Energy Savers: Website on Energy Efficiency by BEE

  • Wednesday, 28 January 2015

  • Energy Savers is a website created and managed by Bureau of Energy Efficiency (BEE), Government of India. BEE is a Government body involved in energy efficiency regulatory and promotional functions including development of energy performance standards, energy conservation building codes; creating awareness and disseminating information on energy efficiency, preparing educational curriculum on energy efficiency, etc. 

    The website is focused more on creating awareness and giving information on energy efficiency best practices. For example, in the Energy Saving Tips page you can find useful information including:

    • Light colored exterior walls absorb less heat, and hence the house requires less cooling. 
    • Using air conditioners along with fans, and switching off air conditioners after 30 minutes reduces energy consumption by ACs (which consume electricity @ Rs. 10 per hour). 
    • Allowing hot foods to cool before putting them into the fridge, and not keeping liquids openly in the fridge (covering it with plates, keeping them inside sealed boxes) reduces electricity consumption by refrigerators. 
    • Setting washing machine to use cold water (instead of hot water) saves up to 90% of power.
    • Try to bring the cold items taken from refrigerator to room temperature, before putting them on the stove. Blue flame indicates efficient cooking, but yellow flame indicates inefficiency and burner needs cleaning. 
    • Try to use solar cooker/solar water heater.
    • Screensavers save the screen, not energy. Switching off the laptop when not in use is important to save energy. A flat LCD monitor/laptop is more power efficient. 
    • Ceiling fans should be mounted at least 24 inches below the ceiling for them to operate efficiently. 
    You can find many more useful tips to save energy on this page

    BEE has published an exhaustive guide on energy efficiency: Doing More With Less: A Handbook on Energy Conservation and Efficiency. You can download/read (pdf) from here.This guide contains information on energy star and labeling, energy calculation, energy efficient buildings, energy use in various sectors, etc.

    The website also has information on activities for schools and kids like painting competitions, energy club, etc. Interested schools can register themselves too. 

    While you are there, don't forget to check the Downloads section that contains a lot of downloadable information on energy efficiency, including guides and information brochures in Hindi & English, cartoons for kids, posters, handbooks on energy conservation, etc. 

    Here is the website link again: Energy Savers. Do check it out!

    Buying Solar systems using Quikr

  • Tuesday, 13 January 2015
  • by
  • Rajesh K
  • If I relocate to Bangalore (for example - it can be any other place too), how will I ensure that I get the best deal when shopping for solar systems & products?

    By using Quikr.

    Yes. You thought Quikr was only a classifieds advertising site where you can buy used products and services? No, there are many vendors there who sell new products also. It's easy to search for all types of vendors, products, and services right from the website.

    Just type 'solar' in Quikr search, and you'll find a plethora of products related to solar.

    Coming back to the topic - if I relocate to Bangalore, how will I use Quikr to get the best deal for solar products/accessories?

    Here are some interesting solar-related products/services I have identified in Bangalore, via Quikr:

    * 1BHK House with Solar Water Heater: I need a house for rent, and I need a solar water heater. Why not get both? I searched for 'Solar house with water heater' and I got this house for rent that already has a solar water heater installed.

    * Solar Panels: Next I need to buy solar panels. I searched for solar panels and I found this vendor who sells them. I'll identify other vendors too, request them to size up my requirement and suggest the capacity. After evaluating all the solar panel vendors, I'll zero-in on one, and buy solar panels from them.

    * Turnkey Solar systems: If I am not in the mood to buy solar panels, inverters, etc. from separate vendors and appoint a system integrated to install everything, I will go with a turnkey solar system provider like this. They supply solar panels, solar inverters, voltage stabilizers, UPS, etc.

    * Convert my existing non-solar UPS into Solar UPS: If I already have a UPS, I would prefer to convert that into a Solar UPS instead of buying a new one. Here's one vendor who will help me do just that.

    * Solar Lighting Systems: If lights are not already installed in the house or if I need some additional lights, I will prefer to buy LED lights that utilize less power, have long life, lower thermal output, etc. I will buy LED lights from a vendor like this.

    * Solar Chargers & Solar Kit: How can I claim to go green if I keep charging my mobile devices using the grid power? I can buy solar mobile charging kit with a small solar panel, chargers, etc. from a vendor like this.

