Book Review: The Future of Energy: Timely, but Wrong

Richard Black’s new book, The Future of Energy, is impeccably researched, well-timed. and entertainingly written for such a dense subject.

It is also focused on the wrong future.

Black is a highly respected, former BBC environmental science journalist – he left the Corporation over a decade ago because his face didn’t fit in the febrile world of accusation and counter- accusation from climate deniers, and determined greenwashing from the large corporations which had begun muscling in on the funding for environmental tech.

Black’s general approach is in line with the UK government thinking. Their planned Great British energy invesmtnet vehcile will soon be dispensing its modest budget (£8.5 billion) to assist clean energy startups of all sorts – but mainly big ones. Black thinks Coal Oil and Gas are Bad. Clean Energy is Good. Which is perfectly true as far as it goes. But despite his talk about the Rockefeller oil dynasty and the distrust of government that comes through in every chapter – Black still opts for the easy life – adopting the general consensus in the climate industry that the present system will be much like the past but cleaner and better – that we can keep living largely the same way and dong much the same things, but somehow clean energy delivered by large companies will solve our climate problems for us.

This is not the conclusion I wanted to hear, and its all the more strange because a short chunk of the book does pay lip service to off-grid energy. Pages 43-46 of the 200 page book has Black telling us:
“For me, one of the biggest attractions of the clean energy system is the power it confers on people and businesses to make their own decisions. By opting in, people can choose to rid themselves of the daily dependence on coal for the fire, petrol for the car and gas for the boiler…”
He goes on

“With P2P trading, electricity is used close to where it is generated, reducing the need for big transmission cables, substations and other grid paraphernalia.“
The centralised grid, which like most commentators Black wants to see cleaned up “decarbonised strengthened and extended – is more part of the problem than it is part of the solution.

Black’s argument is very much in the mainstream of current thought – he is going with the flow But he would do well to remember that when he argues against Oil, Gas and Coal – he is doing the nuclear industry’s job for them – jsut imageine all those energy industry bosses salivating tat the thought of the extra bonuses they will get when oil is finally stopped. True, Black criticises Just Stop Oil for their performance politics – but he makes the same mistake as JSO – not realising that the culprit is not Big Oil = it is Big Energy that got …

Memo To Rayner & Milliband – You Should Talk About Energy for Housing

The UK Government last week laid out the domestic plan for its first year in office -prioritise housing and clean energy, in order to kickstart growth.

The duo in charge of these policies – Angela Rayner (housing) and Ed Milliband (energy), did not co-ordinate their announcements last week, and there is a feeling in energy circles that both policies may fall flat for the same reason – delays in generating clean energy to the places where housing is most needed.

Housing and energy are closely connected – you cannot build new communities until the power supply is in place. We know that there is currently a 10 year wait to connect new housing estates to the grid in some parts of the country, and a 10 year wait to connect a solar farm to the grid in others.

The government also launched its vehicle for its energy initiatives last week, Great British Energy, to be run by former Siemens executive Juergen Meier. it is going into the business of picking winners – but energy for housing does not appear to be in the list. £8.5b has been announced for it to co-invest with big industry players in the next generation of wind and solar farms. But these projects take years to start generating power. It took the best part of a decade to build the Hornsea 1 Windfarm, and that was AFTER planning permission was granted in 2014. So reforms to planning permission on which the government is currently consulting are unlikely to make much impact.
And the recent history of government energy deals shows the Civil servants charged with negotiations were ham-fisted and outmanoeuvred at every turn. The UK chair of French energy company EDF, Alex Chisholm, previously ran BEIS, the department that struck the deal for EDF to build a new nuclear power station in Somerset., as reported in the Guardian. “The agreement was made in 2016 with UK bill payers bearing the costs, which soared from an estimated £18bn to at least £31bn…. it is due to be completed in 2031 – about 14 years after EDF said it would be up and running.” In 2023, EDF was the leading company in the wholesale electricity generation market in Great Britain, with a share of 18.5 percent. The UK branch of the German company RWE ranked second last year, with a market share of approximately 17.5 percent
Data centres and EVs will gobble up all the new energy the grid can produce in this country for the next ten years.
Where does that leave the new housing starts that are so badly needed? How will they get their energy this year?
The big energy consumers will always need the grid, but for at least some new housing estates, electricity could be supplied from small local microgrids that do not need to be hooked up to the main grid …

Solar Park in Wiltshire Driving Locals Green

Over 14,000 people have signed a petition against large solar farms in their area following plans for a development covering 2,000 acres (810 hectares) in Wiltshire.

