Impact of Wind Power in India

  • Monday, 25 January 2016

  • Rajesh K
  • India is the fourth largest generator of electricity through wind energy/wind turbines. The potential of wind power in India has been assessed to be 300 GW. As of Nov. 2015, the installed capacity of wind power in India is estimated to be slightly less than 25 GW. Wind power contributes to around 8% of the power generation capacity in India, and it contributes to 65% of power generation capacity among renewable power sources in the country.

    Top 5 Indian States with the Highest installed Wind Power capacity: Tamil Nadu, Gujarat, Maharashtra, Rajasthan & Karnataka. Tamil Nadu contributes to around 35% of the total wind power capacity in India. Gujarat is estimated to have the maximum gross wind power potential in the country. The Government of India aims to achieve 60 GW of wind power by 2022.

    Largest Wind Farm in India: Muppandal wind farm, Tamil Nadu (1500 MW capacity).

    Suzlon, an Indian-owned company, is one of the major manufacturer of wind turbines across the world, and has an installed capacity of more than 6.2 GW in India alone. The major wind turbine manufacturers active in India include Suzlon, GE, LM Wind Power, Vestas, Gamesa, Siemens, ReGen Powertech, RRB Energy, Inox Wind, etc.

    2.5 MW and 2.8 MW Wind Turbines are among the largest capacity wind turbines installed in India with massive rotor diameters of approx. 100m & 109m respectively. Offshore wind farms are being considered to be developed in the Indian states of Gujarat and Tamil Nadu. Accelerated depreciation and other incentives are available for businesses installing wind power capacity in India. 

    The Indian Wind Energy Association (InWEA) is a non profit organization that is dedicated to the promotion of wind energy in India. Ministry of New and Renewable Energy (MNRE), is the Government body that oversees the policy and development of renewable energy, including wind energy, in India. 

    A Wind Resource Map, indicating the wind power potential of various regions of India is available online. Indian Wind Power, managed by Indian Wind Power Manufacturer's Association, is a dedicated magazine that publishes regular news and articles about wind power in India. You can read many articles related to technology, policy, investment, etc. in the wind energy sector, from here. 

    Hybrid Solar-Wind and Solar-Hydro power projects are common in India as two forms of renewable energy can combine together and compensate for one another during periods of low production. Besides, there is a lot of space available in wind energy sites where solar panels can easily be installed, to compliment the energy generated by wind. Wind turbines can even be installed on farms and other useful land without interfering with regular activities. 

    As you can see, wind power has the potential to create enormous impact in India and the Govt. is rightly targeting to become a superpower in Wind Energy.

    Impact of Solar Power in India

  • Saturday, 23 January 2016

  • Rajesh K

  • The amount of solar energy available for tapping in India in a year is more than the capacity of all the fossil fuel reserves in the country! Solar energy is obviously a natural resource that is available in abundance (and for free) in India, which we have started utilizing in a large scale over the last few years. However, solar power can/should create an even higher impact in the electricity generation scenario in India. 

    As of July 2015, the total installed capacity of solar power in India is around 4 GW, while the total installed capacity of all forms of electrical utilities is around 285 GW. India is ranked No.1 in terms of solar energy production capacity per watt installed. The demand is ever increasing and fossil fuels can only generate so much electricity. Clearly, there is a lot of scope for solar power to create a larger impact in India.

    Top 5 Indian States with Highest Installed Solar Energy Capacity:

    1. Rajasthan - 1199.70 MW
    2. Gujarat - 1000 MW
    3. Madhya Pradesh - 673.58 MW
    4. Maharashtra - 378.70 MW
    5. Andhra Pradesh - 279.44 MW
    Top 5 Largest Solar Power Projects in India: 

    1. Charanka Solar Park, Gujarat - 221 MW
    2. Welspun Solar MP Project, Madhya Pradesh - 151 MW
    3. Sakri Solar Plant, Maharashtra - 125 MW
    4. Green Energy Development Corporation, Odisha - 50 MW
    5. Tata Power Solar Systems, Madhya Pradesh - 50 MW
    Solar power can be installed on unproductive and barren land with a high solar irradiation. These solar power plants need to be connected to the grid, which needs to be arranged by state-run electrical utility agencies. Or, micro grids can be established in the areas surrounding solar power plants and the electricity can be used right there. Micro grids are an efficient way to utilize power as transmission losses are minimized. 

