The debate is intensifying over how to decouple power prices from the extraordinarily high natural gas prices in Europe. Simona Benedettini and Carlo Stagnaro warn that the current problem of high prices is not caused by the mis-functioning of electricity markets, but by the exceptional trend in gas prices. So should the markets be re-designed at all? Will we lose the benefits of the current design, one being the reliable profits that renewables … [Read more...]
Is a Carbon Tax the best way to decarbonise the Grid?
Severin Borenstein at the Energy Institute at Haas and Ryan Kellogg at the University of Chicago question whether carbon pricing is the best way to decarbonise the electricity grid. The authors did an empirical analysis of all of the fossil plants in the US. It shows that a CES (clean electricity standard) or zero-emissions subsidies would close down fossil plants in almost the same order as a carbon tax. So using alternative policy tools can … [Read more...]
Donât cap gas prices for consumers. It wonât reduce demand. Instead, subsidies must reward cuts in gas use
European nations are considering capping the price of gas that consumers pay, a subsidy that governments will pay for, to ensure households donât freeze this winter. Daniel Gros at CEPS warns that this strategy will remove the incentive for consumers to cut their gas use, keeping international market prices high. Instead, governments should incentivise a reduction in gas use. Gros has modelled two strategies. The first is to pay households for … [Read more...]
The light bulb transition: when standards and subsidies promote sub-optimal technologies
This article is for those who want to understand the importance of timing: when is the right time to impose new standards and start/stop subsidies, to optimise the pathway to maximum efficiency? The light bulb transition of the last two decades is one of the successes of energy efficiency: from the old incandescents (15 lumens/watt) to halogen incandescents and CFLs, and then, finally, to LEDs (80 lumens/watt and prices falling 90% in ten years). … [Read more...]
Do e-bike subsidies lift sales, change habits and cut emissions?
What happened when Sweden introduced a 25% rebate on the cost of an e-bike for 12 months over 2017-18? Lucas Davis at the Haas School of Business reviews a study that digs into the consequences. Sales increased by 70%. E-bike prices remained steady, so the sellers didnât simply raise prices to eat up the rebate. The study estimates that although a third of those sales would have âhappened anywayâ (i.e. no additionality) the remaining two-thirds … [Read more...]
Electricity markets with high shares of Wind and Solar will need Nuclear
When electricity markets have high shares of wind and solar â the goal of many regions around the world â is it more efficient to build a nuclear power plant instead of investing further in more renewable capacity? The answer is yes, according to a study by Machiel Mulder, Xinyu Li and Arjen Veenstra at the University of Groningen. In essence, itâs because nuclear benefits from the high (scarcity) prices when thereâs little wind or sunshine. Here … [Read more...]
Worldâs biggest Carbon Capture project: Shute Creekâs âsell or ventâ business model isnât working
ExxonMobilâs Shute Creek CCUS facility is the worldâs largest carbon capture project. But since its launch in the 1980s half of that CO2 has been vented into the atmosphere, with most of the rest sold for pumping it underground to push out more oil from depleted wells (called Enhanced Oil Recovery). Only 3% has been sequestered underground, explain Bruce Robertson and Milad Mousavian at IEEFA, following their study based on publicly available … [Read more...]
What is Energy Security? And what it isnât
What is energy security? Thatâs what Maximilian Auffhammer at the Energy Institute at Haas asks and tries to answer, and he starts by saying what it is not and what solutions should not be used. Not importing wonât help because prices are global. âEnergy securityâ canât be taxed as an externality for much the same reason. Subsidising high prices for consumers decreases the value of energy efficiency investments. Instead, Auffhammer says the … [Read more...]
Germany: can 100% renewable power reduce energy costs within the decade?
A bold report is presented by Thure Traber, Hans-Josef Fell and Sophie Marquitan at Energy Watch Group. It says that a 100% renewable power system for Germany can undercut fossil power within this decade. The authors look at the full cost of fossil power, including subsidies. Importantly, they explain how unit costs will rise further, as demand declines, due to the decreasing utilisation of its expensive infrastructure. Meanwhile, total system … [Read more...]
Clean transport in Europe: key trends to watch out for
T&Eâs quarterly trends series gives a snapshot of the key developments that will define the future of clean transport in Europe. And what Europe does â given it wants to lead this field â should influence what happens worldwide. T&Eâs Thomas Earl brings attention to four issues. First, proven progress in this major sector makes it a contender for a significant role in Europeâs new industrial strategy. It ranges from battery and … [Read more...]
End Fossil Fuel subsidies by shifting them to poorer households
In May, the environment ministers of the G7 agreed to end fossil fuel subsidies within this decade. Around $650 bn/year is spent worldwide on subsidising all energy sources, with the majority ($450bn) going to fossil fuels despite the climate crisis. But simply removing the subsidies has proven difficult. They keep energy costs low for consumers. Itâs why public protest resisted the change in Ecuador and France in 2019. And developing nations … [Read more...]
Hydrogen: can gas, electricity and industrial majors agree on the next steps?
Hereâs our written summary of our panel debate held on 16th June âHydrogen: Designing the Net Zero Gas Systemâ. With representatives from BASF, SNAM and ELIA to cover consumption, gas and electricity, there were plenty of differences of opinion. For example, with no end in sight for demand for green electricity for the grid, is it efficient to use some of it for hydrogen? Will subsidies for hydrogen skew markets away from industrial … [Read more...]
Outlook USA: even with battery costs, Wind and Solar can undercut Coal and Gas by 2023-24
IEEFA has published its U.S. Power Sector Outlook 2021. Its authors, Dennis Wamsted, Seth Feaster and David Schlissel summarise and explain the projections. They say that coal and gas are set to become the biggest losers as renewable generation climbs quickly. The future for wind and solar â coupled with storage to address intermittency - is looking very good. They present estimates from NextEra (the largest renewable energy developer in the … [Read more...]
Germanyâs plans to be a Hydrogen leader: producer, consumer, solutions provider
Germany is getting in early on the proposed hydrogen economy as a producer, consumer and with intentions to be the leading international supplier of hydrogen technologies. Simon Göss at Energy Brainpool runs through the main drivers for hydrogen before summarising the German strategy. The German 2030 target is to have electrolyser capacity of 5GW installed to produce 14TWh of green hydrogen, providing 15% of the hydrogen consumed in Germany by … [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 itâs difficult to know whatâs actually going on. Is the data wrong (they donât think so), or are EVs only being bought by drivers who don't use a car much? If so, the … [Read more...]
