It was a 4:30am wake-up call on a cold morning in Delhi for my flight to Lucknow. I stepped into the shower… only to find cold water. Not the best start of a day I have had!
When I got back from my trip a few days later, I asked the building manager why there had been no hot water at that time. “Sir” he said, “it is solar; 4:30 is too early!"
I had to think about that for a while. Different perspectives raced through my mind: First, I thought it was great that the water heating was solar and thus running on clean energy. After that, I thought that it was a real pity we do not know how to store solar energy so that we could still have hot water at 4:30 in the morning. After that again, I actually felt it was perfectly OK not to have hot water at 4:30 in the morning: we will not be able to solve our energy problems without some compromises for those of us who have hot water at all. And that brought me to the most important realization: millions and millions of people were waking up at the same time as I did, but theirs was a dark winter morning because they do not have electricity to turn on a light bulb, let alone get hot water for a bath.
