The Potential for Geologic Hydrogen for Next-Generation Energy
Hydrogen, you may recall from your school days, is a gas. It is considered the cleanest fuel, because burning it only produces heat and pure water. A previously overlooked, potential geologic source of energy could increase the renewability and lower the carbon footprint of the U.S. energy portfolio: natural hydrogen.

Shutting Down Nuclear Power Could Increase Air Pollution
Nearly 20 percent of today’s electricity in the United States comes from nuclear power. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

From High to Low in 15 Years: Coal Continues Its Precipitous Decline
The country’s power generators used more coal in 2007 than ever before — a little over one billion tons. This year, coal use by U.S. electric-power producers would likely not reach 400 million tons. Roughly 40 percent of the country’s current coal-fired capacity is set to close by 2030. “This is not an economic cycle that is simply going to go away,” says an expert. “It is a real phaseout across the industry of the use of coal.”

Kites Aim to Tap Unused High-Altitude Wind Power
There is a growing interest in harvesting what are known as high-altitude winds. At a height of 200 meters (656 feet) and more, winds tend to blow stronger and more steadily than those closer to the ground. High-altitude winds remain a huge untapped source of renewable energy, but a race to the sky is well underway.

If the Price Is Right: Fusion's Future in the U.S. Could Come Down to Dollars and Cents
Fusion energy is often hailed as a limitless source of clean energy, but new research suggests that may only be true if the price is right. The researchers say that the engineering challenges of fusion energy are only part of the problem — the other part lies in economics.

Tidal Stream Power Can Significantly Enhance Energy Security
A new study reveals the potential of tidal resources to make a marked difference on a community’s clean energy ambitions. Using tidal technologies as part of a renewable energy mix can also reduce the space required for power-generating facilities, both on land and at sea, by around 33% and significantly reduce their visual impact since much of their operation is below the sea’s surface.

Interest in Geothermal Energy is Growing
These days, some 400 power plants in 30 countries generate electricity using steam generated beneath the earth’s surface, producing a total capacity of 16 gigawatts (GW). Despite its advantages, geothermal energy has seen limited use compared to fossil fuels, but recent energy shocks have increased interest in this energy source.

The long view
Using Liquid Air for Grid-Scale Energy Storage
New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.
Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
