2050 Projected Alternative Energy Supply and Demand Study

[php function=7]April 9, 2010 Summary The purpose of this study is to provide a first-pass approximation of world energy needs in 2050, and the ability of alternative energy to meet those needs. We make this approximation according to a specified methodology: We calculate the primary energy consumption per capita of the United States for 2008, … Read more

Why Solar and Wind Energy is Inappropriate for Utility Power Backbone Grid Generation

Reprinted by permission from “The High Cost of Free Power,” Laurence Hecht, et al. Every time someone mentions wind or solar power as the answer to our energy needs (for baseline or power grid generation,) the image that should form in your mind is that of 1 billion or more dying and starving children. If … Read more

A Comparison of Energy Densities of Prevalent Energy Sources in Units of Joules Per Cubic Meter

Bradley E. Layton, Ph.D Assistant Professor, Energy Technology Program Director, Drexel University Abstract Typically, the energy densities of solids or liquids such as coal and oil are measured in dimensions of energy per unit volume or energy per unit mass, whereas solar, wind, and hydroelectric sources are rated in dimensions of power per unit area. … Read more

Is Sustainable Energy Even Possible at the Global level?

David J. Pristash January 2012 Revised February 2013 Republished with permission ABSTRACT The purpose of this paper is to place into useful perspective the development of sustainable energy at the global scale. Global scale energy requires the ability to generate power of 3,500 Quads or 3.7 X 1021 Joules, economically; as this is the amount … Read more

Sustainable Energy — without the hot air

Download the full free E-book here. A ten-page synopsis We have an addiction to fossil fuels, and it’s not sustainable. The developed world gets 80% of its energy from fossil fuels; Britain, 90%. And this is unsustainable for three reasons. First, easily-accessible fossil fuels will at some point run out, so we’ll eventually have to … Read more

The Myth Of Ocean Acidification By Carbon Dioxide

Arizona Daily Independent BY: JONATHAN DUHAMEL JANUARY 28, 2014 We often read in the media that increasing carbon dioxide in the atmosphere is making the oceans too acidic, and dissolving or otherwise harming carbonate-shelled marine fauna. These writers or reporters seem ignorant of the fact that these marine fauna evolved when the atmospheric CO2 concentration … Read more

What Makes a Smart Meter Smart?

The Transformation of Ratepayers into Customers Tom D. Tamarkin May 18, 2012 Abstract: The early electrification of communities throughout the world in the 20th century was based on public policy which largely ignored the utility customer. The United States of America, as an example, built a nationwide transmission and distribution system which delivered electrical power … Read more
