Vehicle congestion charge zones are a way of taxing drivers for the emissions they create. They have great potential to steer polluters towards shorter and/or fewer journeys, and towards cleaner fuels. But these schemes have received too little attention among analysts. “Cordon zones” are found in big cities like London, Stockholm, Milan and Singapore and the rules are kept very simple. Journey length is rarely, if ever, taken into account. … [Read more...]
Avoiding renewables bottlenecks needs long term planning of electricity transmission infrastructure
As more renewables are rapidly added to grids, network operators must plan new transmission lines to integrate them immediately, avoiding wasteful bottlenecks. It’s a puzzle that’s getting bigger and more complex as the energy transition gains pace, which means transmission policy and planning must improve, and fast. Rather than making lots of small incremental steps, planning ahead will prove less costly and capture efficiencies and economies of … [Read more...]
Why was Nuclear side-lined at COP26?
James Conca is extremely disappointed that nuclear did not get a serious hearing by negotiators at COP26. Meanwhile in the "Green Zone" (for the general public), the World Nuclear Association had all of its members' applications to establish exhibits rejected. Why? If public opposition is a main obstacle, the nuclear industry should be given an opportunity to argue its case, explain how it is one of the safest energy sources available, and … [Read more...]
Corporations, Cities, Financial Institutions: can private collective action plug the global emissions gap?
Non-state actors - corporations, cities, and financial institutions – are making their own impact on emissions reductions. We don’t just have to rely on governments, explain James Newcomb, Jun Ukita Shepard and Laurens Speelman at RMI. Case studies of harnessing private collective action already exist, and they are significant. Take Power Purchase Agreements (PPAs). In the U.S., corporates ramped up annual renewables procurements from 0.1 GW to … [Read more...]
Fulfilling the Global Methane Pledge: “polluter pays”, more electrification, less gas
At COP26 the U.S. and the EU led a global pledge to slash methane emission by 30% by 2030. Methane makes up at least one-quarter of all greenhouse gases, and is more than 80 times more damaging than CO2 over a 20-year period. Success in cutting these emissions would be a major step towards meeting our 1.5°C goals. But far from declining, 2020 saw methane emissions grow at the fastest rate in 40 years. The increased use of natural gas (mostly made … [Read more...]
Renewed interest in Carbon Capture strategies for net-zero: targets, obstacles, costs, priorities
Martina Lyons at IRENA picks out the highlights of their new report “Reaching Zero with Renewables: Capturing Carbon”. Carbon capture is going to be expensive, so should be focussed on hard-to-abate industrial sectors, as well as bioenergy plants. Lyons breaks down the target carbon capture volumes, costs and the investments required, as well as looking at the consequences of different strategies and carbon prices. Scaling up this technology, … [Read more...]
When Electrification is cheaper than maintaining Gas infrastructure
The gas sector continuously faces major expenses to maintain and replace aging distribution systems. Non-Pipeline Alternatives (NPAs) are solutions that avoid the scale of these infrastructure costs by judiciously spending money on cutting future gas use instead. Given gas’s limited long-term future in a net-zero world, this makes sense. It’s not just about efficiency wins, explains Max Dupuy at RAP who summarises their research. Gas utilities … [Read more...]
Behaviour Change: strategies and case studies for reaching net-zero by 2050
Technological solutions on their own are unlikely to deliver emissions reductions at the speed and scale required to reach net zero by 2050. Daniel Crow, Insa Handschuch, Gabriel Saive and Leonie Staas at the IEA look at a suite of policy-driven citizen “behaviour changes” that should be used to bridge the gap. The impact will be greatest in advanced economies where energy intensity is highest. Meanwhile, in emerging economies the good habits put … [Read more...]
Surging U.S. renewables on track to take 30% market share by 2026
While the U.S. Congress debates whether backing the transition is a winning strategy, the energy sector is clearly showing the nation’s direction of travel. Dennis Wamsted and Seth Feaster at IEEFA look at the impressive growth of the clean energy champions, wind and solar. Since 2019, wind and utility-scale solar generation has risen by 76 TWh — a 31% increase — while coal and gas has fallen by 1.6%. By 2026, wind and utility-scale solar will … [Read more...]
CEPP incentives and penalties: current design could undermine U.S. clean energy growth
The Clean Electricity Performance Program (CEPP) is a key part of President Biden’s energy and climate plans. It will steer utilities towards clean energy with incentives and penalties, and is still being designed. Severin Borenstein and James Bushnell at the Energy Institute at Haas, Steve Cicala at Tufts University and Ryan Kellogg at the University of Chicago warn that current proposals will allow utilities to game the system, resulting in … [Read more...]
DoE study: 45% of U.S. power from Solar by 2050. How?
This month, the White House released a U.S. Department of Energy report, the Solar Futures Study, on how solar power could generate up to 45% of the U.S. electricity supply by 2050. It’s less than 4% today. Joshua Rhodes at the University of Texas at Austin looks at what obstacles must be overcome. The good news is that the technology and engineering is already available. And solar’s advantage is that the sun shines nationwide. Other region and … [Read more...]
Appliances and Equipment Efficiency Standards: energy savings rival total Wind & Solar generation
Don’t underestimate the effect of Energy Efficiency Standards and Labelling (EES&L) programmes for appliances and equipment, says the IEA. In other words, the gradual tightening of efficiency rules for things like refrigerators, ACs, TVs, washing machines, cookers, vending machines and other electronics. In the nine countries and regions measured (including the U.S., the EU and China), EES&L programmes reduced electricity consumption by … [Read more...]
The U.S. now needs a Carbon Tax to transition from Gas to Renewables
Gas emissions must be halved (and coal eliminated) by 2030 to meet President Biden’s goal of a carbon free power sector by 2035. The problem is that gas additions are half the price of new wind and solar installations. Though the clean energy champions are still getting cheaper, so are gas additions. Nikos Tsafos at the Center for Strategic and International Studies looks at the policy options over the next decade for the U.S. The stark fact is … [Read more...]
Energy-efficient and affordable housing will increase public support for the Green Deal
Energy poverty – the inability to afford basic household energy needs – affects up to one-third of U.S and European households. The energy transition can be part of the solution, says Clare Taylor. Targeted energy-efficient retrofits and newbuilds for low-income households will cut bills and improve living conditions. This will not only cut emissions, but get the beneficiaries behind wider climate change policies like the Green Deals in Europe … [Read more...]
Can full-scale Distributed Solar really save $473bn in grid investments?
A giant model of the entire US electricity sector which captures distributed energy resource (DER) potential has been getting a lot of attention. It estimates that distributed solar and storage can save $473bn in system-wide costs when deployed at scale (enough to power more than 25% of US homes). Rooftop solar is definitely much more expensive than grid generation, but its location (on your own roof) avoids a range of costly transmission and … [Read more...]
