Question

pv allows you to produce electricity—without noise or air pollution—from a clean, renewable resource. a pv system never runs out of fuel, and it won’t increase u.s. oil imports. many pv system components are manufactured right here in the united states. these characteristics could make pv technology the u.s. energy source of choice for the 21st century.
the basic building block of pv technology is the solar “cell.” multiple pv cells are connected to form a pv “module,” the smallest pv component sold commercially. modules range in power output from about 10 watts to 300 watts. a pv system connected or “tied” to the utility grid? has these components:

• one or more pv modules, which are connected to an inverter
• the inverter, which converts the system’s direct - current (dc) electricity to alternating current (ac)
• batteries (optional) to provide energy storage or backup power in case

multiple choice 1 point
how does the author support the claim that pv technology could be a valuable energy source for the us in the 21st century?
by explaining how much it costs the customers.
by explaining the immense need of reliable sunlight.
by explaining the environmental benefits of the system
by explaining how it different pv systems functions.

Explanation:

The text discusses PV (photovoltaic) technology. It mentions that PV allows producing electricity without noise or air pollution (environmental benefits). The claim is about PV being a valuable energy source for the U.S. in the 21st century. Explaining environmental benefits (like being clean - renewable) supports this claim as it addresses a key aspect (sustainability, lack of pollution) that makes it a good energy source.

Answer:

By explaining the environmental benefits of the system.