    The requirement of land for solar power projects (6 acres per MW) is similar to other utilities like coal-fired power plants and hydro-electric power plants. Solar power plants are not dependent on supply of raw materials as they receive free sunlight from the sun. Although land availability is a challenge, people are approaching this challenge in interesting ways by co-locating solar panels along with wind energy projects, on the top of roofs of residential and commercial buildings, and even on the top of canals which has an additional benefit of reducing water loss due to evaporation. 

    The Govt. of India has been encouraging solar projects and solar power plants through various schemes and incentives for power producers, large organizations and even individual houses. There is subsidy for solar lanterns and solar pumps for the rural and agricultural sector; there is subsidy for solar water heaters and solar power plants for individual houses; there is acceleration depreciation, capital depreciation, assured power purchase agreements and renewable energy certificates for commercial organizations. 

    As you can see, solar energy has already created a good impact in India, and the demand for solar power is going to only increase and become more popular in the near future. Solar energy has a lot of potential in India and everyone should unite to create an even larger impact that would satiate our power requirements while not harming the nature.

    Solar Panels spotted at Poompuhar!

  • Tuesday, 29 December 2015
  • by
  • Rajesh K
  • Poompuhar is a remote coastal village in Tamil Nadu and I went there recently for a tour. It used to be an important port, but most of this erstwhile town has drowned into the ocean now. They have constructed a light house and one of the buildings inside the light house complex had solar panels installed on the top. I took the above picture from atop the light house, as visitors are allowed to climb it.

    I was glad that solar panels have reached small remote villages. It also makes sense for them to go solar because the power supply in such places is generally sporadic and unreliable. Along with a battery, they can at least power some important electrical appliances when there is no power. I hope solar power reaches more villages and towns where the power supply is not reliable.

  • Rajesh K
  • The world's first fully solar-powered airport will be inaugurated on coming Tuesday, August 18, 2015 by the Honorable Chief Minister of Kerala, Shri. Oomman Chandy at Kochi International Airport. The new 12 MWp solar power plant has been commissioned by Bosh India - Bosch Energy & Building Solutions. This will augment the already existing 1 MWp solar power plant, in the international airport premises. 

    The Kochi International Airport's requirement of 50,000 units per day is estimated to be fully met by the new solar power plant, and excess energy will be sold to the state electricity board. The new solar plant has been commissioned over 45 acres of land and comes at an investment of roughly 62 Crores.

    Urban Tree Green Homes & Blogger's Meet

  • Urban-Tree-echo-VME-Bloggers-Meet-Chennai-r

    I went to a Blogger's meet organized by Urban Tree Constructions and echoVME in Chennai, last Saturday. Here, as usual, there were some events like quiz & adzap but the presentation by Urban Tree Constructions about Green Homes in Chennai, and how they are striving to make their properties (residential apartments) more green, impressed me much. In the above photo, you can see the CEO of Urban Tree addressing the gathering of Bloggers. 

    Here are some highlights on Urban Tree's Green Home Initiatives:
    • They use heat-reducing glass panels instead of normal glass panels (that allow all the heat to get in). This reduces the amount of air-conditioning necessary to cool the houses. 
    • They use low VOC paints that have reduced lead (and other chemicals) that are harmful. 
    • They use solid concrete blocks made with fly ash, which is a waste product from other industries. 
    • Recycled water from sewage treatment plant is used for flushing and gardening. 
    • Rainwater from terrace is collected and used for irrigation. 
    • They have fixed Aerators and other water-saving fixtures, reducing water consumption.
    • They use larger windows so that more light comes in and the requirement for daytime lighting is reduced. 
    • Walls are gypsum-plastered, so heat coming in from outside is reduced. 
    • LED lights (in common areas) and CFL bulbs reduce electricity consumption. 
    • Thermal roof insulation tiles reflect sunlight and reduce heat penetrating inside. 
    • Waste segregation and management/recycling processes are followed. 
    • Landscaping around the apartments, including over one-lakh saplings planted in one of their apartments (Oxygen) helps maintain greenery and a more pleasant appearance/climate. 
    • IGBC Green Buildings Certification enables standards-based compliance to green homes. 
    • CFC-free air conditioning reduces ozone pollution. 
    I spoke to their CEO for a short time and upon my suggestion, he said he will consider Solar Water Heaters for their properties in the future. Yay!! :)

