The insulation/underground temp issues.

You're starting from a higher temperature than you would be on the second floor.

Right. I wasn't sure what you meant, thanks.

I suppose if you wanted two story you could build up but I'm not sure what that would do to the whole setup.

More good news.
http://www.bloomberg.com/news/2011-05-26/solar-may-be-cheaper-than-fossil-power-in-five-years-ge-says.html


Ok so this guy is saying the cost would go down to 0.15/kw, right now i saw ads for diy solar kits at $2.35/kw and higher of course if the company installs them. That would be quite a drop, I wonder if it will really drop that far tho. If it does, guess the hydro utility guy will be as lonely as the Maytag repair man. lol

I believe that's upfront cost.

That article got me to wondering so I searched and found this. Take a look at the bottom and you'll see a breakdown of the math.

Based on those numbers and prices to date the cost is actually around .25 cents if I'm not off astronomically lol. Sometimes these articles can be greatly misleading towards either side.
Edit: It would seem a better marketing move to advertise both..The upfront cost and the long term cost.

Well, people seem to be doing 2 storeys underground, i googled and there were tons of hits. Some very interesting and creative designs too.
I like the concept of underground houses a lot but from a resale point of view, a fairly limited market for them imo, people want a conventional looking house, even minimalist doesnt sell very well. So it would be good to build if you planned to live there forever but if you were going to sell in a few years, I wouldnt want to take the risk of not being able to sell it.
Here is a vid on a partially underground 2 storey house with the rest of the house made of rammed earth.

Compared to conventional, no but they do sell and people do want them for various reason. Vacations, frequent getaways, primary homes, secondary longer term homes and so on.

I like the idea of rammed earth..That was a good video. I'm not sure (speaking for my own needs remotely) that I could implement this easily. I have thought of it..my personal plan was to build a doubled walled cabin from trees harvested on my land and then compact dirt between the logs that I dug out while making a cellar.

Still thinking on this and it was a backup plan if the time came to move and I didn't have the right amount of cash to build like I first wanted.

For others and new homes I think Tim's and your idea are good.

I've done signs for 13 years and I'm seeing more and more business open up that have a really green agenda. It's promising.

Of course there is an environmental cost to everything, and I make many of my consumer choices and lifestyle choices based on those costs. You make wild assumptions about how I live... I take public transportation, I wash only full tubs in cold water. I set my thermostat in a way that is energy efficient. I use energy efficient appliances... things like fans and swamp coolers. I try not to use plastics when other materials are available. I do not buy single serving foods... I used cloth diapers when my son was little.

I live in the modern world, I am not a hermit, but that does not mean I can't contemplate how my actions impact the environment. I do not mind that being penciled in when we talk about the costs of doing business... why do you?

lol You are making wild assumptions that i have made wild assumptions about how you live. I simply said that everything has an impact. I never made any judgement about what impact you make, even the most "green" person has an impact. Just as solar panels have an impact, the materials need to be harvested, they need to be processed, they need to eventually be disposed of, all of those processes have an impact. Their cost to the enviroment add to the cost of panels too.

I love minimalist, I love green roofs, I like a lot of alternate construction methods. I am just looking at how a property would sell or rent out using things like that. Green roofs would be more acceptable to people, I think. Yes, there is a small market for minimalist but if you are trying to maximize your profit potential or rent, then going with designs that are more traditional and conventional will attract more buyers/renters. If you are building for yourself and living there long term, then its a different story, no need to be shackled by what the market out there wants.

What I am sceptical about "green" products or businesses is that something that isnt green can be presented as green. Take carbon credits for instance, I mean, is that a scam or what? If something is actually truely green, then great. I will use green construction products where ever i can but I would need to research those products to satisfy myself that they were indeed green. Unfortunately I am one of those stuborn people that needs to dig into things, I need to understand how things are made and all that goes into them and to know that what is claimed is true.

When I make claims (such as one way of doing things destroys the environment as much as another way of doing things) I try to have sources for what I am saying... otherwise I would think that people might assume I am talking out my ass.

Where did you get that from??? I never said that one way destroys the enviroment just as much as another, I simply said everything has an impact. Dont go putting words in my mouth.

From the article:  "But solar panel prices are on the decline, and if houses and buildings are more effectively insulated, initial investments would be paid back in eight years or so, instead of 15 to 20 years currently, Mitsubishi Research's Komiyama said."

Translation:  Solar takes 15-20 years to pay back its initial cost.  Effective insulation alone, which should cost next to nothing compared to solar, will save just as much money.


That is true today but we know that the more we produce something and the more people compete to sell a product the cheaper and more efficient that product becomes. People will innovate if the economic incentive is there and Japan is creating that economic incentive.

Absolutely.

