Renewables, not thermal power, should get capacity payments - and be responsible for balancing. These are some of the explosive messages from a new report from the influential German think tank Agora Energiewende, which represents government, industry and NGO's. In an exclusive interview with … [Read more...]

As our electric utility system is moving from dumb and centralized to smart and decentralized, it is becoming increasingly vulnerable to cyber attacks. Are utility executives paying sufficient attention to these serious new risks? Energy expert Allan Hoffman, a former senior official at the U.S. Department of Energy, says the SONY hacking case should serve as a wake-up call to the energy industry. … [Read more...]
