Electricity Generation 101 Part 2

Here’s a little recap from an earlier post: Energy is generated from a renewable or non-renewable source mined, harvested or collected from the earth. For every energy source, a chemical or mechanical process is required to turn it into electrical energy. The energy source then heats up water in the turbines, which makes the propellers spin and create mechanical energy. It is the generator inside these turbines that converts the mechanical energy into electrical energy or electricity. Transporting electricity to your home is an entirely different process and we will elaborate on this topic today.

Current technology cannot store large amount of electricity, and as a result significant challenges occur transporting energy across long distances. Just enough energy has to be generated to meet the current demand and to be transmitted across the power lines to your home and to your switches. Too much or too little power can crash the transmission system and create a blackout. A proper combination of logistics, management and infrastructure is required to make sure there is a smooth process of electricity generation from power generators and safe delivery to the consumer.

If you have ever driven across the U.S. or even across some state boundaries you may have spotted some electricity grids. The U.S. is divided into four large grid systems—the Eastern Grid, The Western Grid, the Texas Grid and a Grid covering the Canadian Province Quebec. You may be surprised to learn that Texas accounts for 10 percent of the nation’s energy usage, and has its own grid to produce and consume that energy.

The independent regional networks of power plants and transmission lines carry electric energy at high voltage to local utilities. From there, electricity first enters your local power substation where the voltage is reduced through transformers. There are more transformers on the power lines on your street near your home that also reduce the high voltage to 110 volts, which you use in your home. From the power lines the electricity enters your home’s breaker box from where it is distributed to the light sockets and switches. Now, if you flip a light switch, a bulb lights up.
