As we enter the final month of the presidential election campaign, the political rhetoric remains heated. Among the many issues to be debated, renewable energies and the federal policies that support them will no doubt feature prominently.
The headquarters for Burbank (Calif.) Water and Power (BWP) has slowly transformed into a green campus. The effort involved repurposing some of the utility’s decaying old facilities, which, in some cases, were more than 100 years old.
Research into photovoltaic (PV) technology, like all renewables, is always striving for greater efficiencies and lower production costs. That quest often creates seemingly unimaginable possibilities. For example, consider solar glass with a view.
Efficiency and conservation have become well-established elements of the green power movement, and, in that regard, smart meters have become one of the primary tools to help consumers and utilities do their part.
In the years that renewable power has been fighting for market competitiveness, overcoming the high capital costs compared to conventional energy sources has always been the big challenge. Now, for at least one form of renewable energy, it appears that challenge may have been met.
The Department of Energy (DOE) released a renewable-energy resource assessment detailing the potential to develop electric power generation at existing U.S. dams that aren’t currently equipped to produce power.
Despite the rhetoric, popular sentiment and public policies favoring green power, it may be surprising to realize that alternative-energy industries are still the underdog in the transformation of how we generate and consume power.
A few months ago, I was driving home from the Los Angeles area and suddenly found myself surrounded by thousands of wind turbines lining both sides of Interstate 10. Even though I have made this trip many times, I am still in awe at the scale of it all.
Energy efficiency is often the ugly stepsister in alternative-energy conversations because quantifying its potential effect is difficult; how do we determine the real value of all those avoided kilowatt-hours?
I started this series of articles after a friend asked some questions about overcurrent protection for the direct current (DC) output of photovoltaic (PV) modules, the DC output of combiner boxes, the location of disconnects for both the DC side and the alternating current (AC) side of the inverter,
Renewable power has the potential to transform our energy consumption, but like most innovations, it has a downside. One of the biggest stumbling blocks to a renewable-powered society is the intermittent nature of its generation.
