One of the biggest concerns about changing to a green lifestyle is, of course, financial. How much does it cost to switch to a green lifestyle?
There is a perception that all of this must be very expensive, and that only altruists and tree-huggers can afford to live this kind of lifestyle. But a green lifestyle needs to be sustainable in all ways.
Something that is more expensive than its alternative will usually cost less in the long run. This is what makes evaluation of green products and green building materials so difficult. But looking at the life-cycle cost (the cost not just of purchasing the item, but also its operation and maintenance over its useful life) can show that the overall cost of the green option is usually lower.
