How To Boil A Frog

Go to the How to Boil A Frog website and click on EROI.

“EROI” equals “Energy Return on Invested.” It means: how much energy one obtains from getting that energy. It’s a very important concept.

In the 1930s, the EROI for oil was around 100 to 1. Today, it’s around 15 to 1 and declining. When it’s down to only 1 to 1, there’s no sense going any further.

But geothermal is a resource available to us here on the Big Island, and one we know will last a very long time. Longer than oil, for sure.

It’s not rocket science!
