Electric energy is responsible for several factors that keep us active and in communication with the rest of the world, where they present various ways of producing electric energy, including renewable energies. The most used type of energy is linked to non-renewable sources, causing numerous environmental impacts, other types can be described for power generation considering less consumption, greater stability, lower cost as in the case of piezoelectricity, which is still little used. However, it proves to be a highly efficient alternative, given the generation of energy by means of piezoelectric crystals, mechanically stimulated by pressure (scalar magnitude of mechanical condition, presented in physics), which proves to be an advantage given the types of production power.

Abstract The use of biomass for renewable energy production is one alternative to reduce the environmental impacts of energy production worldwide. Sugarcane-based ethanol is one of the most widespread biofuels in the road transport sector and its development has been encouraged by strong incentives on production and use in several countries. The growing realization on the environmental impacts of ethanol production indicates the need to increase the efficient utilization of biomass resources by optimizing the production chain sustainably. This paper evaluates enhancements in the ethanol production chain quantitatively by identifying opportunities for agricultural intensification and investments in advanced biorefineries in a least-cost optimization model. Results of our model show that significant cost and environmental benefits can be achieved by modernizing sugarcane agriculture in Bolivia. Demands for ethanol and sugar can be met cost-effectively by increasing sugarcane yields from the current country-average of 55.34 ton/ha to 85.7 ton/ha in 2030 with a moderate cropland expansion of 11.4 thousand hectares in the period 2019-2030. Our results further suggest that it is cost-optimal to invest in efficient cogeneration in biorefineries to maximize the renewable energy output and the economic benefits of sugarcane ethanol. Finally, biofuel support in the range of 8-10 US$/GJ is required for investments in second-generation ethanol in biorefineries to be cost-competitive in the medium-term..

Industrialization Process

Energy consumption inconspicuously bridges nature and culture. Modern societies and cultures depend on intensive energy use from the extraction of natural resources. In fact, the industrialization process required large amounts of energy, but main sources such as oil and coal, have been gradually depleted and found to be heavily polluting the environment. Despite their environmental impacts, these resources have provided cheap and abundant power to fuel technological progress and economic growth. (See Agustoni and Maretti [2012] for a good historical summary of the relations between energy production and usages.)
