This might be something that the big tea producers in India might want to look at - Tata, are you listening? Green Daily has this bit about Traditional Medicinals, a California based business who have bought enough solar panels to power 75% of their tea processing plant: http://www.greendaily.com/2008/10/01/traditional-medicinals-opens-worlds-largest-solar-powered-tea-f/ They plan, off course, to go entirely off-grid and convert it to 100% solar power in the very near future.
I think this would also be a good idea for others in this business in India including A V Thomas, Girnar, Kannan Devan etc. Considering how globally competitive the tea business has become, the sooner the Indians start portraying a green image as one more advantage that they can offer, the better it will be for them. Let's hope that this happens asap.
