Fossil fuel is the main source of energy. In some countries, the use of alternative sources of energy is encouraged. To what extend do you think is a positive or negative development.

Nowadays, fuels

such

as oil, gasoline and natural gases are still the most used source of

energy

consumed around the world.

However

, some

countries

have started to shift their energic consumption towards greener solutions

such

as solar, wind and hydric powers, showing that it is possible to have renewable and sustainable forms of power.

This

essay supports

this

idea, presenting the positive aspects related to renewable

energies

compared to fossil fuels.

Although

the recent positions taken by many

countries

on the consume of no-renewable

energies

, still they are widely used, especially in developing

countries

. Along the decades, the extraction of petrol and natural gases, have contributed in creating an enormous amount of wastes, like plastic and oil residues, increasing dramatically the levels of pollutions; compromising the livelihood both many species. In places like the Niger Delta, the oil extraction contributed to the devastation of an entire ecosystem, polluting both people and animals.

Also

, another aspect is that fossil

energies

are limited in time and

therefore

need to be replaced with other forms of power to sustain the world

energy

demand. On

this

sense, many

countries

such

as Netherland, Canada, Norway or Japan have started to shift their

energy

production toward renewable

energies

, creating centres and factories with

such

purpose. Solar panels and wind turbines are forms of renewable solutions applied in these

countries

. They are expected to

last

longer than fossil fuels and, in terms of

energy

, are efficient as much as fossil fuel, with the huge difference they are not either polluting or creating wastes. In conclusion, adopting greener solutions

such

as renewable

energies

rather than fossil fuel, are the real key to reduce both pollutants and greenhouses emission.

Also

, they represent a sustainable way of getting

energy

which is expected to

last

much longer than petrol.
