Are you aware that the majority (over 50%) of the DOE budget is related to maintaining our nuclear arsenal and processing legacy waste from the Manhattan Project era? Beyond that majority of spending, the next highest allocation is for all the laboratories performing cutting edge research in a plethora of non-partisan scientific fields. Further down the ladder of funding you begin to enter the world of partisan (according to republican contemporaries) spending on things like clean energy which totals to less than 10% of the budget. This is an incredibly non-partisan agency which due to science has recently begun to look at climate change, although it's far from it's top priority as evidenced by funding patterns.
The management of some of the DOE sites is shameful and contractor incompetence is all too often forgiven/encouraged (i.e. Bechtel wasting billions at Hanford). Intelligent leadership rather than ape-like chest thumping is required to fix these issues and shepherd our nuclear arsenal, the various Manhattan Era sites and laboratories. I've worked with this agency, and there are plenty of things I would slash and burn about it. I honestly didn't think there could be more incompetence in the world than I saw in some instances working with the DOE until I stumbled across your posts here.
If Trump appointed a no-nonsense, intelligent manager whom wasn't interested in clean energy I would be fine with it because for that particular agency there are larger issues to address (like leaking nuclear waste). However, the particular bootlicking clown he has nominated is non of the above.