    Let us raise our Voice against Dirty Power #AbMontuBolega

  • Friday, 10 July 2015

  • Rajesh K

  • With increasing population, our energy needs are only going to multiply. While we may not be able to decrease our energy consumption in the near future, we can at least ensure that we consume energy efficiently, and use renewable energy for our power requirements. 

    Why burn more coal and oil? Don't you think we have already created enough pollution? Don't you think we have already done enough damage to the air, water, and earth? As responsible citizens, should we not raise our voice against dirty power. Is it not our responsibility to make sure that all of us use clean energy as much as possible?

    Why should we destroy forests, cut trees for firewood? Why should we pollute the earth by burning coal? Why should we fight our brothers and pay a huge price for extracting and distributing oil? Why should we continue damaging the earth & ourselves? Why should our future generations pay for our inefficiencies and wrong choices? 

    Think of the conditions in which labor is made to work in coal/petroleum industries. Think of how much their work environment - involved in extracting coal from mines deep down the earth, or petroleum, deep down the ocean. Why should our brothers suffer health ailments? So that we can live a comfortable life?

    Imagine the amount of carbon released into the atmosphere due to burning coal/oil. Global warming is real and will affect each and every one of us before our lifetime. Temperature of the earth is rising and low lying areas are already submerging into water. Polluting energy sources are a big source of carbon emissions. 

    Renewable Energy has developed to such a state that it is possible to power the entire earth using green energy, today. It maybe expensive compared to polluting energy forms, but we cannot attach a price to healthier and happier living, attainable through renewable energy. It is important that people collectively demand that to happen, in order for the political powers to make it happen. 

    It is easy to keep moving as we are, currently. But at some point, all our polluting energy resources are going to get exhausted or they will be so short in supply that it will become insanely expensive. Green technologies, including renewable energy, will be much sought after in teh future, and hence it makes a lot of sense to adopt, invest in them, from today.

    It's easy to turn a blind eye, but it's important for each one of us to promote green technologies that will make our lives better along with bettering the lives of our children and future generations. We should not only speak out against what we know is not the best option, but we should also set a personal example by adopting technologies like solar panels, micro wind turbines, etc. to power our homes, so that all our neighbors can become inspired by our positive actions, and follow us too. 

    If any of you head organizations, or are in decision making capacities, you should make sure to install renewable energy technologies to supply power to your facilities. This is not only possible today, but in many cases, feasible and better than grid connected power supply, today. If we take those small steps, slowly, the Government will also ensure than green technologies will power the grid. They are already promoting renewable energy in their offices and facilities, and are offering subsidies for private organizations to adopt green energy. But it's the people's enthusiasm and popular demand that will power this world through renewabels.

    Strepsils India has launched a campaign that enables everyone to raise their voice to create a Cleaner India/Swach Bharat. You can visit the links below to know more about the campaign and Participate in the same.

    There are places that need cleaning, people who deserve your attention & authorities who need to hear your opinions! Don’t be a silent spectator. Raise your voice and make a difference. Let's raise our voice and work towards a Swach Bharath!

    Honey, the modern day Elixir

  • by
  • Rajesh K
  • We all know honey is beneficial to health. But did you know that honey can help in weight management, or that honey can be consumed instead of sugar for healthier snacks, or that honey is a source of energy and aids in digestion? In this post, you'll find the health benefits and some important things you need to know about honey.

