Currently, why is electric cooling used more than gas cooling?
In the United States, most cooling needs in the 1930s and 1940s were provided by gas. By the 1960s, electric chillers began making inroads into the cooling market due to lower cost equipment, low electric rates, and higher efficiency machines. In the 1970s, the use of gas was restricted and electric cooling use continued to increase. By 1990, only 5% of all air conditioning in the United States was provided by gas. However, during the 1980s in Japan, efforts (backed by the Japanese government) were being made to accelerate the development of gas cooling. By 1991, nearly 30% of Japan s air conditioning was provided by gas chillers.
