“…Öko-Institut and Prognos [91] estimate the grid expansion demand to be almost the same in the scenario with higher and lower PV shares. Gils et al [86] and Kendziorski et al [87] find the grid expansion needs to be lower in their scenarios with high PV capacities than in their scenarios with lower PV capacities. Comparatively low-grid expansion requirements can be explained by the fact that with increasing PV generation occurring close to loads, less electricity may need to be transported across longer distances.…”

“…To obtain a large data set, we consider both journal papers and gray literature studies written in English and German. To our knowledge, there are in total 10 studies that fulfill these criteria and which we therefore refer to in our analysis [84][85][86][87][88][89][90][91][92][93]. It may be noted that in addition to the considered long-term studies, there are also similar studies that look at the rather medium future of the German electricity system [94-98].…”

“…Reiner Lemoine Institut [92] models that in their offshore scenario, less PV is added in the southern regions, while the capacities of all other technologies are nearly equal in their distribution across regions compared to the alternative scenarios. Kendziorski et al [87] also model for their scenario with high offshore shares that less PV plants are added in the South, and that less onshore wind turbines are added in the South compared to the alternative scenario with lower offshore capacities. This is because these capacities can be substituted by an increased offshore wind generation.…”

Background Renewable energies are key to reduce CO2 emissions and other environmental impacts of fossil-fueled electricity generation. However, renewable energy systems can also cause negative environmental effects. In this paper, we analyze the potential environmental trade-offs associated with different spatio-technical (de)centralization options for a renewable electricity system. For this purpose, we first review the potential environmental life cycle impacts of key technologies for renewable electricity systems. Subsequently, we develop a framework identifying which factors determine actual environmental effects of renewable electricity systems. We apply the framework to four basic spatio-technical (de)centralization options for the future Germany electricity system. Results Our analysis shows that all (de)centralization options are associated with potential environmental trade-offs. We find that the (de)centralization of the system is a relevant factor determining these trade-offs. For instance, the two more centralized options considered have lower environmental impacts related to PV, whereas the two more decentralized options have lower environmental impacts related to grid infrastructure. However, we also find that the trade-offs depend on the specific way (de)centralization is pursued. For instance, only in one of the two considered more decentralized development options, there is a potential environmental trade-off between higher impacts related to battery storage and lower impacts related to offshore wind power. Conclusions Our analysis reveals that the spatio-technical (de)centralization of a renewable electricity system plays a role for its environmental trade-offs while further factors like the institutional and stakeholder management in place also shape the environmental trade-offs. Policy makers should acknowledge the identified potential environmental trade-offs and their influencing factors when making policies favoring certain spatio-technical (de)centralization options.

The single main resource for the survival of humankind on this planet is the sunlight and it is freely coming to every home like the life-supporting gas, oxygen, is coming to every individual. When society becomes master in harvesting such a precious, Omnipresent, carbon-neutral, clean, freely and abundantly available renewable energy resource sunlight in a suitable form of chemical energy such as, H2, O2, CO, methanol, gasoline (petrol), diesel, etc., with a minimum conversion efficiency of 10% by using carbon dioxide (CO2) and water (H2O) as energy storing materials, which is referred to as the “Practicable Artificial Photosynthesis (PAP)” process, it can be employed for commercial practice with economic viability to meet all the energy needs of the society without any back-up by electricity generated at thermal power plants by burning greenhouse gas CO2 releasing fossil fuels. In fact, the PAP process is the only option available today for humankind to make energy, environment, economy, and life sustainable on our only habitable planet, Earth. In this article, (i) how the PAP process can change the global energy economy and energy dynamics of the world while solving all the humanities top 10 problems for the next 50 years, (ii) how the entire CO2 gas generated as a waste across the globe at all the major outlets can be eventually converted into petrol (i.e., gasoline) given the fossil fuels cannot sustain our civilization’s economic growth, (iii) the effectiveness of existing CO2 sequestration vs. carbon capture and utilization (CCU) processes, (iv) nature’s response to anthropogenic CO2 gas rise in the atmosphere, (v) steps involved in the realization of a desirable PAP process, (vi) why silicon photovoltaic cell (SPVC) solar panels cannot solve the energy problems of our society considering the outcome of Germany’s Energiewende program, etc., have been meticulously presented and described in this article.

A Simple Conceptual Model of Energy Transition

A conceptual model of the electricity market is formulated. Demand can be either high or low, with given probabilities. Inflexible production units with high fixed cost supply the base load of low demand, while flexible units with lower fixed cost and rising marginal cost supply the rest. In a reference case, all production units cover exactly their fixed cost from inframarginal rents. Then a transition to renewable energy is analyzed. There is a certain probability that the renewable energy will not be available, but when it is, it supplies the previous base load. A back-up capacity to supply peak demand is assumed to be made available. The effect of availability of renewable energy on electricity price and fixed cost recovery is analyzed.
