More History – Circa 1997

This is the second of the two articles from the 1990s mentioned in the previous blog post. It was published in the November-December 1997 issue of Asia Pacific Economic Review.

Why We Must Move Toward Renewable Energy
by Allan R. Hoffman

Rapid economic growth in the Asia-Pacific region has been and will continue to be mirrored by a rapid increase in energy demand. Between 1970 and 1995 primary energy demand in the region increased from 19 to 70 Quads (quadrillion BTUs). This figure is expected to increase to 135 Quads in 2010 and to 159 Quads in 2015 (Source: Energy Information Administration International Energy Outlook, 1997). The World Bank has estimated that developing countries alone will require 5 million megawatts of new electrical capacity over the next four decades to meet the needs of their expanding economies. The world’s current total installed capacity is just under 3 million megawatts. Thus, even if the World Bank’s estimate is too optimistic, installed world generation capacity will essentially have to double during the next 40 years. This much new capacity will require trillions of dollars of new investment.

What does this mean for renewable electric technologies – I.e., electricity generated from solar, biomass, wind, geothermal and hydropower resources? Fossil fuels are likely to remain the dominant energy source through the middle of the next century, while renewables can anticipate capturing only a fraction of that market. Every one percent of the emerging market in developing countries represents $50-100 billion of investment. If renewables can capture several percent of that market, the potential exists for several hundred billion dollars of renewable technology sales worldwide over the next four decades. Why are renewables important? They are the most environmentally responsible technologies available for power generation. Most renewable technologies have proven effective and reliable. Efforts are underway to further improve their technological performance, which may be the easiest problem to solve.

Providing Access to Renewables for Developing Countries
The more difficult problems are how to get renewable technologies into people’s hands, how to pay for them, and how to set up the non-technological infrastructure needed for widespread deployment of renewables. In many applications, 
renewables are the least cost energy option. 
Thinking on energy costs is distorted in the 
United States because of relatively low 
energy prices. Outside the US the story is 
very different. Average electricity prices in 
Germany and Japan approach or exceed 
20 cents per kilowatt-hour. Even in remote 
parts of the US, such as Alaska, electricity prices range from 40 to 60 cents per kilowatt-hour. In many parts of the world, including remote areas of the Asia-Pacific 
region, it is hard to put a price on electricity because there is no access to it. The current world population is 5.8 billion people. 
It is estimated that more than 2 billion of 
those people have no access to electricity. 
In China alone that number is 120 million. 
At least another half billion people around the world have such limited or unreliable 
access to electricity, that for all intents and 
purposes they have no electricity. If we are 
to make a difference in these people’s lives, 
we have to make available to them free-standing power sources suitable for off- 
grid applications – i.e., renewable electric 
technologies. When people have no access 
to electricity, even a 35 watt photovoltaic 
panel or a small wind machine can make a 
very large difference in their lives. Where 
the alternative is to extend expensive electrical transmission and distribution systems, use of these technologies can be cost 
effective.

What is the status of renewable 
technologies today? Costs for photovoltaics, the use of semiconductor materials to 
convert sunlight directly into electricity, 
have come down from approximately $1 per kWh in 1980 to 20-30 cents per kWh 
today. With increasing scales of manufacturing and increasing emphasis on thin-film devices, electricity costs from photovoltaics are expected to fall below 10 cents 
per kilowatt-hour early in the next decade. 
Current annual world production has just 
exceeded 100 megawatts, and is growing 
at more than 20 percent per year. This corresponds to a doubling time of less than 4 
years. Current US. production capacity (40 
megawatts per year) is fully subscribed, 
and half a dozen new or expanded manufacturing plants are scheduled for operation within the next 18 months. Roughly 
70 percent of US. production is currently 
exported.

