Maybe you have never heard of electrical preventative maintenance or maybe you have but decided that you had no need for it. Many people ask if preventative maintenance for your commercial building is important—the answer is yes. The electrical system in your property is the most essential system throughout your building. Not only do the electrical systems in your building provide lighting for employees and clients, but they also play in an essential role in day-to-day operations—supplying power to almost every essential electrical device your business depends on.

Homeowners are always looking for ways to  lower their energy costs, and we can’t really blame them for wanting to do so. There are so many ways to go about conserving energy – both large and small – and we’re here to help you with some  ideas. It’s important to remember that even small changes can go a long way, so if you’re on a budget, don’t worry. Not every change requires a green gadget or a pocket full of cash. Simply altering a routine can have a serious impact on your annual energy costs.

We know that this can be a daunting process, because the opportunities are endless! This is why we’ve compiled five simple ways to lower energy costs.

The controller keeps on monitoring the application requirement in a continuous control loop. It then commands the inverter to produce the required voltage and frequency to meet the application requirements. To do this, the controller, comprised of a microprocessor, takes the input signal from the sensor and compares this with a reference signal. It then generates the appropriate control signal for the inverter to vary its output power.

In a typical application, the controller will monitor process parameters such as pressure, flow rate, temperature or liquid level. For example, an oxygen sensor in a boiler provides a signal to adjust the speed of the fan and control the amount of oxygen in the boiler system.

Today’s drives, using microprocessors, semiconductor power switches, and SMDs are now smaller, compact, cheaper, more reliable and efficient. A typical drive will also include a filter to suppress harmonics generated when converting the DC to AC voltage.

Citing the 98% school-to-work success rate at Thaddeus Stevens College of Technology, State Representative Jerry Knowles in Pennsylvania pushed his fellow legislators this week to consider a funding package to support additional trade and technical schools. Across the country and to the North, Governor Sean Parnell addressed the need for more programs in technical training, to create skilled electricians and plumbers in Alaska, to keep students in-state and create hirable graduates.

These states are the latest to join Ohio, Georgia and even the National government in their efforts to increase funding to vocational education programs. Many legislators point to the need for skilled workers in the labor market and hope to increase access to the training and technical education.

States are also hoping to increase funding to legitimize technical schools as well, eliminating for-profit institutions that are in the business of making money. They want to make sure electricians, plumbers, and other technical workers can graduate with reputable education and experience.

With unemployment among graduates of traditional education so high, the value given to a Bachelors over a technical program is being questioned by educators and legislators. Students of technical programs face a different employment future. The fields are highly recruited and sometimes offer apprenticeships as part of training. Moreover, the last of those trained in the last push for vocational education decades ago are retiring, and there is a large opening for professionals who have trained through technical schools.

Take for instance, electrical workers and engineers. The number of electricians set to retire in the next ten years will greatly improve employment opportunities for new graduates of technical programs. Additionally, when the population increases and more construction occurs to accommodate that population, more electricians are needed in the market. States are seeking to ensure that they have trained electricians, as well as engineers, surveyors and construction professionals, to fulfill that growing demand.

I grew up in the 90’s, back when thrift store shopping was considered alternative and grunge.  While I tooled around Goodwill listening to Nine Inch Nails on my Walkman, my more sophisticated friends were at the mall, looking adorable & stylish in the latest trend from The Limited.

But that was the 90’s.

Thrift-store shopping, dumpster-diving, and hand-me downs deliver a new parlance that has clever DIY’ers quaking with excitement for Saturday yard sales and obsessively scouring Craigslist for the Next Big Find.  This elegant new term for taking used items and making them new = REPURPOSING.

Also commonly referred to as recycling, upcycling, reinventing, revitalizing and/or reusing, entire boards are dedicated to this subject on Pinterest. Everything – and I mean everything – can be repurposed.  So why not the light bulb?

With a few basic tools and a steady hand, a light bulb can be hollowed out and transformed into a unique gift or decorative project.  Prepping the bulb, however, is not a task that we recommend for the kids.  Before you undertake any of these projects, take a moment to read a tutorial on how to safely hollow out a light bulb.
