Does a laptop consume half as much as a desktop computer?

How much energy does a computer consume?

The truth is that it depends a lot on the type of computer, its components and, above all, how it is used.

A mid-range computer used for about 2 hours a day does not consume the same energy as a very high-performance "gaming" computer used over prolonged periods.

In addition, the miniaturisation of technology and increasing energy efficiency have meant that laptops have evolved significantly in recent years. Something which, without any doubt, means significant savings for your pocket and lower CO₂ emissions into the atmosphere.

The differences between laptops and desktops is evident, and it is estimated that even the most efficient desktops still consume ten times more electricity than the best laptops.

Of course, desktops continue to outperform their smaller brothers due to advantages such as ventilation, a key element that influences its useful life, since the motherboard generates a lot of heat. This means, the better the ventilation, the less energy consumed by the computer, the less heat generated and the less wear and tear.

Despite the fact that laptops have considerably improved their cooling systems, they continue to overheat, draining battery life, shortening the time between recharges and increasing energy consumption.

So, desktop or laptop?

If we are talking about electricity consumption, it is evident that laptops win most of these battles against desktop computers.

However, if we consider other factors, such as ventilation, durability, robustness and the possibilities for upgrades and customisation, the answer becomes more complicated.

In short, each one has its own features and energy needs, and the choice depends on the use we put them to and power that we need in each case.

This last point will be the one that will tip the balance when choosing between a desktop or laptop.
