Final answer:
New York City has the highest insolation in the U.S, with approximately 5.75 kWh/m²/day in the southwest desert. Beijing's insolation is likely to be lower than that of New York City due to its higher latitude.
Step-by-step explanation:
The highest insolation for New York City and Beijing can be determined by looking at Figure 13.9, which shows the variation of insolation across the U.S. Although New York City is not specifically mentioned, we can get an idea of the range of insolation values. From the figure, we can see that the highest insolation values in the U.S. are found in the southwest desert, with approximately 5.75 kWh/m²/day.
Beijing is not specifically mentioned in the provided information, but based on general global patterns, it is located at a latitude where insolation values are generally lower compared to locations closer to the equator. Therefore, Beijing's insolation values are likely to be less than those of New York City.
It is important to note that insolation values can vary depending on weather conditions and other factors, so these numbers are an approximation.
