What are Energy Resources ?

Primary energy resources are those that are found in nature and mostly converted into secondary resources in industrial utilities. For example, Coal, Oil and Gas (primary energy resources) are converted into steam and electricity (secondary resources of energy) for various applications.
The principal energy resources on our plants are the fossil fuels like coals, oil, natural gas, biomass (such as wood, agricultural waste, etc.), water, wind and nuclear energy. Some uncommon energy resources include geothermal and tidal energy.

These energy resources are usually classified as:-
  • Primary and Secondary Resources
  • Renewable and Non-Renewable Resources
  • Commercial and Non-Commercial Resources

                                                      1). Primary and Secondary Resources:-

Primary energy resources are those that are found in nature and mostly converted into secondary resources in industrial utilities. For example, Coal, Oil and Gas (primary energy resources) are converted into steam and electricity (secondary resources of energy) for various applications.



The energy resources such as coal, oil and gas cannot be replenished within a reasonable time span and are likely to be depleted with time. They are often referred to as fossil fuels as they are found underground. They have formed over millions of years, but the rate they consumed is much higher than they formed. They are practically non-renewable resources. Their supplies are limited.


On the other hydro energy, wind energy, biomass energy, solar energy, tidal and geothermal energy are perpetual sources as they do not exhaust. All these sources are dependent upon sun dependent and they will continue to exist as long as the sun lasts. They are identified as renewable. They are better termed as conventional or alternative energy sources. So these resources will not be depleted.

                                                    3). Commercial and Non-Commercial Resources:-

The energy resources that are available in the market for a definite price are known as commercial energy resources. These include coal, oil, natural gas, electricity and refined petroleum products. There are certain energy resources that not available in the commercial market for a price. These are called non-commercial resources.
For example cow dung, agricultural wastes, solar energy for drying food products, animal power for transport, threshing, lifting etc. are not bought or sold at a price. These are traditional sources.

SOLAR Energy

The visible and near visible (Ultra-Violet and near Infrared) electromagnetic radiation that is emitted by the Sun is termed as Solar Radiation . The solar radiation has a spectral or wavelength, distribution that corresponds to different energy levels, short wavelength radiation has a higher energy than long wave length radiation. These solar radiation convert into useful forms of energy such as "heat and electricity", using a variety of technologies. The technical feasibility and economical operation of these technologies at a specific location depends on the available solar radiation or solar resource. Photovoltaic Effect :- Photo-voltaics are the technology for conversion of solar radiation (sunlight) directly into electricity. A photo-voltaic cell also called a PV or a solar cell is the device used for this purpose. The PV technology has  emerged as a promising technology to generate electricity for small applications like lighting and meeting other electric...

GREEN BUILDING

Green Building  Green Building does not refer to building which are green in colour or have been constructed with green parks around. It refers to a conscious practice of addressing the issue of resource conservation in an integrated and scientific manner. By definition, a green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building. Modern-day building have a tendency to use designs and materials which are resource-intensive and are quite often operate in isolation with the nature. Such buildings are very poor in energy efficiency and generate a lot of waste, adding to faster depletion of natural resources. Thus, building are seen today as one of the major pollutants to affect urban air quality and contribute to climate change. GREEN BUILDING A green building depletes very little of the natural resources during its constructi...

Gas Suppression System

Waterless  fire suppression systems work  by releasing  gas  or mixture of gasses into the air, generally with the aim of reducing the amount of oxygen in the air that feeds the flames. A clean agent fire suppression system begins with the deduction devices and ends with nozzles where the clean agent is released . From the deduction of the fire to the releasing of the agent, there are numerous devices to make the whole system run efficiently.  Components of GAS Suppression System:-   Below are some of the most common parts of a clean agent fire suppression system: Smoke Detectors : If a fire begins in the protected area, the smoke detector will detect the fire and send a signal to the control panel. Smoke detectors will usually sense the fire before it has had time to escalate. Optical Smoke Detector-Apollo Control Panel : The control panel is the brains of the system. When it receives a signal from the detectors, it then se...
