Methane breaks down into CO2, which is a part of the Carbon Cycle. https://en.wikipedia.org/wiki/Carbon_cycle https://en.wikipedia.org/wiki/Carbon_cycle CH4 -> CO2 -> grass -> cow -> CH4 | \/ steak -> human -> CO2 and so on... > If nuclear plants can generate with costs <1¢/kWh, why don't they? Because they're too expensive to build, because of regulation and lack of economies of scale. Similar to why rockets were expensive, before SpaceX. If we invested more, both in research and in building more of them, in factories, we could build plenty, much more cheaply. The technology for modular reactors obviously exists (e.g. nuclear submarines), it just needs to be commercialized. > If your costs are practically zero, isn't your profit margin essentially 100%? You're mixing up or conflating total cost vs marginal cost. The marginal cost of making computer chips is almost 0, but the upfront investment is huge. Same with reactors and nuclear power. If we make more of them, streamline the construction, simplify regulation, etc. the marginal costs will drop massively (as will upfront costs, but they will still be non-zero).
