Energy has long served as a fundamental driver of the structure and evolution of human civilization across time. At its core, energy may be understood as the capacity to perform work that induces change within a system—whether in terms of temperature, form, or position.

Energy is governed by a fundamental principle: it is conserved and cannot be destroyed. Instead, energy can only be transferred or transformed from one form to another. For instance, when humans consume food and beverages, the body absorbs energy in the form of heat (calories), which is subsequently converted into the energy required to power bodily functions.

The utilization of energy dates back to prehistoric times, particularly through the use of fire as a source of heat, illumination, and cooking. This utilization expanded significantly during the Industrial Revolution through key innovations such as the steam engine and the development of electrical systems, supported by pioneering breakthroughs from figures like Nikola Tesla.

Today, the use of energy has reached a relatively advanced and complex stage, as evidenced by the harnessing of solar radiation, nuclear energy, and fossil fuels to power transportation systems and various industrial processes.

Despite what may be considered a “golden age” of energy utilization, not all forms of energy possess an inexhaustible supply. Entering the era of Industry 5.0, with the Earth experiencing increasing environmental degradation, natural changes, and geopolitical tensions, humanity is progressively confronted with energy scarcity.

In the first quarter of 2026, the closure of the Strait of Hormuz—one of the world’s most critical oil supply routes—significantly disrupted global energy security. This development has had far-reaching implications for distribution systems, inequality, and the economic burden experienced by industries and societies alike.

In response to these emerging challenges, a range of countermeasures has been implemented, including the adoption of Work From Home (WFH) policies and public campaigns encouraging electricity conservation to maintain supply stability. However, sustained innovation in renewable energy remains essential as a long-term solution.

While reducing energy consumption may serve as an effective short-term measure, a gradual and structured energy transition is indispensable for long-term sustainability.

Amid ongoing discourse surrounding energy limitations, research ecosystems and academic communities play a crucial role in addressing these challenges by generating solutions that support the transition toward renewable energy systems.

According to Belinda Ayuningtyas, S.T., M.T., a lecturer in Electrical Engineering at Dian Nusantara University, the transition to renewable energy currently represents one of the most effective strategies for maintaining energy cost stability while reducing societal dependence on non-renewable energy sources such as petroleum and fossil fuels. One of the strategies she proposes is the implementation of a smart grid system integrated with battery technology, which functions not only as an energy storage solution but also enhances the absorption and utilization of locally available energy sources, such as solar and wind power.

Moreover, enhanced energy literacy and the promotion of positive, research-based narratives surrounding renewable energy contribute significantly to encouraging public participation in the energy transition. With effective downstream implementation, it is expected that more equitable access and balanced opportunities can be realized for society at large.

As a vital source of life, energy continuously undergoes cycles of transformation, just as humanity—its primary user—must continuously seek innovation to ensure collective sustainability. Despite the imminent threat of energy scarcity, it is imperative to strengthen innovation, promote responsible energy use, and advance the study of renewable energy.

Interest in the development of electronics, electrical phenomena, and the optimization of energy utilization has become a central focus within the academic ecosystem of Electrical Engineering. The Electrical Engineering Study Program at Dian Nusantara University (UNDIRA) serves as a platform for cultivating these competencies.

Like stars that shine brilliantly across the vast expanse of space, energy embodies both beauty and necessity. As the energy crisis looms over nations, it calls for collective action. Together with the Electrical Engineering Program at Dian Nusantara University, let us develop sustainable solutions for the future.
