Scotland’s Sustainable Renewable Technologies (SRT) comes up with the SOLAR PYRAMID
The Solar Powered Pyramid http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3947 18 Sept 13 The sight of solar panels on a rooftop mightn’t generally capture as much attention as it once did, but this installation certainly does.
Designed and installed by Scotland’s Sustainable Renewable Technologies (SRT), the 48.25 kW installation provides 85% of the power used by the pyramid-shaped headquarters of Survey Solutions at Bilston Glen, Loanhead, Edinburgh.
According to SRT, other solar companies approached to execute the installation shied away from the project; stating that it could not be done.
Design of the scaffolding system that would allow the panels to be positioned in place was quite a challenge, but even more so was the clients’ requirement that each face of the pyramid to be covered in solar panels must be a perfect triangle. There could be none of the stepping that would otherwise be seen with square solar cells of the cut-down panels along edges.
To achieve the “perfect triangle” effect wasn’t so much a case of high-tech wizardry, but more design ingenuity – the panels along the edge are dummies and do not generate power. The 193 panel array will provide a benefit to the building’s owners of around AUD$17,000 annually and avoid the creation of around 36 tonnes of carbon dioxide emissions each year.
The system was installed in July 2012 and has been nominated for this year’s Solar Power Portal Awards, which recognises good practice, professionalism, quality, safety and innovation in the UK’s solar industry.
The SRT installation is unsurprisingly in the “Most Innovative System Design,” category. Also not surprising is the comment from Tom King, SRT’s managing director, who said the installation was the most challenging project he has planned so far.
We imagine the project has resulted in all sorts of weird and wonderful design requests for Mr. King and his team.
Brazil cools on nuclear power plans; favors wind
Brazil will probably scale down its plans for new nuclear plants due to safety concerns following the 2011 radiation leak in Japan and pick up some of the slack with a “revolution” in wind power, the head of the government’s energy planning agency said.

Japan’s big electricity companies put obstacles in the way of renewable energy
Since there are no regulations defining grid access, the restrictions can be imposed at will by the major utilities.
In a survey by the Japan Renewable Energy Foundation, in Tokyo, as many as 60 solar power providers said they had given up selling power because of the grid access problems.
a major stumbling block for renewable energy,
Renewable energy push blunted as ad-hoc rules stymie private upstarts, Japan Times, KYODO SEP 15, 2013 Ever since Japan kicked off a system to encourage the use of renewable energy for electricity in July 2012, businesses, civic organizations and even local government bodies have been trying to break into the tightly held power market.
Under the so-called feed-in tariff system, utilities are required purchase any generated electricity derived from five types of renewable energy for a fixed price and a set time.
But the momentum seems to be slowing. Several potential power suppliers are dropping their bids after coming face to face with restrictions that make it difficult for them to link to the power grids run by the utilities, which are essentially monopolies. Continue reading
Power companies join in California’s Community Renewable Energy project
The group estimates that more than 20,000 residential ratepayers throughout California, each purchasing an average 5 KW share, will be able to participate in the program, as well as local schools, businesses, the military and the government.
California approves shared renewable energy program http://www.pv-magazine.com/news/details/beitrag/california-approves-shared-renewable-energy-program_100012727/#axzz2etkybguT 13. SEPTEMBER 2013 BY: IAN CLOVER
Approval of the largest program for shared renewable power in the U.S. passes in California, enabling schools, rental tenants and owners of homes in the shade to invest in solar energy projects. California’s Legislature has given the green light for the state’s “Green Tariff Shared Renewables Program”, which is the largest of its kind in the U.S. and will allow rental tenants, schools, cities and many other interested parties to invest in California’s renewable energy projects.
The program allows businesses and individuals to purchase shares in the renewable developments of three investor-owned utilities– Pacific Gas and Electric Co. (PG&E), San Diego Gas & Electric Co. (SDG&E), and Southern California Edison Co. (SCE) – in return for a greener electricity supply and, in the future at least, lower bills. Continue reading
Cost of renewable energy has halved since 2008
Analysis: 50% Reduction In Cost Of Renewable Energy Since 2008 Clean Technica, 11 Sept 13 (Very good graphs). Renewable energy becoming more cost-competitive with fossil fuels isn’t news – as technology improves and more clean power generation comes online, electricity without emissions gets cheaper. But one new analysis reveals just how shockingly cheap it’s gotten.
