It's bit of a loaded question. What's the time frame for measurement? We've had wind farms operating for close to 30 years in some areas. Are we looking at the 6 months of heavy diesel equipment used in building the farm or the impact spread out over three decades?You seem pretty educated on the topic so I was wondering, is the rhetoric regarding the creation of the renewable farms producing more CO2 than the plants remove true or not?
A more nuanced answer is
- over the life of a wind farm there will be less CO2 produced compared to fossil fuels
- the technologies are improving rapidly where the original 0.2MW turbines are relatively 'dirty' compared to newer 17MW turbine
- same with solar panels. Efficiency (conversion to electricity) used to be less than 10%. Current panels are 21%, and newly developed panels hit 47%
- once a solar farm is built, the process of swapping out panels for more efficient models is quick and easy
- wind turbines and solar panels are getting bigger, cheaper, and more efficient. Even without the climate argument, it's simply getting to the point where the economics tilt in favour of renewables.
Anyone making an argument that renewables create more CO2 than fossil fuels usually has to cherry pick some very specific details and ignore the more nuanced answer in order to make it a culture war issue. I'm old enough to remember people saying mobile phones were a fad items and would never replace a landline because the batteries were big and heavy and needed to recharge every couple of hours. Same with computers. They'll never replace a typewriter because a typewriter doesn't need a power cord and will never 'crash'.
