        "content": "Here\u2019s a detailed overview of how household energy is consumed in the EU, especially which appliances or activities are **most economical** vs **least economical**, based on the latest data (2023\u20132025). The shares show typical energy breakdown in households; then I rank specific appliances by relative efficiency and energy demand, plus give examples of best vs worst per appliance type.\n\n---\n\n## 1. Big Picture: Where Household Energy Goes\n\nAccording to Eurostat, in 2023 in EU households:\n\n- Space heating (warming homes) takes up **62.5%** of household energy.  \n- Water heating: ~15.1%  \n- Lighting and electrical appliances: ~14.5% (this excludes electricity used for heating, cooling, or cooking)  \n- Cooking: ~6.5%  \n- Space cooling & \u201cother end-uses\u201d: together under 1.5% ([ec.europa.eu](https://ec.europa.eu/eurostat/statistics-explained/SEPDF/cache/58200.pdf?utm_source=openai))\n\nSo the **least economical** really tends to be heating (space + water), because those dominate the energy usage. Appliances & lighting are smaller overall but still important.\n\n---\n\n## 2. Which Appliances Use the Most Energy (Least Efficient / Greatest Demand)\n\nHere are common appliances (or appliance groups) that **drive up energy consumption**, plus how the EU is improving and where the gaps remain:\n\n| Appliance / Activity | Why Energy Use Is High | Typical Use / Annual Energy (if known) |\n|---|---|---|\n| **Space heating** | Runs many hours daily during colder months; often powered by natural gas or electricity with losses. | ~60-65% of household energy used just for heating ([ec.europa.eu](https://ec.europa.eu/eurostat/statistics-explained/SEPDF/cache/58200.pdf?utm_source=openai)) |\n| **Water heating** | Needs constant heating, even when not in active use; stored water loses heat over time. | ~15% of household energy ([ec.europa.eu](https://ec.europa.eu/eurostat/statistics-explained/SEPDF/cache/58200.pdf?utm_source=openai)) |\n| **Tumble dryers** / **washer-dryers** | Especially inefficient; dryers use a lot of power, and washer-dryers combine two high-use functions. EU aims to halve energy use for tumble dryers via new regulations. ([energy.ec.europa.eu](https://energy.ec.europa.eu/news/5-things-you-should-know-about-energy-efficient-products-2025-12-17_en?prefLang=sk&utm_source=openai)) |\n| **Refrigerators & freezers** | Run 24/7, must maintain temperature; older models are much less efficient. |\n| **Washing machines** | High energy per cycle; hot water washing especially costly. But regulations have cut electricity consumption significantly. Average EU washing machine went from ~350 kWh/year in 1990 to ~96 kWh/year in 2020. ([energy-efficient-products.ec.europa.eu](https://energy-efficient-products.ec.europa.eu/product-list/washing-machines_en?prefLang=de&utm_source=openai)) |\n| **Dishwashers** | Heating water + drying functions consume both electricity & water; modern \u201ceco\u201d modes help but usage patterns matter. |\n| **Cooking appliances, ovens** | Intermittent but can be energy-intensive, especially if baking or roasting for long times, or using non-induction surfaces. |\n\n---\n\n## 3. Most Economical Appliances & Efficiency Gains\n\nSome appliance categories have seen dramatic improvements due to new EU rules:\n\n- **Washing machines**: As of 2020, thanks to energy label & ecodesign rules, electricity per year dropped from ~350 kWh/year (1990) to ~96 kWh/year, anticipating ~93 kWh/year by 2030. ([energy-efficient-products.ec.europa.eu](https://energy-efficient-products.ec.europa.eu/product-list/washing-machines_en?prefLang=de&utm_source=openai))  \n- **Tumble dryers**: New tech like heat pumps can cut energy use roughly in half vs conventional drying. ([energy.ec.europa.eu](https://energy.ec.europa.eu/news/5-things-you-should-know-about-energy-efficient-products-2025-12-17_en?prefLang=sk&utm_source=openai))  \n- **Lighting**: LEDs replaced incandescent bulbs; energy required for lighting per household