Cost- all this green crap is economically cost prohibitive. It will hurt jobs and the economy.
Power density- most green power sources require a vast footprint in area to achieve the same output a coal or nuclear plant can achieve in 1/2000 the area or less.
Reliability- it tends to produce it least when you need it most, in the winter and at night.
Economy of scale- as you increase output you have diminishing returns because green power is highly location specific and the best areas are used first, also you begin transporting it over further distances.
Once you attempt at providing most your power from these sources (solar/wind) you’ll eventually reach a point where energy storage becomes required. At that point, it’s not so green anymore, and any of the competitiveness in cost is lost by a huge margin against any fossil fuel and nuclear.
Green power- a great political photo op. https://www.ft.com/__origami/service/image/v2/images/raw/https%3A%2F%2Fd1e00ek4ebabms.cloudfront.net%2Fproduction%2F8622237e-f176-4ce0-a124-9dfdb550b168.jpg?dpr=2&fit=scale-down&quality=medium&source=next&width=490
Not so good in reality.
Good sumation.
Germans can’t even count on firewood anymore, as there is a huge fine for going into the forest and harvesting trees.
