You can't open the paper or surf the web without learning about a company that has just installed a new solar photovoltaic (PV) project. However, solar PV is only one of several ways you can use free energy from the sun. This article, written for the SBP's December 2011 e-newsletter by Ruben Lopez, is a primer on solar hot water systems, also known as thermal systems.

There is confusion out there about two terms that have become intertwined: the so-called "Green Movement" (interchangable with "Sustainable Movement") and "Environmental" (or "Environmental Responsibility"). This brief article sets out to make a distinction between the two and help readers differentiate between their meanings.

December's e-newsletter (Vol. 1, Winter) contains articles on understanding the difference between 'environmental' and 'green' and how solar hot water can work for you. Auntie Green, concerned by the ongoing drought in this region, seeks an answer to reducing water usage to make this valuable resource last. This issue also features G-Oil as the SBP client in our recurring segment, Clients Corner.

This quarter finds Auntie Green confused over anticipated Texas water usage. It begins with Auntie's concern over "just how long is this drought going to last?!" Our initial answer involving acre-feet of water doesn't really help much. As our dear Auntie's blood pressure starts to rise, we have to quickly explain some leading edge developments - which may reduce water use - to calm her down.
