Conversion of wind’s turbine & electricity
The document discusses wind turbines and how they work. It notes that there are four main parts of a wind turbine: the base, tower, nacelle, and rotor. Wind energy is converted to mechanical energy through the rotation of the turbine's rotor which spins a shaft connected to a generator to produce electricity. There are two types of wind turbines: utility-scale turbines for large-scale electricity production and single small turbines for homes, farms, or small businesses. The document provides references on wind turbines and wind energy.
Alternate sources of energy
This document discusses various alternative sources of energy, including solar energy which can be used for agriculture, transport, lighting, heating water, cooking, water treatment, and electricity production. It also describes wind energy and how windmills work to convert kinetic energy from wind into electrical energy, with India being the 5th largest producer. Additionally, it covers nuclear energy from fission reactions and the risks of radiation. Bio-energy from biomass, biogas, and methane is discussed. Other alternative sources mentioned include geo-thermal, tidal, and hydel energies.
Energies and electricity
This document discusses different types of energies and electricity. It defines primary energy as energy that comes directly from natural sources like the sun, earth, or moon. Secondary energy is energy that comes from transforming primary energy into a more usable form, like electricity. Renewable energies come from sources that never run out, like solar, wind, water, and geothermal, while non-renewable energies like coal, natural gas, and oil could eventually run out. The document also outlines how electricity is generated from primary energies and transported through domestic circuits to power appliances.
Analysis hortatory text advantage and disadvantage of nuclear power
The document discusses the advantages and disadvantages of nuclear power. It notes that nuclear power produces large amounts of energy from small amounts of uranium and does not produce pollution, but that nuclear accidents can be major disasters and nuclear waste must be sealed away for many years. The document also states that while nuclear power provided 11% of the world's energy in the past, it is also very dangerous if not operated safely.
Renewable energy sources
The document discusses various renewable energy sources including solar, wind, tidal, geothermal, hydrological/hydroelectric power, and biomass. It provides a brief overview of each source, noting advantages such as potentially infinite energy supplies, and disadvantages like high costs of implementation and environmental impacts. Renewable energy sources are defined as those that quickly replenish themselves and can be used repeatedly.
neft
Alternative energy sources include hydroelectricity, wind energy, solar energy, and natural gas. These sources are renewable, clean and do not negatively impact the environment like traditional energy sources. Solar power generates electricity from sunlight using photovoltaic cells. It is a renewable source that produces no emissions but the initial setup of solar power stations can be expensive. Hydroelectric power harnesses the kinetic energy of moving water and is a reliable renewable source, though building dams can displace people and impact the environment. Wind turbines convert the kinetic energy of wind into electricity through rotation.

BUILDING AN EFFICIENT SOLAR CHARGER AND COMPARING ITS CHARGING SPEEDS WITH A ...
Abstract of the Research Paper
Energy sources using exhaustible energy at its input are being discouraged because they cause significant damage to the environment and human beings. Solar energy is considered one among the clean and green energy sources because it takes sunlight as its input which is a renewable energy source. There are many places in the world where electricity is not constant or not available. There are also cases where solar energy is neglected by people simply because of a lack of knowledge of its efficiency, and it is basically considered non-efficient. The purpose of this research is to build a solar charger, test its workability, and compare its efficiency with a regular wall charger to provide information for it to be used by both rural and urban people. Both quantitative and qualitative approaches were used appropriately, and most efficient circuit parts and appropriate testers were used in this research study to achieve the objectives. It was found that the solar charger was almost as efficient as a regular wall charger. There were some factors which decrease the efficiency of the solar charger which may be analyzed by future researchers on this concept. In conclusion, after being found that a solar charger is as efficient as a regular wall charger, its use must be encouraged by both rural and urban people.
