We should not be surprised to see a growing number of 100% renewables roadmaps, with target dates in the 2030s, from nations as the transition gains pace. This study, “On the Road to 100 Percent Renewables” led by The Union of Concerned Scientists (UCS), details how the 24 states that make up the members of the U.S. Climate Alliance (USCA) can meet all of their electricity needs with renewable energy by 2035. Paula Garcia at UCS summarises the … [Read more...]
Europe must simultaneously replace Russia’s fossil exports and accelerate its clean energy deployment
The Ukraine crisis has had an immediate impact on Europe’s strategy for energy supply security. And this week’s sudden halting of gas supplies by Russia to Poland and Bulgaria only emphasises the urgency. Dolf Gielen, Ricardo Gorini, Luis Janeiro and Seán Collins at IRENA look at the best options, basing their findings on their latest “World Energy Transitions Outlook”, published in March, that lays out a routemap for the next eight years for … [Read more...]
Post-war Ukraine needs energy independence, decarbonisation and EU cooperation
Energy independence is a choice for some countries. For Ukraine it is a life-or-death necessity, says Andriy Konechenkov, VP of the World Wind Energy Association and Chairman of the Ukrainian Wind Energy Association, in this op-ed. The Russian invasion has exposed the vulnerability of Ukraine’s current energy system. Many of its fossil-fuelled power plants are near the Russian border, exposing them to disruption by the invading neighbour. The … [Read more...]
Q&A: How fast can renewables deliver on Germany’s new energy independence goals?
How quickly can Germany reduce its dependence on fossil fuels? Benjamin Wehrmann at Clean Energy Wire asks six practical questions that must be answered, then gathers the expert answers. What are the current expansion goals for wind, solar and other renewables? Following Russia’s invasion of Ukraine, will the new emergency plans bring an end to Russian imports as well as reach climate targets? Are renewable power companies ready to deliver a fast … [Read more...]
U.S. EIA Annual Energy Outlook 2022 reveals no reduction in emissions to 2050
The U.S. Department of Energy’s Energy Information Administration (EIA) has released its influential 2022 “Annual Energy Outlook” (AEO2022) which projects the electricity mix over the next 30 years. (The modelling takes policies and global conditions as they were in November 2021, so the current Russia-Ukraine crisis is not accounted for, nor any future unforeseeable shocks, and assumes no new policies to 2050). Sandra Sattler at the Union of … [Read more...]
“Floato-voltaics”: floating solar farms on existing municipal water reservoirs
The municipality of Cohoes, population 17,000, in New York State, is building a floating solar farm on its 10-acre water reservoir. It should power all the city-owned buildings and streetlights, save $500,000/year in electricity costs and still leave 40% of the generated electricity remaining for other civic use. It will cost $6m. It will be a first for a U.S. city, explains Connor O'Neil at NREL. The case for city “floato-voltaics” is so … [Read more...]
What can replace Russian gas: modelling Germany’s options on renewables, coal, nuclear, LNG, lowering thermostats
A sudden cut in Russian gas imports means Germany will have to cope with the loss of TWhs. How? Tobias Federico at Energy Brainpool wants decision-makers to get the facts straight. He uses modelling tools to answer this question that is causing fierce debate. The first thing to note is that the loss of gas TWhs (of the order of 100TWh) will be most felt in the provision of heat over winter. Heating systems mostly depends on gas, so intermittent … [Read more...]
Russia-Ukraine and Europe’s energy strategy: a snapshot of a fast-moving crisis
Every day brings news of how Europe’s energy policy is reacting to Russia’s invasion of Ukraine. It’s a big topic and fast moving. Helen Farrell gives a summary of the situation so far. She lists some of the major U-turns at both EU and national levels, the IEA’s ten-point recommendations, the feasibility and repercussions of cutting Russian fossil imports, the prospects for clean energy (solar, wind, nuclear, storage) and our net zero targets. … [Read more...]
What is Energy Security? And what it isn’t
What is energy security? That’s 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 won’t help because prices are global. “Energy security” can’t 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...]
Russia-Ukraine crisis: reforming the EU ETS is a matter of energy security, says PGE
European leaders are now rushing to make decisions on how to drastically cut dependence on Russian fossil energy imports. Russia’s invasion of Ukraine has exposed Europe’s energy security vulnerabilities like nothing else could have. It also means Europe’s clean energy transition will need an overhaul, and a newly designed optimal pathway created, and fast. Wojciech DÄ…browski, President at PGE Polska Grupa Energetyczna, explains that it must also … [Read more...]
Biomethane for decarbonising transport: the Swedish example
Biomethane has a critical role to play in the decarbonisation of transport, particularly long-distance trucks and ships, where electrification is more difficult and expensive. Angela Sainz Arnau at the European Biogas Association explains that biomethane represents one of the lowest greenhouse gas intensive pathways when the whole emissions lifecycle is measured. However, when nations implement bans on internal combustion engines to cut the use … [Read more...]
Community Biomass: for energy independence, stable prices and local control
Energy independence is now at the top of the EU’s agenda. Almost all Europe’s biomass is already locally produced, contributing around 60% of the EU’s renewable energy. Marine Perrio at IEECP makes the case for promoting biomass prosumer projects. She points at regions dependent on biomass that have reported stable energy prices in the midst of the drastic increases in gas, oil and coal prices. Biomass uses organic feedstock from agriculture, … [Read more...]
Smart households in a high Renewables world: flexible, efficient, cheaper
Smart controls can enable household heating and EVs to interact flexibly with increasingly decentralised electricity generation. As renewables continue to be added to the energy mix, it will increase efficiency, reduce load, and save money. Marco Reiser and Karoline Steinbacher at Guidehouse summarise the challenges and opportunities, before looking at the SINTEG pilot in Germany. The main hurdles are technological (standardisation, interfaces, … [Read more...]
Reducing Europe’s dependence on Russian Oil and Gas: immediate, short and long term strategy
Atlantic Council Global Energy Center experts and associates offer their template for drastically reducing Europe’s dependence on Russian oil and gas. It’s broken down into immediate, short (one to three years) and long term (beyond three years) actions. It’s wide-ranging and comprehensive. Some actions are already in play, including maximising gas storage, ready for next winter. Some are the ramping up of existing plans (clean energy, … [Read more...]
Germany’s electrification ambitions: TSOs scenario for 91% Renewables by 2045
The German TSOs submitted in January scenarios for their grid to 2037, making projections for increasing electrification. In addition, and for the first time, they included an ambitious and long term scenario to 2045. By pure chance, the Russian invasion of Ukraine and Germany’s response – to consider a reduction in its serious dependence on Russian energy imports – should make eyes turn sharply towards that 2045 scenario. Simon Göss at cr.hub, … [Read more...]
