The Ministry of Housing, Communities and Local Government has recently launched an operational review of the Nationally Significant Infrastructure Projects (NSIP) regime. This regime, established in 2008, was put in place to bypass local planning approval for projects that had a predominately national rather than a local impact.
Over the last few years, the regime has taken a significant battering with ‘development consent’ (the granting of planning approval) for major infrastructure programmes being brought before court due to the corresponding National Policy Statement (used to determine if a project is in line with government ambition) being out of date with latest government policy. The most notable example being a third runway at Heathrow. This highlights that something is wrong with turning strategic policy intent into decisions on granting development consent.

640K Ought To Be Enough for Anybody
That infamous statement—whether Bill Gates said it or not, goes to show the change in computing and the demands on the semiconductor industry over the last 40 years. At the beginning of the ‘70s, there was no expectation that the personal computer could become an affordable item for the man in the street. By 1979, however, Atari had released the 400 and 800 series of home computers. Three years later, the Commodore 64 made its debut, featuring 64KB of RAM and using an 8-bit CPU.
In 1977 Steve Wozniak designed the Apple II, an 8-bit home computer. Launched at the 1977 West Coast Computer Faire, it was aimed at the home consumer market rather than the business market.
August 12 1981: The IBM PC
It could be argued that the first non-Apple PC, as we've come to know it, was the IBM 5150 personal computer. Its success spurred the production of IBM clones, or IBM PC compatible computers, with Columbia Data Products (CDP) producing the first in June 1982.
A Case of History Repeating Itself?
In the early ‘80s, anticipating the demand for PC’s to continue, memory chip manufacturers ramped up the production of RAM. But by September 1985, the market had stagnated, and a DRAM chip could be bought for $2.95. Demand for computers had slumped, and this low price reflected industry slowdown and extreme overproduction.
Roll On To 1988 and the Price of Computer Chips Rocketed
With a glut of existing RAM chips in the marketplace, manufacturers were cautious of the overproduction of 256-kilobit DRAM chips and converted their factories for 1-megabit chips.
This shows that chip producers drastically misread the market. 1-megabit chips took significantly longer to manufacture, and so before too long, there was a shortage of RAM, causing prices to increase.
The situation began to improve by the next year. Since then, although there have been years when supply was affected, it has been nowhere as catastrophic as now.
The Current Semiconductor Chip Crisis
We are facing an unprecedented shortage of semiconductor chips which is affecting worldwide markets. COVID-19 undoubtedly had a massive influence on this, but the demand for microchips was already soaring.
2019 COVID-19 Appears
Although in November of 2019, a person displayed the first detectable case of COVID-19 in China, there was little else to warn of what was about to come. In the following months, as cases increased, so did hospital admissions. With the horror of widespread deaths, we saw countries bringing in protective measures and restrictions. These became increasingly severe and ranged from social distancing to working from home. This had a direct effect on the industry, seeing output slowed or temporarily ceased.
2020 Onwards
In February of 2020, the indirect effects of the pandemic began to bite. Companies closed offices or limited the number of onsite staff. Employees were also encouraged to work offsite where possible. Other employers were forced to furlough employees. For some, the concept of working from the home kitchen table became a daily reality. This was seen as essential to ensure that services were maintained, albeit at a reduced capacity.
For factory-based and hospitality industries, the impact was more dramatic.
Company Employees Working From Home
The decision by many companies to encourage staff to work from home was a direct result of COVID-19 and the resulting Government restrictions, but this, in turn, caused an indirect effect on the semiconductor shortage.
In some cases, employees might have had existing company laptops issued to them for use in the workplace. In other cases, the use of their personally-owned device might have been sanctioned for company work. But in other circumstances, the company would either pay the employee to upgrade their laptop or provide a new company laptop with the necessary application and security software installed.
This added to the general increased demand for computers that had computer manufacturers struggling to procure chips.
Furloughed Employees
Many furloughed employees suddenly finding themselves trapped at home with limited opportunities (if any) for socializing turned to or spent more time on gaming.
This fuelled an interest in the latest products on the market and a keen appetite for products about to be launched. In turn, manufacturers clamored for more chips.
Home Schooling
Schools and colleges rose to the challenge of providing continuing education for their pupils and turned to online teaching when the school buildings were closed. Children were being home-schooled by parents and following online lessons. But it was essential that the children had the necessary resources. The basic requirements were a laptop with a webcam and a reliable internet connection. Subsequently, laptop sales increased dramatically.
Who Is Taking The Hit?
A simple answer is— any industry whose products depend on a high level of semiconductor chips, but in particular, the main players feeling the pain are the automotive and consumer electronics markets.
The Auto Industry
Automotive Companies Fall To the Back of the Semiconductor Chip Queue
As COVID-19 began to take a grip, and with falling demand for vehicles, auto manufacturers either closed sites temporarily or reduced operations. Subsequently, they scaled down backorders from semiconductor suppliers. Meanwhile, the consumer electronics market was thriving and crying out to suppliers for more semiconductor chips.
Later, when manufacturing was resumed, auto manufactures found themselves at the back of the queue.
What Chips Are Used In Motor Vehicles?
There are various types of chips used by auto manufacturers in their vehicles, ranging from commodity chips to microprocessors.
According to Statista, “Infineon, NXP, and Renesas were the leading automotive semiconductor manufacturers worldwide in 2020. Infineon's market share was estimated at around 13.2 percent. The total market in 2020 was sized at around 35 billion U.S. dollars.”
The Domestic Market (Consumer Electronics)
Broadly speaking, this sector covers anything that falls into the entertainment, communications, and recreation categories.
