2014 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 eSolar and Wind Plunging Below Fossil Fuel Prices
5 Oct, 2014
Asset management firm Lazard has a fascinating new analysis of renewable and other energy prices out. There are a huge number of insights in this, from an outside analyst whose primary interest is financial. (Those are, in my mind, the most objective analysts in this…
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 eSolar Power Prices Dropping Faster Than Ever
14 Nov, 2013
In 2011, I wrote a piece for Scientific American on the exponential price decline in solar power. I haven't had a chance to fully update that piece, but two quick notes. First, the price decline in solar cost per watt has, if anything, accelerated since then.…
R e a d M o r eThe Sunlight is Where the Energy Poverty Is
14 Nov, 2013
The future world energy system will undoubtedly be a mix of many different energy technologies – nuclear, hydro, wind, solar, and some fossil fuels for decades and decades to come. Yet I’m particularly optimistic about solar. One reason is its incredible price trajectory, a trait…
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 eCombining Current Tech Could Make Solar Cheaper than Coal
22 Feb, 2012
By the end of the decade, manufacturers in the United States could make solar panels that are less than half as expensive as the ones they make now. That would be cheap enough for solar power to compete with electricity from fossil fuels, according to…

R e a d M o r eCarbon Nanotubes Could Replace Rare Earth Indium in Solar Cells
27 Sep, 2011
A frequently voiced concern about solar energy is the dependence of solar cells on rare earth elements such as indium. While rare earth elements are actually far more plentiful than their name suggests, it’s also encouraging to see studies showing that components made from abundant…
