"We all have to do this together," hetold the Bonnconference Too much time has been lost in sterile

debates... America itself cannot provide the solution,but there is no solution without America."

He alsothought that the development challenge wasmaking sure that developing countries have theopportunity to follow a cleaner path forward. "I liketo tell the story that earlier this decade,India had onlyabout 55million peoplewith phone service,but, ratherthan insist on following the industrialised countries'path of wired service,India leap-froggedto cell phones,with the result that a few yearslater 350million Indianshavephones.We need a similar leap-frogging of fossilfuels in the world of energy.II

Energy efficient technologiesThe problem isthat energy-efficient technologies areby no meanscost-free,and developedcountries,whichhavecausedglobal warming in the first place,haven'tput their money where their collective mouths are,despite repeated promises to this effect. In Bonn,

Dutch company which designed this LED bulb.

"The engineering and manufacturing of this bulb hasbeen carried out in India, and it is estimated that if all

Indians were to replace one incandescent bulb withthis bulb, it would save 56 billion kWh of electricity,and 44 million tonnes of

DrMathur told that while

the capital cost of thePharox bulb was high, ithad a five-year warranty.It had a life of 50,000 hours,

as against a lifeof onlyafifth of this for a CFL.Even

CFL bulbs had cost Rs.1000

when they were first introduced. The glass bulb hasbeen manufactured in Firozabad,which isa traditionalglassindustrycentre. Suchtechnologycouldearn carboncredits because of its low consumptionof energy.

India'sinnovationcentres were requiredfor developingsuch products and also marketing them - virtuallycreating markets in some instances.The ElectricityActdidn't permit private operators to generate power butthere was a huge opportunity for decentralised energysystemsto provide electricityand cookingfuel to some700 millionIndianswho had to make do without these

two basicnecessities.Forcooking fuel, biomass,whichis widelyavailablein rural areas, would be energy-efficient and received a 60 per cent subsidy

Rain water harvestingAt the house-warming ceremony in his new home, DrSreepathipresentedallthe guestswith a speciallywrittenbooklet about roof water harvesting. He had decided,during construction, that he would harvest the rainfallingon hisroof,choosingthis optionfirst,and diggingan open well only later. And having made his choice,he decided he would teach others about it too.

The 'new type house' attracts manyvisitors.Everyweek2-3 people come to have a look at it. "Though thereare water shortages, very few people get convincedabout rainwater harvesting. One major mental blockis about the potability of stored rain water. Theimpression isthat the tap water is best."

In DrSreepathi's locality,houses don't have municipalwater supply. Not a single open well here has water.The number of bore wells is increasing. Though theyhave Sreepathi's liveexample nearby,they don't mindwaiting for hours in queues for the tanker water thanindependently tapping the rain. Recently,as a resultof Sreepathi's constant encouragement, two familieshave now started utilisingrain. "Inthe entire city,onlyabout 35 families that are harvesting rain", tellsSreepathi with disappointment, "Exceptthese examples,the city is far far behind in water literacy."

the cities. This disappear-ance of the common house

'.1 sparrow from the urb~n,~ areas isnot something new,

nor is it restricted by polit-ical boundaries. But re-

sponses to this disappear-ance have been quitemuted in India, unlike

elsewhere. A few years ago,it rang quite some alarm bells in Europewhen thepopulation of sparrows fell drastically, by up to 85 percent, in London. On the other hand, in India, thephenomenon has hardly ruffled a feather, apart fromconcernsraised in the scientificcommunityand amongnaturalists

DenisSummers-Smith's(recognised as a world experton sparrows) theory was that the unleaded fuel,believed to be eco-friendly, had harmful byproducts.The fuel uses MethylTertiaryButylEther (MTBE)as ananti-knocking agent. Along with byproducts ofcombustion,this killssmall insects.The insecticidalnature of the byproductsmakesthe food for thosebirds feeding on insects scarce. Though adult sparrows

can survivewithout insectsin their diet, they needthem to feed their young.Withfewer insectsto feedon, the infant mortality rates of sparrowwent up.

Unleaded petrol is not the only culprit. In nature there

can be multiple causes to a problem. The change inlifestyle of human beings is a significant factor,potentially.