Although visits to high street stores to make purchases proved difficult, if not impossible during lockdown periods, online sales soared. But this boom has caused manufacturers a headache, as launches of new products have had to be delayed and fulfilment of the demand for existing models could not be met due to the chip shortage.
Other Contributory Factors to the Crisis
Although COVID-19 disrupted chip manufacture by causing foundry shutdowns and the halting of production, it wasn’t the only factor. An already beleaguered market was battered by other factors compounding the chip shortage crisis.
Drought in Taiwan
Water, a major necessity for semiconductors production, has been in short supply due to the worst drought in 56 years.
Suez Canal Blockage
In March 2021, the 400-metre-long (1,300ft) container ship ‘Ever Given’ ran aground in the Suez Canal and blocked the channel for six days, further impacting distribution and supply.
Factory Fire
Japanese chipmaker Renesas Electronics Corp. the world's third-largest supplier of automotive chips suffered a fire at its factory.
Severe Weather Conditions in Texas In February
Samsung, NXP, and Infineon chip fabs shut down in Texas amid record storm.
Why Not Just Produce More Chips?
While attempting to address the global chip shortage as expeditiously as possible, semiconductor manufacturers cannot afford to make a knee-jerk reaction. If fabrication plants are at maximum capacity or are only structured to make one type of chip, why not build more fabs?
Semiconductor wafer fabs are hugely expensive to build. It takes considerable time to construct a new fab, with some as large as small cities. These fabrication plants, also known as foundries, require highly controlled environments where temperature, humidity and static electricity are controlled, and dust-free environments are guaranteed. As an immediate response, building new fabs is not a practical solution to the problem. Long term strategies will have to be put in place as the whole situation is addressed.
When Will The Global Chip Shortage End?
There are differing views being expressed on this tricky question. Some are optimistic, considering that the worst of the situation is over. Others provide a gloomier outlook, warning that we could be experiencing shortages well into another two years.
Crisis management expert Edward Segal writing in Forbes: “The semiconductor chip crisis that hit companies around the world shows no signs of ending any time soon and will continue to impact the supply chains for many industries. Indeed, some organizations have yet to fully recover from the impact of the blockage of the Suez Canal last March on their ability to send and receive essential materials, parts and supplies.”
Are There Any Lessons To Be Learned?
A cynical reply might be—expect the unexpected.
Of course, it is impossible to predict and plan for every possible eventuality. Changing market trends should be anticipated, whereas something as unforeseen as a global pandemic cannot. Manufacturers, however, should seriously take a look at their contingency plans.
It seems that far and above the other problems of the chip crisis, the biggest headache within the semiconductor industry is the supply chains.
Distribution Networks
Writing in an article for ZDNet, Daphne Leprince-Ringuet: “The semiconductor supply chain is flawed, and it's going to take a long time until things get better, despite the combined efforts of industry and regulators.”
Supply chains are the highways of trade upon which product delivery depends. But the semiconductor supply chain is hugely complex and is spread across several countries. Admittedly, it is essential to create more fabs over the following years. Still, it is critical to maintain a watchful eye on supply chain policies to ensure future semiconductor chip demand fulfilment.
Just-In-Time (JIT) Model
Considered as an effective approach by some automotive manufacturers as an efficient method of business management in times of plenty. It becomes counterproductive in times of shortage when they will face long chip manufacture lead times.
Chip manufacturers are advocating a greater knowledge of their customers’ production maps, stating that even a two quarter indication is insufficient for planning.
Think Outside The Box
Be open to some lateral thinking. Recycling could be an interim response to chip shortage.
All Of A Sudden Vintage Equipment Is A Hot Commodity
Steven Zhou writing in Forbes, reports that old (obsolete) fabs could be suitable for the production of some current 'smart' devices.
While the creation of extra fabs can take over two years and the building of the manufacturing equipment up to eighteen months, repurposing old equipment could be a source of additional capacity.
Reliance On Asia
The current crisis has brought about an awareness of the inadvisability of an ongoing reliance on Asian fabs for the supply of semiconductor chips for U.S. and European markets.
The Future
According to the Semiconductor Industry Association (SIA) in a publication Strengthening The Global Semiconductor Supply Chain In An Uncertain Era “Over the next ten years, the industry will need to invest about $3 trillion in R&D and capital expenditure globally across the value chain in order to meet the increasing demand for semiconductors.”
Moore’s Law Is Not Dead
Moore's law is the premise first expressed in 1965 by Gordon E. Moore, the co-founder of Intel, that the number of transistors on a microchip doubles every two years, though the cost of computers is halved. Or put another way—that we can expect to see larger-scale integration with more circuitry packed into chips for the same form factor.
If this proves true, manufacturers will take advantage of these cheaper and more advanced chips to develop a new generation of products that consumers will be only too eager to buy.

The Office for Budget Responsibility (OBR) in its latest Fiscal Risks Report has forecast the cost to the UK public finances from climate change (physical risks) and the transition to net-zero (transition risks) across a range of different scenarios.
Describing the challenge, the OBR states:
There are many other policy challenges to overcome, so the path to net zero can be expected to involve many policy levers on top of carbon taxes and emissions trading schemes, including bans and other regulations, and public subsidies and investment. These will all have economic and fiscal implications of one sort or another – either directly (via taxes and spending) or indirectly (via wider economic outcomes).
Taking early action to achieve net zero would add 21% of GDP to public sector net debt by 2050, a smaller amount than that added by the Covid-19 pandemic. This amount comes from increased spending on net-zero investment, the loss of tax revenues (such as fuel duty), revenues from tax on carbon and other costs such as increased debt interest payments.
