Spain: The Battle Over Water

Deutsche Welle (Aug. 21, 2013) — As a result of the economic crisis, many municipalities in Spain have sold their public water utilities to private companies. Now some local communities are finding out that the water supply networks are no longer being maintained properly and that water quality is on the decline. By the end of the year, about 60 percent of water utility management will be partly or entirely in private hands, making Spain the frontrunner in water privatization within Europe. Some experts are already calling it a "water bubble, and communities that are still trying to sell their water utilities are no longer able to obtain top prices. Now some communities are trying to regain public control over their water supply.

She focuses on energy systems and their effect on the climate.DW-TV: Welcome to the program. Scientists from the Max-Plack-Institute suggest that wind energy is limited. What's your take on that?Brigitte Knopf: First of all it's fully correct that there is in principal a physical limit on the wind potential. But it's not relevant for energy supply for the whole world. So it's not relevant for today or for 2050 or even 2100. So nothing to worry about at the moment?Not that much, no.Would you agree that solar power is the renewable that has the most potential at the moment?At the moment yes, it has a big technical potential. But you also have to consider the costs and you have to compare the different technologies and what is less expensive.Most worldwide energy needs at the moment are still being met by carbon fuels: oil, natural gas, coal.
