Energy-efficiency Electronics Hardware A bridge Fuel To The Future

Demand for energy continues to be a major topic around the world. Renewable energy sources such as wind, solar or hydro power are increasingly being utilized to provide for that demand. Many States have even recently passed laws raising the minimum renewable usage cap that utility companies must implement into their overall supply. But … we still require escalating amounts of energy for agriculture, industry, and to heat our homes and offices. Emerging as a “bridge fuel” to clean energy and renewable resources, the power electronics industry is poised to span that gap with hardware solutions needed to build intelligent power systems.

The Obama administration plans to spend billions of dollars on power conservation and sustainable energy projects as part of a $787 billion stimulus package which is has focused on energy efficiency. Andrew Fanara, of U.S. Environmental Protection Agency’s Energy Star program has famously said. “Energy efficiency is the bridge fuel we must build on and must invest in” he stresses “Energy efficiency is the cheapest, cleanest, fastest way to act.”

In part, the administration’s strategy is to use improved energy efficiency as a method of buying time to invest in and explore emerging and clean energy options. With initiatives like the smart power grid gaining traction, the power electronics hardware that makes it all work and its new designs aimed at increasing energy efficiency will be at the core of the plan.

Already, there is huge demand for power efficiency by consumers found an industry survey. And, consumers are willingly paying a premium for electronic hardware that delivers energy efficiency. This trend anticipates a growing number of electronic hardware devices will be utilized, which lowers costs and drives improved energy efficiency. Measured in dollars per watt this high volume of hardware deployment forecasts the efficiency for power electronics may drop to as low as 12 cents per watt by 2013.

The focal point of “smart power” systems and a national smart energy grid has clearly been on the hardware side of the equation. To be successful, in the not to distant future, engineers will also make use of the intelligence provided by software so that the hardware components communicate most effectively to accomplish maximum reduction of power consumption. The know-how exists now for this integrated software, but it is still far from widespread.

Power Profiling is a valuable energy-efficiency tool that granularly identifies the power consumed specifically by HVAC, appliances, networks, lighting etc. and communicates this information to users. A user profile is developed by use of proprietary algorithms that calculate information regarding a structure’s overall usage, and several data points such as the time of day and its energy consumption history.

The purpose of power profiling is to enable users to know exactly what activities or systems are consuming the most power, including how much, and how that consumption is affected by actions they take. Most HVAC and appliances are not yet enabled so numerous hardware metering devices are used throughout the structure, at least an adequate number to demonstrate to the user what the largest power users are and how to limit consumption.

Home Area Networks (HAN) are increasingly communicating with utilities in addition to the traditional media centers and computers. Both utilities and consumer electronics companies are offering and assortment of hardware solutions with methods of pre-programming and remotely controlling home systems such as water usage, heating & cooling, and appliances. With the arrival of “smart” appliances and new wireless network protocols designed specifically for energy-efficiency, many of these hardware solutions communicate to users and utilities over one or more wireless systems.

ZWave for media and home automation

ZigBee chosen by utility companies because of it’s secure protocol, and

EnOcean a European self-powered energy harvesting technology that powers devices without the use of batteries.

Hardware using these wireless protocols can all be controlled from a single point building management system, or a homeowner’s computer. Even though these technologies are still on the leading edge, trends indicates they are very near to wide-scale adoption, enabling buildings to connect to smart grid applications that exponentially increase energy-efficiency.

Advances in alternative energy sources have provided greener ways of producing electricity and the burgeoning energy-efficiency industry is providing a plethora of energy saving hardware devices to help users re-tool . We can reduce energy consumption with these advances and make strides toward energy independence. Consider what T. Boone Pickens says “In additional to putting our security in the hands of potentially unfriendly and unstable foreign nations, we spent $475 billion on foreign oil in 2008 alone. That’s money taken out of our economy and sent to foreign nations, and it will continue to drain the life from our economy for as long as we fail to stop the bleeding.

Projected over the next 10 years the cost will be $10 trillion – it will be the greatest transfer of wealth in the history of mankind.”

“By investing in renewable energy and conservation, we can create millions of new jobs. Developing new alternative energies while utilizing natural gas for transportation and energy generation; securing our economy by reducing our dependence on foreign oil, and keeping more money at home to pay for the whole thing.”

Moving forward with renewables is a must, but it is also a documented fact that this increased capacity will not be enough to meet upcoming demands and provide energy independence. The tremendous strides being made in energy efficiency technologies are to help stem the tide, bridging the gap.

