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...]
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...]
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...]
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...]
Jobs? Investing in renewables beats fossil fuels
For policymakers who are interested in job creation, investing in renewable energy is considerably more effective than investing in fossil fuels, writes Allan Hoffman, author of the blog Thoughts of a Lapsed Physicist and formerly with the U.S. Department of Energy. Solar and wind are powerful engines of job creation and economic growth. … [Read more...]
China’s continuing green shift in electric power: evidence from 2016
Over the past decade, China has been greening its electric power system faster than any other industrial power. But China is also continuing to pump out more greenhouse gases than any other other country. Is its green transformation happening fast enough? Hao Tan and John A. Mathews dig deep into the 2016 data and present an awesome picture of the stunningly large Chinese electric power sector. Courtesy Asia-Pacific Journal. … [Read more...]
Interview Ditlev Engel, CEO DNV GL Energy: “The biggest challenge is integration”
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...]
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...]
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...]
