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 |
