The festival of Diwali happens in India every year and people everywhere put up lights and it is considered beautiful and the same happens in the West starting a week from now till the end of December. Why on one hand we teach our kids to conserve energy and on the other hand we are so wasteful about it? Why do we add to pollution just because it is a tradition?
WHY WHY WHY WHY WHY?
Go on and tell me the reasons for your choice in light of global warming and waste of resources.
"In order to do an apples-to-apples comparison, let's pit the Prius against a car that's frequently cited as its closest nonhybrid equivalent in terms of weight, size, and other specs: the Toyota Corolla. Would it be more energy-efficient to buy a brand-new Prius or someone else's old Corolla? Since certified, pre-owned cars tend to be less than five years old and are refurbished before going on sale, let's generously assume that your used Corolla will last exactly as long as your new Prius: 11.5 years, or 172,500 miles. (The average American discards a car every eight years, but that's more often than necessary: A well-made vehicle will typically last 15 years.)
According to the federal government's 2008 fuel economy guide (PDF), a Prius averages 46.5 miles per gallon (assuming half of a driver's time is spent on city streets and half on the highway). Beyond 172,500 miles, then, the Prius will consume 3,710 gallons of gas. Each gallon contains approximately 124,000 BTUs of energy, so that translates into 460 million BTUs' worth of burned fuel. Add in the production energy, and the new Prius is responsible for a grand total of 573 million BTUs over its lifetime (not including disposal costs).
A Corolla with an automatic transmission, by contrast, averages 30.5 mpg—more than eight miles per gallon better than the average car on America's roads. Over the vehicle's lifetime, that translates into 5,656 gallons of gas containing more than 701 million BTUs of energy. Since the Corolla we're considering is used, we won't add to that total by factoring in production energy." - www.slate.com

I failed to take what into account?
Even the article in Wired, which seems to be main competing source of information, uses the figure of 113 million BTUs as a production figure. Also - these figures are more than two years old. The technology for producing such a car has improved greatly in the last two years, especially once you factor in the economies of scale that a good uptake of the product will engender.
I live in an apartment, so I never put lights up outside. Although, I cannot imagine that if I lived in a house I'd be too awful thrilled at the idea of climbing up a ladder with a string of lights slung over my shoulder and a staplegun in hand. No - definitely not my idea of a good time. And then, I'd probably forget to turn them on anyway! lol I'll keep the lights on the tree, where I can get to them and the plugs easily.
