Energy-Efficiency Improvement Opportunities In Lighting System

There are a lot of opportunities to optimise lighting system in (almost) any industrial facility. Seven practical energy-efficiency opportunities to reduce energy use cost-effectively are given below:

1) Lighting controls

2) Replace mercury lights with metal halide or high pressure sodium lights

3) Replace metal halide (HID) with high-intensity fluorescent lights
4) Replace magnetic ballasts with electronic ballasts

5) Optimization of plant lighting (Lux optimization) in production and non-production departments

6) Optimum use of natural sunlight

What is Biodiesel?

1) A clean burning alternative fuel, produced from domestic, renewable resources such as plant oils, animal fats, used cooking oil and even new sources such as algae.
2) Contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend.
3) Biodiesel blends can be used in compression-ignition (diesel) engines with little or no modifications.
4) Simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.
5) Biodiesel is not raw vegetable oil.
6) Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to ensure proper performance.
7) Biodiesel is also not the same as ethanol. Ethanol is a renewable biofuel made primarily from corn and intended for use in gasoline-powered engines, while biodiesel is a renewable biofuel made from a variety of materials and designed for use in diesel engines, with different properties and benefits.

Smart Grids and The New Age of Energy
The present electric grids use the technology of 1970’s. But with the advancement in various concepts of power generation, problems associated with power outages and thefts, and also due to increase in demand, we require a modernized grid to avail all the needs of customers even in the situations of hype, which can be called a “smart grid”.

The smart grid performs various functions such that it increases grid stability, reliability, efficiency and ultimately reduces line losses.

Also the smart grids are designed to allow the two-way processing of electricity from consumers that have distributed generation. Various technologies like sensing and measurement, usage of advanced components are to be used for successful functioning of the grid.

1) Increasing reliability, efficiency and safety of the power grid.
Enabling decentralized power generation so homes can be both an energy client and supplier (provide consumers with interactive tool to manage energy usage).
2) Flexibility of power consumption at the client’s side to allow supplier selection (enables distributed generation, solar, wind, and biomass).
3) Increase GDP by creating more new, green collar energy jobs related to renewable energy industry manufacturing, plug-in electric vehicles, solar panel, and wind turbine generation, energy conservation and construction.

Some Safety Rules for Working with Electrical Equipment
Avoid contact with energized electrical circuits

Treat all electrical devices as if they are live or energized
Disconnect the power source before servicing or repairing electrical equipment.

Use only tools and equipment with non-conducting handles when working on electrical devices

When it is necessary to handle equipment that is plugged in, be sure hands are dry and, when possible, wear non conductive gloves, protective clothes and shoes with insulated soles.

If it is safe to do so, work with only one hand, keeping the other hand at your side or in your pocket, away from all conductive material. This precaution reduces the likelihood of accidents that result in current passing through the chest cavity

Minimize the use of electrical equipment in cold rooms or other areas where condensation is likely. If equipment must be used in such areas, mount the equipment on a wall or vertical panel

If water or a chemical is spilled onto equipment, shut off power at the main switch or circuit breaker and unplug the equipment.

If an individual comes in contact with a live electrical conductor, do not touch the equipment, cord or person. Disconnect the power source from the circuit breaker or pull out the plug using a leather belt.

Tricky situation, and you must be very calm in order not to make the situation even worse.

Never handle electrical equipment when hands, feet, or body are wet or perspiring, or when standing on a wet floor.

When it is necessary to touch electrical equipment (for example, when checking for overheated motors), use the back of the hand. Thus, if accidental shock were to cause muscular contraction, you would not “freeze” to the conductor.

Do not store highly flammable liquids near electrical equipment
Do not wear loose clothing or ties near electrical equipment. Act like an electrical engineer, you are not on the beach.

Why modern buildings MUST have energy metering and monitoring system?
The first step to greater efficiency through energy metering and monitoring is to set objectives for the future system.This step is essential to identifying user needs and determining the scope of the future energy monitoring systemThe main applications of an energy monitoring system are //
Energy cost allocation
Energy sub-billing
Energy usage analysis
Building energy performance benchmarking
Electrical distribution asset management
Bill auditing (shadow metering)
Energy procurement

More than 85% of the electrical energy input to an air compressor is lost as waste heat, leaving less than 15% of the electrical energy consumed to be converted to pneumatic compressed air energy. This makes compressed air an expensive energy carrier compared to other energy carriers.the procedure of conducting a detailed energy assessment of the compressed air system as well as the energy efficiency opportunities are described.

Reduction of demand
Maintenance
Monitoring
Reduction of leaks (in pipes and equipment)
Electronic condensate drain traps (ECDTs)
Reduction of the inlet air temperature
Maximizing allowable pressure dew point at air intake
Optimizing the compressor to match its load
Proper pipe sizing
Heat recovery
Installing adjustable speed drives (ASDs)
