Today\u2019s Contemplation: Collapse Cometh CCXXVII\u2013
\n<\/b>We\u2019re Saved! Wave Energy.<\/b><\/h3>\n

A relatively recent <\/span>article<\/span><\/a> and some social media click-bait site posts have me exploring the potential of wave energy-harvesting technologies. But as with every such technological promise examined in the last dozen or so Contemplations, a close scrutiny of wave energy shows that it does not live up to the hype its marketers and supporters make. The challenges for this technology are not just technical and economic, but systemic in nature and help to demonstrate the flaws in the commonly held belief that humanity can innovate its way out of ecological overshoot.\u00a0<\/span><\/p>\n

What is Wave Energy?
\n<\/b>This technology attempts to harvest energy from the movement of ocean waves in order to generate power for use by humans. As wind transfers its energy to the surface of oceans through friction, kinetic and potential energy is created from the water\u2019s motion and its being lifted against gravity. Specialised technologies (wave energy converters, WEC) capture this energy and convert it to electricity for human use. Obviously, this technology is rather restricted to specific areas of the world with its prime location being the west coast of continents between 30\u00b0 and 60\u00b0 latitude where the strongest winds occur and create the most powerful waves.\u00a0<\/span><\/p>\n

There exist a variety of WECs: floating buoys that move up and down with the swelling of waves to drive an internal generator or hydraulic pump\u2013known as point absorbers; reservoirs with walls located at sea level that get filled by wave action and then drain to turn a low-head turbine\u2013known as overtopping devices; flaps or panels affixed to the seabed in shallow waters that get moved back-and-forth with the water action driving a generator\u2013called oscillating wave surge converters; and a number of others.\u00a0<\/span><\/p>\n

The energy harvested from the world\u2019s ocean waves is potentially enormous. The International Panel on Climate Change estimates that globally some 29,500 terawatt hours of energy could be provided to humanity (see <\/span>this<\/span><\/a>). Despite this potential, the harvesting of wave energy is still in its infancy with most projects in their prototype and testing phase.\u00a0<\/span><\/p>\n

The benefits of this type of potentially \u2018clean and sustainable\u2019 energy production are seductive. The power density is high, much denser than that provided by wind turbines or solar photovoltaic panels. Wave activity is predictable with activity being forecast relatively accurately days in advance aiding in grid management. And, the energy source can be provided almost constantly, day and night all year long.\u00a0<\/span><\/p>\n

Advocates highlight these benefits and argue it is one of the most promising future contributors to a \u2018clean\u2019 energy mix, especially for remote coastal and island communities who currently depend upon expensive diesel generators. It can also provide relatively consistent power generation to supplement more intermittent \u2018renewables\u2019.\u00a0<\/span><\/p>\n

High power density. Constant and predictable energy generation. And \u2018clean and sustainable energy\u2019. What\u2019s not to love?<\/span><\/p>\n

Well\u2026<\/span><\/p>\n

\n

There are a number of fundamental factors that challenge this technology before we even discuss the broader implications of chasing another technology to add to humanity\u2019s seemingly insatiable energy consumption.\u00a0<\/span><\/p>\n

Costs
\n<\/span><\/i>Current estimates of costs for wave energy generation are quite high relative to other technologies. The material challenges, complex manufacturing, and structural expenses all push up prices. Those marketing it argue that economies of scale will bring these costs down once the technological components are more widely produced.\u00a0<\/span><\/p>\n

Direct Environmental Impacts<\/span><\/i>
\n<\/span>The direct impacts on marine wildlife of this technology are quite concerning to some. They include: underwater noise; collisions and entanglement; electromagnetic fields; habitat change and loss; water quality impacts; and, altered hydrodynamics and sediment transport. The long-term consequences are not yet known but are in the process of being studied at current test sites.\u00a0<\/span><\/p>\n

Technical and Material Hurdles
\n<\/span><\/i>The harsh marine environment presents a number of intractable issues: corrosion from saltwater; biofouling from organisms like barnacles; and extreme mechanical forces from storms.\u00a0<\/span><\/p>\n

These factors lead to metal fatigue, increasing drag, and monumental survivability challenges. Finding durable materials that can withstand these conditions at a reasonable cost is extremely difficult. Research continues on how best to address these issues but for the moment using high-strength steel coated with a specialised thermochemical layer provides some protection from corrosion and reduces organism attachment.\u00a0<\/span><\/p>\n

Withstanding significant storm waves is a must but very challenging to guarantee, especially at a reasonable cost. Concrete and\/or steel structures offer protection for some designs. This particular \u2018solution\u2019 can increase costs dramatically, perhaps by 25-50%, and its negative environmental impacts are significant.\u00a0\u00a0<\/span><\/p>\n

