Energy and Climate paper - renewables, fossil, nuclear, hydro - the issues of dstribution

An interesting [long] read: https://www.mdpi.com/1996-1073/13/18/4839/htm


You might care to not read the opinion below (or the article). Sorry for the noise if so.


Opinion: I've always thought that #goinggreen was just an unacceptable 'cash cow' for vested interests to get rich on the back of poorly thought out political driven policies lacking in scientific rigour. If the 'planet is going to burn' without reducing fossil and moving to renewable, then anything 'we' do ought to be not for profit and for the world arguably.  PM Johnson's latest [and foolish?] bet on wind turbines (with all it's current and eventual revalations) and generally the pushing at all costs of  unfriendly battery EV and other tech (there must be better even if there are other challenges to over come) is just set to continue the ever increasing cost on the public purse for arguably little gain and more worryingly more 'damage' and for generations. It doesnt help when I recently read that there are surreptitious plans being considered to allow power gens. to turn off consumer power as and when they see fit  e.g. when it is likely many will be charging their EV cars  [rolls eyes in dismay].  They will do this by enforcing 3rd gen smart meters 'properly' connected up to allow this to happen.  If the current political nonsense and propoganda we have witnessed over the last 8 months or so relating to health, gets a hold in climate change (and how to address it and it probably already has) then perhaps the game is already up.


Rhetorically: Is nuclear the best bet for the planet at the moment (especially if ever they can crack clean[er] fusion). There are challenges to HFC based tech, but as it stands for EV and local power cell, it appeals more to me if the brilliant minds can sort it out. Is battery EV tech going to cripple us on many fronts. Can the UK grid cope. Wind turbines and solar come with so many ifs and buts they should not be relied on. Is this post in the wrong forum ! (apologies if it is - still the link above is related).


Best regards. Habs

    This paper is very balanced in it's approach to the subject. It is all very complex, and therefore difficult to explain, particularly to the layman. The economic aspects are treated very well, and illustrate the mega-problem with the idea of 100% renewables, even if this could be engineered. The economic cost of a move to renewables is very large indeed, and the one point which is not really discussed is whether it is necessary at all. It also points out that the energy density of biofuel production is very low, but does not point out that we cannot afford this area which could otherwise be used for food production, when the world is overall short of food. The USA production of bio-ethanol to add to petrol has caused a large increase in world food prices for some crops, particularly maize, a staple food in Africa. Many "Greens" would find this paper useful to temper some of the more exagerated claims which are often made by the media.
