In the quest for a sustainable future, policymakers and environmentalists worldwide face the challenge of finding viable alternatives to fossil fuels. While renewable energy sources such as wind and solar have gained significant attention and should be the preferred solution, nuclear energy remains an option but a contentious topic.

The Sustainable Development Goals (SDGs) we’ll discuss in this article are:

• SDG 7 (Affordable and Clean Energy)
• SDG 8 (Decent Work and Economic Growth)
• SDG 9 (Industry, Innovation, and Infrastructure)
• SDG 11 on Sustainable Cities and Communities
• SDG 12 (Responsible Consumption and Production)
• SDG 13 (Climate Action)

However, with modern technological advancements, is it time to re-evaluate nuclear energy’s potential benefits in achieving the Sustainable Development Goals (SDGs) and fostering global prosperity? This piece explores the arguments favouring nuclear energy, evaluating its potential contributions towards a sustainable future.

Nuclear energy has long been a contested issue, with solid arguments. Proponents of nuclear energy claim that it is reliable and provides a steady electricity supply at low prices. At the same time, critics argue that the technology is unsafe and creates harmful waste.

Carbon Neutrality and Climate Change Mitigation

The urgency to combat climate change demands a swift transition from fossil fuels. Nuclear energy offers a significant advantage as a low-carbon energy source. Emitting virtually no greenhouse gases during operation provides a viable alternative to help meet climate change mitigation targets. By expanding nuclear power, countries can drastically reduce their carbon footprint, contributing to achieving SDG 13 (Climate Action) and supporting the Paris Agreement goals.

Nuclear power is considered a low-carbon energy source because nuclear power plants produce virtually no greenhouse gas emissions[1]. Unlike fossil fuels, which release large amounts of carbon dioxide into the atmosphere, nuclear power generation does not contribute directly to climate change. It can support efforts to reduce greenhouse gas emissions.

However, while nuclear power is low-carbon, it is distinct from renewable energy sources because it does not rely on constantly replenished resources. Renewable energy sources such as wind, solar, and hydroelectric power harness natural processes that are continuously available, like sunlight and wind[2]. In contrast, nuclear power relies on fuel, such as uranium, a finite resource that needs to be mined and processed. Renewable energy is now cheaper to construct and operate than other energy sources.

Additionally, the Sustainable Development Goals (SDG) 13 includes not only the reduction of greenhouse gas emissions but also the promotion of renewable energy. Although nuclear power does not emit greenhouse gases during operation, it is not considered a renewable energy source because it relies on the extraction and processing of uranium, which has limited availability. SDG 13 aims to achieve a transition towards renewable energy sources to mitigate climate change and reduce reliance on finite resources.

It is important to note that while nuclear power does not directly address the goals of advancing renewable energy, it can complement renewable energy sources in achieving SDG 13 targets. Nuclear power can provide a baseload capacity and continuous power supply, supporting the integration of intermittent renewable energy sources like wind and solar. This combination of nuclear and renewables can ensure a reliable and sustainable energy mix that reduces greenhouse gas emissions and advances the transition to a low-carbon future.

So, while nuclear power is considered low-carbon due to its minimal greenhouse gas emissions, it is distinct from renewable energy sources because it relies on finite resources.

Reliable and Continuous Power Generation

Unlike renewable energy sources that rely on intermittent weather conditions, nuclear energy provides a consistent and reliable power source. Base-load capacity is crucial for meeting the growing global energy demand and supporting the electrification of transportation and other sectors. Nuclear power plants can operate continuously for extended periods, ensuring a steady electricity supply to communities and supporting economic growth. Reliability in power generation is essential for achieving SDG 7 (Affordable and Clean Energy) and SDG 9 (Industry, Innovation, and Infrastructure).

Nuclear power plants can be built and operated according to high safety standards, minimising the risk of accidents. Nuclear energy is a reliable, low-carbon source of electricity, which helps mitigate climate change by reducing greenhouse gas emissions.

Sustainable Development and Economic Growth

Nuclear energy has the potential to drive sustainable development and economic growth. Constructing and operating nuclear power plants creates jobs, promotes local industries, and stimulates economic activity. Developing a robust nuclear industry also requires investments in education and research, fostering technological advancement and creating a skilled workforce. In this context, nuclear energy aligns with SDG 8 (Decent Work and Economic Growth).

Energy Efficiency and Land Use

Compared to many renewable energy sources, nuclear power plants require relatively small land areas, allowing more efficient land utilisation. This is particularly advantageous in densely populated regions where space is limited. By optimising land usage, nuclear energy supports sustainable urban planning, protects natural ecosystems, and contributes to SDG 11 (Sustainable Cities and Communities).

Public opinion on building nuclear power plants near homes can vary, but evidence suggests that support for nuclear energy has increased in recent years[3]. According to the National Nuclear Energy Public Opinion Survey conducted in 2022, there was a record-high public support for nuclear energy and building more nuclear power plants[3].

Studies have shown that communities hosting nuclear power plants can reap economic benefits, including higher home values than areas near fossil-fueled power plants[4]. This suggests that some individuals may be more accepting of nuclear power plants being built near their homes due to the potential economic advantages.

