A SUSTAINABLE FUTURE WITH RENEWABLE ENERGIES

Since our inception in 2019, Nara Solar’s core business has been, and continues to be, the creation and development of renewable energy and large-scale solar projects. As a company, our main objective is to develop solar assets that meet a high cross-cutting quality standard, in order to provide viable renewable energy projects that comply with all current regulations and legislation and also have a positive impact on society and the environment.

THE POSITIVE IMPACT OF SOLAR ENERGY ON THE ENVIRONMENT AND SOCIETY

Renewable energies are one of the main ways to combat climate change and reduce the carbon footprint, an issue that has become very important in recent years. The percentage of renewable energy use in our country is increasing and we are gradually moving from using non-renewable and polluting resources as the main source of energy to clean ones.

Solar energy, for example, is one of the main sources of clean and renewable energy that has a positive impact on the environment, as it is the least polluting: it does not produce CO2 when generating energy, solar panel systems do not make noise, it does not need water to produce energy and it does not produce any type of waste.

Continuing with the advantages that solar energy brings to the environment, we can mention that solar panels are sustainable. They are mainly made of silicon, a material obtained from sand, which can be found in abundance in nature. In addition, photovoltaic modules can be recycled at a rate of up to 90%.

And what impact does this energy have on society?

  • It generates a large number of jobs that can range from the manufacturing phase, installation… to the marketing and sales team.
  • It has a positive effect on health, as it does not pollute the air we breathe.
  • It has capacity and access to all geographical areas, improving the well-being and standard of living in different regions.

At Nara Solar we are committed to solar energy, developing photovoltaic projects with maximum technical efficiency and profitability, generating a positive social and environmental impact.

POLLUTION STICKERS

Vehicles and many means of transport produce large quantities of toxins in the atmosphere that affect air quality and climate change. To solve these problems, in 2016 the DGT created stickers that indicate whether vehicles are more or less polluting.

WHAT ARE THEY? HOW MANY STICKERS ARE THERE?

There are four environmental labels that were created in the National Plan for Air Quality and Atmospheric Protection 2013-2016 (Air Plan) which states that both particulate matter and nitrogen dioxide (NO2) are mainly emitted by road traffic in large cities and proposes the classification of vehicles according to the levels of pollution they emit. What is the purpose of these labels? To positively differentiate the most environmentally friendly vehicles.

Which car corresponds to which label?

  • Blue, zero emissions: identifies the least polluting or most environmentally friendly vehicles such as electric and plug-in hybrids. Drivers with this type of vehicle have total freedom of movement in cities, with no access restrictions and in some cases you can even park for free.
  • Green and blue, eco label: this category is for plug-in hybrids with a range of less than 40 km, non-plug-in hybrid vehicles (HEV), those using natural gas (CNG and LNG) or liquefied petroleum gas (LPG). Although these vehicles are considered clean, they may be affected by access and parking restrictions in cities during high pollution episodes depending on the scenario, but only in very exceptional cases.
  • Green, sticker C: corresponds to Euro 4, 5 and 6 petrol cars and Euro 6 diesel cars. Vehicles with this sticker, depending on the scenario (e.g. in the event of an alert situation), will be banned from driving and parking throughout the municipality. The restrictions are less permissive than in the previous categories.
  • Yellow, sticker B: these are the most polluting This category includes petrol cars and light vans registered from January 2000 and diesel cars from January 2006. Vehicles with more than 8 seats and goods vehicles, both petrol and diesel, registered from 2005 onwards. These are the ones that will encounter the most problems in terms of traffic and parking.

This sticker is affixed to the lower right-hand corner of the front windscreen on the inside, if available, or, failing that, anywhere visible on the vehicle. Failure to wear it can in some cases lead to fines. For example, in Madrid, since 8 October 2018, a new anti-pollution protocol has been in force, which means that not having this badge can lead to fines. And… How can you get them? New cars are given the environmental sticker directly at the time of purchase, but you can also buy them at the post office by presenting the vehicle’s registration certificate and paying a fee, or online from the website of the DGT.

FALSE MYTHS ABOUT RENEWABLE ENERGIES

Lately we have been hearing and talking about the term Renewable Energies as one of the main ways to tackle climate change and achieve the fight against decarbonisation. Since these are energies that use natural resources such as the sun, wind and water, they do not pollute our planet.

DEBUNKING 4 MYTHS ABOUT RENEWABLES

Despite all the benefits of renewable energies such as solar and wind, there are many who remain suspicious due to the many myths and hoaxes that are told about them. But… Are these truths true? We talk about it.

