This research investigates the co-movement and causality relationships between greenhouse gas emissions, energy consumption and economic growth for 16 Asian countries over the period 1990-2012. The empirical findings suggest that in the long run, bidirectional Granger causality between energy consumption, GDP and greenhouse gas emissions and between GDP, greenhouse gas emissions and energy cons...
Food is a major contributor of greenhouse gases in the world. Changing what you eat to a less greenhouse gas intensive diet can have a major impact on the greenhouse gas emission. While campaigns and efforts about changing diets directed towards individuals have a potential to reduce total greenhouse gases, efforts directed towards institutional producers of meals have much greater potential to...
Economic freedom is known to have a profound effect on the efficient allocation of resources. Without subsidies, tariffs, and other government interventions, economic activity operates in the most efficient manner because of competitive pressures to produce more with fewer inputs. This means that energy use per unit of production is decreased with the presence of free markets (Graph 2). Free ma...
Volume 2 • Issue 1 • 1000e104 Adv Dairy Res ISSN: 2329-888X ADR, an open access journal Although water vapour is the largest and essential greenhouse gas inclusive of ozone in the stratosphere, the mitigation of anthropogenic six greenhouse gases such as carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons and perfluorocarbons have been established as legally binding...
Global warming is likely one of the most serious and urgent issues facing the U.S. transportation sector. Major reductions in greenhouse gas emissions from the transportation sector will be needed in order to stabilize the climate and avoid the most serious effects of global warming. Travel models can play an important role in evaluating potential policies for reducing transportation sector gre...
Stomata of growth chamber-grown Vicia faba leaves have an enhanced CO(2) response, measured as change in stomatal aperture, compared to stomata of greenhouse-grown leaves. Reciprocal transfer experiments showed that the stomatal response to CO(2) acclimated to the growing environment. Stomata of growth chamber-grown leaves transferred to a greenhouse lost their high CO(2) sensitivity within 2-3...
Feed and food production are inter alia reasons for high greenhouse gas emissions. Greenhouse gas emissions could be reduced by the replacement of animal components with plant components in processed food products, such as pasta. The main components currently used for pasta are semolina, and water, as well as additional egg. The hypothesis of this paper is that the substitution of whole egg wit...
Host suitability of commercial sunflower hybrids to Pratylenchus zeae was studied in the field and greenhouse. For comparison, one maize and one grain sorghum inbred line, both susceptible to P. zeae, were included in the greenhouse experiments. Pratylenchus zeae densities extracted from the roots of sunflower hybrids grown in naturally infested soil were low. In the first greenhouse experiment...
Since the 1970s, installed solar photovoltaic capacity has grown tremendously to 230 gigawatt worldwide in 2015, with a growth rate between 1975 and 2015 of 45%. This rapid growth has led to concerns regarding the energy consumption and greenhouse gas emissions of photovoltaics production. We present a review of 40 years of photovoltaics development, analysing the development of energy demand a...
This communication deals with the development of a mathematical model for experimental validation of the thermal behavior in the greenhouse after evaporative cooling. Extensive experiments have been performed during July to October 2000 for an even span greenhouse of effective floor area of 24 m and having a brick north wall. A parametric study involves the area of the cooling pad (height of co...
