Solar energy has the greatest energy potential among all types of renewable energies. In 2018, the annual demand for electricity worldwide was 22,964 TWh. Daily, earth receives about 174 PW in the form of solar irradiance. This means that, if all this radiation could be harnessed, in approximately 8 minutes the electricity needed to meet the global annual electricity demand could be generated. Therefore, the need arises to implement photovoltaic systems that take better advantage of the solar resource, but in turn provide greater economic profitability. This article aims to evaluate the technical and economic feasibility of photovoltaic systems with solar trackers and compare them with fixed structure systems in “El Valle de Sula”, Honduras, Central America. The research was able to determine the levelized cost of electricity (LCOE) of each type of photovoltaic system from the generation of electricity in municipalities comprising the study area and the costs associated with initial investment, and operation and maintenance of each photovoltaic system. This research was carried out by implementing a methodology with a quantitative approach, using data collection to test hypotheses, based on numerical measurement and statistical analysis. Considering the value of the land, the photovoltaic system with a horizontal axis tracker has the lowest LCOE in 14 of the 18 municipalities of “El Valle de Sula”. Without taking into account the value of the land, the system with the lowest LCOE in all municipalities of this region is the system with a horizontal axis tracker, then the system with a dual-axis tracker and finally the system with fixed structure.
In the department of Cortés, many cities such as San Pedro Sula and Choloma truly invest in auto consumption installations for the residential and commercial sector; however, Puerto Cortés being one of the most prominent cities in Honduras, currently lacks any incentive of interest from its residents or authorities to implement distributive generation of any kind. Under this criterion, it was sought to study a renewable alternative distinct from solar energy suitable for its implementation in Puerto Cortés; Vortex Bladeless being a new concept in wind energy technology. A technical analysis was performed for the Vortex NANO device in situ to develop projections for a Vortex Tacoma device under the same conditions. The electrical performance of the device, the behavior of the wind resource and the power coefficient (Cp) were determined; analysis and results are based of the collected date on the 3rd quarter of the year. A demand analysis (load profile) in the residential sector to determine the range covered with one (1) Vortex Tacoma device given its projections.
According to the Intergovernmental Panel on Climate Change, human influence on climate change is evident . The evidence comes from the unprecedented levels ("in at leas t the last 800,000 years") of GHG concentration in the atmosphere. The se levels in 2011, 391 ppm (parts per million) for CO2, 1,803 ppb (parts per billion) for CH4, and 324 ppb for N2O, exceeded le ve ls recorded before industry by approximately 40%, 1 5 0 %, and 20%. [1] The influence of electricity generation by means of fossil fuels has been increasingly noticeable in terms of the effects the y generate on climate change, so that over the years the ge neration of energy by means of renewable energies has been a gre at alternative. Within the Honduran energy sector, it is projected that in the coming years renewable energy generation will have an 80% share in the energy matrix of the Honduran country and only 20% of fossil energy [2], being biogas an alte rnative that has gained strength in recent years due to t h e e nvironmental impact, through biodigesters using organic wast e capable of generating clean energy. It is important to know ho w te mperature affects pH measurements. Therefore, a comparis on of two types of biodigesters, one subway and one above ground, was carried out in order to determine the most suitable for pH and temperature control. In this document the generation of biogas from pineapple waste is projected in two biodigesters, o ne underground and the other exposed to the open air, in addition , the behavior of the internal temperature of the biodigesters is shown, which presents a difference of +/-3 (°C), based on th e te mperature registered in the biodigest ers, a pH be h avi or is de noted, According to these behaviors previously mentioned, it is shown that the pH be yond its composit io n a l so i nf luences i ts be havior based on the temperature that it is exposed to. Th e biogas generation was simulated in Aspen in order to project th e biogas generation capacity in a larger scale biodigester, whi ch re ached a production of 20% of the gas demand of an atypica l house in the rural sector, which is the sector that is sought to help with the elaboration of the prototype.

AbstractPurpose -This article's aim is to demonstrate the pertinence and success of Michelin's worldwide talent and career management model, the purpose of which is to allow all employees to realise their full potential, or ''become what they are''.Design/methodology/approach -The article is an inside account of principles, career management methods, development programmes and measurement tools by two former international career managers with Michelin -one English, one French -responsible for policy design and application, career development for senior management, and identification and development of tomorrow's leaders worldwide. A comparative table demonstrates the stark differences between a ''become what you are'' and a ''do what you know'' approach.Findings -In a corporate culture based on respect for people, successful development of employee potential requires a three-way partnership between employee, line manager and an independent career manager who is ultimately responsible for appointments. Managers do not own their people and individual development takes precedence over short-term operational needs. The model results in cohesiveness, loyalty and business success.Research implications/limitations -This is a case study of one career management model as related by two seasoned professionals responsible for making it work worldwide.Practical implications -The model can be applied in any national culture and across organisational barriers or ''silos''. It is transferable wholly or partially to other organisations, both private and public.Social implications -The result is an improved working atmosphere where employees are generally content to get on with the job and let someone else, calmly and impartially, plan their futures. This person is known, is independent from line management, and has the authority to act.Originality/value -This is not a new theory, but a view from within of a highly successful career management model that has stood the test of time and can be applied universally.
