The UK transition is often cited as a success story. Coal’s contribution has dropped from 40% to 6%. Wind, solar and hydroelectric now generates more electricity than nuclear. Demand for electricity has also fallen. The carbon intensity of Britain’s electricity has almost halved, from over 500g of CO₂ per kilowatt-hour in 2006 to under 270g in 2018. The National Grid now expects to be able to operate a zero-carbon electricity system by 2025. But … [Read more...]
Greece: lignite asset sale failure could shift focus to electricity market reform and renewables
This month Greece’s Public Power Corporation (PPC) admitted its effort to sell a third of its lignite assets had failed. Dr. Nikos Mantzaris, of the think tank The Green Tank, gives his explanation for why the numbers never added up for the buyers. He now fears the PPC will simply sweeten the deal. Instead, Greece should abandon failing lignite assets, reform the electricity market and refocus on renewables. … [Read more...]
Electric metering should break its link with power consumed and create it directly with the costs of delivery
In a world where electricity is generated from non-renewables (oil, gas, nuclear) our meters measure and charge us for electricity delivered, as if it was a fuel being consumed. Going forward, the cost should be measured against what is actually being consumed. In a renewables world – particularly 'run-of-the-river' hydro, wind and solar - that’s not the electricity. It’s the wear and tear on the infrastructure. Treating these types of renewable … [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...]
