What are the False Solutions to the Climate Crisis, and How Can We Recognise Them?

 

Daily life is now laced with a palpable sense of fear for the planet’s future. This sense remains relatively new. Just a few years back, the climate crisis sat on the periphery of mainstream media. True, you would have been hard-pushed to find someone who was not at the very least somewhat aware of the topics of global warming, pollution, carbon footprints and their risks – but, these days, the subject is largely unavoidable. It dominates headlines even when the world is in the grips of another crisis – although, admittedly, these crises often share their own links with global warming.

From natural disasters – flooding, snowstorms, and hurricanes – to the biggest headliner in recent history – the Coronavirus – all roads lead back to human life, and its untenable ways.

There is, unfortunately, very little that the average individual can do. Governments, corporations and businesses are feeling pressurised to put forth solutions – but, as is growing increasingly obvious, so much is swayed by the drive toward profit, market dominance, and a willingness to sacrifice long-term successes for short-term gains.

As such, many of the solutions that are being put forth are not as they appear to be. They offer false promises and reassurances in place of progress, and need to be hindered wherever possible.


Carbon Credits

For businesses, the solution to the spiralling climate crisis is relatively simple: reduce carbon emissions wherever possible, and invest more into restorative technologies and projects like soil regeneration, tree planting, and renewable energies.

Of course, the reality is trickier than that – companies still need to turn a profit in order to survive, after all, and allocating time and resources without harming the bottom line is a tricky balancing act.

It’s no surprise, then, that some companies are looking to the simpler alternative – the path of least resistance, that enables them to continue on without disruption while still being able to demonstrate a stronger sense of social responsibility without flat-out lying to customers.

In this instance, the ‘path of least resistance’ appears in the form of carbon credits. Rather than actively reducing their own carbon emissions, companies can ‘buy’ a permit for carbon production in the form of credits. These credits will ideally decrease over time, meaning companies need to work gradually toward lower emissions.


Bioplastics

The benefits of recycling – of reducing the daily influx of non-compostable and, at times, toxic waste making its way into the world’s oceans – need no introduction, and plenty of initiatives have been undertaken to minimise an individual’s impact on the environment.

However, this area is not without its false promises. The term ‘bioplastics’ itself is a vague term with no specific definition. It’s akin to those common marketing buzzwords – ‘natural’, ‘environmentally friendly’, and ‘conscious’.

But numerous studies have discovered toxic chemicals in a long list of bioplastics. What’s more, a single ‘bioplastic’ single-use cup, for instance, is likely to have a significant carbon footprint. Creating bioplastic is an energy- and resource-intensive process – one that may, by some estimates, be doing more harm than the production of standard, single-use plastics. 


Carbon Capture, Use, and Storage (CCUS)

This is, perhaps, one of the most noteworthy examples we have of the energy sector seeking to profit off of their own carbon footprint.

Put simply, it is the practice of using captured carbon (carbon emitted by the industry’s oil giants, during extraction) to aid in enhanced oil recovery – a practice that requires large amounts of CO2 to be pumped into near-depleted oil wells, in order for further oil to be extracted.

This was not how it was presented to the public, however. Oil companies merely stated that, with public funding, they would work to capture their own CO2 emissions and prevent them from leaking out into the atmosphere and contributing to global warming.

The practice was first introduced in the 1970s, but remains a significant problem today – and offers all the proof we need of the industry’s interest (or lack thereof) in protecting the planet from its own damaging practices.


Greenwashing

This is a topic we covered recently, and has one of the most direct impacts on consumers looking to do their bit for environmental reform. Companies looking to take advantage of the large (and growing) demographic of consumers who want to make more ethical, eco-conscious choices – and who are willing to invest more in order to make those choices – are taking advantage of a wide range of vague terms, marketing ploys, and rebrands that hint toward a heightened sense of social responsibility, without the legwork or investment.


Fracking

Fracking has seen its fair share of the spotlight in recent years. It is the practice of capturing natural gas buried deep underground by means of highly pressurised ‘injections’ of liquid.

If that sounds like a risky endeavour, you’d be right. Nonetheless, fracking has made a considerable mark on the landscape in recent years – and the government has remained relatively taciturn on the risks voiced by many groups and individuals. Tens of thousands of wells have been erected in the UK alone in a bid to collect useful natural gases like methane.

The proposed benefits are cheaper gas and better employment opportunities.

But fracking can easily pollute water supplies, and its ability to ‘unlock’ massive amounts of cheap, natural gas threatens to derail the shift toward renewable technologies. It means that the focus remains on fossil fuels, and depleting natural resources of potential pollutants, rather than investing those millions into increasing the UK’s capacity for sustainable energy production.

Given the fact that technologies like solar PV are far less impactful on the environment and work by harvesting a free, infinitely available, and non-toxic source of energy, it is baffling to an outsider why the government would so doggedly pursue fracking over its healthy alternatives.


How Do We Spot False Solutions?

False solutions come in many forms, as evidence by the different projects and technologies listed above. False solutions often seem too good to be true – but that doesn’t prove a useful yardstick when plenty of genuinely useful solutions are also able to make big promises.

False solutions so often come in the form of ‘alternative alternatives’. By now, we all know the cornerstones of a green recovery. Renewable energy derived from solar, wind, wave, and biothermal technologies need to replace our dependence on fossil fuels. Resources derived closer to home must be used more wherever possible. Single-use must be avoided as much as is realistic. Nature must be supported in healing.

