LED Lighting: An Illuminating Investment

19 Feb

LED Lighting: An Illuminating Investment

When considering LED lighting solutions for jewelry display cases, art gallery lighting or even museum displays, people love the way high-quality LED lights look, as well as their ecological benefits—but they may be put off by the higher initial cost.

The truth is that LED lighting is a money-saving investment over time. By installing LED lighting in display cases, on countertops and as overhead lights, you’ll save money over the next several years:

LED Lighting Lasts Longer
LED lamps last much longer than traditional lighting bulbs. In fact, they have an extra-long life of over 30,000-40,000 continuous hours—that’s about 6-8 years under normal usage conditions! You save big by not having to replace bulbs or lamps as often.

LED Lighting is Cooler
LED lights give off virtually no heat—which means you spend less on air conditioning to keep your store cool.

LED Lighting Uses Less Electricity
LED lighting solutions use just 3% of the electricity of regular halogen bulbs—just 3%! Imagine the difference that would make on your utility bill for running a store full of LED lights compared to your traditional lighting methods.

So don’t put off investing in LED lights. They show off your merchandise with true white, natural daylight-quality light. And their money saving benefits will more than pay off in the long run!

 

Environmental Positive Aspects Of Choosing LED Lighting At Your House

26 Nov

We all are challenged to do our role to save energy. By making little changes in how we live, we can start to make an impact on our world. One small change we all can make is to change our home and outdoor light fittings to LED light . There are numerous options for LED home lights and LED camping and hunting outdoor equipment on the market, all of which provide the energy efficiency advantages in LED products. The advantages can become evident quickly as we start to see our energy bill costs reduce for a couple of months.
For LED home lighting, there are many options available other than just bulbs. You can find LED light fixtures for your home, indoor and out, which will provide low energy, environmentally-friendly lighting that can save you money on your electrical bill.
If every single home in the United States were to change to LED home lighting, 90 power plants can be retired, a potentially powerful impact to the long-term health of the environment. Being energy-efficient and environmentally conscious doesn’t have to disrupt your entire life. The switch is as difficult as changing one light bulb in your house, the results of which would help you save money on your electricity bill every month. Just one home lighting fixture, one light bulb can be a positive step forward for your household. Take a look around your home and count the number of bulbs you use and look at how often you change them. Say, for instance that you change a bulb every two months. Now, consider that by changing them all to LED lighting for your house, you could leave them without needing to change them for 20 months. The slightly higher upfront costs of LED lights seem sensible.
By using lower energy LED home lighting in your home, even one bulb could keep one half of a ton of carbon dioxide out of the atmosphere throughout the life of the bulb instead of using incandescent light bulbs. Switching also keeps sulfur oxide and nuclear waste from the environment as well, leading to a cleaner world and one that will last much longer. By switching, our environment could easily rejuvenate itself without struggling with the excess carbon dioxide, sulfur oxide and nuclear waste emissions that are being released into the atmosphere each day. Even changing one lonely bulb in every house to LED home lighting would make a significant influence on the environment.
LED lights are less costly to function, but are a little more costly to buy.LED home lighting needs just one third of the energy that an incandescent light will use. A single 18-watt LED light can easily replace a 75-watt incandescent and in the life of the LED light, will save 570 kWh of electricity. With a basic 8 cents per kilowatt rate, that amounts to $45 dollars in electricity bill savings.
LED lights certainly are a wonderful innovation which has transformed the way the world is lighted. Not only are they durable, they have several environmental advantages. LED lights are five times more efficient than the usual normal incandescent light bulb and they last ten times as long. LED lights also use between 50 and 80 percent less energy compared to an incandescent light.

 

Reducing CO2 Emissions at Home

20 Aug

Climate change can be attributed to several factors associated to human activity. The most important among these factors are CO2 emissions. As households have the largest share among CO2 emissions, the EU-funded research project AIM is focusing on ways for increasing energy efficiency in the home.

