Back in 2007, Google assembled a team of engineers to investigate the feasibility of replacing fossil fuels with renewable energy. The effort ended in 2011 with the conclusion that it can’t be done with existing technology. Two of the engineers on that team wrote about their efforts in Spectrum IEEE.org. Some excerpts from that article:
Google’s boldest energy move was an effort known as RE<C [Renewables less than Coal], which aimed to develop renewable energy sources that would generate electricity more cheaply than coal-fired power plants do. The company announced that Google would help promising technologies mature by investing in start-ups and conducting its own internal R&D.
At the start of RE<C, we had shared the attitude of many stalwart environmentalists: We felt that with steady improvements to today’s renewable energy technologies, our society could stave off catastrophic climate change. We now know that to be a false hope—but that doesn’t mean the planet is doomed.
As we reflected on the project, we came to the conclusion that even if Google and others had led the way toward a wholesale adoption of renewable energy, that switch would not have resulted in significant reductions of carbon dioxide emissions. Trying to combat climate change exclusively with today’s renewable energy technologies simply won’t work; we need a fundamentally different approach.
So our best-case scenario, which was based on our most optimistic forecasts for renewable energy, would still result in severe climate change, with all its dire consequences: shifting climatic zones, freshwater shortages, eroding coasts, and ocean acidification, among others. Our reckoning showed that reversing the trend would require both radical technological advances in cheap zero-carbon energy, as well as a method of extracting CO2 from the atmosphere and sequestering the carbon.
We’re glad that Google tried something ambitious with the RE<C initiative, and we’re proud to have been part of the project. But with 20/20 hindsight, we see that it didn’t go far enough, and that truly disruptive technologies are what our planet needs. To reverse climate change, our society requires something beyond today’s renewable energy technologies. Fortunately, new discoveries are changing the way we think about physics, nanotechnology, and biology all the time. While humanity is currently on a trajectory to severe climate change, this disaster can be averted if researchers aim for goals that seem nearly impossible.
The key is that as yet invented sources have to be cheaper than fossil fuels. The problem is that existing scalable low carbon energy sources (nuclear and renewables) are all more expensive than fossil fuels, which I’ve been pointing out for years. They make a stab at explaining why wind and solar are more expensive but trust me, their explanation will largely fall on deaf ears when presented to renewable energy enthusiasts who either don’t want to hear it or are incapable of comprehending it. They argue that subsidies for renewables and nuclear to compete with fossil fuels are essentially a financial penalty to fossil fuels which simply shift their use to another part of the planet (export of oil, gas, and coal, along with manufacturing jobs).
The argument goes something like this:
Real environmentalist: “We should not allow the destruction of orangutan habitat for palm oil biodiesel!”
Apologist: “In fact by displacing fossil fuels, palm oil biodiesel is helping orangutans, as well as everything else that is alive on the planet! Orangutans are at serious risk due to climate change. Some primate species are forecast to to lose more than 95% of their current ranges!” CONTINUE»
It makes little sense to be anti-solar energy in this day and age, although it does make sense to do it right. Even solar can be done wrong. Usurping farmland, forest, or pristine desert tortoise habitats for solar should be against the rules.
I was motivated to do this post by a rare, cloudless, 50 degree day in the dead of winter. CONTINUE»
Energy’s Brief Appearance in the State of the Union Address
Energy issues received scant mention in Tuesday’s State of the Union speech, consisting mainly of a victory lap for the President’s “all of the above” formulation and a somewhat contradictory promise to place even more federal lands off-limits to drilling. While browsing through reactions from various energy leaders and environmental groups I was intrigued by one critique of Mr. Obama’s approach from an environmental NGO, arguing that he should instead be placing the country’s bets on “best of the above” energy. They weren’t the only ones to object to the current approach.
