Wounded Earth - Effects of Air Pollution

By Seetha Anand | Feb 07, 2019 | 0 Comments

Air pollution is not merely a threat to our health but a reminder that our most celebrated technological achievements are in fact environmental failures. Be it automobiles or jet planes or power plants, they are all guzzling down precious fossil fuels. Some ways to reduce pollution include energy conservation, switching to renewables, and following the principles of reduce, reuse and recycle.

Labour Care = The Human Factor

By Dr. Shashi K | APR 11, 2019 | 0 Comments

Our urban scene anywhere in India appears like a permanent construction site. All along the construction sites, the lesser privileged live in temporary accommodations. Most of these people are the victims of the vagaries of the weather or early victims of climate change related droughts who come to cities for some opportunities. Labor care therefore is one of the most important considerations that we as a construction firm are completely committed to.

Which Electric Vehicles Are Available In India

Diesel, Petrol, or Electric Vehicle: How Can I Decide Which Is Best For Me?

By Dr Shashi K | Apr 4, 2019 | 0 Comments

Electric vehicle has been a human fancy for a long time. However, never before the urgency to have electric vehicles as mainstream vehicle had been more than in recent times. This is particularly significant as electric vehicles are clean energy vehicles and something that can help wean us away from our fossil fuel addiction. Electric vehicles are also non-polluting and will propel urban ecosystems to become cleaner and better.

Why Should We Use Star Rated Appliances?

By Dr. Shashi K | Mar 28, 2019 | 0 Comments

A higher star rated appliance will assure you save money for the life of the appliance. A monthly saving of just 200 units would put Rs.1,700 in your pocket at current electricity rates. Over ten years this means Rs.2,04,000 and over 25 years this means Rs. 5,10,000, factor in this cost when you buy a new appliance. While earlier it was difficult to understand the energy efficiency quotient of appliances, now the star ratings helps us understand the potential of savings directly.

Why is it important for everyone to know about Biodiversity-1

Biodiversity Loss and What We Can Do About It?

By Dr Shashi K | Mar 21, 2019 | 0 Comments

We are losing some of our unique ecological niches because of the direct and indirect disturbances that we humans create in our ecosystem. As a result of the changes in land use, pollution, global warming, and physical destruction of ecosystems, species are getting extinct. Although extinction of species is a natural Darwinian process, the rate at which the species are getting extinct now is unprecedented. It is entirely possible to stop the accelerated loss of biodiversity by making changes in our life-style. And it’s all……… worth it.    

Why Is Renewable Energy Important? Types of Renewables

By Dr. Shashi K | Mar 14, 2019 | 0 Comments

Nothing, perhaps nothing else that matters so much is more appropriately named than how energy is classified. Embedded in the name of renewables is the core of what renewable energy delivers. It is the form of energy that can be renewed endlessly as it makes use of the resources that are a part and parcel of the Earth’s natural system, be it oceans and tides, water, wind, sunlight and even accessible heat energy stored in the Earth.

INDOOR AIR QUALITY(1)-1

Indoor Air Quality

By Dr Shashi K | Mar 07, 2019 | 0 Comments

Indoor air quality is mostly an undervalued asset as there is very little awareness about its correlation with overall health and well-being. Outdoor quality contributes to it to some extent, but many indoor air pollutants are not really suspected as cause of pollution that can be harmful to humans. Biological, chemical and particle pollution can create significant distress to all humans especially most vulnerable sections of the society just as newly born babies and old people. 

Organic Gardening - Vertical, Terrace, and Regular Gardens

By Dr. Shashi K | Feb 28, 2019 | 0 Comments

Gardening offers some less visible, but equally sustaining benefits - whether it is a vertical garden, a kitchen garden, a backyard garden or a roof-top garden. Home gardening helps close the loop from organic waste to compost to growing vegetables. It not only helps in reducing the heat gain on the roof/terrace and other areas at home but also contributes to enriched soil and reduced landfill waste. Besides, eating fresh fruits and vegetables immediately after harvesting assures high level of nutrition and satisfaction.

What is Wrong with the Conventional Water Treatment Options: What are the Alternatives?

By Dr Shashi K | Feb 21, 2019 | 0 Comments

Waste water treatment has traditionally been the responsibility of municipal corporations, but due to water scarcity it is now mandatory for industrial and residential developments to treat sewage before releasing it. Conventional treatment of grey water requires oxygenation, which is energy consuming and generates large amounts of sludge that needs responsible disposing. On the other hand, a plant-based system (Phytorid) is a tried and tested technology that achieves the same results at minimal cost without expending energy or using harmful chemicals.

Is Solar PV A Feasible Solution For Our Power Needs?

By Dr. Shashi K | Feb 14, 2019 | 0 Comments

Reduce or eliminate energy bills. Earn tax credits and rebates. Start savings from Day 1. Help the environment and help us all. Solar power systems derive clean, pure energy from the sun. Installing solar panels at home helps combat greenhouse gas emissions and reduces our collective dependence on fossil fuel. Traditional electricity is sourced from fossil fuels such as coal and natural gas. For a country with abundant sunshine and poor connectivity, using solar power to generate electricity clearly appears to be the way to go!

Vegan Options in the City of Hyderabad

By Seetha Anand | Nov 28, 2018 | 0 Comments

Veganism is slowly but surely catching up in the city of Hyderabad. A vegan diet means no dairy, eggs, honey, meat, poultry or fish -- abstinence from all animal products. People turn vegans for reasons of health, prevention of animal cruelty and for environmental protection.

