The importance of solar energy is increasing due to climate change and similar reasons. However, the biggest barriers investments are high initial investment cost long payback period. In this study, effects technological developments in period examined. It has been investigated how increase PV panel efficiency affects systems. annual average profit, daily gain be obtained according different va...

In this paper, a novel integrated system is proposed to improve the performance of a conventional low-grade geothermal-based organic Rankine cycle (ORC). The main idea is to utilize two TEG units to recover the waste heat of the condenser and geothermal brine. The proposed model is investigated and compared with simple ORC from the energy, exergy, and exergoeconomic viewpoints through the param...

Many consumers are transitioning away from single-use plastic products and turning to reusable alternatives. Oftentimes, this change is being made with the assumption that these alternatives have fewer environmental impacts; however, frequently more environmentally intensive materials use phase impacts. This study used LCA examine GWP, water consumption, primary nonrenewable energy associated f...

In general, healthy networks seem to result in improved community welfare i.e., they are characteristic of public benefits. The converse is true of unhealthy networks. This paper explores if healthy networks are where limited government funding should be focused in order to get the greatest social payback, or if these funds should be spent helping to improve the strength of less healthy network...
