Nearly every single person living in the United States relies on the electrical grid. It's how electricity gets from the power plant to your home, powering your devices and appliances. With no grid, none of the electrical work in your home will function – no television, no air conditioning and no electric lights. Our grid is changing, however, taking advantage of evolving technology on both the distribution and consumer side of the equation. Read on to learn more about how our electrical grid will evolve to meets the needs of the 21st century.

How to Balance Supply and Demand

The electrical grid is not a single object, but rather a giant network of power plants and transmission lines that spans the entire nation. In order for electricity to flow from the generating stations into your home’s electrical work, the grid needs to be able to meet the demand at any given time and place. This can be an enormous challenge – if there is too little production, consumers can be subject to annoying and damaging brownouts. Ramping up generation to meet variable demand is expensive and inefficient, however.

Some utilities solve the problem with time-of-day pricing, charging more during the day and less at night to smooth out demand. Smart technology, however, will allow us to fine-tune the grid even further to increase efficiency, improve communication and mitigate blackouts or other power outages.

Smart Meters and Dispersed Generation

Smart meters are one of the first steps toward our new grid. These meters track residential electrical consumption in real time and can communicate with the utility company instantaneously. They can allow producers to better predict demand, respond immediately to dips and spikes, and further refine variable pricing structures that incentivize people to use less electricity during peak hours. Smart meters also give homeowners the power to see where and when they are putting the most stress on their electrical work, allowing them to adjust their behavior strategically.

Changes are coming to the generation side as well. Traditionally, the electrical grid is powered by large, centralized power plants, but residential solar installations mean that generation is becoming more widely distributed. Wind generation is also becoming an ever-larger factor in our nation's energy supply. This means that the grid needs to be updated to become more flexible and adaptable, but there is a large payoff in sight – the more dispersed that power generation becomes, the more resilient the grid will be in the event of an outage, with smaller regions able to supply themselves with emergency power if they are cut off from the centralized system.

Makes Tomorrow's Energy Grid Work for You

No one knows exactly what the power grid will look like 100 years from now, but the nation is well on its way to updating its electrical infrastructure to meet the needs of this century. If you have any concerns about how your electrical work will interface with the power grid of the future, or need any other work done on the wiring and circuitry in your home, call an expert electrician today.

Technology giant Google made its start as a search engine, subsequently branching into email, cloud storage, advertising and so much more. Now the company from Mountain View is surging forward with a new application, promising to tell consumers if their roofs are suitable for installing solar panels. The program, called Project Sunroof, works in conjunction with Google Maps to analyze your roof's size, orientation and shade levels to tell you at a glance how much solar energy you could get from it. Read on to learn more about how this convenient software works and how it can help you.

A Mix Between a Solar Electrician and a Search Engine

The program is simple to use – all you have to do is enter your address, and Google does the rest. According to the company, the program analyzes all of the following to determine how much sunlight you can soak up:

The program also provides information about what tax credits are available in your area as well as the local rules regarding selling solar energy back to the utility company when your panels are producing more than you need. It then spits out a recommended installation size, which you can modify based on how much electricity you actually consume according to your average electricity bill.

Pay Nothing and Start Saving Today

Google's entry into the solar market comes at a time when the options for solar are expanding, including the ability to lease panels from solar companies and enjoy savings on your utility bills while paying nothing for the installation and setup. A good setup can last for 30 years or more, with little to no maintenance from an electrician once the installation is completed.

Of course, solar isn't for everybody, since many roofs might be too shaded or otherwise not suitable, and some states still don't have good solar policies. Therefore, Project Sunroof can be a good place to get started to see if your house is a prospect before you even call a solar electrician. Currently, the program is working on a trial basis in Boston, San Francisco and Fresno, with more cities sure to be on the way.

Don't Forget About Human Experts Just Yet

Of course, even a technology company as powerful and ubiquitous as Google can't fully substitute for an experienced solar technician when it comes to analyzing how you can benefit from panels. If a Google query indicates that your home is a good candidate, have a qualified electrician or solar expert make the final determination and help you decide if solar panels are right for you.

Although LED T8s have not been around long enough to produce a thick memoir, there are some interesting things to note about why they exist.  A few years ago, there was concern that the rare earth metals used in fluorescent tube lamps might start getting significantly more expensive for the U.S. to purchase from China. Light bulb manufacturers began an arms race to develop an affordable and effective LED T8 replacement tube.