Governments around the globe have taken actions for reducing CO2 emissions, as they have recognized the fast-changing pace of climate change and its devastating effects for our lives. The need of industrialized countries to minimise CO2 emissions has led to worldwide discussion in the context of the The Kyoto protocol about applicable strategies for control and real-time management of CO2 emissions. As statistics show (see figure 1), CO2 emissions differ by sectoral activities.


Figure 1: Annual CO2 emissions by sector (source: Climate Change 2001: Working Group I: The Scientific Basis)

The residential area accounts for the the largest part of CO2 emissions, considering that about 35 percent of the energy production of power stations is consumed by households. This leads us to the question, how effective existing CO2 control mechanisms are for households.

Massive installation of smart metering devices could solve the problem of energy metering, and thus address the issue of calculating CO2 emissions, but at the expense of extra energy. The alternative: recently emerged technologies enable the automated calibration of energy consumption on the basis of user-configurable thresholds.

The AIM approach

Looking at the energy control problem from a different perspective, the AIM project positions the user in the centre of energy management mechanisms. The main objectives of AIM in this respect are to develop management mechanisms for ultra-low energy consumption and to establish a user-centric approach in energy management that is based on the concept of “user programmes”. With this approach, AIM will create awareness among people on the environmental impact of the use of household appliances. Understanding how much energy an appliance consumes, gives users an active role in the fight against global warming by reducing power usage in the household.

As an alternative to approaches based on an energy metering architecture, AIM has developed a profiling technology that allows determining the energy consumption of household appliances via user programmes. Thus, even inexperienced users will be better able to realise how much energy is spent, when an appliance is switched on or is left in standby mode.

In comparison to existing energy saving solutions, the AIM system does not require extra components and exploits any home network infrastructure for the exchange of status and control messages between the central monitoring mechanism and the appliances (see figure 2).

At the core of the AIM concept is the Energy Monitoring Device (EMD), which is based on the concept of message exchange in the implementation of energy control applications. For households equipped with networked appliances, EMD is a slim software entity hosted on the residential gateway that “talks” to the respective appliance whenever the predefined energy consumption level is exceeded.


Figure 2: AIM concept and outline of network architecture

AIM’s real-time energy monitoring implementation does not require smart metering devices, as the network “understands” the appliance programmes and calculates on the fly the total energy consumption levels, using the corresponding energy profiles.

Extending its concept to the whole value chain of energy generation, supply and use, the AIM solution will also stimulate wider solutions for applying energy control in order to increase user awareness on other critical environmental aspects, such as the preference of renewable energy sources and rationalised energy usage around the clock.

The AIM solution is currently in the implementation phase, promising 20 percent of energy saving for active devices and close to 100 percent energy saving for devices in stand-by mode.

What Is A Carbon Footprint – Definition

13 Aug

A carbon footprint is defined as:

The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).

In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. (CO2 is the chemical symbol for carbon dioxide). When you heat your house with oil, gas or coal, then you also generate CO2. Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods also emitted some quantities of CO2.

Your carbon footprint is the sum of all emissions of CO2 (carbon dioxide), which were induced by your activities in a given time frame. Usually a carbon footprint is calculated for the time period of a year. The best way is to calculate the carbon dioxide emissions based on the fuel consumption. In the next step you can add the CO2 emission to your carbon footprint. Below is a table for the most common used fuels:

Examples:

For each (UK-) gallon of petrol fuel consumed, 10.4 kg carbon dioxide (CO2) is emitted.
For each (US-) gallon of gasoline fuel consumed, 8.7 kg carbon dioxide (CO2) is emitted.
If your car consumes 7.5 liter diesel per 100 km, then a drive of 300 km distance consumes 3 x 7.5 = 22.5 liter diesel, which adds 22.5 x 2.7 kg = 60.75 kg CO2 to your personal carbon footprint.

