Renewable Energy Powers More than 70% of Portugal’s Electricity

Portugal creates more than 70% of its electricity from renewable sources. Its solar, wind, and hydropower output place the country among Europe’s cleanest electricity producers.

In September 2026, 70.8% of Portugal’s electricity production came from renewables. While between January and September, renewables accounted for 74.1%, according to APREN (Associação Portuguesa de Energias Renováveis).

For property buyers, renewable energy can reduce electricity costs, boost long-term values, and improve energy independence. Here’s what the numbers mean for real estate investors and what to look for in an energy efficient home in Portugal.

Renewable Energy Accounts for Over 70% of Portugal's Electricity Production

Portugal generated 70.8% of its electricity from renewable sources (or 2,336 GWh out of 3,300 GWh) from 1 to 30 September 2026, stated the Portuguese Renewable Energy Association (APREN).

However, this was not an isolated event.

From 1 January to 30 September 2026, Portugal produced 74.1% of its energy from renewables. In fact, Portugal ranked fourth among European countries, behind Norway (97.6%), Denmark (95.2%) and Austria (80.8%).

There was a time when Portugal could supply its entire country’s demand for electricity through its renewable sources. That occurred in September for a total of 8 hours. During the first 9 months of 2026, Portugal registered 715 such hours spanning across different days, which is almost the same as 30 full days.

But this data doesn’t mean that over 70% of the total electricity consumed in Portugal that month came from renewables. Based on REN (Rede Elétrica Nacional), Portugal met 52% of its electricity demand with domestic renewable energy and another 35% with imports.

Electricity demand in Portugal is also increasing. REN saw record numbers in the first 9 months of 2026, with the demand in September skyrocketing by 6.8% than the same month the year prior.

What Portugal's Renewable Energy Growth Means for Property Buyers

Portugal’s renewable energy growth creates extra benefits for the country’s real estate market. It supports sustainable, energy-efficient, and modern builds, while also creating new investment opportunities for commercial and residential property buyers.

Lower electricity bills

One of the biggest advantages of sustainable housing in Portugal is their potential to decrease everyday energy consumption.

Cooling, heating, lighting, and water heating make up a major portion of the household’s monthly expenses. A home that is more energy efficient and properly insulated can reduce energy loss.

Good long-term value

As more investors, buyers, and renters become more eco-conscious, the demand for energy-efficient properties can soar.

Buying a property in Portugal that’s equipped with energy-saving lighting, double-pane windows, quality insulation, and modern cooling and heating systems can increase its resale value.

Potential for stable rental income

Sustainable properties in Portugal can enjoy higher rents. Many tenants are eager to pay a premium for living accommodations that align with their ecological values and reduce the running costs.

Lower maintenance costs

Older properties often require higher costs for real estate maintenance in Portugal. An energy-saving home already has appliances that can reduce carbon footprint and conserve energy. Therefore, buyers often face lower costs for renovation.

How to Check the Home's Energy Efficiency Before Buying

Two properties of the same size can have very different energy requirements based on their overall design, insulation, heating, and cooling systems.

Here are a couple of tips that buyers can use to evaluate a home’s energy efficiency:

• Home design: Consider the layout, orientation, and ventilation of the property. Exterior shading and well-positioned windows can affect how much heat enters the property.
• Insulation: Look for any signs of damage to the walls, floors, or roof. Structural damage begins with load-bearing components and can show visible patterns.
• Doors and windows: Older properties often have air leakage, while modern designs can have quality seals, coating for thermal performance, and double-glazed layers.
• Cooling and heating systems: Find out the type of system the property uses. Look at the installation date, energy-efficiency rating, maintenance, or replacement history.
• Major appliances: Investigate the efficiency and age of appliances, such as ovens, washing machines, refrigerators, pool equipment, clothes dryers, etc.
• Solar production: Properties with solar panels in Portugal can provide different energy profiles than those without them. If there is solar equipment, check whether it is leased, financed, owned, or subject to an agreement.
• Energy bills: Previous energy bills show a clear cost pattern between different seasons. Buyers can see how the household’s usage and occupancy affect the overall expenses.
