Fortunately we are slowly making progress towards a more renewable future. There is definitely a lot of promise in solar, but I would not discount geothermal as a widespread solution. People tend to think about geothermal in the traditional sense of volcanism, but shallow geothermal heat exchange systems can be installed practically anywhere and can greatly reduce heating and cooling expenses. I'll be doing another article on this in the future!

I have never heard of HOMER, but it appears to be fairly powerful (though also proprietary and a little expensive). It is good to know what else is out there in terms of software. I appreciate your comments and support!