Lime Down Solar Park is designed to create 500MW of clean energy – said to be enough to power 115,000 homes – from six sites in villages in the county.

Developer Island Green Power says it will give a “net gain in biodiversity”. But locals say it will simply take away land that could be used for food growing, and provide no direct benefit to the local community.

The sites would be connected into the National Grid’s substation in Melksham, the proposals say.

The finance behind Lime Down is being provided by Macquarie Bank, an Australian company dubbed the Vampire Kangaroo — an Antipodean adaptation of the ‘vampire squid’ label applied to Goldman Sachs for the way it sucked up money — so most of the income may end up overseas.

The company has been widely accused of piling up debt at Thames Water, which it owned from 2006 to 2017, contributing to the problems at the water company.

With so many question marks over the environmental credentials of solar parks, it should be a cause for deep concern that Macquarie is involved .

The local MP, James Gray, who is against the scheme, blames ‘Wall Street hooligans’ for inflicting the Lime Down plan on his constituency and believes a British company would deal with the local community more sensitively.

He says this is not a party political issue as all the mainstream parties are fully behind Net Zero, as he is. He argues a Starmer-led government would be even more determined to push through Net Zero policies.

As locals see it, the whole political class appears to be ranged against the rural community of North Wiltshire, and their votes have nowhere to go on this issue except to fringe parties who have no hope of forming a government. So there is little political pressure on the Secretary of State to turn it down.

Many local residents are furious that big, titled landowners have been secretly in negotiation with Island Green and there are accusations of greed. On several estates, the land being offered for solar development has recently been taken back from tenant farmers. The rent being offered is a closely guarded secret, but sums in excess of £1,000 per acre per year are routinely advertised by renewables companies on the internet, perhaps five times the return that might be expected from farming.

Some farmers have been open in saying that they did not think there was a future in farming any more and this offered a lifeline. Others had been told by the developers that they would be surrounded by the solar complex whether they liked it or not, and had taken the attitude that if they couldn’t beat the development they …

Anti-pylon Brits Could Herald New Off-grid Era

Retired film-maker Christopher Hamblin is unmoved at the prospect of a lump-sum payment from developers to compensate him for electricity towers and cables they want to build near his village in the east of England.

“That’s the trouble with these guys — they know the price of everything and the value of nothing,” says the 86-year-old resident of Ardleigh in Essex, a centuries-old settlement surrounded by some of the country’s most recognisable landscapes.

Hamblin and his fellow residents are part of a growing backlash in local communities across Britain against the expansion of power grids as the steps needed to decarbonise the economy start to encroach on them.

In an attempt to counter this resistance Nick Winser, the government’s electricity networks commissioner, has recommended lump-sum payments to households living close to proposed transmission lines. It was one of several measures aimed at cutting in half the 14 years it takes to complete these projects.

The government wants to decarbonise the electricity sector by 2035, while demand for electricity is expected to double or treble as the economy moves away from fossil fuels under its legally binding target of net zero carbon emissions by 2050. Electric Vehicles and AI data centres have added a crushing new burden.

The offer of cash for pylons (as towers are named in the UK) has not changed the mood in Ardleigh, which is in the path of a new 183km north-south high voltage transmission line that National Grid wants to build through the East Anglian countryside. It would run from Norwich in Norfolk down to Tilbury in Essex and bring in renewable electricity generated from new offshore wind farms.

It is one of several new electricity transmission lines being planned around Britain to move clean electricity often generated in remote coastal locations into more populated areas where it is needed.

The East Anglia plan mainly involves cables carried on 50m-tall pylons dotted across the countryside, including around Ardleigh, which sits on the edge of the protected countryside of Dedham Vale, made famous in the 19th-century masterpieces by local artist John Constable.

The reason for the opposition varies, ranging from blighting the landscape to the impact on farmers or health, but most opponents would rather see the power lines replaced by undersea cables running from the wind farms most of the way down to Tilbury.

