The Indian economy is growing at a tremendous rate. With the development in the industrial sector, people too are aspiring for a better lifestyle. In this regard, the surge in energy demands in the near future is inevitable. According to a report Understanding Energy Challenges in India: Policies, Players, and Issues, published in 2012, India witnessed a significant rise in energy demands in 2009 and was just behind China and the USA. Undoubtedly, the energy landscape of India is continuously expanding. Here we have shared a few key insights about the energy sector in India:
1. The New Policies Scenario or NPS discusses how India will be handling issues such as climate change, energy security and other issues relating to the energy landscape. It has projected that the energy demand in India will grow in the future and will reach 1464 Mtoe by 2035. It is expected to increase by a CAGR or Compound Annual Growth Rate of 3.1% from 2009 to 2035. This is more than double of the total energy demand across the globe.
2. By 2035, India’s share in the global energy demand will grow to 8.6%. In 2009, India’s share in the world energy demand was 5.5%. This growth is projected to come from coal and is expected to triple to a whopping 618 Mtoe in 2035 from 280 Mtoe in 2009. Apart from that, the demand for oil is also expected to grow to 356 Mtoe in 2035 from 159 Mtoe in 2009.
3. In case of natural gas, the energy demand would be 48 Mtoe in 2035 from 5 Mtoe in 2009. On the other hand, the demand for renewable sources of energy will grow to 36 Mtoe from 2 Mtoe. The report predicted that the hydrocarbons will primarily drive the huge energy demands in India.
4. After the economic reforms in 1991, India has witnessed a considerable transformation in its energy mix. One of the most noted changes in the energy mix of India was the shift from biomass to other sources of energy, especially coal. This signifies the rapid urbanisation and economic development of the country. In 2009, coal was the biggest source of primary energy in India (42% share).

Energy is one of the most important commodities in India, particularly in the industrial sector. After the USA, China, and Russia, India stands fourth in terms of high level of energy demands. The energy consumption in India has increased by 80%. In 2002, the total percentage of energy consumption was 30 Mtoe while in 2012, it was 564 Mtoe. Energy cost, in India, constitutes about 10% to 20% of the total cost. And, industries nowadays are seeking efficient energy management solutions to optimise costs and improving competitiveness. Let’s take a look at the energy management scenario:
1. For implementing effective energy management solutions, the organisations need to take a holistic approach towards energy usage. A deep understanding of the total energy consumption is essential for development and optimisation of energy management solutions.
2. Energy Management is the process which is undertaken with a primary motive of resource conservation, cost saving, and climate protection. Industries mainly target three areas for energy management: managing their energy supply, reduction in energy wastage, and utilising technology for energy efficiency.
3. In the recent past, renewable sources of energy have emerged as one of the most reliable options for procuring energy. Companies are mostly resorting to renewable sources of energy not only from the perspective of sustainability but also due to the increased competitiveness of these resources.
4. Till 2013, the solar power installed capacity has witnessed a considerable growth. Until October 2013, more than 2000 MW of solar power facilities has been installed. However, more than 70% of these facilities are concentrated in Rajasthan and Gujarat.
5. Monitoring and metering remain the heart of efficient energy management solutions. Metering helps in assessing your energy performance and spotting the problem areas that are leading to higher energy consumption. The analysis and comparison of bills and meter readings give you a comprehensive idea of the patterns of your energy usage.
Simple steps such as monitoring thermostat, changing light fittings, replacing faulty machinery can open your ways to energy saving opportunities. Apart from that, you can even install an energy management system for optimising your energy usage.

With rising energy costs, business across India and other parts of the globe are looking forward to energy saving tactics. From cutting down lighting costs to installing an energy monitoring system, industries are implementing various techniques to reduce their energy consumption. Let’s take a look at a few efficient ways of reducing industrial energy consumption:
1.Reduce Process Heating
In the manufacturing industry, process heating alone claims a major part of the total energy consumption. This can be reduced by implementing energy saving practices. This is sure to make a big impact on the industry. You can monitor and regulate the exhaust gases, heat transfer improvements, air-to-fuel ratios, and waste –heat recovery technology. For instance, if your manufacturing process involves using a large amount of hot water, you can pre-heat the water by using a solar water heating system. This can significantly reduce the energy consumption of your manufacturing unit.
2.Install Energy Monitoring System
An energy monitoring system is the best way to control, monitor, and reduce the level of energy consumption. With an energy monitoring system you can easily manage and regulate the lights around your industrial plant and other energy consuming devices such as the thermostat, and motors etc. The energy monitoring system can efficiently monitor your energy consumption in real time. This system can be installed quickly, so, there is no scope for disruptions.

Industries are driven by machines, which accounts for more than 20% of the total energy usage. By upgrading your machinery to a higher efficient system, you can significantly lower the operating cost of your industrial plant. For this, you might have to replace a few old machines. Improving the mechanical performance of your plant will automatically reduce the maintenance and energy cost.
4.Energy Saving Lighting
Install energy saving lighting options for reducing your energy usage. You can install fluorescent lights and fixture, install a solar panel to increase your daylight consumption further or try LED bulbs. This will bring down your energy costs efficiently.
Whenever planning for implementing energy saving techniques, always explore the low or no-cost opportunities first. Hopefully, these pointers will help you gain some insights into this matter.
The majority of the power or energy producing devices operate in cycles. Power cycles basically convert a heat input into a mechanical output. In case of a power plant, its thermal efficiency defines its performance. And for a better efficiency, the power plants are required to utilise efficient thermal or power cycles. Let’s find out more about power cycles:
1. To generate electricity, two thermodynamic cycles namely Rankine and Brayton’s cycles are widely used. These cycles can also be referred as power cycles as they too perform the task of converting heat input into mechanical output.
2. The Brayton’s cycle is a conventional cycle (a gas turbine open cycle) in which the air is first compressed and then burned in a combustor. The hot gas thus produced is then expanded in a turbine attached to an electric generator. On the other hand, in a closed cycle the working fluid is first compressed. This is followed by a heating process and then the fluid is further expanded in a turbine. Afterwards, the hot gases are then cooled down before they are compressed and the recycled. This power cycle can be further improved by introducing a reheat via a second combustion chamber, intercooler, and then introducing a recuperator to heat up the liquid which is entering the combustor, thus, reducing fuel consumption.
3. The Rankine cycle is generally used in steam power plants. This cycle produces high temperature and high pressure steam by utilising a steam generator. The steam generating from a boiler is first expanded by using high and low pressure turbines which then convert the energy into mechanical shaft work which drives the electric generator and produce electricity. During the final turbine step, the steam is further send to a condenser from where it is again driven back into the boiler, thus repeating the cycle. Efficiency in this cycle is achieved by introducing reheats and regeneration steps.
4. A combined cycle comprises of a gas turbine (Brayton Cycle) for generating electricity. The waste heat is further used in a recovery boiler in order to produce steam (Rankine Cycle) for generating electricity using a steam turbine. This improves the overall efficiency of electricity generation.
