There is an ongoing general discussion in the field of sustainable energy that does not carry the risk of the destruction of our current industrial society and economy about variable renewable energy.

Renewable energy includes a range of low or no carbon sources of energy – but not all renewable energy is sustainable, and not all is low or no carbon. And not all low or no carbon energy sources are from renewable energy resources.

Among the sustainable, no/low carbon renewable energy resources, the most abundant involve the harvest of variable renewable energy, with windpower and solar PV being the most notable. So one obvious strategy for a no-carbon-emitting energy system is to base it on collecting as much of these affordable variable renewables as practicable, and then use other no/low carbon sources to fill in the gaps.

However, in some quarters, this elicits a counter-argument. The most “successfully de-carbonized” economies of the world today are either those with a very high reliance on reservoir hydropower … which while very useful in the United States offers nowhere near a large enough economic resource to meet any large fraction of our current consumption … or those with a very high reliance on nuclear power.

Indeed, near the beginning of this month, Stephen Lacy briefly reported on a report from the Breakthrough Institute that raised an alarm that the new Clean Power Plan may in fact oversee a net increase in GHG emissions. The final plan does not include measures to avoid the decommissioning of substantial numbers of nuclear power plants. And the numbers are stark:

• The 30 nuclear plants at risk by 2030 avoid over 100 MMT of CO2 emissions
  
• New non-hydropower renewables are expected to avoid 60 MMT of CO2 emissions by 2030
  
• New nuclear plants under construction are expected to avoid under 30 MMT of CO2 by 2030

So where retention of those 30 nuclear power plants would find us over 80 MMT of avoided CO2 ahead, and in a position to accelerate that in the following decade … their closure could leave us over 10 MMT below where we are now.

This past Monday, the Obama administration issued the final permits allowing Shell Gulf of Mexico, Inc. to begin drilling oil wells in the Arctic. This is the same oil conglomerate that lost control of its drilling rig in December of 2012 that crashed onto the Alaskan coast in heavy seas. The disaster also lead to eight felony convictions and a $12.2 million fine

Considering President Barack Obama’s promises to focus on climate change and big speeches on controlling carbon emissions, this has to be one of his most hypocritical decisions. Compounding that hypocrisy, the president has planned a visit to the Arctic region later this month. He is the first sitting president to do so. This decision didn’t sit well with Democratic presidential candidate Hillary Clinton who expressed her opposition in tweets and at her press conference in Nevada:

I think the very grave difficulties that Shell encountered the last time they tried to do that should be a red flag for anybody. I have been to the Arctic, I have been to Barrow, our most northernmost outpost in the United States and I think we should not risk the potential catastrophes that could come about from accidents in looking for more oil in a pristine – one of the few remaining pristine regions of the world.

In a segment on her MSNBC show, Rachel Maddow blasted the president calling this decision “the most awkward and ill-timed thing he’s done in a long time”

While we should praise Secretary Clinton for this stand and her environmental platform that put an emphasis on renewable energy, she now needs to take a stand on the KeystoneXL pipeline.

Well, this is a big week in climate change what with the Pope’s encyclical due t be released Thursday, so today is gonna be climate change Monday!

First, a couple about the upcoming encyclical:

Pope Francis to Explore Climate’s Effect on World’s Poor

The first clue of the pope’s interest in the environment came when he chose his name in honor of St. Francis of Assisi, the 13th century friar who dedicated himself to the poor and is considered the patron saint of animals and the environment. Francis had shown interest from his days in Argentina, when he was Cardinal Jorge Mario Bergoglio, the archbishop of Buenos Aires.

There, he played a major role in convening different leaders to seek solutions for Argentina’s social ills. Francesca Ambrogetti, who co-wrote a biography of Francis, said he pushed for scientists at the Pontifical Catholic University of Argentina to investigate the impact of environmental issues on humanity. As far back as September 2004, Cardinal Bergoglio cited the “destruction of the environment” as contributing to inequality and the need for social reforms. At a 2007 meeting of Latin American bishops in Aparecida, Brazil, he oversaw the drafting of a broad mission statement that included an emphasis on the environment.

Pablo Canziani, an atmospheric physicist who researches climate change, said Francis, who had once trained as a chemist, became very interested in the links between environmental destruction and social ills, including a dispute over paper pulp mills on the border with Uruguay, which Argentina claimed were polluting local drinking water.