Various factors can influence public opinion, including concerns about safety and waste disposal[5]. Accidents like Three Mile Island and Chernobyl have raised concerns and led to past opposition to nuclear power plants [5]. Studies have found that acceptance of nuclear power plants can vary across different countries and contexts[6], and it is important to consider specific local factors and community preferences when evaluating public opposition.

Economic benefits associated with hosting nuclear power plants may also influence local opinions[4]. However, concerns about safety, waste disposal, and past accidents have sometimes led to opposition [5]. Various factors can influence public opinion, and it is important to consider specific local contexts when assessing opposition to nuclear power plants.

Technological Innovation and Safety

Safety concerns surrounding nuclear energy have often overshadowed discussions regarding its potential benefits. However, advances in reactor design and safety protocols have significantly improved the overall safety record of nuclear power plants. Cutting-edge technologies, such as passive safety systems and small modular reactors, offer enhanced resilience and minimise the risk of accidents. Furthermore, stringent regulatory oversight ensures the safe operation of nuclear facilities, aligning with SDG 9 (Industry, Innovation, and Infrastructure).

Waste Management

Critics of nuclear energy often raise concerns about radioactive waste. However, it is important to recognise that advances in waste management technologies and practices have significantly reduced the environmental impact. Modern nuclear reactors, such as Generation IV designs, offer enhanced waste management capabilities, reducing the volume and longevity of radioactive waste. Developing sustainable and secure waste disposal methods is vital in addressing these concerns and achieving SDG 12 (Responsible Consumption and Production).

Final Thoughts

Proponents of new nuclear power plants argue that they can contribute to achieving the Sustainable Development Goals (SDGs). They highlight that nuclear power is a low-carbon energy source, aligning with SDG 13 on Climate Action. It provides a reliable source of electricity, supporting SDG 7 on Affordable and Clean Energy and SDG 9 on Industry, Innovation, and Infrastructure.

Nuclear power plants can stimulate economic growth, create jobs, and promote local industries, thus contributing to SDG 8 on Decent Work and Economic Growth. Additionally, proponents note that the efficient land use of nuclear plants aligns with SDG 11 on Sustainable Cities and Communities. They emphasise the technological advancements and safety improvements in nuclear energy to address safety concerns, while waste management methods have evolved to align with SDG 12 on Responsible Consumption and Production.

On the other hand, opponents of new nuclear power plants raise concerns about safety, waste disposal, and the financial burden. They argue that nuclear accidents pose significant safety risks, as incidents like Chernobyl and Fukushima demonstrate. Waste disposal is another worry, as adequate long-term storage solutions have yet to be universally established.

The high upfront costs of constructing new nuclear power plants are also a concern, which could divert investments from other sustainable development initiatives. Additionally, opponents highlight the finite resource dependency of nuclear energy and the potential adverse environmental impacts of mining and processing resources. Public opposition, driven by safety concerns, waste issues, and environmental risks, further complicates the establishment of new nuclear power plants.

It is essential to consider these arguments and thoroughly evaluate the potential benefits and drawbacks when discussing the role of new nuclear power plants in achieving the SDGs. It’s easy to argue that we need new nuclear power plants to achieve the SDGs. However, it is also important to consider the potential drawbacks and risks associated with this form of energy production. As I mentioned in the introduction, my choice would be an investment in renewable energy before nuclear any day. However, powerful lobbies can profit from building large-scale nuclear and less constructing renewable projects.

Today, wind power influences the global transition toward sustainable and renewable energy sources. Its status as a key renewable energy technology is expected to grow in importance in the coming years. The potential of wind power lies in its ability to generate clean electricity, reduce greenhouse gas emissions and contribute to energy diversification. Now, it is one of the fastest-growing infrastructures in history.  

One of the primary advantages of wind power is its abundance. Wind is a limitless resource, available in varying degrees across the globe. Harnessing this power efficiently through wind turbines can provide ample electricity alongside other renewable energy sources to meet the power needs of homes, businesses, and, possibly, entire communities.  Following the Paris Climate Accords, international climate governance was organized around three pillars: mitigation, adaptation, and implementation. While fossil fuels will not disappear entirely from the energy portfolio, the global goal is diversifying into other sources. Wind and solar power are the go-to possibilities.

Energy Diversification is Key to Meeting Paris Climate Mandates

Necessity is the mother of invention.  While the Dutch sought to prevent flooding, Israel used wind turbines to pump water to arid communities.  Then in the 1980s, the Start-Up Nation installed its first experimental wind turbines. Wind energy plays a growing role in Israel’s renewable energy mix as the nation seeks to reduce reliance on fossil fuels as part of its commitment to net zero emissions by 2050.

Enter First Airborne – Combining the Power of Drone Technology with Monitoring Performance

Now the country is championing bio-convergence – marshaling its peoples’ skills across the sciences – to explore how to make wind power an efficient energy resource.  Perhaps one of the leading players on the world measurement scene is First Airborne.  Headquartered in a small, picturesque village in Central Israel, First Airborne has developed a first-in-class patented wind measurement sensor called Windborne™. The 60-gram instrument, shaped like a small rocket ship, may transform wind farm monitoring and performance.