  1. They are more expensive than conventional energy.

This is one of the most repeated and heard, but the reality is that the opposite is true. Thanks to the increase in demand, as well as the advance of new technologies, the prices of renewable energies are increasingly lower. In fact, according to a study carried out by IRENA (International Renewable Energy Agency), solar and wind energy are among the cheapest in the world. Moreover, it should also be taken into account that these energies do not have as high maintenance costs as polluting energies.

  1. They are not able to cover all the needs of consumers and need the support of other energy sources.

Renewable energies are indigenous and this provides security of supply and economic development. As more and more governments and citizens are becoming aware of the climate crisis, demand for them has increased in recent years, and they are able to cover the needs of a country’s inhabitants.

  1. They are harmful to the environment (landscape and biodiversity).

The impact of renewables on the landscape is a subjective issue that is difficult to measure, as it is an aesthetic impact. In this case, only protected natural areas or areas inhabited by endangered species should be avoided. On the other hand, wind energy is accused of causing damage to wildlife, but this can be avoided with a prior study of the migratory routes that may be affected. On the basis of this study, it can be seen where to locate a wind farm or not.

  1. They pollute more than fossil fuels.

Renewable energy sources are 100% environmentally sustainable, do not produce emissions and are inexhaustible, so they do not pollute more than fossil fuels. Moreover, international experience has shown that their use is more beneficial and fairer for everyone.

There are undoubtedly many demonstrable and proven advantages of renewable energies. They are safe, environmentally friendly and the best option available to mankind to meet its energy needs.

HOW TO SAVE ON YOUR ENERGY BILL

Electricity is the only way for many appliances and devices to work at home, so the cost of energy is very important for the domestic economy. With winter approaching, many of you are thinking about what to do to avoid an exorbitant bill, so at Nara Solar we would like to give you some tips on how to save on your electricity bill.

TIPS ON HOW TO SAVE ON YOUR ELECTRICITY BILL

The first thing to bear in mind if you want to save on your electricity bill is to know how much power you have contracted. When we talk about contracted electrical power, we are referring to the unit that limits the number of appliances that can be connected to the mains at the same time without tripping the Power Control Switch (P.C.B.I.).

Another thing to bear in mind is whether the tariff we have contracted is with or without time discrimination. The difference between one and the other is that in the tariff with hourly discrimination the electricity consumption is billed according to the time of day, while the tariff without hourly discrimination is a type of tariff within the regulated electricity market that applies a single price for the kWh of electricity consumed at any time of the day during a full day.

What can you take into account in your day-to-day life to save on your electricity bill?

  • Avoid silent consumption: unplugging electronic devices that you are not using or disconnecting them directly can save up to 10% on your monthly bill.  Even if appliances are on “stand-by”, they are not completely switched off, so they continue to use energy. This also applies to items that are plugged into the mains when they are not in use, such as mobile phone chargers.
  • Use energy-saving or low-energy light bulbs: they save between 60% and 80% of electrical energy to produce the same light as a traditional light bulb. Using energy-saving bulbs can lead to significant savings at the end of the year.
  • Adjust the temperature: it is recommended that the average temperature in the home should be between 19 and 21 degrees in winter and between 24 and 26 degrees in summer. In addition, using a thermostat to programme the heating by zones and time slots can allow you to be comfortable at home without having to spend more on gas than necessary.
  • Use consumption apps: having energy-saving apps on your mobile phone can help you save electricity at home, as they tell you how much you are spending on electricity and gas, as well as having many other features.

Follow these tips to save on your electricity bill during the winter. If you want to know more information about why the price of electricity is going up, you can check it out on our blog.


TYPES OF STRUCTURES FOR PHOTOVOLTAIC PANELS

There are different types of structures for photovoltaic panel installations. Each of them adapts to different requirements and needs depending on different factors such as the terrain where they are installed or the weather conditions.

FIXED, MOBILE AND FLOATING STRUCTURES

As Spain is one of the European countries with the most hours of sunshine, photovoltaic solar energy is very useful and efficient.

There are different types of structures for the installation of photovoltaic panels, adapting to different requirements and needs depending on factors such as the terrain, the climate, the need to move the panels or not, etc. We can highlight the following structures:

Structures fixed to the ground:

This type of structure is the most common to see. They consist of installations using 41x41x2.5 mm thick strut rails that allow the installation of photovoltaic panels on top. To make this type of installation, a prior study must be carried out on the inclination and forces that the installation must withstand, taking into account the strength of the wind, weather conditions and the terrain on which it is to be installed. In this way, future damage to the installation can be avoided.