The “3- Flavors” of Solar Thermal 

Another form of solar energy, solar thermal technology, concentrates sunlight to 
create heat that can then be used to generate stearn and/or electricity. This technology comes in 3 “flavors”: troughs that con
centrate sunlight along the axis of parabolic 
collectors; power towers that surround a 
central receiver with a field of concentrating mirrors called heliostats; and dish-engine systems that use radar-type dishes to 
focus sunlight on heat-driven engines such 
as the Sterling engine. Electricity costs from 
the parabolic trough units are in the 10 to 
12 cents per kilowatt-hour range, but can 
be reduced. Costs of electricity from the 
other two solar thermal technologies are 
expected to be even lower than those of the 
parabolic trough systems, and could reach 
4 to 6 cents per kilowatt-hour when manufactured in commercial quantities.

The world has large resources of organic 
material, called biomass, which occurs in a 
variety of forms (wood, grasses, crops and 
crop residues). Biomass can be converted 
into energy in a number of ways. As wood-burning fuel, it has been used extensively 
in developing parts of the world, often resulting in widespread deforestation, soil 
loss, declining farm productivity, and increasing likelihood of seasonal flooding. In 
future, the most effective way to use biomass is likely to be gasification, where the 
resulting gas can either be used as fuel for 
high efficiency combustion turbines, or as 
synthesis material for producing liquid fuels. The US Department of Energy (DOE) 
has a series of projects underway to determine how to most effectively use biomass 
for energy production. DOE is experimenting with biomass-coal co-firing in New 
York state, biogasification with bagasse 
(the residue from sugar cane) in Hawaii, 
with wood in Vermont, with switchgrass 
in Iowa, and with alfalfa in Minnesota. Biomass-based electricity has the advantage 
of being a baseload technology (i.e., it can 
be operated 24 hours a day) and is carbon 
dioxide neutral – i.e., the carbon dioxide 
released during its use is recaptured by the 
biomass during its growth. The revenue 
derived from the sale of biomass resources 
can be an important component in rural 
economic development. Costs for biomass-generated electricity are expected to be 
competitive as long as biomass resource 
costs remain reasonable.

Europe “Blows with the Wind”
Many locations offer wind resources. Wind 
is the fastest growing energy technology 
in the world today. Most ofthe 17,000 wind 
turbines in the United States are located in 
California, but a dozen U.S. states (from the 
Dakotas south to Texas) have greater wind 
potential. Today’s highly reliable machines 
(typically available 95-98% of the time) provide electricity at 5 cents per kilowatt-hour 
at moderate wind sites. The next generation of turbines, currently under development, should provide electricity at half that 
cost. Use of wind energy is expanding rapidly in many parts of the world, with 
Europe’s installed capacity now exceeding 
that of the United States (4,000 megawatts 
compared to 1,700 megawatts). India ranks 
third with 800 megawatts of wind generated capacity. Large wind generation 
projects are also being planned for China and other parts of the developing world. 
Geothermal resources – i.e. hot water or 
steam derived from reservoirs below the 
surface of the earth – were first used to generate electricity in Italy in 1904. Today, more 
than 6,000 megawatts of geothermal power 
are installed world wide, with about half of 
that in the United States. Rapid expansion 
of geothermal power is taking place in several places around the world, most notably in Indonesia, the Philippines, Mexico 
and Central America. Geothermal power 
is a baseload technology. It can be a low 
cost option if the hot water or steam re
source is at a high temperature. One California geothermal project produces electricity at 3.5 cents per kilowatt-hour.

