Asking ChatGPT 4, an AI chatbot, to write a 100-word email might take just a few seconds. But have you ever wondered about the environmental influence of this technology? The rapid growth of AI is raising concerns. Many people realize that the tool comes with hidden costs, especially the large amount of energy used by digital services.
One of the main problems is the"water footprint", the total water the AI chatbot uses in its lifetime.AI depends on data(数据) centers, which house servers that store and manage data. Once turned on, the servers produce heat. To cool them down, engineers use pipes to bring in cold water from cooling towers to take away the heat.
Data centers operate around the clock, making them very"thirsty". According to The Washington Post, ChatGPT 4 needs about 519 milliliters of water, or a little more than a bottle for every 100-word email. Each year in the US, ChatGPT 4 uses over 435 million liters of water just for emails - enough to support a regular US family for 1,050 years.
Meanwhile, data centers are"hungry" for electricity. Writing a 100-word email requires 0.14 kilowatt-hours of electricity, which can power 14 light bulbs for one hour. Yearly, ChatGPT 4 uses up over 120,000 megawatt-hours(兆瓦时) of power just to help write emails. This is enough to support all homes in Washington DC for 20 days.
Now, businesses are looking for different ways to make AI more environmentally friendly. Microsoft uses cold metal plates with cold water to cool machines. Clean energy is also helpful; for example, Tencent's data center is powered by solar energy. Another company, Google, uses developed cooling systems that rely on outside air to cut down cooling needs.
At the 19th Asian Games in Hangzhou, people cheered when China's Tong Xin finished her taijijian moves. On Sept 24, she won the women's raijiquan and taijijian all-round gold. The Asian Games have more events than the Olympic Games. These events, like raijijian, are from different countries and cultures across Asia. This makes the Asian Games interesting. Here are some of the special sports.
Special Asian Sports |
Wushu Chinese wushu first came about in the Shang and Zhou dynasties (16th century-256 BC). It is an important part of Chinese culture. Modern wushu has two parts: taolu and sanda. Tong's slow but strong actions with her sword(剑) showed perfectly Chinese wushu's beautiful mix of soft and hard moves. Wushu was first included in the Asian Games in 1990. |
Kabaddi(卡巴迪) Kabaddiis a folk sport from India. It has a history of more than 4,000 years. The sport looks like the game "eagle catching chickens". You only need a place to play it, nothing else. The place should be 13 meters long and 10 meters wide. |
Sepak takraw(藤球) Sepak takraw first became popular in Southeast Asia. It is like the traditional Chinese game of shuttlecock kicking(踢毽子). Players need to use their feet, head, knees and chest(胸) to move the ball. It is also called "kick volleyball". |
