Rare high temperature weather occurred in many countries in the northern hemisphere, which caused drought and forest fires and brought disasters to some countries. Human activities are the main cause of global warming. There is an urgent need to use more renewable energy to protect the ecological environment, and the application of solar energy is changing the lifestyle of human beings.
In Dezhou, Shandong Province, local enterprises are trying to cook food with solar energy. In the Sun Valley of Ming Dynasty in China, dozens and hundreds of kinds of solar food appeared one by one. Although cooking was done outdoors, there was no smoke. Nearly a thousand solar kitchens can concentrate on cooking. As long as the food is put into the cylindrical equipment in the kitchen, you can cook fresh and delicious delicacies without naked flame, fuel such as coal, firewood and gas, and without producing lampblack.
Chairman of Huang Ming Group said, "The solar micro-kitchen can cook porridge, cook and barbecue. Barbecue needs high temperature, and porridge has heat preservation requirements. With the help of Antarctic expedition team, the vacuum tube technology of solar micro kitchen has been broken through. I hope that the solar micro kitchen can create a smoke-free and pollution-free cooking mode for human beings and set off a revolution in cooking methods around the world. "
According to the statistics of the World Health Organization, "every year, because solid fuels are cooked and heated on open stoves with open flames or chimneys, indoor air pollution leads to an increase in people's risk of illness." In addition, nearly 2.4 billion people in the world rely on wood for heating, boiling water and cooking, and 65.438+0.3 million hectares of forests are cut down every year.
The use of solar energy can be immersed in people's daily necessities, textiles, medical care, construction, transportation and other aspects. Take the barbecue food stall as an example. The concentration of benzopyrene in the street where the barbecue site is concentrated is 60 times to 1 10 times higher than the national ambient air quality standard, while the inhalable particulate matter is more than ten times higher than the national standard, and the emission concentration of suspended particulate matter is several times higher than that of the boiler. If the cooking methods in the kitchen can be changed in the future, it will help to improve the air quality and reduce the pollution of PM2.5 to the environment, thus protecting human health.
As a practitioner who has worked in the field of solar energy for more than 20 years and the vice chairman of the 3rd International Solar Energy Society, Huang Ming told this reporter that solar energy can generate electricity, provide heat and desalinate seawater. Compared with cities, it can be more widely used in rural areas and open areas, and can change people's lifestyles in the future, thus changing the world. I hope everyone will work together for their own living environment.
The application of solar energy is everywhere. A Belgian athlete started from Lyon, France, participated in the "Belt and Road" Sun Tour Cycling Rally, rode a solar bicycle, and first arrived in Guangzhou, China. It took 45 days to cross the Eurasian continent 12000 km. In Shandong, the solar Dezhou town opened to the outside world on August 4th, and held the China International Solar Decathlon, with a total of 19 teams from 8 countries and regions participating. Each group will build a solar house with the goal of permanent use.
