Abstract With the day by exhausting nonrenewable resources, it becomes crucial to focus on renewable sources of energy and get maximum output from them. Wind is a major source in many parts India. Other such are solar energy, biomass etc. Our objective during this project was predict wind speed for medium-term so as help farms channelizing an efficient manner throughput farms.
Cities are increasingly challenged in sustaining their growing populations with food. As fossil energy reserves are depleted, the sustainability of food production is highly dependent on the ability to yield more food relative to resource use. In preparing cities for peak oil, urban food systems are therefore needed that make better use of local and renewable resources, as opposed to imported a...
Using a significant quantity of fossil fuels has adverse impacts on our lives and will affect future generations. Additionally, there are limited and decreasing numbers of nonrenewable resources around the world. In contrast, renewable resources are not depleted and provide energy with negligible pollution. Wind energy is one of the more common renewable energy resources. This project aims to e...
China's economic growth is expected to continue into the next decades, accompanied by sustained urbanization and industrialization. The associated increase in demand for land, water resources, and rich foods will deepen the challenge of sustainably feeding the population and balancing agricultural and environmental policies. We combine a hydrologic model with an economic model to project China'...
Sustainable energy utilization and environmental protection are important to sustainable economic growth. In this paper, we develop an endogenous economic growth model and discuss the optimal path of sustainable economic growth with the constraints of energy and environment. We find that sustainable economic growth can be achieved only when the relative contribution rate of environment protecti...
Standard endogenous growth models rely on the arbitrary assumption that the technology has exactly constant returns with respect to producible inputs. Can this knifeedge restriction be relaxed by including non-renewable resources as necessary inputs in production? In a one-sector optimal growth model, we find that the strain on the economy imposed by the need to extract successively smaller amo...
The increasing awareness that there are limits to the availability of nonrenewable resources, as well as that there are limits to the biosphere’s ability to absorb wastes, are at the basis of the growing interest about Microbial Fuel Cells (MFCs) technology, with particular regards to their application to wastes treatment. MFCs, in fact, couple the direct electric power production to the degrad...
This review outlines the current and emerging applications of biotechnology, particularly in the production and processing of chemicals, for sustainable development. Biotechnology is "the application of scientific and engineering principles to the processing of materials by biological agents". Some of the defining technologies of modern biotechnology include genetic engineering; culture of reco...
