Electricity may either be connected by 230 or 240 volts (these are called single phase circuits that are installed in most residential applications), or 400 & 415 Volts (3-phase). The latter are typically best-suited to provide power to heavy-duty appliances and equipment and in industrial settings as well as larger commercial applications.

Some people have electric kilns installed in their homes or garages because they indulge in making pottery or ceramics products. Certain homes have very elaborate and large, ducted air-conditioning systems. In all these situations, a 3-phase circuit would be required to support this heavy power usage.

The type of circuit used is dependent in the equipment or appliances installed on your property. It is important that you check the power & voltage requirements of the installations properly, before deciding what type of circuits you need. In most instances, even massive ovens and high energy-consuming heaters are typically singe-phase.

This current in amps has to be multiplied by the voltage to give you the power in watts. If a 3-phase supply is available, the total voltage of 24,000 watts will be divided by 3; this means 8000 watts will be used in each phase. This means the current in each phase is lower than 1/3rd of what it generally is in a single phase power supply (about 30 amps in each phase instead of 100).

The aspect to keep in view here is that if you have a 3-phase electrical connection, you will end up paying higher connection fees for it. In addition, you would have to pay fixed annual charges for 3-phase as well, so you shouldn’t be considering it for your new home unless it’s really needed.

Depending on the locality you live in, your property may also be connected to a SWER electrical line and many country areas have them. The SWER (single wire, earth return) delivers single-phase power. It is a very economical way of power distribution since it requires only a single transmission or active line. The earth is used as the return conductor and there is no neutral line.

In case you need to use any 3-phase motors in these settings, you would have to get a single-phase to 3-phase converter installed. Choosing the right phase is crucial to the optimal working of your equipment and for the safety of your property as well.

Ready.gov recommends that you keep an emergency kit in your car with a few essentials:

When branches become heavy with ice and fall on power lines, many are left without electricity and need to find alternate sources for keeping their home warm and safe.

If you live in the South, you know this: if it snows, you can pretty much count on school being cancelled. By about day three of last week’s #snowcation, videos started popping up in my news feed of kids dancing on kitchen tables and singing their 800th rendition of “Let It Go” while frazzled parents held onto their sanity. What’s a parent to do? The web is full of great ideas that creative parents have come up with, but here are a few of my favorites:

Growing up in North Carolina, the novelty of a real winter snowfall still catches me by surprise. By being as prepared as I can, I’m able to spend time enjoying the magic of winter with my family. How do you prepare for a winter storm? Do you have any creative ideas for keeping home-bound kiddos entertained?

As we near the end of summer, we’re still contending with temperatures in the 90 degree region. As a result, we are using our air conditioners for the majority of the day, every day. This puts a lot of strain on your electricity, which is probably reflected on your summertime utility bills. The good news is, there are a number of ways in which you can save energy, and thus reduce your electric bills. We’ve cited a few examples below.

This is a task that should be done at least on a yearly basis—bi-annually if you have a heat pump. You’ll hear some companies tell you that you can or should only have AC maintenance done before the cooling season begins. The truth is however, that AC maintenance can be done at any time of the year (though it is true that HVAC technicians are busier and harder to schedule at peak temperatures).

Preventive maintenance allows our technicians to fully inspect and clean your AC system, and make recommendations for any repairs that might be needed. When your system is effectively cleaned and repaired, it performs more efficiently, and therefor doesn’t use up as much energy as it normally would.

The Department of Energy estimates that 75% of the electrical use by your electronics occurs when those electronics are actually not in use. While there may only be a small amount of electricity used by each component, it adds up. We recommend that you plug each of your electronics into a power strip, and then when they aren’t in use, turn the power strip off.

This is a maintenance task that you can do on your own, at least every 3 months while your system is in use. If you have significant contaminants in your home, such as pet dander or cigarette smoke, then you should up this to once a month. If your air filters are clean, then your air conditioner won’t have to work as hard or run as long to do its job, which means it won’t be using up as much energy as usual.

Anyone who has ever tried to plug in an appliance only to find that it wouldn’t turn on is familiar with how frustrating electrical outlet wiring problems can be. The whole purpose of having outlets is the convenience, but that goes right out the window when they stop working without warning. Although a dead outlet might automatically seem like a big problem, sometimes it can be due to a simple issue. This isn’t always the case, of course — sometimes there will be electrical outlet wiring problems that can only be addressed by a professional, particularly when the issue is with your outlet’s wiring.

You might be able to save yourself a call to an electrician if your outlet problem is something easily fixed. You can even resolve some minor issues without the use of tools! If you know what steps to take, you may be able to figure out if the dead outlet is something you can remedy yourself. If you discover the problem is something that should be handled by a professional, don’t take any chances. Messing around with wiring can put you in danger and damage your electrical system instead of making the problem go away.

A simple issue can quickly turn into a very expensive one if you aren’t careful. Here are some easy things to try that won’t put you in any danger:

The electricity you use to power your home is most likely generated by burning coal, with some nuclear and natural gas-fueled current in the mix for good measure. However, that could all be changing, and faster than anyone expected. While renewable fuel sources like solar and wind power make up only a small part of the nation's electrical grid today, wind could actually be the leading source of electricity in little more than three decades.

Viable and Competitive

Wind could surpass other sources and provide as much as a third of the United States’ electricity by 2050, according to a report by the U.S. Department of Energy (DOE) Wind and Water Power Technologies office. Wind currently weighs in at only 4.5 percent of the supply, but if projections hold, that will increase to 10 percent by 2020 and 20 percent by 2030.

“The wind industry can be characterized by the substantial growth of domestic manufacturing and the level of wind deployment seen in recent years,” José Zayas, director of the DOE Wind and Water Power Technologies office, said to EcoWatch. “Wind power systems are now seen as a viable and competitive source of electricity across the nation. Wind power’s emerging role is an important option in a portfolio of new energy solutions for future generations.”

Benefits to Public Health, Environment

Should the prediction of wind's dominance come to pass, it would have numerous benefits for the environment and for consumers. Even at current levels, wind has reduced water consumption by 36.5 billion gallons and carbon emissions by 115,000,000 metric tons compared to traditional power sources, according to the government.

That means a lot less carbon getting released into the atmosphere, helping to slow our contribution to climate change. Plus, once the infrastructure is built, wind is free to harvest, and doesn't have the same environmental tradeoffs as coal and natural gas. The benefits “can address key societal challenges such as climate change, air quality and public health, and water scarcity,” the report said.

Uncertainties Looming

The rosy projection is just that. There are numerous uncertainties that could affect how well wind power actually does in the future, including government policies to incentivize wind or decentivize coal usage, the supply and price of natural gas, and the demand for electricity overall in the United States.

The technology around wind generation will have to hold its own as well. Growth in market share depends on continued advances in efficiency, more transmission capacity and better weather forecasting so we can best take advantage of favorable gusts.

Global Optimism

Should the growth of wind continue as predicted, there could be hope for a cleaner, healthier future. And what's good for the United States can be good for the rest of the world as well.

“The global energy market of the future is poised to be the largest market the world has ever known,” Secretary of State John Kerry said in a speech about wind power. “Pursuing cleaner, more efficient energy is actually the only way that nations around the world can build the kind of economies that are going to thrive for decades to come.
