Abstract: The purpose of this chapter is to present a generalized model for the construction of inventories for the production of electricity through biogas. This general framework can be adjusted to any power plant that uses biogas, since it complies with the main material and energy balances. This chapter describes the main technologies used in biogas power energy production, separating them into five main subsystems that integrate the general life cycle inventory, as well as the inputs and outputs considered in the development of the inventories. The life cycle assessment (LCA) of two types of plants is presented as study cases: (i) the biogas power energy generation with organic waste in landfills as substrate and (ii) the biogas power energy generation using dairy cattle manure as substrate. Both systems, in addition to using different types of substrate, present differences in their substages. It is concluded that the generation of studies of life cycle analysis of technologies facilitates decision makers, producers, and government agencies to develop and identify areas of opportunity from life cycle thinking.

TL;DR: In this paper, environmental impacts of an experimental solar absorption air-conditioning system based on a Life Cycle Assessment were evaluated for the first time in Mexico, and the main contribution of environmental impacts in the solar cooling system was the consumption of energy and raw materials for the construction, whereas for the commercial cooling system, the electricity consumption and the use of refrigerant were the major impacts of the operation stage.

TL;DR: Prenatal and postnatal blood lead concentrations are associated with higher rates of total arrests and/or arrests for offenses involving violence, the first prospective study to demonstrate an association between developmental exposure to lead and adult criminal behavior.
Biomass energy: the scale of the potential resource.
TL;DR: The area with the greatest potential for yielding biomass energy that reduces net warming and avoids competition with food production is land that was previously used for agriculture or pasture but that has been abandoned and not converted to forest or urban areas.
