The world today uses more renewable
energy

than ever before since it contributes to the preservation of the environment and is economically sound;
however
Linking Words
, some argue that green
energy

could undermine the reliability of the global supply
as a result
Linking Words
of its dependency on climatic and meteorological phenomena.
This
Linking Words
essay will examine both views, but personally, I strongly advocate the adoption of renewable sources of
energy
Use synonyms
. On the one hand, opponents of renewables claim that the world could face disruptions to the power supply should they be fully adopted.
This
Linking Words
is largely
due to
Linking Words
the fact that many green
energy
Use synonyms
technologies
Use synonyms
currently in use depend on changeable and unpredictable phenomena
such
Linking Words
as wind, rain and cloud cover. To take the fastest growing sector as an example, solar panels can only be used in the presence of strong and direct sunlight, and
although
Linking Words
the problem of directness has already been somewhat solved with moving panel arrays, a cloudy few days could still result in a blackout if we depended entirely on solar power; something
that is
Linking Words
unlikely to occur today given current oil stockpiles.
However
Linking Words
, fossil fuels are a larger threat to
energy
Use synonyms
security since they are certainly finite in quantity,
whereas
Linking Words
renewable
energy
Use synonyms
is effectively infinite; once the Earth’s oil is depleted, there will be no
energy
Use synonyms
security without green
energy
Use synonyms
technologies

.
Furthermore
Linking Words
, problems of unpredictability can be mitigated by improving battery
technologies
Use synonyms
(to create a larger buffer), building more renewable
energy
Use synonyms
generators (to increase supply during ideal conditions) and improving current
technologies
Use synonyms
(to increase efficiency),
such

as in the moving solar panel example. Proponents of renewables
therefore
Linking Words
claim that they are the most economically sound option.
To conclude
Linking Words
,
while
Linking Words
many may believe that green
energy

technologies

are a threat to
energy
Use synonyms
security, the fossil fuels they frequently promote are a greater threat, and renewables are in fact the only sound option, both economically and environmentally.
