Please understand that my house is a single-family unit, on roughly 1/3 acre, in Southern California's Mojave Desert.  That means that I have a lot more ground surface, as well as roof surface area, available for use in collecting solar energy than do MOST PEOPLE in the USA.  In our cities, there's a lot less available roof or land area per person that can be devoted to energy production than my neighbors and I have.

So, to answer your question:  During summer months my electric bill drops to zero, although I still have to pay for the connection to the power grid.  Our utility company no longer pays us for the power we put back into the grid; but the meter runs backwards.  At night, since I don't have a battery bank to store electrical energy from the day, I draw electrical power from the grid, and the meter runs forward.  At the end of the month, if I've used more power from the grid than I've put in, I have a small electric bill to pay.

During winter, with the fewer hours of usable sunlight, I have an electric bill.

Generally, my electric costs are lower - - - but of course I have to pay for the solar cell arrays as well as for my windmill, plus the maintenance, repair, and replacement costs.  It probably comes out about even for me.  Which means for a city dweller in an apartment building, they'd get absolutely no benefit at all.

We need to develop fusion power plants!

Thanks for that.  We can't afford the initial expense of getting solar panels installed, so you were the best person to ask.

Preach!

So, you've shut down your coal mines?

Nope.

But we are finally moving in the right direction.

It is good to see.

How so?

The article you were replying to, but obviously did not read.

What is obvious is that you did not find that article(?) very interesting since you had nothing to offer 'from' it!

So, 3d printed concrete tiles will replace your coal power and export industry? How so?
