Cold Beer and Hot Showers - Not Kilowatt-Hours All That Consumers Want The energy sector spends an extraordinary amount of time talking about generation, transmission, storage, flexibility, markets, tariffs, balancing, ancillary services, carbon emissions, batteries, hydrogen, demand response, electrification pathways, system costs, capacity mechanisms, investment signals, market design and regulation. All of these things matter. Some of them matter enormously. But there is a simple question that often disappears somewhere between the conference room, the policy paper and the technical model: What does the customer actually want? The answer is surprisingly simple. Most people do not wake up in the morning thinking about kilowatt-hours. They do not dream about capacity markets. They do not worry about frequency stability. They do not spend their evenings comparing balancing mechanisms. They want cold beer and hot showers. They want a warm home in winter and a cool home in summer. They want the lights to turn on when they press the switch. They want their phone charged, their food refrigerated and their car ready when they need it. In other words, they do not want energy. They want what energy allows them to do. That distinction may sound trivial, but it changes almost everything. For more than a century, the energy industry has been organized around the production, transportation and sale of energy itself. Electricity became measured in kilowatt-hours. Gas became measured in cubic meters. Fuel became measured in litres or tonnes. Markets, regulations and business models were built around those units. The customer, however, never experienced life in kilowatt-hours. The customer experienced comfort. Convenience. Mobility. Reliability. Security. The units used by the industry and the outcomes desired by the customer were never the same thing. For a long time, this mismatch was not particularly important. Energy was relatively scarce, flexibility was limited, and the dominant challenge was supplying enough fuel to satisfy demand. The system could afford to focus on production because production was the central problem. Today the situation is changing. Electrification is transforming energy systems around the world. Renewable generation is increasing rapidly. Batteries are appearing in homes, businesses and vehicles. Buildings are becoming smarter. Heat pumps are replacing boilers. Electric vehicles are becoming mobile storage assets. Customers are increasingly able not only to consume energy but also to store it, shift it, manage it and sometimes even sell it. As this happens, the most valuable question is no longer simply how much energy is produced. The more important question becomes: How well is energy aligned with what people actually need? A family does not care whether its water heater operates at noon or at two in the afternoon if hot water is available when someone steps into the shower. A homeowner does not care whether a battery charges at 1 p.m. or 3 p.m. if electricity costs less and reliability improves. An electric vehicle owner does not care when charging occurs as long as the vehicle is ready when needed. The objective is not the kilowatt-hour. The objective is the service. This is why many of the most important developments in modern energy systems are not really about producing more energy. They are about matching energy to the service required, at the right time, in the right place and in the right form. The technical term for this is often hidden behind complicated language. Experts discuss flexibility, demand management, dynamic pricing, distributed energy resources and system optimization. Consumers experience something much simpler. They experience agency. They experience the ability to save money without sacrificing comfort. They experience the ability to make choices. They experience the ability to benefit from technologies that work for them rather than asking them to work for the technology. This is where many debates become confused. Consumers do not want to be coordinated. They want agency. Good energy systems do not force people to behave differently. They make beneficial behaviour easier, more natural and more rewarding. The best systems do not rely on control. They rely on alignment. When the customer’s interest aligns with the system’s interest, remarkable things become possible. Demand shifts naturally. Storage becomes useful. Flexibility appears. Costs decline. Reliability improves. The customer does not need to understand the complexity underneath. Just as nobody needs to understand how the internet routes packets around the globe in order to send a message, nobody should need to understand wholesale electricity markets in order to enjoy affordable energy services. Success is not measured by how much complexity consumers are asked to absorb. Success is measured by how much complexity the system absorbs on their behalf. The future energy system will undoubtedly involve more digital technology, more electrification, more storage, more automation and more coordination. But none of those are the destination. They are merely tools. The destination remains exactly what it has always been. Cold beer. Hot showers. Comfortable homes. Reliable mobility. Affordable bills. Everything else is infrastructure. And perhaps that is the simplest way to understand the energy transition. People do not want kilowatt-hours. They want the life that kilowatt-hours make possible.
