The biggest challenge of the energy transition is the integration of renewable technologies into a digitalized interconnected energy system, according to Ditlev Engel, CEO of DNV GL Energy, one of the largest energy consultancies in the world. “Technology is moving very fast”, Engel says in an interview with Energy Post. “Renewable energy growth has surpassed everyone’s expectations. Regulation and market design need to reflect this development.” … [Read more...]
The surprising story of the decline of electricity use in American households
Despite continued economic growth, American households use less electricity than they did five years ago, writes Lucas Davis of the Energy Institute at Haas School of Business. The reason may surprise you, notes Davis: it’s energy-efficient lighting. According to Davis it is not clear yet whether household electricity use has peaked or will rise again in future.

Costs of electricity generation compared: beware of simple metrics
With the rapid growth of renewables, comparing costs of different forms of power generation has become important for policymakers, investors and analysts. In these comparisons, the metric of LCOE (levelized cost of energy) is often used, but the U.S. Energy Information Administration (EIA) warns that this metric does not cover all the complexities involved. The EIA has written a short primer on comparing power generation costs. … [Read more...]
Divestment will not block German lignite
Stock divestment strategies have been widely proposed to undercut financial support for fossil fuels. The German lignite industry, however, cannot be tackled in this way, writes independent energy expert Jeffrey Michel in a highly informative analysis. Lignite stations and mines are owned by regional communities in the west and a Czech consortium in the east. Although some power plants are being phased out against government-arranged subsidies, … [Read more...]
How to calculate revenues of solar and wind power when the subsidies stop
As the recent offshore wind auction in Germany showed, unsubsidized renewables are rapidly becoming a reality. But how do you calculate the revenues from intermittent solar and wind power plants that receive no financial support, in particular in view of the frequent occurrence of zero or negative power prices? Carlos Perez Linkenheil, Marie-Louise Niggemeier and Simon Göß from Energy Brainpool, independent Berlin-based energy market experts, … [Read more...]
Interview Ray Thompson, Siemens: “Offshore wind increasingly fuel of choice”
As governments are focusing increasingly on industrial growth strategies, offshore wind is becoming a double win for policymakers, says Ray Thompson, Head of Business Development at Siemens Gamesa Renewable Energy. “Offshore wind helps them to achieve carbon targets and to create new jobs.” Thompson explains how the industry managed to bring costs down spectacularly and what is still in store: “Offshore wind is coming to represent a major … [Read more...]
With gas and hydro plans, Australian government is looking at whole picture
The Australian government has ambitious plans to expand hydropower capacity in Tasmania – and to restrict gas exports so they can be reserved for domestic use. Cle-Anne Gabriel, Lecturer in Sustainability at the University of Queensland, argues these policies are going in the right direction. Courtesy The Conversation. … [Read more...]
