In an earlier post about a recently released book, The Great Transition (by Lester Brown, Janet Larsen, Matt Roney, and Emily Adams), there are seven realities some may find surprising, behind the global transition (to clean, renewable energy away from nuclear and fossils). These facts are listed below and certainly worth more in-depth attention:

The Great Transition by Lester Brown and co-authors Janet Larsen, J. Matthew Roney, and Emily E. Adams

The Great Transition by Lester Brown and co-authors Janet Larsen, J. Matthew Roney, and Emily E. Adams

  1. Global adoption of solar appears unstoppable now that solar is so cheap.
  2. Wind power adoption is rapidly altering energy portfolios around the world.
  3. National and subnational energy policies are promoting renewables, and many geographies are considering a price on carbon.
  4. The financial sector is embracing renewables-and starting to turn against fossils and nuclear.
  5. Coal use is in decline in the United States and will likely fall at the global level far sooner than once thought possible.
  6. Transportation will move away from oil as electric vehicle fleets expand rapidly and bike- and car-sharing spreads.
  7. Nuclear is on the rocks thanks to rising costs and widespread safety concerns.

For more detailed facts and figures, (<–click, please ).  Lester Brown and his co-authors have carefully gathered and analyzed the data from the past and provided us a glimpse of what our future has in store. Finally, the inertia from the past is unearthed and we can see the dark curtain is being lifted from the horizon. Our glorious Renewable and Solar/Wind Future has finally arrived! The Dawn Is Here!

I would also like to invite you to view the video below, to listen to Lestser Brown’s urging for us to mobilize to save our civilization and be further informed of various data and information availed to us based on the careful gathering and analyzing of data by Lester Brown and his co-authors.

The Solar Tsunami WIll Take Powerwall & Powerpack Into An Industry Greater Than $21 Billion !

Share

Dear Friends, Visitors/Viewers/Readers,

Tesla Powerwall Specs final

(Please click on red links & note magenta)

Many of you may be curious about the first week post-announcement of Powerwall from our May 1, 2015 post. The reception for Tesla’s new batteries has been OVERWHELMING!!! These are how Bloomberg Business breaks down the $800 million of orders:

  • The Powerwall home batteries designed to be paired with rooftop solar systems received 38,000 reservations.
  • Some customers order more than one battery. Average reservation is somewhere from 1.5 to 2 batteries. Musk described the total demand as “more like 50,000 or 60,000″ batteries in early reservations.
  • The Powerwall comes in two designs at $3,000 or $3,500 each.
  • Total Powerwall orders so far is $178.8 million.
  • Tesla has received 2,500 reservations for the utility-scaled Powerpack, usually ordered/installed with “at least 10 Powerpacks”…equivalent to  25,000 units totally at 2.5 million kWh.
  • Musk tweeted last week that pricing for the Powerpack is $250 kWh.
  • Total Powerpack orders thus far is: $625 million.


So, Tesla’s grand total for battery reservations during the first week is $803.8 million! They sold out their first year’s production during the first week! It is no wonder they are already considering expanding the gigafactory after just one week!

 


Tesla is currently also working on projects with Target and Amazon and with electric utilities that include Southern California Electric and Texas-based OnCor. It is not only the individual home owners with distributed solar but utilities are also interested in building battery storage. Batteries can replace some peaker plants while strengthening the grid. With the cost of battery now falling as fast as the solar panels, some electricity from your outlet may soon be coming from battery storage. Powerwall & Powerpack, the cost effective battery storage, have now taken care of one of the arguments against solar, its intermittency. We are seeing the effect of first touch down of previously announced Solar Tsunami ! The world will be a cleaner, healthier, and better place, thanks to Elon Musk’s batteries and Solar Tsunami ! Perhaps Elon Musk’s American dream: a chicken in every pot, a Tesla in every garage powered by solar panels in the roof through Powerwall battery, will soon become a reality. Some people in the energy industry forecasted that although  currently $605 million industry, by 2024 it can very well become a $21 billion industry. Of course, many other experts in the field feel that number would be much bigger than $21 billion.

Tindo, World’s First Solar eBus

Share

Dear Friends, Visitors/Viewers/Readers,

Tindo solar powered ebus2 final

(Please click on red links & note magenta)

I’ve been wanting to share this piece with you for quite some time now because transportation is responsible for almost a third of the CO2 emissions in most developed nations. So I was thrilled to find out about Tindo, the world’s first Solar Electric Bus that are being used every day by the people of Adelaide, Australia, through the Adelaide City Council’s free Adelaide Connector Bus service.