Here, there is a scheme where the power companies purchase the excess solar power created by domestic solar panels when the household is not using the electricity generated. Electricity is traded back and forth between consumers and power companies. When the house is using more energy than it consumes it buys it off the grid, when the house is creating more energy than it consumes, it sells it to the grid.

Because of the abundance of sun here, some householders have negative energy bills ie they make a profit on their energy trades over a year.

Turning houses into mini-power stations is so sensible. It reduces overall demand on the grid immediately. Supply automatically expands to meet demand as each new dwelling is constructed, reducing overall demand and the need for new (and very expensive) power stations. The need for expensive imported fossil fuel is reduced. CO2 emissions and pollution are reduced.

It increases energy awareness and thrift in consumers. Best of all it decimates domestic power bills. Everyone comes out ahead. Making solar panels compulsory in new houses, and conversion costs tax-deductible in older dwellings is urgently needed everywhere.

Of course, as I said earlier, people will learn more about solar and electric vehicles, and other ways of doing things when there is a reason for them to, like when gas is $10/gal or whatever. People arent there yet. And really, the govt isnt doing much to encourage them to.

You're right of course for the majority but the fire is catching. People don't need the government but it would make things easier because in a sense..it would be people helping each other..I used to think that if enough people wanted a certain thing that the government would listen, they'd have to. Not so much. We'll have to do it ourselves if we want any real change to happen.



Its like any trend, there is a trickle from the early adopters and then eventually growing into the bulge of interest from the majority. No they dont need the govt, they need an incentive of some sort and for many its self-interest, as in forced to due to cost. And given that big oil has so many politicians in their pocket and push their agenda, of course whatever the govt does will be minimal (as now) and they only do that so they can get good PR sound bites and votes.

I do like solar but for me to do that, it would need to make financial sense for me. Maybe I will this year if the numbers actually do work for me and everything else lines up, I cant say just yet tho. The do-gooder part would be icing on the cake and certainly not the main motivation. I am being honest about it, since I cant do it if I cant afford to, most people cant either.

Renewable energy policy in this country has been plagued with red tape since Carter, it hasn't helped. Clinton Gores solar energy initiative made good sense, the "Million Rooftops"program, which was a one time Keynesian stimulus, that simply required all Federal building to install PV capacity.

When manufacturing increases, prices fall, it's called economies of scale - Siemans for example has a PV fab plant, but they only run it Three months out of the year - if demand were such that they could run it year round, prices would fall - starting up and shutting down drives up their costs.

A one time consumption stimulus would drop prices down enough to make it attractive, it basically turns the government into the "early adopter".

And really, to start with, you only need enough PV capacity to run your AC when the sun is shining, and you can phase in more capacity as need and your budget allow.

Half the electrical consumption in the US is domestic, if aggregate demand falls due to PV (or any micropower) from domestic supplementation, prices from coal plants fall, which cuts manufacturing costs for industry, jobs are created manufacturing and installing PV systems, and there is a huge global export market for all this - only a handful of countries have coal, or even significant hydroelectric potential, but they all need power, and when they get power, they'll want stuff that runs on electricity.

Anyway, Bush killed the Million Rooftops program, along with the automobile efficiency program, Freedom car or whatever it was, which was starting to show promise, and made noises about hydrogen, but nothing got funded.

A new program has been proposed, the Ten Million Rooftops program, but it's a different program, tax incentives, etc., not sure of all the details, other than there are details.[8|]

If it works, it could provide the consumption stimulus needed to kick in economies of scale, lets hope - could be the thing we need to kick the economy back into gear.

Typically, when alternative energy is debated, critics can be counted on to ignore the potential cost reductions due to economies of scale, which in the case of PV, are certain to be considerable - it isn't substantially different than manufacturing IC chips, but with much looser quality controls.

Nukes are being pushed hard as a pancea, because they need taxpayers to pay for decommissioning Nuclear plants since the utilities didn't save the money they were supposed to to do it themselves, and nukes are pretty much subsidized from start to finish anyway. Energy traders prefer nukes, because supply is easy to control, and that allows for optimal pricing, much like the oil supply is micromanaged, with a distributed grid, it becomes much harder to micromanage supply and create artificial shortages.

Nonsense. It got axed to pay for Reagan's tax cuts.

Bush II did the same thing again.

List of Clinton-Gore initiatives.

True, but it was a bit of a clunker to begin with, priming the pump with a one time demand stimulus makes more sense, and 2000 would have been an excellent time to do it, chip fabs everywhere were idling and raw materials were stockpiled.

FreedomCAR was a Bush initiative, my bad, the Clinton Gore program was the PNGV, or Partnership for New Generation Vehicles.

Insulation doesn't create power or energy so I would do both.
