In recent decades, consumer and commercial technologies have developed so rapidly, so expansively, that those of us who came of age prior to the digital revolution would hardly recognize the world today if we hadn’t experienced it. Those of us old enough to remember the 1990s could never have anticipated how today’s technologies would infiltrate […]
As per the report by the United States Department of Energy (DoE), an average household in the US uses 90 million BTUs of energy per year. Out of this, most energy is wasted due to lack of insulation, air leakages, lights being left on and other such practices. With global warming being a major concern, […]

Geothermal energy taps into and harvests the heat released from below the surface of the earth. It’s a renewable energy that doesn’t contribute to greenhouse gas emissions. Geothermal energy reduces our carbon footprint and doesn’t take up a structural footprint, either. Unlike the endless fields of wind turbines or solar panel arrays, most of the […]
The idea behind controlling waterways through dams isn’t new. The oldest dam in the world, the Kallanai Dam, began operation on the Kaveri River in Tamil Nadu, India in the 2nd century, and it’s still in use today.