Tindo, the Kauma Aboriginal name for sun, is the culmination of the Adelaide City Council’s eight-year project to deliver a pure electric community bus. Adelaide’s air conditioned 40-seater and low-maintenance Tindo solar ebus is designed by DesignLine International, a New Zealand company. Green public transportation such as Tindo solar ebus is one of the ways to help mitigate global warming. Tindo is recharged using solar PV system at the Adelaide Central Bus station.  The solar PV system on the Bus Station’s roof is currently Adelaide’s largest grid-connected system, generating 70,000 kWh (or 70 MWh)of zero carbon emissions electricity each year to offset the total energy required to recharge Tindo’s batteries. Much of the funding for this $550,000 solar PV system was  provided by the Australian Government through the Adelaide Solar City program, with the Adelaide City Council also committing significant funding. Adelaide City Council looks forward to the future when a fleet of solar buses will be serving throughout the city of Adelaide.

The Great Transition, Shifting From Fossil Fuels to Solar and Wind Energy

Share

Dear Friends, Visitors/Viewers/Readers,

The Great Transition by Lester Brown and co-authors Janet Larsen, J. Matthew Roney, and Emily E. Adams

The Great Transition by Lester Brown and co-authors Janet Larsen, J. Matthew Roney, and Emily E. Adams

(Please click on red links & note magenta)

Do you feel the change in the air? We truly are living in an exciting time! Every where I turn, I see the sign of change and transition, including an email that I’ve received few days ago from Earth Policy Institute, about the arrival of a new publication. This is a recently released book titled, The Great Transition, by Lester Brown with co-authors Janet Larsen, J. Matthew Roney, and Emily E. Adams. It is a summary presentation for the worldwide transition from fossil fuels to renewable sources of energy, Solar and Wind Energy. It lays out the rapidly evolving global shift toward cleaner sources of energy, driven by economics, policy, and the reality of accelerating climate change. The authors stress the fact that this shift represents a lasting change in the way we power our world in centuries to come.

As fossil fuel resources shrink, as air pollution worsens, and as concerns about climate instability cast a shadow over the future of coal, oil, and natural gas, a new world energy economy is emerging. The old economy, fueled largely by coal and oil, is being replaced with one powered by solar and wind energy.

The Great Transition details this trend, focusing on falling prices and rising adoption for wind, solar, electric vehicles, geothermal energy, and energy efficiency; and the emerging turn from coal, nuclear power, oil, and traditional transportation that is happening faster than anticipated.


Yes, as seen in some of our previous posts, the change will always be faster than many have previously anticipated.

The authors of The Great Transition have also kindly provided us with slides to be shared among people who are interested in the course of energy in human history. They have also helped to shatter some of the old myths popularized by detractors of Renewable Energy in this book. It’s a great read for those who want to have a better understanding of how our world have and will continue to transition from fossil fuels into Renewable Energy Age.  Educators and policy makers from different locations are encouraged to utilize this well synthesized information to mobilize or fix our energy system.

The Necessary Missing Piece Unveiled, Tesla Powerwall & Powerpack, by Elon Musk

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links & note magenta)

When Elon Musk speaks, we listen!

Elon Musk (Flickr: Elon Musk-The Summit 2013, CC Attrib-Heisenberg Media)

The electric enthusiasm is palpable in the auditorium! One can feel the energy is ready to boil over….for this is what we (The World) have all been waiting for, the cost effective battery storage technology that would enable us to truly see the transformation of our world!  Let this very historical date be remembered, Tesla Motors, rather, Elon Musk, announces the arrival of Tesla Powerwall, on April 30, 2015 in LA.

I’ve been following the progress made by Tesla Motors for quite some times for it is critically connected to the future of our Solar Energy. The intermittency  of solar energy depends on the rate of progress or research being made in battery technology in the electric vehicle/auto industry. As Elon refers to the Sun as “this handy fusion reactor in the sky…producing ridiculous amount of power,” he also points out the amount of surface area needed for solar panels to power the entire U.S.A. is rather small (and mostly in solar rooftops). Furthermore, the size of the battery required to transition all of U.S.A. to Solar With Battery would only be 1 pixel…to no longer needing fossil fuel to generate electricity! But there are shortcomings in existing battery technology:

  • expensive
  • unreliable
  • poor integration
  • poor lifetime
  • low efficiency
  • not scalable
  • unattractive

