Solar Energy, Energy Audit, Energy Conservation and Energy Efficiency are common terms in India today.
The increasing demand for Power and subsequently Energy has led to considerable consumption of fossil fuels which has had an adverse impact on environment. In this context use of Renewable Energy such as Solar / Wind etc., Energy Efficiency and Energy Conservation is of paramount importance. It is estimated that great deal of Energy can be saved through Energy Conservation and Energy Efficiency and hence very critical for a energy-deficit Country like India.
It is established that by use of such measures global warming could be reduced to a permissible limit and also benefit all the stakeholders involved especially energy intensive units who could benefit from significant reduction in production costs due to energy conservation and improvement in energy efficiency.
In the Indian context there is a definite power issue and the peak deficit is estimated to be in the range of 12%-15% (latest 2012 figures). To overcome the power deficit problem a 2-pronged approach is needed -
It is no surprise that being a Solar-rich Country India will look at Solar Energy very seriously and very well supported by Government Subsidy and Incentive Programme under Jawaharlal Nehru National Solar Mission (JNNSM). Among all renewable technologies - PV Solar will prove to be the most useful due to its simplicity, modularity and maintenance-free nature. More about PV Solar and its reason for success can be found in our Solar Video Gallery.
Ever increasing price of energy is a good enough reason for Industries to opt for Green Energy and carry out Energy Conservation Projects (i.e. Periodic Energy Audit) for Energy Conservation as well as improving Energy Efficiency. More popularly known as Energy Audit - we believe that Energy Optimization exercise should not just end at Report Submission. Of course Report Submission is an integral part of Energy Audit but should be the first step towards achiveiving the overall objective of Energy Optimization. Mainly energy intensive Industrial Plants opt for Energy Conservation and Energy Efficiency through 3rd Party Energy Audit which basically forms the starting point. Energy Audit consists mainly of Electrical Energy Audit (for Electrical Energy Conservation and Efficiency) and Thermal Energy Audit (for Thermal Energy Conservation and Efficiency).
As India moves forward in the growth path., it faces a unique challenge that of Sustainable Development at the Growth Stage. To continue on the growth path we all need to adopt Green Energy and Energy Efficiency measures. The potential electricity saving in the Indian economy is large enough to wipe out the power deficit (around 12% peak deficit). It is estimated that nearly 25000 MW can be saved by implementing end-use energy efficiency and energy conservation measures throughout the Country (Facts & Figures). In summary we need to use Energy judiciously at an individual level, carry out Energy Conservation Projects at plant level and also give a though to power generation through green energy mainly Solar Energy (Solar Photo Voltaic).
Solar Energy simply means the Energy received from The Sun. The incident Solar Energy on our planet for ONE HOUR is enough to provide all the Energy needs of the plant for ONE YEAR !
1 HOUR OF SOLAR ENERGY INCIDENT = 1 YEAR OF EARTH'S ENERGY
ON EARTH NEEDS
The 2 types of Energy received from The Sun are Light Energy and Thermal Energy - both of which can be effectively utilized as an answer to the Energy Problems.
There are primarily 2 technologies -
Solar Photo Voltaic - Light energy of The Sun is directly converted to Electricity by means of using specialized Photo Voltaic Cells (PV Cells or Modules).
Solar Thermal - Heat energy of The Sun is used to super-heat water which is converted to steam. This steam is then used to run turbines. Alternatively water can also be heated for human use or Industrial Processes.
In general Solar Photo Voltaic Scores much above other renewable technologies including Solar Thermal - for Power Generation. Please visit our Section on Solar Energy to know more.
Energy Conservation and Energy Efficiency
Energy Optimization is a collective term for Energy Conservation and Energy Efficiency mainly achieved through Energy Audit.
Energy Conservation and Energy Efficiency are separate but related concepts. Energy Conservation is achieved when wasteful energy consumption is reduced, measured in physical terms. Energy Conservation can, therefore, be the result of several processes or developments, such as productivity increase or technological progress.
On the other hand Energy Efficiency is achieved when energy intensity in a specific product, process or area of production or consumption is reduced without affecting output, consumption or comfort levels.
Industries should actively consider Energy Conservation Projects (including Periodic Energy Audits and Frequent Walk-through Audits) - as an ongoing activity as it brings in tremendous benefits. Some of the obvious benefits of a Comprehensive Energy Conservation Programme are as follows :

In a nutshell it is clear that although Energy wastage is quite high in India (around 25,000 MW) but Energy Conservation alone will not help in bridging the gap of 15% peak deficit. A holistic approach to the power problem is
Energy Conservation - Saving energy where it is presently being wasted.
Energy Efficiency - Adopting efficient operations and advanced technology for reduced consumption.
Solar Photo Voltaic Power Generation - The cleanest, reliable and most preferred renewable power solution.
It is thus no surprise that Solar Energy and Energy Conservation & Energy Efficiency are the need of the hour and should be able to provide an answer to India's power problems of today and tomorrow.
