Clem’s career took him from in-house safety inspector for one of the largest geothermal plants on Mars, through lead safety coordinator, into middle management, and finally Director of the compliance department. He retired early to take a lobbyist role on behalf of the industry, where his knowledge of the industry and its ability to comply with regulations was a great benefit. He successfully lobbied for a tightening of safety regulations (most geothermal plants were already safe enough to fall within the new guidelines, while their primary competition, microwave power, would have to spend billions to comply, and would thus need to raise their prices) an effort that was led, in the Senate, by Senator Hanson. He spent several months in Luna City working out the details with her, and when it finally passed, it solidified geothermal energy as the primary source for Martian society.
