While many countries still back the wrong horse by supporting its growth with fossil fuels, some emerging countries bet on solar energy to build a sustainable economy just as well as a solution to energy deserts, especially in MENA and across the African continent.
Experts of alternative energy are calling Nigeria ‘the Saudi Arabia of renewable energy’. “Nigeria is the Saudi Arabia of renewable energy sources and, if properly utilized, Nigeria can realize its place in the world as a great power,” says economist and activist Jeremy Rifkin.
The rising African country has set a target of meeting 40 percent of its energy needs through renewable energy by 2020.
And in this effort, the country is relying on renewable solar power. With an average of 320 to 350 sunny days a year and vast tracks of deserts and farm land, Nigeria could easily generate 5,000 trillion KWh of solar energy, says Dr. Patrick Owelle, a Solar Energy Scholar and Research Fellow.
Expert predict that the country could install around 1,000 GW of solar generation — equivalent to 40 times the current peak power demand (about 25 GW) — using just 0.5 percent of its land.
Nigeria is not a single case in a world that is looking to reduce carbon footprint and foster alternative and renewable sources of power. And in the race, solar seems to be way ahead compared to other renewables.
However, in parts of the world where there is a rising demand for alternative power, as in Nigeria, there is also a debate about which solar technology would best suit a country or region.
While it is undeniable that solar energy is far more dependable than other forms of renewable energy, there is a rising debate whether to use concentrated solar power (CSP) or photovoltaic (PV) cells.
Dino Green, a Mechanical Engineer and a qualified accredited expert in certification of energy performance of buildings identifies the criteria that is generally debated while choosing the solar power technology to be used.
“Energy markets consider three main factors in deciding on power sources – cost of energy, ancillary services and power dispatch-ability on demand,” Greene says.
Experts say that a time is coming where there probably would be no competition between the two technologies and they may work together to increase solar energy penetration into the power industry.
The primary advantage of CSP technology is its ability to store solar energy. Silvio Marcacci Silvio, Principal at Marcacci Communications, a full-service clean energy and climate policy public relations company based in Oakland, CA, even defines CSP technology as “the technology that will save humanity”. “CSP could meet up to 7% of the world’s projected electricity needs in 2030, and 25% by 2050”, says Silvio.
Given all the strong arguments in favor CSP, the technology is criticized for taking up a large area to install it traditionally uses static parabolic mirrors to concentrate solar energy and then passing that down the line through a system of heated water. This heated water runs a turbine that produces electricity.
However with the advent of the Compact Linear Fresnel Reflector or CLFR technology, CSP can shed off the criticism of taking up space. French firm Sun CNIM is the pioneer in LFR technology for solar power generation and has successfully set up and operated a pilot project in France. The company says that the technology has moved beyond the pilot stage and Sun CNIM is now ready to commercialize the technology for large solar power projects.
Moreover, “Sun CNIM’s Fresnel technology and direct steam generation avoid the use of hazardous fluid such as thermal oils, making them the ‘cleanest’ technologies currently available,” says Sun CNIM in a statement.
Linear Fresnel is a line-focusing technology consisting of reflectors that track the sun in one axis and focus the beam radiation onto fluid-carrying receiver tubes.
IRENA’s 2012 CSP report (*) draws out the advantages of LFR technology over trough technology. The report states that main advantages of Fresnel CSP systems compared to troughs are that Linear Fresnel Collectors (LFCs) can use cheaper flat glass mirrors, which are a standard mass-produced commodity, and that they require less steel and concrete – as the metal support structure is lighter – which simplifies the assembly process and leads to cost reductions.
“According to the status of development in 2012, the parabolic trough seems to be at the end of its evolution because of the temperature limitations, complicated manufacturing and toxicity of the HTF. Therefore, I would prefer the Fresnel technology and the solar tower technology. Both use nearly flat mirrors which enable a higher share of local production”, says Dr.-Eng. Hani El Nokraschy, Co-Founder and Vice Chairman of the Supervisory Board of Desertec Foundation.
According to the French firm Sun CNIM, LFR is easily integrated into the grid and can be operated on isolated sites. “The technology is flexible where the component modules can be installed in accordance with capacity requirements and can be act as a hybrid to other alternative power sources like biomass, fossil fuel or methanization plants, etc,” says Sun CNIM communiqué.
Fresnel may give an additional advantage because of shadowing the ground. This enables planting under the mirror roof protecting the plants from the burning sunrays and thus saving irrigation water”, Dr. Nokraschy says.
