One step closer to abandoning time changes twice a year in the EU

The Guardian writes:

The European commission will recommend that EU member states abandon the practice of changing the clocks in spring and autumn, with many people in favour of staying on summer time throughout the year.

Apparently 80% of 4.6 million respondents in an official consultation favored staying on summer time all year round.

I would like to see some studies (other than the experiment in Russia a few years ago) about permanent summer vs. winter time.
