It's worth crunching the numbers and considering the value as to how those areas function as quasi-conservation easements & provide habitats, in odd-shaped & small parcels.

Quite literally, yes. The CO2 that cars emit would be absorbed by the plants. All plants do this anyway, and the CO2 that cars generate is no different than any other CO2, so I can't see it having much impact. I think that the sort of pesticides, herbicides and fertilizers used on traditional crops would result in far more contamination than any additional contamination from things like sprayed oil, diesel soot or hydrocarbons from cars with broken emissions control systems. But in any case, even if we grew food crops on highways, most of the grain we grow goes to cattle feed, not human consumption - so you likely wouldn't be eating it anyway.

billvon 2,991 #83 May 5, 2008 >what's your true cost amortizing your power system? Let's see. I have a 30 year mortgage, so let's amortize the system over 30 years. $14,000 (original 1.5kW system) plus $10,000 (additional 1.3kW) is about $800 a year, or $66 a month. But wait! That assumes no increase in resale value. Per the US Home Appraisal Institute, a solar electric system increases home value by $20,000 for each $1,000 in annual reduced operating costs. Since I saved about $1030 a year, that means the value of my home is up $20K. Averaged over 30 years, that's $55 a month. So the "true" cost is $5 + (66-55) or $16 a month. Now, what's the true cost to you of coal power? To calculate that, you have to determine what a year of your life is worth, and calculate how much coal power is reducing that, as well as the damage acid rain is doing to your house, car and property. How much it injures you depends on where you live; in Massachusetts in some areas the average is a six month reduction in lifespan. Quote Share this post Link to post Share on other sites

First order costs are what I was interested in, since they were actual costs, and quantifiable. Potential real estate value is less known - should increase while power costs do, but also decrease as it ages or technology passes it. Does the $24k include any tax rebates (state or fed) - and are those still available? I understand that in its infinite wisdom, Congress has wind and solar credits set to expire next year (while extending oil subsidies long term). With the costs of the power problems to CA in the past decade, it doesn't seem crazy to spend any energy money in the form of residential solar panels.

billvon 2,991 #85 May 5, 2008 >Does the $24k include any tax rebates (state or fed) On the $14K cost I got about a 40% buydown credit from California, so final cost was around $9K. On the $10K I did not get any credit, since I did that myself with Ebay panels. (To qualify for the buydown you have to have a licensed installer, electrical inspection, utility inspection, new-from-the-factory panels etc.) Overall it was actually a little cheaper to go with the Ebay panels, even without the buydown.

I don't believe that any state is primarily a stand alone income generating body. As I alluded to, CA is spending billions on new power generation directly and indirectly, so it may well be most cost effective even in the short run just to subsidize folks like Bill. When I've done the simple division of cost/number of households served, new gas generators don't seem cheap, and they have to be fed to work. Solar credits are definitely effective in the long run, both for advancing the technology to helping meet the state's goals on emissions by 2020.

There are plenty of built-in mechanisms to balance CO2 in our environment, including increased rate of plant growth, carbonate formation etc. We're just overwhelming them.

lawrocket 3 #97 May 13, 2008 Are you thinking that the clathrate gun has just been cocked? I'm not so worried about the methane - it's trend is up 5 ppb to about 1784 in the last 4 years. CO2, though, just keeps growing and growing!

Right now methane is rising at a rate such that it's only adding about 10% to the warming over the next 20 years, compared to CO2. But if clathrates/permafrost really does start outgassing, then we end up with a very rapid positive feedback cycle where warming releases methane, methane warms the air etc etc. Quote Share this post Link to post Share on other sites

I wouldn't be so sure about that. How much lead do you think is in the soil adjacent to highways, from decades of using leaded fuels? As for pesticides/herbicides, these are largely surface contaminants of food. Nothing that a good wash with soap and hot water won't take care of. I've never seen any evidence that they are absorbed into the food in any sort of levels that I would be concerned with. Fertilizers, unlike pesticides and herbicides are not toxic per se (a little bit of nitrogen, potassium and phosphate isn't going to hurt you), but they have a huge environmental impact. When they leech into waterways they can cause algal blooms which lead to eutrophication (http://en.wikipedia.org/wiki/Eutrophication). And the production of ammonia for fertilizers (through the Haber process) uses HUGE amounts of energy, which ultimately comes from fossil fuels. This is in fact the largest fossil fuel input into conventionally grown food, not harvesting, transportation, processing, etc. QuoteBut in any case, even if we grew food crops on highways, most of the grain we grow goes to cattle feed, not human consumption - so you likely wouldn't be eating it anyway. CO2, agreed. Heavy metals and other pollutants? Not so much.
