“…This amount is based on a global bio energy assessment survey [10]. The expansion of renewable energies defined in ADV are based on recent technology trends [11]*, regional renewable energy potentials, current and future deployment costs [12], [13], and market development projections of the renewable energy industry [14], [15], [16], [24], [17], [18]. In ADV, the annual markets for the dominant renewable power generation technologies will maintain the annual growth rates of the past decade (2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015) until 2030 to sustain the expansion rates of the renewable energy RE industry, and will decline to one-digit values between 2030 and 2050 (Table 17, appendix).…”

To meet the terms of the 2015 Paris Agreement, the global energy system must be entirely decarbonized by the end of this century. Two scenarios have been developed: a reference case (REF) and an advanced 100% renewable energy scenario (ADV). ADV reflects the trends in global energy systems and will decarbonize the entire energy system by 2050. Those results are compared with the IPCC AR5 450 ppm scenarios, in terms of the 2050 energy demand projections-primary and final energy-and the demands for the transport and building sectors because they are important in urban environments. The results are further discussed with regard to the impact on urban infrastructures and the role of megacities in the global energy consumption pattern. Under the assumption that urbanization rates will remain at the 2015 level until 2050, the annual energy demand for buildings in urban areas is expected to increase by 27 EJ under the reference scenario (REF), from 57 EJ to 84 EJ per year, whereas ADV would lead to an overall reduction to 46 EJ per year by 2050, while the population and GDP continue to grow. Overall, the global energy demand in the transport sector is expected to increase by over 60% by 2050 under REF, whereas the deep mitigation pathway (ADV) reduces the transport energy demand below that of the base year, to 70 EJ per year. This is a significant reduction, even compared with other 450 ppm scenarios, and can be achieved by a drastic shift to electric mobility in response to vehicle efficiency standards, a phasing-out of combustion engines in the transport sector by 2030, and a modal shift in favor of urban public transport. The global energy demand for the building sector in ADV shows a smaller deviation in comparison to other 450 ppm scenarios than that for the transport sector.

“…PV technologies harvest global horizontal irradiance (GHI). Because many global or regional PV technical potential estimates do not apply GHI thresholds [23][24][25][26], and because GHI values in India exceeded most thresholds previously used (e.g., 1500 kWh/m 2 and 1400 kWh/m 2 [27,28]), we did not apply any GHI resource threshold for PV. For each remaining ith suitable cell, we then estimated the available annual GWh generation using: PD*CF i *8760/1000, where PD is power density or the MW produced per km 2 (2 MW/km 2 for wind, and 26 MW/km 2 for PV), CF i is the spatially explicit capacity factor based on Wu et al [29] as estimated in Baruch-Mordo et al [22], 8760 are the number of hours per year, and 1000 is a conversion factor from Sustainability 2020, 12, 281 5 of 14 MW to GW.…”

India has committed to reduce emissions with a goal to increase renewable energy production to 175 gigawatts (GW) by 2022. Achieving this objective will involve rapidly increasing the deployment of solar and wind energy, while at the same time addressing the related challenges of the financing requirements, environment impacts, and power grid integration. Developing energy on lands degraded by human activities rather than placing new infrastructure within natural habitats or areas of high production agriculture would reduce cumulative impacts and minimize land use conflicts. We estimated that converted lands have the potential capacity of 1789 GW across India, which is >10 times the 2022 goals. At the same time, the total land footprint needed to meet India’s 2022 renewable energy target is large, ranging from ~55,000 to 125,000 km2, which is roughly the size of Himachal Pradesh or Chhattisgarh, respectively. If renewable energy is advanced with the singular aim of maximizing resource potential, approximately 6700–11,900 km2 of forest land and 24,100–55,700 km2 of agricultural land could be impacted. Subsidies and incentive programs aimed at promoting low-impact renewable energy deployment and establishing mitigation obligations that raise costs for projects that create land-impacts could improve the public support for renewable energy.

“…In fact, studies about ultimate potentials of renewable energy sources reveal that solar conversion is the only source able to fulfill future demand for energy by itself, unlike e.g. wind [2]. However, PV has the inherent drawback that its supply is subject to the cycles of nature (dayenight, summerewinter).…”
