If I told you that I had created a process to extract pure gold from seawater, you might deem it an amazing accomplishment. If I issued a press release stating these facts, it very well could go viral.
In fact, the oceans do contain an estimated 20 million tons of dissolved gold, worth close to a quadrillion dollars at the current spot market price. But you may have noticed that I have omitted a very important fact.
I haven’t mentioned how much it costs to produce a troy ounce of gold using the process I have designed. That seems like an important detail, so I explain that the production cost is only $50,000 or so per ounce (which today is worth about $1,265), but I am sure that with enough investment dollars — and maybe a few government subsidies — I can get that cost down to something more reasonable. (This is how we subsidize some advanced biofuels where production costs are an order of magnitude above what could be considered economical). CONTINUE»
Each year in June two very important reports are released that provide a comprehensive view of the global energy markets. The highlight of the recently-released Renewables 2016 Global Status Report (GSR) was that the world’s renewable energy production has never been higher. But the biggest takeaway from this year’s newly-released BP Statistical Review may be that the world’s fossil fuel consumption has also never been higher.
Demand for crude oil set a new all time-high in 2015. Despite all the hype about electric vehicles and peak oil demand, the world’s oil demand continues to grow unabated — growing a robust 1.9 million barrels per day (bpd) from 2014 (+1.9% year-over-year).

Andrew Revkin posted an interesting article a few weeks back:
Lately, I’ve come to frame the challenge as a question: Can we foster an online (and real-life) culture in which veracity is cool? You’ll see more on this here in the coming months.
As social primates, we are instinctively motivated to seek higher status in our given troop hierarchies. The word cool is sometimes used as a synonym for impressive. Impressive denotes a measure of status. Coolness is any marketer’s primary weapon. I like Andy’s idea of making veracity cool, but I’m skeptical it could ever take hold. How would car marketers ever convince us to buy their cars? Although, certainly, he’s on the right track in that, if you want to change behavior, like getting people to drive electric cars (or Hummers), convincing them it’s cool to drive one will work wonders.

In my previous article — Leonardo DiCaprio’s Huge Carbon Footprint — I discussed the seeming inconsistency of Leonardo DiCaprio’s climate change activism and his excessive fossil fuel consumption. My argument was that with his own large carbon footprint, DiCaprio is undermining his message and making himself an easy target for critics.
My argument wasn’t specifically that he is a hypocrite, although that has indeed been the argument of many. But others have argued that DiCaprio isn’t a hypocrite at all, because he isn’t actually asking anyone to sacrifice. This is the position articulated well by David Roberts at Vox in Rich climate activist Leonardo DiCaprio lives a carbon-intensive lifestyle, and that’s (mostly) fine. I generally find a lot of truth in what David writes, even when I disagree with him. But here I kind of think David misses the point.
Roberts acknowledges the appeal of the critiques against DiCaprio, noting that there are even plenty of liberals and environmentalists who are quick to criticize climate activists with high-carbon lifestyles. He believes there are two arguments that DiCaprio’s critics make, and then he sets out to debunk them. My intention today is to challenge his debunking. CONTINUE»
Leonardo DiCaprio recently won the Oscar for Best Actor for his performance in The Revenant. I saw the movie, and to my layman’s eye it certainly seemed like an Oscar-worthy performance. I was rooting for him to win, as was, it seems, most of America. His victory reportedly set a social-media record, with 440,000 posts in about a minute to become the single-most Tweeted minute during an Oscar telecast.
While I applauded his victory, I took exception to part of his acceptance speech. Here is an excerpt:
“Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating. We need to support leaders around the world who do not speak for the big polluters, but who speak for all of humanity, for the indigenous people of the world, for the billions and billions of underprivileged people out there who would be most affected by this.”
