When wind turbine blades are decommissioned they are usually scrapped and thrown into landfill because they cannot be recycled. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades. As wind installations increase so will that number. It's because most blades are constructed from epoxy or other thermoset resins. So National Renewable Energy Laboratory (NREL) researchers are using a thermoplastic resin, … [Read more...]
Latest data shows lifetime emissions of EVs lower than petrol, diesel
Critics of the rapid roll out of electric vehicles correctly say that their factory door emissions (i.e. CO2 emitted during manufacture) are higher than those for standard petrol and diesel cars. Then you have to add the emissions of the local grid (how renewable is it?!) that’s charging your EV. But the numbers behind those calculations are always changing. Eoin Bannon at Transport and Environment describes the findings of their new tool that … [Read more...]
Investing for tomorrow, because Energy subsidies will decline 25% by 2050 – analysis
IRENA has modelled energy subsidies to 2030 and 2050 for their pathway to meet the Paris targets. Here, Michael Taylor summarises their findings. Firstly, they estimate today’s global direct energy sector subsidies to be $634bn/year (2017 figures). The vast majority, $447bn, went to fossil fuels. (By the way, he points out that none of these figures include the externality costs - pollution, healthcare, environment - which equate to trillions and … [Read more...]
IEA projections 2020: energy demand plunges but Renewables still grow at Gas, Coal’s expense
The IEA has made its projections for the impact of the pandemic lockdown on energy demand in 2020 (they say it’s too early for them to assess anything more long term), and its implications for the different generation types. This article summarises their special Global Energy Review 2020, published at the end of last week. It assumes that lockdowns are eased this year and growth gradually returns. With that, global energy demand will fall 6% in … [Read more...]
DSOs can use digitalisation to empower all grid stakeholders
Distribution System Operators (DSOs) are in charge of operating, maintaining and developing the distribution network to ensure that electricity is delivered to end-users in a secure, reliable and efficient manner. Harry Taylor, Chris Collins and Erik Rakhou at Baringa Partners spell out what DSOs need to do to take full advantage of digitalisation technologies and processes to make them fit for a rapidly transforming energy system. A growing … [Read more...]
IRENA’s Global Renewables Outlook and how Europe can lead the way
If the coronavirus slump has knocked everything off track IRENA’s first ever Global Renewables Outlook is a timely reminder of what that track should look like. It can help policymakers design stimuli packages that will get us back onto it, and even accelerate the transition. IRENA’s Gayathri Prakash, Nicholas Wagner and Ricardo Gorini run through the comprehensive report’s main recommendations. Annual investment, shares and GW targets to 2030 … [Read more...]
U.S.: Counting Renewables jobs and projects under threat, what can be done and why
All sectors across all economies are trying to add up their potential job losses and projects in jeopardy, then telling their governments to prioritise them for support. Mike Jacobs at the Union of Concerned Scientists looks at renewables in the U.S. He quotes news reports that over 100,000 workers in this fast-growing industry filed for unemployment in March 2020. On top of that, the already planned expiry and phase-down of certain targeted … [Read more...]
Regulatory challenges to foster cross-border trade in electricity systems with increasing shares of renewables
The share of renewable generation in Europe’s power system is rising fast, but interconnection is not keeping up. Join us on May 19, 2020 to discuss this and related issues. More wind and solar makes the supply of electricity much more dependent on the weather. Nobody wants to build capacity only to switch it off when there’s too much heading onto the local grid. This could put an extra strain on delivering the Green Deal. One solution is to … [Read more...]
IEA: Three ways governments can keep Renewables growth on track
Before the coronavirus pandemic, 2020 was set to be another record year for renewables installations. That is now looking very unlikely. Heymi Bahar at the IEA identifies three main challenges facing the growth of renewables due to the global economic consequences of the pandemic: Supply chain disruptions, anywhere, will surely lead to delays in completing projects everywhere; Compounding those delays, major renewables incentives expire at the … [Read more...]
Will China build more Coal to stimulate the economy?
Could China ramp up coal generation – of the order of hundreds of GW by 2030 - as part of its efforts to stimulate its economy and recover from the coronavirus slump? The thinking is that building a coal plant converts faster into economic growth than the equivalent spent on renewables. In the previous decade, building coal plants was an effective part of China’s economic growth plan that secured its place as the world’s second largest economy. … [Read more...]
The value of PPAs during economic turmoil
IEEFA says that the global economic slump being caused by the coronavirus pandemic can show how Power Purchase Agreements (PPAs) protect you against uncertainty. PPAs are long term contracts and prices agreed with energy suppliers. Renewable energy PPAs are one of the best ways big customers in the private sector can support the transition, guaranteeing suppliers income over the long term. Particularly for electricity-intensive sectors, renewable … [Read more...]
What if Germany wasn’t shutting down Nuclear? Modelling Coal, Gas, Renewables, emissions, prices
Germany plans to shut down its entire nuclear fleet by 2022. Right now, of the original 17, only 7 are still running. The Fukushima nuclear accident in Japan of 2011 was the trigger for Germany’s abandonment of emissions-free nuclear as part of its clean energy goals. Maximilian Auffhammer at the Energy Institute at Haas reviews a paper by his colleagues that has modelled the whole-system effects of the shutdowns, then compared the results with a … [Read more...]
Poland’s PGE: profits from Renewables can replace declining Coal’s
Poland’s PGE is one of Europe’s most fossil fuel intensive energy firms. Coal makes up around 90% of its electricity generation. It’s been investing around PLN 28bn ($7.2bn, €7bn) to build three new coal power plant units, acquire the Polish coal assets of France’s EDF, and upgrade its existing fleet to meet air quality standards. But a new and detailed report from IEEFA warns that the profitability of these investments will decline in the 2020s … [Read more...]
60 years on, OPEC should take control again, cut supply, raise prices to fund its Transition
OPEC is often seen as no friend of the Transition. But Greg Muttitt points out that, although it did take an anti-climate stance in the 1990s, by the 2000s it had stepped back from climate negotiations, while some OPEC members became supporters. Muttitt says that, celebrating its 60th anniversary, it’s time for OPEC to remember its roots and organise its members to take control of their own destiny in the face of the inevitable rise of clean … [Read more...]
Tech-Neutral Auctions for Renewable Energy: are poorly defined rules creating loopholes?
The EC’s Environmental and Energy State Aid Guidelines 2014-2020 (EEAG) require Member States to implement technology-neutral auctions as part of their renewable energy support schemes. However, the reality looks quite different, write Bastian Lotz and Silvana Tiedemann from Navigant (a Guidehouse company), Lars Jerrentrup of Aurora Energy Research, and Lion Hirth from Neon. Most Member States continue to use technology-specific auctions, using … [Read more...]
