As AI fever runs high, BBC reported a US-based start-up, Digital Realty that plans to use small nuclear reactors to power their AI data center in Portland, Oregon. But why?

In an interview with BBC, Stephanie Hare, an AI commentator and technology researcher, said that powering data centers in general are very energy-intensive, leaving behind a massive carbon footprint in addition to the usage of water.

Gallons of water, for instance, functions as a coolant to counteract overheating in machines when it busy processes user requests.

Hare noted that computers there can use up to ‘half a liter’ of water to process requests from a single user at a time.  

However, operating an AI data center is going to consume even more power.

“A normal data center needs 32 megawatts of power flowing into the building. For an AI data center it’s 80 megawatts,” said Chris Sharp, Chief Technology Officer (CTO) of Digital Realty, to the BBC. But it’s not just Digital Realty though participating in this enterprise.

Small Modular Reactors can generate one-third the energy of a conventional nuclear power plant and are said to be cheap based on design.

In 2023, The Verge reported Microsoft potentially showing interests in using ‘small modular reactors’ (SMRs) to fuel their AI data centers. These reactors split uranium nuclei with slow-moving neutrons, very much like conventional nuclear power plants.

However, lending a nuclear reactor to commercial establishments comes with its challenges. For one, only skilled workers can be relied upon to operate properly and manage the nuclear reactor.

Whereas for another, is for the nuclear reactor with its safety mechanisms to manage waste. However, scientists at Stanford University and University of British Columbia had worked out some technical flaws in SMRs. They reached the opposite conclusion to what SMR advocates had to say. They said there’s going to be more radioactive leakage owing to the small design that can’t absorb and take away byproduct neutrons from the chain reaction.

However, these generate one-third the energy of a conventional nuclear power plant and are said to be cheaper to design and manufacture. But how soon can they be deployed?

In the US, their Nuclear Regulatory Commission has authorized one such SMR design, by NuScale although it will be demonstrated only in 2029.

Spencer Lamb, Chief Commercial Officer at British data center developed Kao Data, said in the same BBC report, “I’ve heard about SMRs, but it will take a long time to deploy a nuclear-configured data center in the UK, and AI is happening now.”

BBC interviewed Dr Doug Parr, who’s chief scientist of the non-profit environmental activist group, Greenpeace UK, who labeled the unfolding story about SMRs powering AI data centers as mere ‘hype’. He said tech companies will develop cold feet when they realize that SMRs would prove to be much costly when they’re finally demonstrated. “Unrealistic hype lies behind the cost estimates for SMRs,” said Dr Parr. “This hype will fall away as delays and difficulties emerge.”

However, Dr Michael Bluck a nuclear engineer at Imperial College London, UK was more optimistic – at least in a technical standpoint. He said, “There’s no reason why a small fast reactor can’t power a data center, except that you have to get it past the regulator.”

What about public trust though? The BBC doesn’t cover that. Won’t they have the final say in this case, since it involves nuclear energy? At least in history, nuclear energy has been a point of contention in the West, with public suspecting whether authorities were truly capable of ensuring safeguards against radioactive leakages and waste management. In Germany, policy failure to reassure the public actually led to the wide-spread phase out of nuclear reactors. Public trust is hard to achieve, but it takes the government and scientists to trust them back.

In the UK back in 1957, local farmers in Cumbria, England had suspected radioactive leakages from the Sellafield nuclear plant. However, authorities and scientists didn’t pay attention to the farmer’s concerns of a leak, until farmers strenuously lobbied to get the site checked for by scientists – later positively verifying the claims, leading to the shutdown of the plant.

The point isn’t that nuclear energy is somehow more unsafe compared to other forms of energy, say renewable energy. The numbers of countries operating nuclear reactors have actually expanded to 32 countries, including developing countries, with some 436 reactors operational of today.

Yes, catastrophe has occurred in the past – there’s the infamous Chernobyl and Fukushima events. The US alone had witnessed the Three Mile Island nuclear disaster in 1979. But we don’t want that to happen again.