Is Solar PV A Feasible Solution For Our Power Needs?

Feb 14, 2019 10:44:23 AM / by Dr Shashi K

Have you looked at a solar powered calculator, watch, or toy and wondered why more things in your house aren’t solar powered? If you have, you’re not alone. For a country with abundant sunshine and poor connectivity, using solar power to generate electricity for local needs (also called decentralized power generation) clearly appears to be the way to go!

Is solar PV a feasible solution for our power need-1

Like 70 percent of Indians, you probably are already connected to the electricity grid, making you wonder if it makes sense to switch to solar. Well, read on to understand why!

 

What is Solar PV?

What is solar PV-1

 

Simply put, a solar PV absorbs sun’s energy, converts it into electricity, and transmits it either for storage or distribution, depending on the equipment used.

The panels absorb sun’s energy and convert it into direct current (DC), which is then transmitted to a convertor. The convertor changes it to alternating current (AC) and sends it to the transmitter for being used in the building, or to a battery for storage and later use.

How Much Does It Cost?

 How much does it cost-1

The cost of a solar PV system depends on the type of panels used, the area covered, the technology used, etc. Traditionally, solar cells were made of silicon. However, the material used is rapidly evolving to more easy-to-use forms, such as inks and dyes, which can be used for printing out solar cells. However, the cost is really marginal when you look at the overall cost of the home/construction.

 

How Much Electricity Will It Generate?

How much electricity will it generate-1

In India, a 1-kWp panel can produce up to 1600 kWh of electricity per year, which translates to about 4 kWh per day.

The solar PV system installed at Mittal Auriga in Bengaluru is a 1.5 kWp, which can save 60-80% of the energy bills. You can take the challenge to make more savings if you use all energy efficient equipment's and are conscious about consuming energy.

What Are The Advantages?

 

Renewable Energy

Renewable energy-1

First of all, solar energy is something that is available in abundance. It is renewable, which means we will never run out of sunlight! The regular electricity in most parts of India is generated using coal, which is limited in nature.

 

Low Carbon Emission

Low carbon emission-1

Generating 1000 kWh of electricity from solar PV reduces about 1400 pounds of carbon dioxide emissions, compared to the conventional, fossil-fuel-based methods. That is the amount of carbon dioxide you would generate if you kept your car engine running for 24 hours, non-stop! (US Department of Energy report)

 

No Pollution

No pollution-1

Thermal power plants are notorious for the pollution they cause. Hydro and nuclear power has its own downside and a potential threat for ecosystems. Compare this to solar PV generators, which have zero emissions during their operation.

 

Saves Money

Saves money-1

The main cost involved in the solar PV system is incurred during the installation, as it requires solar panels, mounting structure, inverter, batteries, cables for connection to the grid, etc. But once this is done, the amount of money you would save by generating your own electricity is enormous. Once you purchase a home with solar power installed, you can just celebrate for the savings you are going to have month on month. If you are renting a home with solar rooftop installation in place, be glad that your electricity bills will be almost negligible.

 

Has It Been Successfully Used Anywhere in India?

Has it been successfully used anywhere in India

India is on its way to becoming the second largest market for solar energy in the world, with 113 GW of harnessed energy, which is higher than that of the U.S.! While most of these are commercial scale projects spread over thousands of acres, like the Kamuthi Solar Park in Tamil Nadu or the Charanka Solar Park in Gujarat or the Kurnool Solar Park in Andhra Pradesh, residential solar projects are also catching up, as the annual rooftop solar installations in 2017 alone were more than the total systems installed from 2013 to 2016!

 

What is The Maintenance Required?

What is the maintenance required-1

The main maintenance required for a solar PV system is to clean the dust collected on the panels and the inverter periodically. The frequency of cleaning can vary from once in 3 to 12 months.

 

Will it Change The Look of My House?

Will it change the look of my house-1

Most solar panels in residential complexes are placed on the roof to maximize the sunlight available to it. Therefore, chances are, you will not even be able to see the panels from your apartment, villament or villa. Even if you do, the sleek panels will only enhance the look of the complex, and will hopefully encourage your neighbors’ to become more environment conscious!

 

Will I Still be Able to Connect to the Regular Grid Also?

Will I still be able to connect to the regular grid also-1

Yes, you will! This is probably the best part of going solar in India. You will be connected to the grid for electricity supply during the night and on cloudy days. Being connected to the grid also means that when the electricity generated during the day is more than the electricity consumed, it will go back to the grid, which essentially means they are buying the electricity from you. The way this works is that they charge you for the electricity you consumed minus the electricity you sent back to the grid. This is called net metering.

 

What If There is Excess Electricity? Can I Store it for Later Use?

What if there is excess electricity-1

Absolutely! A few years back the excess electricity generated from solar PVs would be wasted, as there was no technology to store it. But with the advent of technology, batteries have been developed that can store the excess electricity for later use. In addition, you also have the option of selling your excess electricity back to the regular grid.

 

What if it is Cloudy?

It goes without saying that shade and clouds do not bode well for a solar PV system, which is why it is a good idea to be connected to the regular grid. However, with the number of sunny days in India, you will probably end up generating enough electricity to cover the few cloudy days.
