RETREAT (Resource-Efficient TERI Retreat for Environmental Awareness and Training) - a self-contained island. The building employs an array of techniques – a ‘combination of modern science and traditional knowledge’ – including solar chimneys and earth air tunnels, fully integrated solar photovoltaic systems, water recycling, and a gasifier that uses firewood, dried leaves and twigs, and similar waste material to achieve not only considerable savings in energy consumption but also to reduce its ‘ecological footprint’. Here are a few more details and highlights of the innovations.

Solar water heaters  Twenty-four solar water-heating panels provide up to 2000 litres of hot (65 °C) water every day.  Integrated photovoltaic systems  The energy captured by the photovoltaic panels is fed into a battery bank, which is the main source of power at night. A number of panels, each measuring 1.1 by 1.2 metres, are joined and form an integral part of the roof of the building. The panels can generate up to 10.7 kilowatts peak of energy, which is fed into a 900 ampere-hour/240 volt battery bank.

Biomass gasifier  Firewood, dried leaves and twigs, the stubble left in the field after a crop is harvested, and such other forms of biomass fuel the 50-kilowatt gasifier, which is the source of power for the building during the day. The gasifier runs a generator, the diesel requirements of which have been cut down to 30% after appropriate modifications; the rest of the fuel comes from the gasifier in the form of ‘producer gas’. One unit of electricity produced needs 1 kilogram of biomass and 90 millilitre of diesel.

Subterranean air tunnels  Effective insulation, shade provided by trees, and a network of underground earth air tunnels circulating cool subterranean air throughout the residential block ensure that the temperature in the complex remains more or less even all year round. The system has been augmented by adding chillers for dehumidification and additional cooling during rainy days. Daylighting  Specially designed skylights, energy-efficient lights, and a sophisticated system of monitoring and controlling the consumption of electricity illuminate the complex. The conference rooms enjoy glare-free daylight through strategically placed skylights. A master control system switches off the lights automatically whenever it senses that daylight alone is enough to maintain the desired level of illumination. In the living rooms, strategically placed light points and specially designed swivels make it possible to use the light at a study table as well as for bedside reading.

Recycling waste water  A bed of reed plants (Phragmites) clarifies 5000 litres of water from the toilets and kitchen every day; the recycled water is used for irrigation. Sewage is collected initially in a settling tank (an Imhoff tank) that allows sludge to settle to the bottom. Part of the waste is decomposed at this stage by microbes. Then, the water is passed through a bed of soil, which also supports specially selected reeds well adapted to waterlogged soils. The roots of these plants act as living filters: they absorb and remove many of the toxic substances from waste water.

Building new wind capacity is crucial in the fight against climate change
Ecotricity is building new turbines to make clean electricity to replace the conventional polluting sources that cause climate change. Every unit of green electricity from wind power replaces one unit of electricity normally generated from conventional polluting sources such as coal.

Wind is a sustainable fuel source that doesn't produce pollutants of any kind and its energy can be harnessed without causing any damage to the environment. The energy used in manufacturing and erecting a wind turbine is paid back in the first 3 to 6 months of operation. At the end of a wind turbine's lifetime, typically 30 years, it can be removed, leaving behind no lasting legacy. Please visit Ecotricity website for more information:

There’s good reason entire countries have begun to contemplate outlawing the incandescent bulb.  About 90% of the energy required to light an incandescent bulb is completely wasted as heat!  The incandescent bulb is, in many ways, a technological relic from the age of Thomas Edison (circa 1880!).

CFL bulbs offer a great solution that is available today.  CFLs use about 75% less energy than incandescent lights for the same light output.  Overall, CFLs are one of the easiest and most effective ways to reduce energy use in your home. CFL bulbs also last up to 10 times longer than incandescent bulbs.   In the lifespan of one CFL, you could end up changing 10 incandescent lights.  That means 9 fewer trips to the store and 9 fewer climbs up onto a chair to replace bulbs in hard-to-reach overhead fixtures.

With a biodiesel processor, you don't have to be a plumber or mechanic to make your own biodiesel. This is not a hobby kit but a complete system engineered with quality materials. You get all the specialized equipment and supplies you need to start making biodiesel that same day. All you need to add is vegetable oil, methanol, electricity, and tap water. The whole setup fits comfortably in the corner of your garage. This is a "closed" system, so it won’t smell, and you won't have to pour or stir any liquids. It will turn even heavily used cooking oil into clean burning, biodegradable, and smooth-running biodiesel. Whatever you own that runs on diesel fuel you can power with the biodiesel you produce with your own biodiesel production system. 

It produces approximately 40 gallons of biodiesel every 48 hours, with about one hour of operator time required per batch. Supplies typically cost 70 cents per gallon or less.



Building energy modeling is an efficient and effective way to determine which combination of strategies and equipment is the best fit for a particular project. These computer programs allow 'green building professionals' to model a variety of energy consuming systems and scenarios and compare the energy loads and costs to optimize the energy efficiency of the building.

US DOE - EnergyPlus
EnergyPlus models heating, cooling, lighting, ventilating, and other energy flows as well as water in buildings. While originally based on the most popular features and capabilities of BLAST and DOE-2, EnergyPlus includes many innovative simulation capabilities such as time steps of less than an hour, modular systems and plant integrated with heat balance-based zone simulation, multizone air flow, thermal comfort, water use, natural ventilation, and photovoltaic systems.

The Taj Mahal is ill and could be slowly dying.

India's most famous monument, which is in the running to be voted as one of the seven new Wonders of the World, flanks a stinking, garbage-infested river and is almost always enveloped by dust and smog from belching smokestacks and vehicles.

Millions of Indians hope the majestic white marble mausoleum, which took 17 years and 20,000 workers to build, will feature on the Wonders list, but conservationists and environmentalists are urging people to pay attention to its darker side.

"If things continue like this, the Taj Mahal's age will decrease, like that of a diseased man," said KS Rana, a leading campaigner for saving the Taj, located in Agra, a four-hour drive from New Delhi.



The community kitchen in the Golden Temple complex, the holiest of holy Sikh shrines at Amritsar, uses solar energy for its community kitchen says a report in the Indian Express. The Union Ministry of Non-Conventional Energy has asked the Punjab Energy Development Agency (PEDA) to prepare a detailed project report for the purpose.

The solar cooking system, set-up at a cost of Rs.1 crore has the capacity to cook for 30,000 persons everyday, the biggest of its kind in the country.

On any given day, hundreds of people eat the langar at the Golden Temple complex and the number multiplies during festivals.

Earlier, the langar was cooked using gas and wood as fuel. According to PEDA executive director Jagjit Puri, the project involves the use of German technology. The solar panels have been installed on the roofs of big buildings in the complex, including Teja Singh Samundari Hall and Guru Nanak Niwas and other serai's. Solar energy is transmitted to the main kitchen from these panels. The panels has been mounted on a rotor to face the sun.

The Golden Temple complex langar serves food to about 1,000 persons at a time and is closed late at night
