Printer:New Clear Energy
The sun is everywhere. In India we have too much of it. Instead of sweating in it, we can try and
make the sun do some useful work like cooking food and lighting homes. On a sunny day, the
sun's energy falling on a 150-cm x 150-cm area exceeds the energy delivered by the kitchen gas
stove at full throttle! If we just collect that energy and concentrate it at one spot we'll be able to
cook without any fuel!
We are blessed with abundant sunshine, a good enough reason to seriously engage with this
perpetual, non-polluting energy source. The best minds in our country should be researching on
solar energy. They should be designing the cheapest solar cells and making the most efficient
solar cookers. 400-million Indians live without electricity. Solar energy holds the potential for
electrifying the remotest Indian hut. This will be true devolution of power and real empowerment
of our people. Gandhi's dream of “power to the people” will come true!
India has made a good beginning with wind energy. One single private company - Suzlon, alone
has installed over 6,000-Megawatts of non-polluting wind power. This happened because the
Indian government enunciated the right policies, gave the right tax breaks and provided a
conducive environment to develop wind energy. This story needs to be repeated with solar
Several sterling individuals helped me with this book. Dr. Anirban Hazra and Anish Mokashi sent
me many real and virtual books from abroad for research. Priya Kamath's initial drawings paved
the way for the book. Whenever the “sun” book came under a “cloud” my colleague Dr. Vidula
Mhaiskar found unexpected shafts of “sunshine” to brighten it.
Thanks to journalist friend Neela Sharma for discovering the young illustrator and designer -
Reshma Barve. Her deep sensitivity has imbued this book with life. I hope children enjoy this
comic book and it brings a little sunshine in their lives.
I would specially like to thank Dr. Arnab Bhattacharya, Dr. T. Sampath Kumar, Alabhya Singh,
Joyce, Nyla Coelho, Pavan Iyengar, Rajkishore and many other dear friends for critically
reviewing the manuscript and suggesting changes.
Finally, I would like to thank IUCAA - the institute which nurtured this project and the Navajibai
Ratan Tata Trust for providing the financial support for preparing this manuscript.
