In honor of Earth Day on 4/22 (a little late, I know), let's consider the relationship between “green” production and conservation.
Our question is does conservation or “green” production result a greater positive impact regarding our use of resources. I am going to take the case of paper, as it is relatively simple product to manufacture, is a major waste product, and can be easily recycled.
As of 2000, paper consumption in the United States was approximately 324 kg per person. Americans recycle approxmately 38% of that total, and of the remainder that is thrown away, it makes up nearly 40% of the municipal waste stream eventually being incenerated or deposited in a landfill. Recycling has been growing slowly, however, only growing from 20% in 1921 to 38% today . Consumption has grown faster increasing more than 1% compounded annually or over 23% since 1990.

Evaluating Likelihood and Addressing Uncertainty when Applying Solutions
This is the third article in a five part series.
In the first two articles in this series we looked at identifying a problem and a functional understanding of that problem and then at determining all the causes of that problem . Now, we are going to consider how to take account of uncertain data regarding future events both in the probability that they may occur and in the degree to which they might occur. People are generally bad at statistics , which makes this part of the risk assessment process counterintuitive at times. However, risk is something we do accept on a daily basis, and so I will try and find some analogies. Again, this series is about taking politics and argumentative posturing out of the decision making process regarding climate change. To be sure we adhere to that premise, I will continue to make my examples totally neutral regarding the data and whether we are talking about a warming or cooling climate; I am discussing the decision making process.

A Root Cause Analysis on the “Failure Mode” of Changing (Increasing or Decreasing) Temperatures.
This is the second article of a five part series.
In the last article I outlined our functional model of the Earth. According to that model to explain why the current temperature of earth is the way it is, we have a primary energy input from the sun, and secondary energy inputs from other astronomical sources and internal energy from the Earth itself. The properties of the Earth that effect the temperature are the reflectivity, the percentage of energy reaching Earth reflected back out into space, and the emissivity, the ease at which the energy Earth contains can be released into space (cooling at night for example). The goal in this series is to address climate change in a real, technocratic, nonpolitical manner to elimate the arguing and posturing, and outline a process whereby people could identify what problem exists and the best most robust solution.

A Risk Assessment Approach to Climate Change Policy
This is the first article of a five part series.
It is difficult to find a more hotly debated public policy issue today than the one about potential regulatory actions related to global climate change. Much of this debate is emotional focused on various groups' attitudes toward government action and personal responsibility, pessimism or optimism related to human interactions with the environment, and other philosophical differences. That being what it is, I think a different approach could show us the way out of that kind of divisive argument and produce positive action in an amount properly proportional to the nature of the threat. So, in a series of 5 articles, I am going to address this issue, not as a politician or a policy advocate, but as an engineer considering options and trying to reduce the risk associated with a particular problem. To maintain the non-partisan nature of this series, I am going to assume that increases or decreases in global temperatures are equally likely, and since, in theory, they have related solutions, it does not diminish the outcome of the analysis.

What is Risk Assessment; how do we already use it; and how do we misuse it?
If our goal is to achieve progress, one of the ways we can determine that progress has been made is by a reduction in the quantity and severity of problems we face. Another way, would be to determine the quantity and magnitude of new capabilities we gain. However, new capabilities often bring new problems of their own, if we are not careful. The discipline of risk assessment and mitigation or control, if we take the time to apply it properly, can address the reduction of our current problems and the mitigation of potential future problems caused by our new capabilities.

What would more effectively reduce pollution from small vehicles?
Recently, there was a significant political argument in the United States about the costs and benefits of increasing the Corporate Average Fuel Economy (CAFE) standards. Increased efficiency, the argument went, would reduce the consumption of fuel, and therefore help restrain fuel prices, also reducing pollution from vehicles causing reductions in greenhouse gasses and even more important things in the immediate term including smog producing substances, which are a major concern in large cities with warm climates like Los Angeles, Houston, Dallas-Ft. Worth, and Atlanta. The counter argument said that the costs would be too high, adding to the prices of vehicles, reducing auto industry revenue, eliminating jobs, and reducing passenger safety.

In Search of The Best Answer, Not a Better Answer
Whenever there is a major man-made disaster or some kind of accident , responsible officials usually convene a team that conducts an investigation. The results of that investigation will usually identify a “root cause” and several “contributing causes”. If it was a plane crash, the team will probably present the root cause as either pilot error or some kind of maintenance error. But, if you really want to find out what caused the problem and how to fix it, look at the “contributing causes”. Those are the keys to not experiencing that event in the future.

So, how long will it be before our trash is more valuable than existing iron mines?
The municipal waste collection system in the United States is very efficient at removing whatever materials we place in our trash bag. So much so, that we normally find it difficult to imagine the scale of the operation, and especially the scale of the mountain of material that is buried in our landfills each year. I wonder how long it will be before the sources of metals in our landfills is more valuable than our sources of metal ore. Read the rest of this entry »

Back in the good old days…
Cultures seem to have their own ideas about what progress truly is and whether it exists at all or is just an illusion. Americans, in general, seem to have faith in progress over time, yet many continue to just as strongly express nostalgia for times past. Others have a more cynical view of progress believing life and history to be more cyclical, while others who have recently experienced opression have no doubt that progress is real and something to strive for.

自由阿马蒂亚森，诺贝尔经济学奖得主，， 发展一个强大的论点，发展和进步可以不被经济产出和消费单独的基础上衡量，个人自由是一个非常重要的和在某些领域占主导地位的变量在决定是否取得已经或将会作出修改，并在界定贫困的真正是什么。
阿马蒂亚森选择来形容，不是作为一个资源匮乏的贫困，但作为一个缺乏自由。 这些自由包括选择在那里居住和工作，与之相关联，自由选择自己的领导人，并决定我们生活的规则，以及其他许多。 这关键的一点是有用的，它并不专注于财富最大化仅作为一个贫困的出路。 The problem with poverty is not lack of money, but that lack of money means that people are not free to make their own way in life. 他们可能被困在性质，苛政怜悯，或经济cripled糟糕的政策。 因此，结论是这些钱不能单独解决真正的问题。 政府改革，经济自由化和个人自由的普遍提高，是真正的结束，我们正在努力争取。 增加收入，是要完成的几个必要步骤之一，而不是本身并结束。阅读其余本条目»

Excuse me, are you going to use all that Sun in one place?
Given present-day concerns about energy independence, pollution control, and energy price stability, solar energy is often touted as one of the (at least partial) solutions to that problem. Solar energy involves making electricity or other useable energy out of light from the Sun. And while humans have been using solar energy on some level since before history, most applications including solar cells ( photovoltaics ) and other efficient conversion systems have only been in use since the late 1940s. As of 2005, the total share of domestically produced electricity from solar energy was very small at 0.065%, or a total of about 19 billion kilowatt-hours , but growing rapidly.

我们知道我们在做什么呢？ 也许正确的问题是，我们知道我们在做什么呢？ What are the true consequences of our actions today and tomorrow and hundreds of years from now? 我们对这些后果负责，我们还是应该永远不会与他们有关吗？
我相信，我们常常接受没有答案，我们可以有。 我们选择了不知道我们的“帮助”对方的方式是否真的到底要帮助。 We have chosen to push the solutions to problems we have today off into the realm of tomorrow. 虽然一些，可能是合理的（我相当肯定，我的电脑将在5年内更快），不是全部。 阅读其余本条目»
