A couple interesting points below based on the article, which you can find here.
What it takes to pop solar on rooftops takes far more workers than the big industrial stuff that would replace coal fired power plants. The efficiency at scale is real.
Rooftop installations drove much of the growth this year. Household projects accounted for 63 percent of the industry’s jobs, with 15 percent of the workforce tackling commercial projects and 22 percent building utility-scale installations. That points to an interesting disjoint in the way the industry operates: the type of solar installation that replaces the most greenhouse gas emissions represents a smaller share of the solar workforce. The report says this is because utility-scale projects are less labor-intensive.
If this sort of growth continues, then Solar jobs will be the energy sector's most dominant type of work. That can seriously change the way Congress is lobbied. to be sure, Congressional representatives of places that still extract fossil fuels will be against it, but all that means is that companies need to look at the map and choose sunny places to hire people so that they can break those representatives constituencies and thus ensure long term growth with government support. Let's not forget-- government always picks winners and losers.
Going back to point #1 above-- there's a huge win-win-win for the president if he can see past the sterotypical GOP dislike of renewable energy. Power plants are usually government monopolies, which means that they receive corporate welfare. If he gave incentives to solar companies and the 50 states to ramp up on rooftop solar, it would begin the obviation of traditional power companies while ramping up the need for these workers. The third win is that opposition party Dems would have to work with him or look like they're not genuine about energy and the environment. Whether the opposition party works with him or not, he'd look like he was putting "America First" with regard to jobs and any dependence the US has to foreign energy sources.
You save a lot of oil if you don't have to transport coal by truck or diesel locomotive.
You also require less natural gas and oil pipelines if most electricity is coming from people's rooftops.
And a bonus? The idea of each homeowner generating and managing their own electricity usage falls inline with the individual responsibility and self-reliance ideals and principles of US conservative politics.
The environment, specifically, the carbon crisis, is probably the most important issue of our time. Let's use political and scientific realities to solve it.
