Battery technology has already made our lives more portable and convenient. From the disposable alkalines you used to use to power your Walkman to the modern rechargeable batteries in your cell phone and laptop, they allow us to take our work, entertainment and communication systems on the go. But batteries might have an even grander destiny: they could revolutionize the way we generate and use energy all throughout the home. Read on for a glimpse into our battery-powered future.

From Electric Cars to Your Living Room

Leading the charge into the brave new world of batteries is Elon Musk, CEO of Tesla Motors. Musk recently launched Tesla Energy, a suite of batteries designed to facilitate flexibility for consumers and ultimately pave the way to an energy grid that doesn't rely on fossil fuels.

"Our goal," Musk said at a press conference, "is to fundamentally change the way the world uses energy."

Tesla used its expertise in designing batteries for electric cars to make batteries bigger and more powerful. The company’s new lithium-ion batteries are optimized to enable “homes, business, and utilities to store sustainable and renewable energy to manage power demand, provide backup power and increase grid resilience,” the company promises.

Energy at Any Time of Day

Because Tesla’s new battery technology allows residential and business users to store electricity until it’s needed, it creates the opportunity to purchase electricity during off-peak time, easing the stress on our electrical grid. It also helps users get more out of sustainable but intermittent fuel sources like wind and solar.

If the technology catches on, consumers can take better advantage of utility time-of-day pricing. Some utilities in North America sell electricity at cheaper rates during nights and weekends, when there is less demand. A homeowner could therefore charge a battery at night and use it during the day, which saves money for them and reduces the generation cost for the utility company by smoothing out the demand.

Furthermore, as solar and wind technologies become cheaper and more viable, the ability to store their output means that they can further cut into the market share of fossil fuels like coal and natural gas, reducing human impact on climate change.

Keep the Lights On and the TV Running

Another advantage of the enhanced storage potential is that homeowners will still have power in the event of a blackout or other disruption to the power grid. And people who want to go off the grid entirely with solar energy can do it without worrying about running out of power during the night.

The batteries are expensive, starting at $3,000 for residential models. If the program takes off, the price should fall and ever-better technologies will be developed to improve storage, capacity, transmission and other specifications.

For now, the Tesla batteries look like a useful, if expensive, addition to the energy-conscious homeowner's arsenal. If prices do continue to fall, however, the batteries could transform into something truly revolutionary.

Right this instant you are probably enjoying light provided by a CFL or an incandescent bulb. Buying and installing this kind of light sources is an automatic process. It`s popular, you buy it and when it does not work anymore you just go to the store and replace it. Little do people know about the hidden dangers of these light sources and their utter inefficiency, not to mention the way they damage the environment.

Let`s take each one and see why they are not the best option.

Incandescent bulbs have been around for a long time, being quite simple and cheap. While in the past they may have been revolutionary, today they are ineffective and their production will soon be stopped. Incandescent bulbs have several disadvantages and can`t even compare to, for example, LED lighting:

Sure, manufacturers strive to create better variations but they are all costly and do not improve the initial concept by a whole lot.

CFL are much better than incandescent bulbs and replaced the latter in many places but they are still not quite the best option, even if they can last up to 12000 hours (no match to LEDs, which go up to 200000 hours). What are the problems?

A deep and attentive analysis like this one reveals just how many things we are used to ignore. Fortunately, a better alternative makes both CFL and incandescent bulbs seem utterly irrelevant. The alternative is LED lighting, a known technology that is now applied to public and private lighting. It is ten times more efficient and it is not a threat to the environment or to you.

If you’re considering buying an electric car (“electric vehicle” or “EV”), you might have questions. Many of the answers given here apply to anywhere in the U.S. But when it comes to rebates and the electricity rates for charging EVs, the info applies to Los Angeles, where I install electric car chargers. I’ve also included a link so that if you live outside of L.A., you can check which rebates or other financial incentives are available in your area.

Do I need an electrician to install a charger for my new electric car? The most common electric car is still the Toyota Prius, which an electrician can’t help you with. You don’t plug it into an outlet to recharge. The battery is recharged by a mechanism that’s triggered when you put on the brakes. With a Prius, there isn’t a worry about running out of electricity. It’s a hybrid, meaning that until the brakes recharge its battery, the car burns gas in its internal combustion engine.