Mobile structures:

Mobile structures are the ones that have a higher cost and require a longer installation time, as well as more complex systems.  They are installed when there is a need to move the solar panels in order to capture sunlight. Depending on the location, nearby obstacles or metrological conditions, this type of installation may be necessary, otherwise the photovoltaic panels will not capture enough sunlight and we will be losing energy.

Floating structures:

These structures are one of the newest systems to be applied to photovoltaic panels. How are they installed? In the water by means of floating modules. With this system, large numbers of photovoltaic panels can be installed without the need to occupy agricultural land and take up space for other services. In addition, it generates benefits for the ecosystems in which they are installed, as they reduce the temperature of the water and, as a consequence, its evaporation.

Today, we can consider photovoltaics as one of the fundamental pillars of energy demand.

ENERGY TRENDS SHAPING 2022

In 2022, the most talked-about topics are green hydrogen, energy storage and sustainable mobility. Undoubtedly, the energy sector is becoming one of the most influential and important sectors worldwide as it is the engine of industries and companies.

THE ENERGY SECTOR IN A PROFOUND EVOLUTION

The energy sector is undergoing a profound evolution thanks to the advance of new technologies such as Artificial Intelligence, Big Data, Blockchain and the Internet of Things. These are some of the energy trends that are shaping 2022:

The decarbonisation of industry: the European Union aims to be climate neutral by 2050. In other words, it has set itself the goal of having an economy with zero net greenhouse gas emissions. The path towards decarbonisation will therefore mark the steps of the business community this year. A large number of companies and industries have already taken steps towards this transition process.

Energy prices will continue unstoppable: although it is difficult to predict how energy prices will behave over the course of a whole year, given the way they are evolving, everything points to the fact that energy costs will continue without respite for companies and households. Faced with this situation, renewable energies such as photovoltaic and wind power are presented as an opportunity to reduce energy costs and integrate more environmentally friendly generation models. A greater penetration of clean energies and the evolution of storage technologies will be some of the keys to controlling energy prices.

Sustainable mobility: mobility is plugged into sustainability and everything surrounding the electric vehicle becomes a protagonist. This means that both the mechanisms to provide flexibility to the grid and the development of recharging centres will have a major impact this year.

User integration is another challenge coming this year, and two-way vehicle-to-grid technology, better known as V2G, will be another challenge to enable electric vehicles to feed the energy they store in their batteries back into the grid. Here, green hydrogen plays a key role in reducing the sector’s dependence on combustion engines.

Green hydrogen is gaining prominence: green hydrogen plays an important role in the decarbonisation of sectors that are difficult to electrify. Spain, thanks to its renewable potential, can position itself as a European leader in this transition, thus guaranteeing a basis for developing new generation and demand technologies.

Cybersecurity: for this, blockchain technology offers a qualitative leap forward. It will make the electricity grid more flexible, dynamic and connected.  Its decentralised management mechanisms, secure and immutable recording of transactions and automation of operations can pave the way for managing the entire distributed and decentralised energy value chain in an optimal way.

Today, more than ever, we need breakthroughs in the energy sector that will enable us to meet the targets we have set ourselves and achieve the EU’s commitment to zero emissions by 2050.


excepción ibérica

WHAT IS THE IBERIAN EXCEPTION? WHAT IS ITS OBJECTIVE?

The current energy crisis due to the war in Ukraine is causing limitations in the electricity market. We have certainly had a complex year revolving around the price of energy, which is why the concept of the “Iberian exception” is all the talk of the town.

 THREE MONTHS OF THE IBERIAN EXCEPTION

The “Iberian exception” is a term used to describe the intervention mechanism in the electricity market with the aim of lowering the wholesale market price and thus reducing the electricity bill for households and companies. In this way, it is possible to go from having an OMIE of 190-200€/MWh to 120-140€/MWh.

In principle, the Iberian derogation will allow the gas price to be capped at 40€/MWh for the first six months after its application. In other words, from 15 June until 15 December, the gas price will not be able to exceed these prices to define the OMIE result.  And what happens after that? It will go up by 5 euros per month until it reaches the limit of 70 euros on 31 May 2023.

The gas cap will be financed on the one hand through congestion income/rents, which are those revenues derived from the cross-border electricity transition between Spain and France that are calculated as the total energy exchanged by the price difference between the two zones. On the other hand, through a quota imposed by the Iberian countries on those buyers who benefit from the implementation of the measure.

