Solar Electric Power to the People

I like direct action, positive protest that has immediate, practical, social and economic use.  
That's why I say, Solar IS Civil Defense - light, phone, battery can be supplied by a few square inches of solar electric panel.  The solar bike lights on my backpack over the last decade have proven the concept to my satisfaction (

Light, phone, battery are also entry level electricity for the 1.4 billion or so of us around the world who don't yet have access to reliable electric power.  Emergency preparedness at home, entry level solar power to the people who've never had it is essentially the same thing.
Bare minimum solar electricity for all, as long as the sun shines and the batteries hold out, is technically and practically feasible now.  
It is rapidly becoming affordable too.  

I know of one company that is reaching the price point of $1 per unit production costs for solar rechargeable lights ( and believe that there are others that are doing the same or better.  That's $1.4 in production costs (or less, given economies of scale) to supply everyone among the presently powerless or $200,000 if we start with one solar lighting system per family at a global average of 7 people per family.
How much more for delivery and setting up the infrastructure?  The Dominican Light Project ( is beginning to provide solar lights for every family in the Dominican Republic at a proposed cost of $5 each to the customer's door.  They raised some of their money through crowdfunding (
Bare minimum solar electricity for all, as long as the sun shines and the batteries hold out, is not only technically feasible but also affordable and practical now.
in 2015, the world's military forces spent $1,676.0 billion or $4.59 billion per day
2016 USA Presidential election spending to July 22, 2016:
Amount raised by candidates:  $904 million
Amount raised by Super PACS supporting them:  $492
Just for reference.
Conceivably, there could be ad hoc popular movement for crowd funding the end of electrical energy poverty within the next 3 to 5 years.  A day of what we spend on warfare or a US Presidential campaign could give everybody who needed a light, a light.  This is solar electric power to the people.
Now, add a bicycle or a hand-crank and you have two reliable sources of electricity day or night, by sunlight or muscle power.
Here are a few solar lighting buy one, give one programs:

Free as in Sunlight

Found an interesting project while wandering through my usual haunts on the Internet the other day.  The Dominican Light Project ( is an Indiegogo campaign with a goal of raising at least $25,000 over the month of May 2016 to give solar lanterns to 5000 families in the Dominican Republic.  "For every $25 raised with the Dominican Light Project on Indiegogo, five Dominicans will receive a solar lantern to provide them with a safe source of light. Each lantern provides 12 hours of bright, LED light per 6-8-hour charge and will also eliminate the health and fire risks associated with candles and kerosene lamps.”  Eventually, they’d like to give a solar lantern to every family in the Dominican Republic at an estimated cost of over $25 million.
This reminded me of another solar project in the  Dominican Republic that started in 1984, Enersol (, which developed the SOlar-BASed rural Electrification Concept (SO-BASEC): "an appropriate low-cost, practical, PV system that could be sold and installed by local PV supply micro-enterprises, with financing through a low-cost micro-credit payment plan managed by a local association, cooperative or NGO.”  This model would go on to influence the Grameen Shakti ( program in Bangladesh as well as the Solar Electric Light Company (SELCO) ( ) in India.

What I remember most about Enersol and their work was their insistence on builidng a local support infrastructure that would not only install but also maintain and repair the equipment.  "By 1990 Enersol’s training and assistance to local technicians and micro-credit programs had led to the electrification of 1,000 households and micro-enterprises” demonstrating "that solar electrification was an affordable and effective alternative to conventional grid systems and that it benefited the environment and contributed to local economic development as well.”  And that’s at 1984-1990 prices.

The Dominican Light Project estimates the cost of their solar lights at $5 each, 12 hours of light for every 6-8 hours of charging.  A few months ago, I had an email from Thrive Solar ( informing me that they’ve been able to build solar lights for $1 a piece in production costs in their Indian factory.
For years, I’ve been promoting the idea of Solar IS Civil Defense ( - what we are all supposed to have on hand in case of emergency:  flashlight, cell phone, radio, extra set of batteries - can be powered by a few square inches of solar electric panel.  Add a hand crank or bicycle generator and you have a reliable source of survival level electricity, day or night, by sunlight or muscle power.  This is also entry level electrical power for the 1.5 billion people around the world who do not yet have access to electricity.  

Civil defense at home and economic development abroad can be combined economically as a gift, a premium in a “buy one, give one” program, as a small business, and in many other configurations.  Sunlight is free and the technology for converting it to electricity is now within almost everyone’s grasp.

