deal.”

US Senate Democratic leader Chuck Schumer:

“President Trump’s decision to withdraw from the Paris Climate Agreement is a devastating failure of historic proportions. Future generations will look back on President Trump’s decision as one of the worst policy moves made in the 21st century because of the huge damage to our economy, our environment and our geopolitical standing.”

Peabody Energy, largest coal mining firm in the US:

“Peabody supports the administration’s decision to withdraw from the Paris Agreement. We believe that abiding by the accord, without significant changes, would have substantially impacted the US economy, increased electricity costs and required the power sector to rely on less diverse and more intermittent energy. Peabody continues to advocate for greater use of technology to meet the world’s need for energy security, economic growth and energy solutions through high efficiency low emissions coal-fuelled power plants and research and development funding for carbon capture.”

UK Prime Minister Theresa May – a Downing Street statement:

“The Prime Minister expressed her disappointment with the decision and stressed that the UK remained committed to the Paris Agreement. The Paris Agreement provides the right global framework for protecting the prosperity and security of future generations, while keeping energy affordable and secure for our citizens and businesses.”

UN Secretary-General Antonio Guterres (via spokesman Stephane Dujarric):

“The decision by the United States to withdraw from the Paris Agreement on climate change is a major disappointment for global efforts to reduce greenhouse gas emissions and promote global security. It is crucial that the United States remains a leader on environmental issues.”

Canadian Prime Minister Justin Trudeau:

“We are deeply disappointed that the United States federal government has decided to withdraw from the Paris Agreement. Canada is unwavering in our commitment to fight climate change and support clean economic growth.”

European Commission climate action commissioner Miguel Arias Cañete:

“Today is a sad day for the global community, as a key partner turns its back on the fight against climate change. The EU deeply regrets the unilateral decision by the Trump administration to withdraw the US from the Paris Agreement.”

President Frank Bainimarama of Fiji, which is organising the next UN annual climate meeting, COP23:

“The decision by the Trump Administration to withdraw from the Paris Agreement on climate change is deeply disappointing, especially for the citizens of vulnerable nations throughout the world. As incoming President of COP23, I did what I could – along with many leaders around the world – to try to persuade President Trump to remain standing shoulder-to-shoulder with us as, together, we tackle the greatest challenge our planet has ever faced. While the loss of America’s leadership is unfortunate, this is a struggle that is far from over.”

May Sightings

And so the cool, dry spring continues without much prospect of change until towards the end of May…

May 6th and during the evening there was a group of 7 swifts hawking for insects in the cold easterly wind, high over St.Leonards old town.  Still numbers of turnstones along the beach.  May 8th and as I sat down to my breakfast, 6 swallows flew across the street at window height in that purposeful, determined flight behaviour that characterises swallows on migration, heading north-westwards.  I wished them well.

May 8th.  There’s still a reasonable population of english elms in the vicinity of the station at Pevensey.  Also nearby, are a number of trees (poplar?) with thriving plants of mistletoe high in their crowns; nice to see.

May 18th.  In the following pic, scrub-bashing with a difference!  These fellas are removing dense ivy from off the cliff face at Rock-A-nor at Hastings in order to attach steel mesh safety netting as can be seen above them.  They’re working from off ropes using pneumatically powered equipment.

 

On the same day in the evening, saw this amazing ‘barley-twist’ cloud formation.

May 24th.  There were 10 swifts over St.Leonards old town as I sat having breakfast. Went for a walk in Ham Street Woods National Nature Reserve in Kent, a lovely wood but unfortunately there appears to be not a lot of coppicing now going on – how this wood was traditionally managed.  Saw this tree which many years ago had suffered severe trauma, survived and prospered!

Nearby the entrance to the woods stands a row of four Victorian(?) cottages.  I thought they were very unusual in that the upper storey is clad all around the entire block with butt-jointed slates with strips fixed over the vertical joints.

On this jaunt I travelled by train and spotted just west of Winchelsea good and bad farming practice – the latter almost certainly contravening government/EU regulations by cultivating as close to a watercourse as physically possible.  The adjacent water must be receiving a very unhealthy cocktail of fertilizer and chemicals  First, good practice with 2 metre wide uncultivated headlands on a neighbouring farm and then the bad.  Apologies that the second doesn’t make the point very obvious but the train was going quite fast! Stile and post are on nearside of watercourse.

In the evening, saw my first painted lady butterfly; it was in beautiful condition and probably had not long arrived from across the Channel.  About 10 swifts screaming high overhead mid-evening.  I’m not religious but full marks to the Pope for giving Trump some serious reading matter today!

April Sightings  – All and Sundry

Up until the early part of the month (including the winter), I’ve been surprised just how tolerant of people that the dozens of turnstones that wintered/rested on the beaches of St.Leonards and on the ironwork of Hastings pier are.

Moving on, a couple of days ago, many of the birds in the centre of the town flew-up and seemed uneasy for a few minutes; I scanned the skies and sure enough, a couple hundred yards away and high up, was a circling sparrowhawk.

Went for a lovely walk with a friend in the Iden area on Sunday, April 9th – that really warm day.  We walked through an area of working coppice with a beautiful display of bluebells and lesser celandine.  After refuelling, on the return leg we saw two swallows, one settled on a nearby telephone wire giving out that gorgeous trilling song as if to say, ‘well, I’m glad to be back.’  Walking along part of the banks of the Military Canal, we were treated to a short, announcing blast from a cetti’s warbler emanating from out of the bordering reeds.

