Melomys Rubicola has been declared extinct. Had it been something like a fuzzy koala or panda instead of a rat, the world might have taken more notice, but maybe not. A Google search on the topic goes over 20 pages deep. This seems to have struck a nerve.
It’s possible that an undiscovered genetically identical population exists somewhere else. It’s not unheard of for a species declared extinct to show up again. But if it has been on that tiny island off the coast of Papua New Guinea long enough for speciation to occur, then it is extinct because to repopulate someplace else a pregnant female would have needed to leave the island and establish itself elsewhere, and that is extremely unlikely.
There have been some dubious claims of extinctions caused by climate change, as one would expect, and I’m sure there will be many more. But little by little, the real extinctions will arrive. 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).
Contrary to what you read in the lay press, nuclear energy is starting to make major headway around the world with a plethora of new technologies (and attendant potential investment opportunities) on the horizon.
The recently-released Renewables 2016 Global Status Report shows that renewables had a record year in 2015, but it wasn’t enough to make a dent in global fossil fuel consumption, which also set new records for consumption.

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.

Several years ago, when I was working on my book Power Plays, I spent a lot of time thinking about the future of energy. One thing I concluded was that solar power would become one of the world’s most important sources of energy – if not eventually the most important source of energy. I also discussed this in the 2007 column “The Future Is Solar.”
There are a couple of reasons I still believe this. But first, I should make it clear that it will be a long time before solar power rivals the consumption of oil in the global energy market.
While solar power is growing rapidly, we still use about 100 times as much energy in the form of oil (and about 90 times as much in the form of coal). Further, even though solar power is growing at a fast rate, the absolute growth in oil consumption from 2013 to 2014 was about 3 times the growth in solar power consumption. In other words, even though solar consumption grew at a 38% rate and oil consumption grew at about a 0.7% rate, this amounted to an increase in solar consumption of 11.6 million metric tons of oil equivalent versus an increase in oil consumption of 32 million metric tons.

What’s with the green parrots you may be asking? A parrot repeats what it hears without understanding what it’s saying. And by “green” I’m referring to people who, like myself, consider themselves to be environmentalists (whatever exactly that means). To the left of the green parrots is a screenshot of the “shares” from a guest post on the Clean Technica website, which has at least 99 parrots sitting on their wire.
It all started when an apparent shale gas enthusiast (Nick Grealy) wrote a 1,100 word article at his blog about the use of shale gas in France which contained the following rather cryptic throwaway sentence:
French nuclear exports help Germany, the UK, Italy and Spain accelerate their renewable uptake.
I spent a lot of time in 2015 warning that at year-end we would see a huge decline in crude oil reserves. As I have explained in the past, the reason I expected this is because of the relationship between proved oil reserves and oil prices. This relationship is important for understanding oil reserves. Some articles that recently began making the rounds made certain conclusions from this paper — A global energy assessment — in which some subtleties about oil reserves have been lost. So let’s review.
An oil resource refers to the total amount of oil in place in particular area. Generally, most of a resource can’t be technically recovered, but the resource refers to the amount that could potentially be recovered. These estimates can go up and down, but the resource is what could be recovered at 100% recovery based on current estimates.
As an example, it is estimated that the Bakken Shale centered under North Dakota contains several hundred billion barrels (bbl) of oil (the resource). However, what is technically and economically recoverable in the Bakken has been estimated at less than 10 billion barrels (<10% of the resource). CONTINUE»

Although quite upbeat about solar PV (and I’m also a big fan of solar PV), this article generated almost 300 comments because it was also frank about the limits of solar PV, and wind, and to make matters worse, he concluded the article with the following statement:
My view is that only two forms of energy — solar and nuclear power — can plausibly supply tens of terawatts without a huge environmental impact.
A few people have asked if I can reproduce more of my Forbes columns here, because they don’t like wading through the ads there to get to the content. This week I wrote an update on the progress toward cellulosic ethanol commercialization, and given my previous coverage on the topic (especially Why I Don’t Ride a Unicorn to Work) this seems like an appropriate subject to discuss here.
Last week the U.S. Environmental Protection Agency (EPA) announced that during the first quarter of 2016, just over 1 million gallons of cellulosic ethanol were produced. In fact, production for the month of March jumped 64% from the previous month to 446,000 gallons produced, the highest levels of the modern era. Production this year is well ahead of the pace in 2015, when 2.2 million gallons of cellulosic ethanol were produced for the entire year.
So, have we finally reached the long-promised realization of commercial cellulosic ethanol? CONTINUE»