World Game Notes: MOOCs, Global Displays, and Existing Technological Opportunities

"Quite clearly, our task is predominantly metaphysical, for it is how to get all of humanity to educate itself swiftly enough to generate spontaneous behaviors that will avoid extinction."  R Buckminster Fuller
MOOC [Massive Open Online Course]: Power Agriculture: Sustainable Energy for Food
Feb 1st - March 27, 2016“Details: Around one third of the energy used worldwide goes into the production and processing of food from field to table. Given the current energy system mix, the agrifood industry sector is however heavily dependent on fossil fuel inputs for production, transport, processing and distribution, and contributes significantly to greenhouse gas emissions. With a continuously growing world population the need for food and for energy to produce it is increasing. At the same time millions of farmers and processors in developing countries and emerging economies lack access to clean energy technologies for irrigation, drying, cooling, storage and other processes. Powering Agriculture: An Energy Grand Challenge for Development (PAEGC) seeks to identify and support new and sustainable approaches to accelerate the development and deployment of clean energy solutions for increasing agriculture productivity and/or value in developing countries.”

There is now technology to show this and other MOOCs’ proceedings on, among other things, a dynamic spherical screen like the iGlobe (  Currently, MIT’s Program in Atmospheres, Oceans and Climate and the Department of Earth, Atmospheric, and Planetary Sciences is hosting a two foot diameter iGlobe. 
“If you have data or interactive models you'd like to see visualized on the sphere... learn how it can be done and to figure out better ways and how to present information using the iGlobe.  Or try to make a compelling environmental movie using the sphere, an auxiliary screen, and sound.  Or come if you'd just like to experiment with the way things look projected on a spherical surface.”

There are open sessions with the IGlobe display every Thursday in January 2016 from 11am to 12pm at MIT, Building 54-1827, 21 Ames Street, Cambridge, the Green Building, the tallest building on campus.  Glenn Flierl, Professor of Oceanography, is the host.
NOAA [National Oceanic and Atmospheric Administration] also has a program called Science on a Sphere, 
“a room sized, global display system that uses computers and video projectors to display planetary data onto a six foot diameter sphere, analogous to a giant animated globe. Researchers at NOAA developed Science On a Sphere® as an educational tool to help illustrate Earth System science to people of all ages.”

These ongoing activities approach R Buckminster Fuller’s idea of a World Game:  
The goal of the World Game is to "make the world work for 100% of humanity in the shortest possible time through spontaneous cooperation without ecological damage or disadvantage to anyone." 

Today, we have the technology to play the World Game online in real time with interactive maps and satellite images updated frequently.  Imagine World of Peacecraft or the Final Fantasy of a sustainable, restorative economy and ecology for everybody, all 100% of the human population with a significant number of that 100% participating as co-designers, for the benefit of all who will allow the benefit of all.

Zero Net Energy

Zero net energy is a growing body of practice in which buildings produce all the energy they consume.  It is the application of high efficiency construction in combination with renewable energy, usually solar or geothermal.  Sometimes it is also called net zero energy building.

I began to collect links to various zero net energy building projects around the world back in 2013 soon after, in the story I heard, Cambridge City Councillor Minka Van Beuzekom  proposed it as a building standard for a large development MIT is planning in East Cambridge.  That idea didn't fly (the development is part of an ecodistrict instead, as I understand it) but did lead to a task force which has prepared a path to zero net energy standards in the city.

The EU has adopted the building energy target of nearly zero and all new public buildings must be nearly zero-energy by 2018 with all new buildings, public or private, constructed to nearly zero-energy standards by the end of 2020.

CA has a 2020 zero net energy goal "focused on new residential construction, including single-family and low-rise multifamily (3 stories or less) buildings, as well as low and moderate income housing within these categories."

The knowledge and materials to build buildings that are comfortable without outside energy inputs through advances in energy efficiency and energy production on site have made zero net energy buildings practical and affordable.  They will only become more so as time goes on, examples accumulate, and experience grows.

Since we build about a million new residential units a year, nearly 1% of the units available, these changes in the way we shelter ourselves will have increasingly significant effects on our energy usage in the years and decades after 2020 in, at least, Cambridge, CA, and the EU.

Federal and state mandates are influencing how buildings and construction projects are being designed, constructed, and operated, as well. California’s recently passed building code revisions that require all new residential and commercial construction to achieve zero net energy by 2020 and 2030, respectively. Similarly, new requirements by the federal and state governments call for all new federal buildings to achieve zero net energy by 2030 and all new state buildings to be built as zero net energy facilities after 2025.

The Current Cost of Carbon

In April of 2015 at a forum on the British Columbia carbon tax at MIT, I heard Merran Smith of Clean Energy Canada ( say if you add up the GDP of all the individual countries which have some kind of price on carbon, either an emission trading scheme (ETS) or a direct tax, it adds up to 42% of global GDP now and, by the end of 2016 when another five provinces in China come on board, it will be over 50%. (You can hear and see Merran Smith say this at 28:20 into this video of the MIT event at ).

