Meeting 100% of a home's power needs with solar energy is doable. But there are a few factors to consider. First, you'll need to determine how much energy you use, and then assess certain limiting factors for your property. These factors include the space you have available for your solar system.

"The Earth receives 23000 TW of solar energy, while the global energy consumption is 16 TW. Therefore, [100 percent renewable energy] could be possible even if we capture only 0.07 percent of the solar energy" says Professor Xiao Yu Wu, an energy expert from MIT.

Even in the most ambitious scenarios, the world has enough materials to power the grid globally with renewables, the researchers found. And mining and processing those materials won't produce enough emissions to warm the world past international targets. There is a catch to all this good news.

One of the great advantages perovskites offer is their great tolerance of defects in the structure, he says. Unlike silicon, which requires extremely high purity to function well in electronic devices, perovskites can function well even with numerous imperfections and impurities.

The good news is that most residential solar panels should operate for 25 years before degradation (or reduced energy production) is noticeable. Even after that point, solar panels can continue to convert sunlight into solar energy—just at a less efficient rate than when they were new.