Limit to Fossil Fuels?
Given the world energy situation, one can
not project today’s energy system into the 
long-term future. Fossil fuels will continue 
to be the primary fuel source for years to 
come. As history has shown, the transition to a different energy system is likely 
to take 50 to 100 years. The world cannot 
continue to be dependent on fossil fuels. 
Transportation issues are a good example 
of this misplaced reliance. If a reasonable 
fraction of the large and growing populations of China and India start driving cars 
as people in the developed world do, demand and prices for petroleum resources 
will grow rapidly, causing serious international supply problems and political ten
sion; unacceptable environmental consequences will affect us all. There is a limit 
to the Earth’s fossil fuel reserves. Whether 
it takes 50 years, 100 years or longer, these 
reserves will run out. The head of Shell 
UK, Ltd., a highly respected oil industry 
planning organization, has said: “There is 
clearly a limit to fossil fuels. Fossil fuel resources and supplies are likely to peak at 
around 2030, before declining slowly. Far 
more important will be the contribution of 
alternative renewable energy supply.” For 
many reasons, financial and otherwise, 
nuclear power is not likely to meet the energy needs of developing countries. Hydro
power is the most mature form of renewable energy and already provides a significant share of the world’s electricity. Though 
potential exists for further hydropower developement in many parts of the developing 
world, significant hydropower expansion in 
developed countries is unlikely to occur 
because of environmental concerns. With 
limited choices, the world is entering the 
early stages of an inevitable transition to a 
sustainable world energy system dependent 
on renewable energy resources.

A bit of history – circa October 1995

While going through some files recently I came across several articles from my days in the Bill Clinton Administration, first as Associate Deputy Assistant Secretary and then as Acting Deputy Assistant Secretary for DOE’s Office of Utility Technologies (OUT). This Office had responsibility for developing the full range of renewable electric technologies as well as hydrogen and energy storage technologies. In reading these articles twenty years later I am struck by how my words were in many ways the same then as now. What has changed is the development status of the technologies, their costs, the extent of their deployment, and the enhanced understanding of global warming and its implications for climate change. I have selected two of these articles for republishing in this blog. The first, from 1995, is republished below to provide a bit of historical context for the changes that are occurring today in our energy systems. It was part of a newsletter set up to improve communications between the leadership and staff of OUT. The second, from 1997, will be published in my next blog post. In a subsequent blog post I will offer my thoughts on what Donald Trump’s election as U.S. President could mean for U.S. energy and environmental policies and programs.

From the Desk of the ADAS:
Allan Hoffman
October 1995

”A vision helps us stick to our beliefs and keep going in the face of resistance, chaos, uncertainty and the
inevitable setbacks. ”

In thinking about what to say in this piece, I realized that much of what I say in speeches outside of the
Department is often not shared with my OUT colleagues. So, given this opportunity, let me share some of my
thoughts on the “vision thing” and related ideas that I often introduce in my presentations. Your comments
and reactions will be appreciated – whether by e-mail. memo, telephone or hallway conversation.

I sometimes begin my remarks by observing that it has been approximately one generation since the Oil Embargo of 1973, the point at which world attention began to focus intensively on energy issues. An often quoted rule-of-thumb is that it takes about a generation for new ideas to begin to penetrate the mainstream. This is the point we find ourselves at today for non-hydro renewable electric technologies. Considerable progress has occurred over the past two decades in improving technological performance and reducing associated energy costs of wind, photovoltaic, solar thermal, biomass and geothermal energy systems – e.g., at least a five-fold decrease in the cost of PV electricity, and the availability of highly reliable wind turbines that can generate electricity at 5 cents per kilowatt-hour in moderate wind regimes. This has brought us to a point where, under certain conditions, renewable technologies can be the low cost option for generating power, presaging significant deployment of these technologies in developed as well as developing countries. In addition, increased deployment of renewables is being driven by concern for the environment (e.g., global climate change) and energy security, and the recognition that widespread use of renewables represents markets in the trillions of dollars. To put some numbers into the discussion, the World Bank has estimated that, over the next 30-40 years, developing countries alone will require 5,000,000 megawatts of new generating capacity. This compares with a total world capacity of about 3,000,000 megawatts today. At a capital cost of $1-2,000 per kilowatt, this corresponds to $5-10 trillion, exclusive of associated infrastructure costs. It is the size of these numbers that is generating increased interest in renewables by businesses and the in- vestment community. It is also the reason for the increasing global competition for renewable energy markets. In addition, and very importantly, the environmental implications of that much capacity using fossil fuels, even in the more benign form of natural gas, are severe. If we are to minimize adverse local and global environmental impacts from the inevitable powering up of developing nations, renewable or other forms of non-polluting and non-greenhouse-gas-emitting power systems must be widely used. In the minds of some nuclear power offers a solution, but the scale of nuclear power plants is often not consistent with the needs or financial condition of developing nations, and the social issues that come with the associated handling of plutonium and radioactive wastes need to be carefully considered by society before it embarks on this path.

