		<description>@ George - you are correct, I mistakenly used the wrong word in my comment. It should have been misanthropy, not misogyny.



After deeper consideration, perhaps it was not quite as much of an error as one might imagine.



After all, Florence, who suffers the most in low energy economies? Who spends their days gathering wood for cooking or water for drinking? Who does not have access to indoor lighting, refrigeration, or labor saving devices? Who has to watch their children suffer from poor nutrition, lack of education and lack of clean drinking water?



Though all people in those economies suffer, I do not think I would be inaccurate to say that women suffer more than the men.</description>

		<description>ummmmmm.



I&#039;m a bit confused by the last guys comment. Well, at least what I read of it. He claims that you are suffering from &lt;a href=&quot;http://en.wikipedia.org/wiki/Misogyny&quot; rel=&quot;nofollow&quot;&gt;misogyny&lt;/a&gt;, but I don&#039;t see how &quot;Hatred Towards Women&quot; has anything to do with an article about &quot;Investing in Clean Energy&quot;



Can somebody please explain?</description>

		<description>Joshua:



In contrast to your misogyny, I happen to enjoy the presence of my fellow human beings. Unlike Bernard Marx in Brave New World, I also recognize that without them, the world would be a much more hostile place, one where I would struggle to simply survive. That is not because I am a weakling, but because I have a pretty fair understanding of human history and because I have tested my limits on a few primitive trips.



I love to drive and have probably put between one and two million miles on my various automobiles over the years. My current car, a 2002 VW Jetta TDI has more than 152,000 miles on the odometer. I do not want the people who are on earth today to be the last ones to know what it is like to be able to travel freely on a timetable that is unrestrained by monopoly transportation providers. (Before automobiles, any trip longer than a few miles required the assistance of the railroads.)



I love the fact that I can sit in my home office and write comments and articles to share my thoughts with the world. I have a deep appreciation of the contributions of millions of people who have developed electricity, built a reasonably well maintained grid to distribute it, developed software, fiber optics, cables modems, semi-conductors, and countless other devices and components that make it possible for me to do that.



Like you, however, I am concerned about the impact that sometimes careless humans have on both the planet and on their fellow human beings. I can think of countless examples of wonderful, caring humans that I have met and worked with over my nearly 50 years on the planet, but I can also point to inconsiderate, greedy people who have the ability to make life miserable for most of those around them.



It is a shame that people do not think about energy supplies very much until the prices increase to the point of real pain for most of us and very real pleasure for a tiny group of exceedingly greedy people. However, without the work of many, we would be in real trouble since primitive wood burning is a dangerous, destructive energy source. I do not know about you, but without technology, starting and maintaining a fire - assuming I did not run out of broken limbs - is about the limit of what I could do to keep myself warm in order to survive.



When it comes to clean heat that can be turned into power, the very best - and cheapest - source that I know is heavy metal that can be fissioned. Commercial nuclear fuel costs utilities about 50 cents per million BTU, coal costs about $3-6 per million BTU depending on distance from the mine, natural gas (methane) costs about $5-22 per million BTU depending on location, and oil based fuels cost between $19-40 per million BTU depending on location and grade. All of those BTUs are roughly equivalent for certain kinds of heat engines that can be used to produce motive power for large vehicles and electricity.



Of course, anyone who knows me will also know that I constantly point out that nuclear fission is clean enough to run inside a sealed submarine.



Our mantra as submariners was &quot;Remain Undetected&quot;. I think that is a pretty fair approximation of the environmentally concerned backpacker&#039;s motto of &quot;Leave No Trace.&quot;</description>

<p>I love the fact that I can sit in my home office and write comments and articles to share my thoughts with the world. I have a deep appreciation of the contributions of millions of people who have developed electricity, built a reasonably well maintained grid to distribute it, developed software, fiber optics, cables modems, semi-conductors, and countless other devices and components that make it possible for me to do that.</p>
<p>Like you, however, I am concerned about the impact that sometimes careless humans have on both the planet and on their fellow human beings. I can think of countless examples of wonderful, caring humans that I have met and worked with over my nearly 50 years on the planet, but I can also point to inconsiderate, greedy people who have the ability to make life miserable for most of those around them.</p>
<p>It is a shame that people do not think about energy supplies very much until the prices increase to the point of real pain for most of us and very real pleasure for a tiny group of exceedingly greedy people. However, without the work of many, we would be in real trouble since primitive wood burning is a dangerous, destructive energy source. I do not know about you, but without technology, starting and maintaining a fire &#8211; assuming I did not run out of broken limbs &#8211; is about the limit of what I could do to keep myself warm in order to survive.</p>
<p>When it comes to clean heat that can be turned into power, the very best &#8211; and cheapest &#8211; source that I know is heavy metal that can be fissioned. Commercial nuclear fuel costs utilities about 50 cents per million BTU, coal costs about $3-6 per million BTU depending on distance from the mine, natural gas (methane) costs about $5-22 per million BTU depending on location, and oil based fuels cost between $19-40 per million BTU depending on location and grade. All of those BTUs are roughly equivalent for certain kinds of heat engines that can be used to produce motive power for large vehicles and electricity.</p>
<p>Of course, anyone who knows me will also know that I constantly point out that nuclear fission is clean enough to run inside a sealed submarine.</p>
<p>Our mantra as submariners was &#8220;Remain Undetected&#8221;. I think that is a pretty fair approximation of the environmentally concerned backpacker&#8217;s motto of &#8220;Leave No Trace.&#8221;</p>
