Unless you're arguing that people should kill themselves to save their 100W of power, the future energy use of every alive human is already committed and doesn't matter.
Not to mention that the energy should also include all the extra energy spent on making converting energy into a form that is usable by humans (ie. food). There is probably at least an order of magnitude.
