Renewable Energy in Malaysia Energy is a key driver for economic growth‚ constituting about 20% of the Gross Domestic Product (GDP). In 2010‚ the total primary energy supply was 3127.7 petajoules. The main energy sources of commercial energy supply were crude oil‚ which accounted 44.7% and natural gas which accounted 41.6%. These sources remain major ones. However‚ the share of coal and coke increased from 9.1% in 2005 to 11.2 % in these years and only 2.5% came from the non-fossil source of hydro

and work. On a global scale renewable energy supplies a significant benefit to our planet such as‚ lowering energy costs‚ job creation‚ and preserving the environment. With energy costs continuously on the rise and more frequent disasters affecting us as a whole‚ the fact remains that moving toward renewable energy forms most certainly makes these problems vanish. Though not an easy task it is safe to say that the world is headed in a green direction. Energy costs have risen in the Unites States

RENEWABLE ENERGY RESOURCES ABSTRACT The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e.‚ coal‚ petroleum and natural gas) and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the

The energy that is used today comes from fossil fuels‚ which is a nonrenewable limited resource that will eventually be used up. Alternative energy sources such as solar‚ hydroelectric‚ geothermal and wind energies can be used‚ to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide electricity for homes and businesses. Hydroelectric energy can

Potential Energy: Potential energy is the stored energy of position possessed by an object. Potential Energy Formula : Potential Energy: PE = m x g x h Mass: Acceleration of Gravity: Height: where‚ PE = Potential Energy‚ m = Mass of object‚ g = Acceleration of Gravity‚ h = Height of object‚ Examples: 1. A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg‚ h = 20

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
