    Monoculture vs. Polyculture Farming Methods

    Sunday, August 31st, 2008

    Sustainability has become a buzzword- it’s used in reference to energy policy, abiotic natural resources, and cultural practices. It’s also being used in reference to agricultural practices. Though we’ve improved on crop yields through modern farming methods, there are still ways in which we can increase our efficiencies while simultaneously providing a place for nature […]

    A First Step Towards the Hydrogen Economy ?

    Monday, June 30th, 2008

    Recent news has highlighted the opening of the first commercial hydrogen fueling station in California. For people who lease hydrogen fuel cell vehicles (the most common user) or some kind of hydrogen combusion engine, they now have one public place in the state of California where they can refuel their vehicles. A few others already […]

    Deep Water Offshore Wind Energy

    Monday, June 9th, 2008

    Drilling for Oil is not the only Potential Energy Producing Activity Offshore
    While “green” or renewable energy technologies are often seen as the rival against traditional fossil fuel technologies in some kind of epic battle, they can actually sometimes enhance and support each other. Recent news from wind power companies suggests that they may be able […]

    Development and Official Regulation

    Tuesday, June 3rd, 2008

    If we consider development to be the general increase in well being of a population, then we have to recognize that there are times when the increase in one type of measure (real income) is countered by the negative action of another type of measure (disease rates). In these cases, government often steps in to […]

    Energy Efficiency: Good News onto Deaf Ears ?

    Tuesday, May 20th, 2008

    Energy efficiency is a wonderful investment both for businesses and consumers often paying far better returns than the stock and bond markets. If so, then why don’t we take advantage of it? Increases in efficiency can reduce energy consumption for the same or increasing amount of output. All the while, pollution is reduced and money […]

    Review - Kill-A-Watt Electricity Usage Monitor

    Friday, May 16th, 2008

    With energy costs increasing faster than inflation and much faster than income in the United States, many have a desire to conserve. But, without information, our conservation may be more expensive than it is worth and hardly as effective as it could have been. The kill-a-watt electricity usage monitor provides a useful way to be […]

    CAFE Standards and Speed Limits, Round 2

    Thursday, May 15th, 2008

    In this earlier article on the new CAFE standards, I found that depending on the assumptions made for the number of future miles driven, restricting the speed limit to 55 miles per hour would be a more cost effective and more energy efficient solution than changing the CAFE standard. That analysis only considered the total […]

    Landfills as an Energy Source

    Tuesday, May 13th, 2008

    As landfills which hold municipal solid waste are closed the emissions from decay of the material in the landfill becomes a pollutant. That pollutant can either contribute to smog and the increase in greenhouse gases, or it can be used as an energy source. A free, environmentally friendly fuel, potentially harmful if released, is not […]

    Defining Sustainable Technology

    Friday, May 9th, 2008

    Sustainable technology is an idea that may produce a new level of real progress around the world. But often today, the term is more of a marketing badge that may or may not prove to be true when put to the test. I have written before about sustainable technology and some of the problems with […]

    Conservation and the Marketplace

    Thursday, May 1st, 2008

    How Conservation and Efficiency Can Sometimes Increase Consumption
    Conservation and efficiency are always good, right? Unfortunately, not always.
    Many of us, myself included, consider ourselves conservationists. We don’t buy or take things that we don’t need (for example, lots of extra paper napkins at the restaurant). We consider the energy efficiency of […]

    A Way Out of the Politics of Climate Change, Part 5

    Tuesday, April 29th, 2008

    Stay Focused on the Big picture
    This is the fifth article in a five part series.
    In this series, we have been outlining a evidence-based, constructive method to address the issue of climate change. While using this method doesn’t eliminate any disputes, it does change them from one of attacking philosophies, which are not easily changed, […]

    A Way Out of the Politics of Climate Change, Part 4

    Friday, April 25th, 2008

    Evaluating Solution Effectiveness and Translating Analysis into Policy
    This is the fourth article in a five part series.
    To date in this series, we’ve looked at objective measures of how to frame a problem, how to determine the causes of that problem, and consider implementing a robust solution to the problem. In the last article, we […]

    Green Production versus Conservation

    Thursday, April 24th, 2008

    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 […]

    A Way Out of the Politics of Climate Change, Part 3

    Wednesday, April 23rd, 2008

    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 […]

    A Way Out of the Politics of Climate Change, Part 2

    Monday, April 21st, 2008

    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 […]

    A Way Out of the Politics of Climate Change, Part 1

    Thursday, April 17th, 2008

    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 […]

    CAFE Vehicle Standards Compared to Speed Limits

    Monday, April 14th, 2008

    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 […]

    Landfills, Mines of the Future ?

    Friday, April 11th, 2008

    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 […]

    Distributed or Centralized Solar Energy: Costs and Benefits

    Tuesday, April 8th, 2008

    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 […]
