New Record Low Solar Price in Abu Dhabi – Costs Plunging Faster Than Expected
21 Sep, 2016
The price of solar power – in the very sunniest locations in particular – is plunging faster than I expected. I’ve been talking for years now about the exponential decline of solar power prices. I’ve often been called a wide-eyed optimist. Here’s what those projections…
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…

This is part 3 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, below, talks…
R e a d M o r eHunger is at an all-time low. We can drive it even lower.
9 Sep, 2015
A few observations on hunger, extracted from the latest FAO report on The State of Food Insecurity, 2015 1. The percent of humanity that’s hungry is at an all-time low. According to FAO, 11.3% of the world is undernourished. Most of that hunger is concentrated in…
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 eHow Cheap Can Solar Get? Very Cheap Indeed
10 Aug, 2015
This is part 1 of a series looking at the economic trends of new energy technologies. Part 2 looks at the dropping price and increasing reliability of wind power. Part 3 looks at how cheap energy storage can get (pretty darn cheap). Part 4 looks…
R e a d M o r eNew Solar Capacity Factor in the US is Now ~30%
9 Aug, 2015
The capacity factor of new utility scale solar deployed in the US in 2010 was 24%. By 2012 it had risen to roughly 30%. The rising capacity factor of new solar projects is part of why the cost of electricity from new solar is dropping…
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 eWhy Energy Storage is About to Get Big – and Cheap
14 Apr, 2015
tl;dr: Storage of electricity in large quantities is reaching an inflection point, poised to give a big boost to renewables, to disrupt business models across the electrical industry, and to tap into a market that will eventually top many of tens of billions of dollars…
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 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 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 eThe Shrinking Dominance of the Big Dogs in Tech
12 Jan, 2014
“In 1981, the top ten technology companies represented 95% of the global IT market cap. Today, that share has fallen to 26% and the ratio continues to fall.” Microsoft, IBM, DEC, HP, and so on were once titans. Apple, Google, and Facebook may be…
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 eIncome, Energy Use, and Life Expectancy
14 Nov, 2013
One of the best indicators of human well-being is life expectancy. High life expectancy often means low infant mortality and typically correlates with ample access to food, medicine, shelter, and education, as well as low levels of disease and violence. Interestingly, during an economic development…
R e a d M o r eChina’s Tipping Point on Environment?
29 Jul, 2012
Chinese environmental protesters have won the cancellation of an industrial waste pipeline that would have dumped waste from a paper factory into the ocean near the town of Qidong. This is not the first such victory. The Guardian notes that: The protest followed similar demonstrations against projects in…
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 eIs Automation the Handmaiden of Inequality?
3 May, 2012
In Technology Review, Christopher Mims asks if the increasing automation of US industry has contributed to growing inequality, by bringing its gains to factory owners rather than workers. Here’s how I would interpret the odd coincidence of these two trends: in a perfectly capitalist system,…
R e a d M o r eIs Moore’s Law Really a Fair Comparison for Solar?
17 Mar, 2011
[This is an update of a post I first wrote in March of 2011, responding to criticism of the analogy of Moore’s Law for solar power. Updating in April 2015, on the 50th Anniversary of Moore’s Law, in light of renewed conversation on this topic.…
R e a d M o r eThe Exponential Gains in Solar Power per Dollar
17 Mar, 2011
My post on the Moore’s Law-like exponential gains in solar power per dollar went up at Scientific American yesterday. Reprinting here with permission. The sun strikes every square meter of our planet with more than 1,360 watts of power. Half of that energy is absorbed…
