A recent TedTalk about LED lights has garnered about a million and a half views. That high number isn’t surprising, given that LEDs have been making headlines a lot, lately. Tons of informational articles about the efficiency of LED light bulbs and how to choose them have been circulating online. But this TedTalk is about something quite different – data transmission.

A significant number of homes in Baltimore and Bethesda, MD, Alexandria, VA, and Washington, DC built between the mid-1960s and the first half of the 1970s have hazardous aluminum wiring rather than copper. During that time, aluminum wiring was considered safe to use and viewed as a cost-saving measure. The U.S. Consumer Product Safety Commission (CPSC) now believes aluminum wiring poses a safety hazard in homes that still have this type of wiring.

The biggest danger associated with aluminum wiring is that unanticipated fire hazards arise from the oxidation and deterioration caused at the points where aluminum wiring is connected at outlets, light fixtures, and splices. While this can cause overheating and arching that won’t trip a circuit breaker, it can cause a fire. Aluminum wiring was used in an estimated 2 million homes between 1965 and 1973—and many of these homes are located in the MD, VA, and DC area.

If you’re concerned about dangerous aluminum wiring, pay attention to the following warning signs:

All of these signs indicate a potential fire hazard for standard aluminum wiring.

Aluminum wiring should be thoroughly evaluated by a qualified electrician who is experienced in inspecting and correcting wiring problems. The CPSC recommends a few methods for correction. The first is to rewire the home with copper wire, an expensive option that really only makes sense if the homeowner is already in the process of completely remodeling or doing deep renovations. The second option is to use the Copalum crimp method to correct the problem. This involves attaching a piece of copper wire to the existing aluminum wire with a specially designed metal sleeve and powered crimping tool. It is a permanent repair option that will eliminate the dangers posed by aluminum wiring. A third option is to use a UL listed copper to aluminum connector to attach a copper wire to the existing aluminum wire.

Only an experienced electrician can accurately determine the level of danger a home with aluminum wiring faces, and then fix the problem in an efficient, timely manner.

Pay as you go electricity plans allow consumers to pay for their electricity in advance. The plan, which uses prepayment meters, helps consumers to monitor and control the way they use electricity. This saves on energy costs.

Keypad based prepaid meters: This meter has a keypad to input the electricity token number. Consumers purchase the credit using a variety of methods. These include visiting the agent, paying through banks or mobile payments in some countries.

Key meter: Consumer uses an electronic key loaded with the tariff information and credit.

One way card system: Uses a disposable card. The user purchases power with a reloadable debit card. The loaded card is then passed near the meter, which has an in-built card reader.

Two-way card systems: Uses a smart card and the meters have a real-time, two-way communication capability. It is one of the most secure, but more complex and expensive methods to implement.

These allow consumers to interact with their meters and query balances using their mobile phones by sending an SMS to a monitoring system. In addition, the user is able to track electricity use by the hour, day, month or annually using the phone or online access.

These smart prepaid meters offer easier top up options. They include online payments or by text, as well as scheduled and auto top-ups.

When using a prepaid meter, the customer must keep track of the remaining credits and replenish to avoid disconnection.

Ensure there is enough credit when going away for long periods. The meter will continue collecting the standing charges even when on no load. Consumers should ensure they have enough credit to last until they return.

Some crooks will take advantage of the consumer’s lack of knowledge and offer them cheaper credits than those bought directly from the utility company. For example, they will sell their credits at half price. This is more common with Key Prepaid Meters and the crooks will usually have master Keys, which they use to top off the consumer’s meter.

If the energy company finds out, the consumer ends up paying twice for their electricity; first to the crook, and then to the energy company.
