The Sun is the only reason life on Earth is possible. It provides us with light, warmth, and the energy we need to power our world. We are only just beginning to understand how to capture that energy and put it to use. Solar panels are becoming more popular, but as of 2021, even the most advanced could only capture about 22% of the solar energy we are exposed to. Even if their efficiency stayed the same, scientists calculated that the world’s current electricity needs could be met by solar energy alone. It would require just 3.27% of the US to be covered with solar panels. Considering how much power these panels generate with just 22%, imagine what we could do with 50% or more!
