Prices on the European gas market have fallen sharply since August 2022 and Europe’s gas storage facilities are almost full. That’s good news, but the problems aren’t over. Simon Göss at cr.hub, writing for Energy Brainpool, explains why by looking at the data. He runs through the main factors driving the changes, primarily strong LNG imports, Norway’s increased production, mild weather, and lower gas consumption (particularly in industry). … [Read more...]
Electricity market re-design should focus on the root cause of the crisis, Europe’s dependence on fossil fuels
Amidst the perfect storm of the pandemic, war in Ukraine, and extreme weather events, Bruce Douglas at Eurelectric urges us all not to lose focus on our decarbonisation targets. Energy savings, electrification and renewables are more important than ever to help reduce dependence on fossil fuels. Douglas explains that Europe’s electricity sector remains totally committed to the drive towards clean energy, citing examples. He summarises the … [Read more...]
Next-gen Solar farms that work at night, in the rain, and self-clean
With the worldwide roll-out of solar, raising the efficiency of energy conversion isn’t just about the materials science of PV cells. Douglas Broom, writing for the World Economic Forum, runs through three “add-on” innovations. Researchers have found a way to generate electricity in the dark as panels cool during the night. A low-cost thermoelectric generator works using the temperature difference between the cooling solar panels and the … [Read more...]
Imagine it’s 2030 and net-zero is on track. How did we do it?
Imagine it’s 2030. The energy transition is on track and net-zero goals are entrenched across the global economy. How did we get there? Tim Buckley at IEEFA imagines it for us and sends us a postcard from the future. Writing in the past tense, he flags actual events and policies happening today to “remember” the major changes that took place to achieve it. Weather-related disasters compelled governments to act, recognising – apart from the … [Read more...]
IEA WEO 2021 message to COP26: 40% of clean energy goals will cut costs
The IEA’s latest World Energy Outlook was published on Wednesday. This year’s WEO-2021 is released earlier than usual to inform COP26 and, for the first time, is available for free to ensure the widest possible audience. Simon Evans at Carbon Brief offers his summary of the 386-page report, quoting relevant numbers and charts. He first points to the new scenario, Net-Zero Emissions by 2050 (NZE), as the IEA’s recognition that this is what … [Read more...]
Optimising Wind and Solar needs new ways of weather forecasting
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 in 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...]
