Can EU become totally renewable by 2050?

Some respected European politicians and energy experts have recently stated that EU could by 2050 completely satisfy its total energy demand from renewable energy sources. In order to do so, all EU countries would have to work together and make huge investments in further development of renewable energy technologies, especially renewable energy storage technologies. Is such scenario really possible?

To some this may (rightly) seem like some sort of "green utopia" while there are some that are really convinced how this is very much possible, on both economic as well as technological level. This optimism is mostly based on some recent estimates, according to which Europe, together with North Africa has excellent renewable energy potential to produce approximately 140,000 terawatt hours of energy, which is around 20 times the amount of current energy consumption in Europe.

Current EU's renewable energy goal is 20 % of energy coming from renewable energy sources by 2020, which many energy experts believe will be achieved with relative ease, especially since the recent data shows that 60% of all investments in energy sector were transferred towards renewable energy projects.

What some energy experts keep forgetting is the fact that EU is still not united body when it comes to energy policy. You have countries like Germany and Spain that are making huge investments in renewable energy sector, France meanwhile continues to further invest in new nuclear power plants, while central European countries still invest in thermal power plants based on fossil fuels and look reluctant to drastically reduce CO2 emissions.

The other important part in this story is the fact that many countries are still not ready to give Brussels all the power in making joint energy decisions because this could put in jeopardy some bilateral energy agreements that these countries have with countries like U.S. and China, which enable these countries to get certain energy resources under privileged conditions.

Some energy experts even dream about Pan-European renewable energy network that would reach entire EU by connecting Spain's solar and wind power projects with geothermal power plants in Italy, offshore wind farms in Britain and Denmark, and hydropower projects in Scandinavia.

Renewable energy projects of this magnitude look highly unlikely in EU because differences among countries still look like a too big obstacle in making such important decisions. Thus totally renewable EU by 2050 is just a nice dream that has more to do with the science fiction than actually being possible in real life.
