Ditch climate arguments: they won’t help nuclear revive

By Dave Elliott

Steve Kidd, one time leading nuclear lobbyist with the World Nuclear Association, has had a rethink and left the WNA. In an article in Nuclear Engineering International he says ‘we have seen no nuclear renaissance’ and he outlines his new view- which is that the nuclear industry is in trouble and should stop using climate change arguments in its lobbying.

Capacity Market – the first UK auction

By Dave Elliott

In a fully free-market energy supply system there is no direct commercial incentive for generation companies to ensure that the lights stay on long term, by investing in new and/or backup capacity. Given that some old plants are scheduled for closure and more reliance on sometimes variable renewables is planned, the UK government has stepped in to create a new ‘capacity market’ to try to fill the potential gap in terms of reserve capacity and grid balancing capacity.

Energy return on energy invested

by Dave Elliott

There is inevitably some energy ‘embedded’ in energy generation systems, and it is useful to compare the energy needed to build and run plants relative to the useful energy out, but estimating ‘Energy Returns of Energy Invested’ (EROEIs) can be tricky. The ratios can range up to 200:1 or more, and down to single figures- very worryingly since then it is hardly worth running the plant.

A resurgence in net energy research: special issue online in Sustainability

By Carey King

There is a new special issue of the online open-access journal Sustainability on the
topic of net energy: New Studies in EROI (Energy Return on Investment). This has been organized over the last year by Charles Hall of the State University of New York. This special journal edition has many papers on new and updated assessments of EROI for oil and gas in the US, Canada and Norway. Additionally there are new papers discussing how to relate EROI to energy prices and costs as well as how different constructs for EROI measures (e.g. for a technology or a business) are useful for different decision making contexts.

I encourage all researchers and interested persons to view the papers in the special issue, as it is certainly a great contribution to the literature at a time when distinguishing among the most viable energy resources has never been more important.
