Weird Wyoming

Along with having the entire atmosphere pass through the state in any 24 hour period, Wyoming has some other attributes beside the wind.  I like Wyoming for its diversity and the fact it doesn’t have too many people.  The diversity also extends to the geology. Prairie in the east, Devil’s Tower and the beautiful country around there to some of the most spectacular alpine country anywhere, even if the mountains are lower than ours in Colorado.  Oh, and Yellowstone, our first National Park.

Wyoming Geology

I especially like the deserts, like the Great Divide Basin, aka the Red Desert, a depression rimmed by the Continental Divide.   Yellowstone is the largest and most dangerous volcano in the country.  There is coal, iron ore, oil and gas, uranium, and trona, to name a few.  Those resources are a double edged sword, leading to a boom and bust economy.  Ranching just soldiers along,  but it is a hard way to make a living.

A good portion of the economy comes from Greens (Coloradans, known for their green license plates).  It’s the topography that draws me.  Rivers flowing north, through mountain ranges, fed by hot springs.  A range of hills known as the gas hills, where methane comes out of the ground.  Mountain ranges running north and south as God intended, but the Snowy Range runs east-west and is the boundary between the ancient island arcs known as Colorado and the much more ancient Wyoming Craton.

The Wyoming Craton has some of the oldest rocks in North America, sharing the antiquity with the Canadian Shield.  Ages vary but are around 2.6 to 2.8 billion years old.  The oldest rocks in Colorado are around 1.7 billion years old and arrived as an island arc smashing into Wyoming, much as Indonesia and the Philippines are headed to Asia.

Wyoming has had a lot of activity down deep, shoving mountains up and sliding them around.  That pushing and shoving means areas where oil and gas get concentrated in the bends and corners, thus all the oil patch work there.  There is a lot of coal. The Union Pacific got its coal right near the tracks, and there is a tremendous amount of coal in the Powder River basin.  Coal is out of favor now, so Gillette is hurting, people leaving.

The reason Wyoming got famous is for two reasons, unruly Indians and the livestock business.  There was a lot of Indian fighting in the middle of the nineteenth century, what with the Oregon Trail crossing the region.  When the Indians were whipped, all that empty country became home to cattle and sheep.  The livestock people still hold most of the political power – they also have oil and gas leases, so they aren’t very environment friendly.  Lots of cowboy legends came out of the place.

My favorite things are the rivers running through mountain ranges.  The textbook example are the Wind and Bighorn rivers.  They got their names because early explorers didn’t realize they are the same stream bisected by the Hot Springs Mountains.  The Bighorn flows south through Thermopolis and its hot springs and roses into a beautiful narrow canyon.  The Wind River flows out of the canyon.  The river was there, the mountains came up, and the river (rivers?) stayed in the same place, cutting the canyon as the uplift occurred.

Do I need to say the Wind River is aptly named?  Years ago in Colorado Springs I met a bicyclist doing a ride across the country.  He came across Wyoming.  He looked at me and in awe said,  “The Wind”.  He rode into the wind all across the state.  Another time I was driving from Laramie to Fort Collins after dark. It was Christmas time and the ground blizzard was in full song. I saw a VW bus along the road near Tie Siding. In conditions like that, you stop.  The occupant was from Australia and said “I’ve never encountered weather like this.”  It was around zero with 50 mph wind.  The VW had quit, probably a frozen gas line, and his wife got a ride into town to get help.  Shock and awe.  I just laughed and saw he was OK.  You know about the Wyoming Wind Gauge.  It’s a length of heavy chain hanging from a post.

Climate Change

Florida Flooding

Florida Flooding

Here it is, the last day of November, and we still have some tomatoes from our garden.  We had the hard freeze a couple of weeks ago, but we brought quite a few in before it froze.  This fall has been the fall of pasta sauce and tomato soup.  Traditionally the first freeze is in September or early October.  Not this year.  Now, just because we have one warm fall doesn’t necessarily mean global warming, it is a matter of relatively long term trends.  That is happening, folks.   

Worldwide, it is about one degree Celsius and climbing.  The culprit is carbon.  We need carbon, our bodies are mostly water, but carbon hangs everything together.  Florida, for example, is mostly calcium carbonate, limestone.  The limestone formed even the peninsula was underwater with a climate encouraging the growth of untold billions of tiny organisms with calcium carbonate shells.  They die, and if whales don’t eat them, their shells sink to the sea floor.  Well, even if they do get eaten, the whale turds are calcareous.   