fuel type unit CO2 emitted per unit
Petrol 1 gallon (UK) 10.4 kg
Petrol 1 liter 2.3 kg
Gasoline 1 gallon (USA) 8.7 kg
Gasoline 1 liter 2.3 kg
Diesel 1 gallon (UK) 12.2 kg
Diesel 1 gallon (USA) 9.95 kg
Diesel 1 liter 2.7 kg
Oil (heating) 1 gallon (UK) 13.6 kg
Oil (heating) 1 gallon (USA) 11.26 kg
Oil (heating) 1 liter 3 k

Each of the following activities add 1 kg of CO2 to your personal carbon footprint:

Travel by public transportation (train or bus) a distance of 10 to 12 km (6.5 to 7 miles)
Drive with your car a distance of 6 km or 3.75 miles (assuming 7.3 litres petrol per 100 km or 39 mpg)
Fly with a plane a distance of 2.2 km or 1.375 miles.
Operate your computer for 32 hours (60 Watt consumption assumed)
Production of 5 plastic bags
Production of 2 plastic bottles
Production of 1/3 of an American cheeseburger (yes, the production of each cheeseburger emits 3.1 kg of CO2!)

To calculate the above contributions to the carbon footprint, the current UK mix for electricity and trains was taken into account.

Carbon dioxide is a so called greenhouse gas causing global warming. Other greenhouse gases which might be emitted as a result of your activities are e.g. methane and ozone. These greenhouse gases are normally also taken into account for the carbon footprint. They are converted into the amount of CO2 that would cause the same effects on global warming (this is called equivalent CO2 amount).

Few people express their carbon footprint in kg carbon rather than kg carbon dioxide. You can always convert kg carbon dioxide in kg carbon by multiplying with a factor 0.27 (1′000 kg CO2 equals 270 kg carbon).

The carbon footprint is a very powerful tool to understand the impact of personal behavior on global warming. Most people are shocked when they see the amount of CO2 their activities create! If you personally want to contribute to stop global warming, the calculation and constant monitoring of your personal carbon footprint is essential.

 

Low-carbon Life

02 Aug

“Low-carbon life” (low-carbonlife), refers to a lifestyle of the energy consumed when to try to reduce, thereby reducing the carbon, especially carbon dioxide emissions, thereby reducing air pollution, reduce ecological degradation, mainly from energy-saving solar terms and recovery of the three links to change the details of life.

Concept

The so-called “low-carbon life (low-carbon life)”, refers to a lifestyle of consumption during the reduction of the energy to try to reduce carbon dioxide life posters carbon emissions. Low-carbon life, for those of us ordinary people is an attitude, with everyone you would be willing to create low-carbon life issues. We should actively promote and to low carbon living, pay attention to four sections: power-saving, water saving, fuel-efficient, solar terms, starting from the bit. In addition to tree planting, also bought a very short distance transport of goods, it was the stairs, all kinds, some very interesting, and some inevitably some trouble. However, people concerned about global warming, reduce carbon dioxide confused real life into the area.

Towards low-carbon way of life and one of the ways is to quit the high cost of energy consumption of “convenience consumption” hobby. “Convenience” is the marketing and consumption of modern business life, popular values. Many people inadvertently facilitate the consumption in the huge waste in energy. For example, according to refrigeration technology experts estimate 70% of power consumption for the supermarket freezer, and open-type freezer glass door freezer electricity consumption higher than 20%. This projection, a medium-sized supermarket open type freezer for over a year about 4.8 million kWh of electricity consumption, equivalent to more consumption of about 19 tonne, more than about 48 tons of carbon dioxide emissions, more water consumption of about 190,000 liters. About Shanghai nearly 800 large and medium supermarkets, convenience stores, supermarkets, 6000. If widely adopted and medium-sized supermarket freezers glass door, the customer shopping just little things, saving about 45.21 million a year degrees, equivalent to savings of about 18,000 tons of standard coal, about 4.5 tons of carbon dioxide emissions. In China, per capita CO2 emissions of 2.7 tons, but only 40 of a city flat, even white-collar workers living area, open 1.6L car from work, flew 12 times a year, carbon emissions will also be 2611 kg. Seen in this light, energy conservation is imperative. If the protection of the environment, animal protection, energy conservation has become a code of conduct of these more environmentally friendly, low-carbon life is even more urgent need to establish a green lifestyle.