The problem isn’t the message. I believe we are engaging in a dangerous experiment by dumping ever-increasing amounts of carbon dioxide into the atmosphere. I don’t think there is an easy fix to the problem, but I agree with his characterization that it is an urgent threat. CONTINUE»
My previous article was about Bill Nye’s choice to ignore the science when it comes to nuclear energy safety. I’m not picking on Bill. My critiques are in response to Nye’s decision to use his celebrity status to publicly air his anti-nuclear energy beliefs. This is likely the last article I’ll write about his views …depending I suppose, on what else he has to say in public about nuclear energy.
As I have done for several years now, I like to close out the year by highlighting the top stories in the energy sector.
The 2015 list was challenging, because so many of the stories are interrelated. Commodity prices continued to plummet, but oil, natural gas, and coal prices fell for somewhat different reasons. This of course resulted in the lowest gasoline prices in years, which was itself a big story.
A crude oil export ban that I believed would stick around for years was repealed, yet it’s part of a spending bill that also extended tax credits for renewable energy. So is the story the spending bill, or its particular provisions? These were the challenges I had to sort out.
The rankings are somewhat arbitrary. This year there wasn’t an energy news event as dramatic as the Deepwater Horizon oil spill of 2010, or the Fukushima Daiichi nuclear disaster of 2011. Here is the list I settled on. CONTINUE»
With world leaders meeting in Paris this week and next to formulate plans for tackling carbon emissions, I believe it’s critical to understand the source of those emissions. After all, if you are going to solve a problem, you better make sure you have a good understanding of the problem. Otherwise, as the great philosopher Yogi Berra might say, your solution to the problem won’t necessarily solve the problem.
In today’s column, I want to cover three items. First is the present and past geographical breakdown of carbon dioxide emissions. Second is the breakdown by type of fossil fuel. Third is the breakdown of potential future emissions given the world’s current oil, gas, and coal resources.
The Current Geographical Emissions Profile
In my previous article, I showed that the world’s carbon dioxide emissions had historically come from the world’s developed countries (as defined by membership in the Organization for Economic Co-operation and Development), but since 2005 emissions in developing countries have outstripped those in developed countries. Of the 35.5 billion metric tons of carbon dioxide emitted in 2014, developing countries were responsible for 21.7 billion tons — 61% of the total: CONTINUE»
Energy on the Edge
Along with the OPEC meeting that takes place late this week, the biggest story in the world of energy is the Paris Climate Change Conference (Conference of Parties 21, or COP21) that runs through the end of next week. This conference is put on by the United Nations with the goal of producing a global agreement that will lead to a reduction in greenhouse gas emissions. Implementation of strategies that will help mitigate potential impacts of climate change are also on the agenda.
Decarbonizing our energy systems by encouraging greater usage of alternative energy — a frequent topic of this column — is one of the common themes in the fight against rising greenhouse gas emissions. Next weekend a new episode of National Geographic Channel’s Breakthrough series covers progress being made on this front. “Breakthrough: Energy on the Edge” debuts Sunday, December 6, at 9 pm ET on National Geographic Channel and covers some of the latest advances in alternative energy.
Ahead of the premiere, National Geographic Channel contacted me and extended an invitation to join the conversation by answering the question “Do you think that by tapping into the new alternative energy sources we can reverse most of the damage we have done to our environment?” But first I think we need to step back and make sure we understand the problem. Failure to correctly characterize a problem makes it much more difficult to address that problem. So let me first offer some context on the question. CONTINUE»
A Long-Awaited Decision
Earlier this month, after a debate that spanned nearly the entire duration of his presidency, President Obama finally rejected the proposed Keystone XL pipeline project. He had been heavily criticized on this issue from many angles, including by me, for his long-running failure to make a decision on this issue. For the record, my position on the pipeline wasn’t that it should be built. Nor that it shouldn’t. But rather that it was a distraction that garnered far more attention than it deserved, while more important issues desperately warranted attention.
Today, in the last Keystone XL article that I plan to write, I want to review the controversy, explain why I feel it took on a symbolic meaning far beyond what it deserved, and describe some of the other things that were taking place while an environmental movement mobilized to stop the pipeline. In a nutshell, I am going to strip the symbolism and wishful thinking and address things we actually know to be true. CONTINUE»