This month marks three months of the Iberian derogation, and… How has it affected the price of electricity? Since the mechanism was applied, the wholesale price of electricity in Spain has distanced itself from European levels, as the tendency in France, Italy and Germany is for the price per megawatt hour not to fall below 200 €/MWh, while in the Iberian market the price has only exceeded that level on one occasion (reaching 201.96 €/MWh).

To calculate the price, it is necessary to look at what electricity would have cost in the absence of the mechanism and according to estimates, the savings for Spanish consumers affected have been 16.54% (€54.51).

Although it is an effective measure, it is not enough according to experts and should be complemented with other measures to solve the energy problem.


THE WORLD'S LARGEST SOLAR ENERGY PRODUCERS

Solar energy is growing rapidly. It is produced by sunlight to generate electricity. It is inexhaustible and renewable and is obtained by means of solar panels. It is undoubtedly one of the great revolutions that will mark the future of the planet, as it is one of the cheapest ways of producing electricity.

THE COUNTRIES THAT PRODUCE THE MOST SOLAR ENERGY

At the top of the solar energy production ranking is China, which is the undisputed leader. Although the Asian country is still the world’s largest emitter of CO2, it is committed to solar energy not so much for the sake of the environment but because of the need to generate energy quickly as the economy grows and the demands of its citizens increase. In just two years, China has managed to double its solar capacity and this is also due to the fact that it is the world’s largest manufacturer of solar panels.

In second place in the ranking is the United States. Since 1983, when construction of the SEGS thermal power plant began, it has produced more than 17 million megawatt-hours (MWh). Undoubtedly, this country has the technology, the talent and the environmental conditions required for large-scale deployment of solar energy. In addition, the United States is home to many of the world’s largest solar installations, including Gemini, Poplar, Topaciom Desert Sunlight and Misae 2.

Leading the third position would be Japan, which has been at the forefront of solar energy technology since the late 1990s.  The Japanese government has prioritised solar energy, adapting its policies and offering subsidies and grants for installation, making panels more attractive and affordable. Japan continues to innovate in the sector with the goal of solar energy covering 10% of the country’s energy demand by 2050.

On the other hand, we have Germany, a country that has been one of the world’s leading generators of solar energy for several years. And what is its goal? That by 2050 the country should obtain at least 80% of its energy from renewable sources as part of its campaign to reduce carbon emissions.

Finally, in fifth place is India, which has set a goal of 450 GW of renewable energy capacity by 2030. According to the International Energy Agency (IEA), solar power is expected to account for 31% of the country’s energy mix by 2040. A very ambitious goal for the country! Since solar energy prices are particularly low in the country, the government is cancelling construction projects for several coal-fired power plants.

Turning to solar energy sources has never been as environmentally friendly and cost-effective as it is today.

THERMAL POLLUTION, CAUSES AND CONSEQUENCES

Thermal pollution is a process that changes the temperature of the environment in a detrimental way. This change in temperature can be reflected both upwards and downwards, negatively affecting the quality of air, water and living beings.

WHY IS IT CAUSED? WHAT ARE ITS CONSEQUENCES?

This type of pollution is less mentioned than others, but it is no less important, and many environmental organisations have already taken up the fight against thermal pollution.

Thermal pollution is caused by industrial activity, which introduces heat into the environment in an uncontrolled manner, for example:

  • The use of water as a cooling system: the main causes of this pollution are industrial and manufacturing plants. These plants obtain water from nearby sources to avoid overheating their machines, which they then discharge back to this source, but at a higher temperature. When this water is returned to its natural source, the temperature of that body of water increases significantly.
  • Deforestation and soil erosion: these factors increase the level or expose water bodies to sunlight, which causes them to heat up abnormally.
  • Natural causes: for example, volcanoes and geothermal activity can also have an impact on the warming of groundwater and oceanic waters, with major environmental impacts.

What are the consequences of thermal pollution?

  • Reduced oxygen levels in water: Warm water can retain lower amounts of dissolved oxygen than cold water, due to its excess internal energy. This makes the water less suitable for life, suffocating animal species.
  • Increased toxins: water from industries flowing into seas and rivers may contain toxins and these have an effect on the ecology of the area, causing more diseases to develop.
  • Mass migration: rising or falling temperatures can cause species to migrate to environments where conditions are more suitable, affecting organisms that depend on these species for their survival.

To act and fight against thermal pollution there are some solutions such as reinforcing ecological legislation, recycling water from industrial processes or implementing reforestation plans.