“Low-carbon life” though is a new concept, the proposed sustainable development is the old problem of the world, it reflects on the human due to climate change concerns about the future of the world’s growing consensus on this issue. Global warming and other climate issues have led to consideration of the present human environment. Aware of human production and consumption occurs during the formation of excessive carbon emissions is an important factor in the climate issue, which would reduce carbon emissions to the corresponding constrained optimization, and some consumption and production activities. Although the causes of climate change, there are still scholars have different views, but because of “low-carbon life” concept at least conform to the human “rainy day” the precautionary principle and the pursuit of perfect mental and ideal, and therefore “prefer to believe them, do not want to believe No, “low-carbon life” concept also gradually accepted by the world. The emergence of low-carbon life, not just tell people, you can do to reduce carbon emissions, but also to tell people how you can do. Gradual rise in this life time, we began to care about, today I have to reduce carbon emissions do? Badaling in Beijing, a forest carbon market has been forming. If you want to offset their carbon emissions, carbon sinks can come here to buy forest or planting trees. Forest carbon sequestration through the implementation of afforestation and forest management, restoration and other activities in the chloroplasts of plant leaves through photosynthesis, absorb water, soil, where salts and water, releasing oxygen through the sieve to create organic matter and then transported to the earth, soil fungi and bacteria in decomposing organic matter then, resulting in material cycle, in terms of play for the carpet to reduce the role of carbon dioxide in the air. Compared to driving less and less air conditioning, buying the idea of forest carbon sinks, will be more welcome. Currently, the main measures to mitigate climate warming is the emission reduction and increasing exchange. Compared with the emission reduction measures, because of their low-cost forest carbon sequestration measures, more effective, easy to operate, as an important means to mitigate climate warming.

Background

Greenhouse gases make the Earth a fever. 200 years, as the industrialization process in depth, a lot of greenhouse gases, mainly carbon dioxide emission “injured” in the earth, global warming, climate change, it is an indisputable fact. December 8, World Meteorological Organization announced in advance, “the global climate in 2009″ report, nearly 10 years the hottest on record worldwide for 10 years. In addition, global warming makes the Antarctic ice begins to melt, leading to rising sea levels. Finnish and German scholars to the latest survey shows that sea levels this century may rise 1.9 meters, far beyond previous expectations. If this continues, the South Pacific island nation of Tuvalu will probably be the first to disappear in the sea of the island.

U.S. media published on December 5, a study found that the Earth has a fever caused tremendous human health crisis. First, increased allergies, research shows that with the carbon dioxide level and temperature gradually increased, the advent of flowering in advance, so that pollen formation increased, so that the spring allergy increase. Second, the species is becoming more and more “pocket”, as global warming, bio-physical in the smaller, which has Xianduan Ni from the Scottish sheep. Third, the kidney to increase, due to rising temperatures, dehydration increased, the researchers predict that by 2050, will add 220 million patients with urinary stones. Fourth, foreign infectious disease outbreaks, the water temperature rises, will breed mosquitoes and plankton, to dengue fever, malaria and encephalitis outbreaks from time to time. Fifth, increased pulmonary infection in summer the temperature increases, the cool breeze will increase to reduce ozone pollution, can easily lead to lung infections. Sixth, the proliferation of disease-causing algae, water temperature led to the rapid proliferation of algae, from the municipal water supply system to the natural lakes are contaminated, causing the digestive system, nervous system, liver and skin diseases. Low-carbon life, has become an urgent need to establish the human way of life.

Way to implement

Since climate change summit in Copenhagen on Dec. 7, 2009 since the opening, he was dubbed “the most important meeting ever”, “change to a low carbon life, the fate of the conference poster ball” and other heavyweight titles. The meeting attempted to establish a global framework for greenhouse gas emissions, but also a lot of people’s current production and human life began deep reflection. Even if the world is still the issue of the hard emission reduction wrestling, but the concept of low-carbon almost been widely recognized.

