Present-valued at a societal 3%/r real discount rate, an investment of $284 billion is required to adopt present and emerging technologies. The return would be more than $949 billion in 2010 present value.
Naturally, the required investment and expected benefits shrinks at very high discount rates. However, this sensitivity test applies only to the present-valuing of the streams of investments and returns: All technologies assumed meet a 12%/y real hurdle rate.
