• I am going to assume that you are not American, so you are ignorant about how our laws work. The DOE is enforcing parts of the Energy Policy and Conservation Act that were amended by the Energy Independence and Security Act of 2007, which I mentioned in my previous reply.

      You can read the bill here: https://www.congress.gov/bill/110th-congress/house-bill/6/text . Including this:

      Amends EPCA to prescribe energy efficiency standards for general service incandescent lamps, rough service lamps, and other designated lamps.

      So yes, the DOE is making rules but it can’t makes rules in a vacuum. It is directed to do so by the bills signed into law by the President of the United States (or in some cases just by Congress if a veto is overridden). In 2019, the Trump administration’s DOE blocked the rule that was going to be implemented. In 2023 the Biden administration’s DOE enforced the rule. None of this could happen without congress.