Given these considerations the prospect that fossil fuel supplies will begin to diminish before the middle
of the next century, and the need to move to sustainable economic systems, I see no alternative to a gradual
but inevitable transition to a global energy system largely dependent on renewable energy. Previous energy
transitions, e.g., from wood to coal and coal to oil, have taken 50 to 100 years to occur, and I see no
difference in this case. I also believe that over this time period, hydrogen will emerge as an important energy
carrier to complement electricity, given its ability to be used in all end use sectors and its benign
environmental characteristics. In this vision, all renewables will be widely used: biomass for fuels and power
generation, geothermal in selected locations for power generation and direct heating, and wind, hydro,
photovoltaics and solar thermal (in its various flavors) for power generation. Particular applications will be
tailored to’particular local situations. Large amounts of renewable power generated in dedicated regions
(e.g., wind in the Midwest and solar in the Southwest) will be transmitted thousands of miles over high voltage
DC power lines to distant load centers. And, electricity and the services it provides will be available to almost
every one on the planet.

One final word: why is it important to have a vision? My answer is that at the beginning of a major transition, one that will surely be resisted by well-entrenched and powerful vested interests, there will be a certain amount of chaos, a large degree of uncertainty, and setbacks. In the words of the late author Barbara Tuchman, “In the midst of events there is no perspective.” This places a heightened responsibility on the OUT staff and others to keep up their efforts to continue improving the technologies and reducing their costs. A vision helps us stick to our beliefs and keep going in the face of the resistance, chaos, uncertainty and the inevitable setbacks.
Without vIsion, very few transformational events in human history would have occurred.

A Presidential Campaign Speech from 2052

(Note to my readers: please allow me this ‘indulgence’ as it allows me to discuss what I see coming in the energy field.)

My fellow Americans, I am pleased to announce today my candidacy for President of the United State. We have just turned the corner on the first half of the 21st century, a time of significant change for our country and many other countries. In 2052 it is time to consolidate and reaffirm those changes that are beneficial, and plan for the coming decades. The 21st century has been an American century, but not exclusively – other parts of the world have demonstrated global leadership both economically and politically in these past 50 years – and it is encumbent on a new set of U.S. leaders to continue the American century in peaceful and meaningful cooperation with our global partners. Before discussing my plans for the future I would like to review what I see as the history and the accomplishments of the century’s first fifty years.

The century began as an extension of the 20th century – multiple national conflicts, internal dissension in many countries, and heavy dependence on traditional fuels such as coal, oil and natural gas. Global population continued to increase – having grown from 1.8 billion to more than 6 billion in the past century – and is expected to reach as much as 10 billion sometime before the turn of the current century. That number in 2052 is just under eight billion.

Increasing electrification was an important characteristic of the 20th century and will continue to define the 21st century as well. It is allowing increasing numbers of people to enjoy the energy services that access to electricity and other forms of energy brings – lighting, heating, cooling, communication, transportation, and the ability to make things quickly and in quantity. Today, fewer than five percent of the world’s population lacks access to reliable electricity supplies, and this number should reach zero in the next two decades. Essentially all have access to wireless devices that allow widespread communication and access to the world’s store of information.

This access to energy, the closely related access to clean water, and wireless capability have significantly reduced global poverty and greatly enhanced opportunities for learning. The education revolution that has been made possible by universal access to the internet, for both women and men, and the individualized learning that the computer revolution has made possible, together with energy access, has finally allowed a slowdown in the rate of population growth so that a stabilized global population may be achievable in my lifetime.

