BEE (Bureau of Energy Efficiency)

Energy Efficiency may be the most discussed words while shopping for electrical appliances. But since the terms are purely technical and there are several variations like capacity, speed and efficiency common man stand puzzled before the shop keeper. So some indications are required to easily identify the power efficiency of an electrical appliance. Here comes a BEE (Bureau of Energy Efficiency) label star rating. The BEE Star Energy Efficiency Labels have been created to standardize the energy efficiency ratings of different electrical appliances and indicate energy consumption under standard test conditions. BEE (Bureau of Energy Efficiency) label indicates the efficiency of the equipment with 1-5 stars. The more star the label bears the more efficient it will be. For example a 5 star rated AC or refrigerator is more energy efficient that an appliance bearing 4 stars. So go for maximum stars while you purchase an electrical appliance. The more stars means more energy efficiency and the more money it will save over the life. Energy saving is for your pocket and for the self reliance of our country.

The Engineering Toolbox

The Engineering Toolbox is a nice place for Electrical and other engineers for a quick reference into complicated equations and formulae.

How much energy is your home or office building wasting?

How much energy is your home or office building wasting? Have you ever asked this question yourself? If not try to find out a few loop holes where the energy is losing. The United States Green Building Council estimates that commercial office buildings use 20 per cent more energy on average than necessary. The problem is that we don't know where the energy is lost. A simple solution is remote energy monitoring. Learn more about energy efficiency and save money on regular basis.

Now it is easy to improve your building’s efficiency. Download “Monitoring Energy Use: The power of Information” free of cost from www.sereply.com

Electricity Consumption by the Control System

Electricity Consumption by the Control System is an important factor in energy efficiency terms. A 400Ampere breaker consumes about 200 units of energy in an year! similarly the 5W indication lamp consumes about 50 units an year. So the ON OFF indication on a panel consumes 100 units an year. A control panel normally contain several indication lamps, coils etc. ( I am not considering the energy consumed by the long control cables). So it is important to address this problem while you design control circuits and control panels. On simple step towards energy efficiency of control panels is by selecting energy efficient components.

Pros and Cons of Compact Fluorescent Lamps (CFL)

The cost of Compact Fluorescent Lamps (CFL) decreased since 1999. Now the power saving of Compact Fluorescent Lamps (CFL) is more than the initial cost for installing these energy efficient lamps. The countries like European Union etc are trying to ban incandescent lamps and switch completely to Compact Fluorescent Lamps (CFL). In this short article I am trying to investigate on the pros and cons of Compact Fluorescent Lamps (CFL) over incandescent lamps.

1. Compact Fluorescent Lamps (CFL) consume about 25% of the energy required for lighting up with incandescent lamps.

2. The life span of Compact Fluorescent Lamps (CFL) is 10 times more than that of ordinary incandescent lamps.

These two aspects contributes for energy saving and lower CO2 release worldwide. Now let us compare the cons of using Compact Fluorescent Lamps (CFL).

1. The toxic mercury contained in Compact Fluorescent Lamps (CFL) is one major drawback. Also the lead contained in electronic circuit poses danger.

2. Compact Fluorescent Lamps (CFL) takes longer time to light up and people may incline to keep this turned on when it is not required.

3. The cost of production of Compact Fluorescent Lamps (CFL) is more and the cost of recycling is also very high and this may neutralize some of the cost saving archived by CFL.

4. Compact Fluorescent Lamps (CFL) are very much sensitive to temperature variations and hence it is not suitable for external lighting.

5. In cold countries the incandescent lights contribute to room heating. This is not possible with Compact Fluorescent Lamps (CFL).

6. With Compact Fluorescent Lamps (CFL) dimming is not possible.

7. The light emitted by Compact Fluorescent Lamps (CFL) is confined to a smaller spectrum range and is a bit itching to eyes.

This may invite deeper thinking before implementation of Compact Fluorescent Lamps (CFL) by banning incandescent lamps. We may have to wait for Solid State Lighting (SSL) like LED lighting to save on energy and lights.

Energy Saving Lamps Vs Conventional Lamps

Energy Saving Bulbs help you to save energy at home. Energy Saving Bulbs can save up to 80 percent of energy compared to conventional incandescent lamps. We have compact fluorescent lamp (CFL), also known as a compact fluorescent light and Light Emitting Diodes. The increasing energy costs and the increase in CO2 and Global warming issues can be tackled only by using energy efficient lamps and bulbs at home. Use of energy saving lamps at your home to reduce energy bills. It also reduce global warming by reduced energy consumption. Remember the CFL campaign organized by KSEB.
