Easy Install Home Automation System Saves Energy
admin | May 18th, 2009

A TV automatically turns on the surround sound amplifier, a smart microwave oven downloads new cooking recipes, a thermostat automatically changes to its energy saving set point when the security system is enabled, bathroom floors and towel racks heat up when the bath runs, an email alert goes out when there is water in the basement. When did the Jetson-style home of the future become a reality? When products from INSTEON™ set the new technology standard for a new type of cost effective advanced home control.

They enable product developers, much like the iPhone has, to create these distinctive solutions for homeowners, and others yet unimagined, by delivering on the promise of a truly connected ‘smart home.’ They have cost-effective dual band network technology optimized for home management and control. Their  products can interact with one another, and with people, in new ways that will save energy while improving the comfort, safety, convenience and value of homes around the world.

Today’s homes are stuffed with high-tech appliances, entertainment gear, computers, and communications gadgets. Utilities, such as electricity, lighting, plumbing, heating and air conditioning are so much a part of modern life that they almost go unnoticed. But these systems and devices all act independently of each other however, there still is nothing that can link them all together. Houses don’t know that people live in them. Lights happily burn when no one needs them on, HVAC is insensitive to the location and comfort of people, pipes can burst without anyone being notified, and sprinklers dutifully water the lawn even while it’s raining.

For a collection of independent objects to behave with a unified purpose, the objects must be able to communicate with each other. When they do, new, oft times unpredictable properties can emerge. In biology, animals emerged when nervous systems evolved. The Internet emerged when telecommunications linked computers together. The global economy emerges from transactions involving a staggering amount of communication. But there is no such communicating infrastructure in our homes out of which we might expect new levels of comfort, safety, convenience and energy management to emerge.

There is nothing we use routinely in our homes that links our light switches or our door locks, for instance, to our PCs or our remote controls. It’s not that such systems don’t exist at all. Just as there were automobiles for decades before Henry Ford made cars available to everyone, there are now and have been for some time systems that can perform home automation tasks. On the high end, all kinds of customized systems are available for the affluent, just as the rich could buy a Stanley Steamer or a Hupmobile in the late 1800s. At the low end, X10 power line signaling technology has been around since the 1970s, but its early adoption is its limiting factor—it is too unreliable and inflexible to be useful as an infrastructure network.

The INSTEON family of products enables simple, low-cost devices to be networked together using the power line, radio frequency (RF), or both. All INSTEON devices are peers, meaning that any device can transmit, receive, or repeat other messages, without requiring a master controller or complex routing software. Adding more devices makes an INSTEON network more robust, by virtue of a simple protocol for communication retransmissions and retries.

Smart Energy
admin | April 28th, 2009

Utilities around the world are under pressure. Growing populations are using increasing amounts of power, which is putting a strain on existing supplies. In many countries (including the US), the increase in demand is growing faster than the rate at which utilities are able to increase their transmission capacity. And the cost of providing power is also increasing due to higher fuel costs and increases in the cost of construction and capital expenses.

To make things even more challenging, governments around the world are introducing new regulations and guidelines to reduce emissions. And many countries have deregulated the energy sector in recent years, which has led to greater competition along with consumer demand for more control over power usage and costs.

This has forced utilities to rethink tradition practices and look for a smarter way to provide supply, billing and services to their customers.


About Smart Energy

AMR, AMI and HANs

Automated meter reading (AMR) and advanced metering infrastructure (AMI) are revolutionizing the industry. AMR provides more efficient and timely metering information, while AMI uses this information to put more control into the hands of both utilities and consumers by giving them more detailed information about consumption. This allows utilities to better regulate supply and to refine their pricing structure based on demand cycles. It also gives consumers immediate feedback about their usage, allowing them to reduce consumption by turning off things they don’t need and switching others over to non-peak demand times when prices are lower.

