Energy is the fuel that runs the engine of the world economy. Believe it or not our need for energy is not primarily to run economies but intrinsically to create order in the world. Wind energy Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing‚ grinding grain‚ and for irrigation. Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been

Alternative energy resources What are Alternative energy resources?? It is any energy source that is an alternative to fossil fuel. It is a form of energy derived from a natural source‚ such as the sun‚ wind‚ tides‚ or waves and are also known as “Renewable Energy” that do not use up natural resources or harm the environment. They are considered alternatives because they can be future replacements for the fossil fuels that now meet a considerable portion of our energy needs. What Energy Resources

the start of the civilization they always used energy in order to cover their needs and in order to develop their selves‚ in the past people made fire by cracking two pieces of flint causing sparks against dry tinder or fleece. But now there are many alternative sources of energy for people to use. And fossils fuels helped them a lot. People have used more than 90% of fuels‚ such as oil‚ coal and natural gas to produce electricity. These things are non-renewable

How can alternative sources of energy be harnessed effectively? With the development of economy and society‚ existing energy sources have been hard to meet the increasing market demands. due to the lack of fossil fuels and environmental problems‚ an increasing number of people pay more attention to alternative energies because they are directly related to the future economic and social development. Therefore‚ this essay will discuss how to harness alternative sources of energy effectively‚ with

technologies with alternatives that have comparable or better performance‚ but do not emit carbon dioxide. We call this Alternate energy. According to Oxford Dictionary‚ Alternative Energy is energy fueled in ways that do not use up natural resources or harm the environment. Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have

Alternative Energy Sources In our homes‚ at our workplaces‚ and in our leisure‚ humans consume energy in every activity at alarming and around the clock pace. We have past the days of wind-up clocks and toys‚ foot-pedaled big wheels‚ and hand-cranked cars. Today‚ everything we operate comes fully loaded with all the ‘bells and whistles’‚ neon lights‚ and fancy remote functions. But at what price is this costing us‚ our environment‚ and our future. Alternative energy sources‚ also known as renewable

How can alternative sources of energy be harnessed effectively? Finding Alternative energy sources is a significant issue from all over the world. In contemporary society‚ due to the lack of fossil fuels and environmental problems like air pollution‚ alternative sources of energy have being utilized widely for different domestic and industrial applications. Biogas is one of the alternative energy which instead of fossil fuels

Hydrogen Fuel As An Alternative Energy Source To Replace Fossil Fuels Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. Many nations count on coal‚ oil and natural gas to supply most of their energy needs‚ but reliance
