Geothermal is not just for generating energy. It can be used for storage and extracting minerals too. Kelly MacGregor at NREL summarises the research into taking geothermal to the next level and making it a solution to multiple challenges. Depending on how far down you dig, geothermal is available for running utility-scale power plants as well as heating and cooling individual districts, buildings and houses. And new techniques are being … [Read more...]
What is the future of Woody Biomass in the EU energy mix?
Simon Göss provides an overview of the main issues surrounding the intense policy debate over the future of biomass in the EU. The current proposals of the EU parliament still allow certain woody biomass to be used for all kinds of energy purposes but limits the share that primary woody biomass can contribute towards renewable energy targets. Included in the proposals is a new definition of primary woody biomass, and a phase-out of financial … [Read more...]
Big Consultancies are now advising on climate change. Will it conflict with their business-as-usual work?
The worldâs top management consultancies - like BCG, Accenture, PwC, EY, McKinseys - who for decades have advised the biggest polluters, are now rushing into the business of helping companies cut emissions to become more sustainable, explains Emma Thomasson at Clean Energy Wire. The necessary expertise is in very short supply, so they are retraining staff, poaching environmental experts, and buying up smaller specialist firms. BCG is even running … [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 Taiwanâs TSMC â the worldâs third largest chip manufacturer â 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...]
Wellbeing peaks at just 75GJ per capita: a reachable target for poorer nations to rise to (and rich ones to fall to)
Energy consumption is strongly linked to health and wellbeing, in particular life expectancy, infant mortality, happiness, food supply, access to basic sanitation services and access to electricity. But as Josie Garthwaite at Stanford University explains, new research is saying that those improvements cease above a certain number of gigajoules per person per year. Knowing that number will make understanding and setting targets much easier. For a … [Read more...]
Event summary: âUnlocking the potential of Bioenergyâ
Sara Stefanini provides a written summary of our panel discussion held on Thursday March 17th 2022. Itâs a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights (potential for bioenergy, hard-to-abate sectors, sustainability, policy needs). Those highlights include the need to scale bioenergy up from around 50 EJ today to 150 EJ by 2050; the importance of carbon … [Read more...]
Wind and Solar expansion is a threat to biodiversity. But by how much?
Wind and solar take up space, so a massive expansion will have an effect on biodiversity. But how much? Sebastian Dunnett at Hammersmith and Fulham Council in London, writing for Carbon Brief, summarises his co-authored paper that takes the latest data on wind and solar and its multiple impacts (a few are good, surprisingly) on the environment. The conclusion is that the consequences of land overlap need not be as severe as feared, provided … [Read more...]
EU Taxonomy: why nations are backing Nuclear and Gas
The heated debates over the potential inclusion of nuclear power and natural gas in the EU taxonomy has again exposed the different interests of EU nations. Simon Göss at cr.hub, writing for Energy Brainpool, explains what parameters the EU taxonomy controls, what conditions are attached should the two technologies be classified as sustainable, as well as summarising those national interests and constraints. Critics say neither should be … [Read more...]
Sustainably harvested Forest Biomass can help replace coal and gas
Burning sustainably harvested wood pellets emits far less carbon than burning coal or gas. Thatâs the main reason why it should be used in the global energy transition, argues Jennifer Jenkins at Enviva. Coal is declining, but not fast enough. Gas consumption is rising. Forest biomass can more easily be swapped in than wind and solar to provide dispatchable power. But it must be done sustainably. Referencing her white paper, Jenkins sets out the … [Read more...]
New EU green investment rules to make conservative German savers bite
Germanyâs past renewables successes have been underpinned by government and public funds and guarantees. Its future will depend more and more on private investment, which means citizens and small investors must opt to put their money into green investments and take on risk. The good news is that surveys show citizens are very willing. The bad news is that few are actually doing it. Is it because the banks arenât promoting sustainable investments, … [Read more...]
Nuclear – critical choice for 2050
As the urgency of the climate crisis becomes more obvious, nuclear power is drawing another look. The power sector needs to develop to meet climate targets. Renewables (RES) have taken significant share of the energy mix in recent years but going further means securing far more investment and solving the complex challenge of integrating variable power. There is a need for alternatives to run alongside RES, keeping us on track. Matthew Wald from … [Read more...]
