FAQs about Renewable Resources of Energy
-
What is the working principle behind solar photovoltaic cells, and how do they convert sunlight into electricity?
Solar photovoltaic cells, also known as solar panels, utilize the photovoltaic effect to convert sunlight into electricity. When sunlight strikes the surface of the solar cells, it excites electrons, creating an electric current. The cells are typically made of semiconductor materials, such as silicon, which have the ability to generate an electric charge when exposed to light. This direct conversion of sunlight into electricity makes solar panels a reliable and sustainable source of renewable energy.

How does the power output of wind turbines vary with wind speed, and how do advanced control systems optimize energy capture?
The power output of wind turbines is directly proportional to the wind speed. As the wind speed increases, the energy captured by the rotor blades increases exponentially. Wind turbines are equipped with advanced control systems that optimize the turbine’s orientation and blade pitch to maximize energy capture at varying wind speeds. These control systems adjust the angle of the rotor blades based on real-time wind data, ensuring efficient energy conversion and preventing damage during extreme wind conditions.

What are the different types of geothermal power plants, and how do they harness the Earth’s heat for electricity generation?
Geothermal power plants come in various configurations, including dry steam, flash steam, and binary cycle power plants. Dry steam power plants utilize steam directly from underground reservoirs to drive turbines and generate electricity. Flash steam power plants, on the other hand, extract hot water from geothermal reservoirs and allow it to flash into steam to drive turbines. Binary cycle power plants use a secondary fluid with a lower boiling point than water to generate steam for turbine operation, making them suitable for lower temperature geothermal sources.

How does hydropower energy deal with the fluctuating water flow rates, and what are the design considerations for different types of hydroelectric power plants?
Hydropower energy systems need to cope with varying water flow rates, especially in run-of-river and small-scale hydroelectric power plants. Design considerations include the use of turbines with variable pitch blades to adjust to changing flow rates and the implementation of reservoirs or pumped storage systems to store excess energy during periods of high water flow. Additionally, efficient water management strategies are employed to ensure a constant and stable supply of water for power generation.