Porous Limestone

Porous Limestone

Millions of years and sea level change, and Florida emerges.  The cycle doesn’t end there.  It rains on Florida, and the slightly acidic rain starts dissolving the limestone, sending the carbonates back to the sea.  Enough of the limestone has dissolved to make the peninsula a honeycomb.  Sinkholes, underground rivers, high tides bringing ocean water inland and flooding streets in  Broward county.  The southern part of the state is headed back underwater.   The really big deal is that sea level is rising.   

I have given an example of the carbonate cycle, which is going on worldwide.  The other cycle going on is the water cycle.  Our planet is delicately balanced in temperature around the freezing point of water.  The water evaporates, and if it is cool enough, some of it falls as snow and accumulates, mostly in the polar regions.  At times the ice forming from all that snow has made it as far as Central Park in New York,  that is a lot of water tied up on land.  Sea level drops, and Florida emerges.  

Currently, the cycle is going the opposite direction.  The ice is melting, and the process seems to be accelerating.  Why?  Carbon.  Here in Denver, I see huge coal trains hauling coal south to be burned to run air conditioners in Texas.  The coal, carbon, is ripped from the ground where it has lain for millions of years, mostly dead plant life converted into coal.  It is burned, sending carbon into the atmosphere.  I drove here to the coffee shop burning gasoline, which comes from oil made deep underground from what once were living organisms.  The carbon goes into the air, the climate changes due to human activity.  We are in a new epoch, the Anthropocene.

Elemental carbon is fairly rare.  Diamonds, graphite.  Carbon likes to combine with other stuff to make, well, us and other living things.  That carbon gets sequestered in the earth, reducing the amount of carbon available to make new stuff.  There is a cyclical balance, dependent on worldwide temperature and, lately, us.  We burn carbon based fuels and the carbon dioxide goes into the atmosphere.   

The sun shines, warming everything up.  A lot of that heat gets radiated back into space, maintaining a balance favorable to life.  When that radiant heat meets a CO2 molecule, it warms the molecule.  More carbon, more heat in the atmosphere.  That’s greenhouse gas doing its thing.  The global climate warms up, making some regions wetter, some more dry.  We have gotten used to having a relatively stable climate, and we adapt to it in many ways.   

When the rain and snow fall changes, our adaptations stop working so well.  This is especially important in coastal regions, because all that polar ice starts melting and sea level rises.  Most of the population lives near the coast.  With the coasts moving inland, the people and all their stuff will have to move as well.  Battery Park at the southern tip of Manhattan gets flooded in big storms.  The subway tunnels flood, and people have trouble getting around.  The time is coming when they will be living in central New Jersey.  The horror. 

There are lots of people denying all this, saying it is just the normal weather cycle.  That is true, but it is a new normal, and is changing.   What to do? Stop putting so much carbon into the air and start putting it back into the earth.   That means big change in the way we do things, and those getting rich on the status quo don’t want their businesses upset.   Oil and coal, mostly, but they drive all of our economy.  So, they say it isn’t so, and let’s burn, burn, burn.   

What goes around comes around.  It is just a matter of time.

More on Discontent

The Age of Steam

The Age of Steam

Our economy has been one of change since the beginning.  When the railroads came to Colorado in 1870, a lot of teamster jobs hauling freight from Omaha and Kansas City went away.  The automobile would not have happened without the new petroleum industry.  Coal retained its strength from powering locomotives, heating homes, and fueling industry.  Industry and manufacturing grew, making the American economy one of the largest in the world.

What a combination, land, natural resources, transportation, a growing population of people with ambition, mobility, and a willingness to try something new.  Some were left behind.  Native Americans, African Americans, and those new citizens in the Southwest who were once part of Mexico with its traditional ways.  As always, immigrants ended up at the bottom because of language and discrimination.

There were troubles.  Low wages, a turbulent labor history, drought, an unstable business cycle creating panics individuals were helpless to influence.  There were some adventures the government engaged in, such as Cuba, the Philippines China, Japan, all the trappings of empire.  In many ways the American West was an empire, won at the expense of those who were living there.

Agriculture was becoming more mechanized, displacing people who moved to the cities to work in industry.  All the change continues.  There is a tremendous amount of wealth in Silicon Valley, not so much in Michigan.