Extended Warranties for Electronics – Are they worth it

One of the primary concerns of consumers when buying an electronics product or device is the warranty offered by the company. Many countries have certain laws on the warranty of electronic devices due to the fact that these products are often highly indispensable to daily life. Despite the assurance that companies give regarding the standards of their products, a warranty usually gives more assurance to customers when purchasing a particular electronics product. In most cases, companies offer a one-year warranty for their products, while other companies may offer a limited warranty for the same amount of time. A limited warranty usually only covers parts or labor on a repair, but not both. Nowadays, companies are also offering extended warranties for their products.

The basic principle behind extended warranties is that it stretches out the usual one year warranty to two, three or even as much as five years. Of course, you usually have to pay a premium for a longer warranty, sometimes hundreds of dollars, depending on the product. So, are extended warranties worth it? The answer here primarily relies on what kind of electronics you are dealing with. If youre going to buy a very expensive device that is intended to be used on a daily basis and for a long period of time like LCD televisions, refrigerators or air conditioning units, then an extended warranty would be a good deal. On the other hand, if you intend to buy a laptop, which depreciates fast and becomes obsolete quickly, then a one-year or two-year warranty will usually suffice. However, the more you use a product, and the longer term you are going to use a product, the likelihood increases whether an extended warranty is a good value.

Aside from the type of electronics that you intend to buy, the warranty also relies on you as a user. If you know yourself as someone who is very careful in handling electronics, then you might be content with the bundled one-year warranty. However, if you tend to be harsh on your products, like putting them in your pocket or dropping them often, then you should opt to have an extended warranty.

Another useful tip for deciding whether a warranty is worth it for you, is to read up on reviews of the product first. Many times, the reviewers will talk about the warranty and what the best term is for the product. Consumer Reports actually offers reliability ratings for many products, and these can be of great help. If a product is listed as very reliable, then you may not need an extended warranty at all.

About the personal computers, iPod got a better rank as they brought out the product which doesnt contain the most harmful or toxic substances. And then HP followed.

SAMSUNG, DELL, LENOVO AND LG lost points due to the fact that harmful and toxic substances havent been removed. Most of the companies appeared on the Green Peace List have ever promised to remove all the PVC and BFRs in products by the end of 2009. In fact, 2010 American International Consumer Electronics Exhibition should have turned to be a green and non-toxic electronics session. However, its a great pity that most of the companies havent kept their promises. Then they put off the date to remove the harmful and toxic substances to 2011 or even some sort of longer.

According to the rank list, iPod did a good job, and HP follows. Except them, it seems that the rest companies took little actions in the work. Thats to say, both the environment and consumers are still suffering from the loss to a great extent.

This time NOKIA topped on the list with 7.3 points. Sony Ericsson, the only one which got the full marks rank to the second place. The third place was taken by Toshiba, but next time they will lose if they cant keep the promise to remove all the PVC and BFRs among the consumer electronics before April, 1, 2010. Additionally, PHILLIPS took the fourth place, and iPod ranked fifth from ninth.

HP ranked 11 from 14 due to their great efforts on power policy and power saving. Lenovo kept getting the 2.5 points as a result that they didnt finish the task in time and ranked sixteenth. SAMSUNG fell to 7th from 2nd because of the failure of removing the BFRs. SAMSUNG only managed to make the mobiles out of harmful substances, and put off the date of laptops to January, 2011, there even no exact answer about the TV and household electronics. Finally, the last one is still Nintendo.

SONY won extra points as they decreased 17% emission of the greenhouse gases between 2000 and 2008. Whats more, the ratio of using recyclable resources increased from 2.5% a year ago to 8%.

Each year about 17 thousand tons of recyclable polythene was utilized in many kinds of products. Its equal to 10% of the all used polythene in 2008. And 90% of the recyclable polythene is for the second time.

Among the 18 main manufacturers and consumer electronics factories, Microsoft and Nintendo still ranked at the end of the list. Many companies lost points because they failed to avoid using toxic substances. And rank changes took place along with it. In 2010, we should note that the personal computer and TV made great progress on the market. Any enterprises failed to reach the goal are in a kind of fight with “green idea”.

Introduction to Silicon Wafers used in Electronics

Silicon wafers are actually semiconductor devices that are heavily used in todays electronics. To some, these micro devices may seem dismissible but they really have important uses in technology. Silicon wafers are primarily used in manufacturing computer chips. Every electronic device that you enjoy these days contains these tiny yet very significant wafers.