To overcome these shortcomings, Elon unveils for us, on this very memorable day of April 30, 2015, The Tesla Powerwall !  Imagine our future world where batteries would be space-efficient wall-mounted, with a simple and elegant design (choices of colors), with integrated safety systems, thermal control, and dc-dc converter. It would work well with our solar systems. It would enable us to be free from worries about power outage and even potentially go off grid. At the cost of $3,500 (for the 10kWh version and $3,000 for the 7 kWh version)  it is the best affordable safe solution to our energy concern. It is also possible to stack up to 9 Powerwalls together, enabling 90 kWh.  This is a fantastic solution especially for area with intermittent energy source or remote area: residents from these areas would now be able to meet their energy needs through “Solar Panels with Tesla Powerwall” without the need of electricity lines. This will propell the progress of many remote areas.

Tesla Powerwall Specs final

You can order the Tesla Powerwall now by going to teslaenergy.com or teslapowerwall.com . They will start shipping in about 3-4 months. More will be ramping up next year as the transition will be made into Tesla Gigafactory in Nevada.

Toward the end of the presentation, Elon also brought forth the larger, scalable Powerpack, designed to scale infinitely. An order by a utility for 250 MWh installation (using Powerpack) has already been placed.  For dramatic effect, of course, we’ve been presented with the demonstration in an auditorium that is completely powered by the Sun, with storage by the Tesla Powerwall.

To demonstrate the feasibility of transitioning our world into renewable energy world—100% Solar (primarily)/Wind Energy, Elon has also shown us the data for such transitions:

  • 16,000 GWh from 160 million powerpacks (for U.S.A.)
  • 90,000 GWh from 900 million powerpacks (for the world)..primarily solar
  • 200,000 GWh from 2 billion powerpacks (for all transport, electric generation, and heating included)

THANK YOU, ELON! I’ve known that Solar/Renweable energy is the way to go more than 30 years ago (I’m sure that I was not alone), but it took some one like you to help to show us how it can be done!

THANK YOU, ELON, for making the designs and plans of gigafactory all open source! So, we earthlings will be able to transition quickly!

I am looking forward to the day when CO2 emission will be a thing of the past. Oh, what a clean, efficient, and smart world we will all live in!

Our future will be bright and sunny because there are people such as Elon Musk on planet earth…who may soon be on other planet(s), with the help of SpaceX!

It is designed by Toyo Ito, the first stadium in the world completely powered by the Sun, producing 100% of its electric energy from solar PV.  It is otherwise known as the National Stadium (official name) (Chinese: 國家體育場; pinyin: Guójiā Tǐyùchǎng; also named 龍騰體育場), formerly known as the World Games Stadium, is a multi-purpose stadium in Zuoying District, Kaohsiung, Taiwan. It is currently the largest stadium in Taiwan in terms of capacity. The stadium has a capacity of 55,000 people. Since the conclusion of the World Games2009, the stadium has been used for some Taiwanese football team matches. Its semi-spiral shape, like a dragon, utilizes its 14,155 sq meters (8,844 solar panels, generating 1.14 million kWh annually) of solar roof to power the stadium and its 3,300 lights and two jumbo vision screens. To illustrate the incredible power of this system, officials ran a test and found that it took just six minutes to power up the stadium’s entire lighting system! I imagine people from Taiwan will continue to amaze us with various progressive solar projects in the decades to come.

Agora Garden Tower of Taipei Taiwan, Helical Force of Life, by Vincent Callebaut Architectures

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links & note magenta)


“The future belongs to those who believe in the beauty of their dreams!”

“Le futur appartient a ceux qui croient a la beaute de leurs reves!”

~ Eleanor Roosevelt ~

If such were the case, then people from Taiwan are simply some of the most beautiful dreamers on this planet. During the month of February of 2015,  I had the opportunity to visit Taiwan. Its neighboring states include the People’s Republic of China to the west, Japan to the east and northeast, and the Philippines to the south. Its former name Formosa dates back to 1542 when Portuguese sailors sighted the main island of Taiwan and named it Ilha Formosa, meaning “beautiful island“.

Taipei is the seat of the central government. New Taipei City, encompassing the metropolitan area surrounding Taipei proper, is the most populous city.


During the latter half of the 20th century, Taiwan experienced rapid economic growth and  industrialization and is now an advanced industrial economy. Taiwan is one of the Four Asian Tigers and a member of the WTO and APEC. Its high-tech industry plays a key role in the global economy, enabling its status of being the 21st-largest economy in the world. Considering the fact that Taiwan only has a total area of 36,193 sq km (or 13,974 sq mi), its residents/citizens must be magical.