So many of the false solutions seem to have been dreamed-up in an attempt to avoid these simple solutions. The government, in their move toward nuclear energy, have failed to put forth a compelling argument as to why it is superior to the many truly sustainable alternatives.

They also depend upon terms that have no clear meaning. ‘Net zero’ carbon emissions is not the same as ‘zero’ carbon emissions, for instance – but, to the layperson, what does it mean? Bioplastics is a portmanteau that makes use of a popular buzzword in (supposedly) green circles.

There will always be ways of cutting to the core of supposed solutions to the climate crisis – but, for that, we need to remain open-minded to counter-arguments, and focused intently on the technologies and solutions that, by now, we all definitively know to work.


Solar Ground Mounting System

Solar Mounting System

Common Types of Photovoltaic Brackets and Basic Science Popularization of Brackets

 

Photovoltaic mounting structure is an important part of photovoltaic power station, carrying the main power generation of photovoltaic power station. Therefore, the choice of solar mounting structure directly affects the operation safety, damage rate and construction investment income of photovoltaic modules.

solar mounting  system


When choosing a photovoltaic mounting structure, it is necessary to choose a solar mounting structure of different materials according to different application conditions. According to the different materials used for the main force-bearing rods of the photovoltaic mounting system, it can be divided into aluminum alloy mounting structure, steel mount and non-metal mount (flexible mount), of which non-metal mount (flexible mount) is less used, and aluminum alloy mount And steel brackets have their own characteristics.


The non-metal mount (flexible mount) is a steel cable prestressed structure to solve the span and height requirements of sewage treatment plants, complex terrain mountains, low-load-bearing roofs, forest-light complementary, water-light complementary, driving schools, expressway service areas, etc. Limit the technical problems that the traditional mount structure cannot be installed, and effectively solve the existing difficulties in the construction of photovoltaic power plants in valleys and hills, serious sun shading, and low power generation (compared with photovoltaic power plants in flat areas, it is about 10%-35% lower) ) The disadvantages of the power station mount are poor quality and complex structure.


In general, the non-metal mount (flexible mount) has a wide range of adaptability, flexibility of use, effective safety and perfect secondary land use economy, which is a revolutionary creation of photovoltaic mounting structure.

A reasonable form of photovoltaic mounting structure can improve the system's ability to resist wind and snow loads. Reasonable use of the characteristics of the photovoltaic ground mounting system in terms of load can further optimize its size parameters, save materials, and further reduce the cost of photovoltaic systems.


Solar Ground Mounting System


The loads acting on the foundation of the photovoltaic module mount mainly include: self-weight (dead load) of the mount and photovoltaic modules, wind load, snow load, temperature load and earthquake load. The controlling effect is mainly wind load, so the foundation design should ensure the stability of the foundation under the wind load. No damage occurs.


So, what are the types of ground photovoltaic mounting system foundations and flat roof photovoltaic mounts foundations? What are their characteristics?


Roof photovoltaic mounting foundation

Bored cast-in-situ pile foundation: It is more convenient to form holes, and the top elevation of the foundation can be adjusted according to the terrain. The top elevation is easy to control, the amount of concrete reinforcement is small, the amount of excavation is small, the construction is fast, and the damage to the original vegetation is small. However, there are on-site hole forming and pouring of concrete, which are suitable for general filling, cohesive soil, silt, sandy soil, etc.

Steel spiral foundation: it is easy to form holes, the elevation of the top surface can be adjusted according to the terrain, and it is not affected by groundwater. It can be constructed as usual under winter weather conditions, with fast construction, flexible elevation adjustment, little damage to the natural environment, and no filling and excavation works. The damage to the original vegetation is small, and field leveling is not required. Suitable for deserts, grasslands, tidal flats, next door, frozen soil, etc. However, the steel used is relatively large, and it is not suitable for strong corrosive foundations and rock foundations.


Independent foundation: the strongest ability to resist water load, resist flood and wind. The amount of reinforced concrete required is the largest, a lot of labor, a large amount of earthwork excavation and backfilling, a long construction period, and great damage to the environment. It is rarely used in photovoltaic projects.


Reinforced concrete strip foundation: This type of foundation is mostly used in the foundation with poor bearing capacity, suitable for flat uniaxial tracking photovoltaic mounts in areas with relatively flat sites and low groundwater levels, and with high requirements for uneven settlement.


Prefabricated pile foundation: Prestressed concrete pipe piles with a diameter of about 300mm or square piles with a cross-sectional size of about 200*200 are driven into the soil, and steel plates or bolts are reserved on the top to connect with the front and rear columns of the upper mount. The depth is generally less than 3 meters. Relatively simple and fast.


Bored cast-in-place pile foundation: The cost is low, but the requirements for the soil layer are high. It is suitable for silty soil with a certain degree of density or plastic and hard plastic silty clay. It is not suitable for loose sandy soil layers. Harder pebbles or gravel may have problems forming holes less easily.

 Steel screw pile foundation: special machinery is used to screw it into the soil, the construction speed is fast, no site leveling is required, no earthwork and no concrete, and the vegetation in the site is protected to the greatest extent. The height of the mount can be adjusted according to the terrain, and the screw pile can be reused.


Ground photovoltaic support foundation


Flat roof photovoltaic mounts foundation

Cement counterweight method: pouring cement piers on the cement roof, which is a common installation method, has the advantages of being stable and does not damage the roof waterproofing.


Prefabricated cement counterweight: compared with the production of cement piers, it saves time and saves cement embedded parts