The levelized cost of electricity (LCOE) from wind and solar sources in America has fallen by more than 50% over the past four years, according to Lazard’s Levelized Cost of Energy Analysis 7.0, recently released by global financial advisor and asset manager firm Lazard Freres & Co.
Lazard’s analysis compared the LCOE for various renewable energy technologies to fossil fuels on a cost per megawatt hour (MWh) basis, including factors like US federal tax subsidies, fuel costs, geography, and capital costs.

Wind power to dismantle nuclear weapons
The Largest Federal Wind Farm Will Power The Dismantling Of Nuclear Weapons, Stan Alcorn, Co exist 10 Sept 13 “…..The largest federal wind power plant is now being built to power a facility that does most of the nuclear weapons dismantling in the United States.
At the Pantex in the wind-rich Texas panhandle, electricity will soon come from five massive turbines, to help “green the nuclear security enterprise.”….. The case for the project is largely economic. The 47 million kilowatt hours of energy the five massive turbines will deliver should provide of 65% of the plant’s energy needs. That will save $2.8 million annually over the course of the 18-year contract, according to Siemens–money that will be used to pay back the original investment…. it’s a smart investment in the long run. And Marks says it’s only the beginning. “We hope to expand the wind farm even beyond these five turbines,” she says. “There’s plenty of property there, and plenty of wind.” http://www.fastcoexist.com/3016748/the-largest-federal-wind-farm-will-power-the-dismantling-of-nuclear-weapons
Southern California planning new energy system, with San Onofre closed
Post-nuclear power grid takes shape UT San Diego, By Morgan Lee SEPT. 4, 2013 Responding to the retirement of the San Onofre nuclear plant, energy authorities are closing in on California’s solution for ensuring power supplies to San Diego and the Los Angeles Basin, outlining a plan that will come under scrutiny Monday in Sacramento.
Under a 10-page draft plan, state regulators and Southern California utilities are weighing measures that might revive generators at the San Onofre site to ensure adequate electricity imports……..
Cheaper solar cells with nanotechnology
Cheaper Solar Cells With Abundant Earth Materials http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3921 4 Sept 13 University of Alberta scientists have used nanotechnology to design a solar cell incorporating abundant-earth elements, which they say could lead to cheaper and more prolific solar power in off-grid areas.
The team’s work revolves around finding ways to lower the cost of print and spray-on solar technology using nanoparticle-based photovoltaic cells. Jillian Buriak, senior research officer of the UA’s National Institute for Nanotechnology and fellow researchers used two commonly occurring elements, zinc and phosphorous, to form zinc phosphide, a highly conductive and photosensitive nanoparticle. The team then invented a method for dissolving the nanocrystals into a red-coloured ink capable of absorbing light and transforming it to energy.
Buriak believes this photovoltaic ink is an important step towards mass production of solar power through roll-to-roll printing and spray-on techniques.
“Nanoparticle-based ‘inks’ could be used to literally paint or print solar cells or precise compositions,” she said.
“Half the world already lives off the grid, and with demand for electrical power expected to double by the year 2050, it is important that renewable energy sources like solar power are made more affordable by lowering the costs of manufacturing.”
According to the University, the advantage of using such abundant-earth elements in the solar research is that both materials are more plentiful than scarce materials such as cadmium and are free from manufacturing restrictions imposed on lead-based nanoparticles.
Team member Hosnay Mobarok of UA’s Faculty of Science discovered the method of turning the zinc phosphide nanoparticles into a photovoltaic liquid. Erik Luber, from the Faculty of Engineering then worked on making the film responsive to sunlight.
The team have built a prototype solar panel and are currently working on spray-coating larger solar cells to test their efficiencies.
The work, funded in part by the Natural Sciences and Engineering Research Council of Canada, has been published in the journal ACS Nano.
