most solar is cheap unless you have to
a. heat your house or water
b. run AC
c. use electric ovens, stoves, space heaters
since camping was brought up, we do have camp stoves/lanterns
for outdoor use with 4 cans of “white gas” as well.
for indoors, the butane stoves work really well.
but what we used last time
was our old Weber charcoal grill.
it has been a real workhorse.