“Every single house within that location — we will be in a cage of electricity pylons,” says Chris Whitfield, chair of Ardleigh parish council, pointing out part of the proposed route on a map.

Campaigners are well-organised, learning from other groups across the country, and are prepared to resort to legal action.

Local farm owner Charles Tritton suggested the anger is such that it could hurt the Tory party electorally. “The whole of East Anglia is pretty Conservative,” he said. “Add one or two per cent [swing vote] due to this …

Windy Winter Boating Nights

Richard Stabbins begins an occasional series on the joys and heartbreaks of living on a boat in the middle of a big city.

It’s early evening on the canal towpath and I’m almost home. My hands are frozen and even getting my bike lock open had me yelping expletives. I cut a dishevelled figure on the dark stretch between Broadway Market and Victoria Park, dimly lit by LED lights of neighbouring boats. Hopping onto the bow of my floating home, crouching my way through the front door, my first thought is: “I’m so glad I’ve got a dog!”. Bruno is an excitable 30kg hound, a blessing in himself. I had stocked the stove that morning with a generous heap of coal to keep him warm. It made me love him even more. It’s been 1 degree all day and, boaters returning to a frozen tin box usually despair for an hour or more at the lack of heating that we can monitor from an app on our phone. Praise be, though – I have a hound!

That contentment does not last long. Backpack stowed away in its spot between front steps and cupboard (every boater knows, space is at the key), I set to washing last night’s dishes. I turn on the taps, hear the boiler kick in, and then that splattering sound that every boat-dweller hates to hear: the water tank is empty! I slump down on to my couch made of old pallets and recycled cushions. The serenity of a warm night with dinner and a book is replaced by the knowledge that I must cruise to the nearest waterpoint. Bruno looks on from his bed with eyes that know what’s coming. At least the batteries are full and I’ve got diesel – a (hopefully) short trip like this will use very little fuel.

First things first, I check the weather forecast on my phone. I know it’s cold, but that’s not the biggest factor – it’s the wind. Google says I’ve got two hours before wind speeds really pick up, so that’s my window to get fuel and safely find a mooring spot elsewhere. It wasn’t long ago that I had been awoken at 05:00 by a fellow boater shouting for help. Wind speeds had suddenly hit eighty-plus mph and several boats had come free from their makeshift moorings (their pegs had been dislodged as there are no mooring rings available in that part of Haggerston). One boat had swung around and was resting horizontally across the canal, blocking anything coming through. Four of usin our pyjamas fought the wind and just about managed to heave in the barge Other boats were tied up to the balcony railings of canalised flats. Ropes stretched across the towpath at neck height like deadly rubber bands – a measure taken temporarily to regain some calm and order.

That feeling of …

50-year old Diesel Generator In Mirissa Beach

Mirissa beach is known for cool Eurotrash, beautiful surfing and whale-watching. In common with most of the country outside the dapital, the beach community struggles with an unreliable electricity grid. But it is not known as a centre of off-grid technology – and for good reason. Like most of the country, households in Mirissa depend for backup power on diesel rather than solar. The Perkins generator at the Seastar Hotel is a relatively modern example of a near-century-old design.

It sits in the courtyard of this friendly hotel, maintained by locals, at the end of the long golden beach, that has become increasingly popular over the years.

Western surfers share the waves with Sri Lankan fishermen, who hover near the shore all day, line fishing, while most of the catch is hoovered up by industrial vessels on the horizon.

When the power goes out, about once every couple of days, the huge old generator roars into action. It certainly helped me out when I was trying to go online. Happy Birthday, Generator. You can see the film here.…

Poorest Countries Barred From Building Green Economy

UNCTAD Secretary-General Rebeca Grynspan has issued a rallying call for 2024, in a statement claiming that the rich countries are using the green transition as an excuse to boost their own economies at the expense of developing ones. According to the UN’s trade chief, the world’s advanced economies are greenwashing to make their own eco-credentials look better, while preventing poorer countries from developing quickly.

Grynspan attacked the EU for taking Indonesia to the WTO over its restrictions on nickel exports and requirement to process the ore locally. She said Jakarta wanted to move up the value chain by making products from the nickel. It is only reasonable for a country with an overstretched electricity grid to want to use its own nickel tp produce its own batteries, fro example – rather than being forced to export to China or Canada.

