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

It is considered that renewable

.

Firstly

, I agree that the initial

expenditure

on renewable

is high and sometimes unaffordable.

For example

, the manufacturing and installation processes of

devices like solar electricity panels are relatively expensive.

For instance

requires a lot of space for installation, but I disagree that these drawbacks can’t be solved in the future in order to make the world a better place to live. I disagree that the issue of the high cost of running

In addition

Therefore
