Charging batteries is almost free, really. You can make a good case for cordless tools if they are used regularly, one or more times a week. That's just not me in my current life though.
Energy is energy. It takes a certain amount of energy to turn a drill bit or a sawblade. Converting line voltage AC to stored low-voltage DC to do the same task isn't "free".
Batteries are only good for "x" number of cycles before they die and have to be replaced. The replacement cost is exponentially higher than the cost of the line voltage energy they replaced. Seems to me that bare cordless tool costs are fairly similar to their corded cousins, so battery lifecycle costs are the wildcard in the equation.
Cordless is great for convenience, but it seems they are much more costly over the life of the tool/batteries (especially when multiple batteries are required for extended operation) than using equivalent-quality corded tools.
