Inaccurate statement.

https://qz.com/2113243/forty-percent-of-all-shipping-cargo-consists-of-fossil-fuels

40% of traffic is for petrochemicals, which according to this article is coal, oil, gas, and things derived from them, which would include fertilizer and plastics and probably some other stuff too like industrial lubricants, asphalt etc. Not just fossil fuels, so not all that 40% would be affected by a switch to renewable energy. It's also worth noting that building out renewable energy generation involves shipping a lot of hardware around the globe as well.

Also it requires shipping oil to fuel the mining operations needed to produce full scale renewable energy. But if we wait a little bit the quality of power output from the same mining inputs will improve which means renewable later requires less total mining than full scale renewable now, and so you will use less fuel to do that smaller amount of mining.

What people don't realize is that the expense of renewable technology mostly is fuel. Fuel to mine it, fuel to move the raw materials, fuel to refine it, fuel to manufacture it, fuel to ship it to you. The total labor is quite small. So if taken on a specific case the financial perspective alone of a particular application of renewable vs conventional energy the numbers don't add up then likely the renewable is less green. If you wait a little bit for the green cost to come down that indicates improved efficiencies and now it actually is green.

So the answer to make the world more green is not to shift our calculations to spend money on green solutions beyond financial sense. It's to work on technology to lower green costs until it naturally makes sense and thereby also make it more green at the same time.

Renewables are more climate efficient and cheaper. Today. All this included. A wind turbine, depending on size, position etc, generates the amount of power used in it's construction within 2.5 - 11 months. Over it's life cycle it generates about 40x the energy you put in. There is no valid excuse to keep burning stuff because it appears cheaper short-term.

Yeah, I feel like GP was a comment that was valid 10-20 years ago, but not now. We improved green energy during that time by a lot. It's past time to deploy it as fast as we can.