    * Solar Water Pump: Water pumps can be operated through solar energy. So why not buy solar water pumps system and use it when I am there? I can buy solar water pumps from a vendor like this.

    You'll be amazed at how many sellers (both for new and used solar products) I was able to identify through Quikr. Of course, I need to do proper research and vendor evaluation before I decide to buy products from any of them.

    I just typed solar in the Quikr search and was able to identify all the above products within the first two pages. If I search a little more, I am sure I'll find many more solar-related products.

    If you live in Bangalore or are planning to move to Bangalore, check out the products and vendors listed in Quikr.

    Disclaimer: This post has been written for an indiBlogger contest in association with Quikr.

    Solar Water Purification RO/UF Systems by Jackson in India

  • by
  • Rajesh K
  • Solar power is abundantly available in India. So why not use that for water purification, especially in areas where electricity is not available, or in remote areas? 

    When I attended the RENERGY 2014 in Chennai, I came across the solar water purification system (using Reverse Osmosis and Ultra Filteration technologies) manufactured by Jackson Power. These systems can cater to the drinking water requirements of 3-4 families on a daily basis, according to their website. They use solar panels to filter the water, hence external electrical connection may not be required.

    I think this is a good application of solar energy, especially for a country like India which needs water purification systems in rural areas where electricity is not available or is not regular. Only, if these systems become affordable (due to mass adoption), we can have many such solar water purification systems deployed across the country. 

    Have a look at the details of their solar water purification systems from here. The brochure is here.

    This blog post is just for your information, and is not a recommendation. We don't have any affiliation with the vendors/products mentioned here. People are requested to do ample research before deciding to buy any product or service.

    Ather Energy: The Tesla of India?

  • by
  • Rajesh K
  • Ather Energy has created a lot of excitement in the recent days by obtaining funding from the Co-Founders of Flipkart for their revolutionary electric vehicle start up company, based out of the Incubation Cell, IIT Madras. 

    They want to build the best scooter, not just the best electric scooter, and they are designing electric scooters from scratch by developing their own chassis, suspensions, battery technology, etc. (According to their website.)

    One look at their conceptual electric scooter, and I am already excited. Have a look at the features for yourselves from here. While you are on their website, you can also sign up to be intimated for a test drive (whenever the vehicle becomes available) if you live in Chennai/Bangalore. So go ahead, and register your name. 

    I hope the future of automobiles in India will be oil-free, and I hope we move towards that vision quickly. But that can happen only if innovators and manufacturers bring interesting vehicles and support system to the market, and customers encourage them by buying. Government is already encouraging electric vehicles with a lot of investment plans.

    The best thing about electric vehicles is: They can be charged using Solar Panels directly. It's possible to have a solar shed at home (like Mahindra e20) or it's even possible to put a solar panel directly on the roof of the bike/scooter. Not only can the scooter supplement its energy, but the commuter below can be protected from sun, rain, etc. WIN-WIN :D

    At the least, all of us can spread the news. Go share the link of Ather Energy on your Facebook wall, NOW :)

    Why Not Live in Beautiful Tiny Houses in India?

  • Tuesday, 30 December 2014
  • by
  • Rajesh K

  • Tiny Houses are that - TINY! There is a revolution of tiny homes going on around the world, but in India, since many people are already living in tiny houses, maybe it's not as telling!

    The reason why tiny houses click is not because they are small or are cheap (although they are). But because they can be designed beautifully and they will stand out from all those larger houses and apartments coming often by the dozen. Of course, it's easy to power tiny houses using solar panels or micro wind turbines, as it consumes lesser power.

    Tiny houses don't mean a compromise in luxury, as some people think. You can have all luxurious elements within a small house. In fact, designing such a small house might take more effort than designing a larger home with standard components, and hence encourages DIY culture. Besides, one is not struck in life-long loans or unnecessary items cluttering one's life.

