Flashcards on Physics of Renewable Energy
Click on the flashcard to see the answer
What is renewable energy?
Energy that is generated from natural resources and can be replenished over time.
What are the advantages of renewable energy?
Cleaner and more sustainable compared to fossil fuels, reduces greenhouse gas emissions, and helps combat climate change.
What are the different types of renewable energy sources?
Solar, wind, hydroelectric, geothermal, and biomass.
How does solar power work?
Solar panels convert sunlight into electricity through the photovoltaic effect.
What is the principle behind wind turbines?
Wind energy is harnessed by wind turbines, which convert kinetic energy from wind into electricity.
What is the role of hydroelectric power in renewable energy?
Water flowing in rivers or falling from dams is used to generate electrical power through turbines.
How does geothermal energy work?
Heat from the Earth's core is harnessed to generate electricity or heat buildings directly.
What is biomass energy?
Energy derived from organic matter, such as plants or agricultural waste.
What is the role of physics in renewable energy systems?
Physics helps understand the conversion, transmission, and storage of energy in renewable systems.
What are some challenges in renewable energy systems?
Intermittency of some sources, energy storage, and initial infrastructure costs.
How does the efficiency of renewable energy technologies compare to fossil fuels?
Efficiency varies, but renewable energy technologies are continuously improving and becoming more competitive.
What is the impact of renewable energy on job creation?
Renewable energy industries contribute to job growth and can stimulate economic development.
What are some global initiatives promoting the use of renewable energy?
Examples include the Paris Agreement, the International Renewable Energy Agency (IRENA), and national policies.
How can individuals contribute to renewable energy adoption?
By using energy-efficient appliances, supporting renewable energy programs, and reducing energy consumption.
What is the future outlook for renewable energy?
Continued growth and advancements in technologies to meet the increasing global demand for clean energy.
