(Xinhua) -- Visiting Finnish Prime Minister Matti Vanhanen said here Tuesday that the European Union (EU) needs to diversify its sources to obtain sufficient energy. Although Russia is a reliable energy source, the EU needs to diversify its sources to obtain sufficient energy, such as natural gas from the Near East and Africa, said Vanhanen, who is on a one-day official visit to Hungary. Even so, there will be insufficient energy for the EU, Vanhanen said, stressing that more investments need to be launched in the fields of hydraulic energy, geothermal energy and tidal energy.
Vanhanen said concentration should be put on developing second-generation biofuels which will have good prospects in the EU despite mounting doubts.
