6. If you only learn one thing
It’s easy to get started, even
without any devices

7. Number of devices

29. Wind generation progress
 At just before 2am on Saturday 8 February, wind
turbines generated 56% of the country’s electricity.
This was nearly 15GW of power, according to Drax
Electric Insights.
 Wind power generates 140% of Denmark's electricity
demand

31. Problems with renewable energy
 Enough rain to power hydro generators
 Wind for wind turbines
 Clear sky and sunshine for solar panels