Gulf Cooperation Council showcases solar energy development
UAE And Saudi Arabia Evolving Into Solar Powerhouses http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3920 3 Sept 13 The United Arab Emirates and Saudi Arabia are leading the way among Gulf Cooperation Council (GCC) states in the deployment of solar power.
Combined, GCC countries have approximately 84 GW of solar farm projects in the pipeline due for completion by 2017; representing investment value of US$155 billion.
“Over the years, solar power has been acknowledged as the most promising source of renewable energy and GCC governments have demonstrated their keenness to shift from traditional energy sources to these low-cost and abundant alternatives,” said Derek Burston, Director of the UK-based Bowmedia, the organisers of Gulf Sol 2013.
“Direct radiation in many Middle Eastern countries exceeds 6 kWh per square metre per day, making for excellent solar potential. In addition, recent decreases in the costs of solar technologies coupled with rising electricity demand in these growing nations, if coupled with the right policies, could make the region a hub for solar expansion”.
Saudi Arabia aims to double its installed electricity capacity; a goal that will be achieved in part by the construction of 54 GW of renewable energy power stations by 2032, 41 GW of which will be solar.
The largest operating solar panel based power generation facility in the GCC region currently is Enviromena’s 10 MW PV plant in Masdar City, Abu Dhabi, UAE. Abu Dhabi has set a goal of generating 7% of its electricity from renewable sources by 2020.
The Gulf Sol 2013 summit will run from September 3 to 5 and aside from showcasing the latest in solar technology, the event will include sessions discussing the feasibility of solar power projects in remote areas, opportunities in the GCC for international companies and regulatory and policy frameworks for implementation of solar projects.
The Gulf Cooperation Council consists of six Middle Eastern countries – Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, Bahrain, and Oman. The alliance was formed in part to strengthen relations among its member countries.
Economic new world order under way now, with renewable energy
Investors risk being left behind by renewable energy, Financial Standard, 29 August 2013
Nanuk manages a long/short thematic global equity fund which invests in companies that are positively exposed to a long-term structural shift towards cleaner and more efficient energy generation, management and use.
Chadwick told Financial Standard that the economic turmoil created by the global financial crisis had distracted investors from developments in the renewable energy space which he believes can spark a “new world order” with clean energy over-taking old-world fossil fuel sources much faster than most people realise.
“Out of the carnage of the GFC, solar and wind energy is fast becoming cheaper than traditional energy. There’s been carnage in the stocks related to the industry and there exists a questionable corporate situation but the theme is underpinned by unavoidable fundamentals.”…… Continue reading
Look at this – World’s largest solar thermal energy plant
Take A Tour Of This Insane Solar Thermal Energy Plant (Excellent photos) GIZMODO ALISSA WALKER 30 AUG 13 Sometime in the next few months, the Ivanpah Solar Electric Generating System will flip the switch on the largest solar plant of its kind in the world: a 377-megawatt, 3500-acre solar thermal energy system. It’s located in California’s Mojave Desert, near the Nevada border, and it’s ridiculously big. ‘
‘I would suggest going to check it out in person during your next Vegas binge weekend, but from the 15 freeway it’s little more than a silvery blur — a rippling, mirage-like, silvery blur that feels like it might sear your retinas if you look at it too long.

127 countries now supporting renewable energy schemes
Renewable energy support schemes now present in 127 countries, report finds PV Magazine, 28. AUGUST 2013 | MARKETS & TRENDS, GLOBAL PV MARKETS, APPLICATIONS & INSTALLATIONS | BY: IAN CLOVER The Worldwatch Institute — an independent research organization based in Washington D.C. — reports that 127 countries worldwide have now enacted support schemes for renewable energy…….. Despite the economic downturn leaving a number of countries mired in recession and hamstrung by shrinking budgets, investment in renewable energy development and expansion has generally followed an upward trend, particularly in the solar photovoltaics industry, which has seen module costs fall by as much as 80% since 2008, and 20% since 2012.
