Is it more expensive to be sustainable? Debunking myths

Sustainability is often associated with an expensive lifestyle. Many people believe that installing solar panels, buying eco-friendly products or investing in energy efficiency is a difficult expense to bear. However, this idea is more of a myth than reality. Today, being sustainable is not only more accessible than ever, but also represents a smart investment in the medium and long term.

Just a decade ago, installing solar energy was reserved for the few. But the landscape has changed radically. According to the International Energy Agency, solar photovoltaics is now the cheapest source of electricity in much of the world. This means that investing in self-consumption at home or in business does not mean spending more, but rather reducing energy costs from day one.

In the case of technologies such as hybrid solar — which combines the best of photovoltaic and thermal energy — the savings can be even greater, as it not only produces electricity, but also domestic hot water and efficient air conditioning.

It is true that many sustainable solutions require an initial investment. Solar panels, efficient appliances, and electric vehicles are not always cheaper at the time of purchase. However, the key lies in long-term analysis: what you pay extra for today will be recouped tomorrow in energy savings, lower bills, and reduced maintenance needs.

A clear example is the electricity bill. An average household that opts for solar self-consumption can reduce its annual electricity expenditure by between 50% and 70%, with a return on investment that usually ranges from 4 to 7 years.

Sustainability does not only have an impact on household or business finances. Committing to clean energy and responsible habits also generates social and environmental benefits: reduced CO₂ emissions, energy independence and increased property values. In many cases, there are also subsidies and public aid available to facilitate the transition to a more efficient and sustainable model.

Sustainability advances hand in hand with innovations that open up new opportunities:

• Smart public and urban projects: Initiatives such as Allocate in A Coruña are promoting ethical and energy-efficient AI to manage mobility, waste and energy in real time, without relying on giant data centres.

• Nanotechnology applied to energy: Materials such as graphene and silicon nanosemiconductors are improving storage capacity and solar conversion efficiency, achieving increases of up to 40% in solar cell efficiency.

• Advanced biofuels: In Cambridge (United Kingdom), solar reactors are being developed that transform CO₂ and plastic waste into clean fuels, an innovative step towards the circular economy.

• Abora Solar leads the way with high-performance hybrid panels: The hybrid solar panel simultaneously harnesses solar energy to generate electricity and heat (domestic hot water), achieving a combined efficiency of 89%, well above the 17-23% of conventional photovoltaic panels. This performance has earned it the first Solar Keymark certification for a hybrid panel, a guarantee of quality and compliance with European standards. Thanks to its dual energy production and high performance, Abora’s PVT generates the equivalent energy of four photovoltaic panels in the same space, multiplying profitability and savings per square metre. The return on investment is usually achieved in 4 to 6 years, or even sooner depending on the type of installation, especially hotels, residences or facilities with high hot water demand.

The myth that ‘being sustainable is expensive’ is debunked when the data is analysed with perspective. The reality is that opting for efficient solutions such as solar energy is not a cost, but an investment in the future. An investment that protects the planet, improves quality of life and, above all, helps save money.

In short, being sustainable is increasingly profitable. And the sooner you take the plunge, the sooner you will enjoy the benefits.
