No nuclear, no coal
Portugal has made significant strides in integrating renewable energy sources into its electricity generation. The country has taken advantage of solar power, tidal power wind generation, and hydroelectric power plants. Portugal is becoming a World leader in developing every form of energy independence. At the end of 2021, Portugal became coal-free after shutting down its 628MW Pego coal-fired power plant, privately owned by utility Tejo Energia. Pego's closure came just ten months after the shutdown of the 1,250MW Sines coal plant, owned by national utility EDP. No nuclear, no coal-produced power. Sometimes the progress passes our attention, but we should be aware of the significant progress Portugal is making.
Sustainable energy practices have become a key focus for many countries worldwide. With the increasing awareness of climate change, countries are looking for ways to reduce their carbon footprint and transition towards renewable energy sources. Portugal has been a leader in sustainable energy practices, setting ambitious targets and implementing policies to achieve them. I have looked at Portugal's approach to sustainable energy practices, compare it to other EU countries, and look at the challenges faced by these countries in transitioning to sustainable energy.
Significant progress
Portugal has made significant progress towards achieving its renewable energy targets, with renewable energy sources accounting for 54% of its energy consumption in 2019. This is higher than the EU average of 18%. Latest figures claim that the figure is now at 60%. Portugal has also invested more in renewable energy sources than many other EU countries, particularly in wind and solar power. However, Portugal faces challenges in transitioning to sustainable energy practices, including the high cost of renewable energy projects and the need for infrastructure upgrades. Other EU countries face similar challenges, with some countries lagging behind in achieving their renewable energy targets.
More than a trend
Portugal seems to understand that sustainability is more than a trend, it is a vision towards the future. In the last decade, investing in this strategic development path has been seen more like a moral obligation for both entities and companies, as well as a way of achieving a positive advancement for their economy. Portugal has carried out remarkable progress in this field until becoming a country leader in the renewable energy transition. Quite an achievement for a small country.
In January 2022, 4,085 GWh of electricity were generated in mainland Portugal, where 63.64% came from renewable sources being 31.27% wind, 17.78% hydro, 6.99% bioenergy, 3.80% solar and 3.80 pumping. However, Portugal still remains reliant on imported gas, as the remaining 36.36% came mainly from natural gas, which accounted a 31.27%. All of Portugal's natural gas is imported, mainly from Algeria (via a pipeline that transits through Spain) and from Nigeria (LNG). We are not reliant on President Putin!
Portugal has set ambitious targets for renewable energy, aiming to achieve 80% of its energy needs from renewable sources by 2030. To achieve this, Portugal has implemented several policies, including feed-in tariffs, tax incentives, and subsidies for renewable energy projects. Portugal has invested heavily in wind, solar, and hydroelectric power, and now tidal power. In addition, Portugal has implemented energy efficiency measures, such as building codes that require energy-efficient buildings and the use of smart grid technology to manage energy consumption.
Energy-efficient buildings are a major factor for people, many of whom seem to believe that all construction is seriously inadequate in this area. This is simply not true. Older buildings were, and still are, very basic and subject to damp, cold and excess heat in the summer. But go back 100 years or more and look at traditional buildings. These are frequently built with very thick walls, and a minimum of windows, and are quite effective at keeping both warm and cool at the appropriate times of the year. If you are looking at an old farmhouse or country building, then you will need to look very seriously at bringing insulation up to date. Older local buildings do suffer from dampness, not least as they have no efficient ventilation. I live in a property about 15 years old, it has cavity walls filled with foam. We don’t have damp, it has double glazing as standard, although we needed to upgrade this, and is warm in the winter and cold in the summer, aided with efficient air conditioning with heat pumps, which are widely available. The UK is still trying to legislate to get homeowners to install heat pumps, but here in Portugal, these are standard.
Over the last ten years, France, Italy, Spain and Portugal – have seen the highest rate of heat pump installations, with the number of annual installations per household more than doubling over a decade.
Still reliant on imported electricity
Portugal still needs to import electricity, mainly from Spain. However, Portugal also exports electricity. In 2021, Portugal imported $1.47B in electricity, becoming the 18th largest importer of electricity in the world. In the same year, Electricity was the 7th most imported product in Portugal. Portugal imports electricity primarily from Spain ($1.47B). In 2021, Portugal exported $561M in electricity, making it the 32nd largest exporter of electricity in the world. In the same year, electricity was the 26th most exported product in Portugal. The main destination of electricity exports from Portugal are Spain ($561M). At least we sell back almost 50% of what we import.
It is frequently claimed that EDP is owned by the Chinese. This is far from true. On February 4th, 2022, China Three Gorges (Europe), S.A. notified EDP that, in accordance with article 16 of the Portuguese Securities Code, it had reached a qualifying shareholding correspondent to 20.22% of EDP’s share capital and of the respective voting rights. The 20% threshold was crossed by China Three Gorges (Europe), S.A. on February 1st, 2022.
Why is electricity so expensive, blame the tax man
Unfortunately, Portugal has some of the highest prices for electricity in Europe thanks to taxes. According to Eurostat, we pay €0.2246 per kWh here which is 22% higher than in the UK. The “taxes and charges” component in Portugal is one of the highest in Europe and practically doubles the final price of electricity compared to the base value in Portugal according to EDP.
The other question frequently asked is why isn’t power from renewables cheaper? The simple answer to that is that the businesses that install and maintain them are not charities. They survive by making a profit, which seems reasonable. Also consider the capital investment needed to construct and install the units, be they solar, wind or even tide power. The old expression goes that there is no such thing as a free lunch. The sun wind and tides are free, but the equipment needed to harness what they produce isn’t. You may feel that the government should subsidise the equipment, but that would come from our taxes.
Whichever way you look at it, renewables are saving our planet, not our pockets.

