Losses drop or losses rises to 50?
If it go from 10 degree to 40 degree the losses must rise, and the energy production drops.

As the sun is not pointed at the panels your losses drop to 50% by the time you are off by 40 degrees or so if I remember correctly.
There is a mathematical equation to figure it out, I used to know it.

Yeah it costs half as much per wat but solar only produces power 1/5 of the day.
Dollar for dollar production that solar costs at least double the price of coal.
Fossil fuels and nuclear cost more and more over time. Renewables get cheaper over time, since they do not consume fuel.

Doesn't need fuel also doesn't produce power for most of the day.

How much energy could be generated if was possible to collect all the farts form USA people ?

Another energy source it's wasted everyday in every home, in the toiled. Yes, poop could became fuel for cars



Brazil had a university project to a biodisel from suage, or something like that. USA had one from wasted fat from restaurants, to became fuel for jets.

Poop should never go into the rivers. It should be collected to became fuel and/or fertilizer.

And even tires and plastic could became fuel :





But thermaldepolymerization process have some cost to anoy.
Pressure and heat, like nature creates oil, but in a speed-up fashion.

Best thing to do with poop is bio gas it and burn said gas in a boiler.
Then collect the waste solids as fertilizer.
Aside from a little government mandated ferric chloride it doesn't require any petro chemicals.

The power of poop. At least we're off of fusion power, at least for a moment. Dense thermal depolymerization is broadly applicable, old car tires for instance.*

A floating tidal stream turbine off the coast of Orkney has produced more green energy in a year than Scotland’s entire wave and tidal sector produced in the 12 years before it came online.

In 12 months of full-time operation, the SR2000 turbine supplied the equivalent annual power demand of about 830 households.

Its developer claimed the machine – the most powerful of its kind in the world – had set a benchmark for its industry due to its performance.
....
It produced 3GWh of renewable electricity during its first year of testing at the European Marine Energy Centre.

I stayed at a house in New Hampshire last month with a 10'x10' panel that tracks the sun and folds up at night. They have two houses, and the panel makes enough for both and earns them $200/year from the power company.

I am a fan of using bio-digesters instead of waste treatment as well. Couple the energy from that to cover with wind and pv solar as well should cover most energy needs. You would most likely still need some conventional generation to be running all of the time.

The cost of batteries is coming down significantly, before too much longer they will be cost effective to have for grid level storage to even out the generation from renewables.

Sure, build grid level batteries, then there won't be any batteries to build electric car batteries.
