Some important kinds of biomass are inferior wood, urban waste, bagasse, farm animal and human waste. It is used for operating water pumps for irrigation purposes. For producing electrical power from tidal energy, dams are built close to estuaries to make use of inward and outward water currents and surges. Dish solar cooker is a fast cooking device which can cook food for 10 to 15 people under sun. In India, hydroelectric power is generated by a number of multipurpose river valley projects e.
All India dung production is about 11. And what can be a better renewable resource than the sun? In fertilizer industry, almost all the energy requirements of the ammonia and urea plants are met with steam generated through high pressure waste heat- boilers. Geothermal plants have been associated with toxic emissions such as sulfur dioxide, silica and heavy metal deposits of mercury, arsenic and boron. The best option in front of us at present to tackle the problems posed by fossil fuels is the option of using alternative sources of energy. Wind turbine farms create noise pollution. An emerging technology may allow hydropower to be collected from the movement of water in pipes in a municipal water source.
Under Solar Thermal Programme, solar energy is directly obtained. The magma layer is pushed up due to some geological changes and get concentrated below the earth crust. There are about 330, 00 biogas plants in India. It occurs below the earth crust entrapped under rocky strata. These traditional energy sources consist primarily of coal, natural gas and oil. Geothermal Sites Tattapani Geothermal Fields, Chhattisgarh and Puga geothermal Fields, Jammu and Kashmir are the two geothermal sites which have the potential for development of power generation. What do you mean by nuclear energy? These risks and hazards, not to mention the insurance costs to cover them, might be too pricey for the project to be commercially viable under present technological standards.
Normally, the tidal range is quite small and so tidal energy can be developed only in a few places. In the process India has emerged a world leader in the development and deployment of gasifier technology and systems. When the supply is inconsistent and unreliable, large quantities of power might not be generated from non-conventional energy sources. Currently, some of the important and widely used non conventional sources of energy are tides, wind, solar geothermal heat, and biomass comprising animal waste, agricultural waste, and human body waste. Besides, it is a renewable and clean energy source. It is broadly utilized in domestic circles for preparing food and warming. Coal: Coal is a major conventional energy sources.
Nuclear reactors create toxic wastes that are harmful to living things, thus making storage, transport and disposal a serious challenge. Finally, I will conclude that solar energy is a viable resource in Africa. Solar cooking has been picking up fast with a number of households and institutions, especially those attracting large number of visitors, evincing interest in installing different solar cooking systems depending upon the number of persons for whom they have to prepare food every day. The payback period of biogas is around 2-3 years, rather in case of community and institutional Biogas plant is even less. The success of biogas technology has brought about a sort of Brown Revolution in rural India. The movement of air occurs both horizontally and vertically.
Bio Energy: This type of energy is obtained from organic matter. Consider hydropower dams during a drought. They form from decaying plant and animal material over hundreds of thousands to millions of years. A final point: annual global investment in renewable energy is now more than double that of fossil fuels and nuclear energy combined. Geothermal energy: The geothermal energy may be defined as the heat energy obtainable from hot rocks present inside the earth crust.
There are many technologies available for conversion of solar energy into solar power. Similarly, the technology for producing biomass briquettes from agricultural residues and forest litter at both household and industrial levels has been developed. India is blessed with abundance of sunlight, bio mass, wind, water which can serve as alternative to conventional sources of energy. And these cells are normally made by. This initiative had resulted in disseminating the solar thermal products in different parts of the country.
The crude petroleum after being refined and purified, are available as petrol, diesel, kerosene, lubricating oil, plastic etc. Therefore, this energy has a bright future. Which two main points are necessary for its working? The spectrum of renewable and non-conventional energy sources today covers solar energy, wind energy, biomass tidal ocean energy and geo-thermal energy. The water is made to pass through turbine to get out of the basin. Africa, has second largest population, estimated 1.
How charcoal is different from wood? Uses of Solar Cell : a Artificial satellites and space probes use solar cells as the main source of energy. . This energy is manifested in the hot springs. Plan to exploit this potential has been finalised. In practice relatively few land areas have significantly prevailing winds.
Biogas: Biogas is an important source of energy to meet energy, requirements of rural area. Extensive surveys are being conducted to develop geothermal energy for direct heat and power generation. In the form of photovoltaic power generating electricity by means of solar cells. Baggasse-based plants: Bagggasse is generated as a waste product in sugar mills. Bio-mass based energy: The organic matters originated from living organisms plants and animals like wood, cattle dung, sewage, agricultural wastes etc.
