Nuclear energy Everything around us is made up of tiny objects called atoms. Most of the mass of each atom is concentrated in the center (which is called the nucleus), and the rest of the mass is in the cloud of electrons surrounding the nucleus. Protons and neutrons are subatomic particles that comprise … Read more
Solar Energy : Source, Solar heating devices, solar cooker solar cell Sunlight is Earth’s most abundant energy source and is delivered free of charge. Indeed, the energy from sunlight reaching the land surface of the earth is thousands of times greater than the world’s current total annual consumption of energy. Yet harnessing sunlight’s energy … Read more
Civilian and military uses of Nuclear energy Civilian uses Plant mutation breeding Plant mutation breeding is the process of exposing the seeds or cuttings of a given plant to radiation, such as gamma rays, to cause mutations. The irradiated material is then cultivated to generate a plantlet. Plantlets are selected and multiplied if … Read more
Conventional and Non Conventional Sources of Energy Main Sources of Energy: The sources of energy are of following types: 1. Conventional Sources of Energy: These sources of energy are also called non renewable sources. These sources of energy are in limited quantity except hydro-electric power. (a) Coal and … Read more
Sources of Energy: Conventional and Nonconventional Sources – Energy is one of the most important component of economic infrastructure. It is the basic input required to sustain economic growth. There is direct relation between the level of economic development and per capita energy consumption. Simply speaking more developed a country, higher is the per capita … Read more
Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth’s surface, and rotation of the earth. Mountains, bodies of water, and vegetation all influence wind flow patterns. Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor. The rotor turns the drive shaft, which … Read more

There is direct relation between the level of economic development and per capita energy consumption. Two Main Sources of Energy: … Read more
Energy security Energy security can be defined as “the uninterrupted availability of energy sources at an affordable price”. Energy security has many dimensions: long-term energy security mainly deals with timely investments to supply energy in line with economic developments and sustainable environmental needs. Short-term energy security focuses on the ability of the energy … Read more
