GCHP leverage other renewables
Some people don't consider a GCHP system as "renewable energy". A GCHP system doesn't produce electrons that can be pushed through a wire. What it does do is reduce the need to push electrons down the wire in the first place...and it does it very well. It doesn't matter how the electricity you use is produced, if you use a GCHP system for heating or cooling, it will use less energy than virtually any other HVAC system.
A well designed GCHP system now operates at a COP of 3.5 to 4.5, and an EER of 25 to 40 (COPc of 7.3 to 11.7). If you are purchasing power from a dirty coal generating station, it will have to burn less coal and emit fewer green house gases. In fact, many utilities use their coal plants only to provide peak power...if enough GCHP systems are installed, there is a good chance it may not have to be activated in the first place. If you use wind or solar power, fewer solar panels or windmills will be needed. If you use nuclear power, you will use less of it.
Reducing the need for power in the first place has large implications for utilities and customers. It means:

In my blog I'll be expressing my opinions about what I've the learned about ground coupled heat pump (GCHP) systems over the last 30 years. I've been very fortunate to work with many interesting people who are passionate about this technology...engineers, geologists, mechanical contractors, drillers, excavation contractors...in different parts of the world. I've learned a lot from them and will be using this forum to pass on some of the things I've learned and feel are important. Please feel free to use this information if you feel it's worthwhile...hopefully you can avoid some of the same mistakes I've learned from.