Demand Response

Demand response (DR) refers to the reduction of consumer energy usage at times of peak usage to help address system reliability, reflect market conditions and pricing, and support infrastructure optimization or deferral. Demand response programs can include dynamic pricing/tariffs, price-responsive demand bidding, contractually obligated and voluntary curtailment, and direct load control/cycling.

In a DR system, AMI networks are extended through smart meters or separate gateways to also include home area networks (HANs), which connect communicating devices and systems such as lighting, thermostats, load switches, and in-home displays. Utilities who institute time-of-use pricing schemes can use the HAN to communicate the current price of energy to the consumer. Smart appliances connected to the HAN can be controlled automatically or manually (including remotely) to react to pricing events and operate during low-cost energy periods.

Utilities can also be given access to HANs in certain situations, for example, during emergencies they can adjust thermostats and other high-usage household applications to free up supply and make sure it can be delivered where it is most needed.

Applications

  • Utilities are able to track peak usage times (and days), which provides them with the ability to offer consumers a greater range of rates and programs, such as time-based pricing.
  • On-demand meter reading and remote troubleshooting allow utilities to provide better and more timely consumer support. Utilities have more information at hand about outages and restorations, and are able to provide consumers with reliable information about when power will be restored.
  • Smart energy can be integrated with smart homes to provide both consumers and utilities remote access to the home area network (HAN). For example, consumers can remotely adjust usage during peak periods when prices are high, and utilities can remotely adjust usage during emergencies.

Savings

  • Demand response can enable utilities to keep prices low by reducing demand when wholesale prices are high.
  • Utilities can post meter readings daily (or at more regular intervals) for consumers to view, which enables consumers to track and modify their energy usage. This provides more timely and immediate feedback than traditional monthly or quarterly statements.
  • Utilities can not only notify consumers of peak demand times, but also monitor the extent to which those notifications cause consumers to change their habits and reduce their load during these periods.
  • Utilities and consumers both benefit from more accurate billing that is available thanks to the increased granularity of usage information. This gives consumers better control of their usage and passes on the biggest savings to those who use services most efficiently. It also helps to reduce the number of billing inquiries and helps to make those inquiries easier to resolve.

Safety and Conservation

  • During emergencies, utilities can create “partial outages” in non-exempt buildings to ensure that power remains available where it is most needed. Partial outages are more economically efficient than full rotating outages because the effects are limited to the reduction of a single discretionary service (such as air conditioning) rather than the elimination of all services.
  • When consumers use less power to save money, utilities are better able to manage the power they have available and don’t need to generate as much. This not only reduces costs for the utility (in reducing the number of new power stations that need to be built), it also helps to reduce emissions to satisfy new “green” legislation.

Tips For Manufacturers To Go Green And $ave Green
admin | April 21st, 2009

As Earth Day Approaches, Siemens Identifies Top 5 Ways for Manufacturers to Drive Productivity & Energy Efficiency

ATLANTA — According to the U.S. Department of Energy, the industrial sector has long been the country’s largest energy user, currently representing more than one-third of the country’s total energy consumption. With this in mind, manufacturers across the United States must identify sustainable energy solutions that will drive efficiencies. As Earth Day approaches, there is no better time to seal in the savings on your facilities utility bills and begin working toward your sustainability targets.

Do you want to reduce the energy costs at your plant? Dennis Sadlowski, President and CEO of Siemens Energy & Automation, Inc., the U.S. industrial arm of German engineering giant, Siemens AG, recommends the following five easy tips for factory and manufacturing facility owners and operators to reduce their carbon footprint and start reaping the savings:

1.  Do Your Homework. First and foremost, you will not know how much you can save, until you know where the money is being spent. An Energy Audit will help you better understand your energy usage and determine where your facility can go green and save money. Siemens specialists will come to your facility to identify key energy saving areas for your facilities current and future needs.

2.  Rethink Your Lighting. By simply replacing your lighting with energy efficient products and controls, you can reduce energy consumption up to 50% as well as eliminate the risk of mercury contaminants in a very short period of time. Siemens offers a variety of lighting solutions and programs that lower utility bills and reduce air pollution.  Siemens also offers lighting controls that help reduce your energy consumption with smart schedules and automated control.

