Global electricity grid must be upgraded urgently to hit climate goals, says IEA (www.theguardian.com)

Ministers have been urged to “open their eyes” to the need to build a vast network of new electricity grids to allow countries to hit climate goals, the chief of the world’s energy watchdog has said.

Fatih Birol, the executive director of the International Energy Agency (IEA), has warned that the equivalent of the entire global electricity grid – 80m km of grid – needs to be added or refurbished by 2040 to hit climate targets and ensure reliable power supplies.

Global investment in energy grids needs to double to more than $600bn (£492bn) a year by 2030 to hit national climate targets after “over a decade of stagnation at the global level”, the IEA said.

Unfortunately solar has left a bad taste in everyone’s mouth, because solar in general has very low margins and was often done by fly-by-night contractors. They cut corners, particularly with cable sizes, leading to them catching fire. These problems have been more or less resolved now, at least for solar farms on the ground in a field, however people are still wary of rooftop solar.

Huh, I installed solar more than 20 years ago and have been following the industry since then. This is the first I've heard that "everyone" has had a problem with it. That kind of negativity sounds like what electric companies would like us to believe. What's the source for this?

Ok, so maybe "everyone" is a slight exaggeration. However it is a known problem in the industry, in which I work. I've seen some crazy shit in solar farms, including the dodgiest HV switchgear I've ever encountered - and as an HV commissioning engineer I've seen quite a few.

You don't have to look far to find stories about solar farms catching on fire.

Yeah, the count of fires is up...

Shaw found that there were 56 recorded solar system fires in 2018, the most recent year of reported data, which is up 36% from the 41 recorded in 2017. In 2015, the first year that Shaw got data from USFA, there were 25. Since 2015 the Fire Administration has recorded 155 fires caused by solar installations, with 84 being residential systems and 71 being non-residential." https://www.pv-magazine.com/2020/04/23/solar-system-fires-are-on-the-rise-in-the-u-s/

...but so is the count of installations. There are probably more than 56 installations in my town, in my state there are 1,841,539 (https://www.seia.org/state-solar-policy/california-solar). The rising count is not a reason to dis the technology as a whole.

I wasn't dissing the technology, I was dissing the installers who cut corners, which typically is the root cause of the fires. Cheap equipment and undersized cables. If anything, fires should be going down as the industry matures - even in spite of the number of installations going up.

Also, I gave you a generic search link. I'm not in the US, but I knew the problem was the same all over.
