This week the European Commission tabled the Energy Performance of Buildings Directive (EPBD) which should accelerate the decarbonisation of buildings. Buildings and cities play a key role in the energy transition. And the target high shares of variable renewable power supply will be much more easily achieved if the sectors using them display demand flexibility. In essence, that means using or storing the excess wind and solar generation … [Read more...]
Politicians need net-zero scenarios that include socio-economic obstacles and solutions
Standard net-zero scenario modelling carefully analyses the possible impacts of technological solutions and their obstacles. What theyâre missing is the detailed analysis of the socio-economic impacts of these scenarios on the lives of citizens. That means jobs, incomes, energy bills, air quality, and regional economic performance. In other words, the politics on the ground. Misunderstood, and perfectly sensible pathways will come up against … [Read more...]
Climate change, âwind droughtsâ and the implications for Wind energy
What effect will changing trends in regional wind speeds have on the future of wind energy? Very large, considering that a small change in wind speed has a big effect on the power output of a turbine (itâs related to the cube of the wind speed). Hannah Bloomfield at the University of Bristol first looks at the âwind droughtâ experienced in Europe this year which saw SSE in the UK report a 32% drop in power from its renewable assets. Meanwhile, … [Read more...]
How multi-scenario âemulatorâ models are improving climate change projections
State-of-the-art Earth System Models (ESMs) simulate the flow of energy, moisture and chemicals through the atmosphere, ocean and land surface in unprecedented detail. But the data processing is so demanding that each scenario takes considerable time and expense to run, needing powerful supercomputers and teams of scientists and programmers to produce the models and analyse the results. âEmulatorsâ are much simpler models that can run on a … [Read more...]