    Have a look at this tiny house constructed in Portland:
    Tiny house, Portland
    Tiny house interior, Portland
    Or take a look at this tiny house with wheels built out of an old van:
    Tiny houses are not only beautiful, elegant, compact and different, but come with a number of advantages over larger houses. Some are,
    • Low cost of construction, less tax, less land required.
    • Low maintenance cost, low electrical cost, low water consumption, etc.
    • Takes less time to clean and maintain.
    • Some are mobile and can be easily moved.
    • Discourages unnecessary buying of furniture and appliances. Forces one to buy only essential items.
    • Encourages better inter-personal relationship and communication.
    • Can be better designed with more luxury, at a lower cost.
    • Encourages people to spend more time on leisure activities than work, as there is no big house loan to pay off. That also keeps many lifestyle ailments away.
    • Can be powered with renewable energy more easily (solar, micro-wind, geothermal) as the power requirements are less.
    So why don't you consider building a beautiful luxurious small home in India? Tiny homes mean freedom in every sense :)

    Solar-powered Beach House in Kerala, India: Marari Villas Bougainvillea

  • Wednesday, 17 December 2014
  • by
  • Rajesh K

  • Marari Villas Bougainvillea is a solar-powered beach house/villa in the South Indian state of Kerala, known for its beaches, rivers, backwaters & coconut trees. The two-bedroom villa with a lounge & garden is equipped with many modern amenities and services, while retaining the traditional Indian architecture. As this property is located next to a beach, guests can enjoy beach view from within the rooms.

    The best thing about this villa, located in a small village in central Kerala, near Aleppy and Cochin, is it is completely off-grid and it uses solar power for electricity and hot water. I hope more tourist homes/properties adopt solar energy for their needs and stay completely off the grid, especially those in remote locations. 

    You can know more about Marari Villas Bougainvillea from their website. Don't forget to see the stunning 360 Degree tour/view of the property from here.

  • Rajesh K
  • You can always buy solar panels for your home, generate electricity using them, and become carbon neutral. But, when you travel, there is a good chance that you are still using electricity generated by polluting conventional energy sources. Is there something you can do about it? Yes. 

    Airbnb is a website that allows any private property owner to list their spare rooms, spare homes, guest houses, villas, etc. Travelers can search for homes in their destination and book any, if they find them interesting. 

    The best thing about this site is, there are some interesting and unique properties listed there. I searched for solar homes, and found the following results quite interesting. So now, even while traveling, you can remain carbon neutral by searching for solar homes in this site, specific to your destination!

    This solar home is in walking distance from Kansas medical center. It is fitted with solar panels almost throughout the roof, and solar energy is the predominant way used by this home to generate electricity. They run air conditioning, TV, Internet, Heating, etc. using solar energy. 

    Located among the hills in a rural location 50 KM away from Koln/Bonn in Germany, this house is also powered by solar panels. They say that their house produces more energy than they consume, and hence it is a carbon positive home! It's a high-tec plus energy home. 

    This house, located among the hills and a river in Spain is off-grid. That means, there is no electricity connection to the mains and hence it is entirely powered by solar energy. They also have a dry compostable toilet next to the house, and organic farm around it. The communal car parking is 500 meters below the hill. 

    This independent house located in Charlottesville, USA is powered by solar panels, has good insulation, uses ambient natural light to light up the home in the morning, and uses energy efficient LED lamps. What a better way to save and optimize energy use, than by reducing the energy required for lighting? 

    Kodaikkanal (or Kodai) is a cool hill station located in the state of Tamil Nadu, South India. In the midst of hills, amidst a water fall and stream, within an organic farm, is located this large 80 sq. meter home that is powered entirely using solar and hydro power sources. You can also get organic milk in this place, and the market in Kodai (12 KM away, accessible by jeep) sells organic produce. 

    So are you inspired to live in a solar home during your travels? Just visit Airbnb website and search for a solar home near your preferred location. Also, if you register using the above link, you'll get a credit of Rs. 1500/- which will be automatically deducted from your bill amount, when you book a property for more than Rs. 5000/- on their site. Go ahead, and stay in Solar-powered homes!

    Let's Raise Our Voice Against Dirty Power #AbMontuBolega

  • Friday, 28 November 2014

  • 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!

