Question

the costs to generate solar power continue to fall, according to a 2019 report published by the international renewable energy agency. which of the following solar power technologies has experienced fluctuating but decreasing cost per kilowatt hour since 2010, and how do you know? choose 1 answer: a photovoltaic (pv), because the 2021 cost was below the cost of concentrated solar. b concentrated solar power (csp), because the 2010 cost was below the cost of photovoltaic and the 2011 cost was above that of photovoltaic. c concentrated solar power (csp), because the cost rose and fell irregularly between 2010 and 2021. d photovoltaic (pv), because the 2010 cost was above the cost of concentrated solar and the 2011 cost was below that of concentrated solar.

Explanation:

Step1: Analyze the graph

By observing the graph, we can see the trends of photovoltaic (PV) and concentrated - solar power (CSP) costs over time from 2010 - 2021.

Step2: Check the cost trends

The cost of concentrated solar power (CSP) has fluctuated (risen and fallen irregularly) while also showing a decreasing overall trend from 2010 to 2021. The cost of photovoltaic (PV) has also decreased but has not shown the same degree of fluctuation as CSP.

Answer:

C. Concentrated solar power (CSP), because the cost rose and fell irregularly between 2010 and 2021.
