E9 G - Understand a current-topic explainer
Mini-Beschreibung: Du verstehst einen kurzen, altersgerechten englischen Explainer zu einem aktuellen Thema. Du arbeitest nach dem Weg English first → understand → respond → ask → hint → improve → use again. Beispielthema dieses Kurses: AI, data centres and electricity use. Zielgruppe: Klasse 9, Englisch als erste Fremdsprache, G-Niveau, Baden-Württemberg.
Wichtig: Du sollst nicht jedes Wort übersetzen. Verstehe zuerst die Hauptidee. Nutze Hilfen erst danach. Verständlichkeit ist wichtiger als ein perfekter Akzent.
Look first – no dictionary yet. What can you see? What may happen inside this place? Say two simple English sentences.
Media task: Watch the first part once without a transcript. Listen for only three ideas: AI – electricity – data centres. On the second viewing, you may use English subtitles. Do not translate the whole video.

Quick start – 2 minutes.
- Say three English words you connect with AI.
- Complete: A data centre is a place where ...
- Choose one: AI uses no electricity / some electricity / a lot of electricity. Explain why you think so.
- Write one question you have about AI and energy.
Do not check the answers yet. Your first idea is allowed to be incomplete.
Current-topic explainer: AI and electricity
Read in English first.
AI needs electricity. When you ask an AI tool a question, powerful computers in data centres do the work. These computers also need cooling. In 2025, data centres used about 485 terawatt-hours of electricity worldwide, according to the International Energy Agency. That was around 1.5% of global electricity demand. The IEA expects data-centre use to rise to about 950 terawatt-hours by 2030, or around 3% of global demand. AI is an important reason, but other digital services also use data centres. Efficiency is improving, yet more people are using AI and some tasks need much more energy than simple text. The future is not fixed: demand depends on technology, use, power grids and energy supply.
Stop and think:
- What is the text mainly about?
- Which two numbers describe the present and the possible future?
- Which sentence tells you that the future is uncertain?
- What does yet show: addition, contrast or reason?
Current fact check
The figures above use the International Energy Agency's current 2026 analysis. The IEA reports about 485 TWh of data-centre electricity use in 2025 and a central projection of about 950 TWh in 2030. A projection is not a guaranteed future result.
Reliable sources:
- IEA: Key Questions on Energy and AI – Executive Summary
- IEA: Artificial Intelligence and energy
- IEA: Energy and AI
Source rule: Check the date, the organisation and whether a number is a measured fact or a projection.
Listening and viewing
This IEA video from 2026 is longer. For G-level work, use only a short part first.
Round 1 – gist: Watch about 00:00–03:06. Do not open the transcript. Tick mentally: investment / data centres / electricity / school uniforms.
Round 2 – detail: Watch again. Pause after important ideas. Note only five key words.
Round 3 – support: Now use English subtitles or the YouTube transcript if needed. Compare with your notes. Do not make a full German translation.
Listening strategy: You do not need every word. Names, repeated words, images and numbers can help you.
Reading strategy
Use this four-step method:
- Headline: What topic do you expect?
- First read: Find the main message.
- Second read: Mark facts, reasons and contrasts.
- Check: Look up only words that block understanding.
Mini-check: In the explainer, underline mentally one fact, one projection and one contrast.
Context vocabulary
| Word | Simple English meaning | Small German help | Use it |
|---|---|---|---|
| data centre | a place with many computers and servers | Rechenzentrum | A data centre needs electricity. |
| server | a computer that stores or processes data | Server | The server does the computing. |
| electricity demand | how much electricity is needed | Strombedarf | Demand may rise. |
| cooling | keeping machines from getting too hot | Kühlung | Servers need cooling. |
| grid | the system that carries electricity | Stromnetz | The grid supplies power. |
| efficiency | doing the same job with less energy or fewer resources | Effizienz | Better efficiency can save energy. |
| projection | an evidence-based view of a possible future | Prognose | The 2030 figure is a projection. |
| source | where information comes from | Quelle | Check the source. |
| according to | as reported by | laut | According to the IEA, demand is rising. |
| yet | but at the same time | dennoch | Efficiency improves, yet total use can rise. |
No vocabulary dump: Learn the words through the topic and reuse them in sentences.
Media reading
Look closely: This roof shows cooling equipment and backup systems. Complete:
- I can see ...
- The equipment may be needed because ...
- One question I have is ...
Connect the image to the explainer: Use grid, electricity and data centre in one short explanation.
