The U.S. excels in cultural assimilation by incorporating various aspects of different cultures, such as food, music, literature, and religion, into its society. This creates a diverse environment where people from various backgrounds can find a sense of belonging and contribute to the nation's cultural identity. The U.S. also provides opportunities for immigrants to learn English and acquire skills, which further enhances their assimilation into American society.
The U.S. is a leading user of air conditioning, with 88% of households having AC in 2020. This is due to the necessity of cool air in regions like the Southwest and Southeast2. However, the widespread use of AC contributes to high energy consumption and raises concerns about sustainability. Globally, China has the most AC units in use, but countries like Japan focus on energy-efficient solutions. In Europe, AC use is less common, particularly in Germany and Switzerland.
