Amplifying our voice

We use a lot of critical and contaminating energy sources to get HOT WATER every day, such as gas or oil. But there is a better option: SOLAR ENERGY


Energy from the sun is FREE and UNLIMITED,
and it doesn’t have any harmful emissions.

La ENERGIA SOLAR es gratis e ilimitada, y no causa emisiones nocivas.

The technology to harness SOLAR ENERGY for heating water already exists and can easily replace less green ways of heating water.

However, awareness of this option is very low, and information about it can be confusing and overwhelming.

Pero el nivel de conscientización es muy bajo y la información al respecto puede ser confusa y abrumante.

We want to change that.