    Before that, I need to mention that I have started eating amla soaked in Honey occasionally to become healthier. I am spending a lot of time finding out what foods I can eat to enhance my health and honey was highly recommended, even in organic stores. I used to eat more honey when I was younger and I remember linking it. Once, we kids even took down a honeybee nest and tried to extract honey from it, but our hand-made honey was awful! :) You don't try - honey preparation is best left to professionals, I guess. 

    Here are some interesting facts, benefits, and answers about honey you must know:
    • Honey is sweeter and healthier than sugar, and hence is an excellent substitute for sugar. You can try adding honey instead of sugar while preparing certain types of foods.  
    • Honey is a good source of energy that keeps people active and it helps with digestion.
    • Eating honey helps in curing minor ailments like cold, cough, and throat irritation. 
    • Honey helps you get a more beautiful skin.
    • Honey is a natural food that contains carbohydrates, minerals, amino acids, proteins, minerals, etc. 
    • Honey can be taken in any season, including summer. It does not build heat.
    • The color of honey is not an indicator of its purity as honey comes in various colors.
    • Thicker honey is not necessarily purer than thinner honey.
    • Honey can be spread on bread instead of jam, can be used in tea instead of sugar, can be used in preparation of bakery items and desserts.
    • Crystallized honey can be returned to normal state by warming -- crystallized honey is not impure.
    • Honey is suitable for long-term storage, without refrigeration. 
    • Honey is known to have been used in the ancient times to cure ailments like gastric disturbances, ulcer, and skin-related ailments. 
    • A warm drink of lemon and honey, or honey and warm water in the mornings is good for health.
    • Apple slices can be dipped in honey and eaten, both for health and taste.
    • Honey can help you sleep better and improve memory.
    • Honey can be used to treat skins burns and wounds, especially when other medicine is not nearby.  
    • Ginger-Honey and Watermelon-Honey-Mint coolers are tasty and healthy drinks that can be made using honey. 
    • Eating honey and dried figs is said to increase athletic performance.

    The Best Way to Follow Cricket? UC Cricket!

  • Thursday, 9 July 2015
  • by
  • Rajesh K
  • I guess most of you might be familiar with UC Browser. It's a very popular web-browser for Android, iOS and other mobile platforms. Wait a minute, UC Browser is also available for Windows PC -- did you know that? I just installed it and it is as fast as Chrome -- I like it :)

    But this post is about UC Cricket, which appears as an icon on the UC Browser home page and enables you to follow cricket scores live, see results of recently concluded matches, check the schedule of upcoming matches/series, follow latest cricket news, see interesting & short cricket videos, etc. In short, you can follow all that's going on in the world of cricket from where ever you are, right on your mobile phone! 

    Before I write more about UC Cricket, I should mention one of my favorite features of UC Browser on my Android mobile phone - Facebook. Once you log in to your Facebook account, UC Browser remembers you and even creates a separate Facebook icon that you can keep on your home page. Without installing the heavy Facebook app, you can get all updates and notifications right from UC Browser! I just love it, especially since Facebook app and data can take a lot of memory.

    I like the live scores feature of UC Cricket. You can even see who is batting, who is bowling, etc. and it is updated in real-time. There maybe other apps to follow cricket scores live, but why download multiple apps for each application when UC Browser can do it all for you? That too without taking up much of the limited space available for app/data on your mobile?

    If you are a student, maybe you can sneak your phone into your class and follow cricket scores instead of following the boring lectures :P If you are working, maybe you can take the mobile to all those useless meetings and do something productive by following cricket scores at least :P 

    In this world where no one has time anymore to follow cricket on TV, it helps to have all the knowledge right on your hands so that you can flaunt it in front of your friends, colleagues or your boss. They are sure to admire how resourceful you are, in spite of having limited time for entertainment :)

    Did you know Pakistan won the three match test series against Sri Lanka recently? Did you know the Ashes test series is going on between England and Australia now? Did you know India tour of Zimbabwe will begin from Friday, 10th July? Did you know that India's tour of Sri Lanka in August could be advanced by a week so that the team will have some more time to relax before a grueling home series starts against South Africa? I am sure you didn't know all of these? I learned them by just browsing through UC Cricket on UC Browser for five minutes! 