3.  Evaluate Your Motors & Drives. Electric motors are responsible for almost 70% of all energy consumed in industrial applications. This 70% holds a considerable saving potential that is just waiting to be realized. So why not start now by replace existing motors with energy efficient motors?  Or save even more by adding variable frequency drive systems to the motors. In some cases, drives can contribute a 30% energy savings with a seven month return on investment.

4.  Control Heating & Cooling Costs. As much as 30% of the energy used in your facility comes from heating and cooling costs. Making smart decisions about your facility’s heating, ventilating and air conditioning (HVAC) system can have a significant impact on your utility bills. Simply adding Siemens’ drive and control systems can reduce costs by as much as 25%.

5.  Monitor the Situation. By knowing and understanding their plants’ electrical footprint and monitoring energy use, companies can track their progress toward efficiency goals as well as establish benchmarks for achievement. With an Intelligent Energy Monitoring system from Siemens, you can keep track of energy usage across multiple locations from one central source to ensure maximum efficiency and control costs.

Technology breakthrough boosts solar power
admin | February 16th, 2009

freescale-pwr-conversion_lr1

Freescale Semiconductor on Monday is unveiling a new power conversion technology that the chipmaker says will dramatically enhance the efficiency of solar cells and other devices by allowing them to operate at low voltages.

That means a single solar cell attached to a mobile phone or other handheld device could charge the gadget. The bigger potential is to maximize the electricity generated from rooftop solar panels. which typically contain a dozen or more solar cells each. When a cloud or a tree shades part of a solar panel, power output from all the solar cells drops because they are linked together. By integrating Freescale’s power convertersamsung-blue-earth1 into each solar cell, those that aren’t shaded can still produce electricity, according to Arman Naghavi, general manager of Freesale’s Analog, Mixed-Signal & Power Division.

That’s because each solar cell can operate at much lower voltages when Freescale’s (FSL) converter is used. While most electronics need a jolt of 700 millivolts to begin working, Freescale’s technology allows them to operate on as little as 320 millivolts. (See video below.)

Sounds geeky but the consequences could be far-ranging, reducing electricity consumption and opening the door to a new generation of solar-powered devices.  One big hurdle to using solar cells to power everything from laptops to street lights is that it takes too many of them to produce enough power to be practicable. After all, who’s going to carry around a solar panel to charge their MacBook.

Freescale’s technology could change that equation. “For instance, you wouldn’t have to put a battery in a garage door opener – just add a solar strip on the remote control,” Kevin Parmenter, a Freescale applications engineering manager, told Green Wombat. (Samsung last week announced it would start selling a mobile phone (photo above) equipped with a solar panel but it’s unclear just how much talk or texting time it would allow.)

Other uses are more sci-fi: self-powered nanosensors that tap the technology to harvest ambient heat or friction in the environment.

The converter will hit the market in the second half of 2009. Potential customers include solar cell makers like SunPower (SPWRA) and Suntech (STP) as well as biomedical companies and defense contractors. Freescale, headquartered in Austin, Texas, was spun out of Motorola (MOT) in 2004.

“It really helps the entire green movement,” says Naghavi. “We are seeing a tremendous interest from lots of areas historically we have never touched or played in.”

Boosting Solar Power

Boosting Solar Cell Power

Solar Cell Power Scientists are continuously improving the existing solar cells. Now they are taking the help of computer simulations and real lab testing. A group of physicists and engineers at MIT have discovered new methods to make the existing solar cells more efficient by 50%. Currently the most efficient solar cell gives 45% output and is extremely expensive to produce. Cells produced by using this new technology will be more efficient and cost effective. Their cost effectiveness emerges from just 1% use of refined silicon. It should be noted that refined silicon is quite costly.