Having heard expert after expert say, "We need a price on carbon" in order to address climate change, this struck me.  Was Merran Smith correct?  Have we already begun to put a price on carbon?  Looking a little further, I found a variety of carbon pricing structures - carbon taxes, emissions trading schemes, and even internal prices on carbon from individual businesses.

The World Bank 2015 carbon report advance brief ( puts it a little differently than Clean Energy Canada:
"In 2015, about 40 national and over 20 subnational jurisdictions, representing almost a quarter of global greenhouse gas emissions (GHG), are putting a price on carbon...

"The total value of the emissions trading schemes (ETSs) reported in the State and Trends of Carbon Pricing 2014 report was about US$30 billion (US$32 billion to be precise). Despite the repeal of Australia’s Carbon Pricing Mechanism in July 2014, and mainly due to the launch of the Korean ETS and the expansion of GHG emissions coverage in the California and Quebec ETSs, the value of global ETSs as of April 1, 2015 increased slightly to about US$34 billion. In addition, carbon taxes around the world, valued for the first time in this report, are about US$14 billion. Combined, the value of the carbon pricing mechanisms globally in 2015 is estimated to be just under US$50 billion...

"In addition, the adoption of an internal carbon price in business strategies is spreading, even in regions where carbon pricing has not been legislated. Currently, at least 150 companies are using an internal price on carbon. These companies represent diverse sectors, including consumer goods, energy, finance, industry, manufacturing, and utilities."

However, the International Energy Agency's 2015 Special Report on Energy and Climate Change ( concludes that

"Carbon markets covered 11% of global energy-related emissions in 2014 and the average price was $7 per tonne of CO2. In contrast, 13% of CO2 emissions were linked to fossil-fuel use supported by consumption subsidies, equivalent to an implicit subsidy of $115 per tonne of CO2."

If I understand that correctly, it means we have a global average price of $7 per tonne on CO2 with an implicit subsidy of $115 per tonne for fossil fuels at the present moment.  Not that we can't change those figures over time.

The social cost of carbon the EPA now uses is about $40.  The cost of carbon project of EDF ( reports that

"The current social cost of carbon pollution estimates for a unit of emissions in 2015 are $57, $37, and $11 using discount rates of 2.5 percent, 3 percent, and 5 percent, respectively. The fourth social cost of carbon pollution estimate of $109 uses a 3 percent discount rate and describes the 95th-percentile value for the social cost figure, in an attempt to capture the damages associated with extreme climatic outcomes. The estimate of $37, which uses a 3 percent discount rate, is considered the “central” estimate for a unit of emissions in 2015.  That $37 value is denoted in 2007 USD and equals around $40 in today’s dollars."

Here are the current prices on some of the various ETS around the world:
Averaging around €7.30
"Respondents anticipate an average EU carbon price of 10.79 euros ($11.76) per metric ton (1.1023 tons) in the third phase of the Emissions Trading System (ETS), which runs from 2013 to 2020."

The British Columbia revenue neutral carbon tax started in 2008 with individually set taxes on gasoline, diesel, jet fuel, natural gas, propane, and coal (low heat value and high heat value).  By January 2013, the carbon tax contributed about $1 billion each year which was used to lower other income and other taxes in British Columbia.  BC now has Canada's lowest income tax rate.

Finland was the first country to enact a carbon tax in 1990.  Originally based only on carbon content, it has become a combination carbon/energy tax, currently €18.05 per tonne of CO2 (€66.2 per tonne of carbon) or $24.39 per tonne of CO2 ($89.39 per tonne of carbon) in U.S. dollars (using the August 17, 2007 exchange rate of USD 1.00= Euro 0.7405). 

Sweden began their carbon emissions tax in 1991. The tax is now $150/T CO2, with fuels used for electricity generation exempted, and industries are required to pay only 50% of the tax.

In October 2014, Chile enacted the first climate pollution tax in South America at $5 per metric ton of CO2 which begins in 2018 and applies to only 55% of emissions. 

Nearly 500 companies globally report that they are already regulated through global carbon markets.  96 (nearly 20%) of these are U.S. companies. Of these, 69 are participating in the EU ETS.

In addition, more and more private companies are adopting an internal carbon price, even in countries and regions where carbon pricing has not yet been legislated. Today, at least 150 companies are using an internal price on carbon ranging from $6 to $80 per ton with one outlier at $324. These companies represent diverse sectors, including consumer goods, energy, finance, industry, manufacturing, and utilities according to the Global Price on Carbon Report 2014 [pdf alert]
from CDP, "an international not-for- profit organization providing the only global system for companies and cities to measure, disclose, manage and share vital environmental information."
