The problems with cost plus contracts for energy has been one Ive battled since 1975, but not had much success. While it is necessary to build energy cost adjustment factors into long term contracts, there are several ways those contracts can be structured to prevent them from being an energy wasting loophole but it would require contract officers to understand what theyre buying and that just doesnt seem to be happening.drbill:Back in the 70's I was the energy conservation officer for a major aerospace firm. I put together a proposal to save $750,000 worth of energy costs per year (at the then prevailing prices). When I presented my proposal to the V.P., he said it was all well and good, but as a defense contractor "we" worked on a cost plus contract. Turns out my job was only present to comply with government contract requirements, not to actually implement any real conservation.