UNCTAD Secretary-General Rebeca Grynspan has issued a rallying call for 2024, in a statement claiming that the rich countries are using the green transition as an excuse to boost their own economies at the expense of developing ones.

“They don’t want it to be exported in the raw form, but with value added. So they were taken to arbitration in the WTO. They lost in the first instance precisely because global trade rules have not been adjusted,” she said. She said that the Agreement on Trade-Related Investment Measures should be reformed. Jakarta has appealed but because the US has blocked the formation of a WTO appellate body, the case has stalled. The EU is considering taking enforcement actions such as tariffs on Indonesian goods. It makes for a “chaotic system” where richer, bigger countries have more power.

“Many trade rules forbid policies that can be used by developing countries. And the developed countries have more fiscal space to subsidise in the areas that are good for ‘quote, unquote’, the environment,” Grynspan, told the Financial Times in an interview.

She said the international trading system, which had allowed states such as South Korea and her native Costa Rica to progress, was no longer working for the poorest. “Trade and investment have been the two pillars for developing countries to really go on to a path of dynamic growth,” she said. But they now face two big problems, locked out of markets by the fast pace of technological change and facing new barriers erected in rich countries. “The least digitally prepared countries are falling farther behind in digital,” said Grynspan. “The other problem is that industrial policy …could affect developing countries’ ability to compete.”

The US landmark Inflation Reduction Act has $369bn of subsidies and tax breaks for domestically produced goods such as electric vehicles. The EU has responded in kind with increased subsidies and policies to stimulate production of silicon chips, critical minerals and green technology. “Developing countries see a lot of these policies as protectionist. They don’t have the …

COP 28 BOSS DITCHES 1.5DEG TARGET

COP 28, lost whatever remained of its credibility today, after revelations this year’s Convenor of the annual Net Zero negotiations told his audience that the target of limiting global warming to a specific target of 1.5 degrees was “not justified by the science.”

This statement, delivered at a fringe meeting on November 11th, was quite a dramatic departure from the script, and will cause huge loss of confidence in all current climate goals and affect the preparations being made by government and corporates.

CoP President A Jaber, who is also head of the UAE state oil company, is emblematic of the way regular COP meetings have been transformed into a Woodstock for green energy capitalists in genera and the oil industry in particular. There are up to 30,000 lobbyists now attending the event, plus tens of thousands of journalists politicians and civil servants. All networking and talking up their own green initiatives, perspectives and plans.

It was Cop 26 that first turned the whole show into the Green Davos. Held in November 2021 under the patronage of the UK’s Boris Johnson, who wanted it to be the perfect meeting of minds between venture capitalists, government and lobbyists, it was the first time that the oil industry lobbyist outnumbered other corporates.

And Al Jaber is correct that Prof Nordhaus, who won the Nobel Prize in 2018 for assessing the costs and benefits of action on climate change, recently concluded that the optimum target for the world to aim for is not 1.5C above pre-industrial levels, but nearer to 3C, which means there may be scope to delay the net zero target beyond 2050.

Other leading scientists on the IPCC – the United Nations own panel of climate experts, agree that the impact of climate change on the economy: “will be small relative to the impacts of other drivers. Changes in population, age, income, technology, relative prices, lifestyle, regulation, governance, and many other aspects of socio-economic development will have an impact on the supply and demand of economic goods and services that is large relative to the impact of climate change.”

There is a now a hope among the fossil fuel lobby that it may be able to seize control of the agenda. Meanwhile John Kerry, the USA’s chief climate negotiator, commenting on Al Jaber’s statement, said he was not there and could not comment on the words used, but assured listeners that the final statement would settle doubts about the continued commitment of the COP process to end fossil fuels.

Shortage of cables means grid delays and rising costs

Every major economy is fighting for supplies needed to expand their electricity grids. Over 80 MILLION kilometers of cable will have to be replaced by 2040 under current decarbonisation plans, says the International Energy Authority.

In the UK alone that is 100 km of heavy-duty overhead cable per DAY from now until 2040. the rate of cable laying is unprecedented – approximately 16 TIMES the rate over the past 30 years. The manpower and the resources do not currently exist.

Demand is pushing up prices, and queues for energy are growing longer. New housing developments in West London are being quoted 10 YEARS, before they can get a grid connection, and the same is happening everywhere.