The point is – paradoxically – we’ll never know how safe a technology is, unless we’ve already tested them.

But before that we need to keep the dialogue on as we discuss and discover hidden risks.

The coastal winds of Tamil Nadu swept across the lush green fields, carrying with them the promise of a cleaner, more sustainable future. As the sun dipped below the horizon, the turbines that dotted the landscape turned steadily in the breeze, their blades slicing through the air like symbols of progress. In this southern state, a renewable energy revolution was taking root—one that would power not only the homes of millions but potentially reshape the future of global energy.

This transformation is not just a story of Tamil Nadu; it is the story of India, a nation rapidly advancing toward its renewable energy goals, with states like Rajasthan, Gujarat, Tamil Nadu and Karnataka playing a pivotal role in that progress. In October 2024, India’s renewable energy capacity soared past the 200-gigawatt (GW) mark, solidifying the country’s position as a global leader in clean energy. This milestone marks a critical point in India’s journey, as it works toward its ambitious target of 500 GW of renewable energy capacity from non-fossil sources by 2030.

As of 2024, Tamil Nadu boasts a renewable energy capacity of 23.7 GW, much of it derived from its wind farms. These wind corridors, stretching across the coastal plains, are among the most productive in the world. The state is also a major player in solar energy, leveraging its abundant sunlight to complement its wind resources and create a well-rounded renewable energy mix.

Tamil Nadu’s approach to renewable energy reflects a larger national trend. India, with its vast land, diverse climates, and abundant natural resources, is uniquely positioned to lead the global renewable energy revolution. The country’s total renewable energy capacity has surged by 24.2 GW in just a year, reaching 203.18 GW by October 2024. With wind, solar, hydro, and bioenergy resources contributing to this capacity, India is moving steadily toward its goal of energy independence and environmental sustainability.

Harnessing the Winds of Change

From sprawling solar farms in Rajasthan to the wind farms off Tamil Nadu’s coast, India has carefully cultivated a diverse renewable energy portfolio. The surge in renewable capacity includes an impressive 92.12 GW of solar power, 47.72 GW of wind energy, and 46.93 GW of hydroelectric power. With the addition of bioenergy resources, including biomass and biogas, which contribute 11.32 GW, India’s renewable energy landscape is not just growing—it’s evolving into a robust, multifaceted powerhouse.

The International Renewable Energy Agency (IRENA) reported that India accounted for a substantial portion of the 16.2 million jobs in the global renewable energy workforce.

This progress is not just about reducing India’s reliance on fossil fuels—it’s about securing the country’s energy future. In 2024, non-fossil sources, including nuclear power, now account for nearly half of the total installed electricity generation capacity, a figure that marks an essential step in India’s journey toward energy security and global environmental leadership.

The Winds of Change: How Renewable Energy is Powering Job Creation

But India’s renewable energy revolution isn’t just about the environment—it’s also driving economic growth. In 2023, the sector created over 1 million jobs, with hydropower and solar power leading the way in employment opportunities. The International Renewable Energy Agency (IRENA) reported that India accounted for a substantial portion of the 16.2 million jobs in the global renewable energy workforce. In particular, hydropower alone provided over 450,000 jobs, while solar energy employed approximately 318,600 people, a number that continues to grow.

As India’s renewable energy sector expands, so too does the potential for more green jobs. From construction and installation to operations and maintenance, the job opportunities created in this sector are helping to power not just the economy, but the livelihoods of millions of people across the country.

Leading the Charge: India’s Global Climate Commitment

India’s renewable energy achievements are a testament to its unwavering commitment to addressing the global climate crisis. Under the Paris Agreement, India has made bold promises to reduce its emissions and transition toward a low-carbon economy. By 2030, the country has committed to cutting its emissions intensity by 45% compared to 2005 levels, and to sourcing 50% of its cumulative power capacity from non-fossil sources.

These targets align with India’s long-term strategy to reach net-zero emissions by 2070. The nation’s efforts are rooted in the principle of equity, recognizing that the fight against climate change must account for the differing capabilities and responsibilities of countries around the world.