This century has also seen other powerful changes. In 2008 our country elected its first black President, and then reelected him in 2012 as affirmation of their good judgement four years before. In 2016 the U.S., after a lengthy and often nasty presidential campaign, elected its first female president, who once and for all showed that women can serve effectively at the highest levels of our political life. Together with the military opening all its ranks to female participation in 2015, the so-called ‘glass ceiling’ was finally shattered, never to be restored. That election also saw the election of a Vice President of Hispanic ethnicity, who eventually went on to become the 47th President of the United States. Today I am trying to shatter still another political barrier by attempting to become the first Muslim American to receive the nomination for President of a major political party.

While much has changed in the past five decades, and I will discuss one of the most important changes in detail shortly, not everything has changed, unfortunately. We are still human beings, with all our many shortcomings, and religious and racial intolerance are still major sources of pain and conflict in the modern world. While the threat of Islamic jihadism that arose forcefully in the first few decades of the century has been reduced significantly through the actions of a global coalition of Muslim and non-Muslim governments, remnants are still with us and require careful attention. As our President I would commit all the resources needed, in cooperation with our allies, to keep this threat under control. A major factor in controlling this threat has been the willingness of Sunni and Shiite governments to put aside their religious differences In the name of their overriding commonality, Islam.

Among the other changes we have seen in our lifetime is the establishment of the first human colonies on the moon and on Mars. The moon colony was a joint U.S.-Chinese achievement in 2032, just twenty years ago, and the first Mars colony of four people was established just 8 years ago, in 2044. Both were extraordinary events at the time, and commanded global attention, but as is true of so many achievements in outer space the existence of the colonies is becoming part of the background. That is an OK result as we want space travel to become a routine part of the mainstream.

Other major steps forward have been in the field of medicine. With advances in DNA measurement and manipulation personalized treatment has become routine for many gene-related diseases. It is not unusual today to see people living into their second centuries and still functioning normally. Of course the social security and related safety-net systems in the U.S. have had to be adjusted for this new longevity, and as you might expect, only after long and difficult political battles.

Finally, let me talk in some detail about the most important revolution of the 21st century, one I have worked hard to support in my current position as a U.S. Senator. It is one that I am committed to support and advance if I am privileged to serve as your President. That is the energy revolution that started in the latter part of the 20th century, took flight during the early decades of the 21st, and is today reaching all parts of the globe. It is a transition point in human history.

The 1973-74 Oil Embargo, which took place almost a century ago, was a brutal wake up call for many nations, including our own. The history books tell many stories about how Americans, for the first time, began to look at energy issues in a different light. Prior to the Embargo energy costs were sufficiently low that it was not an area of public concern. Then, one day Americans awakened to the fact that much of their energy, especially for transportation, was imported from abroad, and that such supplies were subject to political uncertainties beyond our control. This was true in the countries of Western Europe as well. We responded by creating the International Energy Agency, a mechanism for sharing oil reserves among countries if another embargo threatened our energy supplies. We also started looking at energy alternatives, with particular emphasis on nuclear power. In fact the public mantra at that time by our political leaders was a doubling every decade of the number of nuclear power plants deployed in the U.S. A few others raised concerns about nuclear power and called for examination of enhanced energy efficiency and renewable energy alternatives. Until that time renewable energy had not been seriously considered except in the case of hydroelectricity. The suggestion related to enhanced energy efficiency was dismissed by economists and others who saw economic growth (GDP) tied one-to-one with energy consumption, and renewables were attacked as too expensive and incapable of meeting the demands of the U.S. economy. These arguments persisted for several decades until it was shown that GDP and energy consumption were not directly linked, climate change associated with combustion of fossil fuels became a major global issue, the costs of renewable energy systems began to decrease, and the ability of renewable energy in the form of electricity, biofuels, and heat were shown capable of supporting large economies. These new realities became the focus of policy debates in the first two decades of the century, and finally came to govern U.S. energy policy in the third decade when the majority of the private sector finally put its full support behind renewables and the battle to limit global warming. All Presidents since the Obama era have supported a move away from dependence on fossil fuels – it was 80% at the turn of the century – and Congress finally placed a steadily increasing cost on carbon emissions in 2020. This created the economic environment needed for investment in clean energy technologies and reduced use of fossil fuels. It allowed the U.S. to finally catch up with the many other countries that had seen the importance of these changes and implemented appropriate policies many years before.

