Good news. Now we need Geothermal and air to air coupled with solar power. The solar system charges the batteries which runs the pumps which extracts the heat from the ground or air to heat the homes or to extract the heat to cool the homes. The excess heat can be used in summer time to heat water with excess power sold back to the grid. Either way all systems are a go and the consumer is the winner. I must say I am more and more confident that we can beat our dependancy on oil.

Here's another suggestion. A common pipe drilled into the ground for say up to four houses which can be used for Geothermal heating and cooling and cost shared by all four houses. Each owner can install solar chargers to charge a single battery system which operates the pumps for the houses. The excess electricity is sold back to the grid and the money used to pay for the system. If solar power isn't sufficient then the grid chages the battery.

I am working on a spreadsheet to do the numbers for KWH and dollars for PV panels costs with payback years. It is setup for Austin Energy bills, but usable by any utility customers. It will be on the cloud. It will let you see energy (and cost by panel maker) needed to cover all usage or just a subset of appliances used.

The word 'median' in the title of this article should be 'medium' or 'middle'. Median is a statistic.
