I don't know what you're looking for.
Geothermal: Best for hot and warm humid climates, not as good for cold. When used for cooling the heat it generates can go into your water tank or a preheater so you cool your house and heat your domestic hot water at the same time for a 2 for 1 on investment. When used for heating, the cold it generates can't be used so one only gets 1 for 1 so it's best cooling ones house as much as possible not heating. The cheapest is typically an extra deep well with 2 walls, the geothermal and your drinking water is sucked up the middle pipe and geothermal dumps back to the same well but to the outer pipe where it circulates downward (warming or cooling) and gets sucked back up for drinking or geothermal. That isn't allowed in a few states, some don't allow water used in a heating system to dump into water you drink. For heating a gallon of oil (including inefficiencies) produces 40.7kW of heat and previously cost $1.89/gallon when I last ran the numbers (that's a long time ago). With my electric costing $0.21/kW the same 40.7kW of heat costs $8.55 using electric. Since geothermal is 300% efficient, cut that by a third and Geothermal cost $2.85 in the end to produce the same 40.7kW of heat as someone does paying $1.89 for oil. Aka... not good for heating dominated climates, especially with power plants buring coal to deliver it. I have 2 friends that chose geothermal... one wishes they did solar instead and the other won't tell me how much their electric bill is. Today rerunning the numbers with oil costing $3.59/gallon and my electric is $0.23 geothermal wins compared to oil, $3.59 vs. $3.12 for the same 40.7kW but I think it's because electric hasn't jumped yet. Since I live in an environment of 7-8 months of heating and like 7 days of cooling geothermal isn't especially attractive, but that's because I can't use it for its strength. Change it around and put it in a place with 5-8 months of cooling and in humid environments where swamp coolers can't work and it's going to shine like a superstar compared to the other cooling alternatives (window AC, etc.).
Solar, I have more experience. I have 3 panels on my roof I use for domestic hot water, I've had it 3-4 years now. My in-laws have 8 solar panels on their solar house which they built in 1983, our best friends have 40 evacuated solar tubes, and a coworker has 30 evacuated solar tubes. I don't recommend evacuated tube solar for heating/hot water, don't recommend photovoltaic (the kind that makes electricity), I do recommend the flat panel collectors (the 4x8 ones). Let me know if you want to know why. I wish I'd gotten 3 more panels so I could use it for both heating & hot water, because I really hate spending as much time as I do burning wood. I hate bringing wood in, I hate stacking it, I hate clearing paths in snow to it, I hate the ash, I hate the bugs. Most of all, I hate when it's 35-50F outside and sunny and I'm spending an hour bringing in wood getting a fire going, dealing with ash, kindling, knowing had I three more panels I could let it heat my house and not have to deal with wood. My inlaws with the 8 solar panels (central VT) have all the hot water they need and only burn 1/2 cord of wood/year. They don't need to burn even that much they like their house to be 75F+.
I got my system from
http://www.radiantsolar.com/solar_packages_and_pricing.php the one with the 3 panels & tank. Fortunately the controller they sent is capable of heating and their instructions had me using pipe sized for heating & domestic hot water so I could technically add the 3 panels. I figure in the end the system I got cost me around $7,000 (when copper prices were through the roof) and I got about $3,300 back. I originally calculated around $450-$500/year return but with oil jumping it's now around $700/year.
I concluded today for just fuel it would cost...
$55000+ to heat with straight electricity
$2,469/year to heat with oil ($3.59/gallon)
$2,200 with geothermal (I suspect it's going to jump shortly)
$700/year to heat with wood (or probably around $75-$100 if you do it yourself)
$39/year to heat with solar + 1/4th of one of the above (around here in cloudy New England solar can cover about 75% of ones needs retrofitting so 25% is needed for something else)
Wood is probably the cheapest to install up front and can be really cheap if you get & split the wood yourself but the above only accounts for heating. There's some value to the time & effort with wood. Solar costs me -$700/year technically because solar gives free (or mostly free) hot water all year long saving me money. I'd really consider solar, if you have forced hot water solar will heat your house in spring & fall (but you'll probably need to supplement in winter without Radiant floor heating) and get you free hot water all year long, and there's incentives from the government. In New England where I live many of the houses have forced hot water baseboard heating. That doesn't matter much with solar compared to radiant becase here the dead of winter is always cloudy so even if you HAD radiant floor heating you're not going to get much out of it except in Spring & Fall anyway... which should be enough to get the temps baseboards work at.
Makes me really think again about how much I want 3 more panels. It would cost me about $3000 and I'd get $1,100 back. There are worse things one could spend a couple grand on (like wood