While at this time, you can’t plug a standard Prius into an electric outlet to re-charge the battery, Toyota has announced that its 2014 model will have this capability. The 2011 Chevy Volt (a hybrid) and Nissan Leaf (all-electric) are “plug-ins.”

Level 1 Electric Car Charger. Plug-in electric cars come equipped with a “Level 1 charger.” This is a special extension cord that you can plug into an electrical outlet which carries ordinary house current (110 volts). You may have a suitable electrical outlet right where you need it in your garage or carport. It can charge a Nissan Leaf, empty to full, in about 20 hours. For a Chevy Volt, it takes about 10 hours. Don’t worry, there’s also a faster alternative, a Level 2 charger.

Even if you’re all set up with an outlet in your garage for your Level 1 charger, if you’re not knowledgeable about wiring, have an electrician check things over. The electrician should make sure that the charging outlet in your garage is on a “dedicated circuit,” meaning it serves no other outlets or switches. The outlet should be a GFI (safety) outlet in working order. And the electrical panel should have enough capacity to deal with the added load of charging your car.

Level 2 Electric Car Charger. Most drivers will want the speed of a Level 2 charger. It’s housed in a container about 18 inches around and hangs on the garage wall, sticking out about a foot. It takes a Nissan Leaf from empty to full in about eight hours and a Chevy Volt in about four. This will allow you to charge your car overnight even if the battery starts from empty. Nissan and Chevy have both partnered with manufacturers and installers of Level 2 chargers. Your car dealer can arrange for purchase and installation of the charger, or you can do it on your own.

What does installation of a Level 2 charger involve? Let’s say you decide to go ahead with a Level 2 charger. The electrical contractor will select a location in your garage or carport where a charging cord won’t get in the way. He will consider the location and size of your electrical panel, existing circuits, and where and how your electricity is metered.

He will give you a bid for installing the charger and, if needed, upgrading your electrical panel for the additional load. An electrician who specializes in charger installations can also tell you about tax credits and rebates. Actual installation of the charger along with any needed upgrade of your electrical panel and/or electric meter will take a few hours to a day or so.

Do chargers require an electrical permit and inspection? If you already have a dedicated circuit for a GFI outlet (no other appliance is served by the circuit) in your garage, it can be used for Level 1 charging and no additional permit or inspection is required.

If you need to install a new circuit or new electric meter or upgrade your electrical panel for either a Level 1 or Level 2 charger, you’ll need a permit and an electrical inspection.

How much does installation of a Level 2 charger cost? Without any rebates, installation of a Level 2 charger averages around $2,000. The price for your installation will depend on the distance of your charger from your electrical panel, whether your panel needs an upgrade, and whether you will be installing a special electric meter. Rebates and tax credits can reduce this price if you install before December 31, 2011. We don’t know yet about financial incentives for 2012.

INCENTIVES FOR ELECTRIC CARS The information below on incentives for electric car buyers focuses on L.A. and California. Here’s a link where you can find out more detail about L.A. and also check out incentives for electric cars in other zip codes.

What financial incentives are available for purchase of electric cars? If you purchase an electric car in 2011, you may be able to reduce your federal tax bill by $2,500 to $7,500 with a tax credit. Converting your Prius or other non-plug-in hybrid to a plug-in can reduce your federal tax bill by 10% of the cost of the conversion. Purchase of an electric motorcycle or low-speed “around the neighborhood” electric cart can reduce your federal tax bill by up to $2,500.

Californians who buy an EV and act quickly enough can qualify for a rebate from the State of up to $5,000 on an electric car and up to $20,000 on a commercial vehicle. These rebates apply to many kinds of electric vehicles, including all-electric, hybrid, motorcycles, and low-speed “around the neighborhood” carts.

What rebates are available for installing an electric charger? A homeowner who installs a Level 2 electric charger can cut their 2011 federal tax bill by 30% of the cost of purchase and installation, with a cap of $1,000 (as a tax credit).

If you are customer of the L.A. Department of Water and Power (LADWP), you may qualify for a $2,000 rebate on installation of your electric charger. To qualify, you need to also install a separate electric meter for your new car. Ask your electrician to see if you will save money with this approach.

