Sustainable Power Pt 2 - Solar Power
I’m sure by now everyone knows that solar power is energy harvested from the sun. In terms of sustainability, it is a fantastic power supply. You know you are going to have sun light until the sun burns out, which hopefully won’t happen anytime soon. Ever wondered how solar power works, here is a very brief synopsis.
Electricity is the flow of electrons from one place to another. We use conductors like copper and aluminum wire to get the electrons from the main utility distribution centers all the way down to your toaster. There are three (basic) important terms that coincide with electricity: Voltage, Amperage, and Wattage.
Voltage is the measure of electrical potential (electromotive force) of a circuit.
Amperage is the measure of the total amount of electricity that passes a given point at a given time.
Wattage is the measure of the amount of electrical power provided by the circuit.
Not to get too boring here, but if you have 2 of the values above you can always find the third.
Volt X Amp = Watt, Watt/Amp = Volt, Watt/Volt = Amp
Not much of segue here, but there are 2 types of current, DC, which is Direct Current and AC, which is Alternating Current. DC is a steady stream of electrons flowing from one point to another, it is the type of current that is used in vehicles and other electronic devices, it is the only type of current that can be stored in a battery. It always travels one direction. AC on the other hand goes from a positive peak to a negative trough and the back again (think sine wave) it reverses its direction many times a second, it is 60 times a second in the US. The measure of that reversing is called hertz. This is the power that comes from the utility company and is utilized in homes and businesses.
That’s probably enough for today, I will continue on next time. Thanks for reading!