Compare: Solar and wind can produce electricity. A data centre can use electricity from different sources. Do not assume that every data centre has the same energy mix.
Pronunciation and fluency
Goal: clear speech, not accent-free speech.
Say these chunks slowly, then at normal speed:
- data centre
- electricity demand
- according to the IEA
- by twenty thirty
- The future is not fixed.
Chunking: Do not speak word by word.
According to the IEA / data-centre electricity use / may rise by 2030.
Fluency tip: Pause at meaning groups. Stress important content words such as data, electricity, rise and 2030.
Respond
Give a short reaction.
Frame A: I think this topic is important because ...
Frame B: One fact that surprised me was ...
Frame C: I am not sure about ... because ...
Keep your answer to two or three sentences first.
Ask
Useful follow-up questions:
- Why does AI need so much electricity?
- How can data centres use less energy?
- Where does the electricity come from?
- How certain is the 2030 projection?
- Which AI tasks need the most energy?
Now write one new question of your own.
Functional grammar
You need only a few useful structures.
| Function | Structure | Example |
|---|---|---|
| fact | present simple | Data centres use electricity. |
| reason | because | Cooling matters because servers get hot. |
| contrast | but / yet | Efficiency improves, yet demand can still rise. |
| cautious future | may / could | Demand may rise. |
| reported projection | expects ... to | The IEA expects demand to rise. |
Accuracy focus: Work mainly on because, but/yet and may/could. Communication comes first.
Speaking
30-second response:
Use this order:
- Topic: The explainer is about ...
- Key fact: One important fact is ...
- Reaction: I think ...
- Reason: ... because ...
- Question: I would like to know ...
Partner rule: Listen first. Then ask one real follow-up question.
Optional recording: You may record yourself privately for practice. Recording is voluntary. Do not upload it unless you have clearly chosen to do so and your school rules allow it.
Writing
Write 70–90 words.
Task: A class blog asks: Should we care about the electricity used by AI?
Use:
- a clear first sentence,
- one fact from the explainer,
- your opinion,
- one reason,
- one question for the reader.
Useful starters: The explainer shows that ... / According to the IEA ... / I think ... because ... / However ... / My question is ...
Keep your own text. Do not replace it with a completely new AI-generated version.
Mediation
Situation: A German classmate says: „Die Zahl für 2030 ist sicher, weil sie von einer Energieagentur kommt.“
Explain the idea in simple English to an exchange student.
Important: Do not translate every German word. Give the meaning.
Possible start: The 2030 number is not a fact yet. It is a projection, so ...
Hint ladder
Use only as much help as you need.
Hint 1 – key words: AI → data centres → servers → electricity → cooling → rising demand.
Hint 2 – sentence frames: The main idea is ... One important fact is ... The text says that ... may ... I think ... because ...
Hint 3 – mini-model: The explainer is about AI and electricity. Data centres need power for computers and cooling. The IEA expects electricity use to rise, but the future is not certain.
Now improve your own answer instead of copying the model.
Feedback and error analysis
Use message first, language second.
| Check | Ask yourself |
|---|---|
| Meaning | Can another person understand my main point? |
| Evidence | Did I use a fact correctly and call a projection a projection? |
| Reason | Did I use because for a real reason? |
| Contrast | Did I use but or yet clearly? |
| Future language | Did I use may, could or expects to when the future is uncertain? |
Three useful corrections:
Not good: Data centres will use exactly 950 TWh in 2030. Better: The IEA expects data centres to use about 950 TWh in 2030.
Not good: AI need electricity. Better: AI needs electricity.
Not good: I think it is important because electricity. Better: I think it is important because data centres need a lot of electricity.
Use again: Transfer
Choose a new current topic, for example heatwaves, microplastics, electric cars, AI-generated media or urban wildlife.
Find one short English explainer from a reliable source. Then repeat the same route:
English first → understand → respond → ask → hint → improve → use again.
Before using a number, check:
- Who published it?
- When was it published?
- Is it a measured fact, an estimate or a projection?
- Can another reliable source support it?
Do not use private social-media profiles or personal data for class research.
Safe and responsible use of AI
AI tools are optional. This course works without external AI access.
If you use AI:
- Check factual claims with reliable sources.
- Keep your own original text and compare changes.
- Do not upload private recordings, names, addresses, application data or private social-media information.
- Treat AI feedback as a suggestion, not as a fact.
- If a source is unclear, go back to the original source.
Fictional profiles and fictional personal details should be used for practice tasks.
