In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so…

Historically, classical thermodynamics was developed during attempts to improve the efficiency of steam engines. Those investigations led to the well-known zeroth, first, and second laws of thermodynamics. Although these laws are presented independently, linkages between the zeroth and second laws have been pointed out in the physics teaching…

The preservation of natural water and electricity resources is essential for the development of smart cities. Indeed, water and electricity are highly dependent and must be analyzed together to improve the energy efficiency. This article is about the study of the integration of renewable energy and smart solutions in a water heating system. The…

In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global…

A significant amount of energy in the form of heat is lost in industrial processes once it is used in specific processes. Among different technologies, high-temperature heat pumps (HTHP) are a valuable method of recovering low-temperature waste heat in the industry in a very efficient way that can be activated using clean electricity. As a…

The continued and substantial increase in technological resources generates a new concept of education that utilizes online resources -- blended learning. Blended learning represents a combination of face-to-face experiences and online learning experiences. The advantage of this multiple-method approach is that it offers the opportunity to achieve…

The aim of this study was to design a digital game that imparts the concept of urban heat island effects to aid in environmental education. Within the play-time limits, gamers must be alert to signs of warning from the environment and keep the balance between economic growth and the temperature of the environment, so they can safely manage the…

In the New England region, where temperatures range from below 0 to over 100 degrees, heating and cooling can present a major opportunity to improve sustainability statistics of a campus. Overt changes such as improving windows come to mind, but recent advancements in boiler technology and strategies for working with the heat of the sun and the…
