Electricity exists everywhere, from high voltage power lines to phones and computers. Understanding the basics of how it works remains essential to using it safely and efficiently.

When electricity travels from a positive lead to a negative lead in a circuit powered by a battery, it is considered direct current. This type of current powers electronics, LED lights, and cars. Alternating current is generated from rotation, usually by a generator. The direction of the current and the voltage flips as the generator completes a rotation. The faster the generator spins, the faster the flipping of current direction occurs. In North America, the typical frequency of AC power is 60hz or 60 alternations per second. The advantage of AC power is that the voltage can be stepped up easily by use of a transformer, which allows high voltage transmission. AC power is also useful for electric motors.

Specifically, power is a measure of energy usage over time. The standard unit of power is the watt and calculated as P (watts) = V (volts) x I (amps). Utility companies sell electricity in units of kW*h (kilowatt hours), which is simply one kilowatt of power delivered continuously over one hour.

The storage of Storage of renewable energy with Wind and Solar for daily use:

Photovoltaic and Wind technology together make this really cool. When you add power storage with renewable energies, these automatic transferred units can be programmed to “sell back” electricity when electrical demand and storage capacities are satisfied. All of this is programmable in any order/sequence desired. By putting the units side by side, these systems can produce 240 volt single phase or three phase power with a pure sign wave.

Here is a great example of a real world solution that we call the Power Cart. This example utilizes solar panels, yet wind power could be added to the system very easily. This Power Cart system provides 20,000 watts of usable power, rechargeable through 4 solar panels, offering any home or business the ability to create, store, and use their own renewable electricity on a daily basis, and maintain power in the event of an outage.

Power Cart will have a Continuous Output of 3.6KW with a 9KW Surge start. This 48 volt grid interactive Outback power plant has 60 amp input/ output, and a UPS 60 amp transfer switch. It works from batteries, generator, or grid and can be charged by sun, wind or any type of generator or from the utility grid. Recharge can be programmed to take advantage of these in any order or percentage you desire. It is internet programmable and monitorable taking over 400 screens in excess of 10,000 commands – including the most important one ‘Let me work on automatic and don’t bother me.’ Also included is complete DC protection from the array to the charger, and from the batteries to power plant& AC protection via 60 amp breaker outlets (wired per country – as per order) also available in any output voltage ex. 100-150 volt, in 50 or 60 cycle.

From the standard AA battery to the relatively unknown LR44 battery, everyone everywhere should embrace all things battery operated on February 18, also known as National Battery Day.

The  “battery” can trace its routes to Benjamin Franklin who coined the term. In 1800, another inventor, Alessandro Volta created a steady current for a length of time using zinc and copper plates and brine soaked paper disks. Eventually, this primitive experiment in electricity would lead the way to the batteries we know today.

So don't be negative because Mr. Electric® has some positive reasons to celebrate National Battery Day.

Whether you have four, six or eight cylinders under the hood, chances are you only have one battery. No car or truck can run without it. So when you get in your ride on National Battery Day, take a minute to thank the true workhorse of the vehicle; the battery.

When it comes to handheld and portable electronic devices, not a single one would work if it weren’t for the battery. These devices would do little good for people on the go if they stopped working every time they were unplugged from the wall. Thankfully, batteries that drain slowly over time allow for us to be portable and still be connected to the digital world. All of this is made possible by the battery.

Battery operated drills and saws have made working at the construction site or doing home renovations a breeze. Workers can cut boards and build for hours before simply changing out the batteries. Once the workday is done, workers can charge the batteries over night and start again the next morning. With the advent of cordless tools, tripping hazards can be avoided. Blown fuses and tripped breakers are a thing of the past, all thanks to the battery.

On February 18, go out into the world with a positive attitude and change those who are negative around you by reminding them of everything the battery does on a daily basis. Who knows, doing it may give you a charge!

Improving your home energy efficiency is a worthy and admirable goal. You can help reduce your impact on the environment while saving money with savvy decision making. However, the up-front investment for some efficiency upgrades is substantial, so always do your due diligence before you find electrician services and commit to buy. Read on to clear up some misconceptions about home efficiency and make sure your money is being put to good use.

