This paper explores the role of electricity in the transition to renewable energy to mitigate climate change. A systematic literature review with the Scopus database identified 92 papers relevant to the renewable electricity transition. A PESTLE (Political, Economic, Sociological, Technological, Legal, and Environmental) review of the papers provided a multidisciplinary analysis. The Paris Agreement created a global movement for carbon neutrality to address the threats of climate change, calling for a transition to renewable electricity to lead the way and expand into new sectors and regions. Although smaller renewable technologies are ramping up, complexities thwarting the transition include locked-in assets, high upfront costs, variability of solar and wind energy, infrastructure, difficulty in decarbonizing transportation and industry, material resource constraints, and fossil fuel support. This research found that renewables are not replacing fossil fuels to date but adding further energy demands, so that greenhouse gas emissions rose in 2021 despite an increased renewable electricity share. Without a major shift in the trillions of dollars of subsidies and investment away from fossil fuels to renewables, catastrophic climate change is predicted. This paper found that the Paris Agreement’s commitment to net-zero carbon and the transition to renewable electricity are undermined by record-high levels of subsidies and financing for fossil fuel industry expansion. Transitioning to a climate-neutral economy requires an investment away from fossil fuels into renewable energy ecosystems. Renewable electricity provides possibilities to realize sustainable development goals, climate stabilization, job creation, a green economy, and energy security with careful planning.

“…An innovating solution would be considered as usage of recycling energy resources, as being most viable, cheap, ecologic, and avoidable for any state, poor in natural resource s. The increase of the consumption of recycling energy by producing electrical energy and heat is at the basis of an ecological energetic transaction [7]. For the countries that are rich in biodegradable litter the designing of the biogas installation would be first option.…”

The latest excessive industrial development has led to both the increase of the fossil fuel consumption and an excessive pollution. A saving solution would be considered renewable energy sources, best based on wastes, which prove energy content. The current work focuses on a case study for the biogas production, using anaerobic digestion of poultry dejections, by means of a latest generation bio-processor. These dejections are presently and normally used only as fertilizer. The experiment was performed simultaneously in 6 digesters, which were loaded daily with a quantity of material resulting from the calculated recipe, based on the characteristics of the poultry litter. Preliminary experimental analysis such as calorific value, humidity and volatile content were run. Following the results obtained, one can state that the poultry litter can be used as raw material for the anaerobic biogas production, in the future, as well.

“…Some studies deal with variation analysis of the combination of electricity and green gas, which offers several advantages in terms of efficiency and resources [42]. An example of a comprehensive assessment for various scenarios of the future development of a decentralized system of renewable energy sources is given in [43], which identified the main environmental disadvantages: an increase in the use of mineral resources and emissions of pollutants due to the necessary technical infrastructure and a significant increase in the use of resources for burning biomass.…”

Mineral Policy within the Framework of Limited Critical Resources and a Green Energy Transition

et al. 2021

The green energy transition is associated with the use of a wide range of metals and minerals that are exhaustible. Most of these minerals are limited in access due to small resource fields, their concentration in several locations and a broader scale of industry usage which is not limited exclusively to energy and environmental sectors. This article classifies 17 minerals that are critical in the green energy transition concerning the 10 main technologies. The following classification signs of metal resources were used: (1) the absolute amount of metals used in the current period for energy;(2) projected annual demand in 2050 from energy technologies as a percentage of the current rate;(3) the number of technologies where there is a need for an individual metal;(4) cumulative emissions of CO₂, which are associated with metal production;(5) period of reserves availability;(6) the number of countries that produced more than 1% of global production;(7) countries with the maximum annual metal productivity. The ranking of metals according to these characteristics was carried out using two scenarios, and the index of the availability of each mineral was determined. The lowest availability index values (up to 0.15) were calculated for cobalt, graphite and lithium, which are key battery minerals for energy storage. Low indices (up to 0.20) were also obtained for iron, nickel and chromium. The calculation of the availability index for each mineral was enhanced with linear trend modelling and the fuzzy logic technique. There are two scenarios of demand–supply commodity systems with a pre-developed forecast up to 2050: basic independent parameter probability and balanced fuzzy sum. Both scenarios showed comparable results, but the second one highlighted supply chain importance. Generally, the lowest availability index values (up to 0.15) were calculated for cobalt, graphite and lithium, which are key battery minerals for energy storage. Low indices (up to 0.20) were also obtained for iron, nickel and chromium. The fuzzy logic model helped to reveal two scenarios up to 2050. The two scenarios presented in the current research expose a high level of uncertainty of the projected 2050 forecast.