Britain’s first electricity networks commissioner, Nick Winser, warned in a landmark report earlier this year that the UK would need to connect about four times as much new transmission capacity to the network in the next seven years as has been built since 1990.

To meet this challenge, Britain will need to halve the time it takes to build and install pylons and cables for a new transmission project from 12-14 years to just seven.

He also said existing energy policies were “badly out of date”, and the UK needed a new strategy to shore up its manufacturing supply chain, which would involve training skilled workers.

High-voltage cables and equipment looked set to be in short supply for years or even decades, said Winser, because already producers were struggling to meet demand. As happened with vaccines during the pandemic, companies and even governments will find themselves competing to snap up available stocks.

And skills gaps threatened to “haunt” the UK’s green agenda, he added, unless there was heavy investment to create a new reservoir of trained staff.

Already energy companies have been “scrambling” to secure manufacturing slots, according to Alistair Phillips-Davies, chief executive of SSE. He told the Observer that his company, which has this year committed to investing more than £40bn in green energy and grid upgrades over the coming decade, had secured “around 80%” of the materials it would need for its grid upgrades.

British-owned cable manufacturer XLCC is planning to build the UK’s first factory making high-voltage undersea cables in Ayrshire to help meet demand. Production could begin as early as 2026.

Ian Douglas, XLCC’s chief executive, believes demand for high-voltage cables will increase sixfold over the next seven years, as global use of renewable energy expands. Its first order is from its parent XLinks, for four 3,800km cables to connect solar and windfarms in the Moroccan Sahara to the UK.

“The whole impetus and momentum of net zero risks being hamstrung by a lack of cable,” said Douglas. “The requirement to upgrade the grids is global, and it’s treble what we’re investing globally today.”

The government has accepted the recommendations of Winser’s report, and has already announced steps to …

How often can a LifePO4 Battery recharge a Mac Powerbook?

A new generation of Lithium power stations will transform home and outdoor energy use over the next few years. When you choose a battery, the product description is full of confusing data – so how do you make your choice? Keep in mind that the number of recharges will depend on the battery capacity (expressed in ampere-hours, Ah) of the LiFePO4 battery, and the MacBook’s power consumption. A MacBook 13-inch typically has a battery capacity of around 50-60 watt-hours (Wh). This guide uses the Macbook as an example – the same would apply to any laptop with a similar power consumption and similar-sized battery.

LifePo4 Batteries are widely available and have the following advantages over other technologies –

Long Cycle Life: LiFePO4 batteries are known for their exceptional cycle life. They can typically withstand thousands of charge-discharge cycles, making them ideal for long-term off-grid use.

Deep Discharge Tolerance: LiFePO4 batteries can safely and consistently be discharged to around 80% or even lower without significantly affecting their lifespan. This means they can handle being drawn down to 5% effectively.

High Efficiency: LiFePO4 batteries have a high charge and discharge efficiency, which means you get more usable energy from them compared to some other battery chemistries.

Safety: LiFePO4 batteries are considered safer than some other lithium-ion batteries. They are less prone to thermal runaway and are less likely to catch fire, which is crucial for off-grid installations where maintenance might be less frequent.

Low Maintenance: These batteries require minimal maintenance compared to lead-acid batteries. They don’t need regular topping up with distilled water, for example.

Compact and Lightweight: LiFePO4 batteries tend to have a high energy density, allowing for a compact and lightweight design, which can be advantageous for off-grid setups.

Cost-Effective: While LiFePO4 batteries may have a higher upfront cost compared to some other battery types like lead-acid, their longer lifespan and reduced maintenance requirements often make them more cost-effective in the long run

Here are some recommended batteries with the approximate number of times each battery can recharge a 13-inch MacBook. Keep in mind that the number of recharges will depend on the battery capacity (expressed in ampere-hours, Ah) of the LiFePO4 battery and the MacBook’s power consumption. A MacBook 13-inch typically has a battery capacity of around 50-60 watt-hours (Wh).

Renogy Lycan Powerbox:

Approximate Price: $1,000 – $1,200
Weight: Around 28-30 kg
Battery Capacity: Varies (check product specifications)
MacBook Recharges: Multiple recharges possible

Victron Energy LiFePO4 Battery:
