Bill Swann – Liaison – TXSES

I walk and talk the message of going green. It’s easy. Purchase an electric car. I did. Don’t purchase ancient stored solar energy (fossil fuels) but rather purchase recently stored solar energy (wind power) or immediately stored solar energy (photovoltaics). I did! Educate others. I do by leading the monthly solar workshop.
