produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat water — for use

Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service. For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services‚ it can result in

Wind Energy: Energy from Moving Air Abstract This paper contains the description of the process by which the wind is used to generate mechanical power or electricity‚ also describe the prospect and history of wind energy. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes‚ businesses‚ schools

discussed in Detail about Wind Energy and the production of electricity from moving vehicles. So first we defined Energy. Till Now we have studied that energy is the ability of a body to do work .it can also be defined as the ability of a body to bring some change is the energy of that body. Energy is very necessary for human beings; every thing in the universe possessed some energy. There are two main kinds of Energy 1. Kinetic Energy 2. potential Energy Kinetic energy is produced by the motion

Energy crisis in Pakistan Energy is the bloodline of a country’s economy. A continuous and sufficient energy `supply can ensure a healthy and progressive economy. Pakistan is unfortunate to face severe energy crisis in recent years. The parting gap between demand and supply is mounting with every year and it is pushing the country into dark ages. Worst part of this menace is the fact the installed capacity of electricity can not only fulfill the energy demand but can also produce surplus amounts
