Are Hydropower Dams the Future of Energy?

By Emily Folk @EmilySFolk Growing concerns about fossil fuels—especially their potential contributions to pollution and global warming—have individuals and governments around the globe looking for alternative sources of power. Hydropower is one of the oldest sources of electricity, already responsible for generating around 52 percent of the United States’ renewable electricity generation according to the National Hydropower Association. Hydroelectric dams are seen as some of the best options available. However, there are challenges that hydropower will need to overcome—otherwise, they may prevent the energy source’s widespread adoption. Current state of…

Emerging Battery Tech for Energy Industry

By Emily Folk, @EmilySFolk Advances in battery technology are transforming one of the most promising movements in the modern energy industry: the push toward renewable energy power solutions. Solar, wind, geothermal, and even hydro energy sources have a lot to offer besides near-limitless energy generation. They are clean in the sense that they have little to no impact on the surrounding environment, and they are generally inexpensive to produce under the right conditions. The problem with most renewable energy sources is that they tend to come with a glaring limitation.…

New Solar Energy Storage Works at Night

By Kate S. Most solar energy systems rely on using sunlight as an immediate power source, but can’t function at night or in cloudy weather. So, what if a solar cell could store solar energy and release it for use after the sun goes down? That’s the technology a materials science and engineering team from the University of Texas at Arlington has developed. They have successfully built a new energy cell that can store large-scale solar energy, even when it’s dark. The prototype is an “all-vanadium photo-electrochemical flow cell” that…
