The Answer to the Question: Does a Source of Electricity Ever Run Out of Electrons?
There are plenty of sources of electricity, from solar panels to turbines in waterfalls and even the wind. The question we want to answer today, however, is does a source of electricity ever run out of electrons? The answer to this question may surprise you; there is no such thing as running out of electrons! Let’s dive deeper into what we mean by that, but first here are some facts about electricity that you should know. [...]
A quick primer on how electrons flow
A gas is something that is in constant motion. Gases are made up of molecules, and molecules are made up of atoms. These atoms have one or more electrons orbiting around them, and these orbitals are constantly spinning. The electron has a negative charge, so it repels other electrons from it's orbital. This causes electrons to change their orbits and move around, creating an electric current (or flow) which we call electricity.
Where do these free electrons come from?
These free electrons come from the gas, which is an unstable molecule. When they break apart, they release these electrons. This process is called ionization. The gas turns into an ionized gas when it has lost all its electrons and becomes positively charged. This type of electron is called a free electron.
So are we running out, or what?
There are no more electrons in the universe than there are stars. And since the universe is expanding, there are more stars all the time. So it's not possible for any source of electricity ever running out of electrons.
How will we deal with it if we do start running out of free electrons in the future?
If we do start running out of free electrons in the future, it would make sense for us to start looking into alternative sources. One potential solution is solar power. The Sun produces more energy than any other natural source, and we could use this free energy supply to power our homes. Solar panels are becoming more affordable every day and they're also getting better at converting sunlight into electricity.
And how should this affect how you live your life right now?
No, it is impossible for a source of electricity to run out electrons. This question stems from not understanding that there are different types of electrons. The electrons in a battery do eventually run out and need to be recharged. However, they're called secondary electrons because they can be regenerated when it's time for them to be used again.
