Hållbarhet med en kostnad – Vind och sol kan förstöra djurhabitat

Free, clean energy is everywhere, and with an increasing focus on sustainability worldwide, there have been notable advancements in recent years involving various approaches toward harnessing it.  However, a transition to sustainability is not always clear-cut, as even the ‘greenest’ of efforts can come with a cost, with recent studies highlighting the havoc they can wreak upon animal habitats.

Turbulenta vindar

At the forefront of controversial sustainability efforts are wind farms.  This is for a variety of reasons, which extend to include the vast areas of land required for installations, adverse health effects, harm toward certain animal habitats, and more.

More specifically, the aforementioned study now finds that elevated wind speeds and noise emissions are changing the habits of bats in the surrounding environment.

This may seem trivial initially, but it is important to remember that bats play an important role within their respective ecosystems, working not only as a means of ‘pest’ control, but as effective pollinators and seed dispersion crucial for forest regeneration.  It is because of the important role that these airborne mammals play that they are often monitored and serve as early indicators of the health of local ecosystems.

While the habits of bats are being altered as the animals learn to avoid areas with turbines, the story changes when looking at non-local, migratory birds unfamiliar with present danger.  In a recent analytical look at the deaths of 871 birds at California wind/solar farms, researchers found that “…patterns in the geographic origin of fatalities suggested that migratory movements and nonmigratory movements, such as dispersal and nomadism, influence exposure to fatality risk for these birds.”  This was shown through data generated from the analysis of hydrogen isotopes in the feathers, allowing for researchers to determine where the bird originated from.

Avbrutna hållbarhetsinsatser

Out of an abundance of caution, the potential for damage to animal habitats has already resulted in various large-scale endeavors worldwide being canceled.  One example of this comes from Canada’s Atlantic Coast in the Bay of Fundy – home of the world’s largest tides, reaching as high at 53ft (16m).

With the scale of these tides, it seems this is the perfect location to establish tidal energy projects.  Unfortunately, such efforts have been met with significant push-back over the years from entities like the Department of Fisheries, which believes tidal turbines can potentially harm local wildlife.  This has culminated in large companies like Sustainable Marine Energy Canada pulling out of the region despite investing significant time and money into the project.

Potentiella rena energialternativ

It should be noted that although there are clear and present dangers associated with the various approaches being used today that are geared toward sustainable energy production, such efforts should not be abandoned altogether.  The potential harm done by wind, solar, and tidal installations remains a fraction of that done on the Earth and animal habitats by the use of fossil fuels.

With that being said, current approaches toward sustainability may soon be looked back upon as no more than a stop-gap on our path toward a truly green future.  If the following technologies can be perfected, this will surely be the case.

Väte: Reserves of naturally occurring hydrogen were once thought to be extremely rare due to the element’s proclivity for reaction with its environment.  New methods of detection has changed this notion, as we now believe there are stores of hydrogen hidden in the Earth that could potentially be tapped into.  Producing only water vapor as a byproduct when burned, these reserves – which are large enough to serve humanity’s energy needs for generations to come – could represent our best path toward truly green energy.

Kärnfusion: Harnessing the power of the Sun is no easy feat.  For decades, this has not deterred scientists worldwide from mastering nuclear fusion.  Such monumental efforts continue to be made toward achieving this goal, as nuclear fusion is widely viewed as the ‘holy grail’ of energy production.  It can be easily contained/shut down, creates minimal waste, and, most importantly, produces more energy than is put in – meaning unlimited power.

It should be noted that each of the above alternatives to existing clean energy solutions is not a sure thing.  While there have been various monumental breakthroughs in recent years involving ‘ignition’ in nuclear fusion efforts, the technology is believed to be decades away from becoming commercially viable.

Wind is a wonderful source of clean energy, but with a growing list of other viable ‘green’ approaches on the table, one must question whether it is the best path moving forward.  The following are each companies that are actively working to develop and building out solutions involving solutions for the future, like nuclear fusion, through strategic investments of their own.

1. Cenovus Energy

CVE Prisdiagram

Cenovus Energy (CVE ) är ett kanadensiskt integrerat olja‑ och naturgassföretag som också är involverat i kärnfusionsområdet genom sin investering i General Fusion (GFUZ ), ett ledande företag inom kärnfusionsteknologi.  Även om Cenovus huvudsakliga verksamhet fokuserar på hydrokarbonproduktion, visar deras engagemang i kärnfusion ett strategiskt intresse för alternativa och framtida energiteknologier, vilket kan vara attraktivt för långsiktiga investerare som tittar på den föränderliga energimarknaden.

2. Chevron

CVX Prisdiagram

Chevron (CVX ), traditionellt känt för sin verksamhet inom hydrokarbonsektorn, har visat ett progressivt tillvägagångssätt genom att investera i kärnfusionsteknologier.  Företaget deltog i en betydande finansieringsrunda för TAE Technologies, en privat kärnfusionsstartup.  Detta steg signalerar Chevrons intresse för att diversifiera sin energiportfölj och vara en del av den framtida energitransformationen, vilket potentiellt erbjuder ett balanserat investeringsalternativ med både nuvarande relevans inom oljesektorn och framtida utsikter inom ren energi.

3. Alphabet

GOOG Prisdiagram

Alphabet (GOOG ), främst känt för sin dominans inom de digitala och teknologiska sektorerna, har utökat sin innovationshorisont genom att investera i kärnfusionsteknologi.  Företaget var också en del av konsortiet som finansierade TAE Technologies och samarbetar med Tri Alpha Energy kring teknisk utveckling relaterad till fusion.  Alphabets engagemang i kärnfusion, även om det är en mindre del av deras totala verksamhet, visar deras åtagande för banbrytande teknik och hållbarhetslösningar, vilket gör dem till ett intressant alternativ för investerare som är intresserade av en teknikjätte med en roll i framtida energiinvesteringar.
