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 (“not paid by the nuclear industry”) was in Amsterdam recently, where he gave a very personal “Ecomodernist” defense of why nuclear power is good and how it should be supported. “It is about protecting the natural environment by concentrating human activity.” This article was first published on Energy Post Weekly. … [Read more...]
DNV GL’s 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
€20/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 – 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...]
