Renewable energy resources offer cleaner alternatives to fossil fuels.
What is not an alternative energy source.
There are many reasons the world is looking for alternative energy sources in an effort to reduce pollutants and greenhouse gases.
The energy transition to meet the world s needs for electricity heating cooling and power for transport in a sustainable way is widely considered to be one of the greatest.
Uranium is a radioactive element found in low amounts within all rocks on earth.
This includes sunlight geothermal heat wind tides water and various forms of biomass.
Not only is it a clean source of energy which means it doesn t create pollution and the myriad issues that arise from it but it is also a renewable energy source.
It is a non renewable resource because of its cosmic origin.
Alternative energy is a term used for an energy source that is an alternative to using fossil.
They are not completely problem free but they produce much less pollution and fewer greenhouse gases and by definition will not run out.
Several forms have become price competitive with energy derived from fossil fuels.
Better yet it also offers a number of secondary benefits that are not immediately apparent.
But breeder reactors could extend that source.
Sustainable energy sometimes called green energy is energy produced and used in such a way that it meets the needs of the present without compromising the ability of future generations to meet their own needs.
Power plant construction also uses a lot of cement.
While some people claim that nuclear power on its own perfectly fits the definition of a renewable source of energy it is uranium the commonly used nuclear fuel which does not fit into the scheme.
Nuclear is also not considered a viable alternative energy source because its waste is radioactive.

What is alternative energy.
The alternative sources of energy available today are harvested worldwide using clean technology that must be improved to increase its efficiency.
This energy cannot be exhausted and is constantly renewed.
Renewable energy is energy that is generated from natural processes that are continuously replenished.
Nuclear power is not considered a renewable source because there is only enough uranium to last 1 000 years.
Alternative or renewable energy sources show significant promise in helping to reduce the number of toxins that are by products of energy use and help preserve many of the natural resources that we currently use as sources of energy.
