Why do we need alternative sources of energy give two reasons.
We rely on the earth to provide the air water and food we need for life.
Renewable energy is providing affordable electricity across the country right now and can help stabilize energy prices in the future.
People take for granted what their actions do to the environment.
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.

The burning of fossil fuels is polluting the environment.
Their use provides a reduction in greenhouse gas emissions.
The mainstream fossil fuels like coal and petroleum are non renewable so their reserves are ending fast.
First and perhaps most important we are in danger of ruining the planet s climate through carbon dioxide emissions.
Using alternative energy reduces the amount of digging drilling and mining we do thereby reducing stress on the planet.
Soon all the existing reserves will be finished in about next 50 years.
Traditional fossil fuel based energy sources release carbon dioxide in the air.
