California Ramping Up Its Reliance on Geothermal

After years of being overshadowed by solar and wind, geothermal is set to become a major player in California's renewable energy. Here is how geothermal is growing in California right now.

Re-Using Waste Heat for Reducing Residential Energy

Simply, waste heat is heat that is produced by a machine or an energy output process, as a byproduct of doing work. According to the laws of thermodynamics, all such processes give off some waste heat.

Kentucky's First Binary Cycle Geothermal Power Plant

Geothermal energy, not to be confused with geothermal heating and cooling, is a clean, renewable, and sustainable form of energy that uses the hydrothermal fluids from the Earth's core to power turbines

A Geothermal Utility Model

Geothermal in a commercial building will displace the cooling tower and heating boilers. We provide thermal energy to the building which gets utilized by either heat pumps or chillers.

How Geothermal Systems Work and Where They Fit in the Energy Industry

Below the earth's surface, there's a source of power with impressive potential - geothermal energy. This source of power revolves around using the natural temperature of the earth to produce power and provide heating and cooling for buildings.

Geo-exchange: Green Potential Muddied by Misconceptions

We cant have confusion hamper uptake of geo-exchange technology. That matters, because the technology has the potential to be a key contributor to decarbonization efforts and offers real benefits to American businesses, households and grid operators.

SD Mines Researchers Explore Hydraulic Fracturing to Expand Geothermal Energy

The process could enhance the use of the earths own heat as a source of clean energy.

How Heating your Home with Renewable Energy Works

Even if you don't totally convert to renewable energy, using it to offset the cost of your heating and cooling can save you a lot of money in the long run.

Geothermal Tax Credits Reinstated

The newly reinstated tax credit is a positive step that further aligns geothermal as a significant energy source for the market. The tax break will drive sales in the industry and encourage people to adopt geothermal systems.

Dandelion Acquires Geo-Connections, the Nation's Leading Geothermal Software as a Service (SaaS) Company

Acquisition will result in technology to push geothermal industry towards critical mass

Striving For Perfection: Flow Energy Partnership Improves Geothermal Energy Production

For efficient Geothermal energy production, water is heated from the earths natural heat in geothermal wells, then is cooled off and sent back into the earth to be reused in the energy-generating process.

Geothermal Leaders to Convene in Washington DC for Showcase

Building on this momentum, the Geothermal Energy Association's (GEA) U.S. and International Geothermal Showcase this March will highlight to Washington DC decision makers how leading geothermal nations are unlocking their geothermal potential.

36 countries launch world alliance for geothermal energy

Thirty-six countries gave the official start Monday to an initiative to promote geothermal energy in developing economies as a cleaner alternative to oil, gas and coal. The Global Geothermal Alliance, launched on the sidelines of the UN climate talks in Le Bourget, aims at a sixfold increase in geothermal electricity production and a tripling of geothermal-derived heating by 2030. At present, geothermal is growing modestly, at three to four percent per year, providing 12 gigawatts of electricity annually. But this is just a fraction of its overall potential of 100 gigawatts, according to the industry. Only 24 out of 90 countries with geothermal potential actually use the resource. The alliance said its members will seek to overcome "political uncertainty" about geothermal and strengthen the industry's skills base. The Global Geothermal Alliance initiative was sketched out in September 2014 at a summit organised by UN Secretary General Ban Ki-moon. Members include countries on thermal "hotspots" in Africa, Southeast Asia and Latin America, ranging from Kenya and Tanzania to Malaysia, the Philippines and Guatemala.   Cont'd...

Researchers want oil and gas drillers to adopt geothermal technology

By Brooks Hays for UPI:  Researchers at the University of North Dakota believe geothermal energy production should be a significant part of America's future energy portfolio. But to get the industry off the ground, proponents are looking to an industry not normally associated with renewable energy -- gas and oil drillers. "Oil- and gas-producing sedimentary basins in Colorado, Illinois, Michigan, and North Dakota contain formation waters of a temperature that is adequate for geothermal power production," researchers wrote in their new study on the subject, published this week in the journal Geosphere. Geothermal energy requires heat, and natural sources of heat lie deep within the ground. Gas and oil drillers have already built the infrastructure to access deep-lying natural resources. Of course, gas and oil drillers want gas and oil, not heat. But in their quest for gas and oil, they get heat nonetheless.  Cont'd...

Balls of DNA Could Fix Geothermal Energy's Biggest Problem

Shara Tonn for  Geothermal Power has the potential to be cheap, reliable, and abundant—running off the heat of the Earth 24 hours a day, seven days a week. That’s especially true thanks to a new generation of home-grown geothermal plants, which don’t run off the steam of natural hot springs and geysers. No need to find those hydrothermal gems; today, geothermal engineers are making their own reservoirs by drilling down into hot rock and pumping in water. The catch? Engineers can’t see what’s happening underground. Drilling wells in just the right spot can be like playing golf blindfolded: Even if someone faces you in the right direction, you could still hit the ball way off the green. But tiny fragments of DNA dropped into the wells could soon help engineers follow the path of water underground, helping them sink their putts every time. In a basic geothermal plant set-up, engineers actually have to drill two types of wells. The first kind, which goes down two or three miles, carries cold water down deep, where it fractures the hot rock and creates new paths for water to move. It’s kind of like fracking, but without the chemicals.  Cont'd...

RBI Solar - Dahlia Has You Covered

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
