Energy is conserved because we want our theories to be time translation invariant (c.f.
Noether's theorem).

Hi Roger,
I would say the opposite - energy not being conserved would pose a harder challenge to
materialism, because then you'd have to ask where it comes from and where it goes.

Does energy obey the laws of materialism ?
Energy presents us with an argument against materialism,
(or at least materialism as I understand it) since is conserved,
regardess of form or physical location. Thus the electrical energy created
in a generating station at one location can be transported down
a copper wire to a house miles away. It will seem to lose some
value due to the heating by resistance in the wire, but
that is merely a conversion of electrical to heat energy and
the total is maintained. But all of this occurs over a range
of locations, not in a single body of material.
Similarly in a pendulum clock, there is a continual conversion of
energy from potential energy to kinetic energy and back
again, but some nonphysical marker outside of spacetime keeps the
total constant.
Etc.
I would say that the nonphysical marker outside of the physical
world is mental energy, or the idea of energy, and it is this (a
nonphysical idea rather than a physical quantity) that is actually
maintained. Leibniz in his Idealism gives a similar account to the
transfer of "momentum" between colliding bodies, maintaining,
quite reasonably, that momentum is an idea rather than a thing.
In other words, there is no such physical thing as momentum, only
the idea of momentum.

Are you saying that energy is non physical?

Either way it is still non physical - it is energy and remains
