Wave Energy Converters: Sustainable Energy Source
Ocean waves contain tremendous energy. Experts estimate the theoretical annual energy potential of waves at the off-coasts of the United States to be as much as 2.64 trillion kilowatt-hours. Wave power has greater energy density than wind or solar. Researchers and engineers have developed various wave energy converter systems in the past few decades. This […]
How Can Future Smart Cities Power Themselves?
Smart-city journeys progress beyond technology deployment to a people-centered focus. It involves integrating Internet of Things (IoT) technologies such as sensors, AI, or 5G technology with existing infrastructure to power various hardware such as urban photovoltaic window coatings and glass, self-powered multifunctional windows, or electricity-generating roads, solar paths, bus and vehicle charging shelters, and so […]
Advanced Thermal Energy Storage for Energy Supply
Thermal Energy Storage (TES) is an energy storage method that can help balance energy demand and supply daily, weekly, and even seasonally. TES refers to heating or cooling a medium to use the energy when required later. The most common application of TES systems is integration with solar systems. Further, other application areas include storing […]
Achieving Sustainability with Offshore Wind Energy
To achieve sustainability, dependence on renewable energy sources should be increased. Wind is the second highest renewable energy generation source, behind only hydropower. Wind energy is divided into onshore and offshore systems. Offshore wind energy is more potent than onshore because of its environment-friendly attributes and high power generation capacity. According to data, the installed […]
Cobalt-free Batteries: The Need of the Future
Cobalt is a key component of lithium-ion batteries in many consumer electronics and electric vehicles. The demand for these batteries is increasing as the world moves towards sustainable energy sources. However, the extraction and processing of cobalt are fraught with ethical and environmental risks. Hence, the need for cobalt-free batteries is desperate. Fortunately, researchers are […]
Marine Oil Spill Clean-up Technologies
Oil spills have been recorded as a serious environmental threat. Increased deep-sea oil production and exploration, and oil transportation over the seas are the major reasons for oil spillage. Spilled oil must be removed from the water or the surface to protect the water and the environment. Marine oil combat is carried out to protect […]
Solar Panels Recycling: Demand and Benefits
With the rapid increase in the world’s population, meeting the need for electricity has been a major challenge and is mostly met by fossil fuels. Although these fossil fuels have many upsides, there are some considerable downsides as well, including increased greenhouse gas emissions, droughts, heat waves, rising sea levels, and more focus on renewable […]
E-Waste Recycling: Challenges and Country Wide Strategies
Every year, around 40 to 50 million tons of E-waste is generated, which accounts for 3-4% of total global waste. E-waste is any discarded electronic waste such as laptops, smartphones, televisions, electrical appliances, etc. This E-waste is harmful to the environment, and its exposure also harms humans. E-waste contains many hazardous substances, such as cadmium, […]