At the beginning of this year, 66 countries offered tax incentives on renewable energy development, the report finds. And as the technology has proliferated, so has regional diversity.
In the middle of the decade, 58% of countries that enacted renewable energy support schemes were located in Europe and Central Asia. Today, that figure is slightly more than a third of the global total, with East Asia and the Pacific (21%), and Latin America and the Caribbean (LAC) following closely. http://www.pv-magazine.com/news/details/beitrag/renewable-energy-support-schemes-now-present-in-127-countries–report-finds_100012528/#ixzz2dOMWGZNk
China to replace coal by wind and solar energy, by 2030
China has already demonstrated what’s in store by reducing the cost of solar PV modules so much that they are now commonplace on roofs across the mortgage belt suburbs of Australia. Between one-in-10 and even as much as one-in-three households now have solar PV systems installed in the outer metropolitan suburbs of Sydney, Brisbane, Perth, Adelaide and Melbourne as well as several regional cities. Such an outcome wasn’t even dreamt about by the most wildly optimistic greenie just four years ago.
What Japan did for home entertainment equipment, China will do for clean energy
Wind & solar outpace coal in China by 2030 – Bloomberg Tristan Edis 28 Aug 13, Bloomberg New Energy Finance (BNEF) has released analysis which finds renewables will make up more than half of new power capacity growth in China to 2030, across a variety of plausible scenarios. By 2030 total installed capacity of renewable energy power plants will equal that of coal.
This study sought to examine how technological and economic changes might realistically alter the make-up and growth of China’s power sector. They found that coal’s dominance will be challenged by:
– faster technological improvement and cost reductions achieved by renewable energy technologies;
– increased social concern and, consequently, government regulation over environmental pollution;
– the prospects of shale gas, and;
– a potential price on carbon emissions. Continue reading
America could get to 75% renewable energy quite quickly
Billions of solar panels and millions of wind turbines
The good news is we are already getting these.
With An ‘All-Out’ Federal Renewable Energy Strategy, How Long Before We Could Be 100% Renewably Powered?, Forbes, Mark Rogowsky, Internet Entrepeneur, 22 Aug 13, Probably 20-30 years to get to 70-80%, but 80 years to get the last 20-30%.
Let’s clarify that the assumption here is that the United States actually decides to do this per the hypothetical. That means that for whatever reason, the politics has shifted massively from where it currently stands. There are a lot of roadblocks to 100% renewable energy, but relatively few toward mostly renewable energy — assuming you’ve solved the politics problem. Here’s what you need:
An integrated long-distance grid
You’ll be carrying a lot of wind from the Midwest, possibly from offshore in the East, and tons of solar from the Southwest long distances. So you’re going to want much better long-distance power lines, maybe even with superconducting trunks. This will let you use Arizona’s 5 pm sun to power Florida’s air conditioners at 8 pm. Is this trivial? No. Is it technologically impossible? Absolutely not.
Millions of electric cars
We use a lot of non-renewable fuel for transportation. We’re going to need electric vehicles to fix that. Continue reading
Solar energy shiningin Japan, amidst its nuclear nightmare
Japan Adds 2+ Gigawatts Of Solar PV by Energy Matters, 22 Aug 13, Japan’s love affair with solar blossoms while a massive radioactive contamination threat still looms large.
Renewable energy facilities that commenced operations during Japan’s 2012 fiscal year (1 April 2012 to March 31 2013) totaled 2.08 gigawatts capacity, equivalent to two nuclear reactors, said the nation’s Economy, Trade and Industry Ministry.
Of the 2.08 gigawatts, 1.98 gigawatts was contributed by residential, commercial and utility scale solar PV.
The Ministry describes Japan’s shift towards a renewable future as “smooth”, with an additional 1.28 gigawatts of renewables added to the nation’s energy infrastructure in April and May this year.
All told, the amount of renewable capacity approved between July 2012 and March this year was 21.09 gigawatts, meaning far more is yet to be built.
While solar is enjoying smooth sailing, the country’s nuclear industry is experiencing anything but; with crisis after crisis occurring at the crippled Fukushima nuclear power station…… http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3905
