Economic, environmental, and social assessment of the replacement of coal-fired thermoelectric plants for solar and wind energy in Chile

Economic feasibility of onshore wind energy potential for electricity generation in Zambia

“…According to Satymov et al [29], the results of this study show that there exists a certain hub height that enables wind turbines to deliver the lowest cost of electricity generated, and exceeding that height does not pay off the rise in capital expenditures needed for stronger foundations and taller and sturdier towers. This is reaffirmed by Ohunakin et al [30], Barter et al [31], Mardones [32], Quinn et al [33], and Langer et al [34]. SPP method is used to evaluate the economic preconditions for an investment in a wind power project.…”

Vision for a sustainable energy transition and decarbonization: A case study of students surveyed at a Chilean University

“…Another relevant aspect of public policies in Chile is the creation of incentives and subsidies for the adoption of clean energy at both the industrial and residential level. The government has implemented financing programs and tax benefits for those who invest in solar, wind, or other renewable technologies [ 64 ]. These measures not only contribute to the reduction of emissions, but also stimulate job creation in the renewable energy industry, strengthening the local and regional economy [ 65 ].…”

Preferred Ratio and Properties of Microfoam Drilling Fluid for Gas Extraction in Soft Coal Seams

“…Coal energy is the foundation and pillar of our nation’s energy structure, accounting for approximately 70% of our total energy consumption. − Its significance in our national economy cannot be overstated as the primary energy source supporting industrial production and the daily lives of urban and rural inhabitants. , While our country actively promotes the development and utilization of new and clean energy sources, coal energy will continue to play a crucial role in the short term. − Given the distinctive characteristic of our coal-dominated energy structure, preventing coal mining accidents holds immense importance, particularly the risks of coal and gas outbursts. , The most effective preventive measure is the drilling and extraction of gas, which not only helps to mitigate hazards but also enables the utilization of gas resources, generating additional economic and social benefits for the mines. − Gas extraction from coal seams represents the most effective approach to gas management, with coal seam drilling being the only means of achieving gas extraction . Gas extraction ensures the safe mining of working faces and allows for the acquisition of gas resources, resulting in supplementary economic and social benefits for the mines. − High-gas mines are the primary target for gas extraction in our country, and data indicates that nearly 95% of the coal seams within these high-gas mines are soft .…”
