As a major exporter of large quantities of raw materials to China, Australia supports China’s high-carbon economy. Australia has been the first major country to achieve economic recovery, in part due to its trade relations with China. Both Australia and the United States, among high energy consuming countries of the world, have very high rates of energy consumption at the equivalent of around nine tons of coal per capita (Russia has the highest with 9.5 tons).

Despite their alliance with America on national defense (although now becoming suspicious of the U.S commitment to security), Australia does not stand by America on the idea of low-carbon economies. If China were to accomplish a conversion to a low-carbon economy, this would result in fewer exports of coal and ore from Australia to China. Also, the application of low-carbon technology may reduce China's purchases of Australia's natural gas (China's Guangdong Province uses Australian gas). Australia also has developed clean coal electricity generation technology in cooperation with China. Every year, China sends many students to study in Australia.

Obama suggests to emerging nations that they establish low-carbon economies, but how does one balance conservation and growth in a fair way? Should developed countries use less or should emerging nations incrementally reduce use? Regardless, China has been working hard on reducing its energy consumption.

We Should Take an Optimistic
Look at Obama’s Viewpoint


First, China’s economy is rapidly growing with low energy consumption (two tons of standard coal per capita annually), but higher-carbon usage has begun to create serious problems such as environmental pollution and mining accidents. Air pollution is very severe in China, especially in many metropolitan areas. Beijing’s air was much cleaner due to restrictions of car use during the Olympics. China’s per capita water resource [usage] is only half of the world’s average, but a large number of rivers and lakes are polluted. Thermal power generation has triggered severe acid rain, destroying forests and harming the biosphere.

Second, massive imports of crude petroleum, gas, and coal bring huge uncertainty to China’s economy and national security. This is not only because China’s navy is not strong enough to protect its transport lines; as China becomes more and more reliant on energy-exporting countries such as Russia, China then relies on those countries more than they rely on China, forcing China to be involved in regional conflicts and to bear excess responsibilities.

China imports 200 million tons of crude oil per year that is mostly used by transport vehicles. If China had private cars just like America, China would have to expand oil imports to 800 million tons. For China, which has a population larger than the U.S. by 100 million, a low-carbon economy is the way to reach the U.S. standard of living. The economy is running out of oil reserves.

Third, a low-carbon economy is an economic growth point after the financial storm, and China matter-of-factly has had a low-carbon lead over other economies. Developing a low-carbon economy, therefore, is not only to China’s overall advantage, but also is advantageous for its security. China is abundant in the natural resources required for low-carbon technology.

China exports solar water heaters worth billions of U.S. dollars, and annually supplies developed countries with millions of electric bikes and motorbikes with a value of nearly $4 billion. China’s advanced electric car system can be sold to developing nations. By using cheap lead-acid batteries or nickel-metal hydride batteries, an electric car only costs at around 10 thousand Chinese yuan. An electric car’s energy consumption is less than 100 yuan per month, which is far cheaper than regular fuel vehicles. It can run at 40 kilometers (24.9 miles) per hour with 100 kilometers (62 miles) on one charge. If applied in counties and towns, local battery changing stations can be built to help electric car owners.

For large cities, the long-distance routes and expensive compatible batteries result in a high price for appropriate electric-only vehicles that will cost hundreds of thousands of yuan, despite utilization of the BYD iron lithium battery, which is large and heavy but cheap, safe, and has a long life. Hybrid electric vehicles are going to be developed that require cheap small-size lithium batteries, lead-acid batteries, or fuel cells.

Cheap triple-cylinder fuel engines will then be created to further reduce fuel costs and lower oil consumption to 2 liters (1/2 gallon) per 100 kilometers (62 miles). The government can levy a smaller sales tax on purchasing hybrid vehicles, making their price close to that of regular cars. In certain developing phases, hybrid vehicles can be set-up as the standard motor configuration, which can reduce the oil consumption of each car to one-fifth of its previous consumption, massively reducing oil imports.

The use of electric cars — which should be a top priority — could decrease imports of natural gas that buses rely on. Electric cars are powerful and could possibly use lithium batteries. Charging or changing stations would be cheaper and safer than gas stations.

About 70 percent of current battery power comes from thermal power. Car parks should set-up facilities to charge cars at night, such as the electro-trough, so that there is no increase in energy consumption. Wind, solar, and optical power charging systems should also be developed — not only to benefit the automotive industry, but also to significantly stimulate the entire economy.

Developing new energy and a low-carbon economy requires solutions with various technical problems, such as energy systems and materials, which can stimulate high-end technology development.

