VOICED: Tejados para ahorrar energia

The video discusses the benefits of painting roofs white to combat climate change. White roofs reflect sunlight, reducing building temperatures and energy costs. In San Francisco, a law mandates white roofs on new commercial buildings, significantly impacting energy consumption. Arthur Rosenfeld, a leading energy researcher, advocates for global adoption, highlighting the potential to reduce greenhouse gas emissions. While not a complete solution to climate change, white roofs offer an easy, cost-effective way to manage energy use. The video concludes with a call to action for worldwide implementation.
