Everyone likes to save energy, right? You’re reducing your impact on the environment and saving money on utility bills at the same time – talk about a win-win scenario. However, despite the obvious benefits, the percentage of Americans who take energy efficiency steps in their lives is actually dropping, according to a recent poll. Read on to find out more.

Commitment to Energy-Saving Decisions

The survey, conducted by the Harris Poll, did contain some good news. A relatively high percentage of respondents take some actions to reduce their energy use – 75 percent of people, for example, said that they turn off lights and televisions when they aren't being used. That's a good first step. However, last year the number was 79 percent, and it reached as high as 82 percent in 2012. What gives?

One explanation is that money talks. Natural gas and oil prices have been relatively low in recent years, so people just might not be paying attention to every last megawatt.

"Even though understanding of energy sources remains at historical levels, in the last few years fewer consumers are taking steps to reduce energy consumption in their homes," Carol M. Gstalder, Reputation & Public Relations Practice Leader for Harris Poll, said in a press release. "As energy prices drop, so do consumers' commitment to energy-saving decisions from replacing light bulbs and water heaters to installing solar."

Lax Attention Across the Board

The Harris Poll laid out other areas where the survey found a reduction in consumer efficiency strategies:

Renewable Fuels Popular, Coal Not so Much

Taking another tack, Americans have some strong opinions about what types of fuels are best to keep feeding our energy addiction. Renewables are popular, with 78 and 75 percent of respondents saying that the benefits of solar and wind, respectively, outweigh the costs.

Getting the short end of the opinion stick were nuclear energy and coal. About 42 percent of respondents thought the risks outweighed the benefits for nuclear, with only 34 percent responding positively. And 46 percent of people gave a thumbs-down to coal, with 34 percent still in favor.

How You Can Do Better

If you want to uncover more ways to save energy in your home, have a home services technician conduct an energy audit to discover any waste and inefficiencies. You'll be in a knowledgeable minority: Only 11 percent of Americans have had an energy audit, the poll found.

Mechatronics, or mechatronic engineering combines mechanical and electrical engineering to design innovative products and systems. These systems must rely on mechanical and electrical components working together in harmony.

The list includes DVD disc drives, anti-lock braking systems, manufacturing, electric motors and clothes dryers, among others. These devices require electronic controls and feedback systems to interact seamlessly with their mechanical design.

Motor control systems operate by using a programmable logic controller or PLC. This system allows advanced programming and algorithms to dictate a motor’s behavior. Therefore, they can be programmed to control multiple motors or VFDs. A robotic arm or a large factory machine is a good example of this.

In addition, PLCs can accept inputs from a wide range of sensors and switches. This allows precise feedback from the machine it controls. Furthermore, it executes built-in software.

The smallest high-precision motors, DC motors, found in computer hard drives and DVD readers. Due to their miniaturization, they can be easily controlled by computer software to perform nearly any imaginable task. A battery powered quad-rotor drone offers us a prime example of DC motor control. Accelerometers and gyroscopes feeding data into a computer controller adjust the speed of each motor independently to keep the drone flying level.

A simple technology that combines electric motors with feedback control, known as servomechanisms, provides valuable information. They utilize a small electric motor, gearboxes, and a potentiometer to produce accurate position feedback to the motor itself. This ensures that the motor has moved to the correct position. Thus, precise movement control of a motor is possible. Applications of servos include RC car steering, fly-by-wire systems in aircraft, robotics, and industrial control valves.

Servos communicate with computer systems, allowing them to be part of larger mechatronic systems, so they can be controlled by PLCs and computer algorithms.

The field of mechatronics constantly evolves. Therefore, as it does, it incorporates cutting edge computer software and mechanical design, bringing to life new inventions. These breakthroughs make modern-day living much easier and more fun.

Kauai’s electrical grid surges affect the life span of our computers, appliances, and other electronic equipment. Power surges can also completely roast the internal electronic parts during a storm or utility fault.

A whole house surge protector installed by a licensed electrician will greatly decrease the risk of power surge destruction.

Guarding against surges requires a two-pronged approach: a whole-house suppressor to tame the big, dangerous power spikes and an individual circuit (or “plug-in”) surge suppressor for vulnerable appliances and electronic devices. Both types essentially act like pressure-relief valves. Normally they just sit there, allowing electric current to flow through them. But with higher-than-normal voltage, the devices instantly divert excess voltage to the ground wire. (The best ones react in less than a nanosecond.) As soon as voltage levels return to normal, the flow of electricity is restored, unless the surge was big enough to melt the fuse built into some units.

Typically, whole-house suppressors are hard-wired to the service panel, a process that takes a licensed electrician about two hours. Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit. Protection for an average house with 200-amp service will run about $500 — including a couple of hours of an electrician’s labor. Separate but smaller whole-house units are recommended for the phone and cable lines. These protect fax and answering machines, televisions, and modems.

By themselves, whole-house suppressors can’t stop surges completely; up to 15 percent of excess voltage may leak by. That’s where “plug-in” surge protectors come in. These buffers between individual appliances and wall outlets come in a bewildering array of options and prices. They range from $70 units not much bigger than a computer mouse to $350 units the size of a pizza box that guard all the components in a home theater. But most plug-in models fall into three basic categories: the familiar multi-outlet power strip; the multitasking surge station that can handle phone and cable jacks as well as power cords; and the UPS (uninterruptible power supply), which completely cleanses electric power of random fluctuations and provides a short-term battery backup in case the power dips or goes out entirely. Expect to pay between $20 and $70 for a quality power strip or surge station, and from $100 to $250 for a UPS.