Attached to a moveable drone, Windborne, moving from wind farm section to section, enables short-staffed wind farm operators to obtain precision wind measurements across large-scale facilities at an unmatched scale. This validated level of accuracy and coverage has never been recorded before, making Windborne a possible game-changer for the renewable energy industry. It is the only robotic device in the wind-power industry to take direct measurements rather than provide a model measurement.

The potential of wind power to complement existing forms of clean energy is vast.  But how much wind is available, and what direction should the turbines face? As the renewable energy industry grows, accurate wind measurement data across large wind farms become vital to this growth sector.  Experts predict wind power offers the most significant future for energy. They suggest that even hydrogen will be fueled by wind farms. Green hydrogen is created by wind/solar power, and to meet our carbon-zero targets, green electricity must be used to produce hydrogen.

Wind Farms are Growing Exponentially

In speaking to Medika Life, First Airborne Founder and CEO Boaz Peled reflected on the possibilities of alternative energy sources to reduce dependence on fossil fuels.  “The growth of wind power today is between eight and 12% annually. In the offshore sector, it could reach as much as 30% annually, and with what’s expected off the Eastern Coast of the United States, that growth could exceed even that optimistic estimate. That’s like owning 10 airports and building another every year.”

While initial investment costs for wind farms are significant, the operational costs are relatively low compared to fossil fuel-based power plants. But profitability is razor thin.  Economics remains one of the key obstacles to making the shift away from fossil fuels.  As technology advances and economies of scale are achieved, the cost of producing wind energy will continue to decrease, making it economically viable and competitive.

Peled says, “Solar and wind energy have infinite and abundant potential. But among the challenges is determining how operators go from managing 300 to 3000 wind turbines and doing that efficiently to ensuring a sustainable business model.”

Wind (and solar) power faces challenges that must be addressed to realize its fullest potential. One of the primary challenges is that wind is intermittent. The other is that it’s a rapidly growing energy sector with a limited talent pool to operate and maintain wind farms.  Large companies in the wind sector are operating their portfolios on low margins. Every failure has a substantial financial and confidence-loss impact. Every additional hire has a significant effect on successful operations. Efficiency guides the effective utilization of staff and the potential for greater societal and operational outcomes.

Addressing these issues through improved technology, proper planning, and community engagement is crucial to maximizing the positive impact of wind energy while minimizing the pitfalls.

Israel – Innovation Perfected By Necessity

Like Israel, many nations are pursuing on- and offshore wind energy development as a renewable energy strategy. Denmark, German, Netherlands, and the United Kingdom lead the way in Europe with operational offshore wind farms. In North America, the United States is making strides with efforts underway in the Atlantic Ocean.

But then there is the pressing challenge of maximizing the operational investment in equipment.  Wind turbines generate electricity only when wind speeds are sufficient, and this fluctuation requires backup power sources or energy storage systems to ensure a stable energy supply. Leaders in this ever-growing sector are asking critical questions about metrics: How do we know what the wind is? If I know what the wind is, do I know the value of my wind resource? Am I producing correctly or not?  Even how wind arms can are possible risks to birds and bats, leading to potential collisions with turbines. Proper site selection, direction and mitigation measures reduce these conservation concerns.

Technology advancements are crucial to tap the full potential of wind power. Ongoing research and development efforts aim to enhance turbine efficiency, increase capacity factors, and improve energy storage solutions. Additionally, advances in offshore wind power are expanding its reach into new areas, where winds tend to be stronger and more consistent.

On the Way to Dubai and COP28 – Wind Power Validated

“The earth has enough sun and wind to meet humanity’s energy consumption,” says Peled, who managed wind farms in Eastern Europe before returning to Israel to launch his company.  “Now, the prime business question is operational.  Are there enough solar panels – probably not. Currently, the rate of solar panel energy access is low – one megawatt-hour of solar power compared to one-third to half of the megawatt capacity of wind. Wind is more efficient as an energy source.  Real-time measurement is critical to shifting this industry with its great potential into a high-performance sector,” he adds.

Wind power offers a great future for diversified energy sources. Measuring wind power is crucial to secure its place as an effective solution.  Our dominant economic model is from extracting crude oil from the earth, but this chapter is coming to an orchestrated close.  As the world convenes soon in Dubai for COP28, calls for renewable and sustainable energy will grow louder. It’s not enough to suggest that wind is a sustainable alternative.  That must be proven.

Accurate measurements – amassing that data – will determine whether wind power will become a global priority and how nations and corporations assess farm site suitability, optimize turbine placement and evaluate energy output. Only accurate and validated data can enable that level of informed decision-making, planning, and, ultimately, the great potential of wind power as a renewable energy source.  This visit to First Airborne was a conversation with pioneers whose robotic engineering attention to detail will likely take the hot air out of wind’s significant renewable energy potential.
