  • What’s geothermal again?

    Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • Personal Account: Stanford Geothermal Workshop

    AltaRock Energy’s Matt Uddenberg accompanied a group of staff to this year’s Stanford Geothermal Conference, where AltaRock’s Susan Petty and Trenton Cladouhos gave a presentation on the Newberry EGS Demonstration. This was Matt’s first experience with the workshop, so we asked him to ...

  • Lessons from Indonesia: Mobilizing Investment in Geothermal Energy

    Developing countries will need about $531 billion of additional investments in clean energy technologies every year in order to limit global temperature rise to 2°C above pre-industrial levels, thus preventing climate change’s worst impacts. To attract investments on the scale required, developing country governments, with ...

  • Geothermal Power Approaches 12,000 Megawatts Worldwide

    In 2013, world geothermal electricity-generating capacity grew 3 percent to top 11,700 megawatts across 24 countries. Although some other renewable energy technologies are seeing much faster growth—wind power has expanded 21 percent per year since 2008, for example, while solar power has grown at a blistering 53 percent annual rate—this was geothermal’s best year since the ...

  • Industrial Biotechnology - ASTM Organizes New Technical Committee

    With a total population of nearly 7.2 billion people, and a new birth every eight seconds, our modest planet is straining at the seams. Finding ways to maximize the sustainability of the resources that support us all is of critical importance. One such effort falls under the general heading of industrial biotechnology, which is based on a fascinating premise: that ...

  • Building New Industries and Creating New Jobs in a Plan B Economy

    Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

  • Credit Goes To Radhe Industrial Corporation For Introducing Green Project

    We face two problems in our regular life first one is waste management and another one is pollution. Yes waste material is not managed in a way that we can recycle it and give anew form to that. So briquette plant manufacturer present a modern technique that recycle waste and also decrease pollution. In our daily life thousand tons of waste material is discharged but we burnt it which cause ...

  • Physical, chemical, bacteriological and radioisotopic parameters from springs and wells around Jocotitlan volcano, Mexico

    Samples from seven springs and two wells around Jocotitlan volcano (Mexico), mainly used as drinking water supplies, were studied for physical, chemical, bacteriological and radioisotopic parameters. The temperature of the majority of the water was 5°C higher than the average atmospheric temperature of the zone, indicating a geothermal potential. The water type was bicarbonated mixed, related to ...

  • The Italian Job

    Open loop systems abstract groundwater from one or more boreholes. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate well or body of water. The supply and return lines need to be placed far enough apart to ensure thermal recharge of the source. The key issues for open loop systems relate to borehole yields, licensing and, most importantly, ...
