World’s first geothermal-solar plant opens in Nevada

The Stillwater geothermal plant in Nevada has added a solar array and now provides 59 MW of clean, steady power. Geothermal produces power 24/7 while the solar provides extra power during the day when it is most needed.

Low temperature geothermal could be a game-changer

Traditional geothermal technology requires 360+ degrees Fahrenheit sources that are difficult to find, less abundant, and therefore costly to discover and develop. Low-temperature geothermal technology makes it possible to access resources as low as 165°F. According to the SMU Geothermal Laboratory, this innovative technology is a “game-changer” and widely opens doors for the geothermal industry.

Geothermal expansion at The Geysers, already biggest in the world

The Geysers in northern California is planning a $700 million expansion, to add 98 new MW of geothermal power.

The Geysers is [already] the single largest geothermal operation in the world, producing up to 725 megawatts of green energy around the clock — enough electricity to power the entire city of San Francisco.

Geothermal powers 20% of Reno during the day

At night, geothermal production meets 50% of Reno’s needs. Geothermal is reliable and steady, producing power 24/7.

Pumps pull 6,000 gallons of water a minute out of reservoirs 3,000 feet below the surface. The water, naturally heated by geologic forces to approximately 300 degrees Fahrenheit (150 C), boils a chemical refrigerant contained in sealed [...]

California’s installed renewable energy numbers may surprise you

If asked what type of renewable energy is most prevalent in California, most would choose solar or wind, but in reality, those two forms of renewable energy aren’t even close. Instead, the current California champion for renewable energy is geothermal, followed by small hydro. Say what?

As an example, on Wednesday May 4, 2011, [...]

Geothermal plants near the Salton Sea

Several geothermal plants on the southeastern shore of the California’s inland and saline Salton Sea have reliably been producing power for 30 years. A new 50 MW plant should be online by next February.

Experts blame German quakes on deep geothermal power

A quake that caused cracks in buildings in August 2009 and six more perceptible temblors the next month probably came from an increase in hot-water pressure in the pores of the rock after water was forced down a bore to keep the supply of hot water going.

Geothermal can produce power on a [...]

Geothermal energy. KQED interview

CalEnergy Vice President Mark Gran introduces the company’s 340 megawatt geothermal plant on the southern shore of the Salton Sea. The plant produces enough energy to power around 300,000 homes. The Imperial Valley has the potential to produce a stunning 2300 megawatts of this renewable resource. Thats enough energy to power more than 2 [...]

DOE introduces Big Oil to new energy source: waste heat geothermal

Every barrel of oil extracted in the US also produces ten barrels of hot fluids in addition to the oil. Why not use that potential energy in the waste heat?

The Department of Energy plans a demo to show oil companies how to capture waste heat from drilling fluids and create electricity on-site, thus [...]

Maui could get virtually all its power from renewable sources by 2020

Wind turbines on Maui, Dec. 2006.

Wind, solar, hydro, biogas from waste, and their as-yet-untapped geothermal resources are the reasons why.

But the group’s top recommendation was to look for more ways to conserve energy.

“A megawatt saved is always going to be cheaper than a megawatt installed,” he said.

Absolutely.
