Renewable Energy Engineering is the study and application of technologies that generate power from natural resources that are constantly replenished — such as the sun, wind, water, and biomass. Unlike fossil fuels, these sources are renewable and more environmentally friendly. In Joluo communities, renewable energy can play a central role in promoting sustainable development while respecting cultural values and the natural environment.

Gravity(teko mar kelo piny) is one of the most important forces in the universe(achiel kuom teko madongo e piny mangima). It is the invisible pull(ywecho ma ok nen) that keeps us standing on the ground(mamiyo wachung e loo), holds the air we breathe close to the Earth(mako yamo ma wayweyo but piny), and guides the stars(chiko sulwe) and planets in the sky. However, what exactly is gravity, and how can we explain it in the Joluo context?

In Joluo communities, the sun— Chieng'—has long shaped daily rhythms, farming practices, and traditional timekeeping. Today, harnessing this abundant natural resource through solar energy (Teko mar chieng') offers an exciting opportunity to sustainably improve livelihoods, education, healthcare, and economic growth. This post introduces the concept, benefits, and practical applications of solar energy tailored to Joluo communities.
