Small hydropower projects (SHP) are emerging as solution for sustainable, eco-friendly, long term and costeffective water or renewable energy resource for future. Selecting the appropriate small hydropower project site and its parameters in which to invest is a critical task involving different factors as each project is unique and site specific. Hence such decision-making can be viewed as a mu...

U.S. regions are expected to follow the national trend towards investment in renewable energy as part of their electricity portfolio. The progress of energy portfolios that typically involves traditional methods, such as centralized nuclear and coal-fired generation, and towards cleanerand renewable-source generation will impact economic growth and public health. Renewable electricity productio...

geothermal investors need to be confident with the methods and results of exploration programs. also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...

Due to low energy price, economic optimization of consumption has no justification for users in Iran. Nowadays, the issue of ending fossil fuels, production of greenhouse gases and the main role of building in consumption of considerable amount of energy has drawn the focus of global researches to a new concept called net zero energy building. In this study, modeling, simulation and energy anal...

Synthetic ammonia, manufactured by the Haber–Bosch process and its variants, is key to securing global food security. Hydrogen most important feedstock for all synthetic ammonia processes. Renewable production relies on hydrogen generated water electrolysis using electricity from hydropower. This was used commercially as early 1921. In present work, we discuss how renewable subsequently emerged...

Energy generated by the force of water in hydropower can provide a more sustainable, non-polluting alternative to fossil fuels, along with other renewable sources of energy, such as wind, solar and tidal power, bio energy and geothermal energy. Small scale hydroelectricity in Iran is well suited for “off-grid” rural electricity applications, while other renewable energy sources, such as wind, s...

the biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. efficient utilization of existing infrastructures has a prominent role in response to the challenges. energy hub approach embraces performance of different energy networks. energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...

Currently, hydropower accounts for close to 16% of the world’s total power supply and is the world’s most dominant (86%) source of renewable electrical energy. The key resource for hydropower generation is runoff, which is dependent on precipitation. The future global climate is uncertain and thus poses some risk for the hydropower generation sector. The crucial question and challenge then is w...
