Bans on subsidies (in some countries) and reduced costs have hit total investment in onshore wind. Meanwhile, market share continues to grow across the EU28. Wind energy now accounts for almost 20% of installed capacity for power generation which makes researcher Schalk Cloete's sobering analysis of risks for onshore wind well worth reading. Following up on his previous article, he examines current assumptions and argues that the discount rate … [Read more...]
An evening with ecomodernist Michael Shellenberger (or: a defence of nuclear power you have not heard before)
Pro-nuclear activist Michael Shellenberger, founder of the California-based global citizens movement Environmental Progress (ânot paid by the nuclear industryâ) was in Amsterdam recently, where he gave a very personal âEcomodernistâ defense of why nuclear power is good and how it should be supported. âIt is about protecting the natural environment by concentrating human activity.â This article was first published on Energy Post Weekly. … [Read more...]
DNV GLâs Energy Transition Outlook shows massive shift of investment from oil and gas into power lines
The global energy transition will lead to a massive expansion of power lines at all voltage levels as well as a steep growth in the number of transformers and substations in the electricity system. This is one of the major new findings of the second edition of the Energy Transition Outlook, the annual flagship publication of global technical consultancy DNV GL. As a result, grid costs will triple, yet this cost explosion is offset by cost … [Read more...]
Tipping point: new wind and solar competitive with existing coal and gas
âŹ20/ton carbon prices in combination with high coal and gas prices have created a new tipping point in Europe, writes Dave Jones of UK-based think tank Sandbag. For the first time, new onshore wind and solar can compete with existing coal and gas plants. … [Read more...]
The celebrity couple: intermittent renewables and electric cars
Even though storing intermittent wind and solar power in electric car batteries sounds attractive, this will be impractical and expensive in practice, writes Schalk Cloete. Electric cars have much clearer synergies with baseload power plants, while excess wind and solar power is better suited to H2/synfuel production. … [Read more...]
Energiewende enters a new phase â how is it performing?
The Energiewende is proceeding ahead of schedule with high grid reliability, writes researcher Schalk Cloete. However, costs are much higher than originally planned, while CO2emissions are stagnating. According to Cloete, wind/solar market shares have now reached the point where large grid expansion projects become critical. One problem is that the net value of new wind/solar is approaching zero as market value declines and integration costs … [Read more...]
How rapidly can we transition to 100% renewable electricity?
Science tells us that, to avoid devastating climate change, we must rapidly cut greenhouse gas emissions to zero. How fast is possible, asks Mark Diesendorf  of the Cooperative Research Centre for Low Carbon at the University of New South Wales (UNSW) in Australia. He believes the sceptics may be wrong. … [Read more...]
The ice beneath the EU-China climate bonhomie
When it comes to clean technology, German chancellor Angela Merkel views China no longer as a developing country but a competitor, writes Karl Mathiesen of Climate Home News. From a European perspective, China is joining the club of industrialised countries, competing for their markets, and should be treated as such. Courtesy Climate Home News. … [Read more...]
Exclusive interview Mark Gainsborough, head Shell New Energies: âWe are further along than people realizeâ
With a string of new investments and acquisitions in the past year (you can find a unique overview further on in this article!), Shell has quietly stepped up the pace of its transition from an oil and gas company into an energy company. âWe are further along than people realizeâ, says Mark Gainsborough, Executive Vice-President of Shell New Energies, in an exclusive interview with Energy Post. According to Gainsborough, there is a âshift in … [Read more...]
Ukraineâs power sector is set for a major transition
As the pillars of Ukraineâs power sector â coal and nuclear â are shaking, the country is on the point of a major energy transformation, writes Oleg Savitsky, climate and energy policy expert and journalist. But some crucial steps still need to be taken to make it possible. … [Read more...]
Uneconomic coal could be squeezed out of European Union power markets by 2030
Coalâs time is running out in Europe: deteriorating economics and stronger climate policies will soon make coal uneconomic, writes Silvio Marcacci of think tank Energy Innovation. Many European countries have already set an end date for coal power, utilities and investors are shifting away from it. The question is not if coal will lose, but when, and how well-managed its exit will be. … [Read more...]
Why there is so much aggressive bidding at renewables auctions â and what the risks are
Renewable energy auctions have seen very low prices in many parts of the world. Why do auctions seem to be so effective in driving down costs â and what are the risks? Ana Amazo-Blanco, Silvana Tiedemann of Navigant[1], and Dr. Stephen Tay and Monika Bieri of SERIS looked at a solar PV rooftop auction in Singapore and an offshore wind auction in Germany to discover the key factors behind the bids and suggest how project developers can make sure … [Read more...]
A common goal for all sustainability advocates
Nothing is better for fossil fuel interests than current government policies supporting wind, solar and electric cars, writes independent researcher Schalk Cloete. These green technologies won't reduce fossil fuel consumption sufficiently for a long time to come, so the fossil fuel sector will be able to survive that much longer. In the third and last part of a series on green technology-forcing, Cloete calls on all sustainability advocates to … [Read more...]
Planned Kosovo lignite power plant fails to commit to cleaner technologies
London-listed, global energy investor ContourGlobal portrays its plans for a new coal power plant in Kosovo as a step towards cleaner air, but its legal agreement with the government shows that it fails to commit to best-in-class environmental performance, writes energy finance consultant Gerard Wynn. Courtesy Energy and Carbon blog. … [Read more...]
Is offshore wind about to hit cost-competitiveness in the U.S.?
Offshore wind may seem like a pricey option, but itâs actually an extremely valuable investment, writes Mike OâBoyle of San Francisco-based think tank Energy Innovation. According to a new analysis, the market value of electricity generated by offshore wind will soon exceed its cost in New York and several New England states. … [Read more...]
