There are competing ideas on the best technologies to rapidly decarbonise the energy system. Some scenarios emphasise the role of carbon capture and storage to render coal- and gas-fired power plants more climate-friendly. Others point to nuclear energy and a third group is more optimistic on renewable sources. But itās plausible that even these more optimistic outlooks have greatly underestimated the potential of solar power, writes Dr Felix … [Read more...]
IEA underreports contribution solar and wind by a factor of three compared to fossil fuels
The International Energy Agencyās (IEA) statistics underreport the role of wind and solar in the worldās energy mix by a factor of three, writes Erik Sauar. This gives policymakers, investors and the public the false impression that wind and solar are insignificant. According to Sauar, the counting method must be changed to reflect how close the world really is to a transition to renewables. Article courtesy Energi og Klima. [See note at the end … [Read more...]
The perils of falling in love with energy technology
Renewable energy and fossil fuel advocates have one thing in common ā 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...]
Study finds advanced nuclear reactors will have competitive costs
A new study of contemporary nuclear industry cost projections, previously unavailable to the public, provides new insight into a potential path breaking cost trend for the next generation of advanced nuclear plants, writes Dan Yurman, specialized nuclear energy reporter who runs the blog NeutronBytes. … [Read more...]
Nuclear and coal lobbies threaten to scupper renewables in South Africa
South Aricaās state utility Eskom is undermining the development of renewable energy in South Africa, writes Professor Hartmut Winkler of the University of Johannesburg. According to Winkler, the countryās coal and nuclear lobbies are behind the opposition to renewables. The struggle is part of a wider political confrontation over control of key parts of the South African economy. Courtesy The Conversation. … [Read more...]
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 GƶĆ. … [Read more...]
Legal challenge to Spainās capacity market payments well-founded
Two Spanish NGOās have started a court case against Spainās capacity market scheme, which they say unnecessarily subsidizes operators of large power plants for billions of euros. Gerard Wynn, independent energy consultant, explains why their arguments are well-founded. According to Wynn, Spainās capacity mechanism violates EU rules and should be scrapped as soon as possible. This article was first published onĀ the blog of the Institute for Energy … [Read more...]
The trillion dollar question: will renewables displace natural gas?
Bloombergās renewable energy affiliate forecasts that wind and solar power will make major inroads into the global market share of natural gas within a decade.Ā 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-pusher in Chief: Trumpās fossil-fueled foreign policy
Donald Trumpās efforts to promote fossil fuel consumption has become a defining theme of his foreign policy, writes Michael Klare, expert and author of many books on energy and foreign policy. Trumpās words and actions make that all too clear ā although the media and most commentators have so far failed to notice. Courtesy Tom Dispatch. … [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 carbon-capture dream is dying
The collapse of a Dutch āclean coalā power project has ended near-term prospects for carbon capture and storage (CCS) in European power generation. That leaves proponents of the technology having to turn instead to smaller, industrial applications, writes energy analyst and consultant Gerard Wynn. But while CCS may make sense on a more limited scale, big problems remain there too, he adds. This article was first published on the blog of the … [Read more...]
Is energy ādominanceā the right goal for U.S. policy?
In recent weeks, a new energy buzzword has taken flight from Washington, D.C., making stops in Alaska, North Dakota, Texas, Utah and more: āAmerican energy dominance.ā But according to Daniel Raimi, senior research associate at the University of Michigan, this goal is unrealistic and it distracts from the goals that should be shaping U.S. energy policy. Courtesy The Conversation. … [Read more...]
Is the U.S. close to achieving energy dominance?
If you hadnāt heard, the Trump Administration declared last week to be āEnergy Weekā, a week during which the President and his senior officials were focusing on the theme of āU.S. Energy Dominance.ā Not āenergy independenceā or āenergy securityā, both themes past presidential administrations have focused upon. David Blackmon looks at what this means. Article courtesy Oilprice.com. … [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...]
Finkel Review, blueprint for Australiaās electricity market: āthe real work has still to be doneā
The blueprint for Australiaās future electricity market released recently by Australiaās chief scientist Alan Finkel pleases some but not all market watchers, writes Fereidoon Sioshansi, publisher of the newsletter EEnergy Informer. For some critics, the real work on climate and energy policy in Australia has still to be done. … [Read more...]
