Hurricane Sandy left many without power, but generators can light the way. Electricity from the utility company is great, that is until something interrupts it and it goes out. Power outages can be troubling and even life threating, so don't get caught without a backup generator system of some type to keep the power flowing. Backup generators come in many different styles. There are generators that connect to PTO drives on tractors, portable generators that run on gas, diesel, or propane, and others that connect more permanently to serve as a whole-house backup that run on propane or natural gas.
Generators are in great demand in the hurricane-stricken East Coast.