You Don't Have to Sacrifice Your Comfort: It's true that the best way to conserve energy is to use less of it with strategies like turning off the lights or keeping the temperature lower in the winter. But that doesn't mean you have to sit shivering in the dark. The key to efficiency is to get the same amount of utility for less energy input. That means replacing old incandescent bulbs with LED versions, or investing in better HVAC technology like a smart thermostat. That way, you can keep your home environment tuned to your comfort while reducing consumption at the same time.

Don't Rush into a Big Ticket Item: The most dramatic way you can upgrade your efficiency is with a brand new heating or cooling system. Equipment efficiency has improved drastically in recent years, and new technologies like geothermal heat pumps, biomass boilers and solar panels can all reduce your bills dramatically. However, they aren't risk free. You’ll often face a significant up-front investment when you find electrician services for these installations, and the actual savings that you will realize can vary widely based on factors like the price of fuel. You could also see a loss if you make a big purchase and decide to sell your home soon after; there’s no guarantee you’ll recoup the cost in the selling price.

That's not to say you should avoid large efficiency investments – just look before your leap. You will get the best return from these items if you already need to replace outdated equipment anyway, and if you plan to stay in your home for many years. To reduce some of the upfront costs, you can also look for federal tax credits that refund up to one third of what you spend, as well as options to lease solar panels so you don't have to put any money down at all.

Don't Forget the Insulation: On the other side of the coin, new HVAC technologies won't do you much good if all that treated air just leaks into the outdoors. One of the biggest ways you can improve your efficiency is by plugging leaks and upgrading your insulation, which is typically a much cheaper fix. With a leak detector, some caulk and spray foam insulation, you can seal up your house with minimal investment, saving you money in the short term as well as preparing the house to get greater efficiency out of newer technologies.

For more straight shooting about how to get the most value for your efficiency investments, find an electrician to conduct an energy audit on your house. Your local Mister Sparky® is always available to help!

The jargon in the lighting world can often get mixed up. Color rending index (CRI) and color temperature are one of the most to be confused with each other. This post is going to clarify what the different between CRI and Color Temperature is so we can end this confusion.

Here is a short explanation why the CRI is more important to focus on before deciding for a color temperature. The color rendering index is the most important feature in certain applications as it determines the appearance of objects, faces and spaces. If this aspect is not relevant, the CRI can be as low as 60 or even 40.

The color rendering index (CRI) is a numeric evaluation of the light color accuracy with the reference of daylight (numbered 100). Sunlight and its broad spectrum will enable a person with normal vision to see 68 different colors in a color chart, but if the chart is illuminated by a light source of one wavelength only, each color from the color chart will appear as a different brightness of that one color. Some activities, such as walking or operating a vehicle, do not require the accurate perception of surface colors while others such as product selections in shops benefit from better color rendering features. Look at the application of the lighting installation. If the visual tasks are easy to perform the CRI doesn’t need to be high. In areas like offices, handcraft manufacturing and surgery, the requirements for visibility, contrast, visual guidance as well as face recognition need to be provided by a lighting system with a good CRI of >80 or even >90.

How much is the light color affecting the space? The term color temperature describes the temperature of objects by which they emit light, modeled through the “blackbody radiator”. When increasing the temperature of a “blackbody”, it starts to emit visible light in a continuous spectrum. The filament of a 60W incandescent lamp heats up to about 3000°F, as a result the lamp emits light with a color temperature of 3000K. Many of our artificial light sources do not create light by heating up a material until it glows like an incandescent lamps. Instead of creating a continuous spectrum, they generate an assortment of color emission lines. A blackbody color temperature cannot be directly given to this non-blackbody type of emission, generated by high intensity discharge and fluorescent lamps for example. For those light sources, a correlated color temperature (CCT) is indicated, based on the blackbody color temperature. A cool white fluorescent lamp has a CCT of about 5000K. The lamps light spectrum is different from a blackbody one but has the same temperature.

The light color influences the atmosphere in a space. The more cozy the ambiance the warmer the light color (lower color temperature) should be and the more dynamic the scene the cooler the light source (higher color temperature). The CRI is the most important factor to watch when choosing light sources. How good is the light source representing faces, colors and contrasts? The easier the visual task and perception the lower the CRI can be. The color temperature needs to be watched second, it is supporting the space’s atmosphere.

Conclusion

There you have it; an explanation of both the Color Rending Index and Color Temperature.