reduced. ([energy.ec.europa.eu](https://energy.ec.europa.eu/news/5-things-you-should-know-about-energy-efficient-products-2025-12-17_en?prefLang=sk&utm_source=openai))  \n\n---\n\n## 4. Ranking: Most Economical \u2192 Least Economical (Generalized)\n\nHere\u2019s a rough ranking of appliance / system types from **most efficient** (for the energy provided) to **least**, assuming you pick modern, efficient models and use them reasonably:\n\n1. LED lighting and efficient small electronics (phone chargers, laptops with power-saving features)  \n2. Modern efficient washing machines (especially cold wash, full load)  \n3. Efficient refrigerators/freezers (Properly sized, well-sealed)  \n4. Dishwashers with eco modes + efficient drying  \n5. Cooking appliances: induction hobs / ovens with good insulation  \n6. Air conditioning (if used occasionally and with heat pump tech)  \n7. Tumble dryers / washer-dryers (especially non-heat pump types)  \n8. Water heating (if using older systems / lower insulation)  \n9. Space heating (especially in older, poorly insulated homes)\n\nBecause space heating dominates, investing in improved insulation or heat pump systems tends to give bigger energy reductions than switching from one fridge model to another.\n\n---\n\n## 5. Examples: Best vs Worst Scenarios (by Appliance)\n\nHere are some concrete numbers showing **most economical vs least** in common appliance categories:\n\n- **Washing machines**  \n  * *Worst case (old, low-efficiency)*: ~350 kWh/year without regulation (1990 average). ([energy-efficient-products.ec.europa.eu](https://energy-efficient-products.ec.europa.eu/product-list/washing-machines_en?prefLang=de&utm_source=openai))  \n  * *Best case now*: ~90\u2013100 kWh/year with modern efficient models (ECE regulation) ([energy-efficient-products.ec.europa.eu](https://energy-efficient-products.ec.europa.eu/product-list/washing-machines_en?prefLang=de&utm_source=openai))  \n\n- **Washer-dryers** (combined washing + drying): generally worst energy users among laundry appliances. Example: a 6-kg washer-dryer combo could use ~3.6 kWh/cycle, giving ~800 kWh/year under heavy usage. ([eur-lex.europa.eu](https://eur-lex.europa.eu/legal-content/EN/TXT/?toc=OJ%3AL%3A2019%3A315%3ATOC&uri=uriserv%3AOJ.L_.2019.315.01.0285.01.ENG&utm_source=openai))  \n\n- **Tumble dryer heat-pump types vs conventional**: Heat pump models use about **half** the energy of older vented models. ([energy.ec.europa.eu](https://energy.ec.europa.eu/news/5-things-you-should-know-about-energy-efficient-products-2025-12-17_en?prefLang=sk&utm_source=openai))  \n\n---\n\n## 6. Policy & Labels: How the EU Plays a Role\n\n- EU uses **energy labels** (A to G) for many appliance types; newer labels re-calibrated so fewer very high letters; older +/++/+++ system phased out. ([europa.eu](https://europa.eu/youreurope/citizens/consumers/shopping/energy-labels/indexamp_en.htm?utm_source=openai))  \n- **Ecodesign standards** force minimum performance, removing the worst appliances from market. These rules have led to significant energy savings and lower operating costs. ([iea.org](https://www.iea.org/reports/energy-efficiency-policy-toolkit/appliances?utm_source=openai))  \n- Consumers save ~\u20ac320/year on average thanks to these standards, around an 8% reduction in energy bills in 2024. ([energy.ec.europa.eu](https://energy.ec.europa.eu/news/5-things-you-should-know-about-energy-efficient-products-2025-12-17_en?prefLang=sk&utm_source=openai))  \n\n---\n\n## 7. What Makes a Difference: Behavior and Usage\n\nEfficiency of appliances depends heavily on usage patterns:\n\n- Using full loads for washers/dishwashers  \n- Washing clothes at lower temperatures  \n- Reducing dryer use by air-drying when possible  \n- Keeping refrigeration units properly filled and maintaining correct temperature settings  \n- Turning off standby modes; unplugging small devices when not in use  \n\n---\n\nIf you want, I can pull together a more specific table of current yearly costs for popular models (efficient vs inefficient) for EU-wide average electricity tariffs. Do you want me to build that?"