The West has been boom-bust from the start.  The fur trade collapsed, but the gold rushes started.  The government started giving land to the railroads and individuals.  The short grass prairie boomed with hopeful wheat growers, then the droughts came.  Oil and gas grew and grew, and grew.  As old fields played out, new oil fields were discovered.  A couple of big wars really heated things up.

It all looked great.  Yes, lots of change, but people could find good jobs and things steamed along.  The real upheavals were when the business cycle threw millions out of work.  The 1930’s were a terrible time, but a war healed all that.

The West That Never Existed

The West That Never Existed

The 1950’s seemed like a golden age.  Lots of jobs, the U.S. Ruled much of the world, and television built a myth of stability, prosperity, and a bright future for everyone.  the myth came from relative prosperity and the ubitiquous westerns on television promoting a life that never existed.

The 1960’s brought social upheaval accompanied by a growing shift in how people made their living.  Steel mills closed, imported cars were on the roads, and computer-driven automation started taking industrial jobs.  The word Yuppie became a term of derision, but the Yuppies were the wave of the future.  They possessed education and a skill set many people could or would not obtain.

The skilled trades fell out of favor. It is college or else.  The trade jobs are filled the way they have always been filled, by immigrants.  This time however, the immigrants are not easily assimilated Europeans.  They are Latin, and and bring their culture with them.  Many are just not as interested in assimilating, and many are undocumented.

All this change leaves a huge segment of our society out of the good life.  Many are rural, where big mechanized farms haven taken jobs.  Many just do not have social and intellectual requirements to move into the new economy.  What’s left?  Low-paying service economy jobs, often for an out of date minimum wage inadequate for one person, let alone a family.  It is hard to build a life mowing lawns and doing kitchen work.  Much of the time jobs that used to be stepping stones have turned into dead ends.

The trouble is just beginning.  Those people marginalized by an economy where they don’t fit can be radicalized and turn to violence and terror or Donald Trump, which may be same thing.  The discontent is just not with the marginalized working class.  There are lots of well-educated people from middle class families making pizzas and living in their parents’ basement.  They thought they were doing the right thing going into debt to get an education and found nobody wants them.

This is still a rich country.  There is a huge imbalance in the distribution of wealth which has to change.  The change agent must be government.  A true progressive tax structure and an end to the massive influence of special interests in government are desperately needed.  The nation has the resources to provide everyone with an income providing them some dignity and the flexibility to enhance their station in life.  Given a decent income, most will seek ways to do even better.

We will always have the wealthy and the poor.  Now, there is too much concentrated wealth for a few and too many poor.  Trying to revert to an American utopia which never existed will only add to social instability.

Happy Days Are Here Again

Happy Days Are Here Again

There should be no food banks or coat drives.  There should be no one sleeping on the streets.  People with mental health problems should not be cast out.  Everyone should have the time and resources available to build better lives for themselves rather than being trapped in poverty.

In other words, we need a new time of progressive change, not an attempt to return to a myth.  How to pay for it all?  A realistic progressive tax system to redistribute income.

King Coal’s Crown is Slipping

Idle Coal Car

Idle Coal Car

Recently I have done a couple of road trips where I paralleled abandoned or seldom used railroads.  On one trip I came down the Arkansas from Salida to Pueblo, years ago the main line of the Denver and Rio Grande Railroad.  The other route was from Alamosa to Walsenburg, the route of the Rio Grande to the San Luis Valley and on to Gunnison over Marshall Pass.   

On both trips the lower portion of the railroad grade had literally miles of parked gondolas, or coal cars.  The gondolas on the Arkansas were the old-fashioned steel cars.  Those cars are replaced by mostly aluminum cars which are significantly lighter.  The railroads make more money hauling coal instead of heavy steel cars.  Dropping down to Walsenburg were miles of the more modern aluminum cars holding air rather than coal. 

The railroads have lost a huge amount of coal hauling business.  All over the country, coal mines are shutting down, the coal replaced by cheaper natural gas.  Not all the coal trains are gone, I saw one yesterday on its way south through Denver.   

Colorado Springs Power Plant With Idle Coal Cars

Colorado Springs Power Plant With Idle Coal Cars

Colorado Springs has a socialist Utilities Department, generating power and delivering natural gas along with the traditional water and wastewater systems. The big power plant south of the city used to burn so much coal the city bought its own coal train.  All those cars are idle, sitting at the power plant.  Now, it is natural gas powering the generators. 