Back at home, somewhere not far from the house, there seems to be a pair of goldfinches possibly nesting; lovely to sit on the steps by the front door and watch them frequently pass over with their singing, resembling a bunch of high-pitched jangling keys.

April 26th and on a walk near Matfield in Kent, we came across a small meadow which was stunning!  It had thousands of cuckoo flower in full bloom, a real high-point in the day.

I’m now able from my window, to take an interest in the shipping passing down the Channel – ships being a subject that I’ve been fascinated by since a child.  I’m surprised by the sheer number of container ships passing by with quite a number owned by the MSC shipping company – the second largest container fleet in the world with 490 ships, four of which are the largest in the world.

Tallest Wave Ever Recorded

https://uk.yahoo.com/news/six-storey-high-wave-sets-record-says-un-160527273.html

Six-storey-high wave sets a record, says UN agency

13 December 2016.

The UN’s weather agency on Tuesday announced the highest wave on record – a behemoth that towered 19 metres (62.3 feet) above the North Atlantic. Scrutiny of data sent back by an automated buoy showed a monster wave rose at 0600 GMT on February 4, 2013 at a remote spot between Britain and Iceland, the World Meteorological Organization (WMO) said. “This is the first time we have ever measured a wave of 19 meters. It is a remarkable record,” WMO deputy chief Wenjian Zhang said in a statement. Taller than a six-storey building, the mighty wave occurred after a “very strong” cold front had barrelled through the area, producing winds up of 43.8 knots (81 kilometres, 50.4 miles per hour). The previous record height for a wave was 18.3m, notched up in December 2007, also in the North Atlantic.

Automated buoys are vital tools for oceanographers, sending back data on sea currents, temperatures and swells for seafarers, climate researchers and others. “We need high quality and extensive ocean records to help in our understanding of weather/ocean interactions,” said Zhang. “Despite the huge strides in satellite technology, the sustained observations and data records from moored and drifting buoys and ships still play a major role in this respect.” The North Atlantic, from the Grand Banks underwater plateau off Canada to south of Iceland and the west of Britain, is the world’s biggest breeding ground for giant waves. At wintertime, wind circulation and atmospheric pressure cause intense extratropical storms, often dubbed “bombs,” the WMO said. The height of a wave is defined as the distance from the crest of one wave to the trough of the next.

The UN agency occasionally reveals quirky weather-related milestones, like its September finding that an August 2012 lightning flash in France was the longest-lasting bolt ever recorded.

Storm Angus

Storm Angus.  Well, after a night of listening to the wind in the trees and the rain lashing down, I received text at 6-30am from my colleague Sally saying as she lives not too far away, she’d go and check the electric fencing on the 3 coastal pony grazing sites near Beachy Head.  7-30, she text to say she’d sorted the battered fences at Frances Bottom.  8-30am and another text, saying that the cliff top fence at Shooters Bottom towards Belle Tout was in one hell of a mess, so I phoned and said I’d set set-off immediately to assist her.  This fence would have taken the full brunt of the storm.

When I arrived on site at 9-30, I’ve not seen electric fencing so blown about, some it in small heaps even with the odd metal stake still attached and within it!  We basically had to untangle the three lines of wire and tape, and re-erect most of the 850 metres of the cliff facing fence, we finishing at about midday.  Conditions were very windy at first and quite cold but at least it was dry.

20161120_094707

These two pics I took just before 9-30, before starting work and showing the white surf on the rocks below Belle Tout and the fencing largely laying on the ground.

We then went on to Birling Gap and fortunately Nick the looker there for today is quite practical and he’d turned the power off and had just about finished re-ercting sections by the time we arrived. Fortunately, it usually works that the ponies move away from the wind thus retreating from where the fence is being damaged and where they could get out.  Just for good measure, I then walked the 1700 metres of fencing at Ashdown Forest on the way home.

Statistics.  The shipping forecast was for the possibility of a Force 10 Storm but out at the Greenwich Light Buoy, 20 miles out from the coast off Peacehaven, the maximum wind speed briefly recorded was at 7am and at 75mph, technically into the Force 12 Hurricane zone.  (This, it has to be remembered is over open sea where wind speeds are a little higher).

Concern Over Mediterranean and Climate Change

http://science.sciencemag.org/content/354/6311/465?utm_source=sciencemagazine&utm_medium=twitter&utm_campaign=6311issue-8699

A warming limit for the Mediterranean basin.

Pollen cores from sediments provide rich detail on the history of vegetation and climate in the Mediterranean during the Holocene (the most recent ~10,000 years). Guiot and Cramer used this information as a baseline against which to compare predictions of future climate and vegetation under different climate-change scenarios. Vegetation and land-use systems observed in the Holocene records may persist under a 1.5°C warming above preindustrial temperature levels. A 2°C warming, however, is likely over the next century to produce ecosystems in the Mediterranean basin that have no analog in the past 10,000 years.

Abstract.

The United Nations Framework Convention on Climate Change Paris Agreement of December 2015 aims to maintain the global average warming well below 2°C above the preindustrial level. In the Mediterranean basin, recent pollen-based reconstructions of climate and ecosystem variability over the past 10,000 years provide insights regarding the implications of warming thresholds for biodiversity and land-use potential. We compare scenarios of climate-driven future change in land ecosystems with reconstructed ecosystem dynamics during the past 10,000 years. Only a 1.5°C warming scenario permits ecosystems to remain within the Holocene variability. At or above 2°C of warming, climatic change will generate Mediterranean land ecosystem changes that are unmatched in the Holocene, a period characterized by recurring precipitation deficits rather than temperature anomalies.