These changes have led to today’s energy situation in the U.S. – 70% of electricity is generated by solar, wind, hydropower, and geothermal, natural gas from fracking peaked in 2040 and is steadily being replaced as an energy source in power plants as renewables take over, petroleum from fracking of oil shale peaked at about the same time and has been used to power aging and disappearing transportation fleets, electric vehicles dominate the automobile and light duty truck markets, all new aircraft and ships are designed to run on alternative biofuels, energy efficiency has been enshrined as the cornerstone of national energy policy, coal has been replaced as a domestic energy source except in a few industries, and nuclear power’s share of electricity generation has been steadily reduced to its current value of 5%. Total national energy demand has been stable even as the U.S. population has increased to 400 million, all new homes are routinely outfitted with solar energy rooftop systems and ground source heart pumps wherever feasible, the U.S. leads the world in wind turbine and wind energy production, we are second only to China in offshore wind energy deployment and production, and battery energy storage has become as ubiquitous as any other household appliance.

The world has turned a corner in these pat 50 years, undergoing an inevitable transition to dependence on energy from the sun and heat derived from radioactive decay in the core of the earth. These clean energy sources will last as long as people populate the earth, unlike fossil fuels which are depletable on any timescale relevant to humankind. We owe much to our fossil fuel resources, the product of millions of years of transformation of organic materials subject to high temperatures and extreme pressures deep in the earth, but the fossil fuel era is coming to an end and will eventually be only a blip on the timeline of history.

My promise to you as your President will be to continue and strengthen this transition in all ways possible so that our children, grandchildren, and their heirs, will live in a world free of global warming and the other harmful impacts of burning fossil fuels. Nuclear fission power had its day as well, but the issues associated with its use – cost, safety, long term storage of wastes, and weapons proliferation – have proved too difficult to accept now that renewable energy has been shown up to the task of meeting societal needs. Nuclear fusion, a much cleaner form of nuclear energy, remains as a long term possibility as well, but progress in taming the process that powers our sun and other stars has been slow and time will tell if controlled nuclear fusion has a future here on earth. I support continued cooperation with other countries in researching this technology that offers unlimited energy availability but so far has always been a few years away. Our investments largely must go into renewable technologies to ensure completion of the transition. This is our legacy to the future.

The Coal Conundrum

A long article in the October 16th Washington Post, ‘U.S. exports emissions – as coal’ by Joby Warrick, points out the conundrum posed by the U.S.’s abundant coal resources. These coal reserves provide a relatively low cost energy resource that can be burned to produce steam and electricity and improve human welfare in both the U.S. and other countries. However, its combustion produces large amounts of carbon dioxide that when added to the atmosphere causes global warming and associated global climate change. The conundrum arises from a clear conflict of values – the need to provide energy services to people around the world, in particular people in developing countries whose per capita consumption of electricity is well below that of developed countries, and the need to address climate change with its many adverse consequences, identified by many as the most serious problem facing the globe. No easy answer exists to satisfy those on both sides of this conundrum.

Several statements in Warrick’s well-researched article captured my attention, including: “Just a dozen nearby mines, scattered across a valley known as the Powder River Basin (Wyoming), contain enough coal to meet the country’s electricity needs for decades. But burning all of it would release more than 450 billion tons of carbon dioxide into the atmosphere – more than all greenhouse-gas emissions from all sources since 2000.” and “The Obama Administration is seeking to curb the United States’ appetite for the basin’s coal, which scientists say must remain mostly in the ground to prevent a disastrous warming of the planet. Yet each year, nearly half a billion tons of this U.S.-owned fuel are hauled from the region’s vast strip mines and millions of tons are shipped overseas for other countries to burn.”

