Rolling blackouts occur when delivery of electricity from a large power source is intermittently stopped in varying places across a wide area. Rolling blackouts usually occur in tandem with natural disasters or energy crises.

Rolling blackouts prevent large power sources from blacking out completely. They have been implemented in places with a high demand for electricity, such as Japan, the U.S., Pakistan, and Ukraine.

By limiting the amount of power that can be used at one time to only certain areas, power station operators can control the power output from their generators. Should a part of the generator be at risk for failure, operators can begin a rolling blackout to limit the amount of work the generators must do. From there, they can pinpoint the problem areas and find a useful fix without taking away power from an entire area.

Rolling blackouts can prevent power outages from:

In the case of power output problems like station faults, short circuits, and electrical overloads, a rolling blackout can mitigate the risk of explosion and prevent the acceleration of large scale disasters.

Since power can only be distributed over a limited area, 100% of the electricity supply to some places will be temporarily cut off. Household items such as lights, outlets, and appliances will cease operation for a predetermined amount of time. You can gather information about rolling blackouts from the radio or news before they occur.

You should have an emergency kit in your home or business that has the necessary supplies for survival without electricity. Items to include in an emergency kit are:

Be sure to lock all of your doors and windows if possible. In developed countries, law enforcement will bolster its forces to protect areas affected by a rolling blackout. You should still remain safe and prepared whenever possible.

Should a rolling blackout elevate to a blackout, don’t be afraid to use your supplies. Even if electrical generators are running at low capacity, they still have the potential to cause larger problems should they become overloaded. A rolling blackout can quickly become a city-wide blackout.

Rolling blackouts are relatively rare. Conditions must be extreme for a rolling blackout to take effect. While the climate in the U.S. varies widely across the country, devastating natural disasters don’t compromise the electric grid more than once every 20 years.

What is Valentine’s Day –  Valentine’s Day is named after Saint Valentine, but the legend of St. Valentine is shrouded in mystery.    One legend is that Valentine was a priest who served during the third century in Rome.  The Romans were at war, and the Roman Emperor at the time decided that single men made better soldiers than those with wives and families.  The Emperor forbade men to marry.  Valentine realized this was an injustice and continued to perform marriages.  Another legend states an imprisoned Valentine actually sent the first “Valentine” greeting to a young girl from a jail cell.  A common thread is that most St. Valentine stories suggest he was a heroic and romantic figure.

Why Valentine’s Day?At the end of the 5th century, Pope Gelasius declared February 14 St. Valentine’s Day, but it was not until the Middle Ages, that it was considered a day for romance.  Sending Valentine greetings was made popular in the Middle Ages as well, although written Valentine’s didn’t begin to appear until after 1400.

Valentine’s Day cardsValentine’s Day is celebrated in the United States, Canada, Mexico, the United Kingdom, France, and Australia.   By the early 1900’s printed Valentine’s Day cards began to replace hand written romantic Valentine’s notes.

Esther A. Howland began selling the first mass-produced valentines in America. Howland, is known as the “Mother of the Valentine.”  In 1847, she received an English Valentine and became fascinated with the idea of making similar Valentine’s.  She began taking orders for Valentine’s and soon the demand outweighed the amount she could make, so a company was born.  It is estimated she made more than $100,000 annually selling Valentine’s cards.

Fun Valentine Facts:

If you're ready to take the plunge and purchase a state-of-the-art home theater system, you have more to consider than just the equipment you intend to purchase. Even if all of your components are top-of-the-line, you won't get the most bang for your buck without professional design and installation.

To make sure you get the home theater of your dreams, it's important to consult an electrician early on in the process. A quick electrical inspection of your desired theater space will help you understand what kinds of electrical upgrades you might need to set up a media center that is functional, safe and that provides the highest quality viewing experience.

Handle the Load

A big-screen TV by itself won't strain the electrical system in a modern home. But factor in a disc player, set top box, stereo receiver and multiple speakers, and you might be talking about a serious electrical load. A licensed electrician can easily test your system to ensure it's ready to power your dream theater. If upgrades are necessary, you can take confidence that new wiring or circuits will be installed by a qualified professional.

Hide the Cords

Wireless speakers and other multimedia components might seem like an attractive option because you want a streamlined look, but you'll often sacrifice a great deal of quality by cutting the cord. Instead, let an electrician make a plan for hiding all of your home theater's power cords away so that the room looks great and there's no risk of tripping in a darkened room. Without tearing up your decor, a professional installer can run cables within your walls and install new outlets to avoid that snarl of wires.

Protect Your Investment

You probably already use a surge protector to safeguard your home computer against the threat of power surges. But your home theater equipment is just as vulnerable, and a single lightning strike can turn thousands of dollars in equipment into trash. While you can protect your home entertainment technology using surge protection adapters, the best solution is to install a whole-home surge protection system. There's no need for clunky power strips, and your entire home's electronics and appliances will be safeguarded.

Unless you have extensive electrical experience, don't go it alone when setting up your home theater. Make sure your design is smart, safe and spectacular by enlisting the talents of a licensed local electrician.
