Yes, Blockchain Can Help Us Solve Climate Change – Why I Joined Nori
10 Sep, 2018
Over the last two years, as both an angel investor and a public speaker on energy and climate, I’ve looked at least a few dozen startups and proposals on how to use blockchain or new crypto coins in energy or climate. I’ve passed on all of…
R e a d M o r eTo Fight Climate Change in the Trump Era, Focus on the States
20 Nov, 2016
Summary: Focus on the states. Advocate for clean energy. (This is a follow-up to my post on pushing for progress at the state level.) Short Version If you read nothing else in this post, follow these three steps: Note: Say “Clean Energy” instead of “Climate Change“…
R e a d M o r eWhy I’m Starting the First AngelList Cleantech Syndicate
22 Feb, 2016
I’ve been writing and speaking about the incredible pace of solar, wind, and storage for years. I’ve been quietly investing in startups in that space as well. Today I’m taking a new step: I’m launching an AngelList Syndicate specifically focused on investing in clean energy…
R e a d M o r eMy Carbon Price Presentation to the Washington Legislature
21 Feb, 2016
On Friday Feb 19th I testified before the Washington House Environment Committee on the topic of carbon pricing, both from the point of view of a member of the executive committee of CarbonWA (I-732) and as a concerned citizen. You can watch the full testimony (including…
R e a d M o r eRenewables are Disruptive to Fossil Fuels
18 Feb, 2016
A shorter version of this post first appeared at the Marginal Revolution blog. Cleantech, and specifically renewables like solar and wind (and their fellow traveler energy storage) are disruptive to fossil fuels. Over the last 5 years, the price of new wind power in the US…
R e a d M o r eHow Far Can Renewables Go? Pretty Darn Far
31 Jan, 2016
This is part 4 of a series looking at the economic trends of new energy technologies. Part 1 looked at how cheap solar can get (very cheap indeed). Part 2 looked at the declining cost and rising reliability of wind power. Part 3 looked at…
R e a d M o r eHow to Think About the Paris Climate Deal
13 Dec, 2015
Over the weekend, the world agreed to a new climate deal. Brad Plumer explains it well. Reactions range from celebration to dismissal of it as a fraud. It’s rare to see James Hansen (a tireless campaigner for addressing climate change) and Bjorn Lomborg (one of the…

R e a d M o r eHow Steady Can Wind Power Blow?
30 Aug, 2015
This is part 2 of a series looking at the economic trends of new energy technologies. Part 1 looked at how cheap solar can get (very cheap indeed). Part 3 looks at how cheap energy storage can get (pretty darn cheap). Part 4 looks at…
R e a d M o r eCitizens Led on Gay Marriage and Pot. We Can on Climate Change Too.
15 Jul, 2015
A decade ago, it was nearly inconceivable that in 2015, gay marriage would be legal across the US and marijuana fully legal in four states plus the District of Columbia. Yet it happened. It happened because citizens who wanted change led, from the bottom up,…
R e a d M o r eSolar Cost Less than Half of What EIA Projected
30 Jun, 2015
Skeptics of renewables sometimes cite data from EIA (The US Department of Energy’s Energy Information Administration) or from the IEA (the OECD’s International Energy Agency). The IEA has a long history of underestimating solar and wind that I think is starting to be understood. The US…
R e a d M o r eSolar: The First 1% Was the Hardest
18 Jun, 2015
Solar power now provides roughly 1% of the world’s electricity. It took 40 years to reach that milestone. But, as they say in tech, the first 1% is the hardest. You can see why in this chart below. As solar prices drop, installation rate rises.…
R e a d M o r eHow Much Land Would it Take to Power the US via Solar?
8 Apr, 2015
I’ve seen some pieces in the media lately questioning this, so allow me to point to some facts based on real-world data. tl;dr: We’ll probably never power the world entirely on solar, but if we did, it would take a rather small fraction of the…
R e a d M o r e2014 Was a Good Year: Better Than You Remember
21 Dec, 2014
Eric Garner. Michael Brown. The Sony hack and surrender to fear. 2014 seems to be ending on a crappy note. My twitter feed is full of people expressing good riddance to the year. 2014 was better than that. I want to take a moment to…
R e a d M o r eThe Learning Curve for Energy Storage
30 Sep, 2014
Energy storage prices are dropping fast. If you follow me, you’ve seen me write about this before. Energy storage prices have in fact been dropping exponentially for at least 25 years. Here’s a new piece of analysis – a model that uses a 20% learning…
R e a d M o r eThe Renewable Energy Revolution
29 Sep, 2014
Transforming the world’s energy supply will take decades. It is a very tall order. But it’s starting. The price of renewables – and energy storage – continues to plunge, putting them on a path to being cheaper than any other form of energy within the…
R e a d M o r eCarbon Prices Drive Clean Energy Innovation
11 Mar, 2014
I want to point out something I see commonly missed. Carbon prices accelerate innovation that brings down the price of green energy. So do renewable energy portfolio standards, green energy subsidies, and a whole swath of other climate policies. They do this by increasing the scale of…
R e a d M o r eArctic Sea Ice: Less in November 2013 than Summers Before 2006
26 Dec, 2013
(This is a correction of a previous post that stated that there was less Arctic sea ice in December than in any summer before 2007. That post used a PIOMAS anamoly graph, which was not appropriate.) The Arctic is melting. That's a problem. Ice reflects 90% of…
R e a d M o r ePieces I’ve Written Around the Web
8 Sep, 2013
Over the last few months (and a bit over the past few years) I wrote a number of pieces around the web, primarily on energy, sustainability, genetically modified foods, and economic growth. I did a poor job of linking to them on my own site.…
R e a d M o r ePricing Nature to Save the Planet
27 Jun, 2012
New Scientist, covering Rio+20, talks about putting a price on the natural world: Green economics, the theory goes, will work by quantifying nature and giving it a cash value. As Steiner put it: “Factoring natural capital into the bottom line will bring the real wealth…

R e a d M o r eCan We Capture All the World’s Carbon?
16 May, 2011
I originally posted this at Scientific American. Reposting here with permission. In 2011, the world will emit more than 35 billion tons of carbon dioxide. Every day of the year, almost a hundred million tons will be released into the atmosphere. Every second more than…
R e a d M o r eKey Trends of the Next 25 Years
21 Mar, 2011
Michell Zappa has a fascinating infographic attempting to lay out timelines for future technologies over the next 25 years. It’s an impressive job of collecting data and laying it out in a way that someone can explore. It’s worth playing with. Click through on the…
R e a d M o r ePersuading Climate Skeptics – Why We Need Republican Experts
18 Mar, 2011
New Scientist has an interesting article on research into what persuades people on scientific issues. The key finding is that there’s a major impact of hearing the evidence from someone who has similar political and social outlooks. Experts who are similar to listeners are inherently…

R e a d M o r eGlobal Warming: Risk of Methane Release from Frozen Tundra
5 Dec, 2008
Now this is scary. The linear rate of global warming, in and of itself, is scary only in the somewhat long term (100+ years or so). The real risk with global warming is runaway feed-forward loops. E.g., one that you hear about often is that…
