New Worldwatch Institute report examines global consumption and installed capacity of hydropower and geothermal energy sources Although the global consumption and installed capacity of hydropower and geothermal technologies have increased steadily since 2003, both types of energy saw slower growth in 2011, according to new research conducted by the Worldwatch Institute for its Vital Signs Online service (www.worldwatch.org).Global installed capacity …

American wind power has blown through an historic milestone: 50 gigawatts of electric generating capacity, according to the American Wind Energy Association (AWEA). Denise Bode, CEO of AWEA, made the announcement at the recent National Clean Energy Summit in Las Vegas. The 50 gigawatts (GW) online means that U.S. wind turbines now power the equivalent of nearly 13 million American …

Carbon Storage – and More A novel process developed by a University professor with help from an IREE grant aims to produce clean, renewable energy while reducing greenhouse gases in the atmosphere. A University of Minnesota earth sciences professor and a postdoctoral fellow in his work group have imagined a new process for generating electricity with a two-for-one climate benefit. …

SolarReserve Reaches Major Construction Milestone in Completing Tower for World’s Largest Molten Salt Solar Tower Plant Nevada project represents leading solar thermal technology worldwide – integrated energy storage provides predictable and zero-emissions electricity day or night to meet peak demands SolarReserve, a U.S. developer of large-scale solar power projects, today announced completion of the 540-foot solar power tower for its …

“GDC Strikes Steam in Menengai,” exalts the cover of this spring’s issue of Steam, the magazine of Kenya’s Geothermal Development Company. A column of steam spurts high into a deep blue sky in the cover photo—the geothermal industry’s equivalent of the black column that spurts from a successful oil well. But steam is even more valuable than oil, at least …

Spain is one of the world’s most advanced renewable energy players. In 2009, renewable energy represented 12.5 per cent of total energy generation in Spain, and this is expected to go up to 20 per cent by 2020.

Darren W Chow asked: There has been an ongoing debate pertaining to the pros and cons of geothermal energy. Before we can begin to discuss the advantages and disadvantages, we need to have a clear understanding of what exactly geothermal energy is. 4,000 miles below the Earth’s surface is incredibly hot. It is thought to be over 7,000 degrees Fahrenheit. …

Loisa Jamora asked: A quick increase in the population of ecological companies has been noticed following the rising product requests of the organic society. Several green businesses assist the environment by making products that lessens our energy demands. Some of these companies offer alternative energy methods like solar energy, wind power and other services by the geothermal industry. Geothermal power …

Michael L Leigh asked: One of the lesser known renewable energy sources geothermal electricity is created by using the heat contained underground by magma. This magma heats rocks and sometimes travel directly through water sources below the surface heating it up. We extract this water and run it through pipes which surround another set of pipes that contains a liquid …

Daniel Lanback asked: Geothermal energy is the energy taken from the heat stored inside the earth. This energy has been stored inside the earth from its very origination and even from the solar energy, which is absorbed by the surface of the earth. Geothermal energy has been widely used today to provide electrical power in countries. Industries have also been …

Robert Eckard asked: When it comes to geothermal energy, Australia may not hold the top spot in the utilization of this renewable energy, but the potential is certainly there. As it has with other renewables, Australia has turned its attention to geothermal energy as a means to reach certain energy generation goals by the end of the year. These goals …

Arunsi Jeremiah asked: The roots of the word geothermal itself traces back to the two Greek words, “geo” and “therme.” Both these words signify “earth” and “heat” respectively thereby describing what this form of energy is all about. In a few words this form of energy is what is emitted as heat from the deep underground section of the globe. …

Richard Chapo asked: Geothermal energy is a platform tapping the inherent energy found within the Earth. Her is an overview of how the process works from a practical perspective. Producing Energy From Geothermal Resources There are several types of energy used in the world that are considered eco-friendly. These energy types include solar, which harnesses the power of the sun, …

Sheldon P asked: The term geothermal came from the Greek words geo and therme, which means earth and heat respectively. Geothermal is from the heat acquired from the hot circulating ground water of the Earth. People have used this particular type of energy for centuries now. One of the most common sources of geothermal energy is hot springs. The ancient …

Abhishek Agarwal asked: With people looking for more and more ways to find renewable energy sources, many don’t realize they are standing on top of one of the greatest energy resources on the planet. The Earth’s core is at an unbearable temperature, hotter than anyone could possibly even fathom. This heat builds up so much pressure in the Earth’s core …

Steve D Evans asked: How does geothermal energy work is a good question, and one which I have often been asked. In this article I must first explain what it is, and then how it can be made to work for man. Geothermal energy is, literally, the heat of the earth. The heat itself derives from radioactive decay beneath the …

Dane Bergen asked: Geothermal Renewable Energy is a harmless one that is made from the heat of the earth. It does not produce any greenhouse gases. Underground water near volcanoes gets heated and even boiled at high temperatures and produce steam. These are found at a depth of 3000m. the water is collected by drilling wells. The steam and hot …

James Bratley asked: Iceland is a well established leader in the geothermal industry, with just under 90% of the country’s housing heated through the use of geothermal energy. So what makes Iceland so efficient concerning the use of geothermal energy? Iceland is right on top of very active geological ground (the Mid-Atlantic ridge) and is home to a high concentration …

R. S. Palacio asked: Perhaps to most Filipinos, geothermal is “alien”, unheard of or maybe just “a not too exciting topic” to delve on. But what if the regular Filipino would know that geothermal is a cheaper form of generating energy in a sense that it does not require the purchase and use of fuel? And that his country is …
