The rapid pace of change in the energy sector is a positive sign for the transition. But the disruption it causes creates another big problem. It makes it harder to predict what will happen next. That makes strategies and pathways harder to design, and increases the risk of stranded assets. To try to come to grips with that future, Sean Ratka, Paul Durrant and Francisco Boshell summarise the findings of IRENA's 4-day “Innovation Week” held last … [Read more...]
Renewables shares outperformed fossil fuels over 10 years. Have investors noticed?
Shares in listed renewables firms are outperforming their fossil fuel equivalents, both in terms of returns and volatility. But although investment is rising, they’re still not getting enough to meet our 2050 targets, says the IEA. Why? In this article summarising the first of a series of reports they look at the 5 and 10 year record of the two verticals. In all the three territories analysed – the U.S., the U.K., and Germany/France - renewables … [Read more...]
Europe’s 55% emissions cut by 2030: proposed target means even faster coal exit
The EC is proposing a target emissions reduction of 55% by 2030 compared to 1990 levels, instead of the previously agreed 40% (which the EU is on course to surpass). The main tool for achieving it will be the EU Emissions Trading System (ETS). Prices for allowances will rise, making coal increasingly uncompetitive. Sören Amelang, Kerstine Appunn and Julian Wettengel at CLEW talked to a number of experts who say the new target implies a near total … [Read more...]
Sweden’s new “prosumers”: electricity generation at the city, village and residential level
54% of Sweden’s power already comes from renewables – the target is 100% by 2040 - and more and more is being generated locally on a small distributed scale, says Harry Kretchmer writing for the World Economic Forum. ‘District Heating’ plants are today using excess heat to warm over 75% of Swedish homes. Residential generation is happening too, creating “prosumers” who both produce and consume. In Ludivika, 1970s flats have been retrofitted with … [Read more...]
No more “offsetting”: Google commits to 24/7 locally sourced carbon-free electricity by 2030
By “offsetting” fossil electricity consumed at one data centre through buying green power from somewhere else, Google has been 100% renewable since 2017. But offsetting always has its flaws. In this case, 40% of Google’s actual power still comes from fossil fuels. Google’s new plan, to be 100% green 24/7 straight off the local grid, is designed to solve that. It will also send market signals to increase clean capacity locally, not just where you … [Read more...]
BP Outlook 2020: “peak oil” has already happened
BP’s latest Outlook predicts – for the first time - that oil saw its peak in 2019. In each of BP’s Outlooks, published annually since 2011, they have revised their predictions for the global energy landscape to 2050 as new data comes in. The growth of clean energy and the changing shape of climate policies have seen each successive forecast increase the share of renewables at the expense of fossil fuels. This year even gas has seen its prospects … [Read more...]
We need Behaviour Change and “Life Efficiency”, because efficiency gains and clean energy will never be enough
Behaviour change – reducing emissions by changing how we live our lives - should be part of every government and think tank’s sustainable scenario, explains Schalk Cloete. That’s because impressive advances in energy efficiency and clean energy won’t be enough to contain the emissions of a world continuing with the essential task of lifting billions of people out of poverty. But this should not be seen as a problem, says Cloete, because behaviour … [Read more...]
Green Ammonia Market: a New Era for Energy and Power Industry
Green ammonia uses renewable energy instead of natural gas or coal for producing hydrogen; hence, is an effective way to reduce greenhouse emissions. The electrochemical Haber-Bosch process produces ammonia without any greenhouse emissions. Green ammonia refers to ammonia, which has been produced through a process that is 100% renewable and carbon-free. Reducing the carbon dioxide emissions during the production process is essential to achieve … [Read more...]
Little progress decarbonising Industry. Renewables can be the answer
The decarbonisation of heavy industry is making little progress. There are two main reasons. Firstly, there are no easy technology wins. Efficiency and carbon capture have been the favoured options. But efficiency gains have their limits, and carbon capture is still proving very expensive. Secondly, governments don’t want their home industries to lose competitiveness incurring costs reducing emissions. Dolf Gielen and Paul Durrant at IRENA say a … [Read more...]
BP’s world energy review: 2019 saw clean electricity match coal
Simon Evans at Carbon Brief summarises BP’s 69th edition of its influential annual statistical review of world energy, looking at 2019. Overall, total energy demand rose, though slower than usual. Renewables were the largest source of new energy, but were closely followed by oil and gas. Coal use dropped again, the fourth drop in six years, thanks to historic declines in the EU and the US. But continued growth in SE Asia, China and India leaves … [Read more...]
The PAC Scenario: net-zero by 2040 to meet Europe’s Paris goals
The EU is not on track to meet its Paris Agreement obligations on emissions and limiting the global temperature rise to 1.5°C. CAN Europe and the European Environmental Bureau (EEB) present their Paris Agreement Compatible (PAC) scenario, designed to do just that. It’s been created through the careful analysis of contributions from more than 150 stakeholders including NGOs, scientists, industry and grid operators. Jörg Mühlenhoff at CAN Europe … [Read more...]
The nexus between data centres, efficiency and renewables: a role model for the energy transition
How much will electricity consumption from data centres grow from today’s 1% of the global total? 40-fold by 2030? Or a more manageable 5-fold? Or less? Sean Ratka and Francisco Boshell at IRENA try to answer this question by looking at the innovations being made by the tech industry to drive down power costs and emissions. The evidence is promising. Though data centre computing output jumped 6- fold between 2010 and 2018, their energy … [Read more...]
Will Member States support the EC’s green recovery plan?
The EC’s “Next Generation EU” plan for a joint loan of €750bn is a major breakthrough as it accepts the need for the member states to share a large debt burden to revive the EU economy. It will be in addition to the European budget under discussion before the pandemic crisis. The other breakthrough is that green policies – climate neutrality, biodiversity, “food-to-fork” - are central, explains Nicolas Berghmans at IDDRI. He summarises the plan, … [Read more...]
Grid-scale Solar PV storage can use re-purposed old EV batteries
Once an EV battery has declined to 80% of its original capacity it is considered too weak for continued vehicle use. Recycling the battery – at that point - to make another one is expensive. MIT’s David Chandler describes how researchers there have run experiments and models to show that old EV batteries can instead be packed together and used as backup storage for grid-scale solar PV installations. It’s cheaper than building new Li-ion battery … [Read more...]
Clean Energy threatened by lockdown of critical minerals supply
Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric transport and grid storage are now the largest consumers of lithium and cobalt. Examples of rising consumption abound for other … [Read more...]
