Solar Cell Inventor Wins Millennium Prize
adeelarshad82 writes "The inventor of a new type of solar cell won the Finnish state and industry-funded, €800,000 ($1.07 million), Millennium Technology Prize. According to the foundation, Michael Graetzel's dye-sensitized solar cells, known as Graetzel cells, could be a significant contributor to the future energy technologies due to their excellent price-performance ratio."

Oh FFS, I'm a Finn and I really don't have any problem with this. In the summary you'll find the price is "Finnish state and industry-funded". And the price is biannual, 400k€ annually is not really that much for the state, even if it were completely "my tax money".
You're over-simplifying things.
There is an optimum in every climate. Here's how it works:
You choose a certain period. Say, 30 years.
You check the price of the energy. You check the price of different kinds of insulation.
Insulation is a one-time investment, energy costs money all the time. You check which is the cheapest after 30 years.
In many houses an investment in insulation is worth the money and will pay itself back. But in some cases, the quality of the insulation is already such that it's just too expensive to add even more insulation to save those few euros/dollars/whatevers in energy.
