Wind Turbines: how dependent is the EU on China?

by

Joseph Webster at the Atlantic Council’s Global Energy Center takes stock of the European wind sector’s dependence on China. Nobody wants geopolitics and a worsening relationship with Beijing to disrupt positive cooperation in the urgent energy transition. The news is mostly good: the dependence is low because the international trade in turbines is constrained by weight-to-value ratios, transportation costs, and local content requirements. In … [Read more...]

‘Green Deal Industrial Plan’ explainer: 40%+ of the top low-carbon technologies must be made in the EU by 2030

by and

The EC’s new series of proposed targets and reforms, contained in its Green Deal Industrial Plan, aim to ensure that at least 40% of the EU’s low-carbon technologies will be made within its borders by 2030. The eight “strategic net-zero technologies” are: Solar (power and thermal); Onshore and offshore wind; Batteries and energy storage; Heat pumps and geothermal; Electrolysers and fuel cells; Sustainable biogas/biomethane; CCS; Grid … [Read more...]

U.S. IRA: what can Europe do to stop its firms relocating to America?

by and

There’s been plenty of news about Europe’s worries over the U.S. Inflation Reduction Act, launched in August last year. It will deliver a broad range of subsidies, incentives and domestic manufacturing requirements that promote green technological innovation in the U.S., encompassing wind, solar, hydrogen and more, backed with a budget of $369bn. It is also designed to encourage the purchase of U.S.-made green energy products like EVs. Europe is … [Read more...]

Fulfilling U.S. wind and solar ambitions will use under 1% of its land (that’s less than the fossil fuel footprint)

by

Meeting the U.S.’s wind and solar ambitions in full would take up less than 1% of its land, less than the fossil fuel industry’s current footprint. Steve Clemmer at UCS goes into the details of NREL’s comprehensive study of land use for wind and solar. Of particular interest is the observation that setting a high bar for “responsible siting” of wind and solar projects - avoiding the use of sensitive, protected, urban areas, difficult terrain or … [Read more...]

ReDREAM: Horizon-backed project gives consumers control of local renewables, prices and demand

by

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...]

How to protect marine mammals from the coming roll-out of Offshore Wind

by

The EU’s target for offshore wind is an installed capacity of at least 60 GW by 2030, and 300 GW by 2050. It will use the vast potential of the five EU sea basins, in particular the North Sea and the Baltic Sea. But growing awareness and concern over their impact on the marine ecosystem will require new methods of protecting sea life from the consequences. Isla Graham at the University of Aberdeen describes the work of her team on measuring … [Read more...]

Wind and Solar generated record 20% of EU electricity in 2022. More than gas, nuclear, hydro, coal

by

Now 2022 is over, the figures are in for all the main electricity generation types. For the first time ever, wind and solar delivered more electricity in 2022 than gas, nuclear, hydro or coal. In total, that’s a record one-fifth of the EU’s electricity last year. We can thank the “triple crisis” of Russian gas cuts, the 500-year record drought’s effect on hydro, and the unexpected French nuclear shutdowns for the renewed drive for wind and solar. … [Read more...]

Wind (and Solar) need their own Financial Transmission Rights to hedge their unique congestion risks

by

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...]

What’s stopping even bigger Wind Turbines? Blade speed and flexing? More likely manufacturing and installation capacity

by

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 £50/MWh (€56/$61). But how big … [Read more...]

How to tax renewable energy firms for windfall profits from high wholesale electricity prices

by

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

by

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...]

Russia, fossil prices, energy security will boost Renewables to 38% of global power mix by 2027, says IEA

by

The IEA has raised its 2027 forecasts for total renewables additions in its main scenario to 2,383GW – around the total power capacity of China. That’s a 28% increase on the previous estimate and up 76% from two years ago, explains Josh Gabbatiss at Carbon Brief who summarises the IEA’s latest forecasts. Globally, solar power will overtake gas by installed capacity in 2026 and coal in 2027. There are two main drivers for this acceleration. High … [Read more...]

Health benefits of Wind Power: first replace the most polluting fossil plants, not the most expensive

by

It makes economic sense, when intermittent wind (or solar) generation rises, to turn down the most expensive fossil plants. Or does it? Join the dots to health costs and it may make more economic sense to turn down the most polluting plants first. Jennifer Chu at MIT describes research there that creates models and scenarios to interrogate that theory. Using hourly generation records, pollution and health cost data from across the U.S. they found … [Read more...]

Comparing the efficiency and progress of the 5 leading Solar PV cell technologies

by and

NREL’s “Best Research-Cell Efficiency Chart” allows researchers to easily compare the performance of specific PV technologies, stretching back 50 years. It’s regularly updated and is free to use, explains Wayne Hicks and Harrison Dreves at NREL. A new “interactive” version is now available. The focus is on crystalline silicon cells, single-junction gallium arsenide cells, multijunction cells, thin films, and emerging PV. For example, you can … [Read more...]

EU Energy Outlook to 2060: how will power prices and revenues develop for wind, solar, gas, hydrogen + more

by and

Alex Schmitt and Huangluolun Zhou at Energy Brainpool present a summary of their “EU Energy Outlook 2060”. Its scenarios map out how the European (EU 27, UK, Switzerland and Norway) energy system will change dramatically in the coming decades. Current geopolitical tensions are added to climate mitigation and an outdated power plant fleet as the main drivers of change at the EU and national levels. The in-depth modelling is trying to answer the … [Read more...]
