Sun Boilers Create Solar Energy Like a Genie In a Bottle

Tuesday, September 1st, 2009

solar-water-heaters-on-roof.jpgIsraeli solar energy companies such as Solel Solar, Aora, Ormat technologies, and a host of others are now world leaders in the development of sun power to produce electricity. But Israel, a small country of 7 million, with more than half its land area being desert, has been a solar energy pioneer virtually since its beginning in 1948.

What is now fondly known to many Israelis as a “dude shemesh”  or  sun boiler, was invented by a guy named Levi Yissar back in the early 1950’s, when electricity was very expensive due to a severe energy shortage.

Obama’s Energy Programs: New Polll Shows Broad Public Support

Monday, August 31st, 2009

obama-energy-programs-poll.jpgA significant majority of Americans supports President Obama’s efforts to overhaul energy policy and a slight majority favors a controversial program to place a cap and price on carbon dioxide emissions, according to a Washington Post-ABC News poll.

The poll found that nearly 60 percent of Americans back administration and congressional efforts to combat climate change and develop renewable energy and 55 percent approve of Obama’s handling of the issue, compared with 30 percent who do not.

Building a Green Economy: Green Jobs, Transmission Lines & Microgrids

Monday, August 31st, 2009

transmission-lines-microgrid.jpgImperial County, tucked away in the southeastern corner of California, has long suffered from perennial unemployment rates exceeding 20 percent.

Yet Imperial County is also home to the “crown jewel” of all geothermal steam resources in the U.S., making it a prime spot to showcase how renewable energy can help spur the new green economy so enthusiastically touted by the Obama Administration.

Late December, the California Public Utilities Commission (CPUC) approved the construction of the $1.9 billion Sunrise PowerLink transmission line, which could send clean electricity from Imperial County to San Diego. However, the Center for Biological Diversity (CBD) petitioned the California Supreme Court last January to review this decision, citing San Diego Gas & Electric’s (SDG&E) refusal to guarantee that the transmission project would be reserved exclusively for renewable energy resources.

Green IT: Buildings Are Now Twittering Their Energy Consumption

Thursday, August 27th, 2009

University of Mississippi Twitter Updatesumissgym: Is it just me, or is it hot in here?

The social media craze has hit building automation, as the campus at the University of Mississippi will soon be broadcasting its energy consumption via Twitter and Facebook updates.

In partnership with smart grid company SmartSynch, Ole Miss has created online feeds (also via RSS) detailing several of its main buildings’ energy use, ostensibly to “alter behavior to reduce electricity consumption and carbon emissions.” The UMiss project will study consumption from lighting, temperature controls, and appliances. The organizations have created an online application to monitor and report the energy draw so that building operators can learn where energy is being wasted and implement new conservation strategies.

Green Aeronautics: Tooth Enamel Biomimicry Inspires Fuel Efficiency

Tuesday, August 25th, 2009

green-aeronautics-tooth-enamel-biomimicry-fuel-efficiency.jpgIt’s been a mystery: how can our teeth withstand such an enormous amount of pressure, over many years, when tooth enamel is only about as strong as glass?

A new study by Prof. Herzl Chai of Tel Aviv University’s School of Mechanical Engineering and his colleagues at the National Institute of Standards and Technology and George Washington University gives the answer. And it has applications in the field of green aeronautics.

The researchers applied varying degrees of mechanical pressure to hundreds of extracted teeth, and studied what occurred on the surface and deep inside them.

Small Hydropower Dams on Rise As Concerns Grow About Big Projects

Tuesday, August 25th, 2009

hydropower-dam-environmental-concerns.jpgThe number of small hydropower projects in the U.S. is increasing as utilities try to avoid concerns about the environmental impact of large dams, the Wall Street Journal reports.

The Federal Energy Regulatory Commission now has applications for 14,000 megawatts of hydropower projects — enough to power 7 million to 14 million homes — and most are located on small rivers, streams, and creeks. That figure is a 20 percent increase from two years ago.

As the number of projects grows in states such as Washington, Colorado, and Montana, environmentalists are beginning to raise objections to the small dams, which critics say can still block fish runs, interfere with whitewater rafting trips, and carve up wilderness habitat with roads, power lines, and other infrastructure.

IBM and Trilliant Team to Simplify Smart Grid

Tuesday, August 25th, 2009

ibm-trilliant-smart-grid-utility.jpgTurning the country’s vast islands of proprietary utility networks and isolated power equipment into an intelligent grid that manages the power going into homes, offices and factories will take decades and hundreds of billions of dollars. IBM is partnering with veteran energy efficiency and grid communications company Trilliant to ensure that the companies’ grid hardware and software will speak the same language.

The agreement to integrate IBM’s Websphere and Tivoli products for managing enterprise data into Trilliant’s smart grid communications system provides utilities with and end-to-end system for collecting information and administering grid operations.

Trilliant, which currently has more than 200 utility customers, provides technology that can relay information about power consumption and network performance from smart meters in homes, to utility equipment out in the field such as transformers and substations, and then on to centralized (head end) utility servers. The company will build its management system using Websphere’s application server and the Tivoli network management suite.

Clean Energy Policy Debate: Let’s Agree to Agree!

Tuesday, August 25th, 2009

Plug-in hybrid electric vehicle (PHEV) diagramAnyone watching the health care debate spread from Capitol Hill conference rooms to town halls nationwide knows that everyone agrees we need health care reform. The disagreement comes in determining what kind. Comprehensive tort reform fits under the heading and so would the implementation of a single-payer system, but the two solutions could not be much farther apart on the political spectrum. An apt analogy – as the summer vacation season comes to a close – may be the good old fashioned American road trip: the whole family knows the destination, but getting there is the tough part.

Smart Grid Needs High-Level Policy Push

Monday, August 24th, 2009

smart-grid-Lexington-Institute-energy-technology.jpgSome projects are just too big to let the private sector handle them alone. Updating our aging one-way system of centralized power production to a smart grid is one of those projects. Left mostly to its own initiative, the energy industry has done very little in technology innovation during the past fifty years to make the grid more efficient and to accommodate distributed power production.

The need is so clear that even a group that supports limited government agrees that building a smart grid that conserves energy, integrates renewables, and diminishes peak power requires the guiding hand of the federal government.

The Lexington Institute has published a paper that neatly summarizes the smart grid challenges, and concludes that “Just as the grid of today required presidential initiative, the smart grid will take a high-level policy push, too.” The public policy research group, which says it “actively opposes the unnecessary intrusion of the federal government into the commerce and culture of the nation,” adds that “Smart grid will most likely require federal, state and local government incentives” and that “Policy action is worthwhile to move promising technologies closer to full adoption.”
