The time it takes to repay the cost of installing rooftop solar has dropped dramatically as energy costs have spiked, with new data suggesting it could soon take just four years to pay off a new system through savings on…

California is the best state for solar power because of how much direct sunlight the solar panels have access to. Since the sunlight is beaming down practically all summer in California, solar panels can potentially convert a lot of energy…

The news: Researchers at Stanford University have invented a breakthrough solar panel that can generate electricity in dark. It’s based on radiative cooling, in which Earth’s surface rapidly loses heat after the sun sets—a phenomenon that could be game-changing for…

As a renewable source of power, solar energy has an important role in reducing greenhouse gas emissions and mitigating climate change, which is critical to protecting humans, wildlife, and ecosystems. Solar energy can also improve air quality and reduce water…

What is climate change? Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of…

Green energy is any energy type that is generated from natural resources, such as sunlight, wind, or water. It often comes from renewable energy sources although there are some differences between renewable and green energy, which we will explore, below.…
