 Calculation Notes

We know that the US produces 3.639 GW from 64 sites and the global total is 12.7 Gw therefore we assume that there are approx 221 plants around the world. We also know that the biggest Geothermal site "Geyser's Geothermlal Complex California" produces 1205 Mw and Mitshbshi Hitachi's turbine output is a maximum of 110 Mw per turbine therefore the number of turbines is assumed to be 12

If enough businesses act, together we can slow down or help to prevent Global Warming.

Create your Policy

The case for a great return on investment, from water and energy savings is very clear. "Adopt an Investment Policy to Prevent Global Warming".

Real World Examples

We have the know-how to do things differently and help both the environment and the bottom line.

A Summary of Evidence

We estimate that widespread adoption of more climate-friendly policies in industry globally, could have the equivalent impact of taking 529.5 million cars off the roads.
