Today, security patches often are not supplied to end users, or users are not applying the patches, as they fear they will affect system performance. Locally-generated electrical energy, such as that from photovoltaic systems, needs to be stored during accumulation cycles for use during peak demand cycles. Electric power utilities also typically own and operate at least certain portions of their own telecommunications systems, which often consist of a backbone of fiber optic or microwave links connecting major substations with spurs to smaller sites. It is said that Alexander Graham Bell would not recognize the components of modern telephony fiber optics, cell phones, texting, cell towers, PDAs, the internet, etc. It uses a 32-bit microcontroller to effectively monitor the fire hazards that may occur in the protected electrical circuit due to leakage, temperature, and current overload, and handles the remaining current in real time. To cause physical damage equivalent to that from a small to moderate-size tornado would be extremely difficult, even for a large, well-organized group of terrorists.
