You flip on the morning news or get a dreaded weather alert on your cell phone. A bad storm is coming this evening starting at 6 pm. You're off to work but remember that you are long overdue for a trip to the grocery store. We know the fine people on the morning news tend to exaggerate these storms, but just in case you figure you better head to the store to stock up after work. You do have your mother-in-law with you, and with her health problems you can't take the chance of being without food or water for several days.
Most days we take the electricity in our home for granted. We flip a switch and expect a light to come on. We open the door to the refrigerator and expect the milk to be cold, we expect the AC to work in the summer and the heat to work in the winter. It's hard to imagine back to a time before people had electric in their homes. The electricity that surrounds us has become so much a part of our daily lives that we don't notice it exists.