    What I want in my Dream Home: Geothermal System

  • Tuesday, 18 November 2014
  • by
  • Rajesh K

  • PORCELANOSA is a Spanish group with eight companies manufacturing a wide range of products including kitchen/bathroom equipment and state-of-the-art building solutions. Their products are available in more than 100 countries around the world.
    In this post, I'd like to share the product/solution from PORCELANOSA I want in my dream home -
    Geothermal Energy System
    The temperature 6-10 feet inside the earth, below our houses, remains constant irrespective of whether the season outside is summer or winter. In winter, the temperature below the earth is hotter than outside and in summer, it is cooler. This temperature difference can be used to provide heating and cooling (to power HVAC systems) throughout the year using geothermal energy.
    In this system, water is sent into the ground through pipes and is pumped up. In winter, the water coming from the ground will be hotter and is run through a heat exchanger to deposit heat, which is distributed to HVAC systems for heating. In summer, the reverse process happens: the excessive heat in the house is absorbed by the water, and is deposited into the ground where the temperature is lower. Thus, the geothermal HVAC systems can heat/cool the house during winter/summer, respectively. 
    Geothermal systems are a form of renewable energy. Even though they consume some electricity for the operation of the pump, etc. they produce 4-6 times more electricity (or save that much). They don't pollute, they are not noisy, they use renewable source of energy that is available just below the earth almost throughout the earth.
    A geothermal system has three components: heat pump, heat exchange medium (water), air delivery through ducts. Some electricity is used to power these components, but 5-6 times more energy is produced by the system.
    Geothermal systems are somewhat expensive (per kWh) when compared to other renewable energy technologies, but they last for multiple generations if installed and maintained properly. These systems can be installed anywhere, even in places where there is not much open land, as vertical pipes can be used instead of horizontal pipes for creating the earth loop. And since these pipes are buried into the ground, the real-estate space on the ground is not wasted.
    The same system can be used for both heating and cooling, and that's a big advantage. Water is used as a refrigerant, but it is recycled after use - hence not wasted. One system can be used to heat/cool multiple systems simultaneously if the installed capacity is sufficient.
    Geothermal systems are a mature technology and have been in use for more than 60 years in residential applications. They are also used for large-scale commercial power generation, but that's a different system. They don't generate any noise and save a lot of electricity. They use the earth's heat that is always available, everywhere.

    Why not Build Toilets powered by Renewable Energy?

  • by
  • Rajesh K

  • Toilets are vital to any home. But what happens to all the output that go via drainage pipes? Aren't they let out into the water bodies or sea? Is that the best way to manage our waste?
    India still has 597 million people defecating in the open. But the waste generated by them, when let out on the earth decomposes and even provides manure for plants to grow.
    So which system is better? Having toilets and polluting water bodies, or not having toilets and defecating in the open?
    The problem with cities is: There is no space or free land where human waste can be left to decomposed. The problem with villages is: There is not enough resources to build toilets and maintain them.  There is also another problem: The perennial shortage of water.
    These problems can be tackled effectively with one solution: Renewable Energy-based toilets that recycle urine/feces to create manure (reducing waste at source), and automatically release the optimum water after every use to utilize just the right amount of water that is needed.
    Renewable Energy-based toilets exist today: Have a look at this and this. I also saw a compostable toilet designed and sold by The Rain Center, Chennai.
    So, at least in outskirts of the cities (where there is no drainage facilities) and in small towns/rural areas, why not build renewable energy-powered toilets that can save water and create manure (thereby reducing waste that clogs pipelines and waterways)? We should look at implementing this either through private initiative or government supported schemes in India.
    Domex, a popular brand in toilet cleaning solutions, has come up with an interesting campaign called - 'Toilet for Babli'. Since open defecation and poor cleaning are known to cause diseases, and since people (especially women) need a toilet right in their homes/near their homes in order to be able to use it at any time,  it's important to make villages open-defecation free.
    You can bring about the change in the lives of millions of kids, thereby showing your support for the Domex Initiative. All you need to do is “click” on the “Contribute Tab” on www.domex.in and Domex will contribute Rs.5 on your behalf to eradicate open defecation, thereby helping kids like Babli live a dignified life.
    It's good to note that corporate companies are pitching in for building more toilets in India. It will be better if they insist that their contributions are used to create renewable energy-based toilets, so that they are used effectively, and become sustainable and useful on the long run. Another advantage is, once installed, solar panels/concentrators can power these toilets for more than 25 years without additional cost. The maintenance is also minimum. 
    Clean energy for clean toilets. Don't you think that's a great idea? Do visit the Domex web-page link given above and click on the contribute button. Your clicks and shares can make a difference to many people without toilet facilities.
    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?
