The wind and solar energy are omnipresent, freely available, and environmental friendly. The wind energy systems may not be technically viable at all sites because of low wind speeds and being more unpredictable than solar energy. The combined utilization of these renewable energy sources are therefore becoming increasingly attractive and are being widely used as alternative of oil-produced ene...

Elasticity of interfuel substitution between renewable and non-renewable energy is a key to establish effective climate change policy.This is the first study estimating the elasticity of substitution between different fossil fuels and renewable resources. We use twelve manufacturing industry level data for the OECD countries over 1995 to 2009. We find complementally relationship from non-renewa...

Renewable and non-conventional distributed energy resources (DERs), such as, wind, solar PV, micro-turbines, fuel cells, diesel generators etc. are gradually becoming more popular as energy efficient and low-emission energy sources. Demand-side management, along with the integration of distributed energy generation and storage, are considered increasingly essential elements for implementing the...

An elegant feature of emergy synthesis is its capability to integrate the diverse inputs required to operate a system into a single metric that represents the equivalent amount of energy of one type. However, integration also presents problems with 1) precise tracking of emergy flows from source to sink, 2) developing and estimating indices, 3) communicating results to non-emergy specialists, a...

a r t i c l e i n f o Due to the growing concern about climate change and environmental sustainability, hybrid renewable energy system (HRES), which refers to a system that combines several renewable power sources and a conventional power generator to cover the power shortage when the renewable power is insufficient, has gained more and more popularity over the decades. While the HRES is very a...

The objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of CO2 emissions for hazelnut production in Guilan province of Iran. Moreover, the sensitivity analysis was done by marginal physical productivity (MPP) method for energy inputs and energy using linear regression. Initial data were collected from 120 orchar...

nowadays energy is one of the most essential needs of human being and it can be considered as the basic prerequisite of social and economic development.  hence, many of the correlations and legislations of a country are affected by it. since iran has huge source of gas and oil, it has turned to a fossil fuel oriented county. but as oil and gas sources are non-renewable ones and cannot be replac...

There is an ongoing debate among energy experts on how providing a subsidy for one energy source affects the investment in other sources. To explore this issue, we study capacity investments of a utility firm in renewable and conventional sources. Specifically, conventional sources are categorized into two groups as inflexible (e.g., nuclear and coal-fired plants) and flexible (e.g., natural ga...

of a dissertation at the University of Miami. Dissertation supervised by Professor Nurcin Celik. No. of pages in text. (95) Environmental issues and reliance on fossil fuel sources, including coal, oil, and natural gas, are the two most common energy issues that are currently faced by the United States (U.S.). Incorporation of renewable energy sources, a non-economical option in electricity gen...
