Renewable energy and fossil fuel advocates have one thing in common – an unhealthy tendency to fall in love with a particular energy technology, writes Hal Harvey, founder and CEO of think tank Energy Innovation. Policymakers for their part often fall in love with particular policies. But according to Harvey, what matters is setting ambitious goals, adopting policies that reward performance and let the dynamics of the market work out how to get … [Read more...]
How electricity will be priced in the future
The rapid transformation of the electricity sector will make it necessary for utilities to adopt radically new pricing methods, writes Fereidoon Sioshansi, publisher of newsletter EEnergy Informer and editor of a new book, Innovation & Disruption at the Grid’s Edge. According to Sioshansi, existing volumetric tariffs will increasingly be replaced by fixed service fees. … [Read more...]
The renewable energy auction revolution

Trends in electricity prices in Europe: expect more volatility
Electricity prices in Europe will become volatile, variable renewable energy will grow but will still be supplemented significantly by conventional power plants. These are of some of the main outcomes of the power price scenario EU Energy Outlook 2050, released by Energy Brainpool. One of the major question marks for the power sector will be the development of e-mobility, write Carlos Perez-Linkenheil and Simon Göß. … [Read more...]
Politically charged: do you know where your batteries come from?
People are excited about batteries, from electric cars to Tesla’s 129 megawatt-hour energy storage project  in South Australia. But one important issue is often overlooked: the raw materials needed to build this technology – where they come from and their environmental cost. Ben McLellan of Kyoto University takes a closer look at what goes into the lithium-ion battery. Article courtesy The Conversation. … [Read more...]
The trillion dollar question: will renewables displace natural gas?
Bloomberg’s renewable energy affiliate forecasts that wind and solar power will make major inroads into the global market share of natural gas within a decade. This is a crucially important question for major oil companies who are betting their future on gas, writes Managing Director of independent US-based consultancy GSW Strategy Group Geoffrey Styles. But according to Styles, it is likelier that coal, not gas, faces the biggest risk from the … [Read more...]
Carbon capture and storage: too expensive for reducing power sector emissions
The hope that carbon capture and storage (CCS) can ever play a significant role in the reduction of power sector emissions is misplaced, write Jeffrey Rissman and Robbie Orvis of Energy Innovation, a San Francisco-based energy and environmental policy think tank. Coal-fired power is already more expensive than unsubsidized onshore wind and solar PV. Adding CCS will only increase this gap. The subsidies required to bring CCS costs in line with … [Read more...]
Startup spotters Freerk Bisschop (Rockstart) and Evert Jaap Lugt (Yes!Delft): “Smart meters are already obsolete”
Freerk Bisschop, Director Smart Energy at Rockstart, and Evert Jaap Lugt, Managing Director at Yes!Delft, talk about what they look for in contenders for the New Energy Challenge – and for their own startup programs. They also spotlight some of the trends going on in energy innovation and call on established industry and policymakers to get more involved with startups. “Everything is changing so fast. Things like smart meters are already based on … [Read more...]
The surprising New Energy side of Shell
“With Shell Technology Ventures we position ourselves strategically in many places, so that we can experience first-hand where the energy ecosystem is going, and create options for the future”. An interview with Geert van de Wouw, Managing Director of Shell’s venture capital unit, part of the company’s New Energies division, shows the fascinating new side of the old oil company. Quietly, Shell is getting ready to become a major player in a wide … [Read more...]
Energy wonks have a meltdown over the US going 100 percent renewable. Why?
In the U.S. a furious debate has erupted among academic energy experts about whether the country could run 100% on renewable energy. Joshua D. Rhodes, Postdoctoral Researcher of Energy at the University of Texas, Austin, explains what is going on and offers some thoughts of his own. Courtesy The Conversation. … [Read more...]
Germany’s first renewables auctions are a success, but new rules are upsetting the market
The introduction of renewables auctions in Germany, replacing administratively set feed-in premiums, has led to considerably lower prices and very high realization rates. However, community participation was very low in the first solar PV auctions. Now a new rule favouring community projects in onshore wind auctions turned out to be so attractive that most bidders created community projects to profit from them. This is turning the market upside … [Read more...]
EU’s Mediterranean neighbours struggle with energy transition
Taking a cue from the EU, members of the Arab League have adopted renewable energy and energy efficiency plans and targets. But they lack incentives and a stable policy framework to drive growth. “There are local initiatives, but no process to underpin an energy transition”. … [Read more...]
To slow climate change, India joins the renewable energy revolution
India has embarked on a remarkable renewables revolution, made possible by falling prices of solar power, writes Arun Agrawal, Professor of Natural Resources and Environment at the University of Michigan. According to Agrawal, what is needed above all to make the energy transition succeed, is robust grids and careful land use planning. Courtesy The Conversation. … [Read more...]
Are solar and wind really killing coal, nuclear and grid reliability?
U.S. Secretary of Energy Rick Perry wants to know whether solar and wind are killing coal, nuclear and grid reliability. Thanks to Texas, where Perry was governor, we know that a combination of wind and solar with fast-ramping natural gas, smart market designs and integrated load control systems will lead to a cleaner, cheaper, more reliable grid, write four researchers at the University of Texas. Courtesy The Conversation. … [Read more...]
Pitting wind and solar against nuclear power
With US electricity demand stalled, expanding wind and solar power is increasing the economic pressure on equally low-emission nuclear power, writes Geoffrey Styles, Managing Director of independent US-based consultancy GSW Strategy Group. He notes that the beneficiaries of renewable energy subsidies resist new state incentives for nuclear plants. But according to Styles, wind and solar should not come at the expense of nuclear power, as all are … [Read more...]
