Milk storage unit uses sun to keep cool

Got chilled milk?______

That’s the unofficial slogan for Boston-based Promethean Power Systems, a company that this month received a grant from the National Science Foundation to further develop its innovative milk refrigeration system.

Promethean’s target market is India, though it plans to expand to Africa and Latin America as soon as February. India is the world’s largest producer and consumer of milk; the country is home to some 70 million farmers who contribute to a multibillion-dollar dairy market.

Because temperatures can reach 100 degrees during peak summer months, raw milk begins to spoil within hours of collection. And India’s frequent blackouts, due to a strained power grid, make it difficult to keep milk cold enough.

Banking on solar power

Nice ATM

Vortex Engineering, a company focused on developing sustainable products for rural India, decides to develop an ATM to meet this segment’s banking demands. The ATM is powered by solar energy consumes just 4 per cent of the total energy that is required by a conventional ATM to function. It has the capability to serve Indian villages — indicating an opportunity for over half a million ATMs across the country. Read how Vortex Engineering’s unique ATM can help deal with the problem of low banking penetration in the third of the five-part series from India Brand Equity Foundation’s Innovations from India: Harbingers of Change.

The delivery of financial services to all sections of society at an affordable cost has been an area of concern for governments around the world. Financial services include services such as credit, savings, and insurance. To date, banks have been considered the most preferred channel for providing financial services. However, the banking channel has its own limitations, especially in nations that have a large rural population and diverse geographical conditions. This results in a low concentration of banking systems in rural areas. Rural locations account for around 70 per cent of the total population of India, but have access to only 30 per cent of the total bank branches of the country. Read the rest of this entry

Bharti Airtel’s green initiative (India)

The Telecommunications sector has been an intrinsic part of India’s growth story bringing 1.2% of GDP growth with every 10% increase in mobile penetration. This brings far-reaching changes in the lives of urban and rural India by connecting them seamlessly. It is indeed interesting that in addition to urban areas almost 90% of villages today are covered by improved telecommunications. With 800 million subscribers, today one can claim that the industry is the provider of the fourth basic need after food, clothes, and shelter.

However, there stiff challenges that constraints the industry from providing access and connectivity in the remote areas. The most critical of this is unavailability or limited availability of grid power. On the other hand, the operators are required to meet minimum roll out obligations (coverage) and meet Quality of service levels (network up time) or face heavy penalties and even loss of their Licenses. To minimize environmental impact, all operators first use battery power and when these run out, switch to diesel generators which increases the cost of operation by three or four times and adds to operational complexities.

Despite all challenges and constraints, Bharti Infratel has taken proactive and bold steps to mitigate and improve operations to provide 24×7 network service uptime. Our pioneering GreenTowers P7 initiative is a comprehensive energy efficiency and alternate energy programme covering seven high impact initiatives, which are aimed at reducing diesel usage and therefore the carbon footprint.

These initiatives include:

1. Alternate energy sources like solar etc. – these are clean energy solutions and have today proven their case as a strong alternate to conventional sources of energy. Having already deployed these at around 1050 sites (inclusive of 500 nos. of Indus Towers), which has saved 6.9 mn litres of diesel and around Rs. 280 mn.

2. Energy efficiency measures like Integrated Power Management System (IPMS) and variable speed DC generators (DCDG) – this has reduced diesel consumption by 1.2 mn litres and already saved Rs. 47 mn across almost 900 sites where this has been implemented.

3. Demand side management like Free Cooling Units (FCU) instead of air conditioners etc. substantially reducing the electrical load requirement. This has already been implemented across 3400+ sites, saving consumption of 4.1 mn litres of diesel.

Bharti Infratel, today, is the only telecom tower company, which has installed almost 3 MWT of solar capacity on our network, generating more than 5 mn units of electricity every year. All this has been creditably achieved despite absence of subsidies on solar unit installations – a move contemplated widely by various agencies and the MNRE for a while now, without any significant action or policy being announced.

The GreenTowers P7 programme is scoped for 22,000 tower sites, (primarily rural areas having low or no Grid Power availability) out of which 5,500 sites have already been implemented in the first year as part of this 3-year programme. Once completed, the initiative will reduce diesel consumption by 66 mn litres per year; with a significant carbon-di-oxide reduction of around 1.5 lacs MT per year.

The project already holds the unique distinction of being one of the largest such initiatives around the world, while also having the largest green footprint in India, by any telecom tower company. Bharti Infratel bagged the 2011 ‘Green Mobile Award ‘ at the GSMA Mobile World Congress at Barcelona, and was also awarded the 2010 innovative infrastructure company of the year award, at the CNBC Infrastructure Awards, for this groundbreaking initiative.

Bharti remains the first company in the world to introduce the practice of sharing of passive infrastructure by collaborating with our competition to share mobile towers and to reduce the collective carbon footprint of the industry. This has become subject of case studies in world renowned institutions including Harvard Business School.

Within Bharti Airtel, a number of initiatives have been launched last year aiming to reduce energy consumption in lighting and air conditioning areas. The company has installed Solar Hot Water Generator at its main campus in Gurgaon for fulfilling the hot water requirement in the cafeteria. Majority of its facilities across NCR region are now installed with LES (Lighting Energy Savers), which have reduced energy consumption in the lighting system to the tune of 10-25%. Variable Frequency Drives installed in AHU (Air Handling Unit) at its Campus have helped in enhancing the efficiency of cooling system by 10%. These measures have resulted in a saving of 8.5 lakh units of electricity per year. airtel has embarked upon technology related initiatives like virtualization of servers that have helped it release over 500 CPUs. Additionally, we are now moving towards cloud based services to take virtualization to the next level.

Additionally, the drive of sending e-bills to the post-paid customers is helping save 12,840 trees annually. Within its campus, the ‘Secure Print’solution – an automated queue management based secured printing solution that has led to an annualized saving of about 8 metric tonnes of paper.