Are there any other incentives for electric car owners? Some states, like California, provide a sticker to qualifying electric car owners so that they can drive in freeway carpool lanes regardless of the number of occupants.

Does EV charging receive any special break in electric rates? In Los Angeles and many areas of the country, yes. In L.A., both Southern California Edison (SCE) and the Department of Water and Power (LADWP) offer special reduced rate plans for charging EVs at night, during off-peak hours.

Both power companies encourage people thinking of buying an EV or installing a charger to contact them. Call (800) DIAL-DWP or call SCE at (800) 4EV-INFO. SCE has extensive information on its website at www.sce.com. Both companies are particularly interested in customer plans regarding EVs because they need information for planning power demand.

Are electric car chargers safe? At this time, all the evidence points to extreme safety. At Level 1, the EV charging cord is plugged into a GFI outlet carrying ordinary house current (110 volts), very much like outlets in newer bathrooms and kitchens. GFIs are specially designed to protect people against shocks. Should something go wrong, like the outlet gets wet while charging your car, the GFI immediately shuts off power. Homeowners and businesses have many years of safe experience with GFIs.

Level 2 chargers carry more current, 240 volts. Manufacturers have designed Level 2 chargers for every eventuality and advertise that Level 2 chargers are 100% safe. Of course, nothing is 100% safe. But, so far there have been no reports of someone figuring out how to injure themselves with one.

Do all chargers serve all electric vehicles? Your new electric car will come with a Level 1 charger that is compatible with any ordinary electrical outlet.

The manufacturers of Level 2 chargers have worked out universal standards. Regardless of the make of your electric car, any Level 2 charger will be compatible with it.

Where can you charge an electric car in Los Angeles? Level 2 chargers are currently available for a fee in Los Angeles train stations, LAX, the Bob Hope Burbank airport, the L.A. Convention Center, and other public places. Click here for an on-line map of electric car chargers. You can type in your zip code to find publicly-accessible chargers near you.

As a Top Plano Electrician, I know better than anyone how powerful and useful electricity is. It also makes me more aware of what most people tend to ignore or forget: electricity is dangerous. Electricians are required by law to carry insurance, and for good reasons. Electric current is capable of starting fires and destroying your property and equipment in a matter of moments. The proper safety precautions really can save lives, and there‘s always something we can do to improve home safety.

One of the most important precautions is located in your electrical panel: the circuit breaker. It is designed to keep you from using more electricity than the wiring or receptacle can handle at one time, what we refer to as overcurrent protection. This protects your wiring from taking on too much current, which can cause the coating around your wiring to melt, the leading cause of electrical fires. Circuit breakers serve another purpose as well; not only to protect from surges coming from outside your home, but from potential hazards within it as well. Current flowing through a failed piece of equipment or appliance can cause sparks, which have the potential to start fires or damage other electrical devices. A properly functioning circuit breaker can shut off the power to this device. It’s very important, however, that you use a circuit breaker of the proper size for the circuit to ensure that your wiring is properly protected.

Circuit breakers come in specialty varieties as well; the most important are ground fault circuit breakers (GFCI), for wet locations, and arc fault circuit breakers (AFCI). AFCI’s, in particular, can help prevent some of the most common dangerous situations in your home.

I’ve dealt with plenty of cases where electrical fires have started because people ran an extension cord under the carpet, so that they can power the lamp in the center of the room. Over time, people walking over the cord stretches out the wiring, making it so thin that the current overloads the thinly stretched wire, creating an arc fault; the electricity “jumps” the wire, completing the circuit in a way the cord can’t handle and generating heat that starts a fire. Arc fault circuit breakers prevent this by shutting the circuit down when the arc fault occurs.

So what do you need to know about arc fault circuit breakers? To start with, by code AFCI’s should be installed on any circuit that isn’t protected by a GFCI or directly wired into an appliance. It’s in your best interest to have your safety devices routinely inspected to maintain their optimum performance and capabilities; in particular, your circuit breakers should be inspected at least once a year. The inspection process is quick and relatively inexpensive, and something that simple really can save the lives of you and your family.
