Re: Wind and Solar vs Coal, Gasoline, Nuclear

Relevat for the thread: https://www.iea.org/newsroom/news/2019/april/key-electricity-trends-2018.html For the first time, natural gas overtook coal to become the leading source of electricity in the OECD in 2018, accounting for 27.4% of the mix compared to 25.4% for coal. Meanwhile, the combined con...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Everything else in the article was accurate as well except the statement about reliability which is generally good. This is all imortant to understand. Just replacing current electricity with rebuildables only gets us 1/5 of the way to getting off of fossil fuels. It is calculated that we can cut e...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

You can try to disguise cost increases by "correcting" them if it makes you feel better.. ...but you cannot "correct" for CPI, since energy cost is a major factor in the change of CPI. And if you seriously want to see the cost effect of RE introduction, you need to look at the data for the period o...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Its no use comparing energy to inflation, if you income does not increase at the same rate. Of course it does, inflation and income will correleate, and cannot over time change very much in a developed contry with stable economics. In many countries , Europe, Australia, UK, etc ,..electricity (and ...

In other news: Denmark just held a public bid for private renewable projects. It turned out to be 5 times cheaper than previous in terms of feedin-tarrifs. Technology was independent for bidding.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Getting back to the original subject - Nuclear, while it has its problems, is one of the carbon-free sources of energy that may help with reducing our carbon production. Unfortunately the very problems being caused by that carbon may make it more difficult to site and operate nuclear reactors. Many...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

What do you expect from the nuclear liars? ..... c-Si Wafer thickness is 180µm. So 1m² solar cells contain 180cm³of Silicium. The densitiy of Si is 2.34g/cm³, so this translates to 421g. Not counting gaps between cells and the module Frames, but also not counting losses (which usually are reused). ...

The oportunities for $0 cost will be far fewer than demands. 70% efficiency of pumped salt water hydro has already proven to be too low in a free market. 33% from intermittent electric over supply conversion to heat, and back to electric, is way too low to be cost effective.
