What is energy poverty?

While most of us take electricity for granted in 2017, over 1 billion people still live without access to clean and affordable energy accross the globe.

Energy poverty strongly impacts:

  • Education: children cannot study after dark, often around 7pm in the Southern hemisphere
  • Safety: off-grid communities rely on toxic and hazardous kerosone lamps to illuminate their homes
  • Revenues: men and women have to stop their daily activities which means less revenues for the household

Off-grid communities are not HEYJOOL’s core market, but are our core motive in designing the JOOL product line. We aim at creating awareness around this global issue and distribute our products to those in need at the lowest price possible.
