The use of renewable energy has been very important in recent decades for conserving nature, conserving its natural resources, and reducing environmental impacts. According to the ONU in 2019, greenhouse gases increased from 123% to 147% in the atmosphere, so one of the best alternatives that will help preserve our nature is geothermal energy, helping not only to take care of the environment but also to generate electricity, since in several countries the main problem is the lack of electricity, because it is essential for our daily tasks. This article presents it as a natural resource of our ecosystem that must be used to the maximum for electricity generation. For this, we will announce the most suitable places, for an optimal design. It will show different places in Peru that have the features, where you can implement a geothermal system. Tacna is the most relevant place with a lot of geothermal energy, and this was the place chosen for the geothermal system. It is therefore essential to exploit energy that is not exhausted, thereby increasing the use of new clean energy sources.

“…With the increase in in-depth research on multi-stage centrifugal pumps worldwide, performance optimization has always been a research hotspot. Improving the optimized design and performance of multi-stage pumps can not only contribute to the advancement of energy systems in China, but will also provide a reliable research basis for developing the global renewable energy market [3][4][5].…”

In order to improve the hydraulic efficiency and internal flow pattern of a multi-stage pump under multiple flow conditions, an intelligent optimization design was proposed for its hydraulic components. Sensitivity analysis was used to select the key parameters influencing the hydraulic efficiency of a multi-stage pump. The optimal Latin hypercube sampling and non-dominated sorting genetic algorithm Ⅱ were employed to build a multi-objective optimization system. Moreover, a radial basis function neural network was adopted as the surrogate model of hydraulic efficiency. The research results showed that the impeller outlet width, impeller blade wrap angle, impeller outlet blade angle, and diffuser inlet width were the key factors affecting the hydraulic efficiency. The efficiency of the optimized model increased by 4.35% under the design condition and the matching of the internal flow between the optimized impeller and diffuser was significantly enhanced under the nominal condition. The improved flow pattern could be clearly observed in the flow passage of both the pump impeller and the diffuser. After optimization, the wear performance of the model was also improved compared to the original design. The wear area decreased in size and was distributed more evenly, resulting in a noticeable decrease in the maximum amount of wear.

“…The International Energy Agency (IEA) forecasted a global geothermal production of 140-160 GW in 2050, with a 60% share provided by EGS (IEA 2011). Such systems have been studied with eld experiments throughout the world in different geological environments (Palacio-Villa et al 2020), for example, the Fenton Hill project in the United States (Reiter et al 1976), Soultz-sous-Forêts in France (Cuenot et al 2008), Basel in Switzerland (Wyss and Rybach 2010), Groß Schönebeck in Germany (Huenges et al 2006), Paralana in Australia (King et al 2009), Ogachi in Japan (Kaieda 2012).…”

Advances in new technologies and the desire to achieve a sustainable and safe energy supply, enable communities to transition from conventional to renewable resources, such as geothermal energy. Perception and acceptance amongst different audiences have a high impact on the feasibility of energy projects, which is an important aspect to analyze. For this reason, this study focuses on describing the level of awareness and acceptance of deep geothermal energy within an educated segment of the population in five European and American countries (Canada, Colombia, Chile, Belgium, and France) at different stages of geothermal development. This study was conducted through an online survey, which was targeted to post-secondary students and professionals. Some of the most significant conclusions are: 1) there is a high degree of awareness of geothermal energy among the respondents in Chile and Canada, a medium level in Belgium and France, and a low one in Colombia; 2) there is a favorable acceptance of a geothermal project in each country, even when hydraulic stimulation is considered; 3) environmental aspects and community safety are the most important issues that must be addressed to support a pilot geothermal project.
