Peter Dockrill for ScienceAlert: Urban environments are often hotter than rural areas due to the way city structures trap and generate excess heat. This phenomenon, called urban heat islands, was first observed in the 1800s, but a new way of gauging it could help us make the most of this untapped source of geothermal energy. Scientists in Germany and Switzerland have developed a means of estimating groundwater temperature hidden under the surface of our cities, based on surface temperatures and the density of buildings as measured by satellites. A range of factors, including population density, vegetation levels, surface sealing, industrial structures, and transport all contribute to why cities are often hotter than the country. But while scientists have long used satellites to measure heat on the surface, the relationship between ground temperatures and underground temperatures has not been fully explored. Cont'd...

Commercial Operation is Expected by Year-End 2017; Project Expects to Generate Average Annual Revenue of Approximately $33 Million
By Pete Danko for KQED News: In just a few short years, solar power has gotten big in California, and now it’s at the top of the renewable energy heap. Data compiled from daily reports by the state’s major grid manager indicate that in 2015, solar became the No. 1 source of renewable energy in California. Not only did solar beat wind power for the first time, but it also topped drought-depleted hydropower, the long-standing leader in California electricity generation outside fossil fuels and nuclear. The California Independent System Operator doesn’t cover the entire state, but it does manage about 80 percent of the California grid, including those portions served by PG&E, Southern California Edison and San Diego Gas & Electric, the state’s three big investor-owned utilities. Every day, CAISO reports on the hourly electrical output from a long list of sources for the electricity used by 30 million Californians, ranging from biogas at the low end of generation to thermal — natural gas, essentially — at the high end.

Roeslein Alternative Energy is paving the way for environmental sustainability with a new waste-to-energy endeavor. ABUTEC was selected as the flare supplier for this project.
Francois De Beaupuy for Bloomberg: Global Bioenergies SA, an unprofitable French maker of sugar-based gasoline, said oil’s recent slump to $35 a barrel is testing the financial viability of its technology even as it plans expansion in the U.S. “The economic case doesn’t stand with oil at $35, except when there’s a tax incentive” as in various European countries and the U.S., Chief Executive Officer Marc Delcourt said in an interview. Without tax breaks, the company would need Brent crude well above $100 a barrel, he said. Shares of Global Bioenergies, listed in Paris since 2011, have dropped more than 50 percent from their peak in May as oil’s collapse raised investor concern that biofuel makers couldn’t compete. Delcourt is counting on the end of European sugar production quotas in 2017 and changes in U.S. eating habits to keep the sweetener’s price low as it eyes additional capacity. Raw-sugar futures are trading at half their price five years ago. Cont'd...

Anmar Frangoul for CNBC: A common sight in the British countryside, bracken -- a type of fern -- is now being hailed as the next big source of biofuel. Based in the south west of England, Brackenburn produces "brackettes" – biomass pellets made from bracken that they shred and compress into briquettes which produce much more heat when burnt than oak. "In our estimation there's 2.5 million acres of bracken in the UK… it's a huge area," Barry Smith, Brackenburn's marketing and sales director, told CNBC in a phone interview. "Left unchecked, bracken encroaches by three percent a year… at the end of the day there's no use for it whatsoever," Smith added. "It's a nuisance and to call it a crop is kind of giving it a status it doesn't deserve." Cont'd...

Turboden expands into the Asian geothermal market: 6 MW started up in Japan and 50 MW to be supplied in the Philippines
An innovative 6 MW geothermal power plant operating commercially in Japan since June 2015. Turboden selected as official technology provider of a 50 MW geothermal Organic Rankine Cycle (ORC) system in the Philippines.
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...
