Renewable energy is only the future. Escalating fossil fuel prices and the effects of the pollutants released by burning them has made world conscious of need to conserve energy and use natural resources like wind and solar energy.
Our nature has inexhaustible sources of energy which are capable of providing the energy needs of the whole world. Wind and solar are such sources available for us .
Renewable energy technologies are the future energy. We need to conserve conventional energy sources.
In fact Sun is the source of all types of energy on earth. We can also get electricity from sun using solar PV Panels and use in our day to day life.
Solar Electric generators commonly called solar pv panels are very useful in generating electricity from sunlight and capable of generating usable amount of power which can even run your utility meters backwards. It is right time to setup one at your house to save on ever increasing electric bills.
Solar Photo Voltaic panels can be configured in many combinations to meet your power requirements to a great extent. This can be useful for domestic as well as commercial use.

Energy Efficient Lamps
Compact Fluorescent Lamps
High efficacy lamp
Low wattage – less heat dissipation
Excellent color rendering
Long life – 8000~10000 glowing hours
Highly suitable for living rooms, lounges, corridors, hotels etc
Comparison of Incandescent lamp and CFL
Incandescent………Watts………40……….60……….100
---------------------Lumens……425……..720………1380
CFL………………......Watts……….9………..15………..20
---------------------Lumens……400……..900………1200
CFL are highly energy efficient
40% more lumens
Ideal for new projects and places where existing lighting is poor
Suitable for control room, labs, packing etc.

Energy saving in Lighting System
Terminologies
Flux emitted by lamp – Lumens
Luminous Efficacy – Lumens / watt
Illuminance = Lumens / Sq. Meter (Lux)
Colour rendering index – Colours of surfaces illuminated by a given light source.
Lighting is essential for any working environment
Power consumption is between 2% to 10%
The concept should be
The right light
At the right place
At the right time
At the right cost.
Initial cost is 15%
Operating cost is 85%.
We should focus on reducing operating cost of the lighting system.
So how do we do it
Use lamps of high efficacy
1. Compact Fluoroscent Lamps
2. Colar – 80 Series FTL
3. High pressure sodium vapor lamps for sheds, godowns, streets
4. LED Lamps

Energy Conservation at Macro level
Three major steps are involved
1. Capacity utilization
2. Fine Tuning
3. Technology up gradation
Excellent companies have tapped all three opportunities having three teams with common objective.
In every process
Energy input = Theoretical requirement + Unavoidable losses + Avoidable losses
The focus should be
a) To concentrate on avoidable losses
b) Quantify the losses
c) Identify ways and means for reduction in losses
d) Implementation.
Energy cost as % of manufacturing cost
Cement Industry..........35-40%
Paper Industry.............25-30%
Aluminum Industry......40-50%
Chemical Industry........20-30%
Engineering Industry.....5-15%
You can see the huge potential of savings which could be achieved even if we are able to save 10% energy.

Why Energy Efficiency
Increasing cost of existing resources led to increase in cost of energy.
In India, energy costs have risen by more than three folds in the last decade.
Energy cost is a major cost in production, excellence in energy efficiency ensures a healthy bottom line thru most productive consumption of energy.
Energy efficiency can be an effective competitive tool as it reduces cost of production due to saving in power consumption.
It enables resource conservation bringing down the need for more resources.
It also saves precious foreign exchange by reducing imports of fossil fuels.
It also leads to lesser pollution level and can contribute towards a better environment.
Benefits of Energy Efficiency
Efficiency of our equipments will improve.
By implementing various steps we can save 10% or more on our energy bills
Maintenance cost for equipments will be reduced.
