we all depend on electricity. most electricity is created by electromagnetic generators at large power plants and distributed through an electric grid. the electric grid in the united states is interconnected and includes more than 400,000 miles of electric transmission lines. however, the grid has not been well maintained, and the number and severity of power outages have been rising over the past decade. because the grid is interconnected, a severe power outage in one area can quickly spread to other areas.
how long could you survive without electricity?
what parts of your life would be affected by the loss of electricity? should you prepare for an electricity outage, and if so, how would you prepare? what backup system could your family or community install to generate limited amounts of electricity during an outage? how does this system creates an electric force field and generate electric current?

If there was a power outage, you could survive normally using older ways of life and with proper preparations; some ways to prepare is having canned foods that don't require heating or refrigeration, since you wouldn't have electronic means of preparing it, and supplies for starting camp fires. Some ways your life would be affected is lack of simple methods of day-to-day tasks that you have become accustomed to: no warm water, to refrigerators, or heating systems such as electronic kettles, microwaves or ovens. A backup system you and/or your family/community could install would be solar panels, to collect power during the day to then be used at night or when needed. Solar panels collect solar energy by catching the sun-rays in the cells of the panels and turning the energy into a direct current (DC), then the panels convert the direct current into usable alternating current (AC) energy with the help of inverter technology. That current is then distributed throughout the building accordingly.