Colorado has a colorful coal mining history.  The Colorado Fuel and Iron steel mill in Pueblo got its coal from mines just west of Trinidad.  That region had lots of mines accompanied by lots of labor trouble around the turn of the twentieth century.  There were mines in Colorado Springs, west of Denver, a big industry around Louisville and Lafayette.  The mines at Somerset, just north of Paonia are in the process of shutting down.  Craig and Hayden are in trouble, and the mines in the Grand Junction region are long gone. 

“Clean Coal”, a big lie if there ever was one, is on its way out.  Peabody Energy is bankrupt, along with many other mine operators.  We will have coal’s legacy for a long time.  Climate change, fouled rivers and air, areas mutilated by strip mining, and huge piles of mine waste are our children’s inheritance.   

wind_energyAlternative energy, including solar power and wind generation are part of the equation, but cheap and more clean burning natural gas is the main reason for the change.  Gas is cleaner than coal, but it still puts huge amounts of carbon into the atmosphere.  It is just another fossil fuel.  The fossil fuels sequestered huge amounts of carbon that otherwise would contribute to global warming.  Now we are burning all that carbon and heating up the planet. 

Gas is better, but still bad.  All that cheap cleaner burning gas may even slow the transition to renewable energy sources.  On balance, however, we are better off with gas than coal. 

Where is all that cheap gas coming from?  There has been a major technological advance in the oil and gas industry.  The advance is horizontal drilling.  In past years, one hole went into the ground and the oil and gas was extracted froze around that single hole.  The amount recovered was highly dependent on the porosity of the rock formation holding the oil and gas.   

Hydraulic fracturing (fracking), developed in the 1950’s expanded the amount removed from less porous strata, but not on a huge scale.  To get more out of any field with tight rock required lots of expensive drill holes.

The big change was the development of horizontal drilling.  The process took years of development, but now slant drilling is cost effective and allows hydraulic fracturing over a much wider area compared to down hole drilling.  Fracking the slanted holes allows gas and oil to be extracted from oil and gas bearing shales formerly not economically feasible. 

There is much opposition to fracking because the technology allows drilling in new areas where the population is not used to a dirty industry in their back yards.  Traditionally, the industry did not pay much attention to leaking wells.  There was little regulation, and all that stuff went into the atmosphere.  The oil fields in the Four Corners region are the source of the highest atmospheric methane readings in the country.  

Leaks are common because it costs money to prevent them, lowering profits.  The leaks can be prevented, it just takes more work and money.  The big blowout in the Gulf shows that oil companies tend to cheat when the dangerous practices are taking place where no one can see them.  On-site regulation can stop the cheating and oil and gas production from horizontal drilling and fracking can continue safely. 

The downside is the clear need to eliminate our dependency on fossil fuels.  We need to remove carbon from the atmosphere, not increase the amount.  Until more alternative sources come on line, natural gas is preferable to coal, and King Coal can be deposed.  The current difficulty in making the transition is political, with the extractive industries resisting the change at every step.  They are spending money to delay the changes that could be used to make change, not enrich politicians and the advertising industry. 

Residential Solar Power

We have solar panels on our house and garage.  Out utility bill this month will be less than twenty dollars.  Xcel Energy is attempting to eliminate the incentives for home solar power so they can continue to produce power using natural gas.  It’s political, folks.

Carol and I are concentrating on how we use energy.  Watching “Cosmos” with Neil DeGrasse Tyson pointing to the sun and saying, “It’s Free!” is partly responsible.  I did a lot of research for my talk on Front Range Colorado flooding.  One conclusion I reached is that the climate change we are now experiencing will lead to more floods.

Releasing fossil carbon into the atmosphere is setting up a worldwide crisis of unparalleled magnitude.  Drought, wildfires, floods, sea level rise, and pollution will affect millions worldwide.  The environmental changes have already increased political instability. Syria and sub-Saharan Africa are cases in point.

Here in the U.S., rhetoric and denial are the most visible response to the looming disasters.  Those who make money from fossil energy deny the problem and buy inaction in Congress.  Public utilities seem to be much more interested in selling gas and power produced from coal and gas than switching to renewables.  Wind farms are on the increase and more commercial solar power installations are being built, but the pace is fairly slow.

