Renewables rule

One has to wonder at the motivation for a relentless diatribe against renewable energy, such as expressed by Dr Wardrop in which he cites Australian politics as a means of furthering the argument (Letters, 29 August).

That particular political fra-

cas is more about politicians’ egos than energy policies.

The argument that renewables will never become the principal source of power in the long-term is lost and not worth debating. The question is not if, but when.

To be sure, renewables have problems, just as all other sources of energy do.

But on price, for these relatively new technologies, the trajectory of costs is rapidly downwards while other sources move relentlessly upwards.

The reduction in costs for solar and wind production over the last decade has been remarkable and their impact on the environment is a positive by-product. I am unsure as to how Dr Wardrop can contend that renewables cost us “… unsupportable environmental and financial damage…”.

Perhaps he could share his calculations with us? …particularly on environmental costs!