Low-carbon, is lower or lower greenhouse gases (mainly carbon dioxide) emissions. The Chinese Society for Environmental Sciences told the Secretary-General Ren Guanping “Life Times”: “Energy is the largest carbon reduction.” The first major implementation of carbon reduction in production, such as the vigorous development of hydropower, nuclear power, wind and solar and other clean energy. Renguan Ping emphasized that carbon reduction is everyone’s responsibility. For us, the lifestyle portrayed everyone’s “carbon footprint.”

What kind of person could be considered “low-carbon family”, “low carbon” they represent? In short, “low carbon” is a lifestyle, a natural resources around them to the habit of saving, as long as you are willing to take the initiative to bind themselves to improve their living habits, you can join. Of course, the carbon does not mean we should intentionally go to thrift, deliberately to give up some of the enjoyment of life, as long as you do bits and pieces from more than life savings, do not waste, the same can live comfortable, “low-carbon life”.

Simple to understand, low-carbon life is back to nature to man and nature to carry out the activities, mainly from energy-saving solar terms and the three links of recovery to change details of life, including the following good habits of some low-carbon: carbon advocacy, care earth.

Develop low-carbon lifestyle

1. Daily Taomi Shui can be used to wash their hands clean furniture, clean, natural moisture.
2. Scrap paper will pave the bottom of the wardrobe, not only can absorb moisture, can absorb the smell in the closet;
3. Used paper and do not throw away the mask, use it to clean jewelry, clean the surface of furniture or wipe belt, not only can leave a polished bright paper mask the aroma;
4. Drink tea residue, dry it, make a tea pillow, comfort, and help improve sleep.
5. Go out shopping, bring your own bags, whether free or charging for plastic bags, both to reduce the use.
6. Out comes water cup, reduce the use of disposable cups.
7. Multi-permanent chopsticks, lunch boxes, avoid using disposable tableware.
8. Cultivate the habit of readily switch off the appliance, to avoid wasting electricity.
9. Try not to use the refrigerator, air conditioner, fan or a fan can be hot.

After manual re-creation of DIY, you will find the original waste is also a treasure, this home environment healthy and full of creative little joy. “Low Carbon Pioneers” is in the details of your life to change that: climate change is no longer just environmentalists, government officials and scholars concerned with the problem, but is closely related to each of us. In the promotion of healthy living has become a trend today, “low-carbon life” is no longer just an ideal, but also a new way of life to look forward.

There are not easy to pay attention to several points:

1. Daily conventional winding alarm clock to replace the electronic alarm clock;
2. In the lunch break and after work, turn off the computer power supply;
3. Once without lights, air conditioners and turning off; phone when charging is complete, immediately unplug the charger plug;
4. Choose to dry clothes, avoid using tumble dryers; used in a nearby park for jogging in place with fresh air instead of jogging on a treadmill 45 minutes exercise;
5. Replace 60-watt lamps with energy-saving light bulbs; not drive a car and started riding a bike, or walking.
6. In using the computer, try using low brightness, and so less open process, so you can power-saving.

Low-carbon life on the know-how

Refrigerator storing the amount of food in order to account for 60% of volume is appropriate, put too much or too little, all expenses electricity. Food between the food and the refrigerator should be between the low-carbon life posters left over the gap of about 10 mm. Plastic box with a number of water containers, made of ice in the freezer into the refrigerator after, this can be extended downtime, reduce boot time.

Higher starting current air conditioning, frequent switching very cost electricity, and easy to damage the compressor. The fan on the air within the machine below, use fans to improve cooling effect of wind. Shortly after the open air open fan. At night could not have air conditioning, power nearly 90%. Set in the desiccant air-conditioning mode, then even if the room temperature can cause feeling slightly cool, and power than the cooling mode.

Washing machine washing in the same length of time, the weak file work, the number of large motor starting, say, than actually using the thing as a weak file saving, and extend the life of washing machines. By speed 1680 r / min (for turbo) 1 minute calculation dehydration, dehydration rate of up to 55%. General dehydration less than 3 minutes. Extended drying time is not meaningful.