Cost Benefits:
Scientists want to bring clean and green energy on par with energy produced by fossil fuels. One of the biggest hurdles they face is cost. Most of the green energy is quite expensive and they have a longer break-even time. So here the MIT team has reduced the amount of extremely thin layer of silicon used in the solar cell. They are using hundreds of times less material.

Choosing Different but Simple Path:
The MIT team has paid close attention to the limiting factors of the solar cells. One of the greatest disadvantages in the existing solar cells is that whatever amount of light is falling on the solar cell has got very little time to be converted into energy. So this MIT team has concentrated its efforts on making the sunlight stay inside the cell for a longer duration of time therefore these cell can produce more energy. Peter Bermel, a postdoctoral researcher in MIT’s physics department and his team took the help of computer simulations and applied various advanced chip-manufacturing techniques.

They went for the anti-reflection coating to the front of the cell and a multi-layered reflective coating to the back of the silicon films which were ultra thin. In the end, the team settled for the best result in a multi-layered reflective coating coupled to a tightly spaced array of lines. This technique armed the cells like a laser around the cell, where light can bounce back and forth before finally exiting. This way the light stays longer inside the cell and can produce more energy. Current solar cells don’t have these coatings so the light is just reflected back to the surrounding air in the atmosphere.

“It’s critical to ensure that any light that enters the layer travels through a long path in the silicon,” Bermel said. “The issue is how far does light have to travel [in the silicon] before there’s a high probability of being absorbed” and knocking loose electrons to produce an electric current.

Trying out various combinations by computer simulations
When you have to try out various combinations and don’t know which combination will yield that magical results, its best to try out computer simulations. They will give out the excellent and almost correct results and save the time and material costs. The MIT team ran thousands of simulations with each one designed to try a slightly different approach toward keeping photons within the cell for longer. Using computer simulations they will be able to find the magical combination of multi-layered reflective coating coupled to a tightly spaced array of lines. This approach enhances the energy output of the cells by as much as 50%.

Examining the Correct combination in Laboratory
When this research team thought that they have found the right combination in the computer simulation they verified the results in the laboratory. These tests were carried out by the graduate student Lirong Zeng, in the Department of Materials Science and Engineering. According to Lionel Kimerling, who directed the project, “The experiments confirmed the predictions, and the results have drawn considerable industry interest.”

This project has caught the attention of like-minded people. Stephen Saylor, CEO of SiOnyx in Beverly, MA says, “This work demonstrates the importance of improving the performance of thin-film technologies. “SiOnyx is engaged in increasing the absorption of red and infrared light in thin silicon devices.

Bermel says that his team is already thinking of other production methods. One sound option is nanoimprint lithography, but they haven’t tried it yet. “A 35 percent efficiency increase is clearly predicted in simulations,” he opines, “but the challenge is, ‘Can you make it practically?’ That’s what we’re working on.”

Introduction
admin | December 22nd, 2008

Welcome to The Energy Spot.

We will introduce new products and ways on how to conserve energy, how to save money, introduce new products, education, careers, current policy and add general energy commentary from time to time. Our goal is to filter through the energy noise being created out there to bring you the cream of what we deem to be worthy of a look or your time to read.

Energy saving tip of the day:

Water Heater

Your homes water heater accounts for up to 14% of your total home energy cost (gas, propane or electric). Most heaters are kept at 180 degrees F when they do not have to be. It can easily be turned down to 120 degrees F with without sacrificing anything except paying more money to your local utility!

If you are in the shower and have to mix in cold water your heater is too high. Almost all Dishwashers preheat the water these days so having it at 180 degrees F is not necessary. And as for washing your clothes… they really get just as clean in cold/warm water as they do in really hot water. Also most water heaters have a little red dial on them near the base. If you are going to be away for awhile it makes sense to turn that red dial to the left until the arrow shows it on the “vacation” area of the dial. Why heat water when you are away. This tip will save you money immediately as well as conserve energy and give you a great feeling that you are doing your part to be green.

Remember GREEN = GOLD!!
