Case Description:
Renewable energy sources, such as solar, wind, hydro, and biomass, are gaining
popularity due to their sustainability and lower environmental impact. These
energy sources are replenished naturally and can be used without depleting the
Earth's resources. For instance, solar panels convert sunlight into electricity,
while wind turbines convert wind energy into mechanical power.
MCQs:
Which of the following is NOT a renewable energy source?
What is the main advantage of using renewable energy sources?
How does a solar panel convert sunlight into electricity?
Wind energy is harnessed using which of the following devices?
Case Description:
Fossil fuels, such as coal, petroleum, and natural gas, are formed from the
remains of ancient plants and animals over millions of years. They are
non-renewable resources, meaning they cannot be replenished in a human
timescale. Fossil fuels are widely used for electricity generation, heating, and
powering vehicles but contribute significantly to environmental pollution.
MCQs:
Which of the following is a fossil fuel?
What is the primary environmental concern associated with burning fossil fuels?
Which of the following processes is used to extract oil from beneath the Earth's surface?
Which fossil fuel is primarily used in electricity generation?
Case Description:
Hydroelectric power is generated by harnessing the energy of flowing water,
typically from rivers or dams. Water is stored in reservoirs, and when released,
it flows through turbines, generating electricity. This form of energy is
renewable and considered clean, as it produces no direct emissions.
MCQs:
What is the primary energy source for hydroelectric power plants?
Which of the following is a benefit of hydroelectric power?
What is the main environmental concern associated with the construction of dams for hydroelectric power?
How does water flow in a hydroelectric power plant generate electricity?
Case Description:
Solar energy is harnessed by converting sunlight into electricity using
photovoltaic cells or solar thermal systems. It is a clean and abundant source
of energy, ideal for both residential and industrial applications. With
advancements in technology, solar panels have become more efficient and
affordable, leading to a significant increase in their adoption worldwide.
MCQs:
What technology is primarily used to convert solar energy into electricity?
Which of the following is NOT a benefit of solar energy?
What is the main component of a photovoltaic cell?
How can solar energy be used besides electricity generation?
Case Description:
Biomass energy is derived from organic materials such as plant and animal waste.
It can be converted into electricity, heat, or biofuels. Biomass is considered
renewable because the materials used can be replenished. However, its production
and use can impact land use and require careful management to minimize
environmental effects.
MCQs:
Which of the following is considered biomass?
What is the process of converting biomass into biofuel called?
What is one disadvantage of using biomass energy?
Biomass can be used to produce which of the following?
