The New Austrian Energy Group Open a Round of Smart New Energy Revolution
By Himfr Tian
From the Canadian (Mark Kerbel) simple electrical control systems to the U.S. “smart grid,” the introduction of creative energy in the future want to practice, technology and the concept of human development often unexpected dimensions. The Expo Hall, the new pan-Austrian group will bring its network of smart appearance and new energy concept has become the focus of public concern, the U.S. intelligence network stands in the eyes of the world is no longer thriving.
Chinese old saying of “proper way” in low-carbon action has been most vividly in the exhibition play. Here, visitors can see not only track the direction of light irradiation of sunflower-shaped solar panels, there is a full-scale “algae-to-liquid” device.
Perhaps you will be greatly surprised, eyes in a transparent, light green liquid pipeline can of carbon dioxide for food, after handling every level, the final conversion to biodiesel.This is China’s clean energy innovation from the company demonstrated the new Austrian technology group. Austrian group also adopted a new interactive touch screen display to visitors – the pan can network. Pan-network platform to reflect the energy of innovation, both to improve energy efficiency, reduce energy consumption, to achieve carbon dioxide emission reduction, or even “zero carbon.”
Proposed the concept of the current environment, China and the world’s energy situation is a “good medicine” These innovative new energy technologies will bring a new industry – smart new energy. So smart new energy is what? He is not an abstract concept, simply, is that the system energy efficiency technology and IT technology coupled to a smart new energy systems industry. Energy industry is to combine it with the IT industry to make a different energy to a unified platform on the basis of mutual transformation of people’s different needs and distribution.
In another way, smart new energy industry, renewable energy not only innovative, but also energy efficient and clean use of traditional, more importantly, to the intelligent management of energy resources in order to achieve more efficient use of energy, to carbon dioxide emission reduction. To put it simply, the future, “my home’s energy output my remote control”, to the high and low power consumption.
Some experts said in an interview, “energy intelligence to speed up the process, they are bound to be asked to intelligence operation between the various energy sources. Pan to network emerged in this context, it is the product of the times.”
Previously the industry has a perception that the financial crisis appears to be triggered by U.S. subprime mortgage crisis, there is also the deep reason technology. Imagine, if no new scientific and technological revolution (such as new energy, bio-technology, outer space, a breakthrough in the theory of relativity), the world economy will be slowing down.
Fourth scientific and technological revolution will also take full account of human factors, by the end of 2006, the U.S. “Time magazine” Person of the Year for 2006 was awarded the “YOU”, on behalf of the millions of individuals, declare the “era of individual consumption,” the advent of. The originator of Neurophysiology, Sir Charles Sherrington also believes that the fourth field of scientific and technological revolution the revolution must be conscious.
This can be attributed to pan to network tasks: the material into energy, then transformed by information systems to people’s everyday lives, this will be the initial stage of low-carbon society, it means to lead low-carbon technologies start to real change in the daily lives of ordinary people.

Climate change, energy saving light bulbs and the Daily Mail
The modern florescent lamp was first conceived by Peter Cooper Hewitt in the late 1890s and they were initially used for large industrial buildings and photographic studios.
This technology was later applied in the first commercially practical compact florescent light bulb (CFL) designed by George Inman and the General Electric Company. Although this development was designed over 70 years ago it was the forerunner to the modern CFL invented by Ed Hammer and General Electric in response to the 1973 oil crisis. Although a successful design, the invention wasn’t manufactured due to the expensive costs of production and the potential investment needed. The design was subsequently leaked and copied by other leading manufacturers leading to a gradual increase in usage and continued improvements.
Due to the rising cost of electricity in both the UK and the US many households and business, keen to reduce costs, have switched there lighting to CFL bulbs as they are on average 10 times more efficient. CFLs also help to reduce carbon emissions leading to a planned phase-out by the EU ensuring incandescent bulbs are no longer available by 2011. Despite the potential cost saving gained there remain staunch critics to CFL energy saving bulbs in the popular press. Much of this criticism involves popular myths associated with ‘energy savers’ that have long since been ironed out by manufacturers.
