As population grows alongside as rise of the industrialization and development, globe demand for energy becomes even more complex, but the planet has limited energy sources. Without continual input of energy, life on earth surely will no longer exist. It affects education, health, political power and socioeconomic status. Human spends a lot of energy, especially from fossil fuels, such as coal, oil, and natural gas to generate electricity on various activities. Another alternative energy comes from renewable sources such as wind, water, geothermal and bio-fuel.
Where does energy come from. Energy is all around us; it is a physical quantity on our earth's physical systems. Its flows including atmosphere, hydrosphere, lithosphere and biosphere. It moves in and out of this systems. Our planet's energy comes from the internal sources such as geothermal from radioactive and rotational from the spinning of the earth, while the sun is the major external source to run certain systems. In order to have adequate supply, we have to be able to improve our energy efficiency by using natural resources more responsibly to enhance the quality of life for everyone.
