The word sustainable has sometimes replaced renewable and
non-renewable, but all three are loosely defined. If we draw the line
at 2000 years at present consuption; then only oil, helium, and
methane = CH4 = natural gas are likely to be in very short supply, but
a dozen items will be priced beyond some of their present uses. If we
figure two billion years, we will possibly run low on rocks, sand, top
soil, trees, oxygen plus most of the other items currently used for
construction ect. In the 20th century we have seen mercury and tin out
price several of their former uses. In both cases there were other
reasons for the steep price rise besides the numerious mines that were
mined out.
 Since most plastics are made from oil or methane; the plastic used in
construction will likely become impractical for most applications in
100 years extrapulation of recent plastic making.
 Do you intend to limit "construction" to private homes and commercial
buildings, or do you have much broader meaning, including roads,
bridges, aircraft, space ships, computers and toys?   Neil

Perhaps you are thinking energy? Hundreds of ideas have been tried
which have advantages. Do you wish to ignore disadvantages that all
these ideas have? ie we can construct the south wall of buildings of
glass or other transparent material, in the southern 3/4th of the
North temperate zone.  Initial cost and long term cleaning costs are
higher than for most more convential materials. As much as 10% of the
volume of the building is too hot in summer for most uses, even with
wider (and coslier) than usual eves to block the noon day sun in
spring and summer. The transparent surface puts an extra beam of
sunlight (it behaves like a mirror) into neigboring property, which
could cause these owners to seek compensation.   Neil
