Ask any climate scientist how we should power our world without fossil fuels, and they’re bound to tell you about wind and solar power.
You might be surprised to know that both of these come from the sun. Solar panels collect the sun’s energy directly, but we wouldn’t even have wind if not for the sun.
Why? Because in order to move, you need energy. And not just you. I’m talking about every speck of material on Planet Earth that shifts an inch. It’s because it has energy.
That energy can come from a lot of places. Earth is still a dynamic world with a hot interior, but it’s not hot enough to sustain all the life and other movement on its surface. A lot of our planet’s energy comes from the sun.
But here’s the big question. How the heck does it get here? Continue reading
Take a wild guess: how much energy do you think the sun generates?
Think about it. It definitely generates enough energy to power a world.
Humans depend on the photosynthesis of plants, which converts sunlight into energy. And that’s not all. Without energy from the sun, our atmosphere would behave very differently, and so would our oceans.
Everything that moves on Planet Earth does so because it has energy. And a lot of that energy comes from the sun. It doesn’t even stop there—obviously, the sun has plenty of energy to spare, if the recent influx of solar power means anything.
The sun is incredibly powerful. And it’s powerful enough to keep generating that kind of massive energy supply for billions of years.
So where does it get all its energy? Continue reading
Does this image look familiar?
It should—these are soap bubbles.
Okay, now you’re probably going to ask me how soap bubbles have anything to do with the battery of the sun.
Well…you might be surprised to know that soap bubbles actually work as models of stars.
How? Continue reading
