What is geothermal energy? Geothermal energy (GTE) is the energy present on Earth’s crust due to the heat energy inside the Earth. The terms “Geo” and “thermal” mean Earth and heat respectively, making geothermal meaning “heat from Earth” as a whole. The geothermal energy is renewable energy since this energy
What is a solar tracker? A solar tracker is a device that aligns the solar energy harvesting devices perpendicularly to the sun. These solar energy harvesting devices can be anything that extracts solar energy, but we will only discuss the solar panels and how solar tracker systems work for them.
What is a solar tree? A solar tree is a vertical structure (usually a pillar), made to support solar panels to collect solar energy and deliver electrical energy. The arrangement of solar panels on this pillar resembles the leaves of trees, and that is why this type of structure is
What are spray-on solar cells? The spray-on solar cells are an extension of perovskite solar cells (PSCs). In these solar cells, the active perovskite material is sprayed on a substrate that already has layers of cathode and electron transport layer (ETL). Further layers needed in the complete design of the
Perovskite solar cells A perovskite solar cell is a solar energy harvesting cell, just like other technologies of the solar cells. However, as its name suggests, perovskite solar cells have an active perovskite material whose structure of crystal resembles the crystal structure of calcium titanium oxide (CaTiO3 ). All perovskite
What is a windmill? A windmill is a device that harnesses wind energy by utilizing the kinetic energy of the wind and converts this energy into rotational kinetic energy, which is then used to grind grain and other crops. Although windmills can also be used for the generation of electricity,
What is an artificial leaf? Photosynthesis and its working Most of the scientific advancements and strides “Man” has made, come directly from observing and studying nature. It is as if nature presents the questions and contains the answers within itself, which are just needed to be explored. This fact can
Environmental degradation through Depletion of natural resources The depletion of natural resources is the process by which the natural resources found on earth, such as coal, oil, water, wood, are reduced due to their excessive utilization. This utilization of non-renewable natural resources causes environmental degradation. Environmental degradation is a secondary
Climate change The major factor disabling the human race from achieving sustainability is climate change. Climate change is the change in weather conditions that adversely affect the areas on earth locally or globally. Climate change is occurring mostly due to human activities that result in the release of greenhouse gases
