It's a worthy goal to at least attempt to complete our transition to a Type I civilization and begin work on Type II, the line is probably quite blurry since any type of space exploitation moves you towards II but is quite possible before completing I. I don't doubt the validity of Jevon's paradox but I think it's implications are not negative. From Wikipedia's article on it " increased the efficiency of coal use led to the increased consumption of coal in a wide range of industries" the key point there is that the increased consumption came from a wider application of the technology in areas where it was not able to be used before. This led to higher output and innovation in those industries which further accelerated the industrial revolution. A modern example would be Moore's law which has improved efficiency in transistor production, spreading the technology to almost every other industry resulting in further increases in efficiency and many revolutions and breakthroughs.
