The purpose of this paper is to investigate the social acceptance of renewable and non-renewable energies in Iran using the social acceptance pyramid.

Today, social acceptance is considered a very important phenomenon in the development, implementation and achievement of energy policy goals. Low acceptance will make it difficult to achieve energy development goals; therefore, social acceptance must be taken into account when making policy. Firstly, the model criteria, using data obtained from questionnaires, are weighted by the Shannon entropy method and, finally, four sources of fossil, nuclear, wind and solar energy were ranked by means of VIKOR, Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

The results show that, in Iran, the social acceptance criterion and trust sub-criterion are the most important criteria for energy acceptance. The results of the ranking of options based on multiple-criteria decision-making (MCDM) techniques show that, given Iran's specific energy requirements, social acceptance of fossil energy is higher than wind, solar and nuclear, and wind, solar and nuclear energy come later in the rankings.

This research contributes to the literature in two ways: Firstly, social acceptance is considered a very important phenomenon in the development, implementation and achievement of energy policy goals; thus social acceptance must be taken into account when making policy. The results of the ranking of options based on MCDM techniques show that, given Iran's specific energy requirements, social acceptance of fossil energy is higher than wind, solar and nuclear, and wind, solar and nuclear energy come later in the rankings. Also, the social acceptance criterion and trust sub-criterion are the most important criteria for energy acceptance in Iran.

This study first aims to survey the state of user innovation in Iran and then identified barriers and incentives for user innovation in Iran.

In this study, a questionnaire (through 1,360 adults from Iran) prepared by De Jong (2016) was used to survey user innovation.

The results showed: the percentage of user innovators is high in Iran, there is no linear relationship between the income of a country and the percentage of the user innovators, there is a positive relationship between the education level and the percentage of user innovators in Iran, there is no linear relationship between the number of people educated in the scientific and technical fields and the percentage of user innovators. Finally, based on surveying users opinion in questionnaire, four incentives and five barriers in user innovation were identified that can help policymakers to improve their innovation policies.

Literature review in this field showed it was found that in a number of developed countries, the issue of user innovation has been addressed, but in Iran as a developing country, no such research has been conducted so far. In addition, it was found that so far, no comprehensive research has identified barriers and incentives for user innovation, so this study, first surveyed the state of user innovation in Iran and then identified barriers and incentives for user innovation in Iran.
