Wind Energy, Hydrogen Energy and Fuel Cells | Environment
Wind Energy
Wind, which is substantially air in motion, has kinetic energy by virtue the movement of large masses of air caused by differential heating of the atmosphere by the sun. At any given time, the amount of power contained in the wind energy is proportional to the wind speed at that instant in the context of wind energy production systems. This energy can utilize for performing mechanical…

Conventional Energy Sources and its Problem | Freestudy9
Introduction to Energy Sources
Energy can define as the capacity to do work. Work such as pushing or pulling product of force. Thus, energy sources abstract concept. Though power is present in some forms like mechanical, thermal, chemical, biological, which differ fundamentally from one another but together constitute the physical reality of our universe.
We cannot see it or feel it, even if we…

Thermal Pollution Effects and it's Causes | Environment Study
Thermal Pollution Effects and it’s Causes | Environment Study
Thermal Pollution
Thermal pollution refers to the degradation of water quality as a result of any process that changes the ambient water temperature.
A common cause of thermal pollution is the use of water as a coolant by power plants (thermal and nuclear) and industries.
The water used as a coolant returned to the water sources like rivers, lake, etc at a higher temperature.
So, let us see an…

Effects of Air Pollution on Human Health | Environment Study
Effects of Air Pollution on Human Health
Carbon monoxide (CO) and nitric oxide (NO) combine with haemoglobin to form carboxyhemoglobin (COHb) which reduces oxygen carrying capacity of blood. So, let’s dive into deep for effects of air pollution.
Oxides of nitrogen (NOX) and oxides of sulfur (SOX) cause irritation to eye, throat, and nose. They cause diseases like asthma and bronchitis.
