Spain: The Battle Over Water

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.

Studio Guest: Dr. Brigitte Knopf, Climate Scientist

Deutsche Welle (Sep. 11, 2011) — Dr. Brigitte Knopf works for the Potsdam Institute for Climate Impact Research. 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. Renewables now only cover 13% of energy needs. Only a tiny fraction

Thailand Climate Protection Through Energy Efficiency

Thailand Climate Protection Through Energy Efficiency

Deutsche Welle (Mar. 13, 2012) — Thailand needs ever more energy for its industry. It already imports up to 10 percent of its electricity. The growth of industry is bringing a sharp rise in greenhouse gas emissions. Now a German-Thai project funded by the International Climate Protection Initiative is working for a more efficient use of energy, thereby contributing to climate protection.The Thai government has a long-term goal of "Low-Carbon Industry". It is collaborating with Germany in the umbrella organization "Energy Efficiency for Small and Medium Enterprises" on several pilot energy-efficiency projects in small and mid-sized companies. The Environment Ministry holds consultations regularly. The aim is to cooperate with German experts and develop an "Energy Use and Climate Protection Plan" for Thailand's economy.
