Spain's electricity demand falls below 2007 levels despite population growth

Spain consumes less electricity than in 2007 with 10 million more people

How is it possible that a country with ten million more inhabitants and more plugged-in devices than ever demands less electricity today than it did almost two decades ago? The official answer is called efficiency. The uncomfortable one is deindustrialization. Data from Red Eléctrica (the Spanish grid operator) places demand below 2007 levels, and the breakdown of what has shut down since then completely divides the diagnosis. This is not a minor nuance: it determines whether we celebrate a cleaner economy or certify structural impoverishment.

The confusing data: less power with more population

The starting point is an arithmetic contradiction. With 10 million more inhabitants than in 2007 and a larger appliance and device park, national electricity demand has not recovered to pre-crisis levels. Some attribute this to the massive shift from incandescent bulbs to LEDs, the renewal of appliances with high energy labels, and improved housing insulation. Cheap windows, the argument goes, are no longer the cold air leaks they were twenty-five years ago, and electric heaters have given way to pellet stoves, catalytic ones, gas, and heat pumps.

The per capita calculation dismantles the celebration. According to estimates circulating in the debate, counting resident population, tourists, and unregistered individuals, consumption per inhabitant has fallen by around 16.5% compared to 2007. Industrial production, meanwhile, stands 20% below its level at that time and at 1995 levels. Efficiency exists, but it does not alone explain such a collapse.

Why is electricity consumption falling in Spain?

Because what actually consumed most has almost ceased to exist. That is the argument running through much of the analysis: heavy industry—metalworks, glass recycling, energy-intensive sectors—is the major consumer, and its share of GDP has fallen from 18% to 11% in twenty-five years, according to the debate. The decline of the secondary sector is not a statistical anecdote; it is the bulk of the explanation.

Against this thesis, the benign version argues that photovoltaic self-consumption has changed the map. Nearly half a million households and some 75,000 companies generate their own electricity, and these flows do not always appear in system demand records. There are industrial warehouses covered with panels operating in surplus. Therefore, the discussion is not just about how much electricity is consumed, but how much is purchased from the grid.

European context: not just a Spanish phenomenon

Germany, France, Italy, Japan, and the United States also consume less electricity than in 2007. The decline is not an Iberian singularity. Compared per capita figures leave Spain with a drop of 17.2%, behind the UK, which takes the lead with a fall exceeding 31%, but ahead of Germany (-7.4%), Italy (-7.6%), and France (-13.23%).

The difference lies in the starting point. Those defending the benign reading note that efficiency arrived via crises: after each recession, the equipment park renews itself suddenly, and consumption drops. Those holding the hard thesis respond that confusing this effect with structural improvement is like mistaking the thermometer for the disease.

Energy poverty: the data that breaks the narrative

Spain leads the European ranking for energy poverty. According to the data used in the analysis, 20.8% of the population cannot maintain their home at an adequate temperature, the highest percentage in the Union alongside Portugal, well above Italy’s 9.5%, France’s 12%, or Germany’s 8.2%. The community average stands at 10.6%.

This data sits poorly with the idea of a country consuming less because it is more efficient. Consuming less because you cannot afford the bill is not sustainability: it is something else. Meanwhile, prices have risen to compensate for the loss of revenue for electricity companies, which distribute less energy but charge more for it, according to the debate.

The industrial bill and the immediate future

The primary and secondary sectors have been the great sacrifices. The destruction of industrial fabric and regulatory pressure on agriculture and mining explain, according to this reading, much of the decline. The result: more expensive food and an economy that produces welfare with less energy, which sounds good until it is verified that welfare is also lower.

The uncomfortable question remains. If consumption falls due to efficiency, why isn’t electricity cheaper for the user? No one has the answer yet. Or perhaps they do, but it is not convenient to say it out loud.
