Explanations:The question asks about the major contributor to electricity supply in a park using renewable energy technology. The correct answer is Solar Photovoltaic (PV) technology. To understand why Solar PV is the major contributor, we need to consider the characteristics and practicality of each renewable energy technology in a park setting.
Solar PV technology involves the use of solar panels to convert sunlight directly into electricity. Solar panels are highly efficient and can be installed in various locations within a park, such as rooftops of buildings, open spaces, or even integrated into the design of park structures. The reliability of solar PV is high, as it can generate electricity during daylight hours, which is when parks are typically most active. Additionally, solar panels require minimal maintenance and have a long operational life, making them a cost-effective and sustainable solution for park infrastructure.
Hydro power, on the other hand, requires a significant water source and infrastructure, such as dams or turbines, to generate electricity. This type of setup is not feasible in most park environments due to the lack of suitable water resources and the potential environmental impact of such installations. Therefore, hydro power is not a practical option for electricity supply in parks.
Wind energy involves the use of wind turbines to generate electricity. While wind energy can be a viable option in certain locations, parks typically do not have the necessary wind speeds or space to accommodate large wind turbines. Wind turbines also require regular maintenance and can be noisy, which is not ideal for a park setting. Thus, wind energy is not a major contributor to electricity supply in parks.
Biomass gasifiers use organic material, such as wood chips or agricultural waste, to generate electricity. While biomass can be a renewable energy source, it requires a steady supply of organic material and a complex processing system. This makes it impractical for a park setting, where the logistics of maintaining a consistent supply of biomass and the infrastructure for processing it would be challenging. Therefore, biomass gasifiers are not a major contributor to electricity supply in parks.
In summary, Solar PV technology is the major contributor to electricity supply in parks due to its reliability, ease of installation, and suitability for park environments. The other renewable energy technologies, such as hydro power, wind energy, and biomass gasifiers, are less practical and less reliable for electricity supply in parks compared to solar PV.
