- Slide: 1
- Define your energy source. Hydroelectric power is the electricity generated by harnessing the energy from flowing or falling water. This is typically achieved through the construction of dams on large rivers, where water flow is directed through turbines that convert kinetic energy into mechanical energy, which then generates electricity.
- Is your energy source renewable or nonrenewable? Explain why.Hydroelectric power is a renewable energy source. Water is continuously cycled through the hydrological (water) cycle, meaning that as long as there is precipitation and a sufficient water supply, hydroelectric power can be generated sustainably. It does not deplete natural resources or exhaust water supplies, making it environmentally sustainable in the right contexts.
- Describe how your energy source is obtained. How do we get it?Water Flow: River water is captured, typically using a dam to create a reservoir.Turbine Activation: When water is released from the reservoir, it flows through turbines installed at the dam.Electricity Generation: As the turbines rotate due to the movement of water, they drive generators that produce electricity.
- What areas of the world are more likely to use this energy source? Why is it more likely that some areas will use this energy source, while other areas might not? Countries and regions with abundant water resources and large river systems are more likely to use hydroelectric power
- Slide: 2
- Discuss how the use of this energy source impacts our environment. Altering waterways and local habitats. Affecting fish populations through blocked migration routes. Changing the natural sediment flow in rivers, which can degrade downstream ecosystems. Proper management practices, such as fish ladders and environmental flow assessments, are crucial to mitigate these effects.
- Do you think that the use of your energy source will increase or decrease in the future? Why? Use data to support your answer. Environmental Concerns: Increasing awareness of ecological impacts may slow new dam constructions. Competition with Other Renewables: Advances in solar and wind power technologies have made them more appealing in some contexts. Investment in Existing Infrastructure: Many countries will focus on improving and upgrading existing hydroelectric plants rather than building new ones. According to the International Energy Agency (IEA), hydropower is expected to continue playing a significant role in global renewable energy generation, especially in developing regions where new capacity may be needed. As of 2021, hydropower accounted for about 16% of the world’s electricity generation. The transition to renewable and low-carbon energy sources will keep hydroelectric power as a vital component but may not see substantial growth compared to other renewable sources. In conclusion, while hydroelectric power remains a cornerstone of renewable energy for many regions, its future expansion will depend on balancing energy needs with environmental sustainability and social considerations.
- Slide: 3
- Discuss 3 advantages of using this type of energy. Low Greenhouse Gas Emissions: Hydroelectric plants produce very minimal greenhouse gases compared to fossil fuel energy sources. Reliable and Flexible: Hydroelectric power can adjust to changing energy demands, making it a stable and reliable energy source. Multiple Uses: Hydropower often creates reservoirs that can be used for recreation, irrigation, and water supply, offering various community benefits.
- Describe the process by which your energy source is used. How do we get energy from it? Water Storage: Creating a reservoir behind a dam to store potential energy. Flow Regulation: Water is released to flow through turbines when energy is needed. Mechanical to Electrical Energy: The moving water causes turbine blades to spin, generating mechanical energy, which is converted to electrical energy through an electrical generator.
- Discuss 3 disadvantages of using this type of energy. Environmental Impact: Dams can disrupt local ecosystems, affect fish migration, and alter river habitats. Displacement: Building large reservoirs often requires the relocation of communities and can inundate land. Dependence on Weather Patterns: Droughts or changes in rainfall (due to climate change) can significantly reduce water flow, impacting energy generation
- In what ways do we depend on this source for energy? What do we use it for? Electricity Generation: It supplies power for residential, commercial, and industrial use. Irrigation and Water Supply: Reservoirs can help manage water resources for agricultural and domestic use. Flood Control: Dams can regulate river flow, preventing flooding in adjacent areas.
