We are noticing a major shift in the way today's homeowners shop for solar. The era of the solar "hard sell" is coming to an end - solar shoppers are educating themselves about all their options beforehand, and placing more value in the ability to compare multiple quotes before they commit.
Overcoming the First Cost Barrier to Ground Source Heat Pump Technology: The Utility Ground Loop Service Provider Concept
Several utility CEO's and PSC/PUC regulators have all acknowledged the importance of GHP technology in the overall landscape of the energy industry.
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...
Jim Sharkey for SpaceFlight Insider: NASA’s Juno mission has broken the record for distance traveled by a solar-powered spacecraft. Juno reached this milestone at 11 a.m. PST (2 p.m. EST) on Wednesday, Jan. 13, when the spacecraft was approximately 493 million miles (793 million kilometers) from the Sun. The record was previously held by the European Space Agency’s (ESA) Rosetta spacecraft, whose orbit peaked at the 492 million-mile (792-million kilometer) mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko. “Juno is all about pushing the edge of technology to help us learn about our origins,” said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. “We use every known technique to see through Jupiter’s clouds and reveal the secrets Jupiter holds of our solar system’s early history. It just seems right that the sun is helping us learn about the origin of Jupiter and the other planets that orbit it.” Juno is the first solar-powered spacecraft designed to operate so far from the Sun. Generating sufficient power to operate the spacecraft requires a very large area of solar cells. The four-ton Juno spacecraft carries three 30-foot (9-meter) solar arrays festooned with 18,686 individual solar cells. At Earth’s distance from the Sun, the cells can generate about 14 kilowatts of electric. The further away from the sun the spacecraft is, the lower the power its solar cell will be able to generate.

Battery energy storage systems (ESSs) are becoming well established to help the grid integration of solar photovoltaic (PV) and wind energy, particularly in remote and island communities. It is important to understand the different roles that energy storage can play, including controlling ramp rates, smoothing, shaping, peak shaving and frequency regulation.
A thank-you letter to SEIA members summarizing some of the accomplishments of 2015
Using battery systems for peak shaving is highly beneficial; enabling a constant load on the engine ultimately leads to high efficiency and energy saving at the engine level.
Claudia Assis for MarketWatch: Nevada has turned into a sunny battleground for the future of solar in the U.S., with regulators there moving to make solar power less attractive to homeowners and businesses and pitching utilities against solar-power companies. SunRun Inc. on Thursday said it was pulling out of Nevada, which the company said will result in “hundreds” of job losses. A day earlier, SolarCity Corp. announced the same move, saying that about 550 jobs would be lost. The Solar Energy Industries Association estimates that nearly 6,000 people in Nevada are employed in the solar industry. Besides affecting jobs, the new rules cut down on the savings that many homeowners count on from going solar. Cont'd...
Off grid living will become more common place as energy storage & solar generation become more ubiquitous.
As the business case becomes more apparent - with fuel cells delivering both economic and environmental value - the list of corporate customers continues to grow.
Here are three key software driven technology majors who are outsiders in the utility industry but are still driving big innovations in the Smart Grid area
BY¬ DAVID GILBERT¬ For International Business Times: ¬ ¬ As cars become less about horsepower and torque and more about the technology inside, CES has become one of the most important showcases of the year for auto manufacturers. It's a sea¬ change in how cars are built and marketed,¬ with technology now the core, rather than an added feature. Connected, autonomous and electric vehicles will all be on display at CES 2016, with some of the world's most talk-about companies in the field looking to make a major impact. First up will be Faraday Future, the secretive startup based in Los Angeles and backed by a Chinese billionaire. It¬ is¬ set to unveil its first ever concept design on Jan.¬ 4, and while all the company has said so far is that it will be an electric vehicle, it is widely believed to feature autonomous capabilities. While Faraday Future¬ is a relative unknown, one of the world's biggest automotive companies, Ford, will also be at CES announcing news about the autonomous car it has been testing internally for several years. Among the announcements expected is apartnership with Google¬ to build some of Google's fleet of self-driving cars. ¬ Cont'd...
The big differentiator of TDP Turnkey Tracker is the fact that it's bundled with a complete services and support package.
The Hydrogen Station Equipment Performance device, or HyStEP, could reduce the time to commission new stations from months to just one week.
Support for new renewable energy resources will have the greatest impact on our energy by driving demand for improvements in alternative energy that will deliver health and environmental benefits, and will help change the way our electricity is produced.