Another advantage of the LFR technology is the reduced optical losses and less mirror-glass breakage since the wind loads on LFCs are smaller according to the French innovation technology firm Sun CNIM.
Moreover, the mirror surface per receiver is higher in the LFC than in parabolic trough collector, which is important given that the receiver is the most expensive component in both technologies.
“Until recently, linear Fresnel plants were mainly pilot projects. But with remarkable advancements, the technology is quickly gaining operational parity with the parabolic trough, and the world’s largest Fresnel power plant has already started operation in Spain,” says Heba Hashem, a technology expert based in UAE.
With the debate over choice of technology for solar energy nearly over, researchers and businesses are now concentrating on ways and means to develop technologies that can better the storage of solar power. This is considered to be the next big step in solar power attaining maturity.
Redefining marine recycling through painting and sculpture
Frutos María Martínez, a self-taught visual artist, has been rescuing waste from the ocean’s waters for decades, turning it into beautiful and elegant artwork. Finishing his first painting and sculpture pieces at just fourteen, Frutos has spent his entire life guided by his passion for art. Becoming a professional artist in the mid-1980s after working at car dealerships, Frutos used his skills and expertise with metal to create sculptures and paintings, inspired by the materials he found along the Mediterranean Coast.
In his pieces, Frutos combines numerous medias to create sculptures, paintings, and collages. As part of his process, María spends time exploring the beaches and waters of Alicante, a Mediterranean city along the southeastern coast of Spain and his home since 1985.
Here, he has found all sorts of materials that have gone on to become pieces in his collections. Steel, iron, wood, nets, and textiles, among other objects, that Frutos salvaged from the ocean can all be found in his art.
By reusing and recycling these found objects, the artist is able to give new life to abandoned and forgotten waste. María recognizes the environmental issues we are facing at a global level, and his art seeks to raise awareness of these challenges. As his materials are pulled straight from the Mediterranean Sea, he is especially invested in taking care of marine life and our oceans. With each item the artist salvages from the ocean, one less piece of waste is polluting the waters.
Once the flotsam is collected, Frutos returns to his workshop where he creates works of art in different forms. While other artists may send their work to be fabricated by others, María could not imagine his pieces being created in a place other than his studio. Here, he uses his innate skills with metal and machinery to forge and construct works of beauty. His sculptures follow hard lines, both straight and curved, and his paintings exude color. When making his collages, he takes his found mixed media and creates new stories. He adds paint to wood that was floating in the sea or combines various materials together, reimagining a life for objects that were once trash.
With a true passion for his work, he creates through intuition. He explains that there is a moment when his art becomes completely emotional and personal, “each piece is imbued with my experiences and emotion, all lumped together, all conveyed by means of materials, technique, design and imagination.” The works his hands awaken and renew are the convergence of his mastery and his spirit, bringing new life to discarded objects.These fascinating pieces have been shown in numerous exhibitions, most recently at the Museum of the University of Alicante. There, the artist presented Acero y pecios del mar (Steel and Sea Wrecks), where two collections were displayed jointly, one offering sculptures focused on steel as a material and the other called Nueva Vida, or New Life, a collection whose pieces were created by recycling materials salvaged from sea wreckage. With this collection, he introduced a new layer into his work, adding an element of chaos and destruction to the backstories of his materials.
An earlier exhibition, Janus, displayed over 40 of Frutos’ sculptures on the University of Alicante’s campus. This exhibit, named for the Roman god of doors, gates and transitions, was influenced by the duality of life, of beginnings and ends, and of old and new. While his finished pieces reflect this duality, the materials used to create them manifest this theme through their first death being revived into new life, a tangible and concrete example of the contrasting polarity he was inspired by.
As with his sculpture-centered exhibitions, his shows highlighting his paintings are full of found materials. Pieces that Frutos creates hang with the weight of rescued and recycled materials, such as rusty iron, steel, and wood. This media has been taken from the ocean and included in his art, conjoining with resin, sands, and paint in bold and striking colors.
Frutos María’s ability to not only find new meaning in recycled and salvaged objects, but to clean up the oceans and make the environment less polluted, translate through his moving pieces of artwork, and because of this, he has made a name for himself in the art world.
Wind energy, the best way to invest into renewable energies
Over the last few years, wind energy has become the type of energy everyone can not stop talking about. This type of energy brings lots of benefits into the table when compared to more traditional sources of energy, like the energy proceeding from radiation or charcoal. Wind energy is cheap to produce, the most efficient renewable energy, and, most importantly, it is an ecological sensitive alternative.
