"Global communication is an important basis for quickly giving all nations access to climate protection technologies and strategies," said Hans-Josef Fell, founder of German think tank Energy Watch Group. The renewable energy supplies have been studied and proven to be technically feasible and economically advantageous, he added. Fell noted that isolation, on the other hand, leads to "a slowdown in climate protection activities," which leads to "catastrophic consequences due to the effects of global warming, such as the destruction of habitats and food bases."
