Alternative energy sources that use the natural power of the wind, waves and sun are too expensive and complicated to replace the coal, oil and gas that we use to power our cities and transport. To what extent do you agree or disagree with this opinion?

Nowadays, it is clear how

global technological and economic growth can no longer occur at expense of our environment. Few would debate that, while industries and transport still rely on traditional

First

will lead to the total consumption of oil resources alongside contributing to the global pollution through fumes emissions.

Therefore

approach

to

policies will not only lead to a catastrophe from an environmental standpoint but will

also

inevitably lead to its own destruction once the global resources are completely consumed. In

this

setting, several scientists, funded by ethical societies and companies, are paving the way for the development of newer environmentally friendly

energy

forms

. There is no doubt that

this

approach

will be more expensive and laborious at the very beginning. In fact, renewable

energy

implants, like fields full of solar panels or wind turbines plants, require a lot of expenses both for their building and manutention.

Furthermore

, the efficiency of these stations is still far from the desirable levels, since more advanced systems are still under development, as it happens for every new technology. Despite these initial limitations that may be felt like a downfall by many leaders and cabinets, investing in renewable energies like wind and wave turbines, solar panels, or hydroelectric dams, represents the only way to guarantee a continuous supply of

energy

for the generations to come. Interestingly, some cities have already based their energetic requirements on renewable

forms

. Recently, in London 80% of the houses’ heating
