Todayâs technologies â wind, solar, storage - have widely differing cost and operating characteristics to fossil fuels. So the way customers are made to cover those costs â assigning different rates to different customer classes â should change. Jim Lazar and Mark LeBel at RAP explain why and how, referencing their comprehensive manual âElectric Cost Allocation for a New Eraâ. They describe how the full range of technologies now establishing … [Read more...]
Three U.S. utilities to skip the gas âbridgeâ, move straight from coal to renewables
At the end of June, utilities in three U.S. states declared they are closing down coal plants and moving straight to renewables, without building new gas plants as a âbridgeâ fuel. For example, to replace lost coal capacity, Tucson Electric Power in Arizona will add 2,457MW of new wind and solar generation, backed up with 1,400MW of battery storage. Similar commitments are being made by other utilities in Colorado and Florida. New Mexico is … [Read more...]
BPâs world energy review: 2019 saw clean electricity match coal
Simon Evans at Carbon Brief summarises BPâs 69th edition of its influential annual statistical review of world energy, looking at 2019. Overall, total energy demand rose, though slower than usual. Renewables were the largest source of new energy, but were closely followed by oil and gas. Coal use dropped again, the fourth drop in six years, thanks to historic declines in the EU and the US. But continued growth in SE Asia, China and India leaves … [Read more...]
The PAC Scenario: net-zero by 2040 to meet Europeâs Paris goals
The EU is not on track to meet its Paris Agreement obligations on emissions and limiting the global temperature rise to 1.5°C. CAN Europe and the European Environmental Bureau (EEB) present their Paris Agreement Compatible (PAC) scenario, designed to do just that. Itâs been created through the careful analysis of contributions from more than 150 stakeholders including NGOs, scientists, industry and grid operators. Jörg MĂŒhlenhoff at CAN Europe … [Read more...]
âGreenâ chemical plants that ramp up and down with wind, solar
One solution to variable renewables is to create customers that have no problem with ramping up and down production along with the power. In fact, when the wind and solar is producing too much power for the grid it can be bought very cheaply, making intermittent customers very happy. Jim Conca describes a new design for a Chlor-Alkali Chemical Plant that can âidleâ without critical components of the plant degrading â the main reason for a plant … [Read more...]
Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?
History shows a disruptive technologyâs tipping point can be under 5% of market share, thatâs all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]
Energy Post panel discussion – Cross-Border Capacity [VIDEO]
Whilst renewable generation continues to grow, cross-border capacity fails to keep up. On May 19, 2020, Energy Post hosted a unique panel qualified to discuss the issue and shed some light on how we got here and what the options might be going forward. The discussion was moderated by Erik Rakhou - alternate member of the ACER board of appeal and consultant at Baringa. Representing the European Commission was Florian Ermacora and for independent, … [Read more...]
Negative electricity prices: lockdown’s demand slump exposes inflexibility of German power
The lockdown has unexpectedly allowed us to model certain aspects of the energy sectorâs possible future. One is the oversupply of variable renewables into the grid. In Germany, a slump in demand plus an exceptionally sunny and windy few months sent wholesale electricity prices negative and to record lows. Fossil generators calculated that paying buyers to take electricity was cheaper than performing a shut-down re-start sequence, so they did … [Read more...]
Clean Energy threatened by lockdown of critical minerals supply
Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric transport and grid storage are now the largest consumers of lithium and cobalt. Examples of rising consumption abound for other … [Read more...]
Recyclable Wind Turbine Blades: thermoplastic, next-generation
When wind turbine blades are decommissioned they are usually scrapped and thrown into landfill because they cannot be recycled. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades. As wind installations increase so will that number. It's because most blades are constructed from epoxy or other thermoset resins. So National Renewable Energy Laboratory (NREL) researchers are using a thermoplastic resin, … [Read more...]
IEA projections 2020: energy demand plunges but Renewables still grow at Gas, Coalâs expense
The IEA has made its projections for the impact of the pandemic lockdown on energy demand in 2020 (they say itâs too early for them to assess anything more long term), and its implications for the different generation types. This article summarises their special Global Energy Review 2020, published at the end of last week. It assumes that lockdowns are eased this year and growth gradually returns. With that, global energy demand will fall 6% in … [Read more...]
IRENAâs Global Renewables Outlook and how Europe can lead the way
If the coronavirus slump has knocked everything off track IRENAâs first ever Global Renewables Outlook is a timely reminder of what that track should look like. It can help policymakers design stimuli packages that will get us back onto it, and even accelerate the transition. IRENAâs Gayathri Prakash, Nicholas Wagner and Ricardo Gorini run through the comprehensive reportâs main recommendations. Annual investment, shares and GW targets to 2030 … [Read more...]
Bounceback or Recession? Modelling the impact on electricity prices to 2025
Carlos Perez Linkenheil at Energy Brainpool models three scenarios to understand the factors that are having the biggest impact on â and thereby make predictions for - electricity prices, revenues, energy source merit order, and emissions in the EU. Other parameters in the scope of their analysis include oil prices, gas prices, commodities markets, carbon taxes, and the EUA/emissions market. Clearly, collapsing prices are profoundly distorting … [Read more...]
U.S.: Counting Renewables jobs and projects under threat, what can be done and why
All sectors across all economies are trying to add up their potential job losses and projects in jeopardy, then telling their governments to prioritise them for Covid lockdown support. Mike Jacobs at the Union of Concerned Scientists looks at renewables in the U.S. He quotes news reports that over 100,000 workers in this fast-growing industry filed for unemployment in March 2020. On top of that, the already planned expiry and phase-down of … [Read more...]
Designing the Covid-19 stimulus: what the 2008 crisis can teach us
Policy makers around the world are hearing a lot of advice on how to design their stimulus packages. This comes from the IEA where Fatih Birol lays out five fundamental lessons we can learn from the stimulus packages that came out of the 2008 global financial crisis. His main headings are: Build on what you already have â and think big (e.g. feed-in tariffs, production tax credits); Choose technologies that are ready for the big time (e.g. wind, … [Read more...]