Hi Paul, Tidal Power is not renewable -- in fact it can destroy the environment in less than 1000 years. Please see this extraordinary article that explains the science behind this statement: https://cs.stanford.edu/people/zjl/pdf/tide.pdf

I am not sure where your figures are coming from. If you can believe your electricity bill, my last one from SU (and the one before in brackets) and {my bill from the same period of 2020 in square brackets} says that my energy sources are ...
Eolica = 9.2% (7.8%) {25.5%}
Hidrica = 16% (14.5%) {23.3%}
Cogeneration renewable = 0.1% (0.1%) {3.2%}
Other renewable = 5.9% (4.8%) {9.8%}
Residuos solidos urbanos = 1.0% (1%) {0.8%}
Cogeneratao fossil = 3.9% (2.8%) {6.9%}
Gas Natural = 55.0% (61%) {24.8%}
Coal = 0.8% (0.9%) {5.7%}
Nuclear = 8.1% (7.1%) {0% - or undeclared!}
So I have both coal and nuclear electricity in my mix.
Comparing my 2023 bill with the 2020 figures, the proportion of wind energy I receive has decreased by 66%, hydro by 25% (maybe the rainfall pattern), and co-generation renewable is only 0.03% of what it was. Assuming that Other Renewables is solar then this has declined by 56%. Coal is now only 14% of what it was. However, gas use has increased by almost double and nuclear is now nearly 10% of our energy mix.

Another "renewable energy" rah-rah article--mixing mostly the writers opinions/hopes/wishes with few provable facts.
Here's a fact that the Liberal writer won't like - UBRELIABLE/expensive energy is more accurate than "renewable energy".
Wind and solar will NEVER be able to support modern economies without seriously lowering their standard of living!
Period!
Dream on "science / reality deniers"!!

Hi Simon. Regarding coal fired electricity, Portugal effectively phased out coal eight years ahead of schedule. You might find this interesting, https://www.energymonitor.ai/power/what-europe-can-learn-from-portugals-accelerated-coal-exit/

Hi Paul, I appreciate that Portugal may have phased out coal fired generation, and that it never had domestic nuclear powered generation. However, both of these still appear in my domestic energy mix. SU Electricidade has effectively outsourced their (or is it my?) environmental problems to France and Spain.
It is great to see a positive article about a positive response by Portugal to the Climate Crisis and it may be 100% accurate for the Portugal state generation system, but is not representative of where my electricity comes from.
My last bill showed that I was being supplied with 26.3% renewable energy, the one immediately before showed 32.7% was renewable and the one from 2020 showed 62.6%. My renewable electrical energy source is now 42% of what it was 3 years ago.
Maybe this could be the subject of a future article (or campaign) by you?

Interesting discussion. Your comments reflect the true nature of electricity production which fluctuates with supply, demand and pricing and can be pulled from various sources even outside the country. Statistics can vary significantly depending on if you are referring to electrical energy vs total energy, energy production vs consumption, so you have to compare apples to apples. It is true that wind doesn’t produce if it’s not windy and solar doesn’t produce if it’s not sunny and those sources vary significantly by season, so they are not considered baseline sources of energy - unless substantial improvement in storage is made available. However, conservation (as in retrofitting buildings etc) can reduce demand by 30%. Tidal, hydro, and geothermal sources can make up the baseline sources and are reliable year-round. I applaud Portugal for its sustainability goals and practices! Thank you for sharing.