With headlines such as ‘Environmentally friendly light bulbs ‘can cause skin cancer’’ (2008) and ‘Revolt! Robbed of their right to buy traditional light bulbs’ (2009) the Daily Mail is leading the campaign against Energy Saving bulbs. Such reports have been slammed by the government and the Lighting Association as irresponsible ‘scare stories’ to sell newspapers and last year the Energy Saving Trust set out to convert the public by introducing the ‘Pepsi Challenge’. This survey, to study people’s reactions to energy saving bulbs, allowed people to enter two different rooms, one lit by energy savers and the other by traditional light bulbs. The study found that half the people could not tell the difference and additionally 2 out of 3 people preferred the energy saving ones.
Concerns over the mercury content of energy saving bulbs have also been one of the papers ‘buzz topics’. Realistically however most modern CFLs use amalgam, a mercury substitute that is completely safe to handle, transport and store and poses no direct risk to humans or the environment. Other bulbs use recycled mercury and their price included a recycling charge making them far more environmentally friendly than incandescent bulbs.
With climate change a continual threat to our way of life, is it irresponsible for the Daily Mail to wage war against energy saving products? The paper reported almost continually throughout the beginning of the recession on ‘money saving tips. There promotion earlier this year to distribute a free 100w bulb to every reader has been criticised by some environmental groups as ‘climate suicide’.
The paper tends to use outdated views of CFLs to convince its readership that they are being policed into buying something they don’t want. However, is it not true that in many aspects of our advanced capitalist society? Indeed wasn’t the UK’s newspaper media guilty of ‘barging out’ the smaller niche newspapers in order to create a greater market share (and limited consumer choice).
As paper news becomes ever more obsolete, newspapers need bigger gimmicks and more shocking headlines to shift units, this results in more questionable facts and more outlandish claims. I encourage anyone to seek a balanced view in the topic, and I am confident that reducing energy cost and carbon emissions is a good thing. I encourage you to take a look at Greenhouse Organisation should you require energy saving light bulbs.
Light Up Your Life With Energy Saving Light Bulbs
A compact fluorescent lamp (CFL), more commonly referred to as an energy saving light bulb (ESB) is a type of fluorescent lamp. The energy saving light bulb has been created to substitute for the standard incandescent lamp that many people still use. They fit into exactly the same standard light fixtures as incandescent light bulbs so you needn’t have to spend on new fittings to accommodate them.
Energy saving bulbs emit the same amount of visible light but use less power to do so, plus they have a longer rated life. While the purchase price is typically a more than that of an equivalent incandescent lamp, the extended lifetime and lower energy use will more than compensate for the higher initial cost. For example making the change in your home can save approximately twenty pounds in electricity costs over the course of a year. The average rated life of a these bulbs is up to 15 times more than that of an incandescent bulbs with a rated lifespan of between 6,000 and 15,000 hours, whereas incandescent lamps are usually expected to have a lifespan of 750 hours or 1,000 hours.
For a given light output, energy saving bulbs use 20-33 percent of the power of equivalent incandescent lamps. Around 10% of UK household carbon emissions come from light bulbs so the environmental benefit of these bulbs could be enormously significant.
Energy saving bulbs are produced for both alternating current (AC) and direct current (DC) input. DC energy saving bulbs are often used in recreational vehicles as well as in households. Interestingly, they can also be operated using solar powered street lights, using solar panels located on the top or sides of a pole and luminaries that are specially wired to use the lamps. This makes them an even more eco-friendly feature.
Although incandescent bulbs reach full brightness a fraction of a second after being switched on energy saving bulbs manufactured after 2009 also turn on within a second, but they do still take time to warm up to full brightness. Some energy saving bulbs are marketed as “instant on” and have no noticeable warm-up time scale, but others can take up to 60 seconds to reach full brightness or longer in very low temperatures.
It is important that we all play a part in trying to reduce our own carbon emissions. Every little bit we do, even if it’s as simple as changing a light bulb contributes towards slowing down global warming and protecting our future.
The Significant Energy And Cost Savings Of Micro CHP Systems
By Alan Jacobson
Micro CHP systems are an exciting home energy-producing technology currently used mostly in the UK and Europe. It is a popular and growing way to heat homes, and is seen as a way to meet progressive government objectives while saving the consumer money. It is likely that Micro CHP systems will also become more popular in the US soon because of their many benefits. In fact, given current oil and gas prices, there are currently companies studying the possibility of bringing this technology in a widespread way to the US.
