The sun has powered organic life on planet Earth since before human beings even existed. And we’ve attempted to harness the power of solar energy since the very beginning. Although early uses for solar energy revolved around methods to ignite a fire, the 20th century introduced mankind to the potential of solar electricity. In this… Continue reading Renewable Energy 101: How Does Solar Energy Work?
View full lesson: Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven’t we made the switch? 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… Continue reading Why aren't we only using solar power? – Alexandros George Charalambides

The sun. One of the most powerful energy sources ever available to humans. The process of exploration this energy began more than two thousand years ago, requiring at first colossal knowledge and skills from a person. Thanks to this labor, today, solar energy has become the cheapest in history. But why, with all its cheapness,… Continue reading How solar energy became the cheapest in history
More and more countries of the world are beginning to use alternative energy sources, including solar. Therefore, modest rooftop panels are being replaced by “solar farms” spread over vast areas. So, the fourth-largest solar power plant in the world, Benban Solar Park is located in Egypt, covers an area of 37 square kilometers, and generates… Continue reading How the world's largest solar power plant works
View full lesson: 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,… Continue reading How do solar panels work? – Richard Komp