Taiwain, Taipei, Taiwan Strait (Public Domain)

Taiwain, Taipei, Taiwan Strait (Public Domain)

Upon closer examination, one realizes some of the significant contributing factors to Taiwan’s success story: it is ranked highly in terms of freedom of the press, health care, public education, economic freedom, and human development.

To summarize my overall impression of  Taipei, Taiwan: it is one of the most civilized 21st century cities in the world! It is a city where people are polite, orderly, and considerate, with the cleanest subway system I’ve ever seen where not a single piece of trash could be found !

It is not surprising that one would be able to find some of the most progressive and aesthetically intriguing architectural designs in Taiwan, as seen above and below  in the Agora Garden Tower design by Vincent Callebaut Architectures SARL  and various projects. It is a new sustainable residential tower in Taipei currently under construction to be completed in 2016. In the center of Xinyin District of Taipei, the Agora Garden project (as the name suggests,  Agora, in ancient Greece, means a public open space used for assemblies and markets) aims at limiting its inhabitants’ ecologic footprints by building a vertical landscape with low energetic consumption on this last and only biggest parcel of land for residential use. It integrates the recycling of organic waste, used water, renewable energies, and various state-of-the-art nanotechnologies (BIPV solar PV, rain water recycling/harevesting, composts, etc.). The BIPV’s are placed in the pair of giant horizontal shades atop the building. Its trademark spiral is inspired by the double helix of the DNA molecule, suggestive of the life force it  brings to the city. Utilizing its helical twist through a 90 degree angle (at 4.5 degrees per level in this 20- level building), it is creating a series of “suspended open-air gardens”, superimposing vertically wide planted balconies of suspended orchards, organic vegetable gardens, aromatic gardens, and other medicinal gardens. Contrary to our historical perception of “buildings”, Vincent Callebaut has created a living organism in Agora, overpassing the passive role of most buildings as passive energy-consumers.  Agora is designed not only to be self-sufficient in terms of energy (electric, thermal, and alimentary), but has gone a step beyond to produce its own organic food while taking a dynamically fluid geometry!  I never thought I would see a building that would be able to project our human relationship to nature and our environment so musically! It is truly a Helical Force of Life!

Agora has answered the four main ecologic objectives:

  1. reduction of the climatic global warming
  2. protection of the nature and the biodiversity
  3. protection of the environment and the quality of life
  4. management of the natural resources and waste

I will look forward to the date of its completion. Until 2016, I invite you to visit Tao-Zhu Gardon or Agora Garden of Taipei, Taiwan by Vincent Callebaut Architectures and hope these dreamers in Taiwan will be bringing this Helical Force of Life into reality.

Space Age Solar Power Is Real & Is Here To Change The World

Share

Dear Friends, Visitors/Viewers/Readers,

Solar Power Satellite Concept (NASA)

Solar Power Satellite Concept (NASA, 1976)

(Please click on red links & note magenta)

Isn’t it terrific that in the process of searching for solution to one problem, the California Drought, in our previous post, one may be led to a new horizon that holds the promise to all critical earthly issues: Energy-Pollution-Water-International Conflicts-Local Economics. Such is the case when I came across the concept and video on “Seawater Desalination via Solar Power Satellites“. I felt the need to find out more about Solar Power Satellites for energy is the common denominator and deciding factor for economic growth, inflation, and national security.  There is great need for all earthlings to transition quickly from a paradigm with pollution to a new paradigm of clean energy and better quality of life. Solar Energy future truly holds the key for it creates the least amount of environmental risk compared to other alternative energy sources. Now, in order to reach the desired growth speed to meet the demand of our growing earthly population, Solar Powered Satellite or Space-Based Solar Power would be the ultimate answer to address all of these issues.

Years ago, space-based solar power was too expensive and impractical. But things have changed since then. “The topic appeared to be dead several years ago, but it has received new life in the last year and a half,” said John C. Mankins, former head of Advanced Concepts Studies at NASA Headquarters, at a “Green Series” lecture in the Pearl Young Theatre in 2008.

To recap a bit of history regarding Space Energy industry: Peter Glaser, a vice president at Arthur D. Little, invented the “Solar Power Satellite” in 1968. The patent for that satellite was received in 1973. The basic design concept of a space-based solar power system in the 1970s was inefficient, difficult to launch, had no automation and received negative feedback from the National Research Council (NRC) and the Congressional Office of Technology Assessment (OTA). Much have changed since 1973: We have increased solar power generation efficiency, increased efficiency in wireless power transmission, created easier launch capabilities and have a more retractable design that does not require any astronauts or space factories, as the 1970s version did.

