There's an energy revolution happening in villages and towns across Africa -- off-grid solar energy is becoming a viable alternative to traditional electricity systems. In a bold talk about a true leapfrog moment, Amar Inamdar introduces us to proud owners of off-grid solar kits -- and explains how this technology has the opportunity to meet two extraordinary goals: energy access for all and a low-carbon future. "Every household a proud producer as well as consumer of energy," Inamdar says. "That's the democracy of energy."

Renewables require change in the energy supply chain. Subscribe to our channel! http://goo.gl/0bsAjO Electricity is incredibly difficult to store, so grid operators have to generate it at the exact moment it is demanded. In order to do this, they create incredibly accurate models of the total electric loads, that is how much energy will be consumed on a given day. But as utilities started to produce more energy from renewable sources like solar, the models started to shift as well. California researchers discovered a peculiarity in their state’s electric load curves, that started to look more and more like a duck. And that duck shaped chart highlights the greatest challenge to solar energy growth in the US. Vox writer David Roberts has been covering the issue for a few years now. You can read some of his past explainers on the duck curve, and its solutions at the links below: https://www.vox.com/energy-and-environment/2018/3/20/17128478/solar-duck-curve-nrel-researcher https://www.vox.com/2016/2/10/10960848/solar-energy-duck-curve https://www.vox.com/2016/4/8/11376196/california-grid-expansion https://www.vox.com/2016/2/12/10970858/flattening-duck-curve-renewable-energy And if you would like to read some of the source material used in the video above, you can check those out here: https://www.caiso.com/documents/flexibleresourceshelprenewables_fastfacts.pdf https://www.nrel.gov/docs/fy16osti/65023.pdf Vox.com is a news website that helps you cut through the noise and understand what's really driving the events in the headlines.

The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides explains how solar towers and panels create electricity and how scientists are trying to create a system that can function even under cloud cover.

View full lesson: https://ed.ted.com/lessons/how-do-solar-panels-work-richard-komp The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. Lesson by Richard Komp, animation by Globizco.
