Weather forecasters are used to – and very good at – predicting large-scale weather patterns and then inferring what the actual surface weather conditions will be, based on a database of past events. Hannah Bloomfield at the University of Reading explains how the creation of a database of site-specific wind and solar generation, as well as grid demand, can be used it the same way to more accurately predict the impact of the weather on these … [Read more...]
Modelling total costs for Onshore Wind power plants: from site prep to grid connection
The costs of wind turbines is dropping. But that means all the other capital costs - site preparation, foundations, infrastructure, tower construction – will become a bigger part of the total. In the U.S. they currently account for around 30% of the capital expenditures needed to install a land-based wind plant. To keep those costs under control the National Renewable Energy Laboratory (NREL) has created a comprehensive open-source modelling … [Read more...]
Britain has shifted 30% of its electricity away from fossil fuels in just nine years
Britain’s extraordinary energy transition is in part down to increased energy efficiency: put simply, less electricity was needed, whatever the source. But coal is still essential during spikes in demand. Given coal generation is due to be phased out by 2025, the country will need to find alternative power sources to cope during extreme weather events. And that overall decline in electricity demand is sure to be reversed as more vehicles and … [Read more...]
