30 Million Solar Homes Would Create 1.77 Million Jobs and $69 Billion In Energy Savings, Report Finds (cleantechnica.com) 318

A new report (PDF) from the Institute for Local Self-Reliance (ILSR) finds that installing rooftop solar panels and community solar systems to serve the equivalent of 30 million American homes would create 1.77 millions jobs and $69 billion electricity bill savings over the next five years. CleanTechnica reports: In addition to creating 1.77 million new solar jobs and reducing energy bills by $69 billion, the report found that enacting the 30 Million Solar Homes policies would over five years: Eliminate global warming air pollution equivalent to closing 48 coal-burning power plants or taking 42 million cars off the road for a year; Increase new solar capacity nationally by 151 GW; and Power the equivalent of 20 million households in marginalized communities with local solar.

In the report, these economic and environmental benefits are broken down by state and congressional district. An interactive map further illustrates the local impacts of the 30 Million Solar Homes proposal and gives viewers an opportunity to share the report with their elected officials.

      TFA doesn't say solar panels save money. It says they save on "energy costs" but ignores the cost of the panels since they aren't "energy".

      Basically, the $69B is the amount you would save if the panels were free and automatically installed themselves.

      We could require the installers to be blindfolded and to wear boxing gloves. That would double the labor required and thus "create jobs".

Which is it? Save the world or line the pockets? Because the amount of money is a zero sum game and if we are serious about rapid adoption the last thing that we need is artificial price inflation to slow sales.

      What am I missing here, Is solar really that expensive that you need 1 full time person for every 15-20 homes installed? that sounds incredibly bad efficiency.

      Depends on how you count and how you look at all the related labor. A solar install has a sales office and associated staff. Once a system is sold, there is a mechanical / electrical engineering effort (design documents, roof load calculations, electrical load calculations, electrical design), acquisition of permits, logistics in scheduling the materials and crew to the install job, the actual install job, inspections. The solar panels, roof racking, inverters, meters, and other electrical components need to be made by someone, shipped, delivered, and inventory tracked. A (proper, permitted) solar install is more than a guy slapping a couple of panels on the roof and plugging them in. When you add up all people involved in getting 15-20 solar installs done end to end, I can see it being a year's worth of aggregate labor. Think of it this way - a full time person puts in about 2000 hours a year. For 20 solar installs it would be about 100 hours effort / labor across the entire supply chain per install. That doesn't seem outlandish to me.

    ... installing rooftop solar panels and "s to serve the equivalent of 30 million American homes would create 1.77 millions jobs and $69 billion electricity bill savings over the next five years.

    69 billion over 30 million homes comes out to $2,300 per home - over five years, or $460 / year savings.

    Somehow I expect that the solar upgrades would eat a LOT more than $2,300 per home. Just for starters, those 1.77 million workers (assuming they're full time jobs) will want more than $3.90 per hour.

    Or is that "savings" number what's left of the money that would have paid the old electric bill after the solar equipment manufacturers, contractors, and laborers are paid off instead? That might make a LITTLE more sense. My electric bill runs near $220 a month (at silicon valley's socialized electric rates, without air conditioning). So $460 is a little over two months of it. Ten for them and two for me over five years. Alternatively, they get the full old bill for 4 years and two months and then I start to get "free" power.

    That is starting to get into the vaguely plausible range, but still far off from sanity. If it all went to labor the1.77 million workers would be paid about $19/hour. That bill was for 29.3 kWhr/day, or 5.86 kW of panels assuming 5 solar hours per day. If it all went to solar panels they'd run 37.2 cents per watt. Since panels were 30 cents per watt the last time I looked, there's a lot more to an installation than bulk panels, and the contractors and laborers will want to be paid. So the numbers still don't seem to make sense.

    And what's a "community solar system", commissar?

    • The cost to do it is predicted to be $137Billion. [ilsr.org]

      If the 30 Million Solar Homes package is implemented as a whole, the federal government would invest a total of $137 billion over the next five years to help deploy local rooftop and community solar systems across the country.

  • I am reminded of a trial balloon for increased ethanol production from the (first?) Bush administration.

    The additional corn production for the plan would have required something like 175% of the arable land in the US. I forget the figure, but it was more than all of the farmland . . .)

    So what multiple of available solar production will this take?

    And if it were attempted, what would this multiplication of demand do to prices?

    And how many would be in homes where it would actually make sense? I looked at it when I had to redo my roof, but with an annual electric bill of $1,300, it makes no sense if I can't go off-grid for $10k.

    During summer days, we're already overgenerating during the day, and then on flex alert to avoid blackouts from 4pm-10pm.

    Adding more solar won't help. In fact, it'll make the problem worse by making other forms of power less economical. Doesn't matter if the wind blows between 9am-4pm if we already have plenty of power from solar panels.

    The difference in net metering will also make household solar itself uneconomical. We already earn $0.24/kWh for the solar we overproduce during the day, and pay $0.40/kWh in the evening. With more overgeneration, that'll shift. I expect in a few years power will be $0.05/kWh during the day and $0.50/kWh in the evening / at night (when we'd really like to charge our EVs). Payback time for solar panels will rapidly exceed their lifetimes.

    What we need is *storage*. And a lot of it. We don't have enough lithium to make EVs *and* powerwalls for everyone anytime soon. But pumped hydro (and in fact, any hydro) doesn't count towards meeting our legislated green power goals.

More power from gas and renewables will meet near term goals without actually building storage.

    It's always easy to tell people how many jobs will be created by spending some money, and doubly so if your planned activity has no incentives for efficiency. It's also always easy to get people to cheer for "free stuff", as long as THEY are not the ones paying for it (if "free" was actually possiblr, that is).

    One problem is that the money has to come from somewhere, and that ALWAYS turns out to be average ordinary working people - NEVER the ultra-rich who have a double-pronged protection, first by having lawyers and accountants, and second by contributing cash, free corporate jet flights, and other benefits to politicians. These solar panels will not be paid for by mermaids, leprechauns, or unicorns - the money will be taken (directly by higher taxes, or indirectly by taxes on businesses which pass those through to their customers as higher prices) from average people, many of whom cannot afford solar panels for their homes.

    The second problem is that there's no such thing as "free" [in the beer sense, not the speech sense, though the latter seems on the decline these days]. If something requires matter or energy, then it cannot be "free" - it will take effort to obtain and transport it, it and that effort has a cost. If something requires human labor, it cannot be free - even if you are into slavery and think you can force somebody to work for no wages, you'll still have to provide stuff they need to stay alive and perform the work. Whenever somebody offers something for "free", what they are really saying is that the person getting the item will not have to pay for it, because somebody else is (willingly or unwillingly) picking up the tab.

    The sort of people who write reports and papers like this one rarely stupid and lacking in comprehension of the details of what they are advocating for, to the contrary, they are usually well-educated and clever propagandists who are intentionally providing only one side of the ledger, which is not an honest accounting practice.
