Several of my friends who are sort of preppers have bought generators for emergency use. Myself I do not consider generators a high priority. It comes behind food, bandages, and self-defense. While a generator is great for short-term power outages, for long-term use it has some problems. For many of us money is a problem and we must set priorities.
I know people who have spent a thousand or more dollars on a generator and have 5 gallons of fuel on a good day. This money could have been put to better use buying food etc. Depending on where you live the use of generators may be limited by their noise and light. You may have problems with operational secrecy.
Before you purchase a generator do some research and make sure it will meet your needs. Take into consideration the items you want to run and their wattage. Be sure you generator is capable of supplying that much power. Know how much fuel your generator uses per hour and how many hours you will run it per day. Will it attract unwanted attention?
Plan for fuel storage and be sure you can store it legally and safely. Whether it is propane, gasoline or diesel it all has storage problems. Gasoline and diesel need to be rotated. Propane is the easiest to store but should be stored downhill from your house. Remember it is heavier than air and in case of a leak flows downhill like water.
Tomorrow I will discuss fuel storage.