Given the legitimate needs on both sides of this conundrum I can see only one path to follow to bring the benefits of electricity to as many people as possible while minimizing the risks associated with burning coal. This is to promote the use of energy efficiency technologies wherever feasible, to reduce the demand for coal-based electricity, and expedite the development and deployment of renewable electric technologies such as solar and wind as substitutes for coal. This is already happening to some extent as the world slowly begins to come to grips with the climate change problem, but the pace needs to and can be accelerated. The ability of renewables to meet most of the world’s electricity needs has been documented in several recent studies, e.g., the June 2012 NREL report entitled ‘Renewable Electricity Futures Study’, and what is now needed is a commitment on the part of national governments and international institutions to make it happen as quickly as possible. It is a matter not of technology but of political will and financial resources. Admittedly, such a switch from coal and other fossil fuels (natural gas, oil) that also produce carbon dioxide when combusted, to a renewables-based energy economy, will take time, lots af planning, and lots of money. However, when the full costs of using fossil fuels are taken into consideration, including not just market costs but also health and climate change-related costs (such as coastline flooding due to rising seas, changed precipition patterns that adversely impact water availability and agricultural production), and international tensions due to competition for fossil fuel resources, renewables become a much more attractive and even less expensive long-term option. Renewable resources are also insensitive to cost increases once initial capital investments are made, unlike fossil fuels that rely on a depletable resource that produces uncertain and often volatile costs.

Nuclear power advocates will make some of the same arguments since the process of releasing energy via nuclear fission does not produce greenhouse gases, but nuclear technology faces four serious problems: high cost, safety, the need for long-term radioactive waste storage, and proliferation of weapons capability. If these problems can be successfully addressed, then nuclear-powered electricity can be a viable option for the future. Nuclear power also offers the tantalizing option of nuclear fusion, a relatively safer and cleaner nuclear technology with enormous resource potential, but the problem of achieving controlled nuclear fusion on earth (it is the process that powers our sun) is proving to be the most difficult technological challenge the world has faced to date. It can legitimately be labeled ‘the technology that is always a few years away.’

In sum, the choice is ours – we can continue to use our coal resources without limit or we can move more quickly to a clean energy society that provides needed energy services and minimizes global warming and climate change effects. I vote for the latter.

Returning to an Important Subject: the Vulnerability of the U.S. Electrical Grid

I’ve just had an amazing experience – I listened for about an hour to an online advertisement for an investment newsletter. You may reasonably ask why would any compos mentis individual devote an hour of their life to an advertisement for a service that he was unlikely to sign up for? My answer is simple – the ad addresses an important issue that I have touched upon in earlier blog posts, and in accurate terms once you sift the wheat from the chaff of a much too long presentation. It also presents a worst case scenario to get your attention, a common advertising technique, but it also presents information on what I consider a significant national security risk – the vulnerability of our national electrical grid system to natural or malevolent events. The ad, in its infuriating stretched-out discussion, addresses this vulnerability from four sources – sabotage, solar flares, cyber attacks, and military attacks. The ad’s discussion includes references to federal government and NARUC (National Aassociation of Regulatory Utility Commissioners) reports that address Black Sky Day possibilities and which are easily accessed. Black Sky Days are defined as “extraordinary and hazardous catastrophes utterly unlike the blue sky days during which utilities usually operate.”

My concern about the grid vulnerability issue goes back about thirty years and has only grown with time. I truly believe we are a highly vulnerable society and are not yet paying enough attention to our vulnerabilities. I hope I am wrong.

In any event, I present the link to the ad below (I wish it had an Executive Summary) and to my two previous blog posts that discuss the vulnerability issue. We need more attention to these perhaps unlikely events but ones with potentially massive consequences.
