OR . . . Will we create an "Internet of Things?"

If you're asking about the gop; the answer is "of course."
Everyone else;22nd century and beyond.

If solar panels cost $1 per Watt,
. . . why do you pay $5 per Watt to get a solar system?
Roughly, there are 2 categories of costs associated with building a residential solar system:
. . . 1) Hardware costs, such as the costs for the solar panels.
. . . 2) Non-hardware costs, also referred to as the “soft costs”.
Hardware costs relate to the materials needed for a solar system:
. . . solar modules, the inverter(s) and the installation materials (such as the racking system).
. . . According to a study of the Department of Energy (US), these hardware costs add up to $1.90 per Watt:
. . . . . . Module costs are $1.03/Watt,
. . . . . . Inverter costs $0.43/Watt, and
. . . . . . Installation materials $0.44/Watt.
“Soft” costs, to actually install the solar system on your roof, permitting fees and the costs to acquire a customer.
. . . All soft costs together add up to $3.32 per Watt.
. . . . . . Installation labor costs $0.55 per Watt,
. . . . . . customer acquisition $0.48 per Watt, and
. . . . . . supply chain $0.61 per Watt.

UBS note that the pace of closures in the coal and gas sector in Europe is accelerating,
. . . even as the growth in renewables steadies and, in some countries, slows.
According to their data, some 70GW of coal and gas-fired generation shut-downs,
. . . have occurred in the last 5 years, and the pace is increasing.
The combination of reduced demand, and yet more renewable energy additions over the next 2 years,
. . . will force the closure of at least 24GW of thermal capacity (coal and gas), and
. . . could lead to another 30GW of closures.
Nearly 1/2 of the remaining 260GW of coal- and gas-fired generation in Europe,
. . . is cash-flow negative, meaning they do not earn enough money to cover basic costs.

Wall Street Journal, advised all 50 states to boycott:
. . . . . . Global thinking,
. . . . . . National policy, and
. . . . . . EPA’s Clean Power Plan (Climate Change).
Environmental Protection Agency Acting Assistant Administrator Janet McCabe,
. . . EPA took care to incorporate input from the utility sector,
. . . by crafting a plan that provides utilities with “enough time,” and
. . . “a wide range of options” to reduce carbon pollution.
There has never been an instance in which,
. . . Clean Air Act standards have caused the lights to go out.