Microwave oven than dry food and water after mixing evenly, polypropylene plastic wrap before heating cover or wrap, or use the heat of the glass covered heating. Each heating or cooking of food is appropriate to not more than 0.5 kg, preferably cut into small pieces, quantity heating time should be divided, among them mixing. Possible use of “high fire.” When thawing foods in order to reduce the number of microwave switches can advance food moved from the refrigerator freezer refrigerator, thawed slowly, and make full use of frozen food in the “cold energy.”

Computer short time without the computer, enable the computer’s “sleep” mode, energy consumption can be decreased to below 50%; turn off unused programs and speakers, printers and other peripherals; less to the hard disk, floppy disk, CD-ROM at the same time work; appropriate to reduce the display brightness. Laptop computer with special attention to: the battery fully discharge; try not to use external equipment; closed temporarily use the equipment and interfaces; close the screen saver; reasonable choice of shutdown mode: when the immediate need to restore a “standby” battery to use the election “sleep” for a long time do not select “Shutdown”; battery to use while in WindowsXP / VISTA, through SpeedStep technology, CPU automatically reduced frequency, power consumption can be reduced by 40%.

Gas with low heat cooking fires than in a short time, can reduce heat loss. But we should not let the fire beyond the bottom of the pot, so as not to waste gas. Summer high temperatures do not boil the water before stamping so that the air temperature is lower than the water and air for heat exchange, and other natural warming of air temperature, and then affix to boil, saving gas. Before cooking, dry the pot outside the first drop of water, to cook the food as much as possible without steaming cooking, hard boiled food without using a pressure cooker or cooking fumes from stainless steel pot, cooked food using microwave heating method, etc., also help to save gas.

Short will open is also a saving, lighting, air conditioning, public address can save electricity. About to expire perfume, can be sprayed on the dried flowers, stuffed pillows, the washing water and the drag on the floor. If not immediately unplug any electrical plug.

Try to use public transport, car shopping go shopping to have plans, as one stop shopping. More walking, cycling, ride light rail subway, drive less. Energy-saving drive: to avoid cold start, reducing idling time, avoid sudden speed, choose the right running gear to avoid the low-grade high-speed, regular oil changes, high-speed Mo windows, tire pressure should be appropriate.

More use of e-mail, MSN, QQ and other IM tools, small fax printers, and more tree planting. Eat with bags of food, reducing the use of the number of bags.

More by bus. Transport of carbon dioxide greenhouse gas emissions account for more than 30% reduction of such emissions is one of the best ways: By bus. American Public Transportation Association, said public transportation to save nearly 5.3 billion liters per year of natural gas, which means to reduce 1.5 million tons of carbon dioxide emissions.

Persist in small practices

1. Less take a second elevator, on reducing carbon emissions 0.218kg
2. Less air conditioners one hour, to reduce carbon emissions 0.621kg
3. A small electric fan 1 hour, to reduce carbon emissions 0.045kg
4. Less watching TV 1 hour, on reducing carbon emissions 0.096kg
5. Less lamp 1 hour, to reduce carbon emissions 0.041kg
6. Less drive 1 km, on the reduction of 0.22kg of carbon emissions
7. Eating 1 fast food, the reduction of 0.48kg of carbon emissions
8. 1kg less burn paper money, to reduce carbon emissions 1.46kg
9. Less waste lost 1kg, 2.06kg to reduce carbon emissions
10. Eat 1kg of beef, 13kg of reducing carbon emissions
11. Province kilowatt, the reduction of carbon emissions 0.638kg
12. Province was once water on the reduction of carbon emissions 0.194kg
13. Province, once natural gas, reduce carbon emissions by 2.1kg
14. If you do every day, every day we can reduce carbon emissions 21.173kg

If all the Chinese can do for each person per day each, then we can reduce the 29642200000kg day carbon emissions.

If the world can do for each person per day each, then we can reduce the 1058650000000kg day carbon emissions.
