In this show, Tom Rooney of SPG Solar describes how the solar company is growing, saving valuable resources in the process. Rooney, a serial entrepreneur and a true believer in sustainable energies, has extensive experience in the energy industry. SPG Solar has quickly become a leader in the Western United States, with more than 1,200 grid-connected photovoltaic systems and counting. Rooney reveals how solar photovoltaic systems are saving the state of California thousands of tons of carbon emissions and millions of gallons of water, not to mention all the energy saved in generating the power. Rooney describes the “Water Energy Nexus,” the concept of water needed to create energy. Rooney’s goal is to use the least amount of water possible while creating clean, usable solar energy. “One of the reasons I was so excited about coming to run a leading solar company is that in the whole world, there are probably only two technologies that fix both sides of the [energy] equation at the same time, or at least don’t do harm to one while fixing the other,” Rooney says. “One is solar.”