Research into novel materials with which to construct WECs and ensure suitable energy conversion continues. These include: rubber-like material that generates power when stretched\u2013dielectric elastomers; Polyvinylidene Fluoride combined with graphene that will generate electricity when flexed by waves\u2013piezoelectric composites; and, devices that generate power via friction between polymers\u2013triboelectric nanogenerators. These are all rather expensive and require significant chemical and material-refinement industrial processes for their production.\u00a0\u00a0<\/span><\/p>\n

Commercial Viability
\n<\/span><\/i>The monetary and resource costs for this technology are substantial, and one of the main reasons they are not commercially widespread. Massive steel and concrete structures upon which to attach many WECs are required for several types. Sea transportation and deployment is exorbitantly cost prohibitive. Advocates argue that they can be made far more reasonable in cost with economies of scale and continued research. Note the common refrain of many energy-technology cheerleaders: \u201cWe need more funding for research and once a massive build out is carried out, this latest \u2018saviour\u2019 will be cost competitive\u201d\u2013in other words, pay us now and you\u2019ll reap the benefits some time down the road.<\/span><\/p>\n

Even if all the above cost and engineering hurdles were to be overcome, the foundational flaws that plague proposed \u2018clean\u2019 technologies remain.<\/span><\/p>\n

Common Energy Technology Issues of Concern
\n<\/b>Claims of Being \u2018Clean and Sustainable\u2019
\n<\/span><\/i>Once deployed and functioning, the claims regarding generation of \u2018clean and sustainable\u2019 energy are easy to make (as long as you can ignore the immediate environmental impacts). But prior to such deployment there are a host of industrial processes employed and resources required, especially hydrocarbons and various materials\/minerals. Yes, the impacts are \u2018mostly\u2019 upfront, but they are there and quite substantial nonetheless.<\/span><\/p>\n

And the ever-present narrow focus upon carbon emissions\u2013due to carbon tunnel vision that seems to permeate all discussions and interpretations of \u2018clean energy\u2019\u2013is problematic in its overlooking of ecological systems destruction beyond the narrow perspective this focus causes. Any mass-produced, industrial technology entails a destructive lifecycle: from extraction and refinement of materials, to manufacture and distribution, and finally to reclamation or disposal.\u00a0<\/span><\/p>\n

Even if lifecycle analyses of a technology demonstrates less carbon intensity than another, this does nothing to address the other ecological systems damage being carried out nor the issue about continuing to chase growth and complexities via complex industrial-based energy technologies. \u2018Greening\u2019 a supply chain or reducing the \u2018footprint\u2019 of such technologies serves more to create comforting narratives and rationalisations than addressing the fundamental predicament of ecological overshoot our species\u2019 growth and activity has created.<\/span><\/p>\n

Replacement Theory
\n<\/span><\/i>As with every other energy source, the power generation being created by WECs is adding to humanity\u2019s energy consumption; it is not replacing the hydrocarbons that its proponents argue it is.\u00a0<\/span><\/p>\n

But even beyond this rather simplistic narrative about non-renewable, renewable energy-harvesting technologies replacing hydrocarbons, is the evidence that they are part and parcel of the problem. Every step in their supply chains and manufacturing requires hydrocarbon inputs. And this is especially so for WECs and their chemical coatings, concrete and steel structures, plastic and steel components, etc.. These are hydrocarbon-dependent technologies and are helping to draw down ever more quickly this finite material.\u00a0<\/span><\/p>\n

In addition (no pun intended here), these new energy technologies are fuelling the larger fire of humanity\u2019s resource consumption. Hydrocarbon extraction continues to increase year-over-year, as does the energy use by our species. There appears to be no replacement taking place.\u00a0<\/span><\/p>\n

Technological Chickens Yet to Hatch
\n<\/span><\/i>There are two fundamental issues that get glossed over during discussions about \u2018renewables\u2019 that get to the heart of notions regarding human society\u2019s \u2018sustainability\u2019.<\/span><\/p>\n

First, there exists \u2018embodied hydrocarbons\u2019 a plenty. All extraction and refining of material and minerals are only possible because of hydrocarbons. And virtually all large-scale industrial manufacturing is powered by and made from products reliant on hydrocarbons. And this is a finite energy source that has hit significant diminishing returns.\u00a0<\/span><\/p>\n

Second, the rebound effect and consumption growth that accompanies energy efficiencies or new energy sources. Known as Jevon\u2019s Paradox, this phenomenon sees energy generation such as that from WECs added to the global total rather than displacing old sources; and helping to keep alive the comforting narratives that the perpetual growth chalice is within reach. Coal, for example, did not replace biomass as a heat source; the planet is seeing increasing amounts of biomass used for a variety of purposes. Oil did not replace coal as an energy source; we are seeing increasing amounts of coal mined every year. \u2018Renewables\u2019 are not replacing oil for energy generation; they are adding to our overall energy consumption.\u00a0<\/span><\/p>\n

