Hydroelectric Energy Tradeoffs(16)
What is a major advantage of hydroelectric power?
It provides renewable energy, reducing reliance on fossil fuels.
True or False: Hydroelectric plants produce greenhouse gases.
False. They produce minimal emissions compared to fossil fuels.
List two environmental impacts of hydroelectric dams.
- Altered water flow - Displacement of local wildlife
What is one economic benefit of hydroelectric power?
Low operational costs after initial construction.
Fill in the blank: Hydroelectric power relies on the ____ of water.
movement
Compare hydroelectric power to fossil fuels.
Hydroelectric is renewable, eco-friendly; fossil fuels are finite, polluting.
What is a significant disadvantage of hydroelectric energy?
Potential for habitat destruction and ecosystem disruption.
Cause → Effect: What happens when water is dammed for hydroelectric power?
Causes flooding upstream and can alter local ecosystems.
How can hydroelectric power generation affect local communities?
It can displace residents and change local economies.
What is one way hydroelectric power contributes to energy storage?
Pumped storage systems store energy by moving water between reservoirs.
True or False: Hydroelectric plants require massive amounts of land.
True. Dams can inundate large areas of land.
Which country is a global leader in hydroelectric power?
Brazil, due to its extensive river systems.
What is a potential risk associated with hydroelectric reservoirs?
They can become breeding grounds for mosquitoes, increasing disease.
Identify one challenge in hydroelectric energy production.
Dependence on consistent water flow and rainfall patterns.
Fill in the blank: Hydroelectricity can help in ____ energy management.
peak load
What is the relationship between hydroelectric power and irrigation?
Hydroelectric dams can provide water for agricultural irrigation.
Geothermal Energy Tradeoffs(16)
What is geothermal energy?
Geothermal energy is heat derived from the Earth's internal resources. It utilizes steam or hot water from below the Earth's surface to generate electricity or for direct heating.
Pros of geothermal energy?
- Renewable source - Low emissions - Reliable and stable energy supply - Reduces dependence on fossil fuels
Cons of geothermal energy?
- High initial costs - Limited to certain geographical areas - Risk of induced seismicity - Potential for water contamination
True or False: Geothermal energy can cause earthquakes.
True. Induced seismicity can occur from drilling and fluid injection, leading to small earthquakes.
Fill in the blank: Geothermal systems can achieve efficiencies of up to ____%.
10% to 20%.
What are the main types of geothermal plants?
1. Dry steam plants 2. Flash steam plants 3. Binary cycle plants
How is geothermal energy used for heating?
Through geothermal heat pumps that transfer heat from the ground to buildings for space heating.
Cause → Effect: Drilling wells for geothermal energy leads to _____.
Potential groundwater contamination.
Comparison: Geothermal vs. solar energy.
Geothermal is more reliable (constant energy) but less geographically widespread than solar.
What is the role of geothermal heat pumps?
They are used for heating and cooling by extracting heat from the ground in winter and transferring heat back into the ground in summer.
True or False: Geothermal energy is only viable in volcanic regions.
False. While volcanic areas are ideal, geothermal energy can be harnessed in various regions with suitable geological conditions.
What is the approximate cost range for geothermal energy installation?
5,000 per kilowatt.
How does geothermal energy impact land use?
It requires less land compared to solar or wind installations, but specific sites can disrupt local ecosystems.
What is one major environmental benefit of geothermal energy?
It emits significantly lower greenhouse gases compared to fossil fuels.
Fill in the blank: Geothermal plants can produce electricity from temperatures as low as ____°F.
About 300°F.
What is a major economic consideration of geothermal energy?
High upfront capital costs vs. low operating costs.
