That certainly changes the amortization calculation.<br /><br />As we're seeing in the gulf and in some recent mining disasters, the real costs of conventional energy is much higher than just the $/gallon or c/kwh. While it may be "cheap" to buy grid electricity, we pay for that cheapness in other expenses, increasing its real cost. All of these fossil fuel sources have been heavily subsidized in the past and continue to be. And IF we ever have to spend money on Climate Change remediation, that too will be indirect costs we'll all pay which relates to fossil fuel usage but was never factored into the prices were are paying today.<br /><br />And all of the above assumes it's only a cost calculation. What's the cost of a case of childhood asthma? Or how much is a mountaintop in one of the coal states worth? I bet very few of us buy the cheapest medical care or food or transportation or shelter that is available. Usually the cheapest is not the best value.Matthttps://www.blogger.com/profile/06519351120562721747noreply@blogger.comtag:blogger.com,1999:blog-6120586935905234915.post-18721259824977329802010-06-14T06:47:12.523-05:002010-06-14T06:47:12.523-05:00stick to that veggie diet, the wife and i took the...stick to that veggie diet, the wife and i took the plunge about 2 months ago and we are loving it. we are also starting to become friends with all the vendors at our local farm markets. it is also great for your body and the environment. If you are going to continue to eat meat try to find a local source or try and promote local meats to your favorite eateries like the grub shack and the starlight.dylanhttps://www.blogger.com/profile/16329250365920892022noreply@blogger.comtag:blogger.com,1999:blog-6120586935905234915.post-38744562499340349482010-06-13T14:02:02.756-05:002010-06-13T14:02:02.756-05:00Photovoltaics are expensive, but they are a conven...Photovoltaics are expensive, but they are a convenient way to turn the sun's rays into electricity. Sometimes you need electricity, sometimes you don't. Sometimes you just need heat. Take, for example, John's experiments, and other industrial implimentation of concentrating solar energy via dish mounted mirrors. Also, John's solar water heater and ovens are great examples of (nearly) free solar energy, entirely bypassing the need for electricity. <br /><br />On the issue of meat vs. vegatables: humans are omnivores. That is, we eat vegatables as well as meat. A richly varied diet is best. Most of us eat way too much meat, and it would better for us, the animals, and the planet if we ate less of it. Best is a vegatable based diet, including fruits, berries (extremely nutrient & antioxident packed), nuts, and yes many vegatables, supplimented by small portions of meat, not at every meal. Consumption of cerial grains is not healthy for humans, except when they are transformed into beer or single malt Scotch Whiskey.Allen Harehttps://www.blogger.com/profile/00500590136731959920noreply@blogger.comtag:blogger.com,1999:blog-6120586935905234915.post-14171420483588181212010-06-12T19:42:20.673-05:002010-06-12T19:42:20.673-05:00Mike- I realize you were just making an encouragin...Mike- I realize you were just making an encouraging comment. However, not only is photovoltaic equipment expensive, the point made by Don Lancaster, the gentleman whose link I posted, is that no PV cell has yet been made that pays for itself over its lifetime when all subsidies are included in the amortization of its cost. Only remote installations like John's, where grid electricity is not available or is prohibitively expensive actually are competitive with the price of grid electricity. This should be changing in the next few years as new PV technology and manufacturing efficiencies emerge.Nathttps://www.blogger.com/profile/03878726202192589639noreply@blogger.comtag:blogger.com,1999:blog-6120586935905234915.post-26713391752320215632010-06-12T16:15:57.404-05:002010-06-12T16:15:57.404-05:00Glad you are giving the veggie life a try.

Have you asked them to start serving veggie burgers yet? What about the other place you hit on Monday nights.