John C. Mankins, former head of Advanced Concepts Studies at NASA Headquarters,  made the point that “you don’t need hundreds of billions of dollars to see if these new systems are economically viable.” He admits that we are faced with a “grand challenge,” in part because there is no U.S. organization responsible for both space programs and solar energy security. That was then,  now we have SpaceX, a company that has already improved/dramatically reduced the cost of space transport and launch.

At this point, please allow me to introduce you to several Solar-Based Solar Power concepts at wikipedia (illustrated above) and a gripping TED talk on Space Energy Presentation by Peter Sage, an international serial entrepreneur, below (There are two parts to this talk):

 

Be prepared to hear a lot more about Space-Based Solar Power in the coming decade! As you can see, fellow earthlings, it is necessary to collaborate globally in order to enable the success of such projects. Time to reinforce our Collaboration and Global Mentality for our coming century! We are looking forward to a future with the technology that is capable of transferring energy, on demand, any where on earth, in real time, as it’s needed, 24 hours a day. Nothing else can do that! It is truly the real promise of Space-Based Solar Power!

Governor Brown, Solar Desalination As The Solution To The Drying California

Share
The Drying of California map

The Drying of California map

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links & note magenta)


For the first time in California history, Gov. Jerry Brown ordered mandatory water use reductions on Wednesday, April 1, 2015.  No Foolin’!   Finally the state’s four-year drought had reached near-crisis proportions after a winter of record-low snowfalls.”This historic drought demands unprecedented action,” Brown said, standing on a patch of dry, brown grass in the Sierra Nevada mountains that is usually blanketed by up to 5 feet of snow. In an executive order, Gov. Brown directed the State Water Resources Control Board to impose a 25% reduction on the state’s 400 local water supply agencies (serving 90% of California residents). The agencies will be responsible for coming up with restrictions to cut back on water use and for monitoring compliance. State officials said the order would impose varying degrees of cutbacks on water use across the board — affecting homeowners, farms and other businesses, as well as the maintenance of cemeteries and golf courses.

“We’re in a new era,” Gov. Brown said. “The idea of your nice little green grass getting lots of water every day, that’s going to be a thing of the past.” The state had trouble reaching the 20% reduction target that Gov. Brown set in January 2014 when he issued a voluntary reduction order. The state water board has the power to impose fines on local water suppliers that fail to meet the reduction target set by the board over the coming weeks.

The California Republican Representative Kevin McCarthy, the House majority leader, said, “The current drought in California is devastating. Today’s order from governor should not only alarm Californians, but the entire nation should take notice that the most productive agriculture state in the country has entered uncharted territory. I’m from the Central Valley, and we know that we cannot conserve or ration our way out of this drought.”

To Gov. Brown and Rep. McCarthy, I’d like to say, “Consider Solar Desalination!” Below is taken from Wikipedia on the topic of solar powered desalination unit. There are  also several videos helping to explain the process of seawater desalination and various technologies of solar desalination, utilizing our abundant sea water. Historically, due to the great deal of energy that is required in seawater desalination, desalination has not been utilized much in USA. With the dramatically decreased cost of solar coming on scene, Solar Desalination is now more likely to be an economically feasible solution to the California drought. Please be sure to also view the last video on “Seawater Desalination via Solar Power Satellites” that will utilize the currently existing 27 oil rigs  and off-shore platforms to serve as receiving antennas for the power beams of space solar satellites, running salt water desalination plants and using excess energy to power homes, cities, and industries in California.

A solar powered desalination unit produces potable water from saline water through direct or indirect methods of desalination powered by sunlight. Countries such as Australia, Italy and Egypt have adopted this system as an alternative source of water for the population.

 

 

 

 Direct solar desalination produces distillate directly in the solar collector. An example would be a solar still which traps the Sun’s energy to obtain freshwater through the process of evaporation and condensation. Indirect solar desalination incorporates solar energy collection systems with conventional desalination systems such as multi-stage flash distillation, multiple effect evaporation, freeze separation or reverse osmosis to produce freshwater.

The intermittent nature of sunlight and its variable intensity throughout the day makes predicting its efficiency difficult. However, incorporating a thermal energy storage system solves this problem and ensures constant performance even during non-sunlight hours and cloudy days, improving overall efficiency.

There are some concerns regarding seawater desalination such as the efficiency level and environmental impacts that would need to be monitored continuously. But solar desalination may provide California with the viable solution, I am optimistic.
