As controlling carbon emissions is critical in dealing with climate change, renewable energy is an appropriate way to satisfy energy demand without degrading the ecosystem ( Jing, 2016). To satisfy the ever-increasing energy demand and to protect the climate, breakthrough advancements have been made in the past to design technologies that can control and harness power from alternative energy sources. Currently, the majority of the world's energy consumption is satisfied by consuming energy created using fossil fuels. According to International Energy Outlook (2013), global energy demand will be increased by 56 per cent between 20 ( Azad et al., 2014). Globally, the population is growing at fast rate however, the world's energy demand is likely to grow even more rapidly than the increase in the population. There is a three-dimensional relationship alongside a bi-directional causal relationship between economy, the environment and energy ( Azad et al., 2014). For economic growth and human advancement, energy has always been universally considered one of the most crucial measures ( Rawat and Sauni, 2015). A renewable energy supply offers a solution to both challenges. These so-called fossil fuels, when burned, release heat energy which is then converted into electricity releasing into the atmosphere a lot of carbon dioxide (CO2), a greenhouse gas that contributes to the issue of global warming. The majority of the world's power is generated from the use of coal, oil and gas. Currently, this demand is being met through the increased use of fossil fuels. Matching supply with this surging demand is a principal and critical challenge for countries around the world. The world's population is growing at an unprecedented rate and that has necessitated a dramatic increase in energy demand globally. With less polluting and lower tariff energy solutions being made available to local people, and higher profits for manufacturers, this will create an atmosphere where all stakeholders are satisfied. By breaking research and development-related barriers, organizations will be able to invest greatly in developing advanced technologies that can optimize usage of renewable energy and make renewable energy appear more lucrative. This research shows that social, technological and regulatory barriers have a strong influence on the deployment of renewable energy, while economic barriers significantly influence it indirectly. Data were collected through an online questionnaire responded to by 223 professionals working in the energy sector all over the globe. The objective of this research is to find out the impacts of social, economic, technological and regulatory barriers in the deployment of renewable energy. Several economic, institutional, technical and socio-cultural barriers hinder countries from moving from the high to the low emission pathway.