Germany is a leader in switching to renewables, but recent stories that over 70 percent of production is from renewables is exaggerated.  The fact is that their wind and solar production is increasing, while coal use is declining.  China is starting to move to renewables, but is the world leader in coal use, and coal production is increasing.  In China, 66% of their power comes from coal compared to 49% in the U.S.  The switch to gas from coal is on, driven by cheaper gas (from fracking) and the high cost of coal plant pollution controls.  Burning gas has about half the carbon footprint of coal, but it is still burning huge amounts of carbon sequestered millions of years ago.

Worldwide people and governments are starting to respond to the dangers of fossil fuel generated climate change, but slowly.  So what are we to do?  Join the grassroots green energy movement.  People use all this energy, so people have to use less.  Less gasoline, less natural gas, less electricity, and most of all, less coal.

So what is a couple from Denver to do?  We aren’t much for marching in the streets or being rabid environmentalists, but we want to do our part.  Activism begins at home.  In our case, home is a brick bungalow built in 1937, when builders were not concerned with energy efficiency.  The main thing builders did in the 1930’s did was build smaller houses.  Ours has 830 square feet on the main floor.  It is a far cry from the 2400 square foot houses that are today’s norm.

We did add a 400 square foot sunroom that we can close off from the rest of the house.  In the winter, it is at 40 degrees, and an exhaust fan pulls cool air from the basement in summer.  We have a modern high efficiency furnace and water heater.  We have increased the attic insulation twice, first to R36, then to R50.  The original steel casement windows are terrible for leaking cold air in winter, and hot air in summer.  We have historical designation on the house which means keeping those windows, but we installed inside storm windows that stop those wintry breezes.

Carol forces me to tolerate 68 degrees in winter and 78 degrees in summer.  That mainly means either more or less clothes depending on the season.  At night the programmable thermostat is set for 56 degrees, but the house seldom cools off that much.  I did break down and get some fleece lined slippers instead of my beloved L.L. Bean moccasins.  The basement, with my man cave, gets cold.  I guiltily run an electric heater.  Someday we will insulate those cold basement walls.

When we increased the attic insulation the first time we also put in attic ventilation.  We had rooftop vents installed and put a large vent in the north gable to introduce cooler outside air.  When we re-roof we will add more vents.  Prior to that, the only ventilation was a small vent over the entryway.  It sure did get hot up there.

The air conditioner has a device provided by our electric utility that runs it less often during periods of high demand for power on hot days.  To reduce air conditioner use we open the house up in the evening and run fans to exhaust hot air and bring in cooler outside air.  Denver averages a thirty degree difference between daytime and nighttime temperatures.  Texans, eat your hearts out.  When we have to have a new roof in the next few years we will add an attic fan.  They are noisy, but they exhaust hot air in the house and cool the attic.

The big thing we are doing now is adding solar electricity with our new garage.  We have needed a garage for some time.  We have never been able to park a car in the old one, designed for a 1937 Ford.  My shop area, the gardening stuff, until recently my motorcycle, and the bicycles filled it up.  Our block has an alley, which is a crime conduit.  We have had several break-ins, and want our cars inside.

The solar panels will go on the garage and sunroom roofs.  When we replace the roof on the older part of the house, we will add enough panels to produce all the power we need.  We will be at about 80% with the house and sunroom panels.

So we are slowly going green.  It is possible for individuals to make a difference.  If more of us do it, it will pressure governments and the utility companies to get serious about energy.  It will take grass roots action to make it happen.  Boulder, Colorado is threatening to take over Xcel energy’s infrastructure in their city.  That is a message to the utility companies that they have to get serious about renewable energy or lose their customers city by city.  I am hopeful that meaningful change is going to happen.  I don’t think it is enough to stop some of the climate changes we are seeing, but we are slowly starting to try living with our planet, not exploit it to our extinction.

More on Fracking and Clean Coal

Some good news and bad news in the energy business.

Colorado Governor John Hickenlooper promulgated new regulations that should go a long ways toward ending pollution from oil and gas wells.  Each well will have monitoring equipment that can detect any emissions from the well Here is a link.