It’s clear from their statement that Earthjustice has definite ideas about what’s best and what isn’t, but their comment merits further discussion. After all, who could argue against supporting the best energy sources? And isn’t all of the above just a sop to the status quo, in which a diverse array of energy sources dominated by fossil fuels provides the energy for the rest of the economy?
Obama and “All of the Above”
As President Obama noted Tuesday, his reference to an “‘all of the above’ energy strategy”–a debatable characterization in itself–referred to a key phrase in his 2012 address to Congress. It’s worth recalling the context, in an election year in which the Republican nominee was certain to focus on conventional energy when it was delivering US production growth in both oil and natural gas that couldn’t have been imagined just a few years earlier.
Last month the Department of Interior (DOI) Bureau of Land Management (BLM) held its first competitive auction for commercial solar development on public lands, offering three parcels for lease with a collective acreage of 3,700 in the San Luis Valley of Colorado. The three leases are located in two of DOI’s designated “Solar Energy Zones,” which the DOI carved out for quick solar development due to access to existing transmission, limited environmental impacts, and cheap land rental.
If fully developed, these two Solar Energy Zones could potentially produce 400 MW of energy, enough to power an estimated 125,000 homes. Unfortunately DOI was alone in their enthusiasm as the auction drew zero bids from solar companies. Moving forward, DOI should learn from this initial failure and expand its Solar Energy Zones to also act as a test bed for next-generation clean energy designs, not just off-the-shelf technologies.
The Energy Experts Reconvene at the WSJ
Generally when I find myself having to write a follow-up post to something I wrote, it’s because I obviously didn’t make my points clearly enough. I found this to be the case during a lively Twitter discussion following my latest contribution to the Wall Street Journal’s (WSJ) Energy Experts Panel. But I love these sorts of discussions because they help me hone the message I am trying to deliver.
This week the WSJ began publishing the latest round of answers to questions that were submitted to their energy panel several weeks ago. The first question answered this week was: What is the single biggest misconception people have about renewable energy in the U.S.?
First, if you don’t know about the WSJ Expert Panels, I explained that in some detail here. Essentially, the WSJ has groups of experts in different fields, and they pose questions on various topics. We are asked to write ~ 300-word answers to these questions, which often means leaving out caveats and/or clarifications. The answers are more detailed than the 140 characters allowed by Twitter, but some topics leave a lot of issues unaddressed with just a 300-word answer. CONTINUE»
Today I begin a series that looks at the recently released 2013 BP Statistical Review of World Energy. Because the past two posts have dealt with the Keystone XL pipeline project, I thought it would be a good change of pace to kick off this series by looking at the current global picture of renewable energy. Additional articles in the series will examine the world’s fossil fuel consumption and carbon emissions.
Overall, renewable energy once more displayed very strong growth in 2012. Renewable energy accounted for 2.4% of global energy consumption in 2012, and a record 4.7% of global power generation.
The only renewable energy sector that stagnated in 2012 was the production of biofuels. For the first time since 2000, global biofuels production declined. This decline was primarily a result of a 4.3% drop in the production of biofuels in the US (but I expect production will be higher for 2013).
An Oft-Used Energy Slogan
Last week, Real Clear Politics and API hosted an energy summit in Washington, DC entitled, “Fueling America’s Future”. It was intended to provide a quick overview of most of the key technologies and issues associated with an all-of-the-above energy strategy for the United States. Going through the highlights of the webcast gives me an opportunity to introduce my point of view to a new audience at Energy Trends Insider. I’d sum that up as “All of the Above”, with asterisks for the proportions and situations that make sense.
This slogan, at least in the manner in which it has been espoused by politicians in both parties, has attracted fair criticism for being overly bland and safe. I suspect that critique reflects a general sense that our energy mix has always been composed of all of the above, or all of the technologies that were sufficiently proven and economic to contribute at scale at any point in time. However, as both our technology options and choice criteria expand, our understanding of the evolving energy mix is hampered by metrics and assumptions that are overdue to be revisited.
