Ah, this is another myth roaming the internet of high costs in renewable countries.
But the truth is the opposite.
What these figures fails to explain is Taxes. Denmark is a high tax country where everything is taxed high, like cars are EXTREMELY expensive to buy caused by taxes, compared to prices in the neighbour Germany.
AND taxes is used to drive the society, like free healthcare, free Universities, paied maternity leave, paied unemplyoment benefits etc. etc.
AND taxes vary from country to country, like low electricity tax in France and high in Germany and Denmark.
SO: If you made the same comparison of electricity costs PRE TAX, you would find that market cost of power is HIGHER in Nuclear France than in Germany and Denmark.
So Renewables has in effect lowered the market price.
Also to note is that Nuclear France has NO government fund to replace old Nuclear plants with new ones, while Germany has used electricity taxes to build a large fund for funding of future energy systems, being the dream of FUSION or improved Renewable technologies.
