1.充足、安全、清洁的能源供应是经济发展和社会进步的基本保障。2.开发利用可再生能源是保护环境、应对气候变化的重要措施。 3.可再生能源的开发利用主要是利用当地自然资源和人力资源,对促进地区经济发展具有重要意义。4.目前的开发成本仍然较高，这主要是因为可再生能源的能量密度大多数比较低。5.可再生能源要比传统能源很加的清洁、环保。
相比之下，1.传统能源在人们的眼中往往是污染源之一，它造成了很多的环境问题，比如全球变暖、酸雨……2.它是不可再生的，不符合可持续发展理念。3.尽管如此，它确实有成本低、能源密度高的优点，它仍旧占当今能源组成很大的百分比。

結果 (英文) 1:

1. the supply of adequate, safe, clean energy economic development and the basic guarantee of social progress. 2. the development and utilization of renewable energy is an important measure for protecting the environment, combating climate change. 3. is the use of local renewable energy development and utilization of natural resources and human resources is of great significance to promote regional economic development. 4. development costs still high, this is mainly because most renewable energy density is relatively low. 5. renewable energy than traditional sources of energy and clean and green.By comparison, 1. traditional sources of energy in people's eyes tend to be one of the sources, it caused many environmental problems such as global warming, acid rain ... ... 2. it is not renewable, not consistent with sustainable development principles. 3. Nevertheless, it does have the advantages of low cost, high energy density, it still accounts for a large percentage of today's energy.

結果 (英文) 2:

1. sufficient, safe, clean energy supply is the basic guarantee for economic development and social progress. 2. The development and utilization of renewable energy sources is an important measure to protect the environment, respond to climate change. 3. The development and utilization of renewable energy sources is the use of local natural resources and human resources, to promote regional economic development is important. 4. The current development costs are still high, mainly because most of the energy density of renewable energy is relatively low. 5. clean renewable energy than traditional energy sources are added, and environmental protection.
In contrast, a traditional energy sources in the eyes of the people is often one of the sources of pollution, it causes a lot of environmental problems such as global warming, acid rain ...... 2. It is non-renewable, do not meet the concept of sustainable development. 3. Nevertheless, it really low cost, high energy density advantages, it still accounts for a large percentage of today's energy composition.

結果 (英文) 3:

1 adequate, safe and clean energy supply is the basic guarantee for economic development and social progress. 2 the development and utilization of renewable energy is an important measure to protect the environment and to deal with climate change. 3 the development and utilization of renewable energy resources is mainly to use local natural resources and human resources, to promote regional economic development is of great significance. 4 the current development costs are still higher, mainly because the energy density of renewable energy is relatively low. 5 renewable energy than the traditional energy is very clean, environmental protection.In contrast, 1 of the traditional energy in people's eyes is often one of the sources of pollution, it caused a lot of environmental problems, such as global warming, acid rain...... 2 it is not renewable, does not conform to the concept of sustainable development. 3 nevertheless, it does have the advantages of low cost, high energy density, it still accounts for a large percentage of today's energy.
