Sustainable Energy

Sustainability and energy have always enjoyed what can only be called a tenuous relationship. In other words, achieving a balance between green technology and economic feasibility can be challenging on occasion. It is still a fact that sustainable energy represents one of the most viable solutions in order to effectively combat climate change and to provide a reliable source of power to a growing global population.

Still, sustainable energy represents a rather broad term. While often used as a catch phrase within political campaigns and when marketing specific products, what does sustainable energy actually involve? Considering the fact that up to 29 per cent of the global population now relies upon sustainable energy sources, we should address this question in greater detail.^[1] Let's first take a look at the basics of sustainable energy before discussing how the team at SFC Energy AG can help as well as any future hurdles that still may need to be overcome.

A Functional Definition of Sustainable Energy

Sustainable energy has been defined in many ways over the years. From a broad perspective, sustainable energies can be classified as any type of approaches that satisfy contemporary energy requirements without placing future generations at risk.^[2] In other words, the primary concept of sustainable energy involves assuring that vital resources will not be depleted over time. This is the very same reason why traditional substances such as coal are slowly being phased out; there are only finite amounts available.

Environmental friendly energy is yet another way to categorise this approach. Sustainable energy solutions are frequently associated with a more conscientious mindset in regard to their impacts upon natural ecosystems. Perhaps the most well-known example in recent times involves the necessity to combat the ongoing effects of climate change. This is the very same reason why advanced fuel cell technology has already begun to supplement and replace standard batteries and why solar power is becoming extremely popular within developed nations.

Is There a Difference Between Sustainable Energy and Renewable Energy?

Both of these terms are often used interchangeably and yet, there are some important disparities to mention. Let us take a closer look at how each is classified to appreciate the big picture. Here are some core tenets of renewable energy:^[3]

• This power is derived from natural sources that can be replenished in accordance with the needs of consumers.
• Examples include wind, photovoltaics, biomass, and hydropower.
• Perhaps most importantly, some sources of renewable energy are not sustainable (in terms of how they can be distributed or accessed).

Here are some primary principles of sustainable energy:

• Sustainable energy analyses the needs of future generations of consumers.
• A great deal of emphasis is placed upon logistics such as how sustainable energy is collected and distributed.

To simplify things further, we can view sustainable energy as any type of system that is able to replenish its resources at a faster rate than they are depleted. So, is renewable energy sustainable? Answering this question will depend on the type of energy itself. While solar power is entirely replenishable, other sources such as biomass might not be able to keep pace with large-scale consumer demand.

What are the Four Types of Sustainable Energy Systems?

Now that we have learned to appreciate the fundamental principles associated with sustainable energy, it is important to take a closer look at four common sustainable energy examples as well as the unique characteristics of each.

Solar Power

Solar power is often referred to as photovoltaics, as it harnesses the power of photons released from the sun in order to produce electricity. This strategy addresses many of the needs commonly linked with energy security and sustainability due to the fact that the sun provides a constant source of power. However, we need to keep in mind that not all regions of the earth may be able to leverage the associated benefits.

Wind Power

Offshore wind turbines have become commonplace throughout many regions of the world. In fact, more than seven per cent of global power generation can now be attributed to wind power.^[4] This technology has already made its presence known within certain regions such as the east coast of the United States and the North Sea. However, some have expressed opposition towards this type of sustainable energy due to its potential impacts upon the marine environment and navigational routes.

Geothermal Power

Iceland is perhaps one of the best examples of how geothermal power can offer a viable solution. An incredible 66 per cent of all properties now rely upon this form of sustainable energy and such a trend shows no signs of slowing down.^[5] Still, it should be mentioned that not all regions can tap into geothermal energy. While sustainable, the logistics can be quite challenging.

Hydropower

The most traditional form of hydropower comes in the form of a dam that is used to transform the mechanical energy of flowing water into electricity via the use of a turbine. Niagara Falls has used this type of sustainable energy for over 100 years and its benefits cannot be denied. Recent advancements involve tidal movements; an approach to sustainable energy that can be adopted across many regions.^[6]

The Sustainable Energy Options Offered by SFC Energy

The team at SFC Energy fully appreciates the advantages that sustainable energy can provide. This is why we have spent a great deal of time researching and developing the latest DMFC and hydrogen fuel cell technologies. Originally established in 2000, we have currently sold more than 65,000 units to an international customer base.

Hydrogen is a particularly potent form of sustainable energy for a handful of important reasons. First, it is readily available and the associated technology is well understood. Secondly, the products themselves have become cheaper over time; allowing average consumers to enjoy the advantages. Finally, the only byproducts of using hydrogen as a fuel are heat and water. This allows hydrogen to represent an environmentally friendly variant of sustainable energy.

What Obstacles Might Sustainable Energy Production Face?

There is little doubt that sustainable energy represents the technological wave of the future. Unfortunately, several hurdles may still need to be overcome. One involves practicality. For example, how can specific forms of sustainable energy and fuels be stored and distributed in an efficient manner? Certain types of infrastructure may need to be overhauled in order to accommodate for the presence of these alternative solutions.^[7]

Sustainable energy could also face regulatory issues on both national and international levels. This might make it difficult for companies to offer their services and in the same respect, for the customers to obtain the products themselves.

Market competition is yet another concern throughout the sustainable energy sector. Some traditional companies have been reluctant to adopt sustainable energy and as a result, green solutions could very well face an uphill battle.

Lastly, some consumers are still not convinced that sustainable energy will offer long-term benefits. Clarity, transparency and education should therefore represent critical components of any ongoing marketing campaign.

What Does the Future of Sustainable Energy Hold?

The good news is that sustainable energy is expected to enjoy a bright future. This is due in part to cutting-edge approaches such as the development of blue hydrogen (a form of low-carbon hydrogen that produces no carbon dioxide when burned) as a practical source of sustainable energy.^[8]

Another important takeaway point is that even large multinational companies associated with fossil fuels have begun to realise the ongoing impacts of climate change and implementing sustainable energy strategies (albeit begrudgingly at times). This also signifies that consumers are becoming more aware of their roles.

These are some of the very same reasons why the professionals at SFC Energy AG aim to remain well ahead of the sustainable energy curve.