A sustained sharp increase in the price of phosphors never really happened. And so LED T8s have gained momentum in their evolution, organically evolving to better perform well in certain applications. Their price point has decreased, and their performance has gone up. And now, LED T8 linear lamps are certified by the DesignLights Consortium to be high quality, high efficiency lighting products.

However, LED T8s continue to be very controversial – even divisive – in the lighting world. Many people think they’re great; but some people think their existence is entirely unnecessary. Both sides of this argument tend to contextualize their visions of the merits and pitfalls of the LED T8 in a comparison with the merits and pitfalls of the traditional fluorescent T8 tube light.

LED T8 Linear Light Bulbs vs. Fluorescent T8 Linear Light Bulbs

First of all, the merits of fluorescent T8s cannot be overstated. Fluorescent tube lamp technology has been developed over decades and is now basically mastered. Fluorescent T8s are extremely inexpensive and have ridiculously long rated lives. In fact, in some cases, fluorescent T8s can last as long as LED T8s!

And it doesn’t stop there. The production of light with fluorescent tube lamp technology works really, really well. It is probably at its peak in terms of performance and cost. Fluorescent T8 light bulbs can last 50,000 hours. And despite their not-always-positive reputation for rendering color, fluorescent T8s can achieve high color rendering indexes (CRIs). But, it must be clearly noted, fluorescent T8s get more expensive as you seek a higher CRI.

And in terms of cost, let’s just say it straight: In many applications, the LED T8 tube light’s initial cost doesn’t make sense when compared to the relatively low cost of fluorescent T8s.  For example, at this stage of the game (June 2014), lighting large spaces like classrooms or large offices is job better performed by fluorescent T8s than LED. First, there’s the cost. Fluorescent tube lamps last long, cost little, and give off crisp light. Furthermore, fluorescent tubes give off light omnidirectionally, casting light upwards toward the ceiling as well as downward. This makes a space look more fully lighted. LEDs, in contrast, are generally more unidirectional and cast light downward only. This is something that will change, but, currently, this is just affirmation of the fact that fluorescent T8s reign supreme for some applications.

Fluorescent T8s often take a while to come on; they’re adversely affected by temperature (and somewhat sensitive about it); they can flicker often; and if the lights are turned on and off frequently, as in laundry room or bathroom applications, for example, they can fail quite prematurely, to the dismay and annoyance of everyone involved. And then there’s that toxic mercury vapor which poses danger to humans and the soil on which we live.

Oh yeah, fluorescent tube lamps require a ballast, too: A component that will also, eventually, fail.

Now, let’s give some attention to LED T8 tube lamps. It should first be noted that LED T8s have a higher initial cost than fluorescent T8s, which can be purchased for only a few dollars in some cases.

Despite their higher cost, LED tube lights have some nice advantages. First of all, LEDs love the cold, so they are great in cold weather applications, unlike fluorescent T8s, which become seemingly infirm in the cold, slow to turn on and flickerish. Basements, sheds, garages, porticos, covered pathways, bathrooms, etc, are great places to utilize the LED T8 linear lamp.

You also have to consider that if an LED T8 tube breaks, it will not release harmful mercury vapor into the air. Mercury from fluorescent tubes can get into the air but also the water supply, which is why you have to recycle them. For some people, the whole mercury thing is enough to open their minds to alternatives to the long-reigning fluorescent T8.

Plus, you can get better color rendering with LEDs than with fluorescent lights. Fluorescent lights work by transforming ultraviolet radiation into visible light. If you have a vague idea about what UV light is, you know that it’s the part of the light spectrum that’s just past the blue and violet area. Even with a rudimentary understanding of light, then, it’s easy to see how the result of transforming UV light into visible light would leave you with a bluish result. As a result, in general, fluorescent lights do not render reds well.

LEDs exude very little to no UV or infrared radiation, both of which fade the color of displayed objects including wall art, furniture, and even rugs. Fluorescent tubes – did you know this? – do indeed fade sensitive belongings over time.

Finally, LED tubes do not generally require a separate power supply. They run on line voltage and require no separate drivers, ballasts, or transformers. That’s one less thing that can break. In conclusion, LED T8s are more expensive than fluorescent T8s, but LEDs are safer, render color better, require no ballasts, operate better in the cold, and do not decline significantly in lifespan due to frequently switching on and off. This means that there are some applications, like cold places, bathrooms, basements, laundry rooms, kitchens, closets, storage rooms, walk in refrigerators or freezers, or places where there’s a risk of broken light bulbs like gyms, warehouses, etc, for which LED T8s might be the better choice. And since LED T8s don’t weaken with frequent switching on and off, they are great for use with occupancy sensors.