Fourth, a high-carbon lifestyle may not prevail outside of the United States and Australia, where not everyone likes driving SUVs. For instance, the younger generation in Europe and Japan are not keen on buying cars. Even in America, it differs in various places. New Yorkers, for example, prefer the subway to cars as day-to-day transport, while cars (even fashionable eco-friendly vehicles) are essential for Los Angeles since automobile usage dictates city planning and design.


澳美不都是一条心- 积极看奥巴马的言论
[2644] (2010-05-17)
澳大利亚是中国高碳经济的支持者,中国进口不少澳大利亚的原料,因此澳大利亚是世界第一个恢复经济的主要国家。澳大利亚和美国生活方式在世界上人均消耗能源方面是排在前面年人均近9吨标准煤(俄罗斯是世界最高的是9.5吨)。在国防上,澳大利亚和美国是盟国(现在对美国的安全承诺也开始怀疑),但是低碳经济上,澳大利亚和美国可不是一条心的,中国搞低碳经济会少买澳大利亚的煤和矿石,因为使用低碳技术也可能少买澳大利亚的天然气(广东省天燃气用澳大利亚)。澳大利亚也开发出清洁煤发电技术与中国合作。中国每年不少学生去澳大利亚留学。
  奥巴马建议新兴国家走低碳之路,存量和增量怎样公平?是发达国家少用还是新兴国家少增加使用?不管如何,中国还是非常努力要完成降低能耗的计划。
  应该积极观点看奥巴马观点。
  首先,中国经济发展很快,现在人均能耗还不高(年2吨标准煤),但是高碳使用带来环境污染,矿难等等问题还是很严重的。中国大气污染很严重,特别是很多大城市。北京奥运时限制汽车,空气就干净很多。中国人均水资源只有世界平均水平的一半,但是有大量江河湖泊被污染。火力发电带来严重酸雨,毁坏森林,破坏了生物圈。
  第二,中国进口大量原油、天然汽和煤炭,给经济和国家安全带来很大不确定性。中国海军实力还不够保护自己交通线。中国也越来越依赖能源输出国,俄国就认为中国更需要俄国,要在世界战略上逼迫中国就范,卷入地区冲突之中,承担过多义务。
  中国每年进口2亿吨原油,多数是用在交通工具上,如果与美国一样多私家车,要增加进口到8亿吨石油。而中国人比美国人口多了十亿人,要达到美国生活水平要另辟蹊径,低碳经济就是一条路。而且,现在经济石油储量不多了。
  第三低碳经济是后经济危机之后是经济增长点,中国其实是低碳经济领先国,是发挥了自己的优势,而且获得安全优势。低碳技术上所需要的稀土资源是中国的优势。
  中国是世界上太阳能热水器出口国有数十亿美元,每年向发达国家出口上百万辆电动自行或者摩托车,近40亿美元。中国成熟的电动车系统可以出口到发展中国家:使用比较便宜的铅酸蓄电池或者镍氢电池,整车价格万元级,而且成本比燃油车便宜得多,每个月不过几十元,每小时跑40公里,充一次电跑100公里,在县镇使用,建立本地电池更换站,方便车主。
  大城市中,路途远,适合的电池昂贵,适合的纯电动车比较贵,即使使用安全性高,寿命长,价格低的比亚迪铁锂电池(体积和重量比较大)的汽车也要十几万元。就要发展混合动力车了,配小的锂电池或者铅酸电池,或者燃料电池,增加成本不多,再使用低成本的三缸燃油发动机以减低成本,使得每百公里耗油量降到2升左右。政府可以为混合动力车购买减购置税,使得与普通车价格接近。发展到一定阶段把混合动力成为汽车标准配置。这可以使得每部汽车石油消耗量减少到原来的五分之一。大大减少石油进口。
  使用电动车可以减少天然气进口。公共汽车现在依赖进口的天然气,优先考虑使用电动车,功率比较大,可能用锂电池,电池充电站或更换电池站成本比天然汽站低,也安全得多。
  现在电池用的电力,70%也是火力发电, 在晚上用电波谷充电,不会增加能源消耗量,在停车场就设立充电设备。发展风力,太阳能热电力和光电力充电系统,就不只对汽车工业了,对整个经济带动更大。
  发展新能源和低碳经济要解决大到能源系统,小的材料的技术问题,刺激高科技的发展。
  第四 美国和澳大利亚高碳生活方式可能不再流行,不是都喜欢开着SUV,例如欧洲和日本年青一代就不再热衷于买车。就是美国不同地方也不同,纽约就少用私家车,日常用地铁。洛山矶因为城市设计给汽车利益集团左右,必须有车,但是以开环保车为时尚和先锋。
