Shaping the energy future: 100% green
Europe faces a significant challenge: meeting the rising demand for energy while simultaneously tackling climate change. To address this, more and more countries are turning to renewable energy sources and efficiency measures – a transformation that is already clearly visible across many sectors.
In 2023, 45.3% of electricity in the EU came from renewable sources such as hydropower, wind, and solar energy. The share of sustainable energy used for heating and cooling is also steadily increasing, reaching 26.2% in the same year.
By 2030, the EU has set ambitious goals: to reduce greenhouse gas emissions by at least 55% and to further accelerate the growth of renewable energy.
Italy is performing well compared to the European average: by 2023, 39% of the country’s electricity was generated from renewable sources, primarily solar, hydro, and geothermal systems. However, certain sectors face particular challenges in improving energy efficiency – especially industry, transportation, and tourism.
Hotels and resorts, for example, have high energy demands for hot water, heated pools, air conditioning, and lighting. At the same time, this sector also offers significant opportunities to reduce consumption through innovative technologies and targeted measures, paving the way for a more sustainable future.
100% Green Energy – Our biggest step forward
Since 2024, all ADLER Spa Resorts and Lodges have been meeting their entire electricity needs with 100% green energy. This milestone was made possible through our partnership with Alperia, one of South Tyrol’s leading providers of renewable energy. Today, every one of our properties is powered exclusively by sustainable sources, including hydropower and photovoltaic energy.
In 2024, the total electricity consumption of our group reached 8,043,591 kWh. To put this into perspective, the average Italian household uses around 3,000 kWh per year – meaning our group’s consumption is comparable to the annual energy use of a small town of roughly 2,700 households.
Had this energy been drawn from the standard Italian electricity mix, it would have resulted in approximately 2,735 tons of CO₂ emissions.
By switching entirely to green energy, we prevent these emissions, which is equivalent to:
This step marks a major milestone on our journey toward climate-friendly hospitality and demonstrates the tangible impact that sustainable decisions can make.
Energy from the sun – photovoltaic projects in our Resorts
In addition to sourcing green energy, we are investing in producing our own electricity from renewable sources.
In Tuscany, our photovoltaic system already covers 30% of the resort’s total energy consumption.
On the Plose, the system supplies around 25% of the electricity required by the AKI Family Resort.
Starting in 2026, a large photovoltaic installation will also become operational at the ADLER Spa Resort Sicilia, where it will provide approximately one-quarter of the property’s energy needs.
All the electricity generated is used directly on-site, ensuring that our resorts are supplied with clean, renewable energy while reducing reliance on external providers – an important step towards climate protection and greater energy independence.
More Efficiency, Less Consumption – Our Energy Management
Energy efficiency starts with the very design and architecture of our resorts.
An optimized building structure, featuring high-quality thermal insulation, modern windows, and well-insulated roofs, minimizes heat loss in winter and keeps rooms pleasantly cool in summer – significantly reducing the need for heating and cooling.
Carefully planned architectural elements, such as shaded facades and large windows that maximize the use of natural daylight, further lower energy consumption. Where possible, we also incorporate green roofs, which provide extra insulation, enhance the surrounding microclimate, and create natural habitats for plants and insects.
When selecting construction materials, we focus on regionality and durability, choosing locally sourced wood and natural stone that combine aesthetics with a low environmental footprint.
For lighting, all ADLER properties have been fully converted to LED technology. Light sensors and automated systems ensure illumination is only active when truly needed, adjusting to natural daylight and occupancy levels.
Another area with significant energy-saving potential is our pools: Pool covers, now standard across all our resorts, prevent heat loss overnight and greatly reduce the energy required to maintain optimal water temperatures.
Finally, every ADLER Resort is equipped with charging stations for electric vehicles, powered by 100% green energy. This allows our guests to travel emission-free and recharge their vehicles sustainably during their stay – an important step toward creating a fully sustainable holiday experience.
Smart systems and heat generation
In addition to architectural solutions, we use smart management systems that regulate heating, cooling, ventilation, and other facilities based on occupancy, time of day, and weather conditions. Energy-intensive equipment such as refrigeration and freezing systems, dishwashers, saunas, whirlpools, and laundry machines are continuously monitored to identify potential savings and optimization opportunities.
A key element of our approach is natural climate control. Rather than relying on conventional air conditioning systems, we use advanced technology that adjusts room temperatures gently and efficiently. Guests can fine-tune their room temperature by ±3 °C, ensuring a comfortable environment while keeping energy consumption to a minimum.
For heat generation, we rely on a diverse mix of sustainable technologies, including pellet heating systems, district heating, heat pumps, geothermal energy, and combined heat and power plants (CHP). In addition, heat recovery systems are used to reclaim energy from exhaust air, wastewater, and cooling processes, ensuring that no energy goes to waste.
A standout example of innovation is the ADLER Spa Resort Sicilia, the only property in our group powered entirely by green electricity, with no gas supply – a decisive step toward CO₂-neutral energy management and a model for the future of sustainable hospitality.

How each of us can save energy
Energy efficiency is a collective effort, and everyone has the power to make a difference.
Even small changes in daily habits can have a meaningful impact, helping to save energy, cut costs, and protect the environment:
Even while staying at our resorts, guests can actively contribute to energy savings – all without compromising comfort.
Here are a few simple but effective steps:
Through the consistent use of green energy, our photovoltaic systems, and a wide range of efficiency measures, we have significantly reduced energy consumption while preventing substantial CO₂ emissions.
In doing so, we make a tangible contribution to climate protection, lower our operating costs, and preserve valuable natural resources – proving that modern tourism can thrive in harmony with responsible resource management.
Energy efficiency is a collective effort, and everyone has the power to make a difference.
Even small changes in daily habits can have a meaningful impact, helping to save energy, cut costs, and protect the environment:
- Heat consciously: lowering your room temperature by just 1 °C can save around 6% of energy.
- Switch to LED bulbs: they use up to 80% less energy than traditional light bulbs.
- Turn devices off completely: avoid stand-by mode to prevent silent energy waste.
- Save hot water: take shorter showers and use efficient faucets to reduce both water and energy use.
- Run appliances fully loaded: washing machines and dishwashers work more efficiently when fully loaded, saving water, energy, and detergent.
Even while staying at our resorts, guests can actively contribute to energy savings – all without compromising comfort.
Here are a few simple but effective steps:
- Remove the room card: when the card is taken out, air conditioning, heating, and lighting automatically switch to a minimal level, preventing unnecessary energy use while the room is unoccupied.
- Reuse towels: this helps significantly reduce water and energy consumption in our laundry operations.
- Keep windows closed: when heating or air conditioning is on, to prevent energy loss and maintain indoor comfort efficiently.
- Travel sustainably: choose public transportation or an e-car for arrival and departure – and rely on eco-friendly mobility on site, such as e-bikes, bus, train, or simply walking.
Through the consistent use of green energy, our photovoltaic systems, and a wide range of efficiency measures, we have significantly reduced energy consumption while preventing substantial CO₂ emissions.
