Renewable energy generation is still on the rise in Germany, though at a much lower pace than in the years around 2010, writes Marius Buchmann of Jacobs University in a detailed overview of the German electricity market in 2017. Costs of the feed-in tariff are stagnating, notes Buchmann, but redispatch costs which grid operators incur to keep the system stable, reached a new record far above âŹ1 billion.

The rush for cobalt and what it means for EVs
There are no short-term alternatives to using cobalt in electric vehicle batteries today, writes financial energy specialist Gerard Reid. Even if the cobalt price continues to go up, it will be a long while before production is able to match growing demand, Reid argues. … [Read more...]
In the new era of inexpensive renewables, policy should remove systemic obstacles
As the cost of renewables goes down, the old approach of subsidizing generation no longer makes sense, writes Johannes Urpelainen of The Center on Global Energy Policy. We need a revolution in energy policy. Article courtesy The Center on Global Energy Policy. … [Read more...]
How Shellâs new Sky scenario achieves net zero emissions
In Shell's recently published Sky climate scenario, the energy system reaches net zero emissions by 2070 using several technologies that are at an early stage. David Hone, Chief Climate Change Advisor at Shell, explains how this would work and why Shell regards this scenario as plausible. Courtesy David Honeâs Shell Climate Change blog … [Read more...]
How aggregators will alter fundamentals of electricity business
As the number of âprosumersâ with batteries grows, huge opportunities will be opened up for aggregators who will be able to optimize these behind-the-meter-assets, writes energy expert Fereidoon Sioshansi, publisher of newsletter EEnergy Informer. Sioshansi explains how this development is likely to transform the electricity sector. … [Read more...]

How energy storage is starting to rewire the electricity industry
A world of low-cost batteries will transform the way the electricity and automotive industries operate and how homeowners, businesses and utilities produce and use power, write Eric Hittinger and Eric Williams of the University of Rochester. What is more, their research shows that storage is "future-proof" - it works no matter how the energy system evolves. Article courtesy The Conversation. … [Read more...]
Shellâs new SKY scenario shows how to meet the goals of the Paris agreement
Shell has launched a new scenario that illustrates a "technically possible but challenging pathway" for society to meet the goals of the Paris Agreement on climate change. The Sky outlook sees a rapid energy transition taking place over 50 years reaching net-zero emissions in the energy system by 2070. Courtesy David Honeâs Shell Climate Change blog. … [Read more...]
Energy storage does not always make the electric grid cleaner
Energy storage can help grids use more wind and solar power, but it does not always reduce carbon emissions, write Naga Srujana Goteti, Eric Hittinger and Eric Williams of the University of Rochester. In some cases, adding storage actually even increases carbon emissions. This happens when consumption is shifted to periods when coal power is used more. Article courtesy The Conversation. … [Read more...]
Why the future of batteries is lithium and why their impact will be bigger than you think
The tremendous advances being made in lithium battery technology are being underestimated by many people, writes financial energy specialist Gerard Reid. Competitive EVs are just a few years away. They will be followed by radical improvements that will have huge implications for air and ship transport as well. Courtesy Energy and Carbon blog. … [Read more...]

Exclusive interview: Bertrand Piccard will go around the world again â with 1,000 solutions
Bertrand Piccard, the man who flew around the world in a solar-powered airplane, will be taking another trip around the world. This time he will show governments 1,000 innovations that together will make it possible to reduce energy consumption and greenhouse gas emissions by half. âI want to show that it is possible and profitable for countries to be much more ambitious in their climate policiesâ, says Piccard, who considers this the second … [Read more...]
The spectacular success of the German Energiewende- and what needs to be done next
While a government is being formed in Berlin, which will have important implications for the future of the Energiewende, author and scholar Professor John Mathews of Macquarie University in Australia, looks back on what Germany has achieved so far with its unique energy policy and concludes that it has been a spectacular success, whatever its detractors may say. But he also has some advice to offer: the German government, he writes, should be … [Read more...]
