Lithium-ion (Li-ion) is the most commonly talked about battery storage technology on the market these days, and for good reason. Li-ion batteries have a high energy density, and they are the preferred option when mobility is a concern, such as for cell phones, laptop computers, and electric vehicles. But there are different energy storage technologies […]

As leaders around the world take steps to decarbonize energy supplies, many people have focused their attention specifically on wind and solar power. What they may fail to recognize is that nuclear power provides more electricity in the U.S. than all other carbon-free sources combined. This is true in some other countries, such as France, […]

A lot of energy is consumed by buildings. In fact, the Alliance to Save Energy, a nonprofit energy efficiency advocacy group, says buildings account for about 40% of all U.S. energy consumption and a similar proportion of greenhouse gas emissions. Some estimates suggest about 45% of the energy used in commercial buildings is consumed by […]

Most people are aware that wireless charging technology is available today for small electronic devices, such as cell phones and watches, but when it comes to larger-scale power systems, the concept of wireless transmission of electricity probably seems like science fiction. The truth, however, is that systems have been developed and are being tested that […]

The technology used in modern hydrogen fuel cells is not new. In fact, NASA used fuel cells for its manned space missions in the 1960s. But fuel cells have not really “taken off” (pardon the pun) in earthly applications since that time. Some industry insiders believe that will change very soon. “We’ve been sort of […]

Florida is known as “The Sunshine State,” so it’s no surprise that solar energy is growing rampantly across the state. Among the utilities adding solar resources to their energy mixes is Florida Power and Light Co. (FPL). FPL claims to be the largest energy company in the U.S. as measured by retail electricity produced and […]

In late 2013, Mexico embarked on a path to transform its energy markets. Then-President Enrique Peña-Nieto oversaw constitutional reforms that ended state-run monopolies, and opened Mexico’s power market to competition and investment from foreign and private companies. By most accounts, the policies were highly effective in spurring investments in renewable energy and efficient natural gas-fired […]

When evaluating resource adequacy requirements, many power companies and grid operators have used a methodology that originated more than 70 years ago. This probabilistic reliability approach has generally performed adequately through the years. It has generally evaluated loss-of-load events occurring at frequencies of one-day-in-10-years (1-in-10) to be acceptable in terms of system reliability. However, it’s […]

Lithium-ion has become the dominant battery technology used in energy storage applications around the world, but that doesn’t mean it’s the only, or even the best, technology available. Many companies are working on different battery chemistries that could provide safer, longer-lasting, and ultimately more cost-effective options. One alternative that has gotten little exposure until now […]

Power systems around the world are changing. Renewable energy, mainly in the form of wind and solar generation, is being added everywhere, while more traditional forms of power, such as coal-fired and nuclear generation, are being retired from the grid. Meanwhile, natural gas-fired generation has taken the lead role in facilitating the transition by providing […]
