1. A renewable energy specialist is assessing the feasibility of installing a
solar photovoltaic (PV) system in Maryland. Which factor most directly
influences the annual energy output of the system?
A. Color of solar panels
B. Local solar irradiance levels
C. Type of roofing material
D. Number of electrical outlets in the building
Answer: B
Rationale: Local solar irradiance determines the amount of sunlight
, available, directly affecting the energy production of a PV system
over time.
2. In grid-tied solar PV systems, what is the primary purpose of an
inverter?
A. Store electrical energy
B. Convert DC electricity to AC electricity
C. Increase solar panel efficiency
D. Regulate temperature of panels
Answer: B
Rationale: Solar panels produce direct current (DC), and the inverter
converts it into alternating current (AC) for use in homes and the
grid.
3. Which renewable energy source relies on the kinetic energy of moving
air to generate electricity?
A. Biomass
B. Hydropower
C. Wind energy
D. Geothermal energy
Answer: C
Rationale: Wind turbines convert the kinetic energy of moving air
into mechanical energy and then into electricity.
4. What is the main environmental advantage of using renewable energy
sources?
, A. Higher installation costs
B. Reduced greenhouse gas emissions
C. Increased land degradation
D. Greater dependence on fossil fuels
Answer: B
Rationale: Renewable energy sources produce little to no greenhouse
gas emissions, helping mitigate climate change.
5. In Maryland, Renewable Portfolio Standards (RPS) require utilities to:
A. Eliminate all fossil fuel use
B. Increase renewable energy production
C. Reduce customer energy bills
D. Install solar panels on all buildings
Answer: B
Rationale: RPS policies mandate that a certain percentage of
electricity must come from renewable sources.
6. Which type of biomass energy involves the direct combustion of
organic material to produce heat?
A. Anaerobic digestion
B. Gasification
C. Combustion
D. Fermentation
Answer: C
, Rationale: Combustion is the simplest biomass process, burning
organic material to release heat energy.
7. What is net metering?
A. Charging customers for excess energy use
B. Measuring energy losses in transmission
C. Crediting solar system owners for excess electricity sent to the grid
D. Limiting energy production from renewables
Answer: C
Rationale: Net metering allows system owners to receive credit for
surplus electricity exported to the grid.
8. Which component of a wind turbine captures energy from the wind?
A. Generator
B. Rotor blades
C. Tower
D. Transformer
Answer: B
Rationale: Rotor blades intercept wind energy and convert it into
rotational motion.
9. Geothermal energy systems utilize heat from:
A. The sun
B. The earth’s interior
C. Ocean tides
D. Atmospheric pressure
