Although renewable facilities require upfront investments to build they can then operate at very low cost for most clean energy technologies the fuel is free.
Why do we need alternative sources of energy give two reasons.
First and perhaps most important we are in danger of ruining the planet s climate through carbon dioxide emissions.
Alternate sources of energy are necessary because.
If we continue to use fossil.
It is very important to do this for two reasons.
Traditional fossil fuel based energy sources release carbon dioxide in the air.

People take for granted what their actions do to the environment.
Soon all the existing reserves will be finished in about next 50 years.
Using alternative energy reduces the amount of digging drilling and mining we do thereby reducing stress on the planet.
Their use provides a reduction in greenhouse gas emissions.
We rely on the earth to provide the air water and food we need for life.
Harvesting fossil duels and then burning those fuels releases harmful chemicals into the earth s atmosphere and oceans.
This is one of the major reasons why it is so important to find alternative sources of energy.
Alternative energy represents the clean energy source that derives from a natural and renewable source of energy such as solar wind geothermal waves tides waste biomass hydrogen and so on.
