3. Introduction
Renewable energies have both advantages and disadvantages
even if some people think they do not have anything wrong.
Although there are many we are going to mentioned the
following ones:
● Biomass
● Marine energy
● Solar photovoltaic

4. Disadvantages
-Cost: Living things are expensive to care for
Biomass so it has to be considered when we have to
use the waste for fuels.
-Viability: Combustion of biomass products
require some land where they can easily be
burnt. As it produces gases as methane.
-Cost: The huge installations have an expensive costs.
Marine energy -Viability: Only power plants and towns near the ocean will benefit
directly from it so marine is not a viable source for everyone.
They depend on the weather.

5. -Cost: As they are fragile and can be damaged
Solar photovoltaic easily additional insurance easier are of
ultimate importance to safeguard the investment.
-Viability: Solar energy has intermittency issues so it makes
solar energy panels less reliable a solution.
PV panels’ installations they require relatively large areas for
deployment.
