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
Importance of renewable energy resources Renewable energy are sources of clean, inexhaustible and increasingly competitive energy. They differ from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases – which cause climate change – nor polluting emissions. … Read more
Nuclear Energy Introduction Global energy demand continues to climb as the industrialized world’s energy use rises, millions pull themselves out of poverty in developing countries, and the world population expands. Thus, the debate over the energy supply of the future intensifies. This debate is complicated by ongoing global climate destabilization as a result … Read more

Conventional and New Source of Energy 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. Two Main Sources of Energy: … Read more
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
Uses and harms of nuclear energy Pros of Nuclear Energy Low Pollution: Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on … 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
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