CHP (combined heat and power) is an extremely efficient technology for generating electricity and heat simultaneously. This process is often referred to as “cogeneration”. Micro CHP systems can use a variety of generation technologies, including fuel cells, Stirling engines, or conventional means like gas and oil. Simply put, the heat generated in the process of creating electricity is recovered in a manner than allows it to be used to heat the home.
Micro CHP systems are very simple to install and can take the place of a conventional boiler or furnace. A micro CHP system can be as much as 90% energy efficient. Most who use domestic CHP report having a lower energy bill. In addition, in this age of Global Warming, micro CHP reduces the carbon “footprint” of homes that use it, reducing carbon dioxide emissions significantly.
One of the more exciting aspects of micro chp systems is their potential to allow people to actually sell the excess electricity produced when heating the home back to the electrical company – often called “on the grid” micro CHP. This could mean that you’d heat your house, and get a check from the electrical company!
MicroCHP is extremely easy to install. The challenge might be to find a qualified installer, particularly if you are in the United States. Some existing conventional systems can remain intact, with just retrofits and added parts installed. However others may need to be completely replaced. Depending on your current system, you should be able to recoup the cost of installation in anywhere from one to five years.
Recent predictions suggest that the use of “combined heat and power” (CHP) on a large scale by utilities could be a multi-billion dollar industry across the globe in just a few years. Many new houses are built with the systems installed, and the cost involved in adding micro CHP to existing homes is coming down dramatically. You could tap into this exciting new technology yourself for your own home, save money on your utility bills, and reduce your carbon “footprint” in the process.

A Brief History of Light Bulbs
By Rodney Munch
The along with the wheel, the light bulb is one of the worlds’ most important inventions and if you like seeing at night more than driving, then you will no doubt view the light bulb without question as THE most important.
The light bulb as we know it today is a product of the work of more than 10 notable inventors from Germany, the UK and the USA over a period of 182 years.
It all started with an English Chemist, Sir Humphry Davy in 1809 who noticed that by passing electricity from a battery though a carbon strip, it glowed. This was the making of the first arc lamp. Humphry died in 1829, around one hundred and twenty years before seeing the light bulbs he was so instrumental in inventing, light up the trenches of World War 2.
About 11 years after Davy, another English inventor, Warren De la Rue created a light tube by passing an electrical current though a platinum filament contained in an evacuated tube. While a successful model, this was highly impractical for widespread use due to the cost of the platinum filament.
In 1854, all hats in the light bulb community were off in the direction of Germany. Henricg Globel, who by profession was a watchmaker created the first true light bulb, using a carbonised bamboo filament placed in a glass bulb. The term ‘globe’ in ‘globe light bulbs’ could have possibly been named after Henricg, although I am not at liberty to say.
Another German, Herman Sprengel provided another breakthrough, inventing the mercury vacuum pump making a strong vacuum inside the bulb possible. This allows a longer life light bulb as it removes the effects of oxidation on the filament.
The most famous of all the inventors who had a hand in the development of the Light Bulb and often (wrongly) handed the crown of inventing the light bulb is the American inventor Thomas Alva Edison who went on to pioneer other notable inventions such as the phonograph and the kinetophone (talking motion picture). For involvement in the development of the light bulb he invented a carbon filament that burned for 40hrs which he put in an oxygen-less bulb. By 1880 he had managed to extend the life of his bulb to over 1200 hours using a bamboo derived filament.
Tungsten popped its head into the light bulb world in 1906 when the General Electric company of America patented their use. At the time however, these filaments were costly.
In 1910, an American Physicist by the name of William David Coolidge (or William to his friends) came up with an improved method of making the tungsten filaments. His improved method greatly extended the life of existing filaments and made them much more economical.
The light bulb as we know it was made and continues to light up the dark nights
In 1991 Phillips invented a light bulb capable of over 60,000 hours. That’s almost 7 full years of illumination. Even more if you switch it off when you go to bed.
