Have you ever wondered just how that electricity got to your light bulb or microwave?
The electricity powering your light bulb is produced in a power plant by generators. Energy cannot be created or destroyed just changed from one form to another. Newly generated electricity is then transported over the power grid to your electrical outlet.
The United States has three power grids that keep the lower 48 states powered:
- The Eastern Interconnected System east of the Rocky Mountains
- The Western Interconnected System from the Pacific Ocean to the Rocky Mountains
- Texas Interconnected System
These three separate systems are interconnected and require constant oversight to ensure that all the components are linked together. Since large quantities of electricity cannot be stored effectively or efficiently, electricity must be produced as it is used, this increases the need to watch over the grid. Control centers are utilized to monitor the supply and demand to safeguard against blackouts. To avoid blackouts there must always be a perfect balance between supply and demand.
From the control centers electricity is constantly monitored as it travels from the power plants to high-voltage power lines that transport electricity throughout the three grids. The higher the voltage the more efficiently they transport electricity. In other words the higher the voltage the more electricity will get to the end point. However, there will always be losses as electricity flows through the power grid.
From the high voltage power lines the electricity is “stepped-down” to lower voltage power lines, utility poles and wires before it can be safely used in your home or office.

Are vampires sucking your electricity?
Standby or vampire power as it is most commonly referred to, wastes $10 Billion of Electricity Annually in the United States alone. The average US household has about 40 electronic devices that constantly draw small amounts of power.
Top 10 Energy Vampires in Your home
- Laptop computer chargers
- answering and machines
- Computer printer
- TVs and cable boxes,
- VCRs, DVD players, DVD recorders, digital video recorders,
- phone and iPod chargers
- hubs and routers,
- video camera battery charger
- plugged-in electric toys
- night lights

Researchers are generating power using viruses
This might sound weird but researchers at Berkeley Lab have developed a method to generate power using a virus.
The harmless M13 bacteriophage virus converts mechanical energy into electricity, and is the first generator to produce electricity by harnessing the piezoelectric properties of a biological material.
Testing the generator produced enough current to run a small liquid-crystal display. Image courtesy of Berkley Lab
This new technology will one day make it possible to charge your smartphone as you walk, thanks to a paper-thin generator on the sole of your shoe. Can you imagine all the other great uses for this type of generator.

ComEd Outage Alert Map and Mobile App
ComEd has announced two new ways it is utilizing technology to improve communication with their customers. The first is an interactive online outage map and the second is a mobile application for smartphones.
“These new features are just two of many improvements ComEd has made in recent months as part of our focus on delivering greater value to our customers through enhanced customer service,” said Terence R. Donnelly, executive vice president and chief operations officer of ComEd.
ComEd’s interactive outage map allows customers to report and view current outages. The color-coded triangle icons illustrate how many customers are affected by each incident, as well as pinpointing the outage location.
Zooming in on a specific area gives more details such as Customers Affected, Estimated Restoration and Crew Status. The map is updated every half hour, and a mobile version is in the works as well.
When you zoom in on the ComEd Outage map more details are shown
The interactive outage map can be found on the ComEd website www.comed.com under the Customer Service tab, along with other useful outage information or by clicking here www.comed.com/map.
The new ComEd Mobile App like the outage map will allow customers to report power outages and check restoration status. ComEd residential customers will also be able to use the app to view account information such as:
- Account balance
- Account history
- Manage payments, including budget billing, automatic and one-time payments
- Report meter readings
The ComEd mobile app is free and available for download on iPhone and Android devices on the ComEd website www.comed.com/app or by searching for “COMED” in the application store on your smartphone.

Outdoor Electrical Safety
Did you know that May is National Electrical Safety month? To celebrate Realgy Energy Services has compiled a list of the top 10 tips to keep you safe while outdoors.
Electricity can be very dangerous if not used correctly, but sound safety practices can help minimize electrical hazards and cut down the risk of accidents.The more you know about electricity, the safer you will be both at work and home.
10 outdoor electrical safety tips
1. Never use electrical equipment or tools near pools or other wet areas, such as wet grass. Always use extension cords rated for outdoor use.
2. Be aware of and stay at least 10 feet from overhead power lines when carrying and setting up ladders or when using long-handled tools.
3. Call before digging. Call 811 to locate any underground power lines before digging. For more information check out the call 811 website
4. Get help installing antennas if needed. Remember to keep yourself, tools, materials or equipment at least 10 feet away from any overhead power lines.
5. Fly kites and model airplanes in open areas well away from trees and power lines.
6. Inspect all outdoor power tools and electric lawn mowers for frayed power cords, broken plugs and cracked or broken housings. If the cord is damaged, stop using it.
7. Never climb or play in trees that are near or touching power lines.
8. Do not play on or with utility poles, this includes throwing objects, such as sneakers, at or onto electric power lines.
9. Use caution when trimming trees. Before attempting any tree pruning, look for overhead power lines that may be near and/or hidden by the tree foliage. If in doubt hire a professional qualified contractor.
10. Always assume electric lines are live and treat them with caution and respect. Even low-voltage electric lines and cords can be hazardous if damaged or improperly handled.
If you are ever unsure about the safety of electrical wires or another form of electricity either at home or at work contact your local utility. You can find an emergency hotline on most utility invoices if there is not emergency number call the customer service number.
