How many roofs to be energy independent? Just 0.5%

Helio — Wed, 30 Apr 2008 15:54:00 +0000

According to the Department of Energy, solar panels could, if placed on about 0.5% of America’s mainland landmass, provide for all of our current electricity needs.

Clean-energy fever is being fuelled by three things: high oil prices, fears over energy security and a growing concern about global warming. The provision of energy, the industry’s cheerleaders say, will change radically over the coming decades. Polluting coal-and gas-fired power stations will give way to cleaner alternatives such as solar and wind; fuels derived from plants and waste will supplant gasoline and diesel; and small, local forms of electricity generation will replace mammoth power stations feeding far-flung grids.

Tax-credit stalemate imperils green energy industry

Helio — Tue, 29 Apr 2008 22:20:00 +0000

From the media…In today's San Jose Mercury News by reporter, Matt Nauman: "Tax-credit stalemate imperils green energy industry." Two lobby groups, the American Wind Energy Association and the Solar Energy Industries Association put the potential job loss if the credits aren't renewed at 116,000 U.S. jobs.

In testimony given earlier this year, Applied Materials' Blair Sweezey said the extension of the renewable tax credit could create 55,000 jobs and generate $45 billion in economic investment in the
solar industry across the country. But, if the credits weren't renewed, he said 40,000 jobs could be lost through 2009.

At the Start of Solar Season…A Look at the History of Solar

Helio — Sat, 26 Apr 2008 19:40:00 +0000

What's a "solar season?" The time of the year when the harvest of the sun ray's for powering our homes and other devices is the most abundant. Just how far back have we humans used the sun for our purposes? The U.S. Department of Energy provides a fascinating look at "The History of Solar" in a timeline perfect for solar enthusiasts of all ages.

Some fascinating facts:

In 7th Century B.C., the first record of our use of solar, we adopted magnifying glass to concentrate the sun's rays to make fire and burn ants!

By 2nd Century B.C., the Greek Scientist, Archimedes, used the reflective properties of bronze shields to focus sunlight and set fire to the wooden ships from the Roman Empire, who were launching a military seige on Syracuse.

By 1st to the 4th Century A.D. the Romans started to use the sun's warmth in ways reminiscent of what we see today. They used large south facing windows stream solar heat , thus warming up the water in their famous bathhouses.

Reducing Energy vs. Reducing Energy Cost

Helio — Fri, 25 Apr 2008 00:51:00 +0000

An energy audit should address more than an inventory of your electrical equipment. It is important to understand how you use energy. Then we can understand how to reduce your energy usage. However as you can see in the figure above just reducing energy does not ensure a reduction in energy cost. For example, a ~30% reduction in energy may realize cost reduction because 50% of your fees are from Peak Demands, and more from Time of Use (TOU). An audit review should incorporate a balance between usage and how you’re billed for that usage in an effort to flatten the energy curve. Strategies to reduce peak demand, then time of use cost is of primary importance, then overall energy reduction will yield more linear cost reduction results.

CA Renewable Energy Legislation & the Call for Energy Audits

Helio — Fri, 25 Apr 2008 00:38:00 +0000

New California legislation has addressed the movement toward renewable energy and reduction of Greenhouse Gas (GHG) emissions. In 2005 Governor Arnold Schwarzenegger issued an executive order setting GHG emissions targets for the years 2010, 2020 and 2050. This order has now been passed as the Global Warming Solutions Act AB32. AB32 requires the reduction of GHG emissions to 2000 levels by 2010, and to 1990 levels by 2020. In order to effectively implement the program, AB 32 directs the California Air Resources Board (CARB) to develop appropriate regulations and establish a mandatory reporting system to track and monitor global warming emissions levels. CARB is also the agency that will enforce the new regulations.

Implementation of this program requires selected commercial industries to perform an energy audit this year to determine their baseline GHG level. HelioEMS can assist these companies in the Baseline Energy Audit and registering their baseline with CARB to meet the AB32 deadline.

Doing Their "Solar" Part for Earth Day!

Helio — Tue, 22 Apr 2008 16:54:00 +0000

The "nitty gritty" of why we celebrate Earth Day resonates strongly in the smiles of our children. The installation of solar power systems on every roof on the planet (best case scenario!), is one part of a complex set of solutions. Still, the why of "saving the Planet" is still "saving it for our kids, and our neighbors' children, and the children in other states, countries and all their children to come."

These kindergarteners sang their hearts out at a recent Earth Day dedication for the Hebrew Academy solar power system. The celebration took place at their Huntington Beach, CA campus.

For these children, some pretty special adults made the system happen for the school. "Green" visionary Rabbi Yitchak Newman is the dean of the school. From left to right in the "ribbon cutting" photo above are donors Charles Karp and Peter Shapiro, HelioPower's Steve LoRusso, Adrian Taylor of Sharp amd Mayor Debbie Cook. Sharp Solar Energy Solutions Group worked with integration firm, HelioPower, to insure the system was perfect! Huntington Beach Mayor Debbie Cook, an avid "green" supporter, came out and helped dedicate the system. You can see the performance of their solar electricity system by clicking here for the online monitoring portal.

It takes all of us working together to insure Earth Day can continue to be celebrated for decades to come!

"Sweet Spot for Solar" – GE calls for cheaper, cleaner energy

Helio — Tue, 22 Apr 2008 03:15:00 +0000

In today's headlines, NEW YORK (CNNMoney.com) — Jeff Immelt, chairman and CEO of General Electric, said Monday much of the technology to make energy generation cleaner and more efficient is available now. The challenge, however, is deploying it and making it cheaper.

CNNMoney.com staff writer, Steve Hargreaves, reports from an industry meeting sponsored by the Edison Electric Institute, a utility trade group.

Immelt said GE is investing in a wide range of energy technologies. He specifically mentioned solar as one that has great potential.
The cost of solar power should fall from 30 cents a kilowatt hour today to under 15 cents "in a relatively short time," he said. "That should open up a sweet spot for solar."
By comparison, American consumers currently pay about 10 cents an hour on average for electricity, according to the Energy Information Administration.
The U.S. utility industry will likely be a recipient of clean technologies developed outside the U.S., Immelt added, whether it be cleaner coal processes fine-tuned in China or renewable technology pioneered in Europe.
But he encouraged the industry and U.S. government to take the lead in capping greenhouse gas emissions and developing clean sources of energy.
"The time to act is now," he said. "When you lead in clean energy, you create jobs. This is a place the U.S. could lead."

News Update: CNNMoney.com report today:

NEW YORK (Associated Press) – Solar energy stocks jumped Friday as analysts said one of the sector's leaders is well positioned for revenue and earnings growth.

PacificCrest analyst Mark Bachman, in a client note about SunPower Corp., said domestic demand is "running ahead of expectations set just three months ago, attributed to the possible lapse of the investment tax credit. U.S. customers are pulling projects into 2008 to avoid the uncertainty."

Solar "industry is just beginning to reach its potential"

Helio — Thu, 17 Apr 2008 23:04:00 +0000

While some people wonder whether there's too much hot air in the clean-tech sector, the man who has advised California Gov. Arnold Schwarzenegger on environmental matters says the industry is just beginning to reach its potential.

This report according to Green Tech blog writer, Carl-Gustav Linden, today in his recap of a CNET.com interview of "California's green guru," Terry Tamminen.

Regardless of who sets up shop in the Oval Office in January, sweeping changes in federal energy and climate policy are expected to give the clean-tech industry a big boost, says Terry Tamminen, former director of the California Environment Protection Agency and now a clean-tech adviser for
Pegasus Capital Advisors.