    You can too. Just download UC Browser for your mobile -- Android, iOS, or Windows. And enjoy surfing the web :)


    Non-Renewable Energy posts/articles also from Now on . . .

  • Rajesh K
  • When I think about why I started this blog, I realize I wanted to inspire people from different walks of life -- whether they know much (or are interested in) renewable energy or not -- to implement renewable energy or at least become inspired to consider renewable energy. 

    But writing about renewable energy topics alone (as I am doing currently) is only going to bring people who want to know more about this topic. What about the innumerable others? How can I inspire them to adapt renewable energy in some form, in whatever little way, in their lives?

    That's why I have decided to write about many topics of interest to common man/woman in this blog. You can expect posts on music, organic products, movies, green buildings, mobiles, opinions, and many other topics that interests the common man, from now on. That will help me to bring more people in and (hopefully) interest them or make them curious about renewable energy. 

    Of course, I will also continue writing about renewable energy.

    Thanking you,

    Two Successful Years with Solar: MLC, Chennai

  • Monday, 29 June 2015
  • by
  • Rajesh K
  • I met Mr. Balachander (and team) of Manufacturing Logistics Control, Chennai, recently. They have installed a 5 KW Solar system two years ago, and another 1 KW solar system recently. I went to see the solar system in their premises and talk to them about their experience with the same.

    It seems they have been running almost everything in their office including AC, fans, lights, servers, computers, etc. for most part of the day using solar power generated by the 5 KW solar system . This system consists of 20 x 250 Wp panels, 5 KVA grid shared system inverter, 16 x 40 AH battery bank. When the power generated by solar power is insufficient, the power from the grid and batteries chip in. One important feature of their system is: Power from different sources is shared, not switched. 

    They use energy efficient appliances like Inverter ACs, LED lights, Super fan, etc. They also measure the amount of energy generated and the amount of energy consumed from each source, at every step. They have plotted a graph with energy bills before and after the installation of solar panel system and the savings is considerable. 

    Off-grid solar systems, which they recommend, has two important advantages over grid-tied solar systems. First, there is energy security for the customers as this system (with batteries) will provide non-stop power during the day and night, even during the few hours of power cuts. Secondly, customers will not face the problem of low voltage during the nights (which is common in many houses) as the system will compensate for the same.

    They feel that adopting energy efficient appliances has made a huge difference in accelerating the RoI after the installation of solar PV modules. They are now testing out a 1 KW system with a smart charge controller that can intelligently switch between battery power (via. solar) and grid power. 

    Based on their own experience they are planning to provide similar solutions for customers with existing Inverter systems. There are three common capacities of Inverters systems and hence solar panels, batteries, and other equipment are recommended based on it. So for 650 VA Inverter systems, they recommend one solar panel of 250Wp; for 850 VA Inverter systems, they recommend two solar panels of 250 Wp; for 1500 VA Inverter systems, they recommend four solar panels of 250 Wp. The battery capacity will be decided based on the number of hours of back up required. 

    As you can see, such a solution will require customization for each customer, and hence the company is willing to do an energy audit, and will recommend the appropriate solar system based on customer usage, existing appliances, etc. for each customer. You can contact them via the contact form available on their website

    Have a look at their blog post that contains detailed analysis after a year of running their office on solar power.

    Disclaimer: This blog post is for your information only and is not a recommendation. This blog is not affiliated with the above mentioned company in anyway and hence readers are recommended to do their own evaluation/analysis before deciding to buy any product or service from the company mentioned on this blog post.
    In this blog, I am taking baby steps to enable myself (and others) to adopt renewable energy technologies. Only if we know all the options available to us, we will be able to take informed and meaningful decisions, right?

    Let us learn what renewable energy technology options we have, who provides them and at what cost.

    Frankly, renewable energy in India (and perhaps the world) is still in its adolescence - Let us help it become a confident Man/Woman! And in the process, let us debate, analyze, form opinions and break them so that we can achieve the Utopian dream of Energy Security through Renewable Energy. Are you with me?
