Report Boasts 3 to 6x More Jobs from Green Investments

So I am looking at this report on green jobs

According to the report, renewable energy technologies provide three to six times as many jobs as equivalent investments in fossil fuels when manufacturing, installation, operation and maintenance jobs are taken into account.

This is marketing genius.  What this is telling me is that renewable energy technologies are 3 to 6 times more labor intensive - which from a macro perspective is not a great thing.  Where does that come from, are these renewable technologies three times harder to manufacture?  Three times more complex to install? Require three times the significant human input for operation or break down a lot?  Wait don’t answer that - I am not certain I want to know.

I would love to see more details on this topic.  If indeed these results are true we are either a.) spending too much emphasis on technologies which are flawed (but we can’t see that through the fog of government policy intervention that drives consumer choice), or b.) there is a lot of room for improvement in this industry in efficiencies regarding labor.

I suspect it is both - which creates two investment considerations.  The first what is the risks associated with companies that are in group ”a” - e.g., what happens to solar when tax subsidies cross break points, or wind tax breaks aren’t renewed (this was actually covered in a post here).  The second is where are the opportunities for the most improvement in group ”b” - what technologies have the chance to improve their labor profile the most - thereby generating profit for investors?
