BEIS is optimistic about UK energy future

The UK governments new projections for renewables are very optimistic- its claimed that there coud be 45GW in place by 2035. That might supply up to 50% of power by 2035. But its policies on the ground seem to undermine this optimism- on shore wind, the cheapest renewable, is being blocked and PV is being constrained. New options, like tidal lagoons, are also stalled or struggling. CCC, RAE and others have called for urgent action to avoid a shortfall.

EU Renewables Policy: mixed reactions

EU renewable energy policies have impacted on member states in various ways and they have responded in various ways, some being more enthusiastic than others, as is explored in two new books that also look in detail at implementation and legislative issues.

A ‘gross’ miscalculation

Energy data are sometimes presented in terms of primary energy fuel inputs. This may make sense for fossil fuels but not for renewables or nuclear. And grossing up their outputs, to give a virtual primary input, as if the output was generated by fossil fuels, is an odd approach. Better just to use outputs for everything. Although in the case of Bitcoin applications, the energy input, however measured, looks likely to be huge.
