Most efforts to decarbonise buildings are focused on “operational” emissions. That’s because, once constructed, buildings are responsible for a massive 30% of global final energy use and 28% of carbon emissions. But that focus has meant the “embodied” carbon – from the materials, construction, demolition, and recycling of buildings – has received little attention, explain Meng Wang and Yihan Hao at RMI. That’s despite the numbers still being … [Read more...]
Re-shaping the EU ETS as a safety net, not a driver
The EU ETS (Emissions Trading System) has struggled to cope with the current economic crisis which has caused a drop in the European carbon price, while the expected drastic drop in 2020 emissions will only add to the existing surplus of allowances. This highlights how necessary it is to reform the mechanism for managing this surplus or even to implement a carbon floor price, explain Charlotte Vailles at I4CE and Nicolas Berghmans at IDDRI. They … [Read more...]
Free online Buildings Electrification training for workers on lockdown
More than 26 million Americans have filed for unemployment benefits during the lockdown. Among their number will be workers who, while sitting at home, could be trained up with useful skills they can use when the lockdowns end. You just need to identify where the big skills gaps in the economy are. Stephen Mushegan and Claire McKenna at RMI look at buildings refits and electrification, where like in most countries huge emissions reduction targets … [Read more...]
The coalition for an EU-ETS carbon price floor is reaching critical mass
The EU Emission Trading Scheme (EU-ETS) is bound to play a major role for ratcheting up climate policies in both the EU and its member states. After a prolonged period of low prices that questioned the ETS’s viability, the recent price run upwards in the wake of a major reform has sparked confidence that from now on “everything goes in the right direction”. But this confidence is misguided and ignores major risks for the scheme, argue Michael … [Read more...]
California fires and blackouts: would non-profit utilities be more reliable, safer, cheaper?
The wildfires in California ignited by poorly maintained transmission lines have themselves ignited a debate about whether the guilty - and now bankrupt - energy utility PG&E (the largest in the state) should now become publicly owned. That in turn has led Severin Borenstein at the Energy Institute at Haas to consider the pros and cons of public v private in this vital activity. The first thing to note is that electricity transmission and … [Read more...]
Creating a market to trade excess wind/solar between states (without outsourcing your emissions!)
How do you get neighbouring states, with different renewables mixes, and different emissions targets and penalties, to trade their surplus energy? It’s one of the biggest challenges to face the rapid growth of intermittent wind and solar. Meredith Fowlie at the Energy Institute at Haas describes how an “Energy Imbalance Market” (EIM) is operating across eight states in the west of the U.S. Bidding for your neighbour’s excess renewable energy is … [Read more...]
Hydrogen Fuel Cell trucks can decarbonise heavy transport
Patrick Molloy at Rocky Mountain Institute runs through the pros and cons of hydrogen fuel cell vehicles (FCEVs). The big pluses are that hydrogen has an energy density of around 120 MJ/kg, almost three times more than diesel or gasoline. Half the energy generated by an internal combustion engine is wasted as heat, whereas electric drivetrains used by FCEVs only lose 10%. Nikola Motors, a U.S. maker of hydrogen trucks, claims its vehicles can get … [Read more...]
Non-Wires Alternatives for grid expansion: what the U.S. can teach Europe
Grid expansion usually means more power stations and wires. Far from simple, and very expensive. Non-Wires Alternatives (NWA) solve the problem differently by reducing net demand. Modern methods of energy efficiency, demand response, storage, and distributed generation are coordinated and used instead, under the banner of Distributed Energy Resources (DER). Crucially, it can cast utility firms in the role of market makers, not just generators and … [Read more...]
