20世纪,以煤炭、石油、天然气等化石燃料为动力的工业文明飞速发展。人们在享受现代文明所创造的优越的物质生活的同时,能源和环境两大危机却已不期而至。按照目前人类活动所需的能源消费水平,再过一百多年,地球在50万年漫长的地质年代所形成的煤炭、石油、天然气等常规化石能源将要消耗怠尽;而与此同时燃烧化石燃料要向大气中排放大量废气,使大气变浊,造成酸雨剧增,气候变暖,洪涝干旱灾害频繁,臭氧层被破坏。在当前全球能源和环境向人类亮出“黄牌警告”之时,开发新能源已成为人类发展中的紧迫课题。谁能最先占领可再生能源利用的先机,谁就将在未来全球经济发展中占据有利地位。可再生能源的发展既解决了能源替代问题,又为农业资源、自然资源提供了一个新的发展空间,使其产业化、现代化,变无用为有用,清洁、环保,增加其价值和使用价值,既可推动农业与工业的结合,又可促进环境与社会的和谐与可持续发展。
In the 20th century, industrial civilization driven by fossil fuels such as coal, oil, and natural gas developed rapidly. While people enjoy the superior material life created by modern civilization, the two major energy and environmental crises have unexpectedly arrived. According to the current level of energy consumption for human activities, in more than one hundred years, the conventional fossil energy resources such as coal, oil, and natural gas formed by the Earth in the 500,000-year geological period will be exhausted; at the same time, fossils will be burned. The fuel must emit large amounts of exhaust gas into the atmosphere, causing the atmosphere to become turbid, causing a dramatic increase in acid rain, a warming climate, frequent floods and droughts, and destruction of the ozone layer. When the current global energy and environment show people a “yellow card warning”, the development of new energy has become an urgent issue in human development. Whoever can occupy the first opportunity for the use of renewable energy will have an advantage in the future development of the global economy. The development of renewable energy not only solves the problem of energy substitution, but also provides a new space for the development of agricultural resources and natural resources, makes it industrialized and modernized, becomes useless as useful, clean, environmentally friendly, and increases its value and use value. It can not only promote the integration of agriculture and industry, but also promote the harmony and sustainable development of the environment and society.
