1.Advantages of Alternative Energy Sources
Alternative energy represents a renewable energy source that never runs out
Fossil fuels are considered non-renewable energy sources because they are finite sources of energy due to the fact that they will run out in just a few decades.
Alternative energy is considered a renewable energy source because provides a sustainable and stable supply of clean energy in the long term.

Disadvantages of Alternative Energy Sources

The today’s technology used to generate renewable energy (clean electricity) has its limits.

Wind turbines harness the power of the wind.

The low efficiency specific to these technologies creates a problem with the feasibility of such projects because the investment may return in a long period of time, which in some cases does not justify the initial investment.
