McKinsey Talks Energy and Climate at MIT

On November 21, 2016 Scott Nyquist of McKinsey & Company (http://www.mckinsey.com) spoke to the public at MIT's Sloan School (https://docs.google.com/forms/d/e/1FAIpQLSeTLrGhwLlrx3wx3eTYcnTX6pIS6iziw4RTLiYNL9uP0dWmVQ/viewform?c=0&w=1).

Over the next 20 years, there are projections for 80% more demand on resources as a result of growing populations and growing economic production.  However, higher energy intensity, efficiency, and slower GDP growth leads McKinsey and Company to consider a less than base case view.

McKinsey sees 74% of our energy still coming from fossil fuels by 2050, with an energy related CO2 peak by 2035, and a similar peak in transportation by 2025.  COP 21, the Paris Agreement, has businesses going ahead and beyond waiting for negotiation, regulations and governments.  Nyquist pointed us toward not only the Energy Transitions Commission (http://www.energy-transitions.org), 28 leaders from business who recognize that COP21 is not enough and are setting zero carbon as a planning goal but also the Oil and Gas Climate Initiative (http://www.oilandgasclimateinitiative.com), 10 companies with 20% of global oil and gas production, which has pledged $1 billion for low carbon technology.

The top 4 emitters, US, China, India, the EU, are planning 4 - 2.5% improvements per year in energy productivity now and that will continue.  China is forecast to exceed the EU, US, India combined in zero carbon energy growth over the next 20 years.  They will have a large nuclear component to their energy mix. Even the Saudis are diversifying from oil.

Autonomous and sharing vehicle systems may reduce transportation emissions dramatically by 2030.  Private cars are going away, says the Senior Partner in the Houston Office of McKinsey and Company and leader in both McKinsey's Energy Practice and the McKinsey Sustainability and Resource Productivity Network.

Solar electricity, photovoltaics, are expected to be competitive in most USA states by 2025. A third of the USA now finds solar electricity competitive with other energy sources, including, in some areas, natural gas, even without subsidies.  Solar is beyond the tipping point today, even with the election of Donald J Trump.  Utility clients are optimistic about the possibilities of storage and micro-grids but still waiting for the technology.  Nyquist did not directly address demand side management or advanced energy efficiency.

According to his conversations, fossil fuel companies understand that the carbon budget is 900 Gt of emissions to keep within the 2ºC increase in global temperature rise while fuel reserves are already 3-5 times that amount.  Scott Nyquist called out  the oil and gas industry and the Republican Party for their conduct on climate change.  The topic of stranded assets was not addressed in this talk.

Nyquist spoke almost exclusively of emissions without really exploring sinks.  All the carbon capture methods he mentioned,  briefly, were industrial.  He concentrated on sources of greenhouse gases rather than sinks, flows much, much more than stocks.  Geoengineering did not come up nor did the idea of geotherapy, amplifying existing natural carbon sinks by ecological design.

At the very beginning of his talk, Scott Nyquist said that there is geological evidence of sea level risings as much as one foot per decade.  That is the context in which McKinsey and Company are thinking about energy and climate change.

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 (http://www.dailykos.com/story/2007/6/30/352476/-).

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 (http://www.thriveenergy.co.in) and believe that there are others that are doing the same or better.  That's $1.4 billion in production costs (or less, given economies of scale) to supply everyone among the presently powerless or $200 million 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 (http://www.esencialessrl.com) 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 (https://www.indiegogo.com/projects/dominican-light-project-by-esenciales-j-s-srl--2#/)
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 annually 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
Source:  http://www.opensecrets.org/pres16/
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.

Free as in Sunlight

Found an interesting project while wandering through my usual haunts on the Internet the other day.  The Dominican Light Project (https://www.indiegogo.com/projects/dominican-light-project-by-esenciales-j-s-srl#/story) 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 (http://www.enersol.org), 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 (http://hubeventsnotes.blogspot.com/2014/04/green-energy-for-billion-poor.html) program in Bangladesh as well as the Solar Electric Light Company (SELCO) (http://www.dailykos.com/story/2008/11/7/650525/- ) 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 (http://www.dailykos.com/story/2014/11/18/1345878/-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 (https://youtu.be/u0mjqjgZ64E) - 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.