India is not just a participant in the global effort to fight climate change—it is emerging as a leader. The country’s growing renewable energy sector is proving that it’s possible to combat climate change, secure energy independence, and create millions of green jobs in the process.

India’s Renewable Leaders

While India’s renewable energy revolution is a national effort, certain states have emerged as leaders in driving the country’s green energy push. Rajasthan, with its vast land and abundant sunlight, leads the way with 29.98 GW of installed renewable capacity. Gujarat follows closely with 29.52 GW, bolstered by the state’s aggressive solar and wind energy policies. Tamil Nadu, with its coastal wind corridors, contributes 23.7 GW, while Karnataka rounds out the top four with 22.37 GW.

These states are not just providing energy—they are setting the stage for India’s renewable energy future, serving as models for other regions to follow.

The Road Ahead: A Green Energy Future

As India celebrates the achievement of over 200 GW in renewable energy capacity, the country stands at the threshold of even greater accomplishments. With its eyes set firmly on the target of 500 GW by 2030, India is positioning itself not only as a leader in renewable energy but also as a key player in the global fight against climate change.

Government initiatives such as the National Green Hydrogen Mission, the PM-KUSUM(Prime Minister’s Scheme for Farmers’ Energy Security and Upliftment )scheme, and the Production-Linked Incentive (PLI) program for solar photovoltaic modules are all part of India’s broader strategy to enhance its renewable energy capacity and reduce its dependence on fossil fuels.

India’s renewable energy journey is far from over—but the path ahead is clear. By continuing to invest in solar, wind, hydro, and bioenergy, India is not just meeting its energy needs; it is setting an example for the rest of the world to follow.

In the fight against climate change, every gigawatt matters. And India is proving that, when it comes to renewable energy, the world can count on it to deliver.

How the Same Customer Can Bring You More Revenue

You walk into a car showroom, intending to buy the base model of a car, considering your budget constraints. The sales executive shows you the car, explaining its features in detail. He then suggests, “Sir, why don’t we also check out the next variant?” Intrigued, you follow him to the upgraded model and listen as he elaborates on its extra features. You find it much better than the car you initially intended to buy, and eventually, you decide to purchase the higher variant.

The strategy employed by the sales executive here is known as “upselling.” He successfully persuaded you to spend more money on a more expensive model than you originally planned. This is similar to a customer intending to buy an Apple iPhone 16 but ending up purchasing the Apple iPhone 16 Pro Max instead. Or when you walk into a pizzeria intending to have a small pizza but end up ordering a medium or large one due to the server’s convincing pitch. These are all outcomes of effective upselling.

Now, let’s look at another scenario. You enter a restaurant and order a masala dosa, a popular South Indian dish. When the waiter serves your dosa, he also places a vada (a savoury, deep-fried snack commonly found in South Indian cuisine) on the plate. Hungry, you eat both the dosa and the vada, pay the bill, and leave. Though you could have simply eaten the dosa, the restaurant managed to sell you an additional product.

This technique is known as “cross-selling.” The restaurant sold you a vada alongside the dosa you initially ordered. Similarly, when you order a product from Amazon, you often see a message like, “Customers who bought this also showed interest in these products,” accompanied by pictures of related items. Amazon is effectively cross-selling to you.

Both upselling and cross-selling can be applied in any business. Employees should be trained in these strategies, and attractive offers and discounts should be provided to customers

These are two effective strategies in sales. A retailer can sell a bedroom set to a customer who came to buy a cot or mobile phone accessories to someone purchasing a phone. Similarly, a tile showroom selling sanitary products, hardware, and electric fittings follows the same principle. The goal is to get the same customer to buy more products and thus increase sales.

Both upselling and cross-selling can be applied in any business. Employees should be trained in these strategies, and attractive offers and discounts should be provided to customers. For example, offering three t-shirts in different colours for $18 instead of one for $7.20 is likely to attract more buyers. Let’s start implementing these tactics to boost our sales.
