Nowadays most green energy is becoming ever more prevalent in both developed and developing countries. Some argue they greatly reduce costs and are better for the environment, others believe they are a serious threat to energy security. Discuss both views and give your opinion.

The world today uses more renewable

energy

than ever before since it contributes to the preservation of the environment and is economically sound;

however

, some argue that green

energy

could undermine the reliability of the global supply

as a result

of its dependency on climatic and meteorological phenomena.

This

essay will examine both views, but personally, I strongly advocate the adoption of renewable sources of

energy

. On the one hand, opponents of renewables claim that the world could face disruptions to the power supply should they be fully adopted.

This

is largely

due to

the fact that many green

energy

technologies

currently in use depend on changeable and unpredictable phenomena

such

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

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

unlikely to occur today given current oil stockpiles.

However

, fossil fuels are a larger threat to

energy

security since they are certainly finite in quantity,

whereas

renewable

energy

is effectively infinite; once the Earth’s oil is depleted, there will be no

energy

security without green

energy

technologies

.

Furthermore

, problems of unpredictability can be mitigated by improving battery

technologies

(to create a larger buffer), building more renewable

energy

generators (to increase supply during ideal conditions) and improving current

technologies

(to increase efficiency),

such

as in the moving solar panel example. Proponents of renewables

therefore

claim that they are the most economically sound option.

To conclude

,

while

many may believe that green

energy

technologies

are a threat to

energy

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