Carbon offset programmes rightly get a lot of criticism. There’s plenty of evidence of offsets not delivering all the GHG emissions reductions they are credited for. Though still on the international agenda, should they be ditched? Or can they be improved with better analysis and evaluation, and making that a pre-condition for creating carbon offset credits, asks Meredith Fowlie at the Energy Institute at Haas. She starts by looking at those … [Read more...]
California: Designing electricity rates that are fair and encourage EV and Heat Pump take-up
Electricity prices in California are not fair and not good for incentivising electrification, says James Sallee at the Energy Institute at Haas, because of the way people are being billed. There is no doubt that electrification (grid upgrades, etc.) and climate mitigation (including controlling California’s wildfires caused by power cable failures) must add to the cost of transition. But Californians can now find themselves paying up to twice the … [Read more...]
Case studies: Strategic EV funding starts with an Essential Charging Network
Building a nationwide EV charging network is a daunting prospect. Camille Kadoch and Julia Hildermeier at RAP look at those places that are being strategic about it, starting with an essential network that will allay the concerns of consumers on the verge of buying an EV but put off by worries that they will get stuck somewhere with a flat battery. That’s frustrating, given the average American drives only 37 miles a day and Europeans 32 … [Read more...]
Are EV owners driving less than we thought?
Research from California, the EV leader in the U.S., suggests that EV owners drive their vehicles half as much as the average gasoline car owner. Catherine Wolfram at the Haas School of Business explains that their research project reveals mileage data is so hard to gather that it’s difficult to know what’s actually going on. Is the data wrong (they don’t think so), or are EVs only being bought by drivers who don't use a car much? If so, the … [Read more...]
New Berkeley Lab Report Documents Trends in System Impacts, Reliability and Market Value of Solar in the United States
By Andrew Mills and Joachim Seel, Berkeley Lab As solar generation increases, it is expected to progressively impact the bulk power system—changing prices for energy and other grid services. Solar generation is driven by sunshine and thus often highly correlated over the course of a day within a region. Without the deployment of storage or an increase in price-responsive load, growth in solar capacity is … [Read more...]
We’re making much more progress decarbonising Electricity than Transport. Why?
In the OECD, since 2000, electricity sector emissions have fallen by 8% while transport emissions have actually increased by 5%. The best performers like the UK recorded drops in both: 40% and 6% respectively. In the U.S. it’s 25% and 0%. Catherine Wolfram at the Haas School of Business asks why transport is still going in the wrong direction, given the power sector’s progress. She posits three theories. Rich nations are outsourcing … [Read more...]
Rolling out EV charging infrastructure beyond cities
“Range anxiety” causes people not to buy EVs because they’re afraid they won’t be able to travel very far if charging facilities don’t extend beyond metropolitan centres. Jimmy Gilman at RMI describes their study of what infrastructure exists on the outskirts of U.S. cities, and at tourist destinations and airports outside the cities. 60 cities, encompassing more than 57% of the U.S. population, have been given scores. The coastal areas perform … [Read more...]
A pathway for profitable CCS in California
A study from the energy departments of Stanford University, from where Kara Glenwright writes, lays out a pathway for California to capture and store up to 60 Mt (million tonnes) of CO2 a year. 76 site locations have been identified where work could start immediately to store 20 Mt/yr profitably under the existing low carbon rules. But first a raft of clarifications on the laws is needed, showing that the success of CCS doesn’t just depend on the … [Read more...]
E-Trucks need infrastructure, not just cheaper batteries
The electrification of road freight has great potential, but there are some big gaps that first have to be bridged. Writing for IRENA, Dolf Gielen, Francisco Boshell, Guy Lentz and Sita Holtslag explain what needs to be done to ensure that the technological advances and cost reductions happening at the forefront of e-mobility are quickly delivered onto our roads. To illustrate the problem: in Europe over half of road freight is transported less … [Read more...]
Enhanced Weathering: crushed rocks spread on farmland can capture billions of tons of CO2/year
Enhanced Weathering is a carbon capture process that could remove over 2bn tons of CO2 each year (for comparison, the U.S. emitted 5.3bn in 2018), explains Benjamin Houlton at the University of California. Silicate minerals exposed to the weather have been sequestering atmospheric carbon and turning it into rock since the dawn of time, but it’s a process that normally takes thousands of years. This period can be cut to two years by grinding … [Read more...]
California learns even flexible Emissions Markets won’t guarantee price stability
In May, emissions allowance prices hit rock bottom in California. How can cap-and-trade work properly when prices are so volatile and difficult to predict? It makes life very difficult for businesses and investors, not to mention the state. Changes to the rules are being proposed to introduce more flexibility into the effective price floors, ceilings and the availability of allowances. But Severin Borenstein at the Energy Institute at Haas … [Read more...]
How to cut Full Life-cycle Buildings Emissions
Most efforts to decarbonise buildings are focused on “operational” emissions. That’s because, once constructed, buildings are responsible for a massive 30% of global final energy use and 28% of carbon emissions. But that focus has meant the “embodied” carbon – from the materials, construction, demolition, and recycling of buildings – has received little attention, explain Meng Wang and Yihan Hao at RMI. That’s despite the numbers still being … [Read more...]
Re-shaping the EU ETS as a safety net, not a driver
The EU ETS (Emissions Trading System) has struggled to cope with the current economic crisis which has caused a drop in the European carbon price, while the expected drastic drop in 2020 emissions will only add to the existing surplus of allowances. This highlights how necessary it is to reform the mechanism for managing this surplus or even to implement a carbon floor price, explain Charlotte Vailles at I4CE and Nicolas Berghmans at IDDRI. They … [Read more...]
Free online Buildings Electrification training for workers on lockdown
More than 26 million Americans have filed for unemployment benefits during the lockdown. Among their number will be workers who, while sitting at home, could be trained up with useful skills they can use when the lockdowns end. You just need to identify where the big skills gaps in the economy are. Stephen Mushegan and Claire McKenna at RMI look at buildings refits and electrification, where like in most countries huge emissions reduction targets … [Read more...]
The coalition for an EU-ETS carbon price floor is reaching critical mass
The EU Emission Trading Scheme (EU-ETS) is bound to play a major role for ratcheting up climate policies in both the EU and its member states. After a prolonged period of low prices that questioned the ETS’s viability, the recent price run upwards in the wake of a major reform has sparked confidence that from now on “everything goes in the right direction”. But this confidence is misguided and ignores major risks for the scheme, argue Michael … [Read more...]
