Limitations Of Underground Building As An Energy Alternative, A. M. Hanna, N. Evans
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Building underground offers a potential for a reduction in heating and cooling loads, in comparison to a similar above ground structure. The resulting energy savings over the life of the structure will be beneficial, both in terms of dollars, and in conservation of resources. However, this mode of construction is subject to technical and economic limitations. The limitations, as well as the potential energy saving processes of underground construction, are discussed with special emphasis placed on the soil properties, structural design and construction techniques... which may unfavourably affect the potential energy savings.

Surface Heating Greenhouses With Waste Heat, P. N. Walker, H. J. Rand
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Surface heating of greenhouses is done by applying waste heated water on the outside of the greenhouse at the ridge and allowing this water to flow in a thin layer over the roof and sidewall surfaces. The water is then collected in gutters and returned to its source. The main advantages of this heating system over others for heating greenhouses with waste heat are its low capital costs and the fact that it can utilize wastes at quite low temperatures. This system can make effective use of water at temperatures as low or perhaps lower than the temperature to be …

Economics, Politics And The Future Supply Of Energy Sources, Raphael Shen
Economics, Politics And The Future Supply Of Energy Sources, Raphael Shen
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
High degree forward linkages created by oil and natural gas consumption was sufficient "justification" to regulate energy prices. The "welfare triangle" was artificially enlarged, and the economy as a whole indeed reaped benefits therefrom. It was workable, then. But the economy has since been experiencing macroeconomic dislocations. To avoid future payments of current policy mistakes, to ensure continued and steady economic growth, and to assure future energy adequacy/ abundance, enhanced investment incentives are rational imperatives that merit serious consideration.
