No, your numbers don't make sense. The percent difference between the items is identical and did not change.
Please do not make the error of comparing absolute difference in prices, because that is not how money is compared.
The biggest problem with energy taxes is that when you increase the cost of energy, you also increase the cost of building a solar power station. So you can never catch up.
If solar power was cheaper than hydrocarbons, then no tax is needed, people would use it on their own.
If on the other hand you add tax, then solar power stations become more expensive to build, so they have to charge more for the energy - so much more that tax does not help them.
