energy can be converted from one type of energy to another. An example of this would be electrical energy turning into mechanical energy every time you use your blender. The electrical energy flows through the mechanical device providing it the power it needs to make the blade move in a circular motion and blend the items in the container. Another example of converting energy is when we use chemical energy in the form of propane‚ which turns into radiant energy when ignited‚ to cook food or provide

Planning Commission‚ (n.d.). Energy conservation also deals with generation of energy. This means electricity. Then‚ there are fuels such as natural gas‚ coal‚ or nuclear power. These fuels are used to generate electricity. Coal and natural gas are not renewable resources. Our country needs to start looking into wind‚ solar and bio mass resources before the nonrenewable resources are gone.

Energy that is obtained from solar radiation‚ water‚ wind‚ and geothermal energy is from nature. All those forms of energy are considered as renewable means because we can use them over and over again without harming the ozone layer and without causing pollution. For example solar energy‚ which is from the

Your suggestion and article provided about using wind and solar power would be a great solution to some of the energy crisis. I believe that wind and solar power will only continue to grow in popularity as time goes on. James Tera‚ I would agree with you and disagree with you to a point.

Solar power or solar energy is a technology that converts the power of the sun into usable energy. It is a resource that cannot be used up by us using it. Much of the world ’s required energy can be supplied directly by solar power. There are several types of solar

energy and power sources. Green energy is a term used for sources of power and energy that are environmentally friendly. Basically this includes anything that is renewable energy. Renewable energy is considered energy that is constantly being replaced such as wood‚ vegetable matter‚ and trash. Green energy ’s main focus is to use sources that can cut down on pollution. Some of these sources of power and energy are Biomass energy‚ geothermal energy‚ hydropower‚ nuclear energy‚ solar energy‚ wind energy

Fortunately‚ there are also renewable energy resources‚ such as water‚ wind‚ solar‚ geothermal‚ biomass power - and they will not run out as long as the Earth exists. For instance‚ the amount of sun energy hitting the Earth in one minute is greater than energy consumption of the entire planet during one year! These sources of energy are not

According to the Oxford Dictionary‚ alternative energy is energy generated in ways that do not deplete natural resources or harm the environment‚ especially by avoiding the use of fossil fuels and nuclear power (Alternative‚ 2012). 1.
