We brace ourselves for another visit to green fantasy land (‘according to the study’) where progress to imaginary nirvana is just around the corner, regardless of glaringly obvious realities pointing the other way.

Transitioning our energy supply from coal, oil and gas to wind and solar power is feasible, claims TechXplore. [Talkshop comment – empty assertion].
However, renewables require more land than conventional forms of energy generation.
The most affordable option for a fully renewable electricity supply in Europe is based on solar parks and onshore windfarms.
However, this solution requires some 97,000 km2 land, or roughly 2% of the total area of the European Union—an area equivalent to the size of Portugal.
Offshore wind and solar energy can reduce land requirements
Wind and solar farms change landscapes and their development is frequently the subject of controversy. This is especially true in the case of onshore windfarms, currently the most important technology behind the European energy transition, as these occupy large areas and are visible from a long distance.
Prioritizing the adoption of other electricity generation infrastructures in the future could reduce the space requirements of a fully renewable electricity system.
According to the study, three options could be pursued individually or in combination to achieve this goal: Offshore wind power, large solar parks, and roof-top solar systems.
Each of these technologies could limit land use to about 48,000 square kilometers—one percent of the area of Europe—or even less.