Why should you invest in wind energy?
Wind energy is the energy of tomorrow. This type of energy made their big appearance during the XX century, when wind turbines would be used to bring energy to areas located far from the electricity grid, such as isolated farms, houses or factories.
During the XXI century, wind energy’s popularity kept on rising. Wind energy is as cheap to produce as traditional sources of energy, like radiation or charcoal burning, while falling into the category of renewable energies. This made wind energy become a top contender in the energy industry.
The wind industry’s future looks to be brighter than ever. The current generation is pretty aware of pollution and the effect it has on climate change. This has caused that governments all around the world start promoting new legislations and campaigns promoting renewable energy and, since wind energy is the most efficient type of renewable energy, it is expected that it will become the main source of energy by 2030. Now is the best moment to jump into the wind energy trend!
Making sure you set up an efficient wind farm
As it has been previously stated, wind energy is definitely an option you should consider if you are looking to power up any of your properties or business. However, setting up a wind farm isn’t a small investment, therefore, before starting this process we need to gather all the information we can about its viability. That is why we can not stop recommending that you consult with professional companies like Vortex FDC.
Vortex FDC is a company that has made a name for itself in the wind industry sector. Vortex assists their customers with all the information regarding wind resource they could need.
For example, an important factor we need to consider before setting our wind farm is the terrain. Not all terrains are appropriate to locate a wind farm, therefore, the terrain would need to be assessed before an installation that could result in a waste of assets if the terrain is not appropriate for it. Vortex FDC helps their customers evaluate where the wind farm is going to be placed, and providing information about the wind to choose the type of turbines that would yield better results in that area. Factors like the type of wind (extreme winds, turbulences, etc) or the temperature need to be taken into account when deciding which type of turbine would be more suitable for our wind farm. For example, if we plan to build a wind farm in an area that gets freezing and snowy in winter, we would need to get a turbine system that is cold resistant.
Vortex FDC runs a numerical weather model to feature all the variables that could affect the production levels of your wind farm, regardless of it being situated off-shore or in-shore. Thanks to their always up-to-date technology, you will be able to avoid unpleasant surprises regarding the energy production of your wind farm.
Overall, opting to use wind energy is an amazing idea that will benefit not only our budget, but also the planet. But, in order to do so, we need to make sure that wind farms are viable, and for that, we need to rely on professionals like Vortex FDC.
Saving the Planet? It Is a Local Issue
When we get caught up in common environmental issues, we start to think that it’s a bigger problem, that is down to centralised areas and big cities. And while urban areas are expanding, the route to sustainability as a solution comes from an approach beyond urbanism. Because urban areas bear the brunt because they have more CO2 emissions and larger carbon footprints, the thing to note in this respect that saving the planet is not necessarily a large-scale issue. In fact, it is a local issue.
The largest cities require urban developments, and this is a part of modern life. But when we go back to the 1990s, when sustainable city initiatives began emerging, we can see where the argument for the compact city began. This can have a positive impact on sustainability in a variety of ways but also improves greenhouse gas emissions. But this is where smaller communities can become invaluable.
Smaller communities have more power in many respects. From the perspective of local councils, it can be easier to incorporate an initiative that benefits the community, rather than having to go all the way to Westminster. Now, it can be easier to sign up for a local initiative, such as a solar community, rather than having to get permission from a higher power. And from the perspective of a community, it is far more controllable.
Saving the planet in an urban sense is about changing the infrastructure, which can take years, if not decades. However, smaller communities are able to utilise the location for the benefit of their immediate surroundings. This is something very important to note. Whenever you want to make a significant impact, be it in charity, or in the environment, it starts at home. As saving the planet is a local issue in this respect, it’s far easier to communicate the message. Smaller communities are in close contact. This means the message is easily spread. Throw into the mix community meetings, and how businesses look to develop on local issues, rather than spearheading initiatives overseas or in big cities, and it provides a tactical methodology to help on a small scale.
When you combine this with the fact that smaller organisations such as schools, naturally have a lower carbon footprint, this is the perfect opportunity to teach the younger generations how they can positively impact the world. Saving the planet is a local issue. We have to remember that if we are to make any impact, we have to look after our own. That’s not to say that we shouldn’t rely on large organisations or big cities to do the job, but if you want to do something right, do it yourself.
Saving the planet is something that we can control from our own home. From the practices that we preach to the examples we set, saving the planet is about keeping it close to home before you start to spread yourself far and wide. If every small town started to look after its own carbon emissions, this would pay for the country, and the world, several times over.
