Which power generation method uses the heat from beneath the Earth’s surface?
A Biomass
B Wind
C Geothermal
D Solar
Geothermal energy generation uses heat from beneath the Earth’s surface. Hot water or steam extracted from geothermal reservoirs is used to drive turbines connected to generators, producing electricity. It is a renewable and sustainable energy source.
What is the primary energy source for biomass power plants?
A Organic material
B Water
C Coal
D Wind
Biomass power plants use organic materials such as wood, agricultural waste, or other plant-based materials to generate heat. The heat produced is used to create steam, which drives turbines to generate electricity.
Which of the following is NOT considered a renewable energy source?
A Biomass
B Wind
C Geothermal
D Natural gas
Natural gas is a fossil fuel and is not considered a renewable energy source. Unlike geothermal, biomass, or wind, natural gas produces greenhouse gas emissions and is non-sustainable in the long term.
What does biomass energy production primarily rely on?
A Wind
B Combustion
C Radiation
D Fission
Biomass energy production relies on the combustion of organic materials, such as wood, agricultural residues, or waste. The combustion process produces heat, which is used to convert water into steam, driving turbines to generate electricity.
Which renewable energy source utilizes volcanic activity for power generation?
A Tidal
B Solar
C Geothermal
D Wind
Geothermal energy harnesses the heat generated by volcanic activity beneath the Earth’s surface. This heat is accessed by drilling into geothermal reservoirs, where steam is used to drive turbines and produce electricity.
Which biomass material is commonly used for electricity generation?
A Solar panels
B Wood
C Wind
D Water
Wood is one of the most commonly used materials for biomass energy generation. It is burned to produce heat, which is then used to create steam that drives turbines for electricity generation.
What is the primary advantage of geothermal energy over other renewable sources?
A Constant availability
B No emissions
C Low cost
D High efficiency
Geothermal energy has the significant advantage of being available 24/7, regardless of weather conditions or time of day. Unlike solar or wind energy, it is not intermittent and can provide a constant power supply.
In biomass energy production, what is typically burned to generate electricity?
A Coal
B Organic waste
C Uranium
D Water vapor
Biomass power plants burn organic waste such as wood chips, agricultural residues, or other plant-based materials to generate heat. The heat turns water into steam, which drives turbines to generate electricity.
Which process occurs in a geothermal power plant to produce energy?
A Chemical reaction
B Solar absorption
C Wind conversion
D Heat conversion
In a geothermal power plant, heat conversion occurs when steam or hot water from the Earth’s subsurface is used to drive turbines connected to generators. This process converts thermal energy into electrical energy.
What is a disadvantage of geothermal energy production?
A Wind dependency
B Intermittent supply
C High initial cost
D High pollution
Geothermal energy has a high initial cost due to the drilling and infrastructure required to access geothermal reservoirs. While the energy production is sustainable, the upfront investment can be significant compared to other renewable sources.
Which type of energy is typically produced by the combustion of biomass materials?
A Kinetic energy
B Thermal energy
C Solar energy
D Nuclear energy
Biomass combustion primarily produces thermal energy. The burning of organic materials generates heat, which is then used to produce steam. This steam drives turbines connected to generators, converting thermal energy into electricity.
Which of the following is a key factor in determining the efficiency of biomass power plants?
A Ocean currents
B Solar radiation
C Wind speed
D Fuel quality
The efficiency of biomass power plants depends largely on the quality of the fuel used. Higher-quality biomass, such as dry wood or agricultural residues, burns more efficiently and produces more energy, improving overall plant performance.
Which of the following is a form of geothermal energy?
A Hot springs
B Hydropower
C Wind farms
D Solar panels
Hot springs are a form of geothermal energy. They occur when water is heated by geothermal activity beneath the Earth’s surface. This heat can be harnessed for electricity generation or direct heating purposes.
Which material is commonly used in the construction of biomass power plants?
A Metal
B Uranium
C Organic waste
D Water
Biomass power plants commonly use organic waste materials such as wood chips, agricultural by-products, or municipal solid waste. These materials are burned to produce heat, which drives turbines for electricity generation.
What is the environmental impact of biomass energy production?
A Water pollution
B Lower emissions
C High emissions
D High land use
Biomass energy production typically results in lower emissions compared to fossil fuels. While it does produce some emissions during combustion, it is generally considered cleaner and more sustainable than coal or natural gas, especially when using waste materials.
