Integrated renewables- the cheapest option IRENA has develop a new energy costing system and found that renewables plus storage could supply firm power at low system costs- see my earlier post . Another new metric for assessing the total levelized cost of energy (LCOE) has also emerged with equally striking results. It puts the costs of a mix of offshore wind & solar at about €46/MWh in a future climate-neutral energy system for Denmark- less than half the equivalent cost of nuclear under the same conditions. Thats the conclusion of a new multi-authored peer reviewed study with inputs from Denmark, Finland, Chile, Croatia and the UK. It introduces a new system-based LCOE metric - referred to as SLCOE. It says that ‘while the LCOE is only a function of the respective technology, the SLCOE is a function of both the technology and the energy system context in which it operates’. It shows that ‘the SLCOE of wind power and solar photovoltaics can be much lo...
Some changes are afoot with Renew and NATTA, so here’s a short update, along with a retrospective account of their long history. The normal Renew extra weekly news service will return with the next issue. In 1976, along with colleagues from the Open University Faculty of Technology, I helped organise a conference on alternative energy held at Cranfield University. It attracted about over 50 people from around the UK and led to the establishment of NATTA, the Network for Alternative Technology and Technology Assessment, which I then led. Alternative Technology- what’s that? Basically, it means wind, solar, and other sources of renewable energy - then something of a novelty but now commonplace. And NATTA played a role it making that happen. It started out by organising follow up conferences around the country and, in 1979, setting up a bimonthly membership newsletter. That expanded and became ‘Renew’ which I have run bimonthly, in various formats, to this day . The ...