The bad news, Duke Energy has a lot of coal ash ponds in the southeast, and one collapsed into the river.  Duke is a powerful lobbyist, and has successfully avoided any strict regulation or penalties up to this point.  This event may change that.

i am struck by the corporate attitude to these harmful and costly events.  Lobbyists are paid, campaigns are funded, lots of false rhetoric is expended fighting regulatory oversight of mining, drilling, and processing operations.  “Regulations and government intrusion kills jobs.”  So little regulation goes into place until a hugely expensive disaster occurs, with cleanup costs far exceeding the costs to do the job right.

i think fighting regulation is due to the constant corporate pressure to have a good quarterly profit.  Expenses that cut into short-term profit are avoided by managers who avoid or never see reports from the field warning of potential environmental problems.

In my experience, weak managers who lack foresight and the ability to sell needed projects to the higher-ups tend to focus on cost cutting.  Tanks leak, ash retention ponds fail, and faulty blowout preventers fail, all in the name of quarterly profits.

Last quarter’s numbers look good, but the overall profit picture is not so good for Freedom Industries, Duke Energy, or BP Petroleum.

My favorite case in point is when Freon was banned due to ozone layer damage.  The refrigeration industry fought the change until they realized that they were the ones to do the work replacing Freon.

Rather than killing jobs, environmental regulation created jobs and benefited everyone, and the consumer paid the cost, fair enough for having a cool house and car.

 

Coal Ash 2

Coal Ash Spill

Clean Coal

 coal-smoke-stacksAfter WWII, a lot of research was done examining propaganda techniques.  The impetus was how Nazi propaganda was used to control the German people.  A major technique is The Big Lie:  take an obvious falsehood, such as the international Jewish Conspiracy, and repeat it so often that the citizens start believing in it.
A current Big Lie here is Clean Coal.  Take a look at a coal train, coal mine, or coal fired power plant and you can see that coal is not clean.  Yes, coal is somewhat cleaner than in past years, but the evidence is overwhelming that coal is our dirtiest energy source.
I am from Western Colorado, and my father liked to tell stories about the coal smoke cloud over Grand Junction in the days when coal was used to heat most houses and businesses.
In Colorado, most power plants have converted from coal to cleaner natural gas.  In other areas of the country, however, natural gas supplies are tighter and gas costs more than coal.  Things have not slowed down much in Wyoming’s  Powder River Basin coal mines.  I live close to the rail lines that pass through Denver.  At any time of the day, there are several coal trains stopped waiting in line to go over the grade that is Monument Hill. Those trains are headed to Texas and other southern states
On February 10, I see a news story that the CEO of the company that spilled that coal-washing chemical in West Virginia ducked a hearing on the spill, this after they filed bankruptcy to avoid responsibility for the mess.  In West Virginia, coal is king, regardless of the consequences.  Hundreds of thousands had their drinking water made unusable for weeks.
Since the middle of the nineteenth century, there has been an ongoing battle between corporate profit-driven industries and their actions; and those who are harmed by those actions.  People harmed have turned to government for help, and the political response has made news since the first runaway horse and wagon killed someone.  Many businesses are responsible, and try their best to do no harm while making a profit.  Many other businesses, however, see profit as the goal that overrides any other concern.
Here in Colorado, the Ludlow Massacre, the most violent labor dispute in U. S. History grew out of the conditions workers were forced to endure in the Southern Colorado coal fields.  Poor pay, long hours, constant danger, and poor living conditions prevailed throughout the industry and led to a series of violent strikes in all the coal-bearing regions of the state that climaxed in Ludlow in 1914.  The governor called out the state militia to support the company owners against the strikers.  The militia attacked the makeshift tent camp the miners had built, burned it, and killed about 115 women and children.  The violence did not end.
Violence was done to the people by a combination of government and mine owners in Southern Colorado, and violence is being done to the people of West Virginia by a chemical company, part of the coal industry; and weak government regulation.  The real violence is being done to us all from the pollutants going into the air and water.
In the short run, natural gas is less damaging than coal, but the real need is to make the switch to renewable energy.  President Carter proposed a move to renewables early in his administration, even putting solar panels on the roof of the White House.  President Reagan removed the panels, cut the National Renewal Energy Laboratory by 90 percent, and the country moved backwards, accelerating the rise in global temperature and presenting us with the crisis we now face.
The U.S. Foot dragging in energy policy combined with the rapidly growing fossil energy consumption in China and India, is generating a global crisis that will only get worse before it gets better.  For us, the task is to get away from coal, then all hydrocarbons.