\"\"<\/a>ourworldindata.org<\/span><\/a>\u00a0<\/span><\/h6>\n

More to the point, much of the argument for the technologies marketed as being \u2018cleaner, sustainable, and capable of replacing hydrocarbons\u2019 is based almost invariably upon as-yet-to-hatch technological chickens. If only more research funds are steered into them and\/or funds are made available to build them out extensively, then the utopian dreams of ecomodernists and cornucopians will come to fruition. Any. Moment. Now. Just have faith. And placing human survival on technological breakthroughs that are always just over the horizon is a form of collective delusion.<\/span><\/p>\n

Conclusion
\n<\/b>Wave energy advocates present an attractive vision of dense, predictable, and constant \u2018renewable\u2019 power generation that\u2019s \u2018clean and sustainable\u2019. Upon closer examination, however, such a promise is another in a rather long line of technologies that cannot possibly meet the hype. From corrosion and survivability to prohibitive costs and habitat disruption, there are serious material, economic, and environmental challenges to any near-term viability and possible scalability.<\/span><\/p>\n

Perhaps more importantly this technology, like other \u2018clean and sustainable\u2019 ones, is constrained by two major systemic issues. First, it is an energy source being added to humanity\u2019s seeming insatiable energy consumption and not a replacement for \u2018dirtier\u2019 energy sources as most such technologies are marketed as being. It is almost totally dependent upon hydrocarbon-intensive supply chains and production and thereby can never be a \u2018replacement\u2019.\u00a0<\/span><\/p>\n

Second, similar to all other \u2018renewable\u2019 technologies being hyped globally it helps to perpetuate a dangerous illusion that humanity can innovate its way clear of the consequences of ecological overshoot while maintaining perpetual economic and energy-demand growth. Wave energy is yet another distraction helping to create a comforting narrative about human progress while drawing down finite resources, destabilising ecological systems, and overloading planetary sinks.\u00a0<\/span><\/p>\n

The evidence appears to be clear: no technology can \u2018save\u2019 a global civilisation determined to pursue infinite growth on a finite planet. We\u2019re telling ourselves comforting stories by believing in the tales of technological salvation and exacerbating our predicaments by acting upon them.\u00a0<\/span><\/p>\n

Afterword<\/strong>
\n<\/span>A bit of research revealed that the <\/span>site<\/span><\/a> of the original article that spurred this Contemplation described itself as an \u201c<\/span>internet destination for those who care about our planet and environment and want to make a difference\u2026[and] for people who care about the Earth and have an interest in nature, the environment, and science. It\u2019s for those who care about our planet and want to make a difference.<\/span><\/i>\u201d\u00a0<\/span><\/p>\n

The site had many, many articles on technological \u2018solutions\u2019 to our various predicaments but few on sociocultural shifts to address or mitigate our plight. For example, I found close to a dozen on wave energy and only a single one on degrowth; I found countless numbers on \u2018clean energy\u2019 technologies (from the best investment ventures to support research and where to mine the best lithium, to hydrogen- and fusion-based energy and how the renewable energy transition will boost the economy), and only four on permaculture. Pushing an ecomodernist\/cornucopian \u2018technology will save us\u2019 narrative. Not very caring about the planet, environment, or Nature in my opinion.\u00a0<\/span><\/p>\n

We\u2019re telling ourselves comforting stories\u2013precisely the kind promoted by \u2018caring\u2019 planetary sites\u2013by believing in tales of technological salvation, thereby exacerbating the very predicaments we seek to solve.<\/span><\/p>\n

What is going to be my standard <\/span>WARNING\/ADVICE <\/b>going forward and that I have reiterated in various ways before this:<\/span><\/p>\n

\u201cOnly time will tell how this all unfolds but there\u2019s nothing wrong with preparing for the worst by \u2018collapsing now to avoid the rush\u2019 and pursuing self-sufficiency. By this I mean removing as many dependencies on the Matrix as is possible and making do, locally. And if one can do this without negative impacts upon our fragile ecosystems or do so while creating more resilient ecosystems, all the better. Building community (maybe even just household) resilience to as high a level as possible seems prudent given the uncertainties of an unpredictable future. There\u2019s no guarantee it will ensure \u2018recovery\u2019 after a significant societal stressor\/shock but it should increase the probability of it and that, perhaps, is all we can \u2018hope\u2019 for from its pursuit.\u201d<\/span><\/p>\n
