Study Notes
Benefits of Wind Energy
- Renewable and sustainable energy source that reduces greenhouse gas emissions.
- Cost-effective compared to fossil fuels; operational costs decrease over time as technology advances.
Geothermal Power Generation
- Utilizes heat from the Earth’s interior to generate steam, which drives turbines to produce electricity.
- Can be used for district heating or direct use applications, providing energy without combustion.
Production of Sound Energy
- Generated by the vibration of objects, creating pressure waves in a medium such as air or water.
- Common examples include musical instruments, bells, and machinery.
Chemical Energy Defined
- Potential energy stored in the bonds of chemical compounds, which can be released during chemical reactions.
- Found in fuels, food, and batteries, enabling processes that power vehicles and living organisms.
Understanding Geothermal Energy
- Captured from the heat stored beneath the Earth’s surface, typically where tectonic activity is present.
- Environmentally friendly, offering baseload power that is less dependent on weather conditions than solar or wind energy.
Sources of Non-Renewable Energy
- Fossil fuels: coal, oil, and natural gas are primary sources.
- Nuclear energy, derived from uranium, is also categorized as non-renewable.
Light Energy Explained
- Form of electromagnetic radiation visible to the human eye, essential for photosynthesis in plants.
- Drives various processes, including solar energy conversion, crucial for sustainable energy solutions.
Biomass Power Generation
- Involves burning organic materials (e.g., wood, agricultural waste) to produce heat.
- The heat generates steam to operate turbines, thus producing electricity, while being considered renewable.
Calculating Energy Efficiency
- Formula: Energy Efficiency = (Useful Energy Output / Total Energy Input) x 100%.
- A measure of how effectively energy is converted into useful work or output, critical for assessing technology performance.
Disadvantage of Geothermal Energy
- Geothermal plants may face high upfront costs and limited availability depending on geographic location.
- Potential environmental concerns, such as land subsidence and water emissions, can arise.
