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.


roof solar mounting  system


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

Garden solar PV mounting support and solar technology for agriculture and urban gardening

 

Garden solar PV mounting is just one of many innovations in agricultural solar technology. They provide urban residents with an automated but energy-efficient system that uses solar energy to power gardening equipment such as fountains and lightning.


In addition to their aesthetic value, they can take care not only of plants, but also other animals, such as pollinators. They can also power automatic bird feeders and insecticides.


Other garden solar technologies are aimed at larger farmers. For gardens or farms in remote areas with low power consumption, owning Garden solar PV mounting can make it very easy to automate the farm without being connected to the grid.


For example, if you raise livestock and want to keep them away from predators and thieves, you can use solar electric fences to protect them, which will provide additional protection for your herd. Others use solar water pumps, which allows them to ensure that the plants are adequately watered without having to water manually around the farm.


In winter, Winter garden solar panels used in the backyard can indeed provide sufficient heat for farm animals through solar air heaters. This is useful so that the farmer does not need to build additional insulation during the coldest months, nor does it put himself in danger by doing so.


Garden solar photovoltaic brackets can also illuminate certain areas of the yard to provide good visibility and easily deter intruders or pests.


All these technologies are possible without paying extra electricity bills. However, some of them will require a lot of money to build, especially if they require a lot of electricity. Agricultural modernization is a trend, but planning and investment must also be combined with actual garden conditions.

Can you put solar panels on a tile roof?

 

Solar panels can help your home become more energy efficient. so do you want to install solar panels on your roof? Installing solar on a tile roof requires a different approach, but it is possible. On a traditional asphalt roof, solar installation would simply require drilling into the roof and attaching your mounting brackets to the roof studs. The area around the Roof PV mounting brackets is then sealed and a flashing is installed to prevent water infiltration from the roof penetrations.


When a solar array is installed on your roof, it will be installed on one of the available solar racking systems. Depending on your roof type, how the mounts are installed will vary. Sometimes they will be put right into the roofing, other times they will be slipped under the roofing, and other times the roofing will have to be removed or replaced to install the mounts.

Once the mounts are installed, they will protrude out from the surface of the roof. Then, your installer will install the roof racking system for the panels to be mounted on. Once the racking system is installed, the panels will be secured to the racking system. Panels will have to be off the surface of the roof a bit so they don’t overheat and can produce at a top level. There are options for lower racking systems or a skirt for a more aesthetically pleasing array.

But more people choose low cost solar mounts and racking systems. There is always the option for a ground mounted system as well. In order to pull off a ground mounted system, you’d have to have a decent amount of area on your property that gets adequate sunlight. However, ground mounted systems, usually cost more than roof mounted systems.

What Are The Advantages of Solar Carport Mounting System?

 The solar carport mounting systems is very popular in developed countries. It mainly combines photovoltaic modules with the carport roof, which can not only meet the parking demand, but also provide power to the grid, increase income, and photovoltaic power generation is energy-saving and environmentally friendly. For large hospitals with limited land, building a green energy-saving solar carport is an effective solution.

Advantages of photovoltaic carport

Photovoltaic carport is a power generation system that uses solar cells to directly convert solar energy into electrical energy. Its main components are photovoltaic modules, brackets and inverters. Its advantages are high reliability, long service life, no environmental pollution, independent power generation and grid-connected operation, it is welcomed by households and enterprises, and its development prospects are broad.

Energy saving brings benefits at the same time

Solar carports came into being. Compared with installing photovoltaic modules on the roof of the carport, the combination of photovoltaic modules and the roof of the carport can save costs. It can not only realize all the functions of the traditional carport, but also generate electricity to bring benefits to car owners. It is generally supported by steel structure, which is simple and elegant, stylish and beautiful. It is a clean and environmentally friendly new energy source, effectively alleviating the social environment and energy pressure.

Distributed photovoltaic grid-connected system refers to a grid-connected power generation system that uses photovoltaic components to directly convert solar energy into electrical energy. The system is located near the user, and the generated electricity can be used locally. It can be connected to the grid at a voltage level of 10 kV and below. The total installed capacity of a single interconnection point (380V) does not exceed 6 MW, and the total installed capacity of a single interconnection point on the 220V user side. The capacity does not exceed 8 kilowatts.

The distributed photovoltaic power generation system can be installed in any place where there is sunlight, including the ground, the top of the building, the side elevation, and the balcony. Among them, it is widely used in schools, hospitals, shopping malls, villas, houses, factories, enterprises and institutions roofs, carports, bus stop signs; it can be installed on concrete, color steel plate and ceramic tile roofs.

The types of photovoltaic carports are divided into double carports and multiple carports. Most of them are modular in design, which can be used alone or in a variety of combinations. They are easy to expand, ranging from a few parking spaces to hundreds of parking spaces, and are highly flexible. If ordinary photovoltaic modules are used, the overall cost is lower. If the installed capacity is large, the income will be higher and the investment payback period will be short.

Choosing the Ideal Solar Panel Mounts

In this era when electricity costs are hitting record highs and may continue to rise, solar panels seem to be the best invention of mankind so far. However, solar panels require professional installation. If you do not install it correctly, it may become a burden for us. The solar panel support is very important. There are different types, in addition to cost, you must also consider their convenience and practicality.


There are currently three basic types of solar panel brackets on the market. Each type is developed for a specific type of photovoltaic system so that your panels can perform optimally.

Pole mounting is very popular because you only need to mount it on the top of the pole. It also has a track rod mount to make the panel follow the sun. This allows the solar device to absorb as much sunlight as possible during the day. This means you will be able to take full advantage of your photovoltaic system.


The roof ground mount is one of the most expensive mounts available. This is because they are specifically designed to hold large panels in place. They are very durable, no matter how big the panel is, they are guaranteed to support your panel. They are also called universal solar panel supports because they can be used to support different types of solar panels. You can choose to place it on the roof or on the ground. Either way, you should remember to make sure that the city allows this type of installation.

Flush mounts are the cheapest of all three mounts, and this is for good reason. They are only designed to support small photovoltaic systems, i.e. small panels. For those who want to install solar panels on their RVs or roofs, this is the ideal way to install solar panels. However, they are not as flexible as other mounts. In addition, you must consider the distance between the panel and the roof, because if it is installed too close to the surface, it will overheat very quickly.
