SDG 7 · Affordable and Clean Energy

655 million people still live without electricity.

Eco Heroes turns that fact into a story a 9-year-old can hold onto: A Furrowed Brow, book 7 of 17 in the SDG Library.

The target, in plain language

What the UN actually promised

Target 7.1

By 2030, ensure universal access to affordable, reliable and modern energy services.

Modern energy means reliable electricity and clean cooking, not firewood, charcoal or kerosene smoke inside the home.

Target 7.2 asks the world to substantially increase the share of renewable energy in the global energy mix.

Why it matters

The number behind the story

655M
people were living without electricity in 2024 On current trends, around 1.8 billion people will still rely on polluting fuels and technologies to cook in 2030.

Bring it into the room

Talk about it, try it

Discuss

One question to ask after reading

“What would you miss first in a home with no electricity after dark? And what would you do instead?”

Try it: 15 minutes

Run a power audit

Walk around your home or classroom and list everything that's plugged in. Sort it into “need”, “nice to have” and “could switch off right now”, then switch one thing off together.

Watch

The short mission video

April and Karim walk through this goal in a short video, with subtitles in your language.

Everything said in the video, in order, with the words and figures shown on screen.

Version for ages 9–12

  1. April: Power the world, without wrecking it. An Eco Heroes mission.
  2. On screen: An Eco Heroes mission · Goal 7 · ages 9–12
  3. On screen: See something real
  4. April: Devices on standby quietly sip power all day. Where does the electricity in this room come from?
  5. On screen: A real question is where every mission starts.
  6. On screen: Investigate the system
  7. Karim: Clean Energy is a system, not a headline.
  8. On screen: 685M people live with no access to electricity. (Source: IEA / World Bank, 2022)
  9. On screen: 2.3B people cook with polluting fuels that harm their health. (Source: WHO, 2023)
  10. On screen: #1 Solar and wind are now the cheapest source of new electricity in most countries. (Source: IEA, 2023)
  11. On screen: Step 4 · Meet someone who understands it
  12. Karim: 685 million people live with no access to electricity. 2.3 billion people cook with polluting fuels that harm their health. Ask the people who know: an electrician, someone with solar panels, your building's caretaker.
  13. April: Your mission — The Energy Hunter. Track down energy being wasted in your home. Do: Find 5 things left on or plugged in when not used.
  14. On screen: Prove: Switch them off and note which ones.
  15. On screen: Reflect: Which was easiest to change for good?
  16. April: Bring it to school.
  17. On screen: Bring it to school: Show your class what you found. One finding from each of you becomes a map of your town.
  18. April: Show your class what you found. Discuss it at home.
  19. On screen: Discuss it at home: Tell your family what you did and ask them one question about it. Information fades — questions travel.
  20. April: Tell your family what you did and ask them one question about it. Take action locally.
  21. On screen: Take action locally: Pick the one action from your mission you can do this week — and tell one person why.
  22. Karim: A true story — The Boy Who Harnessed the Wind. I try, and I made it.
  23. On screen: Small hands. Real problem. Real change.

Version for ages 13–17

  1. April: Clean power is cheaper.
  2. On screen: An Eco Heroes mission · Goal 7 · ages 13–17
  3. On screen: Notice something real
  4. April: So what's the hold-up? 91% of new renewable power projects are now cheaper than new fossil fuel options. If clean energy is cheaper, why do we still burn so much coal, oil and gas?
  5. On screen: Hard questions are where real missions start.
  6. On screen: Map the system
  7. Karim: Energy is a system: grids, money, jobs, habits and politics. 655 million people still live without electricity, almost 9 in 10 of them in Africa.

  11. On screen: Step 4 · Talk to someone who knows
  12. Karim: Interview someone who knows: an electrician, an energy engineer, someone from a local energy co-op.
  13. April: Your mission — Energy Audit. Find where your school wastes energy — and what it costs.
  14. On screen: Do: Read the meters or bills and log what stays on after hours.
  15. On screen: Prove: Calculate the yearly cost of the waste.
  16. On screen: Reflect: Would solar panels pay off here — and who decides?
  17. April: Take it to school.
  18. On screen: Take it home: Find your home's biggest energy user and compare tariffs with your family.
  19. On screen: Act where you live: Ask your council about local solar or join an energy co-op campaign.
  20. On screen: Real data. Real questions. Real change.
  21. April: Present your audit to the student council with one costed fix. Then take it home, and act where you live.
  22. Karim: A true story. I try, and I made it. William Kamkwamba. 17 goals, 13 languages, your move. eco-heroes.org
A real example

Solar power reaches rural Kenya

In Kenya, off-grid solar has reached 2.3 million homes with no grid connection. Companies like M-KOPA allow payments by mobile phone — making solar affordable for the first time for rural families.

  1. Coal
  2. Oil
  3. Solar

Answer: Solar — Solar energy is renewable — it comes from an inexhaustible source (the sun) and produces no emissions when generating power.

Fossil fuels currently provide about 80% of the world's energy.Show the answer

Answer: True — Despite rapid growth in renewables, fossil fuels still supply around 80% of global energy.

What is energy poverty?Show the answer
  1. Expensive energy bills
  2. Lack of access to modern, reliable energy services
  3. Using too much energy
  4. A type of renewable

Answer: Lack of access to modern, reliable energy services — Energy poverty affects 800 million people who have no access to electricity and 2.6 billion who cook with polluting fuels.
