La energía solar

The video discusses the vast potential of solar energy, which can provide more energy in one hour than the world consumes in a year. It explains the photovoltaic method, where sunlight releases electrons in materials like silicone, generating electricity. Initially used in small devices, photovoltaic cells now power satellites, with production growing rapidly. However, solar power plants are costly and inefficient due to sunlight unpredictability and storage issues. Solar heating panels offer an alternative by heating water for buildings. The video highlights the need for improved solar energy capture and storage technologies to make it a dominant energy source.
