    California Zero Net Energy Program: Part 2

    The California Zero Net Energy program discussed in the previous post will have a significant impact on new construction. The average residential electric power usage in the State of California is 6,741 kWh per year (U.S. Energy Information Administration) or 18.5 kWh per day on average. Presumably a residential home will generate electric power using […]

    California Zero Net Energy Program

    I recently read an article about the California Zero Net Energy program whose stated goal is that all new residential construction in California will be zero net energy by 2020. All new commercial construction will be zero net energy by 2030. Zero Net Energy (ZNE) is defined to be that the building will produce as […]

    Free Electric Power

    The New York Times published an article recently on how TXU Energy (Dallas/ Fort Worth, Texas) is offering their customers free electricity during certain times of the day. A little background may be helpful. There are three electrical grids that cover the mainland United States, essentially East coast, West coast and Texas. Several years ago, […]

    Electric Power Generation Business Model – Part 1

    In the 1990’s the trend was to break-up the electric utility monopolies into separate Generation, Transmission and Distribution businesses. The intent was to open up the electric power generation side of the business to more market oriented competition with the hope of lowering prices for electricity at the wholesale and retail level Two trends have […]

    Globalization and Free Trade Agreements

    I recently read an article in the Wall Street Journal that analyzed capital investments by multi-national car manufacturers in North America. These multi-billion dollar investments in car manufacturing facilities both completed and planned covered the period from 2005 through 2020. The time line of investments completed and planned during this period shows four (4) in […]

    Solar Arrays as Distributed Power Generators

    I have noticed several trends in the electric power market which I find very intriguing. The first is the development of distributed power generation. I am not referring to the growth of the large merchant power generators, but the growth of the individual residential power generators. My sister and brother-in-law live in Hawaii. They installed […]

    Rapid Prototyping using 3-D Printers

    I have read several articles recently on three dimensional printing. The concept is to “print” plastic or metal, layer by layer forming three dimensional objects. Each layer is approximately 20 to 30 microns (0.02 to 0.03mm) thick. Coordinated by a three dimensional computer automated design (CAD) software, the designed object is sliced into thin layers, […]

    Mathematics of Globalization

    I recently read an article in The New York Times – “Exchange Rate Hurts Toyota, giving Rivals a Chance to Leapfrog It” (September3, 2010). The gist of the article is that because of the strengthening Yen against the US Dollar and the fact that Toyota imports 35% of the autos it sells in the US, […]

    A More Complete Globalization Analysis

    Any discussion of globalization tends to be sharply focused on the lost of traditional manufacturing jobs. The conversation begins with the fact that this manufacturing facility closed and the production was moved to “you name the low wage country“. I read an article which quoted an analysis performed by the Personal Computing Industry Center at […]
