Decarbonising heating is a major challenge for any country. Germany’s Building Energy Act (GEG) means that from 2024 every newly installed heating system, in new or existing buildings, must operate with a minimum of 65% renewable energy. Concerns over the costs to customers (installing new and expensive systems, or paying a penalty for fossil heating) has led to intense debates, hence the new law includes a range of subsidies, bonuses, discounted … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes “congestion” at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. That’s certainly the case in the U.S. now. One answer is “hybridisation” where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
Russia’s war has exposed France and Germany’s energy policy differences. Can it also bring them together?
France and Germany combined account for 45% of EU GDP and 40% of energy consumption. No wonder they are the most influential EU members. But the Russia-induced energy crisis has forced both Paris and Berlin to expose and admit the differences in their national energy strategies, and that has made a search for a unified voice for Europe’s ambitious climate targets much harder to achieve, explain Camille Lafrance and Benjamin Wehrmann at CLEW. … [Read more...]
Clean Energy Innovation: investment continued to rise despite a turbulent 2022
In a turbulent year, financially and geopolitically, investment in energy innovation still rose. Public spending on energy R&D grew by 10% in 2022 (estimated at $44bn), with 80% devoted to clean energy. Listed energy-related companies saw a similar rise. And early-stage venture capital investment reached a new high of $6.7bn. But risks remain, explains Simon Bennett at the IEA who summarises the innovation chapter in their latest “World … [Read more...]
Electric Utilities: ESG investors should invest in, not avoid, the high-carbon emitters
Environmental, social, and governance (ESG) ratings point climate-conscious investors away from companies that are not decarbonising fast enough (or at all!). But surely they should be doing the exact opposite when it comes to climate-critical sectors like electric utilities, explain Tricia Holland, Ryan Foelske, Ella Warshauer, Jon Rea, Sarah LaMonaca and Uday Varadarajan at RMI. Of course, that presents a new challenge. The investor first needs … [Read more...]
Germany closes its last 3 nuclear reactors. Understanding the reasons why
Germany has a long history of being resistant to all things nuclear. No new commercial reactors have been built since 1989. By 2023, nuclear made up only 6% of its power mix. To meet its decarbonisation goals, the government is confident of its target to reach an 80% renewables share in electricity demand by 2030 without nuclear. Hence the shut-down of its last three reactors over the weekend. Yet nuclear supporters say that leaving the last six … [Read more...]
Renewables “cost of capital” in Europe lower than oil, gas, coal. What the U.S. and China can learn
The ultimate price of anything is highly dependent on the cost of capital needed to put it in place. That cost reflects the risks financial markets perceive. And policy certainty reduces risk. Gireesh Shrimali, Christian Wilson and Xiaoyan Zhou at Oxford University, writing for WEF, summarise their global study which shows the cost of capital for different energy technologies, and therefore which ones will trend upwards and dominate. They cover … [Read more...]
ReDREAM: Horizon-backed project gives consumers control of local renewables, prices and demand
The ReDREAM project, funded by EU Horizon 2020, wants to put consumers at the centre of the energy market. As Steve Gillman explains, people and businesses can shape their supply and demand by owning local renewable generation and combining that with smart systems that give visibility of prices and generation to enable control of demand, right down to the level of heat pumps, washing machines, hot water systems and EVs. A 30-household pilot is … [Read more...]
Electricity Market Design: how can reforms accelerate the transition and help cut energy prices?
*** REGISTER NOW *** for our online panel discussion on Friday 24th March 09:30-10:45 CET, “Electricity Market Design: how can reforms accelerate the transition and help cut energy prices?” Our panellists are Catharina Sikow-Magny, Director, DG ENER; Wanda Buk, Vice-President for Regulatory Affairs, PGE; Leonardo Meeus, Director of the Florence School of Regulation; JĂ©rĂ´me Le Page, Director for European Electricity Markets, EFET; Michaela … [Read more...]
Wind (and Solar) need their own Financial Transmission Rights to hedge their unique congestion risks
Financial Transmission Rights (FTRs) help generators and load-serving entities hedge congestion-related risk. Transmission congestion causes a divergence between wholesale power prices where it is generated and the trading hubs where it is delivered and sold. Because the congestion, and therefore the risk, varies over time it is particularly important to variable renewables. That uncertainty increases investor risk which potentially slows … [Read more...]
Utah: 140MW Geothermal bid can beat the cost and performance of the proposed Nuclear SMR
The U.S. state of Utah is processing an agreement for a new Small Modular Reactor (SMR) to provide baseline and dispatchable power. The SMR bid quotes a price of $89/MWh. But cost overruns will tie the state’s consumers to whatever high prices entail, says Dennis Wamsted at IEEFA. Now a geothermal bid from NV Energy has been presented that offers the same capacity at around $70/MWh. Wamsted explains why the 140MW geothermal project would meet … [Read more...]
What’s stopping even bigger Wind Turbines? Blade speed and flexing? More likely manufacturing and installation capacity
Bigger wind turbines make cheaper energy. The sector’s unexpectedly rapid successes in designing and building bigger and bigger turbines has been one of the major success stories of the clean energy sector. In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electric’s Haliade X turbines stands 260m high from sea level and can generate 13MW at under ÂŁ50/MWh (€56/$61). But how big … [Read more...]
Making Hydrogen will consume 2% of total global renewable capacity growth by 2027
25 countries plus the EU have announced big ambitions for renewable hydrogen production. But how much renewable energy will be needed to make the H2 over the next five years? Nations are not keen to expend new clean energy generation on (expensive today) hydrogen production when their grids are still not emissions-free. According to the IEA, for 2022-2027, their main case forecasts around 50GW of renewable capacity will be dedicated to hydrogen … [Read more...]
How to tax renewable energy firms for windfall profits from high wholesale electricity prices
Should windfall taxes be imposed on renewable energy firms that have benefitted from the current high electricity prices caused by the increases in oil, gas and coal prices triggered by Russia’s invasion of Ukraine? If so, how, and how much? The IEA has conducted a study of the EU to try to uncover who has (and hasn’t) made extraordinary profits, and how much. Up front they say this is difficult to do as the majority of installed renewable … [Read more...]
Corporate targets are forcing suppliers to cut emissions or relocate to clean energy nations
Emissions targets being imposed by corporates in the U.S. and Europe are forcing manufacturers in other parts of the world to decarbonise, writes Kwangyin Liu at Clean Energy Wire. Here, she looks at how Taiwan’s TSMC – the world’s third largest chip manufacturer – is having to set up factories in Arizona (U.S.) and Kumamoto (Japan) where emissions are lower and thus to comply with requirements set by customers like Apple, Google and Microsoft. … [Read more...]
